OK here is all of it. Again, I am getting a record from a database. The
record is
"How many employees do you have?","1-100","101-1000","More than 1000"
So all I want to do is get
** "How many employees do you have? **
part of the string and add it to the list box. Right now it is blowing up at
the ****** shown in the code. Also with my _GetLastPos() function, I
allocate the string again. Since I did a previous MemHandleLock, I shouldn't
have to do this correct? Well the Enumulator keeps on saying I have access
memory I shouldn't...
Oh also, something is getting trampled because when the the line
VoidHand vHandle = MemHandleNew(wPos + 1);
get executed, it already has a value in it. MemSet() wont clear it either.
That is what the CW debugger shows...
Thanks for any help
