DmRecordInfo (MemoPadDB , index , NULL , &uniqueIDP, NULL );

[NGrant.com]

Hi
 

I have been having a little trouble with the call DmRecordInfo, from the doco I believe that uniqueIDP should return a "unique" value, this code doesnt it is always the same value, which obviously isnt "unique".

 

This must be something simple but I cannot get past this problem.

 

Any one got any ideas ?
 

 Ptr   pRec;
 VoidHand memoRec;
 Err   error;
 UInt      mode;
 DmOpenRef MemoPadDB;
 UInt32  memoPadDBType = 'DATA';
 UInt16  index;
 UInt32   uniqueIDP = 0;

 mode = dmModeReadWrite;

    MemoPadDB =  DmOpenDatabaseByTypeCreator(memoPadDBType, sysFileCMemo ,mode); //memoPadDBType is 'DATA'

// Get index of new memo record to be added.
 index = 0; // befinning of DB
  
 // Create a new record in the database
 memoRec = DmNewRecord(MemoPadDB, &index, StrLen(data) + 1);
 // Lock down the block containing the new record.
 pRec = (Char*)MemHandleLock(memoRec);
 DmStrCopy (pRec, index , data); 

 // Unlock the block of the new record.
 error = MemPtrUnlock(pRec);
 if (error != 0)
  return error;

 error = DmReleaseRecord (MemoPadDB, index, true);
 if (error != 0)
  return error;

   error = DmRecordInfo( MemoPadDB, index, NULL, &uniqueIDP, NULL);
 if (error != 0)
  return error;

// Debug -> display the value, always 16

 gUniqueIDP = uniqueIDP;

    char buf[32];
   
     //send received data to display
     StrPrintF(buf,"gUniqueIDP: %i", gUniqueIDP);
   
    FrmCustomAlert
    (
     DebugScreenAlert ,
     "No error on create of memo",
     "gUniqueIDP",
     buf
    );

// Debug -> display the value, always 16

    
  
 // Close the application's database.
 DmCloseDatabase(MemoPadDB);
 

I have tried the DmRecordInfo before the release as well, but no joy :(

 

Thanks for your help in advance.
