Once you unlock the handle, the OS can move the memory around if it needs to. Therefore, you should not try to use the pointer after unlocking the handle. MemHandle recordH = DmQueryRecord(myDB, index); if (recordH == NULL) return; MyRecordStruct *recordP = MemHandleLock(recordH); MemMove(myStructP, recordP, sizeof(MyRecordStruct)); MemHandleUnlock(recordH); Just checking...So, I can still access myStructP, since I now have my own copy of the data, right? -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
