I have a WPF window that has a MaxWidth set, so when I hit the Maximize button, it maximizes vertically but not horizontally. This is expected behavior. However, the window always docks to the left side of the screen (Windows 7, if that matters) and I want it to be centered horizontally when Maximized. I tried adding the following Sta...
Hey All, I am creating a WPF screensaver, although this question isn't really WPF-specific. I have code to do a screen capture when the screensaver kicks in (using GDI+ and Interop).
