I'm using the Windows Forms WebBrowser control, and getting it to display a document that I create on the fly and set using the DocumentText property. The document that I create references a script file in the same directory as my executable. Trouble is, when the WebBrowser control displays the page, the scripts aren't enabled. Now I kn...
My question is about the Visual Studio Image Library that comes with VS2008. In the _Common Elements\Annotations folder, there are PNGs with multiple sizes and I was wondering what the intended use of these is.

I'm designing some dialog boxes, and I'm having a hard time to fit everything. (and it has to fit on a single dialog box by design, so please don't tell me I should make two dialogs instead of one:)) I'm wondering what's the max size a dialog can have before being annoying for the end user. Of course it should't be bigger than his resol...
I've written an extended ListView in C# WinForms. It's purpose is to show a list of currently running applications using the WinAPI. However, If I try to populate the ListView in the constructor it works when I run the application, but if you try to put the control on any form it will crash VS 2008. The reason for the crashing is I beli...
I have a WinForms user control that, when added to a form, should automatically add some elements to application settings. (Of course, the user should be able to customize/disable this behavior.) is that advisable? What is the "good" way to do this? [edit] The control provides a default implementation for the file menu, the consumer on...
I have a TabControl with 5 tabs, and the contents of one of the tabs depends on some conditions or modes - Sometimes it needs to show one set of controls, on other times it should show an entirely different set of controls. What is the easiest way to achieve this? I tried setting up two different tabs, and using something like tab.Enabl...

I means that: All the screens have an hierarchy organization All the nodes on TreeView have one and only one screen related. A screen gets activated when a node on treeview gets selected. One of the advantages i...
The Winforms System.Windows.Forms.Control class has an instance method "DrawToBitmap" which I think is very useful in a variety of circumstances. I'm wondering if there's an equivalent way of getting a System.Drawing.Bitmap from a WPF application? I realize I could do some P/Invoke stuff to just get the application window, however I ...

Hi All, I'm looking for a trackbar-like user/custom control to use in my .NET 2.0 WinForms app. Note: I'm NOT asking how to control the volume in a WinForms app. Anyone knows of a nice looking custom painted slider/trackbar control that could be used in my app to let user set the volume?

Well my problem is this: I set the AcceptButton on a form and this gives me the nice effect that it triggers the buttons Click event, but if I'm on a MultiLine textbox I don't want this to happen. Then I just want it to put a enter in it. Is there any way to do this? ...
Is it possible to have variable-height rows within a WinForms ListView in Details mode? There is no RowHeight or Rows[i].Height property on the control as far as I know. Some blogs suggests implementing OwnerDraw, which I did, but I still can't find anything resembling height property from within the event handlers. Ideally, the row ...
I've got a list view that I'm populating with 8 columns of user data. The user has the option to enable auto refreshing, which causes the ListView to be cleared and repopulated with the latest data from the database. The problem is that when the items are cleared and repopulated, the visible area jumps back to the top of the list. So if...

We've been using WinForms up until now but there's a couple of new tools on the drawing board and I...

I'm currently investigating a problem with a 3rd party component (DevExpress) in my application. My issue is quite similar to this one DevExpress KB article. I get the same exception with more less the same stacktrace. So I used .NET Reflector to find out, what may be null in this scenario, and the only object which is a candiate to be n...
