I am looking for a way to have some control over the shape of a simple MessageBox in Winforms. I would like to control where the passed in text wraps so that the dialog rect is narrower. Windows seems to want to make the dialog as wide as possible before wrapping the text. Is there an easy way to control the maximum width of the dialog w...
I'm trying to make a context menu for a control that is "linked" to a main menu item. There are two fixed menu items that are always there and an arbitrary number of additional menu items that might need to be on the menu. I've tried solving the problem by keeping a class-level reference to the fixed menu items and a list of the dynami...

I have a VB.NET Windows Forms project that at one point paints text directly to onto the form at runtime. Before I paint with the font though, I want to make sure that the font and font-size exists on the user's machine. If they don't, I'll try a few other similar fonts, eventually defaulting with Arial or something. What's the best way...
How do you draw a custom button next to the minimize, maximize and close buttons within the Titlebar of the Form? I know you need to use Win32 API calls and override the WndProc procedure, but I haven't been able to figure out a solution that works right. Does anyone know how to do this? More specifically, does anyone know a way to do ...

I've been developing Winforms applications in C# for a few years now and have been interested in moving future development toward WPF, mainly because of the positive things I've been hearing about it. But, I'm wondering what sort of hurdles others have had to overcome as they migrated to WPF. Was there a significant hit to your product...
I have a group of checkboxes that I only want to allow a set amount to be checked at any one time. If the newly checked checkbox pushes the count over the limit, I'd like the oldest checkbox to be automatically unchecked. The group of checkboxes all use the same event handler shown below. I have achieved the functionality with a Queue, ...
