That's what I get for not just copying the hole thing and trying to do it
one line at a time, I was trying to only copy what was revenant, but it is
Char buffer[81] in the code. Anyway I tried skipping the hole buffer thing
and tried to copy a string into ptext like this
ptext=MemHandleLock(htext);
StrCopy(ptext,"This is a test");
MemHandleUnlock(htext);
FrmDrawForm(frm);
and I still only get the 5 charactors to dislplay, no mater what string I
try to load into it. I don't know what is going on.
Any Ideas?
I just noticed your slightly bizarre declaration section:
> > MemHandle htext;
> > FieldPtr fld;
> > FormPrt frm;
> > char* ptext;
> > buffer[81]
Don't you mean "Char buffer[81];"? I'd expect the compiler to complain
about that.
