 - No touch deployment and XP Themes Hi. How do I adopt XP-theme together with no touch deployment? I am using no touch deployment of a windows application (framework 1.1). The problem is when deploying the application through no touch the visual style does not adopt XP-themes. I am using... Application.EnableVisualStyles(); Application.DoEvents(); ... but i do not seems to work. I have also tried to use a Manifest file, but i do not think it is sent to the client computer. Maybe I am doing something wrong!?! Can anybody please help! Thanks in advanced. Tag: Unwanted Focus in TabControl Tag: 61919

 - Focus form after use popup menu in notifyicon Hello, I have form with notifyIcon and popup menu for notifyIcon. I modified Close event - I hide form instead close. When I clik to icon in systray, form shows. But when I selected item from popup menu over notifyIcon, form shows too - but I don't show it, only run any code. How do I it?

 - Textbox-level validation Folks, I have a C# WinForms app, and I am doing some validation of text boxes and their contents. So far, I've used the TextBox1_Leave event - if the focus goes away from the textbox, I check for certain conditions (not empty, valid entry etc.). This works okay so far - but in some cases, I'd like to skip that validation, e.g. when the user clicks on the "Cancel" button. But how can I "foresee" that the user has clicked the Cancel button, inside my TextBox1_Leave event?? In Delphi, we used to be able to inspect a property "ActiveControl" which was set to the button that had been clicked - based on that info, I was able to determine whether or not I wanted to apply my validation. I don't seem to find anything similar in C# / .NET - I do have an "ActiveControl" property, but that is still set to my text box, as long as I'm still on it..... Any way to achieve what I'm trying to do without major kludges?? Marc ================================================================ Marc Scheuner May The Source Be With You!

 - Scope of form variables... This may sound like a dumb question, but I am hoping someone might comment on it.... Consider the following method (assuming that Form1 is a class derived from System.Windows.Forms.Form) : private void MyMethod() { int i = 1; Form1 myForm = new Form1(); myForm.Show(); } Both of the variables, i and myForm, are local variables that should go out of scope when the method is finished executing. But the myForm variable continues to live on. Is this correct? Why is the scope of form variables different than the scope of other types? Tag: Unwanted Focus in TabControl Tag: 61889

 - Main Form Unresponsive I'm building a custom install program that allows the user to select which assemblies get installed. In creating the prototype I am encountering a situation where the main form will not accept user input after the installation is complete. In my form, pressing the 'Install' button runs the following method: public override bool Install() { IDictionary savedState = new Hashtable(); System.Configuration.Install.AssemblyInstaller ai = new System.Configuration.Install.AssemblyInstaller(); try { ai.Path = "testassembly.dll"; ai.UseNewContext = true; ai.Install(savedState); ai.Commit(savedState); ai.Dispose(); return true; } catch (Exception e) { return false; } } My trivial installer class is the only class in the "testassembly.dll" named above: [RunInstaller(true)] public class Installer1 : System.Configuration.Install.Installer { public Installer1() { } public override void Install(IDictionary stateSaver) { base.Install (stateSaver); MessageBox.Show("Installing", "TestAssembly"); } public override void Uninstall(IDictionary savedState) { base.Uninstall (savedState); MessageBox.Show("Installing", "TestAssembly"); } } After the install MessageBox is dismissed, the main form gets updated (progress bar goes away and a 'Done' button is made visible) correctly, but when I try to either click the 'Done' button to exit the app, or close the form, nothing happens. If I remove the MessageBox from the installer class, then everything works correctly and I can exit the app, so I assume that there is some sort of forms or event loop issue going on, but I have not been able to figure it out. Anyone have any ideas? Matt Tag: Unwanted Focus in TabControl Tag: 61883

 - 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: Unwanted Focus in TabControl 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 ?

 - 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: Unwanted Focus in TabControl 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.

 - 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: Unwanted Focus in TabControl 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.

 - 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: Unwanted Focus in TabControl Tag: 61739

The table is empty and that brings me to my next chalenge: How can I get the info in the table in the dataset to go in an empty SQL table? Is there a short way like the FILL method to get data into the dataset or do I have to read each datarow in the table and write it one at the time to the database? rg, Eric Tag: Unwanted Focus in TabControl Tag: 61724

 - [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: Unwanted Focus in TabControl 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: Unwanted Focus in TabControl 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: Unwanted Focus in TabControl 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: Unwanted Focus in TabControl 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....

 - 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. But I could not find anything! :( Are there any solutions to this problem yet??? Thanks for any answer!! Thomas Tag: Unwanted Focus in TabControl Tag: 61696

 - What framework for MDI applications is recommended? I came from a C++ MFC background to Windows Forms .NET programming. Windows apps are best written on top of a framework of some kind.

 - Collection Hi again I've been trying to erase an element from a Collection, but when I do this I get this exception Object reference not set to an instance of an object. 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: Unwanted Focus in TabControl Tag: 61675

Hi,
When I'm using the SelectedIndex property to
programmatically change the current TabPage of a
TabControl (or controlling it by DataBinding), the
corresponding TabPage "steals" Focus. Does anybody know a
simple way to avoid this?

Thank you in advance!
