Kramps Posts: 66 Rating: (2)	Hi, I want to use the function "MessageBox" in a C script. I'm having a little problem with it: The Message Box displays itself but not at the top of my WinCC Window (which is in fullscreen). I guess it's a problem with the first argument of the function, I've checked "NULL" for the moment but I have no clue what else to put in this argument. Have you got an idea? Thanks Kramps

Ikkezelf Posts: 1084 Rating: (72)	Hi, If you use the following syntax you are able to display a messagebox on top of any other window and it stays there until you have pressed <YES> or <NO>. And it gives you the pressed button as a returnvalue. [code] ReturnValue = MessageBox(NULL,"Are you sure you want to...?","Confirmation Box",MB_YESNO\|MB_ICONQUESTION\|MB_SETFOREGROUND\|MB_SYSTEMMODAL); [/code] With regards, Ikkezelf
