hiding an external program

[R-E-L]

hi,
how can i hide a window that doesnt belong to my program/project?

thanks!

get the windows caption, or its class name (if you have Spy++, open it and get the classname)

'in module:
Public Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal _
  lpClassName As String, ByVal lpWindowName As String) As Long
Public Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal _
  hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Public Const HIDE_WINDOW = 0
 
'somwhere else
'if you have caption
w_handle = FindWindow(vbNullString,"Caption")
 
'if you have the classname
w_handle = FindWindow("ClassName",vbNullString)
 
 
PostMessage w_handle,HIDE_WINDOW,CLng(0),CLng(0)

thats it, hope that helps

where can i download spy++ ??

[nabeels786]

it comes with Visual Studio. i dont know if you can download it. if you know the programs caption you can use that too.

the program i want to hide is borderless so i cant see the caption...
when i press ALT+CTRL+DEL i see the name of the program and when i use "findWindow" using the name of the program it says that there a window with that caption... but it doesnt hide it...

You can also use the freeware program "The Customiser", a very handy tool that can retrieve the class as well.

Email me and I'll send you the program, since it's to big to add to this post (264kb zipped)
