Basically, we can use the Windows API ShowWindowAsync function to normalize/maximize/minimize another application. Please refer to the code snippet below for an example:
Code Snippet:
private const int SW_SHOWNORMAL = 1;
private const int SW_SHOWMINIMIZED = 2;
private const int SW_SHOWMAXIMIZED = 3;
[DllImport("user32.dll")]
private static extern bool ShowWindowAsync(IntPtr hWnd, int nCmdShow);
private void button1_Click(object sender, EventArgs e)
{
// retrieve Notepad main window handle
IntPtr hWnd = FindWindow("Notepad", "Untitled - Notepad");
if (!hWnd.Equals(IntPtr.Zero))
{
// SW_SHOWMAXIMIZED to maximize the window
// SW_SHOWMINIMIZED to minimize the window
// SW_SHOWNORMAL to make the window be normal size
ShowWindowAsync(hWnd, SW_SHOWMAXIMIZED);
}
}
