Hello,
I have a big problem for my palm program. in my program, I let user input two
field and save the value into the database.
but it always show "DmWrite:DmWriteCheck failed" when I insert a longer value than
before into the database. how can I handle this?
following is my code:
Err SaveUserProfile(Char *UserID, Char *Passwd)
{
Char *ProductID, *tmp="";
Err error;
DmOpenRef dbRef;
Char *pMypointer, *pCurrPos;
int numRecs=0, indx=0, SerialLen=0;
MemHandle recH;
MemPtr recP;
tmp = GetSerialNum(&SerialLen);
ProductID = new char[SerialLen];
StrNCopy(ProductID, tmp, SerialLen);
error = CheckOrgeDB();
if ( error >= 0 )
{
dbRef = OpenDBByName(DBNAME,MODE);
if (dbRef)
{
numRecs = DmNumRecords(dbRef);
pMypointer = (Char *)MemPtrNew(500);
pCurrPos = pMypointer;
StrCopy(pCurrPos, UserID);
pCurrPos += StrLen(UserID) + 1;
StrCopy(pCurrPos, Passwd);
pCurrPos += StrLen(Passwd) + 1;
StrCopy(pCurrPos, ProductID);
pCurrPos += StrLen(ProductID) + 1;
if ( numRecs > 0 )
{
int fsize = pCurrPos - pMypointer;
DmResizeRecord( dbRef, 0, (pCurrPos - pMypointer));
recH = DmGetRecord( dbRef, 0 );
recP = MemHandleLock(recH);
error = DmWrite (recP, 0 , pMypointer , (pCurrPos -
pMypointer));
if (error)
FrmAlert(Profile_WriteRec_Alert);
MemHandleUnlock(recH);
DmReleaseRecord( dbRef, 0, true);
profile_data_modify = false;
} else{
recH =
DmNewRecord(dbRef,0,(pCurrPos-pMypointer));
recP = MemHandleLock(recH);
indx = 0;
error = DmWrite (recP, 0 , pMypointer ,
(pCurrPos - pMypointer));
if (error)
FrmAlert(Profile_InsertRec_Alert);
MemHandleUnlock(recH);
DmReleaseRecord( dbRef, 0, true);
profile_data_modify = false;
}
MemPtrFree(pMypointer );
DmCloseDatabase(dbRef);
}
}
return 1;
}
