    - SystemParametersInfo call hanging. Due to the nature of our application, it is necessary to set a system setting that increases the size of the scrollbars when the application is the "active" one. When it is not, the system setting is reverted so that the scrollbars appear in their normal size. To achieve this, I am overriding the WndProc method and checking if the message received is WM_ACTIVATEAPP, (this is the message received when the application gets focus). Upon receipt, I make a call a call to the user32.dll call SystemParametersInfo to make a change to the scrollbar size. This seems to work just fine, but when my application receives a SystemEvent.PowerModeChanged or SystemEvent.DisplaySettings event, my call to SystemParametersInfo (called via the WndProc override) seems to hang... and I can't figure out why. Does anyone have any ideas on why the call to SystemParametersInfo would hang? It requires the user to kill the application. Thanks, Tag: Print Dialog Tag: 108210

    - Windows CBT Hooks (Help!) I hope you can answer a question. I am writing a poker utility that tracks what windows are open and displays information about opponents that are still playing and their previous history that is stored in a game DB. It is a very cool project with Pattern Recognition (Pixel Screen SCraping to OCR) and pretty advanced calculations. I just started writing my first prototype in C# and discovered that I could not set a System Wide CBT hook. .Net will not allow hooks CBT hooks to be set globally, period! Works for mouse and keyboard, but not CBT. I need to trap when a window is created, destroyed, gotfocus, or resized. I do not want to cancel or redirect those messages. I just need to get new rect information about the window. I have discovered ways of doing it in either VB6 or C++. I am not sure which is the best strategy to pursue. I do not code in either language. Can I have this hook in VB or C++ and then call my C# function? Anone have any suggestions for interacting in between managed and unmanaged code when the unmanaged code needs to trigger a C# method? Thanks, Andy Tag: Print Dialog Tag: 108201

    - ImageList performance problem Hi all, I'm experiencing performance problems when adding a large set of bitmaps to an ImageList. The bitmaps are 55x55 pixels in size, which matches the ImageList's ImageSize property. Adding approx. 5000 bitmaps takes about 1,5 minutes. The bitmaps are generated from scratch, resized and other things much faster than that (in just a few seconds) so why should adding them to an imagelist be so slow? The imagelist is also the source for a ListView, which displays the results. I've tried adding the bitmaps to the ImageList via Add(), AddRange() and using the async. virtual mode. The latter sounded promising, but didn't help. Any ideas, hints? Cheers, Johan Sj=F6str=F6m MSc, MCAD, MCTS, MCITP Tag: Print Dialog Tag: 108199

    - 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: Print Dialog 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.

    - 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: Print Dialog Tag: 108136

    - 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: Print Dialog 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. Tag: Print Dialog Tag: 108077

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: Print Dialog Tag: 108036

    - 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: Print Dialog 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? Cheers Andy Tag: Print Dialog Tag: 107973

    - Why does 28.08 show up as 28.080000000000002 in DataGridView I'm baffled. I have a column in a SQL Server Express database called "Longitude," which is a float. 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: Print Dialog 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: Print Dialog 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.

I need to programmically close a PrintDialog form after it is displayed with
the "ShowDialog" method in case the user does not dismiss it himself. My app
needs to have it time out. How can this be done ?

Just before you call ShowDialog, use the BackgroundWorker to spawn a
thread to start a Timer which will call Close on the dialog when the
timer elapses. Make sure that WorkerSupportsCancellation is set to true
and that you check the CancellationPending property before you close the
form.

Does this make sense?
