Well i'll try to expalin as clear as possible,
I'm using a structure as i told you(the def for the
structure is below). In my code i'm only trying to
store data in SoldToParty
member only(just for testing purposes).
Here's the code for storing the record.
=======================================
frm = FrmGetActiveForm();
fldIndex = FrmGetObjectIndex(frm,
SalesOrderDetailsSoldToPartyField);
fld = FrmGetObjectPtr(frm,fldIndex);
// Get a pointer to the field's text.
text = FldGetTextPtr(fld);
MemHandle myRecord = DmGetRecord(SAPDB,
CurrentRecord);
OrderInfoType *s = MemHandleLock(myRecord);
myStruct = *s;
myStruct.SoldToParty = (Char *)MemPtrNew(20);
StrCopy(myStruct.SoldToParty,text);
DmWrite(s, 0, &myStruct, sizeof(myStruct));
MemHandleUnlock(myRecord);
DmReleaseRecord(SAPDB, CurrentRecord, true);
Here's the code which i have put to retrieve the data
from the struct.
=======================================================
if ((CurrentRecord != noRecordSelected) &&
(DmNumRecords(SAPDB) > 0))
{
recHandle = DmQueryRecord(SAPDB,CurrentRecord);
StructType *pt = MemHandleLock(recHandle);
FldSetText(fld,recHandle,OffsetOf(StructType,SoldToParty),sizeof(pt->SoldToParty));
}
I have followed the MemoPad example's to come this
far. Can you tell me what i have done wrong.
Regards
Dhanushka.
