Hello!
I'm loading the content of a database into a table and doing this
with a
TblSetLoadDataProcedure (table, 1, ListFormGetRecordField);
In ListFormGetRecordField I figured out how to do it, but I don't want
to send just one textfield to the table. I would like to combine two
fields of the database, create a handle to this textstring and send this one
to the TblSetLoadDataProcedure.
The first code example works with getting just a handle to the
database record, but the second one doesn't work.
Any ideas?
Many thanks, Dyk
recordH = DmQueryRecord(gItemsDB, recordNum);
ErrFatalDisplayIf ((! recordH), "Record not found");
packedRecordP = (PackedItems *) MemHandleLock(recordH);
UnpackItems(&record, packedRecordP);
// Calculate the offset from the start of the record.
recordP = MemHandleLock(recordH);
*textOffset = sizeof(UInt32) + sizeof(VeranstaltungDateTimeType);
*textAllocSize = StrLen (record.titel) + 1; // one for null terminator
MemHandleUnlock(recordH);
*textHP = recordH;
// the codesample above works great, the second one does not work!
StrCopy (strP, record.titel);
*textOffset = 0;
*textAllocSize = StrLen (strP) + 1; // one for null terminator
// get some space in which to stash the string.
txtH = MemHandleNew( StrLen( strP ) + 1);
txtP = MemHandleLock( txtH);
// copy the string.
StrCopy( txtP, strP );
MemHandleUnlock( txtH);
*textHP = txtH;
Any idea why the second example does not work and crashes with an alert:
The program X just changed the emulated program counter to 0x62616C6C. This
address is invalid because it's neither in ROM nor in RAM..
Many thanks,
dyk
