Description

You can close or exit any program by using this code.

This code won't work with all programs, but it will with most of them. If the code doesn't work as it is written here, try uncommenting the 'SendMessage $0 ${WM_DESTROY} 0 0' and comment the 'SendMessage $0 ${WM_CLOSE} 0 0' line. Winamp 2 (and propably Winamp 3 too) can be closed with the 'SendMessage $0 ${WM_CLOSE} 0 0' line.

To use this function push the window's class name and call the function.

Example

Push "Winamp v1.x"
Call un.CloseProgram

This piece of code will close down Winamp 1, 2 or 5. To close Winamp 3, use the following code:

Push "STUDIO"
Call un.CloseProgram

To find out other windows' classes ("Winamp v1.x" in Winamp 1/2/5's case) use a program such as Win32Spy (open source).

The Function

!include WinMessages.nsh
 
Function un.CloseProgram 
  Exch $1
  Push $0
  loop:
    FindWindow $0 $1
    IntCmp $0 0 done
      #SendMessage $0 ${WM_DESTROY} 0 0
      SendMessage $0 ${WM_CLOSE} 0 0
    Sleep 100 
    Goto loop 
  done: 
  Pop $0 
  Pop $1
FunctionEnd
