My WinForms app uses Process.Start() to open files in their native app. I want to split the screen in half, showing my WinForms app on one half and the new process on the other. I know I can use Process.MainWindowHandle to get the window handle, but how can I set its size and position? I imagine I have have to use some kind of Windows ...
I have this code for an ownerdrawn list box that is repainting too frequently. It seems to be related to trying to scroll an event with a different height than normal. Here is the 'smallest code to reproduce the problem' that can be pasted into a blank form (erase the designer file) - VB version (c# of course does the same thing): Publ...

In this case it will become unreadable for many color combinations (because i am giving options to change color of a form for user at run time). I can use ReadOnly property but it is available only to TextBox controls not for other controls li...
When using asynchronous code to read from streams etc using the BeginXXX / EndXXX pattern, I believe that any exceptions that occur during the process will be thrown when the call to EndXXX is made. Does this mean that the initial call to BeginXXX will never throw an exception, it will always be thrown by EndXXX? Or to put it another w...
I doubt this is even possible. So your app is running and user decides to End Process via Task Manager. Is there a method/action to save data during process.kill? I doubt there is but I had to ask. Also, if a user shuts down/restarts PC (as in windows update/manual restart), what action would the app execute? Window_Unloaded? On this s...
Why is there a difference in the way the Application object is created in WinForms and WPF? -> In WinForms we never created the Application object. It was always available (I believe it was Singleton pattern). In WPF, although hidden in App.g.cs we need to instantiate one. -> In WinForms it was a sealed class, but in WPF the way to go ...

I want to show a print preview dialog for a WebBrowser control that I have in a WinForms application. I am using .NET framework 3.5. I am aware that I can show a print preview dialog as follows: webBrowser1.ShowPrintPreviewDialog(); But I would like to perform some operations on that dialog, namely specify its size. In order to do this...
I'm looking for a winforms control that can output text like in a console window (output is appended to the bottom, color formatting, etc.) Much like the "output" window in most IDEs. I tried making one myself but it didn't work the way I wanted, so I'm wondering if there is some existing control out there. This is for an open-source p...
