 - Problem with windows datagrid in .net 1.1 with tablestyle. hello All, i have following problem with datagrid, I have windows datagrid. I have one custom tablestyle applied to it.I have delete funtionality on this datagrid that when user select row by clicking on the rowheader and pressing delete on keyboard. I have confirmation over delete key press to ask user whether to delete or not row. Now the problem is when i select any row and press delete button i can see the popup and if user clcks "No" here i am rebinding the grid with same datasource but after rebinding if i click on the next row the content in the first column of previously selected row for which we have done delete get vanished. I have 2 observations 1) If we have datagrid with all above functionality but without tablestyle the problem never happen. 2) As we add tablestyle into it problem will be there. //C# code For without tablestyle. private void Form1_Load(object sender, System.EventArgs e) { for(int i=0;i<2;i++) { if(i==0) { DataColumn dc=new DataColumn(); dc.Caption="Name"; dc.ColumnName="Name"; dc.MaxLength=50; dt.Columns.Add(dc); } else { DataColumn dc=new DataColumn(); dc.Caption="Age"; dc.ColumnName="Age"; dc.MaxLength=50; dt.Columns.Add(dc); } } createRow(); //myGrid1.TableStyles.Add(AddTableStyle()); myGrid1.DataSource=dt; } private void createRow() { DataRow dr=dt.NewRow(); dr[0]="Ashish"; dr[1]="25"; dt.Rows.Add(dr); DataRow dr1=dt.NewRow(); dr1[0]="Tee"; dr1[1]="25"; dt.Rows.Add(dr1); DataRow dr2=dt.NewRow(); dr2[0]="Helllo"; dr2[1]="25"; dt.Rows.Add(dr2); } private void myGrid1_RowDelete() { MessageBox.Show("You can't delete this row"); myGrid1.DataSource=null; myGrid1.DataSource=dt; } private DataGridTableStyle AddTableStyle() { DataGridTableStyle ts=new DataGridTableStyle(); ts.MappingName=dt.TableName.ToString(); for(int y=0;y<dt.Columns.Count;y++) { DataGridTextBoxColumn col=new DataGridTextBoxColumn(); col.MappingName = dt.Columns[y].ColumnName; col.HeaderText = dt.Columns[y].ColumnName; col.Width = 150; col.TextBox.MaxLength=50; ts.GridColumnStyles.Add(col); } return ts;; } //C# code with tablestyle private void Form1_Load(object sender, System.EventArgs e) { for(int i=0;i<2;i++) { if(i==0) { DataColumn dc=new DataColumn(); dc.Caption="Name"; dc.ColumnName="Name"; dc.MaxLength=50; dt.Columns.Add(dc); } else { DataColumn dc=new DataColumn(); dc.Caption="Age"; dc.ColumnName="Age"; dc.MaxLength=50; dt.Columns.Add(dc); } } createRow(); myGrid1.TableStyles.Add(AddTableStyle()); myGrid1.DataSource=dt; } private void createRow() { DataRow dr=dt.NewRow(); dr[0]="Ashish"; dr[1]="25"; dt.Rows.Add(dr); DataRow dr1=dt.NewRow(); dr1[0]="Tee"; dr1[1]="25"; dt.Rows.Add(dr1); DataRow dr2=dt.NewRow(); dr2[0]="Helllo"; dr2[1]="25"; dt.Rows.Add(dr2); } private void myGrid1_RowDelete() { MessageBox.Show("You can't delete this row"); myGrid1.DataSource=null; myGrid1.DataSource=dt; } private DataGridTableStyle AddTableStyle() { DataGridTableStyle ts=new DataGridTableStyle(); ts.MappingName=dt.TableName.ToString(); for(int y=0;y<dt.Columns.Count;y++) { DataGridTextBoxColumn col=new DataGridTextBoxColumn(); col.MappingName = dt.Columns[y].ColumnName; col.HeaderText = dt.Columns[y].ColumnName; col.Width = 150; col.TextBox.MaxLength=50; ts.GridColumnStyles.Add(col); } return ts;; } How can i i prevent value to be vanished in datagrid with tablestyle.

 - DataGridView column sorting glyph not shown Hello, I am using a DatGridView in virtual mode and unbound data where i listen for CellValueNeeded events to fill the grid with data. I also want to sort the data by pressing on the columns which is why i listen to ColumnHeaderMouseClick as well. It works fine, but the problem is that the sorting glyph (i.e. the sorting order triangle image) is not visible on the column header if the column size is too small. I have tried all the AutoFill options available for the column size/width but none of them seem to be working. The sorting glyph "length" is simply ignored and column width is not adapted to include to glyph (i have to manually resize the column size to see the glyph). Is there any automatic way of handling this or do i have to calculate the column width manually by taking into consern the column header text length, font size and so on?

 - TypeConverter for object type Properties I have a property with a member of type object. I am showing the value of this property in a PropertyGrid but depending on the type of the object I want to use the correspondant TypeConverter. Here is an example of what I mean: public byte[] Test { get { return new byte[100]; } } public object Test2 { get { return new byte[100]; } } If I have both properties in a property grid, Test will be shown as an expandable item with the text "Byte[] Array".. if I expand the item I will be able to see all of the elements in the array. However, Test2 will only show the text "System.Byte[]" and I will have no way of reading the elements of the array. Of course the property of type object will not always contain a byte[]. How can I provide the standard functionality for each type? Thanks Tag: MDI and Form.TopMost Problem Tag: 116328

 - Cascade non-MDI Forms I have code that cascades multiple forms that belong to my application. They are not MDI so my understanding is that the accepted method is to call CascadeWindows in user32.dll and use the desktop as the owner window. The problem is that it's un maximizing all other windows regardless of whether or not I pass their window handles to the method. Is there another way to do the cascade that doesn't have this side effect? I know I could just change all the locations. But it's the algorithm for determining the window size and z-order that I'm not yet comfortable re-writing. Any help is appreciated. Thanks, Brian Tag: MDI and Form.TopMost Problem Tag: 116324

 - Controls in TablelayoutPanel not getting arranged properly Hi, I am programmatically creating a TableLayout panel with 8 columns and 21 rows . Within the cell I am placing some labels and checkboxes . Then I dynamically add more rows , by calling my function UpdateTable( ). private TableLayoutPanel tb = new TableLayoutPanel (). private void UpdateTable( ) { tb.SuspendLayout() ; tb.GrowStyle = TableLayoutPanelGrowStyle.AddRows; // assume LastRowCount = 21 , as I have added 21 rows earlier // hence I increment LastRowCount in the for loop initialization for( int i = LastRowCount+1 ; i< 20 ; i++ tb.RowStyles.Add( myRowStyle ); tb.ResumeLayout(false ); } Strangely enough the following things happen 1) Calling UpdateTable() for the first time - Only one row gets added ; 2) Calling UpdateTable () for the second time - The checkboxes are getting redrawn in DIFFERENT positions ... which is not desired . For the second one, I think pending layouts are getting performed intenally by the layout engine ... Can anyone help me in getting answers to these problems .

 - Can't get ComboBox to show that it has focus I have a WinForm with many text boxes and several combo boxes. I also have a toolstrip with cut, copy, and paste icons. When a user clicks one of the buttons (cut/copy/paste), I want to get the current active control and if it is a textbox or a combobox, to then copy the selected text to the clipboard (or do the appropriate option based on the button). I can get all of this to work just fine with the textboxes. To figure out the active control, I am using the GetFocus() pointer from "user32.dll". This is the only way I could find to do what I needed to do. Below is an example of how my code looks. [DllImport("user32.dll")] public static extern IntPtr GetFocus(); private void btnCopy_Click(object sender, EventArgs e) { FocusControl = Control.FromHandle(GetFocus()); if (FocusControl != null) { if (FocusControl.GetType().ToString() == "System.Windows.Forms.TextBox") { TextBox myTextBox = (TextBox)FocusControl; if (!string.IsNullOrEmpty(myTextBox.SelectedText)) { Clipboard.SetText(myTextBox.SelectedText); } } else if (FocusControl.GetType().ToString() == "System.Windows.Forms.ComboBox") { ComboBox myComboBox = (ComboBox)FocusControl; Clipboard.SetText(myComboBox.SelectedText); } } } This works great for textboxes, but if the focus is on a combobox, the FocusControl object is null, so it doesn't fall into the if statement. I've tried using the ActiveControl method, but couldn't figure out how to drill down to the actual control that had focus. All it gave me back was the control that the textbox was on, not the actual textbox control. I'm sure I could iterate through each child control, but I figured there had to be an easier way. Any help would be greatly appreciated. Tag: MDI and Form.TopMost Problem Tag: 116320

 - How to write IExtenderProvider control for .NET CF? Hi, I searched all over the net and I can't find no info how to do this, other then this post http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=158930&SiteID=1. I would like to rewrite this example http://msdn2.microsoft.com/en-us/library/system.componentmodel.iextenderprovider.aspx for Compact Framework, and I would like to do it VS2005 way. VS2005 suggests to use .xmta file which will produce *.PocketPC.asmmeta.dll file. The article I found also suggests to create yet another library where the designer would be. Does this mean that now instead of distributing two libraries (one for runtime one for design time) I have to distribute three (an extra *.PocketPC.asmmeta.dll)? I have a hard time to believe it.

 - Best practice for saving objects owned by objects Let's say that I have a class called Customer and a class called CustomerAddress. Now, further suppose that the Customer class has a property called _CustomerAddresses, which is List(Of CustomerAddress). Now, there's a form to edit a Customer, on which the user can click on a SAVE button to save changes, or on a CANCEL button to cancel any changes that they have made. In addition, on the Customer form, the user can make changes to the different CustomerAddress's that belong to the Customer (i.e. add, edit, remove). A separate form is used for adding or editing a CustomerAddress. For example, the user could select a CustomerAddress, in a grid, and then click on an EDIT button, at which point the Customer Address form is shown modally. On the Customer Address form, the user can also click on SAVE or CANCEL. Now, here's where the question comes in. The way that I am implementing this is that, if the user clicks on CANCEL for the Customer, any adds, edits, or deletes of CustomerAddress records associated with that Customer are disregarded/discarded. Is this the "usual" way to implement functionality like this? Tag: MDI and Form.TopMost Problem Tag: 116315

 - Problems with UNICODE Characters for superscript 4,5,6,7,8,9 Hi, We have an application that has its own character map. Everything is working fine until yesterday. We got a new requirement which was to add superscript numbers from 0-9. Numbers 1,2,3 are display correctly. The issue is the 0, 4-9. With those characters I got the square on my Rich Text Box. The funny thing is, if I copy/paste one of them from Windows Character Map, after that all character will work using our character map. The way I'm passing the characters from our C.M to the Rich Text Box is the follow: Clipboard.SetText(CType(sender, UIButton).Text, TextDataFormat.UnicodeText) and Me.m_CurrentRTB.Text = Clipboard.GetData(System.Windows.Forms.DataFormats.UnicodeText) Does anyone had this issue before?

 - Document.GetElementsByTagName(...) returns no elements I have C# .NET 2.0 code that behaves incorrectly only when run on one Windows Server 2003 (32 bit) machine with .NET 2.0 installed. And then, only the first time. And then, only when run from a CDrom. It will not fail on the local disk or network share. I have a WindowsForms application with a WebBrowser class on a form. In the DocumentCompleted event, I do... HtmlElementCollection divTags = webBrowser1.Document.GetElementsByTagName("div"); These documents are static docs loaded from the application directory. The document which has the DIV tag is loaded and the collection shows a count of zero the first time it is run on this machine from a CDrom. After that, it finds the DIV tag everytime. If I reboot, we are back to not finding it the first time. Right before the GetElementsByTagName() method, I dumped the Document.Text to the log file - indeed, there is the DIV tag. Any ideas?

 - WPF Data binding & Threading Dear reader, Im having a threading problem using WPF data binding on a custom dependency object with a clr object as data source and trying to update the data source from another execution context. The data source consists out of a simple class which implements the INotifyPropertyChanged interface. <code> // The clr object used as a data source. public class MyDataSource : INotifyPropertyChanged { private string _data; public MyDataSource(string info) { _data = data; } public string Data { get { return _data; } set { _data = value; this.NotifyPropertyChanged(value); } } private void NotifyPropertyChanged(string data) { if (this.PropertyChanged != null) { this.PropertyChanged(this, new PropertyChangedEventArgs(data)); } } public event PropertyChangedEventHandler PropertyChanged; } </code> The custom dependency object exposes one dependency property which I want to bind to the Data property of the data source. Below the code for illustration: <code> // the custom dependency object. public class MyCustomObject : DependencyObject { public static readonly DependencyProperty DataProperty = DependencyProperty.Register("DataProperty", typeof(String), typeof(MyCustomObject), new PropertyMetadata(String.Emoty, new PropertyChangedCallback(OnPropertyChanged))); public static void OnPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { MyCustomObject obj = (MyCustomObject) d; Console.WriteLine(String.Format("Property '{0}' changed; OldValue '{1}', NewValue '{2}'.", e.Property.Name, e.OldValue, e.NewValue)); } public MyCustomObject() { } public string Data { get { return (string)this.GetValue(DataProperty); } set { this.SetValue(DataProperty, value); } } } </code> And finally the binding definition: <code> MyDataSource dataSource = new MyDataSource("Hello World!"); MyCustomObject customObj = new MyCustomObject(); Binding binding = new Binding("Data"); binding.Mode = BindingMode.OneWay; binding.Source = dataSource; BindingOperations.SetBinding(customObj, MyCustomObject.DataProperty, binding); ... // Causes the dependency property to change. dataSource.Data = "Greetings World!"; </code> The above code works fine. But when I try to update the "dataSource" object from a WCF service callback (duplex mode) it doesn't update the dependency property. I think it as something to do with the execution context being different. Can anybody shed some light on this matter and explain me why this binding doesn't work this way and maybe come up with a solution. I'm running the above code within a console application (STA) compiled with the .NET Framework 3.5 version in Visual Studio 2008. Kind regards, Alex Koning.

 - Drag & Drop - multiple controls I've recently migrated from VB.NET to C# and have 3 questions about drag/drop differences between the two languages... Question 1) I'm tweaking a C# app (DotNet 2.0) to support file drag/drop. I have 2 textboxes with Browse lookups, but I realized some users prefer to drag drop files from folders on the desktop. The examples I've seen are for 1 drop location on the windows form. Are there any examples of implementing drag/drop for multiple controls? Question 2) Take a look at the following function header: private void txtFileToProcess_DragDrop(object sender, System.Windows.Forms.DragEventArgs e) { //my code here... } What ties this function as the handlerto the txtFileToPRocess control? Question 3) How do I add event handlers on the fly? This was trivial in VB.NET; you simply selected the control (in the dropdown), then the event (in an adjoining dropdown).

 - Popup window on top of another popup Hi guys, I have a grid editor, with cells (DevExpress). I have a custom cell edit, which contains two other edits. When I click the cell, I get the first popup edit. When I click the other controls contained in this popup, another window pops up. The problem is that the moment I click inside the second popup, the first one disappears, and as a consequence, the second one disappears too. Is there a way to keep the first popup visible, while the second one is editing? Thanks in advance, Cosmin Tag: MDI and Form.TopMost Problem Tag: 116296

 - DoEvents for a specific thread? Hi, I have a thread (not the main) in my app that draws GUI. It's a STA-thread, and it seems OK. Though I would like to process its message queue, like Application.DoEvents (for the main thread). It should have a message queue since it draws GUI. How do I "do a DoEvents" for a specific thread? regards Carl Tag: MDI and Form.TopMost Problem Tag: 116290

 - subscribing to events in controls in a separate window in another window ? < .NET 2.0, VS Studio 2005 Ent., Win XP Pro SPII, all .NET Frameworks from 1.0 to 3.5 installed > ... note : normally I do not cross-post, but I felt this scenario justified sending to both the controls and windowsforms groups ... Hi, 1. Main form creates other top-level winform windows at run-time (new window parent == null) from a pre-defined form template as : secondaryFormTemplate newSForm = new secondaryFormTemplate(); // set formborderstyle, set to topmost, toplevel, etc. newSForm.Show; 2. On each secondary winform you create there is treeview (which has public accessor); you subscribe to the After_Select event of each Treeview IN THE MAIN FORM with the same event handler in the main form like so : newSForm.myTreeView.After_Select += new System.Windows.Forms.TreeViewEventHandler(secondaryTVHitHandler); 3. so the handler for all secondary treeview selection in the main form looks something like this : private void secondaryTVHitHandler(object sender TreeViewEventArgs e) { // do whatever, get the node from e.Node, etc. } This compiles okay, seems to work okay most of the time, but once in a while it appears that node selections in some of the secondary windows are not reported to the subscriber in the main form. So, I switched back to the more "classic" paradigm of having the secondary form template implement an After_Select event which raises a public event, which I then subscribe to in the main Form. Intermittent problems of some selection events went away. My question is : were the glitches I observed using the first technique possibly a result of threading problems involving separate independent top-level winforms ? Another hypothesis : the .net TreeView (now, like me, so long in the tooth :) is, as we all know, a wrapper around a COM control ... issues related to COM ? My sense is that it is "best practice" to have objects raise public events from their own internal private events, rather than have "alien objects" subscribe directly to events of objects, but in the case where the secondary objects (winforms in this case) are being created at run-time by a "master object" it is "tempting" to just subscribe to their events there.

Where can I find a list of the sequence of events that a vb.net form goes through... when the executable is first run? (Before the user has moved/clicked/typed anything).

 - Overriding dataset connection Hi I have a windows form app with one master table and several details (grids). As I am filling both the master and details using vs 2005 generated dataset and data adapters, there are multiple connection open/close during the whole operation (one connection open/close per adapter fill). Is there a way to override the vs generated connection management code to open the connection only once at start, do all fills and then close the connection at the end, to speed up the whole fill process? As dumping the vs 2008 dataset altogether will involve too much code writing, I am reluctant to let go of it and would prefer to only override the connection management if I can. Many Thanks Regards Tag: MDI and Form.TopMost Problem Tag: 116272

 - Problem Drawing in a ListBox Subclass Good afternoon, everyone. I've subclassed ListBox to draw an icon next to each line, and it works! Except for one thing... when drawing items, it seems that SelectedItems and SelectedIndices is not perfectly current. This means that if I use it to draw, in some cases I may draw an item highlighted when it shouldn't be, or vice-versa. This mostly happens when dragging to select multiple entries. My temporary solution is to force a Refresh after every SelectionChanged event, but this makes the list less responsive. Basically, I'd like it to paint just like a normal listbox. So far I've only used this with an extended multi-select list box. This is the relevant code in my subclass: // Constructor: ... DrawMode = DrawMode.OwnerDrawFixed; DrawItem += Draw; SelectedIndexChanged += SelectionChange; ... // Handlers: protected void Draw(object sender, DrawItemEventArgs args) { args.DrawBackground(); int row = args.Index; Graphics graphics = args.Graphics; Rectangle bounds = args.Bounds; if (row != -1) { object item = Items[row]; // Draw the icon, if any Image icon = GetIconForItem(item); if (icon != null) graphics.DrawImage(icon, bounds.Location); // Draw the text, if any string text = item.ToString(); if (text.Length > 0) { int textHeight = Font.Height; int offSet = (ItemHeight - textHeight) >> 1; Brush brush = new SolidBrush(SelectedItems.Contains(item) ? SystemColors.HighlightText : ForeColor); graphics.DrawString(text, Font, brush, ICON_SIZE + 1.0F, (float)(bounds.Top + offSet)); } } args.DrawFocusRectangle(); return; } protected void SelectionChange(object sender, EventArgs args) { Refresh(); return; } Any ideas from the Windows Forms gurus?

 - .NET Mass Downloader Version 1.2 Released We have improved the proxy support and added more samples of usage for 2005 , 2008 and Visual Studio Express Editions. You can get your copy from http://www.codeplex.com/netmassdownloader .NET Mass Downloader Welcome to the .NET Mass Downloader project. While it's great that Microsoft has released the .NET Reference Source Code, you can only get it one file at a time while you're debugging. If you'd like to batch download it for reading or to populate the cache, you'd have to write a program that instantiated and called each method in the Framework Class Library. Fortunately, .NET Mass Downloader comes to the rescue! Using .NET Mass Downloader Open a command or PowerShell prompt and navigate to where you extracted the current release. The tool itself is NetMassDownloader.exe and when run without parameters shows the following help screen: .Net Mass Downloader 1.0.0.0 - (c) 2008 by Kerem Kusmezer, John Robbins Batch download the Microsoft .NET Reference Source code. Usage: NetMassDownloader [-file <file>] [-directory <directory] [-output <directory>] [-vsver <version>] [-force] [-nologo] [-verbose] [-?] -file - Download an individual file's PDB and source code. You can specify multiple file parameters. (Short -f). -directory - Download all the found PDB and source code for all files in the specified directory. You can specify multiple directory parameters (Short -d). -output - The output directory for PDB and source files. The default directory is the cache directory set in Visual Studio 2008. By using the cache directory, you'll have the PDB and source files available to Visual Studio 2008. However, to use the .NET Reference Source Code with VS 2005, use the - output switch and in the Options dialog, Debugging, Symbols property page, add the specified output directory to the "Symbol file (.pdb) locations." Also, add the directory to the Solution Properties, Common Properties, Debug Source Files, Directories containing source code location. The Visual Studio 2005 debugger will automatically load the source code. (Short -o) -vsver - The Visual Studio version number to use for finding the cache directory. The default is Visual Studio 2008, but if you want to use the cache directory for Visual Studio 2005, you would pass '-vsver 8.0' (without quotes) (Short -vs) -force - If specified, forces the downloading the PDB files into the symbol server. When downloading to a symbol server if the PDB exists, it's not downloaded. Using the -output switch will always download and process the PDB. (Short -fo) -nologo - Don't show the logo information. (Short -n) -verbose - Do verbose output. May be worth turning on as the downloading source code can take a long time. (Short -v) -? - This help message. The only required arguments are -file or -directory, both of which can be specified as many times as you'd like. When you specify a directory, only the .DLL and .EXE files from that directory will be processed. If you wanted to download all the source code from binaries in the .NET 2.0 32-bit and 64-bit directories, the command line you'd pass is: -d C:\Windows\Microsoft.NET\Framework\v2.0.50727 -d C:\Windows \Microsoft.NET\Framework64\v2.0.50727. The main purpose of Net Mass Downloader is to populate the source code download cache for debugging, the default download location is the cache you specified to Visual Studio 2008. The -vsver switch to account for future Visual Studio versions so Mass Downloader could work with future CTPs and versions. While it's great to see the .NET Reference Source Code in Visual Studio 2008, there are a lot of developers out there who can't upgrade yet, but would love to be able to debug into the .NET Reference Source Code. If you specify the -output parameter, the PDB and .NET Reference Source Code will be written to the specified directory. In Visual Studio 2005, place that directory in the Options dialog, Debugging, Symbols property page. In the "Symbol file (.pdb) locations" list box as the first item. Also in the Options dialog, Debugging, General property page, uncheck "Require source files to exactly match the original version." Finally, in each Visual Studio 2005 project go into the solution property pages, Common Properties, Debugging Source Files, and in the "Directories containing source code" add the output directory to the top of the list. That's enough for Visual Studio 2005 to debug into the .NET Reference Source Code. When you first run Net Mass Downloader, you will be prompted with the current EULA for accessing the source code. If you don't agree with the Microsoft EULA, clicking the Decline button will not download the source code. The code download includes a detailed documentation about whole steps required to use it with VS2005 If none of the files can be downloaded please download and install the rtm version of the RTM Version of the .NET Framework 3.5 According to the Shawns Blog The Following Dll Are Enabled For Now: Mscorlib.DLL System.DLL System.Data.DLL System.Drawing.DLL System.Web.DLL System.Web.Extensions.DLL System.Windows.Forms.DLL System.XML.DLL WPF (UIAutomation.dll, System.Windows.DLL, System.Printing.DLL, System.Speech.DLL, WindowsBase.DLL, WindowsFormsIntegration.DLL, Presentation.dll, some others) Microsoft.VisualBasic.DLL But our framework supports additional versions without update if microsoft doesn't change the download engine. The original framework anouncement can be found here: Shawns Announcement Acknowledgements Thanks to the Developer Division at Microsoft. First they released the .NET Reference Source Code, and second for allowing a couple of developers to have some fun and provide a utility for the community. Thank you for using .NET Mass Downloader.

Hello Group,

I am using .NET framework 2.0

I have a Windows Forms application. Using a menu item, I can set the TopMost
property of the MDI-Parrent form to true. Works fine.
I also have a "Windows menu". The menu has an entry for all open MDI windows
automatically (set MdiWindowListItem to the menu entry). Works fine as well.

Now the problem: if I have more than 9 windows open, only 9 windows are
displayed on the menu, plus an additional item "more windows..". Selecting
this item a window with a list box is displayed with all windows. The
problem: if the MDI parent window has TopMost set to true, this window is
displayed behind the MDI parent. This is especially a huge problem, if the
MDI parent window is maximized, because then I cannot move the MDI parent
window (the window in the background has the focus).

The only chance a user has in this case is to use the Task Manager to kill
the application --- which is never good for a commercial app.

Does anybody have an idea? What I would need is kind of a hook so I can do
something before the window with the list of windows is displayed.

Regards
Norbert Ruessmann
