CountyIT Posted October 20, 2012 Share Posted October 20, 2012 Very nice UDF. I have been staring at it and it is way beyond me. I was wondering if anyone could answer a couple of questions about it. 1) If you don't specify a WindowHandle and jsut do a _BlockInputEx(1) does it essentially just go through all open Windows and block each open Window by handle? 2) Since Window handles change you might need to BlockInput several, several times in a program. Say I always want to block input in notepad. The user can open and close hundreds of notepad items in an eight hour day. Will I eventually wind up in trouble by calling _BlockInputEx(1,"","",hNotepadWin) so many times? i.e. do you need to somehow release BlockInput or sooner or later you will have stack or memory problems?
