    - Drag and drop file to list view in Vista I wrote a c# winforms application in .NET 1.1 which uses DragDrop functionality to allow a user to drag a file to a list view. It works fine in Windows XP, but in Windows Vista I get the "No drop" symbol. This holds true even when right clicking the application shortcut and choosing to run as Administrator. Any ideas what's preventing it from working in Windows Vista? Tag: There is a pure win32 control, I don't know how it's created, But I just wanna show it in a form control Tag: 108356

    - DataGrid / Context menu - HowTo Can someone direct me to a reference that describes how to create a context menu for a selected row in a datagrid? I have come across many threads regarding context menus and datagrids but they all seem to be how to modify the default behavior. I've gone through a couple of books and many threads but none of these seem to discuss creating a context menu for a given row. I did come across a thread that allowed me to create a menu for the entire grid but that even allows for a context menu outside of any rows. thanks for your help john Tag: There is a pure win32 control, I don't know how it's created, But I just wanna show it in a form control Tag: 108354

    - WebBrowser control - setting focus to a specific frame I have a WebBrowser control and its document contains a frameset with two frames: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd"> <HTML> <HEAD> <TITLE>Now Playing in iTAB</TITLE> </HEAD> <FRAMESET id="fs" frameborder="0" cols="25%, 75%"> <FRAME id="links" noresize="noresize" scrolling="no" src="lists.htm"> <FRAME id="main" noresize="noresize" src="np.htm"> </FRAMESET> </HTML> When I load the document I try to set focus to the main frame (so that if the user scrolls the scroll wheel this frame is scrolled, without having to click in it first) :- fullNP.Url = new Uri(htmlFolder + "frames.htm"); HtmlElement el = fullNP.Document.GetElementById("main"); if (el != null) el.Focus(); Unfortunately this doesnt work, the GetElementById returns null.

    - Cursor.Position I want to move the cursor in a MouseMove event callback. I'm using Cursor.Position to set the new mouse position. Unfortunately this seems to prevent the rest of the form from updating until I stop setting Cursor.Position (for example, I have a textbox and a progress bar that should update while the MouseMove event is being handled, but they don't update if I always set the Cursor.Position property.) I've tried calling the Win32 function SetCursorPos() directly, but that has the same effect. Is there something else I can do to make my form update? Thanks!

    - Modifications to DataGridView aren't reflected in Rows[] Good morning, I'm trying to update a DataSet based on data that has been modified in a DataGridView. The DataSet isn't binded to the DataGridView because of a couple conversions. (In this case, a time interval, or TimeSpan, is stored as number of milliseconds). I haven't found an elegant way to use the DataSource feature of the DataGridView and allow the millisecond timespan representation to be displayed as a user-friendly TimeSpan. To handle this disconnection, I'm simply creating a DataTable that contains the data the way I want things to appear in the DataGridView. This works well. My problem is when I want to save the changes back to the database. After the user makes a change to a cell and hits 'enter', the "New" row below is highlighted (indicating that the change was performed on the cell / row in question). Programatically, I read in the values from the DataGridView.Rows[] collection. The values I find are the original values from before the changes were made. Is there some magic property I'm missing or certain way to get the modified rows of a DataGridView? I have found nothing in the documentation that sheds any insight. Should I just hold a reference to a DataTable locally, bind THAT to the DataGridView, then just look at the table for changes? Why aren't the Rows[] giving me my changes?

    - Using lock to synchronize agent event with main UI thread... Hi all, We're doing an application in which a background agent is polling asynchronously for data and doing some work. When having new data it throws an event. A method is wired to the event, uses Invoke for updating selected datagrids etc. However, sometimes, the user is doing work (like executing a save method at the same time), and we want to postpone the redraw of the datagrids, or delay users input a little until updating is completed. All in all, we want to "syncronize" the events regarding updating and workm and what is shown. I may be misunderstanding the use of the lock statement, but basicaly the logic behind the code below is that if a lock statement is entered using the thelock object, other lock statments using the same object are put in "queue" and waits until the previous lock statement is exited. The code below is a form with two buttons. The first button starts a thread, simulating the agent throwing the event. The eventhandler uses Invoke to invoke Cross. The Cross method does some work (not a all near 15 seconds in real life, this is for show only). While entering and working (before the 15 seconds have past), the second button is pressed. I would expect the second buttons event handler to wait at the lock statement until the Cross method releases it, but I get this result: 15:31:58: Cross entering lock 15:31:58: Cross entered lock 15:31:59: Button2 entering lock 15:31:59: Button2 entered lock 15:32:00: Button2 exited lock 15:32:14: Cross exited lock My expected result would be: Cross entering lock Cross entered lock Cross exited lock Button2 entering lock Button2 entered lock Button2 exited lock or vice versa, regarding whoever comes first... but not mixed... After some testing I'm wondering if this is only valid as an idea. Is this the right way to do what I want? Am I misunderstanding the lock (is the lock only usable on the same code, not scattered locks in several methods? I have however seen property accessors that uses the same lock object, so...) PS. The while statement with sleep and DoEvents might also be wrong for simulating work while still being able to take input from the user. Maybe the example is done wrong, and the methods actually would be synchronized in a real situation? You're welcome to answer me in hard technical terms, I'm just fairly new to threaded windows programming... Thanks in advance! Christer public partial class Form1 : Form { private object thelock; public Form1() { thelock = new object(); InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { //Start worker thread ThreadStart ts = new ThreadStart(ThreadWork); Thread thread = new Thread(ts); thread.Start(); } private void button2_Click(object sender, EventArgs e) { Debug.Write(DateTime.Now.ToLongTimeString() + ": Button2 entering lock" + Environment.NewLine); lock (thelock) { Debug.Write(DateTime.Now.ToLongTimeString() + ": Button2 entered lock" + Environment.NewLine); MessageBox.Show("Button executed"); } Debug.Write(DateTime.Now.ToLongTimeString() + ": Button2 exited lock" + Environment.NewLine); } private void ThreadWork() { this.Invoke(new MethodInvoker(Cross)); } private void Cross() { Debug.Write(DateTime.Now.ToLongTimeString() + ": Cross entering lock" + Environment.NewLine); lock (thelock) { Debug.Write(DateTime.Now.ToLongTimeString() + ": Cross entered lock" + Environment.NewLine); DateTime seconds15 = DateTime.Now.AddSeconds(15); //Wait 15 seconds... while (DateTime.Now < seconds15) { Thread.Sleep(15); Application.DoEvents(); } MessageBox.Show("Cross executed"); } Debug.Write(DateTime.Now.ToLongTimeString() + ": Cross exited lock" + Environment.NewLine); } } Tag: There is a pure win32 control, I don't know how it's created, But I just wanna show it in a form control Tag: 108286

    - Bug or bad design in System.Windows.Form.Form Hi While developing a Windows forms application I encountered what I consider to be a bug or a design flaw: Consider to have 3 Forms namely A B and C. B is owned by A and C is owned by B. If we close A, all three forms should close which is exactly the design described in the class library reference on msdn. However, if the windows run in NON modal mode (i.e. not showed using ShowDialog(IWin32Window), closing A does call the OnFormClosing on A and on B but NOT on C. C gets closed without a way to check for unsaved data, because the FormClosing event doesn't get raised. If window B and C run in Modal mode (ShowDialog(IWin32Window)), C raises the FormClosingEvent (from within the OnFormClosing Method), but setting e.cancle = false will NOT prevent the window from closing, and even worse, the OnFormClosing method will run AFTER the window has already been disposed. Possible Reason: The invaluable resource .NET Reflector gave me some insight to the Implementation of the System.Windows.Forms.Form class. When a window closes, it calls OnFormClosing on all of its MdiChildren and Owned Windows. If e.cancle does not evaluate to false after these calls, the form gets Disposed. Dispose(bool disposing) calls Dispose on all owned forms, and thus it works recursively. But OnFormClosing does NOT. So when I call A.Close() it "asks" B to close, and if B does not set e.cancle, A disposes itself which in turn disposes B and C. So C gets Disposed without a prior call to OnFormClosing and no event rising. Shouldn't the (private) WMClose method in System.Windows.Forms.Form call some RECURSIVE method to check recursively for all owner relationships if the owned forms (in all levels of the owner relationship) can close? Possible workaround: (NOT tested yet) override the OnFormClosing method that it calls OnFormClosing for all owned forms recursively. This however will cause the OnFormClosing method to be called twice for all owned forms that are directly owned by the "root" form, because WMClose calls OnFormClosing on all its directly owned forms, and later calls this.OnFormClosing. The loop which calls OnFormClosing for all owned forms shouldn't be in WMClose but rather in OnFormClosing itself, thus be recursive. For MdiWindows this problem does not exist, because MdiCild Relations can only exist in one level, so for MdiChildren this problem does not exist. But when one closes the MdiParent of an MdiChild which owns some window X, OnFormClosing and the FormClosing Event will NOT be called for X. Has anyone ever encountered problems with this behavior as I did? And how did you solve the problem? I would consider this behavior either a bug or a design flaw!

    - notification windows a la Outlook Hi all, I've been recently struggling to get to the bottom of this, but can't find the proper way to do this. I have a notification window, which may appear on screen when certain events are received. Currently the notes are created and displayed on the main form's gui thread. It works ok, until you go into 'modal' mode. That is, if there are a modal form and the note simultaneously on the screen, I cannot click on the notify window. There are two scenarios here: first the note pops up, then a modal window is opened; or the other way around: you receive the note while the modal window is on top. In both cases, I can't access the note. I looked at Outlook, how it behaves, and you can access the note (of course, trying to 'open' the email results in a warning message, stating it can't do that while modal windows are opened). I believe Outlook is using a different thread for the notes. I tried to do this, but it's not that easy. Notes must be _created_ (and displayed) on the 'notification thread'. Bottom line: I want to be able to create and display the notes from the gui thread, on the notes' thread (ideally I want only one thread for all notes, not one thread for each note). Any ideas are welcome. Thanks in advance, Cosmin. Tag: There is a pure win32 control, I don't know how it's created, But I just wanna show it in a form control Tag: 108227

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.

    - ANN: TayLayout Release 00.00.15 for IronPython TayLayout Release 00.00.15 for IronPython http://code.google.com/p/taylayout/downloads/list New This Release * Wordsearch generator sample (80% functional) * More controls specially supported (listbox, webbrowser) * More compound controls * Controls can now be right-aligned * Plenty of bug fixes TayLayout is a more sophisticated version of the flow layout - you can add controls to a panel or form and it takes care of positioning them. Controls are added in a Left to Right order until you specify that a new line is required.

    - 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?

    - 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?

    - Reason for Application.ThreadExit Hi, We have the strange problem that sometime in our application Application.ThreadExit is raised and out application shutting down. We do not see any previous exceptions before this event fires. Moreover the Application.ThreadException event is not fired at all, so we have not unhandled exceptions that occurs. We are working with SQL-2005 and with some unmanaged code too. What can be the reason for such behaviour ? And how can we catch such error ?

    - Render window to video port? Is it possible to redirect the rendering of a windows form to the video port/overlay device of a video card?

I need such library to make UML modeler with which i'd be able to make UML schemas(primarily for designing software projects).What i'm trying to achieve is to make something like any other UML drawing tool.

    - 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?

    - "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.

The point is I completely don't konw how the win32 control is created,
other than I can get its handle.
Besides, I have to show it in a windows form control, hwo to?
Thx.

I don't quite uderstand the question, but take a look at NativeWindow class.
usinng this type you can sub-class native controls in .NET
