I tried setting the handle to null in previous versions (several of them)
of the code I posted but I took it out. My understanding is that if the
field has nothing in it there will be a null pointer. Right? I put the
FldSetTextHandle(fldP, NULL) back in but only when there is a pointer.
Actually, there never is because the fields in question are never updated a
second time. The only time the fields are drawn is right after the form is
loaded. Is my understanding of this correct? Anyway I put it back in last
night both with a test for a null pointer and without and it still doesn't
work.
I wonder if I'm loading the forms correctly. I adhered to the method in
one of the examples.
The second form - the one on which I can't refresh is loaded like so. It
starts with a menu option on the main form.
case menuEvent:
//
return MainFormDoCommand(eventP->data.menu.itemID);
break;
Then it goes here:
// Process the option selections on the main form
static Boolean MainFormDoCommand(Word command)
{
Boolean handled = false;
switch (command)
{
case MainOptionsAboutBusyBeaver:
MenuEraseStatus (0);
FrmGotoForm(AboutBusyBeaverForm);
handled = true;
break;
case MainOptionsLogonLogoff:
MenuEraseStatus (0);
FrmGotoForm(LogonLogoffForm);
handled = true;
break;
--> case MainOptionsSignageCount:
MenuEraseStatus (0);
FrmGotoForm(EnterKeyForm);
handled = true;
break;
}
return handled;
}
Then here:
case frmOpenEvent:
frmP = FrmGetActiveForm();
FrmDrawForm ( frmP);
handled = true;
break;
}
return handled;
Is there anything I should be doing different to open the form?
I can do a lot of things without incident before after the form opens
before I try to update that field. I open a database and do a binary search
then move several strings around. As soon as I try to display a string it
blows up on the FldSetTextHandle instruction. If I don't try to update a
field on the second form I can move back and forth between the first and
second form. Each time the first form is loaded it puts text in eight
fields.
