Myfilestream:=TFileStream.Create(OpenDialog1.FileName,fmOpenRead);
Myjimifilesteam:=TFileStream.Create(OpenDialog2.FileName,fmOpenRead);
Mymemorystream:=TMemoryStream.Create;
Myfilestream.Read(arrbyte,arrLen);
Mymemorystream.Write(arrbyte,arrLen);
Myfilestream.Free;
iTemp:=Myjimifilesteam.Read(Buf,4);
加密过程
Mymemorystream.Write(buf,4);
Mymemorystream.SaveToFile(OpenDialog1.FileName);、
到最后总是暴错
怎么办
