    - freeware .NET graph library needed Hi! I need such library to make UML modeler with which i'd be able to make UML schemas(primarily for designing software projects).What i'm trying to achieve is to make something like any other UML drawing tool. I've found some commercial ones(yFiles.NET, Essential Diagram)and freeware Netron graph library(but it doesn't contain all UML elements). Thanks! Tag: Render window to video port? Tag: 108175

    - Moving the MdiClient area I programmatically moved the MdiClient of my MDI form to be nested inside a Panel so I can control the layout better. I also removed the 3D border on the MdiClient using Interop. When trying to open MDI child forms, I first received an error about the parent not being an MDI container. I suspected this was because I moved the MdiClient, so I set IsMdiContainer back to true after the move. I no longer get the error, but now the MDI children don't display at all. I'm assuming I need to hook the MdiClient back up to the parent form somehow. How do I do this while keeping the MdiClient nested in a Panel? TIA Jared Tag: Render window to video port? Tag: 108168

    - "UpdateEvent" I'm looking for some kind of form level event that I can hook/add/use to tell me when ever some input control has changed its state. As a hack currently I set KeyPreview to true and hooked the KeyPress event. This works great for text boxes etc, but if a user uses the mouse to select someting in a listbox it doesnt catch it of course. The idea is something like this, in the even I want to check the state of the inputs and enable disable for example the Save button. Delphi had a neat way to do this with actionlist and I know there are free and 3P action lists for .NET, but this is an existing WinForms app and I cant redo it. I just need a basic event I can hook to properly enable/disable controls. The other "hack" option is a timer, but thats pretty ugly too. I've also considered hooking into the windows message pipe and ignoring obvious ones like WM_Paint etc, but again I'd like to avoid this and find something else. Anyone have any suggestions? -- Chad Z.

    - Flashing scrollbar on MDI child window after cursor key hit! My application has a main form with its "IsMdiContainer" set to 'true'. I create a form to serve as a child form, setting its "MdiParent" to the main form before calling its "Show()" method. The "AutoScroll" property is set to 'false'. My child form class has two scroll bars which I added manually; an HScrollBar and a VScrollBar. Each of these scroll bars has its "TabStop" property set to 'false'. (As mentioned above, the "AutoScroll" property of the child form class is set to 'false'; I do not want to use the form's automatic scroll bars.) Any instance of the child form properly has its OnKeyDown() handler triggered when the child form has focus and regular keys are pressed. All works great -- until I press a cursor key (i.e., up, down, left, right). When I press a cursor key, one of the scroll bars starts to scroll, and starts to flash! When I release the cursor key, the scroll bar continues to flash, and no other key events are received by the child window. Wait... I just solved my own problem! Override OnPreviewKeyDown(), and then disable each scrollbar (set its "Enabled" property to 'false'), and call Invalidate(false) to put a repaint message in to the queue for the form. When the scrollbars are disabled, this is evidently enough to prevent the cursor key from finding a scrollbar and locking to it, starting the flashing, and capturing the input. Upon repaint we can set the Enabled property of the scrollbars back to 'true' if appropriate. Whew! I thought I was going to have to implement my own "MDI" logic instead of using the "IsMdiContainer" feature. Wow, the worst part about Windows Forms is the crazy logic concerning how cursor key events, mouse wheel events, focus, and other things are handled... What next?! Anyhow, I am sharing my discovery for the benefit of others. --- Colin Tag: Render window to video port? Tag: 108136

    - Multiline TextBox with Autocomplete? I have noticed that Autocomplete stops working when you set a TextBox to Multiline. Is this the designed behavior? Is there any way to make it work, other than developing your own custom control? I would also like to see a behavior where the list of suggested items resets after each space, so in other words you could use Autocomplete multiple times in the same TextBox. Do I have to start developing my own control for this? -- Paul Fountain, Software Engineer InsureMe Tag: Render window to video port? Tag: 108117

    - Is this normal Hi there, Is it normal for form-based events to fire in "InitializeComponent()". I've got a "DataGridView" on a form and I set its "CellValueChanged" event using the forms designer. Ok, VS initializes my event in "InitializeComponent()". However, "InitializeComponent()" later calls "ComponentResourceManager.ApplyResources()" which (to my great surprise) fires my event (which my handler then chokes on since it thinks the window is already running). Looking at the call stack, the event was fired while initializing the header text on one of my "DataGridView" columns (from the resource file). I'm not sure if this particular event should even apply in this situation but in any case, the form hasn't even been created yet. Is it therefore normal for some form-based events to be fired while the constructor is still running. If so then it's potentially dangerous to define events using the forms designer so we should presumably add them ourselves in "OnLoad()" typically (or otherwise design all handlers to check that the window has actually been created which is ugly IMO). Can anyone elaborate on this situation. Thanks. Tag: Render window to video port? Tag: 108085

    - DataGridViewComboBox selectively hide arrow I have a column on my DataGridView that is of the type DataGridViewComboBoxColumn. On some of my rows, I want to keep the user from changing the value in that field. What I'm doing now is, as soon as I populate my rows, I run through each row something like this: private: System::Windows::Forms::DataGridView^ Fields; ... #define COMBO_COL 3 for (int i = 0; i < Fields->RowCount; ++i) { if (it shouldn't be changed) { Fields->Rows[i]->Cells[COMBO_COL]->ReadOnly = true; } } That works, but it both looks ugly and doesn't give the user a clue about why the combo box's arrow doesn't do anything. Ideally, what I'd like to do is hide the arrow altogether for those rows. Does anyone have any ideas about how to do that? One thought is that I could change the cell type on the fly to a regular edit cell. I'm not sure how to do that, or if that would just confuse the control altogether.

    - Drag-n-Drop to Folder or Desktop I have a form that displays a list of bitmaps. I have read the MSDN docs regarding drag-n-drop operations, and have reviewed some examples online on how to do this, but the examples I have seen thus far only show how to create an internet shortcut file. When the user drags an image from the form to the desktop, I would like to either save the image using a default filename (if possible) or show the Save As dialog so the user can enter a name for the file themselves. So, the form with my images (which are in-memory bitmaps and are not stored on the file system) needs to be able to have the images dragged from the ListView control (which are ListViewItem's of course) and dropped onto a specified folder or the desktop (actual folder or desktop, not part of my app)...

    - TreeView & WM_PAINT I'm curious, given the below code, where does .NET perform the drawing of the treeview? I'm especailly interested in how a TreeNode is painted on the screen with a checkbox in front of it. And yes, I'm fully aware of the TreeViewDrawMode.OwnerDrawText and base.SetStyle(ControlStyles.UserPaint, true); options. class TreeViewE : System.Windows.Forms.TreeView { public TreeViewE() { this.DrawMode = TreeViewDrawMode.Normal; } } By using .NET Reflector on System.Windows.Forms.dll I have debugged the issue at bit. It seems the TreeView::WndProc does not handle WM_PAINT message and send it to the base class. The Control::WndProc forwards the WM_PAINT message to WmPaint. Here is where I get a bit lost. The method is pasted in below but its difficult to follow it, especially with "Native" methods being called. I'm assuming at some stage the Graphics object needs to be used to draw text, checkbox etc. private void WmPaint(ref Message m) { if (this.DoubleBuffered || (this.GetStyle(ControlStyles.AllPaintingInWmPaint) && this.DoubleBufferingEnabled)) { IntPtr ptr1; Rectangle rectangle1; NativeMethods.PAINTSTRUCT paintstruct1 = new NativeMethods.PAINTSTRUCT(); bool flag2 = false; if (m.WParam == IntPtr.Zero) { ptr1 = UnsafeNativeMethods.BeginPaint(new HandleRef(this, this.Handle), out paintstruct1); rectangle1 = new Rectangle(paintstruct1.rcPaint_left, paintstruct1.rcPaint_top, paintstruct1.rcPaint_right - paintstruct1.rcPaint_left, paintstruct1.rcPaint_bottom - paintstruct1.rcPaint_top); flag2 = true; } else { ptr1 = m.WParam; rectangle1 = this.ClientRectangle; } IntPtr ptr2 = Control.SetUpPalette(ptr1, false, false); try { if ((rectangle1.Width > 0) && (rectangle1.Height > 0)) { Rectangle rectangle2 = this.ClientRectangle; using (BufferedGraphics graphics1 = this.BufferContext.Allocate(ptr1, rectangle2)) { Graphics graphics2 = graphics1.Graphics; graphics2.SetClip(rectangle1); GraphicsState state1 = graphics2.Save(); using (PaintEventArgs args1 = new PaintEventArgs(graphics2, rectangle1)) { this.PaintWithErrorHandling(args1, 1, false); graphics2.Restore(state1); this.PaintWithErrorHandling(args1, 2, false); graphics1.Render(); } } } } finally { if (ptr2 != IntPtr.Zero) { SafeNativeMethods.SelectPalette(new HandleRef(null, ptr1), new HandleRef(null, ptr2), 0); } } if (flag2) { UnsafeNativeMethods.EndPaint(new HandleRef(this, this.Handle), ref paintstruct1); } } else { if (m.WParam == IntPtr.Zero) { NativeMethods.PAINTSTRUCT paintstruct2 = new NativeMethods.PAINTSTRUCT(); IntPtr ptr3 = this.Handle; IntPtr ptr4 = UnsafeNativeMethods.BeginPaint(new HandleRef(this, ptr3), out paintstruct2); IntPtr ptr5 = Control.SetUpPalette(ptr4, false, false); try { PaintEventArgs args2 = new PaintEventArgs(ptr4, new Rectangle(paintstruct2.rcPaint_left, paintstruct2.rcPaint_top, paintstruct2.rcPaint_right - paintstruct2.rcPaint_left, paintstruct2.rcPaint_bottom - paintstruct2.rcPaint_top)); try { if (this.GetStyle(ControlStyles.AllPaintingInWmPaint)) { this.PaintWithErrorHandling(args2, 1, false); args2.ResetGraphics(); } this.PaintWithErrorHandling(args2, 2, false); return; } finally { args2.Dispose(); if (!this.IsDisposed && this.IsHandleCreated) { ptr3 = this.Handle; } UnsafeNativeMethods.EndPaint(new HandleRef(this, ptr3), ref paintstruct2); } return; } finally { if (ptr5 != IntPtr.Zero) { SafeNativeMethods.SelectPalette(new HandleRef(null, ptr4), new HandleRef(null, ptr5), 0); } } } PaintEventArgs args3 = new PaintEventArgs(m.WParam, this.ClientRectangle); this.PaintWithErrorHandling(args3, 2, true); } } Appreciate any input Tag: Render window to video port?

    - Title bar of Windows form is stuck in resize state when x coordinates and top y coordinate of form are negative Hello, I think I found a bug in the Windows forms engine related to multiple monitors and I wonder if anyone saw that too. If yes, any workaround? Steps to reproduce: 1. connect two monitors to your PC, extend your desktop to both monitors 2. In the monitor settings dialog, drag monitor 2 so that it is to the left of monitor 1. This makes x screen coordinates of monitor 2 negative. Also make sure monitor 2 extends above monitor 1, so that top y coordinate is negative as well. This happens to be my default setup, I have a larger monitor to the left of my laptop screen. 3. Open a sizeable modal dialog in a dotnet 1.1 Windows forms application. 4. Click and hold the left mouse button on the title bar of the dialog, move it to monitor 2. 5. Now release the mouse. 6. Move the mouse over the title bar area, notice what happens. What I see: - If the window is on the left screen and its top is above the top border of monitor 1, mouse cursor is always NW-SE resize cursor over the title bar unless the dialog is maximized. If the title bar is partially above the y=0 coordinate, the strange behavior is only apparent for the part where y is negative. - it is no longer possible to move the dialog by dragging the title bar. Attempting to do so resizes the window rather than moving it - it is not possible to use the [x] button to close the window unless it is maximized - normal behavior will only resume after you manage to move the window back to monitor 1 by resizing it. This will not be possible at all unless the "show in taskbar" property of the Window is set and maximize is allowed. Tag: Render window to video port? Tag: 107997

    - ???Dispose dynamic menu items Hi People I have a WinForm program. The UI contains a ToolStripDropdownButton, which is associate a list of menu items of ToolStripMenuItem, created dynamically. Upon different scenarios of user operations, the DropdowButton need to clean up all its menuitems, and create new ones. Here the codes: //////////////////// Void CreateForEmail() { ... button.DropDownItems.Clear(); ... button.DropDownItems.Add("To:", null, HandleOutlookToClick); button.DropDownItems.Add("CC:", null, HandleOutlookCCClick); } Void CreateForPhone() { ... button.DropDownItems.Clear(); ... button.DropDownItems.Add("Phone", null, HandlePhoneClick); } Void CreateForNone() { button.DropDownItems.Clear(); } //////////////////////// So far so good, just work as I expect. Later on, I found out that " button.DropDownItems.Clear();" does not dispose the menu items at all, when I decided to add shortcutkeys to menu items. The above codes were changed in order to have shortCutKeys: //////////////////// Void CreateForEmail() { ... button.DropDownItems.Clear(); ... button.DropDownItems.Add("To:", null, HandleOutlookToClick) .ShortcutKeys = Keys.F9;; button.DropDownItems.Add("CC:", null, HandleOutlookCCClick); } Void CreateForPhone() { ... button.DropDownItems.Clear(); ... button.DropDownItems.Add("Phone", null, HandlePhoneClick) .ShortcutKeys = Keys.F9;; } Void CreateForNone() { button.DropDownItems.Clear(); } //////////////////////// After CreateForNone is called, and I press F9, either HandleOutlookToClick or HandlePhoneClick will be called, depending which one was last called. Obviously, those menu items are still in the program accepting keyboard shortcut, though they are not invisible. So I replace "button.DropDownItems.Clear();" with the following //////////////// private void ClearButtonDropdown() { for (int i = Button.DropDownItems.Count - 1; i >= 0; i--) { ToolStripMenuItem m = Button.DropDownItems[i] as ToolStripMenuItem; Button.DropDownItems.Remove(m); m.Dispose(); } Button.DropDownItems.Clear(); // even GC.Collect() will not have effect. } /////////////// However, strange things remain the same. Obviously someone is still holding references to those menu items, stopping GC from disposing those items. Can you point out how to dispose these menu items?

When I view the table in a DataGridView, some of the numbers, which only have two decimal places in the database show up with *15* decimal places and are ever so slightly off (in the example in the subject line, by about 2E-15). I'm not doing any operations on this column. It's just running a stored procedure which performs a pretty basic SELECT on the table. If I run the stored procedure in Management Studio Express, all numbers show up fine (just two decimal places). What's going on here? Thanks, -Dan Tag: Render window to video port? Tag: 107950

    - OnClick preceding OnEnter VS 2005 w/SP1 / XP Pro w/all service packs One of our forms has a Tab-control onto which is dynamically added a number of other controls. When the added controls are ComboBoxes or CheckListBoxes, their OnClick event is fired before their OnEnter. For other controls on the Tab (e.g. ListBox) the events occur in the expected order -- Enter and then Click. On other forms where the controls are added to a Tab-control at design-time, the Enter / Click also occur in the expected order. Does anyone have any idea why on this form the Click (and MouseClick) event would precede the Enter event? -- // Lee Silver // Information Concepts Inc. Tag: Render window to video port? Tag: 107944

    - Master details The FAQ I referenced earlier showed how to catch a double click so you could open your second form. But it seems your question has more to do with displaying the data in the second form that is related to the clicked row in the first form. I think you could use a Master-Details technique to do this. The DataTable on second form can be considered a details DataTable related to the clicked record from the Master DataTableon the first form. Here is another FAQ link discussing how you can use ADO.NET relations to display such Master-Details grids. http://www.syncfusion.com/FAQ/WindowsForms/FAQ_c44c.aspx#q780q ================ Clay Burch Syncfusion, Inc.

    - MI5 Persecution: Dirk Gently on the Toronto Case Dirk was on the West Coast when he got the call. An old friend at the Toronto police department thought he would like to fly up and take a look at a homicide which had occurred the previous evening. He decided to skip the last day at the World Holistics conference and take the next plane out of San Francisco. The flight was bad; Dirk had been hit on the back of the head by the Newspaper trolley, the drinks trolley, the dinner trolley and now the gift trolley. When the hostesses weren?t trying to tear his arm off they pestered him to stop leaning into the aisle - ignoring the fact that the guy next to him was taking up one and a half seats. Air Canada used to be the flight which was so good you just didn?t wanna get off - on this occasion Dirk would be glad to see the back of the plane and the over sized alternative comedian wedged into the window seat. After breathing in a couple of lungfulls of crisp Canadian air Dirk took a taxi into town. There was a small group of demonstrators outside the MacDonalds and the taxi driver insisted on stopping on the opposite side of the street. ?Don?t Eat Meat? the placards read and the demonstrators chanted. A couple of policemen where stopping the crowd entering the restaurant itself - one held up his arm and challenged Dirk. A wave of the fax he had been sent and the policeman pushed open the door. There were few customers in the restaurant. Not surprising really with a demonstration going on outside, half the dining area roped off with tape and a dead body seated at one of the tables. ?Mr Gently sir? the officer in charge called out as he peeled one end of the tape off a column ?We were told not to touch anything til? you got here?. The body of the man slumped awkwardly in a chair. Then even a dead body would start getting uncomfortable in a MacDonalds chair after twenty minutes - and this one had been there for at least eighteen hours. Two back legs and the tail of a cat hung out of the man?s gaping mouth. Dirk turned to the officer, ?I suppose you are going to tell me this is the darndest thing you ever saw?? ?Ain?t this the darnd...?. The officer seemed annoyed that Dirk had second guessed him. ?We?re removing the body in a few minutes, so if you can get through as quick as possible? ?Many people eat cats in fast food restaurants?? Dirk asked and without waiting for an answer leant over the table to pick up an untouched burger. ?And what?s this?? he asked waving it in front of the officers face. ?It?s a Vedgie Burger? The waitress, who was cleaning one of the adjacent tables, shouted across. She walked over to Dirk. ?We started doing them because of that lot out there? she nodded towards the protesters who were pressing there faces against the windows ?They?re called Linda McCartney Vedgie burgers - ever heard of them?? Dirk suddenly felt faint, perhaps a combination of hunger and jet lag. ?This is deja vu all over again? he thought to himself. He glanced at policemen - at the badge on his shoulder ?OPD? but this wasn?t Ontario this was Toronto. OPD - Officially Pronounced Dead. It dawned on Dirk what was happening, he knew what he would see if he looked out of the window. Sure enough, there it was, the Volkswagen Beetle parked across the road - number plate 28IF - 28 IF Paul McCartney had lived. And amongst the lyrics of the song blaring out into the restaurant he could pick out the words ?I buried Paul?. Now it was though Dirk was viewing the whole scene though a TV screen. This was conspiracy. Not -a- conspiracy, or -the- conspiracy, but just plain conspiracy. ?You look faint - are you OK mister? The waitress asked. Dirk shook his head ?Probably a bit hungry? Then to economise on dialogue took out a pack of cigarettes and held it out towards the girl. She was about to take one but Dirk snatched the pack away, held it up to his mouth and drew out two cigarettes. He lit both then passed one of them to the girl. It was the closest he had come to a sexual encounter in three months. ?Want a Burger?? the waitress asked. Dirk looked down at the Vedgie Burger on the table. ?No thanks - just a plate of fries? The waitress walked away and Dirk looked around the room. Apart from a family seated in the far corner there was only one other person in the restaurant - and he wasn?t eating. The guy was about mid twenties and had straggling, shoulder length hair. On the table in front of him were lots of pieces of paper cut into squares. Every so often he would pick up a camcorder and pan it around the room and then, when he was finished, speak into a microphone which was attached to a tape recorder. Dirk walked over to where the man was sitting. The small pieces of paper had paragraphs of text written on them and were stuck to the top of table with blobs of mustard. Lines had been drawn, some solid some dotted, on the table top with a marker pen. The lines ran from one piece of paper to another. ?What are the lines for?? Dirk asked, realising straight away that ?What the hell are you doing?? would be more appropriate. ?You see? The man replied nervously ?The dotted lines are weak links and the solid lines are strong links. The dotted lines are things which are happening in the rest of the world and the solid lines are things which are happening to me. Now you see I draw over a dotted line, replacing it with a solid line, when I can link something back to me. Like this? The pen squeaked over the Formica and before Dirk could interrupt the man added. ?You see I lost my short term memory and, as a consequence have a very short attention span. I write down, record and film everything then put it all together later? ?So? Dirk interrupted. ?You filmed what happened here?? ?Yes, yes, it?s here on this tape? The man pushed the cassette across the table. On the label the words ?Grassy Knoll? had been crossed through and replaced with ?MacDonalds?. Suddenly the man sprung from his seat. Dirk turned and saw that the body was being removed on a stretcher. As it passed the man picked a small object off the edge of the stretcher itself. ?This is important? he said, laying a blood stained bullet on one of the small pieces of paper on the table. Suddenly the room was filled with a deafening throbbing sound as a Black Helicopter landed in the street outside. Two men in United Nations uniforms got out and collected the stretcher. Back at the table the long haired man was replacing all the dotted lines with solid ones. Dirk panicked and began to walk backwards at some speed. Barging through the swing doors he stumbled into the kitchen, tripped and felt himself sink slowly into a large vat. ?The guys fallen into the batter? Dick heard someone shout before he sunk below the surface. He came to sitting in a chair with the batter solidifying all over his body. He surveyed the room through two eye-holes someone had cut. Suddenly the chair on which he was sitting was picked up carried through the restaurant and out of the building. As the chair was being lifted and put into the back of a van, Dirk caught a glimpse of the waitress following him. ?Your fries mister, your plate o...?. The doors of the van shut and Dirk tried desperately to steady himself as it sped across town. Eventually the doors flew open and Dirk was flung into the road at which point the solidified batter shattered and set him free. Standing up he found himself outside the international departures terminal of Toronto airport. In the departure lounge Dirk had time to reflect on the day?s events. He had got caught up in the conspiracy theories and the haphazard welding together of pieces of irrelevant information. It was time to catch the person who was operating the bizarre cognitive engine which appeared in front of him like a fairground mirror, distorting any flaw it could find in his own, fragile, map of the real world. Dirk leant into the aisle of the plane as it took off for London. The oversized person next to him swung his arms violently as he complained about every thing from the supper in a plastic tray to the state of British politics. With a shaven head and a badly fitting suit the man looked as though he could have worked behind the reception desk of the Kremlin. However when he spoke he did so in a Liverpudlian accent. ?Me I blame the Con-serv-a-tive government, me. The Tour-rees. That-cher. Me. They need a good kicking? He jerked his feet forward and struck the seat in front with his Doc Martins. ?With these. Me Doc Martins. Doctor Martin?s, Doctor Martin?s, Doctor Martin?s Booots!? The phrase was now being sung over and over again as the man writhed in his seat and clicked his fingers. Dirk looked down at the boots and thought of the reaction most people used to deal with the paranoids at the end of the wire. A nice quick kick. ?Oi nutter - get some therapy?. This is the easy way out and perhaps the safest. After all there you are sat, alone, in front of the screen. No body language between you some paranoid. No way of telling if he really is some gibbering psycho. Look at it too long and you be drawn in. Fall into the tangled database of weird links with him. Who knows he may be watching you, reassembling and linking your experiences with his. How sure are you of you own cognitive threads. After all cognition is only a bug fix for a neurological system which was designed in a hurry - it?s abused by everyone from politicians to advertisers. If people really can convince each other that a bottle of washing up liquid is as exciting as an orgasm using just television God knows what they can do with a computer. Better to avoid the risk. A swift kick. After all if you?re Homophobic you put the boot in because you are scared of any ambiguity in your own sexuality - why not be Nutterphobic as well. Although Dirk would have liked to devoted time to tracking the culprit down he decided to let it rest. The Internet changed over the next twenty odd years. A lot of the people who used it went out and got lives. And those who already had lives burnt them away. The number of users had dwindled after someone had invented a C++ program, with truth as a variable, to deal handle politics and government. Dirk had already retired from finding old ladies cats with the help of obscure science when he got another call from Toronto. It was 4th March 2025 when he booked onto the Air Canada flight from Heathrow. The silver haired woman in the seat next to him painted bright red lipstick around her mouth. ?Of course it was no surprise to be offered the job after Claire Raynor retired? she sneered? After all I used to be a psychiatric nurse... Now if Blokes had periods they would understand...? By chance the taxi ride to Toronto mental hospital took him past the MacDonalds - where the whole thing had started. Of course it was barely recognisable having become a Church Of Scientology Vedgie Bar. Police in riot gear kept the two sets of demonstrators apart. Dirk didn?t really know what to expect when he got to the hospital. The girl at the reception desk directed him to a row of chairs in a wide well lit corridor. There was a strong smell of disinfectant, the furniture and the carpets were immaculately clean and behind the rows of teak veneer doors the ?nutters? were all safely locked away. For some reason Dirk started thinking about CompuServe forums. A tall blond woman in a white coat approached. ?Mr Gentle, I assume? ?Yes? Dirk replied shaking her by the hand. ?You?re the nurse who...? ?Doctor? She interrupted, ?Doctor Killfile? She led Dirk across the corridor towards one of the doors then stopped with her hand resting on the handle. ?Now you know about this person don?t you?? and after Dirk nodded she continued ?Don?t tell him anything about yourself - don?t let him get into you head. If he does he?ll screw it up? The door opened to reveal a frail man sitting in from of a TV screen. He had a keyboard on his lap and next to the television was a computer screen. Dirk glanced at the walls of the room and remembered that his settee at home need upholstering. The nurse left the room and the man looked up ?So you come to my daughters wedding and ask me to kill a man? he said in a dry cackling voice. ?Look? he continued, pointing at the screen, ?I know that man. They?re talking about me now - listen?. The man stared at Dirk. ?What?s your name? Are you one of my friends from the Internet? - Are the lambs still screaming Dirk?? Dirk, at first recoiled in horror, then felt a sense of anti climax. So this is what they hyped up to superstar status on the back of their own fears of madness. Dirk was reminded of the film ?A day on The Beach? where a submarine had set off to search a post nuclear World to track down a signal coming from a remote military base - only to find it was being sent by a Coke bottle half balanced on a Morse tapper. Outside the room the nurse waited for him. Because his nicotine craving had returned - and to avoid an awkward piece of dialogue - Dirk turned to her and asked . ?Patch?? Dirk took two nicotine patches from his wallet the first of which he stuck onto the inside of his arm. Stepping closer to Doctor Killfile he opened her white coat and slid his hand into the opening at the front of her dress. He pressed the patch onto her leg as close to the top of her inner thigh as he dare. She took a deep breath and then slowly breathed out. ?What Bogart could have done with these things? Dirk thought to himself. ?Is he crazy?? Dirk asked tilting his head back to towards the door. ?Who knows? Doctor Killfile replied ?We let him type away. He sees something on the TV in the morning and it keeps him busy all day. What he types doesn?t go anywhere it just stays on a mainframe in the basement. It can be read by anyone else in the building but that?s it. We got them all in here conspiracy theorists, racists, nationalists. They?ve created a world within a world really...? Her voice trailed away and she stared down the corridor for a while then added ?So long are two things are different neither will come to be in the other and so become at once both one and two.? Dirk gave her a puzzled look ?You mean their brains are fried?? ?Fried?? Killfile smiled at Dirk ?No that was Plato?. Then the smile fell from her face. ?You must remember, mister, plate o...? 719 Tag: Render window to video port? Tag: 107918

    - MI5 Persecution: Security Service Tribunal Denies Security Service Tribunal Denies In June 1997 the Security Service Tribunal wrote to me regarding the complaint I had brought against MI5 in February. They say, The Security Service Tribunal have now investigated your complaint and have asked me to inform you that no determination in your favour has been made on your complaint. Again, I do not believe their denials. I think MI5 *has* taken the action against me as described, and is refusing to admit what they have done. To the best of my knowledge, the Security Service Tribunal has *never* found in favour of a complainant. This tends to strongly suggest that MI5 lies on a routine basis, and the Tribunal can't fulfil its functions in the face of Security Service falsehoods. 719 Tag: Render window to video port?

    - The Infamous DateTimePicker I have what I consider to be an unusual issue. In the past, I've not used data-binding with the DTPs. So I'm finding some of the old issues raising their ugly heads in a new fashion. First a caveat: All other controls and data work properly on this form. Updates, deletes, inserts, all as advertised. The DTPs are bound to smalldatetime columns in the database. The bindingsource is bound to the table, the controls to the bindingsource. The DTPs are set up as follows: ShowCheckBox = True Checked = True Format = Short My understanding of the DTP in the past has been that an unchecked control indicates a null. In the past, when I manually saved the values from the DTPs, I could save a null back to the database. But now, when I uncheck a DTP and save, the originally saved date remains in the database. If I change the value in the DTP (even if unchecked), the value in the database changes. So what gives with the binding? How in the world to null a value from the DTP when it is bound? Finally, who created this godforsaken control!? Tag: Render window to video port? Tag: 107903

    - Accessing form's text box from Module I have come from a VB6 background, and I'm trying to convert an MDI app that has many subs in modules which directly access a textbox in a child form of the main MDI form (frmMain as MDI form, frmEdit as child form, txtEdit as richtextbox) code: With frmMain.ActiveMdiChild.txtEdit I totally understand OO concepts now, which I didn't (completely) when the app was originally written, but I really don't want to re-write every single sub and make it a function, to output text - that would make me want to shoot the computer. I guess, the other option would be to put all this stuff in the MDI form or MDI child, however, that would really bloat those forms....(IMHO) Is there a way to reference the textbox on the child form, directly inside a module, with VB.Net (2005)?

Is it possible to redirect the rendering of a windows form to the video
port/overlay device of a video card? In my situation I must present the
contents of a window on an hdtv and I can't use a desktop clone trick
because there's going to be another application running that cannot
show up on the tv. Any ideas?

Can you extend the desktop onto the HDTV and restrict the one window to
it while restricting the other application to run on the main monitor?

I'm going to give that a try. The only downside is if one of the
applications doesn't remember which desktop it's supposed to run in, I
won't have programmatic control to fix it. I really need to isolate
each desktop so an application from the main one can't be dragged into
the hdtv one.
