Maximize another process' Window in .NET

Question

I have a handle on another process\' main window in .net (proc.MainWindowHandle). How do I maximize the window inside of .net?

Answer 1

You can pinvoke to ShowWindow with SW_SHOWMAXIMIZED to maximize the window.

Pinvoke.net has an entry for ShowWindow here.

For example,

// Pinvoke declaration for ShowWindow
private const int SW_SHOWMAXIMIZED = 3;

[DllImport("user32.dll")]
static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

// Sample usage
ShowWindow(proc.MainWindowHandle, SW_SHOWMAXIMIZED);
