ok, i've figured out the original issue regarding handles vs ptr. That was the main problem I had before. Everything now seems to be going ok except for one thing. After I dynamically append 3 chars to any of my fields that use this number pad and then attempt to grafitti a back space I get the following error:
DataMgr.c...DmWrite:DmWriteCheck failed I'm not making any calls to DmWrite? Not sure exactly what is going on. Any help is appreciated.
