    - Main Form's Display chops Right Side & Bottom Hello, It seems that on a certain machine (i.e. Dell Dimension 4500S) when the main form is displayed (it initially comes up maximized, and AutoScale is True per the default - not that I truly grasp its significance) parts of the right and bottom portions of the form are not being displayed at all in the window. They seem to have been truncated from the display. I have a textbox that is located (and anchored) on the far right-hand side of the form and when it comes up more than half of the text is just chopped off (a good 2 logical inches or so). The bottom of the form has two rows of icons (24x24) that don't show up at all (these icons are also anchored to the bottom of the form). You can't ever get the form to show any of the "lost" area either (ie. by resizing, minimizing, maximizing, etc.). Has anyone seen this behavior at all or has any ideas as to what is causing this behavior? Is there some known issues with cetain computer's video drivers (this Dell Dimensions uses an Intel video driver) and .NET. After looking around on the net I haven't seen this addressed. On this particular machine "normal" apps seem to work fine and this is the first .NET form application it's ever seen. Thanks for any help/insight, JB Tag: Share a connection Tag: 61878

    - Maximum height of windows form Hi, I am trying to set the height of a form in the VS .net IDE, and somehow seem unable to set the height beyond 780. I have set the autoscale and autoscroll properties to true, and the Miniumn size and maximum size are set to 0,0 each. I was under the impression that with these settings I could make the form as big as I wanted, and could get the scrollbars automatically when needed. However this doesnt seem to be happening. The height gets reset to 780 if i type in anything bigger than that. Am I missing something here ? Does anyone have an idea why I see such behavior ? Thanks in advance for any help, Aniket Sule Tag: Share a connection Tag: 61876

Could anyone please tell me how to only DrawImage the portion I need so it will go faster. Thank you! For now I do: protected override void OnPaint(PaintEventArgs e) { base.OnPaint(e); e.Graphics.TranslateTransform( AutoScrollPosition.X, AutoScrollPosition.Y); e.Graphics.DrawImage(offScreenBmp, 0, 0); System.Drawing.Size s = new System.Drawing.Size(); s.Width = 0; s.Height = 2100; AutoScrollMinSize = s; } Tag: Share a connection Tag: 61861

    - Problems with MessageBox.Show I'm experiencing a problem where I have a non-modal toolwindow that contains a control derived from System.Windows.Forms.ComboBox displayed in an MDI application. Whenever a .NET message box is displayed in the application the derived combo boxes on the toolwindow appear to lose their base control, i.e. base.WndProc(ref m) in the derived control's WndProc results in a NullReferenceException. Admittedly this could be a problem with the derived controls, however after looking at how System.Windows.Forms.MessageBox works it seems like there are some "oddities". Also, if I call the Win32 MessageBox function directly via p/invoke, specifying the correct owner window, then everything works fine. Here is the section of System.Windows.Forms.MessageBox (ShowCore) that I've been looking at: if ((owner != null) && ((options & 2228224) != 0)) throw new ArgumentException(SR.GetString("CantShowMBServiceWithOwner"), "style"); IntSecurity.SafeSubWindows.Demand(); num1 = (((buttons | icon) | defaultButton) | options); ptr1 = IntPtr.Zero; if ((options & 2228224) == 0) { if (owner == null) ptr1 = UnsafeNativeMethods.GetActiveWindow(); else ptr1 = owner.Handle; } Application.BeginModalMessageLoop(); result1 = MessageBox.Win32ToDialogResult(SafeNativeMethods.MessageBox(new HandleRef(owner, ptr1), text, caption, num1)); Application.EndModalMessageLoop(); return result1; The value of 2228224 corresponds to MessageBoxOptions.DefaultDesktopOnly | MessageBoxOptions.ServiceNotification. The interesting thing here is that the owner parameter is always ignored since owner must be null when options contains the above flags. If owner is not null, the handle is never retrieved because options cannot also contain the above flags and therefore ptr1 remains as IntPtr.Zero. The other interesting thing is the BeginModalMessageLoop/EndModalMessageLoop block. It appears as though this disables all windows in the current thread, although I haven't looked at this too deeply, and this further implies that the owner parameter plays no part in establishing modality. Does anyone have any thoughts on this, particularly with reference to the fact that the BeginModalMessageLoop/EndModalMessageLoop block appears to be causing severe problems for my non-modal windows? A single call to the Win32 MessageBox function with a correctly specified owner window does not exhibit the same problems. TIA. -- Kevin Westhead Tag: Share a connection Tag: 61859

    - PropertyGrid customization Hi, I'm in the process of customizing the PropertyGrid for an application. I've written several TypeConverters and a few editors to display and process data within the grid. What I haven't been able to do yet is have the editor control receive the mouse input from another window. For example, I have a CAD app and I want modify a line entity. I select the entity and its properties are displayed in the PropertyGrid. I select the beginning coordinate field in the PropertyGridwant to modify the coordinate of the beginning point by selecting the location in the graphics window. Is this possible, or do I just need to create my own custom version of the PropertyGrid?? What I would ideally like to do is embed an existing custom control inside the PropertyGrid.

    - Form Scrolling I have scrolling in my app. When I click the arrows of the scroll bar or click inside the scroll bar the app scrolls -- but when I drag the scroll box (that part in the middle) the app does not scroll until after I release the mouse button.

    - Custom painting in TextBox Hello I have a new class which inherits from TextBox and implements a numeric textbox which have to allow the user to input signed numbers. The control of key input is OK. The problem is how to implement the display of the sign character. I am planning to enabled this feature by allowing the pressing of plus and minus keys (+ and -). When the user hits the minus key, the negative sign appears at the left side of the number; when he hits the plus key, no sign is shown in the textbox. This means that changing the left margin of the textbox is not enough to make this feature work because the textbox's default alignment is at the right side, and, in addition, the textbox must allows the programmer to change the text's alignment. I do not want to include the negative sign character in the text because of the lot of code I will have to write in order to control user key hitting. I am thinking about just painting the negative sign character at the left side of the text, without including it in the text, by handling some paint event. Does somebody knows some guidelines on how can I do this? Celio C Jr Tag: Share a connection Tag: 61835

    - System.Windows.Forms.MdiClient+ControlCollection not serializable. Scenario: --------- I have an Explorer style application. The app hosts other win forms by making them MDI children, removing border / control box / minimize / maximize, and setting the form's Dock property to Fill. I have recently upgraded my application in the following way: ------------------------------------------------------------- The MDI child forms are now contained within separate dynmically loaded assemblies. My host application creates a new application domain to load the assemblies into. A new instance of the child form is created within the context of the new application domain, then my host application communicates with that object via Remoting (cross AppDomains). Problem: --------- I can no longer set the MDI Child form's MdiParent property to my host app because my host app's ControlCollection is not serializable, and I get a SerializationException thrown. I either need to: - Find a way to set my remote MDI child's "MdiParent" property, or - Use the Win32 Api to create the child form as an MDI Child without adding it to my host application's MdiChildren collection. I don't really know how to do this, and am not sure it is even possible when using WinForms. Any suggestions? Trevor Germain, CET, MCP i-Gen Solutions, Inc. Tag: Share a connection Tag: 61830

    - How can I capture rows changing in datagrid (winforms) when arrow up/down is pressed? I update a form with labels and text boxes when the user clicks on the rowheader of my winforms datagrid. I notice that the user can move to a new row using the arrow up/down keys. I currently update the form using the click event of the datagrid. How can I update the form when the user moves to a new row using the arrow keys? In other words, I need to capture the arrow keys when the datagrid is active or when a new row is selected. BTW, I am using C#, however, if a VB.Net developer has a solution, please reply. I can always convert the code. Tag: Share a connection Tag: 61758

    - IDisposable, using(), RAII and structs [Discussion] Last night I had several thought about RAII and want to discuss a bit. Why doesn't CSharp support destructors in structs? Wouldn't that make RAII possible like in C++? When the struct goes out of scope, the dtor could be immediately be called (no GC needed). For that, you don't have to declare the whole File class as a struct (which would be not good for performance when File has a lot of data-members). Instead creating a thin wrapper would be a good solution: public struct MyFile { File f; public MyFile(string p) { f=new File(p); } ~MyFile() { f.Close(); } } That would do it. I have a second though which got through my mind. What about introducing an interface which is recognized by the compiler and forces usage of the using() statement. public interface IDisposableForce : IDisposable{} A second possibility could be declaring an attribute which marks IDisposable-implementing-classes wheather using() should be mandatory or at least suggested. enum WarnLevel {NoWarn,WarnLvl1,WarnLvl2,WarnLvl3,WarnLvl4,GenerateError}; class UsingAttribute{UsingAttribute(WarnLevel w){}} [Using(WarnLvl3)] // that means if warnlevel 3 or higher is set a warning is issued when this class is used without using()-statement public class MyFile : File { public class MyFile(string p) :base(p){} } What do you think? -- cody [Freeware, Games and Humor] www.deutronium.de.vu || www.deutronium.tk Tag: Share a connection Tag: 61739

    - [urgent] Message Box is non-modal in VB! Hi, In some situation, the message box can not be shown in modal mode. Please drop a DateTimePicker control on a Form (VB project), show a message box in the ValueChanged event, as below snippet. Now run the form and drop down the calendar, select a date to let the event fire, after the message box shown, we can still activate the form background. This happens whatever MsgBoxStyle is specified even as MsgBoxStyle.SystemModal. Private Sub DateTimePicker1_ValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged MsgBox("DateTimePicker1_ValueChanged", MsgBoxStyle.ApplicationModal) End Sub The same scenario could be reproduced in a C# project, but I could pass it if by specifying the Form as the owner of the message box, as below code. private void dateTimePicker1_ValueChanged(object sender, System.EventArgs e) { MessageBox.Show(this, "dateTimePicker1_ValueChanged"); } Is something wrong in the message box method in VB? -jason Tag: Share a connection Tag: 61721

    - Button.TextAlign bug? Hi, I'm using C# and VS.net 2003. When adding a button to a form using the designer, the default TextAlign value is always set to MiddleCenter (which is fine). However, if I change the font to be bold, the text is no longer center- aligned, it is always a bit off to the right, more or less depending on the string value. The TextAlign property is still MiddleCenter though. Is this a known bug? Thanks, Henrik Tag: Share a connection Tag: 61711

    - A From won't close (c#) Hello everyone, I have main application form (child of System.Windows.Forms.Form) that hosts quite a number of different visual components. Some time after working with those components, the form refuses to be closed - I click menu item that invokes Form.Close() method, I click 'close' icon on the caption of the window (form) - nothing happens. No event comes to Form_Closing(Object, CancelEventArgs) method either. I'm at a loss how to even start debugging this situation and I would appreciate any suggestions.

    - How to force window to Maximize Hi, I would like to force my application to maximize when it is launched. I have tried this by setting the WindowState in the designer at runtime, and have also tried executing WindowState = FormWindowState.Normal The form does open maximized but it does not correctly maximize to the Windows taskbar...the bottom of the form is lost under the taskbar. If I use the form control menu to set the form to normal and then back to maximized, it correctly fits into the available desktop area, only going up to the top of the taskbar. Any ideas why??? Also I want to stop the user setting the window state to normal - I either want it maximized or minimized, but never normal. If the user double-clicks the Window title it does set the window state to normal. Is there an easy way to prevent this from happening??? Many thanks. Tag: Share a connection Tag: 61704

    - Check for illegal char in DataGridTextBoxColumn Hi all, need some help in taking the right approach to solve this problem. I have a DataGrid bound to a DataTable. I need the user to enter only numerical values and decimal. I did override the ProcessCmdKey of DataGrid. I'm capturing Enter, Tab, directinal and other keys. If the user enters an invalid key, I need to prompt him. But, for this I'll need to map all the other keys to be invalid in my code. Is there any other slick way of doing this. Code attached. protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { const int WM_KEYDOWN = 0x100; const int WM_SYSKEYDOWN = 0x104; int rowNum = dGInput.CurrentCell.RowNumber; int colNum = dGInput.CurrentCell.ColumnNumber; if ((colNum == 2) || (colNum == 5)) { if ((msg.Msg == WM_KEYDOWN) || (msg.Msg == WM_SYSKEYDOWN)) { switch(keyData) { case Keys.D0: case Keys.D1: case Keys.D2: case Keys.D3: case Keys.D4: case Keys.D5: case Keys.D6: case Keys.D7: case Keys.D8: case Keys.D9: case Keys.NumPad0: case Keys.NumPad1: case Keys.NumPad2: case Keys.NumPad3: case Keys.NumPad4: case Keys.NumPad5: case Keys.NumPad6: case Keys.NumPad7: case Keys.NumPad8: case Keys.NumPad9: case Keys.Decimal: case Keys.OemPeriod: break; case Keys.Back: break; case Keys.Down: case Keys.Up: case Keys.Left: case Keys.Right: case Keys.Enter: case Keys.Tab: UpdateDataGridCell(rowNum,colNum); break; default: MessageBox.Show("Invalid character","Error"); break; } } } Tag: Share a connection Tag: 61703

    - MSDN Sample - The ListManager's position must be equal to rowNum Hi All, I used DataGridComboBoxColumn from MSDN magazine ( http://msdn.microsoft.com/msdnmag/issues/03/08/DataGrids/default.aspx). Normally things work fine. but in the following cases I get an error 'The ListManager's position must be equal to rowNum'. ================================ 1) when I click on a comboboxcolumn cell 2) and scroll the datagrid 3) and click on another comboboxcolumn cell OR 1) navigate to a tabpage other than the one datagrid is on 2) and navigate back to datagrid tabpage 3) and click on a comboboxcolumn cell ================================ Good news is I made a change to the code and the problem went away. The bad news is I can't understand why! Just wonder if the experts here might be able to help? The change that I made to DataGridComboBoxColumn are 1) remove combobox.hide from datagrid_scroll event 2)add code in edit method to hide the combo when current cell is not visible (I'll attach both codes) I have trace output for the following sequence of action 1) click on datagridcombobox column cell at row 3 (index 2) 2) then click on datagridcombobox column cell at row 5 (index 4) 3)scroll one cell 4)then click on datagridcombobox column cell at row 6 (index 5) ==============TRACE OUTPUT ORIGINAL CODE====================raises the error Edit 2 Leave: column1 column1 SetColumnValueAtRow 2 column1 Edit 4 -------------I scroll now Edit 4 Leave: column1 column1 SetColumnValueAtRow 4 column1 Scroll -------------combo hidden is hidden now Leave: column1 column1 SetColumnValueAtRow 4 column1 Edit 4 <------things start to go wrong here? why is it entering edit 4...when it should be going to edit 5 Edit 5 Leave: column1 column1 SetColumnValueAtRow 4 column1 ===============TRACE OUTPUT MODIFIED CODE====================no errors raised here Edit 2 Leave: column1 column1 SetColumnValueAtRow 2 column1 Edit 4 -------------scroll Edit 4 Leave: column1 column1 SetColumnValueAtRow 4 column1 Scroll -------------combo stays Leave: column1 column1 SetColumnValueAtRow 4 column1 Edit 5 ================================== notice that things start to go a bit crazy in last 3-4 lines. The thing that seems to cause the error is Edit method being called in the first case for rowindex 4 and then rowindex5 immediately....unlike the second case.... It may not make much sense w/o the code so I attach both cases with the mail. ====================ORIGINAL CODE=================== // Derive class from DataGridTextBoxColumn public class DataGridComboBoxColumn : DataGridTextBoxColumn { // Hosted ComboBox control private ComboBox comboBox; private CurrencyManager cm; private int iCurrentRow; // Constructor - create combobox, register selection change event handler, // register lose focus event handler public DataGridComboBoxColumn() { this.cm = null; // Create ComboBox and force DropDownList style this.comboBox = new ComboBox(); this.comboBox.DropDownStyle = ComboBoxStyle.DropDownList; // Add event handler for notification of when ComboBox loses focus this.comboBox.Leave += new EventHandler(comboBox_Leave); } // Property to provide access to ComboBox public ComboBox ComboBox { get { return comboBox; } } // On edit, add scroll event handler, and display combo box protected override void Edit(System.Windows.Forms.CurrencyManager source, int rowNum, System.Drawing.Rectangle bounds, bool readOnly, string instantText, bool cellIsVisible) { Debug.WriteLine(String.Format("Edit {0}", rowNum)); base.Edit(source, rowNum, bounds, readOnly, instantText, cellIsVisible); if (!readOnly && cellIsVisible) { // Save current row in the datagrid and currency manager associated with // the data source for the datagrid this.iCurrentRow = rowNum; this.cm = source; // Add event handler for datagrid scroll notification this.DataGridTableStyle.DataGrid.Scroll += new EventHandler(DataGrid_Scroll); // Site the combo box control within the bounds of the current cell this.comboBox.Parent = this.TextBox.Parent; Rectangle rect = this.DataGridTableStyle.DataGrid.GetCurrentCellBounds(); this.comboBox.Location = rect.Location; this.comboBox.Size = new Size(this.TextBox.Size.Width, this.comboBox.Size.Height); // Set combo box selection to given text this.comboBox.SelectedIndex = this.comboBox.FindStringExact(this.TextBox.Text); // Make the ComboBox visible and place on top text box control this.comboBox.Show(); this.comboBox.BringToFront(); this.comboBox.Focus(); } // else // { // this.comboBox.Hide(); // } } // Given a row, get the value member associated with a row.

    - typed dataset on inherited form There is obviously a bug in VS.NET 2003: Steps to reproduce: 1.) Create typed DataSet with one unique key. 2.) Make WinForm and place a (visual) instance of the typed DataSet on it. 3.) Create an inherited form (base on the first form). 4.) Place any control (button,...) on the second form. When running the test-app, an exception is thrown. (System.ArgumentException: Cannot add primary key constraint since primary key is already set for the table.) Reason: VS generates code in the inherited form for the dataset, which will add the same constraint again to the dataset. I found a thread, reporting this topic: http://groups.google.at/groups?threadm=009801c31794% 24f74a5bb0%242f01280a%40phx.gbl This thread is from May 03 and it says, that this is a known bug and a KB-article regarding this issue is going to be published.

This is my code IEnumerator ie = Panel.Controls.GetEnumerator(); while(ie.MoveNext()) { CheckBox chk = new CheckBox(); chk = (CheckBox)ie.Current; if(chk.checked) { Panel.Controls.Remove(chk); } } And when I comment the condition, it removes only some elements, for example, if the panel has 27 elements, it removes 10 and it leaves 17. What's wrong?? Regards Tag: Share a connection Tag: 61675

    - Troubles with TreeViews I am experiencing strange behavior from the Standard Windows Forms TreeView control. My application retrieves a dataset from a Web-Service. If the download was sucessful, I call the Dataset.WriteXml() method to persist the dataset to the local disk. The next time the app runs, I check to see if the Xml file exists, and if it does, I call ReadXml() instead of going to the webservice. (The data doesn't change often). From the dataset, I generate a six-level treeview. Everything works fine the first time, until I choose to refresh the dataset, and re-generate the treeview. The tree goes blank, except for a single plus/minus image. When I click on the 'node', it seems to expand, but no data is being displayed. I am doing the following when I refresh the data: 1. Clear the contents of the dataset 2. Retrieve the data again from the web-service 3. Remove all nodes from the tree-view 4. Re-build all nodes from the dataset This process works great when I first run the program, but when I try to refresh the dataset while it is running, it gives me grief. Anyone have any ideas? Sorry for the long winded explanation. Any help would be appreciated. ........./mike Tag: Share a connection Tag: 61674

    - ListView Paint I got no answer before, so I'm reposting. I have built a listview which I change the Size and View properties at run time. The imagelist associated to SmallList and LargeList properties is the same. The problem is that it works great when View = LargeIcons, but it shows blank/no icons at all when I set View to anything else. But, minimizing the window OR sorting the listview solves the problem. Seeing that I don't want to do any of these 2 things as a workaround, and listview.Refresh() doesnt work at all, does anybody have any suggestion on how to refresh the listview? I have read something about Listview not invoking the Paint event. Thanks! Tag: Share a connection Tag: 61673

    - How does a MDIParent position its children We are trying to control the cascading of mdi children as they open up. We can do this with some success in the mdi child but it seems the parent overrides what we do. What does a mdiparent do in regards to positioning its child forms? Is there a way prior to or on the call to show to tell the mdiparent where to position the child? Tag: Share a connection Tag: 61655

    - Make Container UserControl force controls to be added to a child container control Hi, I'm writing a container usercontrol. It consists of two panels. The first panel is designed to act as a titlebar for the usercontrol. I want the second panel to become the place where other controls are contained when dropped on to it from a form designer (so they can never be positioned on top of the title). Is there any way of fooling the windows forms designer into adding contained controls into the second panel, instead of the usercontrol itself? I appreciate any help anyone can give me. Thanks, Trev.

Connection to a database? Just pass a reference to the connection
object to the other form.
