OpenClipboard

The OpenClipboard function opens the clipboard for examination and prevents other applications from modifying the clipboard content.

BOOL OpenClipboard(
  HWND hWndNewOwner   // handle to window
);

Parameters

hWndNewOwner

[in] Handle to the window to be associated with the open clipboard. If this parameter is NULL, the open clipboard is associated with the current task.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

OpenClipboard fails if another window has the clipboard open.

An application should call the CloseClipboard function after every successful call to OpenClipboard.

The window identified by the hWndNewOwner parameter does not become the clipboard owner unless the EmptyClipboard function is called.

Requirements

  Windows NT/2000: Requires Windows NT 3.1 or later.
  Windows 95/98: Requires Windows 95 or later.
  Header: Declared in Winuser.h; include Windows.h.
