Rather than show the user the splash screen, I'd like to hide the application for the first couple of seconds after starting it by keeping my window topmost and maximized. The problem is that starting this application automatic...
I am new to Visual Studio 2008, and I am learning the old "Hello World" application using a WPF application. When I click 'Start without Debugging' I see a window open for a half-second on my taskbar, and then close. I dont get any window that stays open with my application in it. I cannot figure out why this is happening. If I trying op...
Similar to this question, except the console program being wrapped up in the WPF application produces coloured output, so it would be nice if I could capture the colour as well as the text. This is my first WPF program and I'm not sure how to go about finding/modifying the right control, currently I'm just using a TextBox which works bu...
I have a live 16-bit gray-scale video stream that is pushed through a ring-buffer in memory as a raw, uncompressed byte stream (2 bytes per pixel, 2^18 pixels/frame, 32 frames/sec). (This is coming from a scientific grade camera, via a PCI frame-grabber). I would like to do some simple processing on the video (clip dynamic range, color...

I have a ListBox with a rather simple ItemTemplate defined - containing a TextBlock and a Button. This displays like expected, but there is a problem though. When I click the content of the ListBoxItem, i.e. the text or the button, the line doesn't get selected in the ListBox. If I click the blank parts of the line it does. I'd like the ...

I'm downloading a webpage, and then loading strings from the page into a WPF UI. One string has an accented character: "Ãine". In the debugger, the string looks fine, but when added to a WPF ListBox, it appears like this: Ã[]ine, where [] is a single rectangular symbol. When I copy the text from the debugger UI and paste it, a space ap...
I'm trying to get a better understanding of what dependency properties and what they are not.

Okay, I've not done much WPF lately and this is confusing me. I have a Style defined for RadioButton, which uses a ControlTemplate with a MultiTrigger. The gist is that I want a Border to become opaque when the mouse either hovers over it or when it's IsChecked is true. So I have the MultiTrigger, which animates the Opacity in and ou...

I have an application that, due to OpenGL airspace issues, has to host several controls in separate, exclusive windows. This is working quite well, but I am setting all of the windows to TopMost=true, which means that they do stay showing even when they lose focus, but they also overlay other applications... Also, it kind of binds me t...

But when it pops...
