Declare Function SetActiveWindow Lib "user32.dll" (ByVal hwnd As IntPtr) As IntPtr
Private Enum ShowWindowEnum
    Hide = 0
    ShowNormal = 1
    ShowMinimized = 2
    ShowMaximized = 3
    Maximize = 3
    ShowNormalNoActivate = 4
    Show = 5
    Minimize = 6
    ShowMinNoActivate = 7
    ShowNoActivate = 8
    Restore = 9
    ShowDefault = 10
    ForceMinimized = 11
End Enum

Use Process.MainWindowHandle to get the handle. This works on most, but not all, applications.
