    - BackgroundWorker Capability For Non UI Classes I like the concept and features of the BackgroundWorker. However, I observed that it will only work for clients that implement ISynchronizeInvoke (namely forms and controls). My instinct is that BeginInvoke uses windows message loops to synchronize back to the main (UI) thread. I want this same capability in a business level component so that it can fire client delegates on the main (UI) thread if it did some asynchronous work on a background thread, but I don't want to have to force it to carry around a full 'System.Windows.Forms' form so that I can kludge the BeginInvoke methods. Is there a ligthweight WindowImpl that I can programmatically use to post messages to and handle the callback in a WndProc on the main UI? In ATL I would create a simple CWindow and host it without a resource file for it or a visible window. I could receive messages from it and use it to perform worker thread synch. Is there anythign comparable in .NET? Or must I carry around the weight of a complete System.Windows.Form? Thanks, -- Brian R. Tag: How to document architecture of an application? Tag: 98936

    - .NET 2.0. ComboBox databinding bug ? Hi, I hold data in memory (DataTable) which is updated/merged every 60 seconds (this all is done in new thread). Now, i have a form and this form contains one ComboBox. I'm creating new DataView from DataTable i hold in memory and set this DataView RowFilter to filter some rows. There is also opened a second form which contains only a datagrid that is binded to a same DataTable but thru new DataView and a same RowFilter is set. If new data cames from server, this datagrid is updated without any problems (new rows, changed, deleted), but on first form ConboBox is not updated. Anyone know why this happends?

    - Painting textbox portion of the combobox Hi , I am trying to make the text on the combobox appear in black when the combobox is disabled. Since there is no easy way to it, i decided i had to draw it myself. But the combobox OnPaint event paints only the border and the button portion of the combobox. The textbox portion of the combobox was not accessible. So i had to use Win32 functions to get an handle to the text box portion of the combobox. But again the painting of the textbox portion of the combobox works fine when the combobox is enabled but it does not work when the control is disabled even though the OnPaint and the same code is getting executed. Any ideas? I am pating the piece of code i am using to draw on the textbox portion of the combobox. Please excuse the colors in the code as it only for testing. The code works fine when the combobox is enabled but not when it is disabled. When disabled the textbox portion of the combobox always remains gray. Also when enabled the painting in the code happenes only when the mouse enters the textbox area of the combobox. RECT rt = new RECT(); IntPtr hdl = FindWindowEx(this.Handle, IntPtr.Zero, "EDIT", "\0"); GetWindowRect(hdl, out rt); Graphics g = Graphics.FromHwnd(hdl); Brush br = new SolidBrush(Color.Green); g.FillRectangle(new SolidBrush(Color.Red), new RectangleF(0, 0, rt.right - rt.left, rt.bottom - rt.top)); g.DrawString("Cool", new Font("Ariel", 10), br, 0f, 0f); Thank You, Vish Tag: How to document architecture of an application?

    - Add Icon to Titlebar (right side) I would like to add an icon to the RIGHT side of an application's titlebar. Basically, it will supplement the other icons already there. Is there any direct support in .NET 2.0 to do this? If not I assume I would have to subclass the windows form but what exactly would I do there? Also how can a make sure that the icon keeps the same style as the other icons? Ideally, there would be some "empty" icon (for instance a minimize icon without the minimize sign) and then I could simply draw on this icon or merge it with another icon that has transparancy for the background.

    - DataGrid with drag and drop, need to control rowstate. Hi, I'm displaying a datagrid when the user enters (highlights) a certain text cell on a row it does a lookup of possible matches. The matches are displayed in a listbox and one of those matches can be quickly tossed with the mouse over to the grid surface and replace the original cell text. In the datagrids DragDrop event I'm using BeginEdit() EndEdit() on the Row where the change takes place. But this does not leave the DataSets Rowstate for that Row as Modified? I hoped to use the rowstate as a condition for updates (one or many) The grid works (Rowstate is correct) when the certain text cell that is the source of the lookup is keyboard edited or other grid type functions.

    - Override WndProc is stopping shutdown Hello, I am overriding the WndProc in my main form of a Windows application and the design is for it to ask for some info, kill the application, and continue on to either shutdown or restart. This is working fine for the go into hibernation or standby mode, however with shutdown, it stops after receiving the advice and killing itself. Here is my code: if (m.Msg == WM_SHUTDOWN) { m.Msg = WM_SHUTDOWN; m.Result = (IntPtr) 1; KillAgentWithStatusChange(); //this asks for information and than kills the application base.WndProc(ref m); return; } The reason I am killing the application is because Windows (for some reason) won't shut down with the application running. Even after removing this code, it still does not do the trick. What in the application could cause Windows not to shutdown when prompted? Many thanks in advance!

If you have a gridview with a combobox column with values; value1, value2, and value3 and you need to bind to a datasource that could have "invalid" values that are not in that list say value4. How can you handle this situation? I would like to show the invalid value and let the user choose a valid value from the combobox but if they don't touch the cell I want the "invalid" value to stay.

    - NTD and Enterprise Library I am having trouble using No-Touch Deployment (NTD) and Enterprise Library. The application works great when simply clicking on the executable without going through the browser, but when trying to execute with the browser or IEExec.exe the application cannot read Enterprise Library's config files. Also, I do not see where the client is doing a "GET" for the enterprise library's config files in IIS logs. If I remove any references to Enterprise Library, then the application works great for NTD. I am using 1.1 framework. Can NTD only read one config file and it is not smart enough to get additional config files? I have searched the Internet up and down and cannot find anything useful.

    - Scrollbars I'm trying to use the HScrollBar and VScrollBar controls, but I'm having some problems with them... I want them to just sit there and let the user drag them, so I can retrieve the thumb position and handle everything else in my code. Furthermore, I want to control when they appear and when not.

    - Referencing item on form with added to tab object as control Hi, I have an application where on the main form I have a tab control. I also have created a form that has 2 text boxes and a couple of buttons on it. When the main form loads I run this code Dim MyForm2 As New frmQuery MyForm2.TopLevel = False MyForm2.Show() MyForm2.Dock = DockStyle.Fill MyForm2.Anchor = AnchorStyles.Left MyForm2.Anchor = AnchorStyles.Top Me.TabControl1.TabPages(0).Controls.Add(MyForm2) Me.TabControl1.TabPages(0).Controls(0).Anchor = AnchorStyles.Top Or AnchorStyles.Left Or AnchorStyles.Right Or AnchorStyles.Bottom Me.TabControl1.TabPages(0).Controls(0).Dock = DockStyle.Fill Me.TabControl1.TabPages(0).Focus() This creates an instance of my form and adds it to the tab. This works fine. Now I want to load a file into on of the text boxes on the form frmQuery. How do I reference it from the Main form?? I think I would start with TabControl1.TabPages(TabControl1.SelectedIndex).Controls(0)...... but I'm not sure what goes next. Intellisence cannot pickup the objects on frmQuery because it is loaded at runtime. Does anyone have any ideas Tag: How to document architecture of an application? Tag: 98867

    - Problem with using TopMost property Hi, I am having a few problems with using the TopMost property for dialogs. The problem centers around the fact that I have a main dialog which as a central map and at certain positions on this map I need to display small message boxs to represent information regarding this point. These message boxs are simple forms with a ew text fields and labels. The problem I am having is that I need to set the TopMost property of the forms to true if I want to see more than one message at a time. I am creating these message forms dynamically when the user clicks the correct positon on the main map. What happens is that after the first message form, the second one makes the first one disappear under the main form. If I set the TopMost property then they all appear but when I minimise the main form, the message dialogs remain on the desktop. if (e.Button == MouseButtons.Left) { Point pt = new Point(e.X, e.Y); foreach(IconDetails icon in icons) { Point pt1 = icon.GetLocation(); Rectangle rect = new Rectangle( pt1.X, pt1.Y, 30, 30); if (rect.Contains(pt)) { VMSSiteObject vmsObj = vmsSiteObjects.GetBySCN(icon.GetDescription()); if (vmsObj != null) { ArrayList listOfDisp = (ArrayList)vmsObj.VMSDisplayObjects; ArrayList disp = (ArrayList)listOfDisp[0]; int mods = disp.Count; site = new siteDlg(vmsObj); sz.Width = site.Size.Width - 8; if (mods > 1) sz.Height = site.Size.Height + ((mods-1) * 8); else sz.Height = site.Size.Height; } break; if (site != null) { site.Tag = icon.GetDescription(); siteDlgs.Add(site); site.Show(); site.Size = sz; } } } } Is there another way I could show these forms without having to set the TopMost property.

    - Ctrl+Enter on a combobox automatically selects item beginning with Does anyone know why pressing Ctrl+Enter (with the focus on the combobox) automatically selects the first item in the combo beginning with the letter J? Surely this has to be a bug in the combobox. The problem can be reproduced by simply creating a new Windows Application, adding a new combobox onto Form1, setting it's style to DropdownList and pasting the following code into Form_Load: ComboBox1.Items.Add("Motorbike") ComboBox1.Items.Add("Car") ComboBox1.Items.Add("Jeep") ComboBox1.Items.Add("Van") ComboBox1.Items.Add("Tank") ComboBox1.SelectedIndex = 0 Whichever item you have selected, pressing Ctrl+Enter causes Jeep to become selected.

    - MdiWindowListItem - Is this a .NET bug??? Hi, I think I've come across a bug in the framework. It is to do with the MDI behaviour of the MenuStrip control. From my understanding once the MdiWindowListItem property of the MenuStrip control has been assigned to a ToolStripMenuItem it should assume the responsibility of tracking all MDI children that are opened/closed. This behaviour seems to fail in the following scenario If on the FormClosing event of an MDI child (for arguments sake we'll call this FormA) the form Close is cancelled i.e. e.Cancel = true; and a new form created (FormB) and shown/displayed, the original form FormA dissapears from the window list and is replaced by FormB. So when FormB is closed the window list shows no windows but yet FormA is still open. I know this may sound a little confusing, so I've knocked up a small harness (see link below) which reproduces this behaviour. 1. Open up the solution and start the solution 2. From the File menu select new (creates a new MDI Child window. NOTE: at this point the window list is OK) 3. Close this form by pressing the X (a 'New Mdi Child 1 Dialog' is created. NOTE: at this point the 'New Mdi Child 1' entry in the window list has dissapeared) 4. Press the Cancel button on the 'New Mdi Child 1 Dialog' to close this form http://development.gnitouch.com/MdiWindowList.zip Thanks in advance Tag: How to document architecture of an application?

Thanks in advance for any ideas. Ant Tag: How to document architecture of an application? Tag: 98832

    - DataGridComboBoxCell manual initialization Hello, I have an unbound DataGridView, one of the columns of which is a DataGridViewComboBox Column. The combo box contains several entries that the user can choose from. I use this grid view to accept data and save it to a file. Later the user can edit data as well. While displaying existing data, I try to set the combobox cell index to one of the existing values of the combo box items, but this doesnt work at all. The underlying pseudocode : during initialization - get the underlying combobox control of the cell set the ComboBox.SelectedIndex to the index corresponding to the item for which we have the value. Any help is very much appreciated. thank you. Tag: How to document architecture of an application? Tag: 98831

    - J# rookie: how do I navigate between forms in an application??? I have several Windows Forms that are supposed to work together in one application. The initial form is a main menu with different buttons that, when clicked, are intended to open another form in the application. For instance, there is an "Administration" button that should open an Administration Menu form; there is another button entitled "Data Entry" that should open a Data Entry Menu form. I have designed all the individual forms for the application, but I don't know the code to use in the click event handlers that will result in the desired form to be opened after a particular button is clicked. For instance, what code would I place in the Admininstration_Click event handler that would result in the Administration Menu form opening if the user clicks the "Administration" button? Any help would be greatly appreciated! Thanks to anyone who responds! Tag: How to document architecture of an application? Tag: 98825

    - Help Visual C++ 2005 Express MVP's and experience programmer's only please!... I need to get the number of lines in a textbox so I can insert them into a listview. The text comes from my database and is unformatted. I display the text to my user in the listview. The textbox I create logically in the program, and I initialize the correct properties for a normal multiline editor. When the user changes the column size then I reload the lines accordinally. The problem I am having is when I get the lines property which is a array<^>^(). The lenght is always 1 no matter how many lines are in the textbox. In MFC when the lines are wraped the new line character is automattically inserted, but here it's not. Can you help me solve this problem? I would really appreciate it!
