I hate to ask this since so much has already been posted about fields,
but....
I can't seem to be able to get the text from a field and copy it into a
string. Setting the text to the field is no problem.
the code is
static void GetFieldText(UInt32 FieldID, char *Text)
{
FieldPtr FieldP;
Handle FieldHand;
CharPtr TextP;
FieldP = (FieldPtr)GetObjectPtr(FieldID);
FieldHand = FldGetTextHandle(FieldP);
TextP = MemHandleLock(FieldHand);
StrCopy(Text,TextP);
}
I also tried
{
TextP = FldGetTextPtr(FieldP);
StrCopy(Text,TextP);
}
This function is called when hitting a "Save" button in which I want to save
the field text in the preferencetype struct.
When run in the emulator, I get a "bus error" and on the actual device I get
a fatal exception.
Am I missing something here?
thanks for the help
Jim
