Hello all, I have the problem mentionned here: http://forums.ni.com/ni/board/message?board.id=180&thread.id=21763 But the last message which appears to be a fix doesn't work for me. Let's see if I got it right: - have a UIR control - set a tooltip on it - duplicate it - InstallCtrlCallback(,,NULL,0) on the duplicate - discard the duplicate I have the error when I try to update the tooltip text with SetCtrlToolTipAttribute on the original control. What is the difference between doing InstallCtrlCallback(panel, Dup, cb_Func, 0) and SetCtrlAttribute(panel, Dup, ATTR_CALLBACK_FUNCTION_POINTER, cb_Func) besides the ability to pass callback data with the former ? -- Guillaume Dargaud http://www.gdargaud.net/

Error when discarding duplicated control with tool tip

I just had a hunch... Is SetCtrlToolTipAttribute thread-safe ?
Sometimes I call it from one thread, sometimes from another, for the same
control. And it seems to fail only randomly...
