Handle external windows using java

Question

I need to check if an external window (another java program, but not controlled by the program that I\'m working on) is open using the title, and if it open, then either max

Answer 1

You can use the Windows API to get a handle to the window and then resize it:

EnumWindows:

GetNextWindow:
http://msdn.microsoft.com/en-us/library/ms633509%28v=VS.85%29.aspx

GetWindowText:   (to decide whether that is the window you want; if title matches)
http://msdn.microsoft.com/en-us/library/ms633520%28v=VS.85%29.aspx

FindWindow:  (for this you need the exact title beforehand, not just part of it)
http://msdn.microsoft.com/en-us/library/ms633499%28v=vs.85%29.aspx

ShowWindow:

Typical WinAPI interface, a little clunky to use but powerful.
