Get a running process' dimensions

Question:

I'm trying to grab a screen shot of a specific x, y location in an application. Is there any way to get a running app in a Process object, then get the dimensions of it?

Something like:

Process[] processlist = Process.GetProcesses(); foreach (Process proc in processlist) { Console.WriteLine("Process: {0} ID: {1}", proc.Width, proc.Height); }

Answer1:

There are probably other ways to do this but here's a quick high level solution:

<ol><li>get the main window handle (<a href="http://msdn.microsoft.com/en-us/library/system.diagnostics.process.mainwindowhandle.aspx" rel="nofollow">Process.MainWindowHandle</a>).</li> <li>Get the window height using the win32 API function <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms633519%28v=vs.85%29.aspx" rel="nofollow">GetWindowRect</a></li> </ol>

This <a href="https://stackoverflow.com/a/6485074/52136" rel="nofollow">answer</a> to a SO question shows getting the window size and then setting it.

Edit: I realize this answer assumes that the process only has a single window. This SO <a href="https://stackoverflow.com/questions/79111/net-c-getting-child-windows-when-you-only-have-a-process-handle-or-pid" rel="nofollow">question/answer(s)</a> describes getting all of the windows for a process.
