Return value

Type: HWND

If the function succeeds, the return value is the handle to the window that owns the clipboard.

If the clipboard is not owned, the return value is NULL. To get extended error information, call GetLastError.

Did you call GetLastError()?

Thank you Paul McKenzie , yes i called GetLastError() , but it returns 0 as a result just with acrobat reader , not for Notepad.exe ...etc

So what's the problem with adobe acrobat reader ? do they use an other TECH with their Clipboard or what ?

I think knowing the owner of the clippoard isn't very useful information.
Just imagine clipboard data from lets say MS Word over a remote desktop connection.
Should it return the HWND of the remote desktop window or should it even return the HWND of the Word window on the remote machine ?

thank you ZuK , but i really need to get the Clipboard Owner by Calling the GetClipBoardOwner ,
my question is just why GetLastError() return 0 with acrobat reader ?

really strange

Why should it. According to Paul's link it is not an error

The clipboard can still contain data even if the clipboard is not currently owned.

ZuK , ok then is there any other alternative to get the Clipboard Owner ? without using :
GetClipBoardOwner ..

GetClipBoardOwner is a Windows API function. That is the way to get the clipboard owner. Unless you know some undocumented function, that's the function you must use.

Maybe there is no owner. Have you considered that? So if there is no owner, what do you intend to do?

You don't know how internally Acrobat communicates with the clipboard, since you didn't write the Acrobat application. So assuming that Acrobat owns the clipboard is more than likely a wrong assumption.
