Well, I learned my lesson, next time I ask a question about any language, I will surely post the variable declarations to the net. Sorry Guys! The problem was that I was using the declaration int surround[9] as if I could use the variable surround[9]. That was mistaken, and as someone pointed out, I can't, well shouldn't use the variable surround[9] becuase it would probably overwrite the variable that was next in memory. Guess what everyone, It was overwriting one of the variables of the for loop that was overwritten!! Thanks.

I seem to be having a great deal of difficulty getting the dialog manager to draw my userItem. It seems that when I attempt to return from the function in which the drawing occurs, that it is returning to some unknown memory location (somewhere not in my program atleast) and crashing. I have been writing this on a Mac IIci with Think C 4.0. I call the routines to set up the function call as follows : GetDItem(theDialog,itemNo,&itemType,&item,&box); item = (Handle)DrawItem; SetDItem(theDialog,itemNo,itemType,item,&box); Then I use DrawDialog(theDialog) to draw it. The problem does not have anything with what happens in my Draw function. Any insights into this problem would be greatly appreciated. Doug Rusch -RPI

I don't know if this is your problem, but one quick 'n' easy way to crash a program is to forget to declare routines that are passed as callbacks to ToolBox routines as *pascal* routines. If your function is DrawItem (...) instead of pascal DrawItem(...) you'll have some difficulties. -- Paul DuBois dubois@primate.wisc.edu
