you can't free the handle after you give it to the field.
You would be better off if you:
=>get the current handle from the field
creating your new handle
copy your string to the handle
assign the new handle to the field
=>delete the old handle
=>do not delete the new handle

Subject: Reading directly from unlocked memory chunk: Please help
Hi,
I am trying to display text on to a field object by using the following
function :-
void DisplayTxtToField(FormPtr frm, UInt16 fieldID, Char* tempString)
{
MemHandle userTextH;
FieldPtr fldP;
Err err;
fldP = FrmGetObjectPtr(frm,FrmGetObjectIndex (frm, fieldID));
userTextH = MemHandleNew( StrLen(tempString) + 1);
StrCopy(MemHandleLock(userTextH), tempString );
MemHandleUnlock(userTextH);
FldSetTextHandle(fldP,userTextH);
FldDrawField(fldP);
err = MemHandleFree(userTextH);
}
where tempString stores the text to be displayed....
The first time I call the function it works fine...but the second time
around
I get this error
: Browser has just read directly from an unlocked memory chunk.
Is there something wrong in the code?
Thanks in advance
vishy
