Invalid Handle

[bubak]

I have a programm, where I use WriteFile,ReadFile and CloseHandle, because of serial (com port) communication. It works ok, but when I try debugging it, it shows me :
First chance Exception in myprg.exe (NTDLL.DLL) 0xC00000008 Invalid Handle. I'm Using VC6 and NT4, all other programs r working and also debuging fine, so I there must be sth. in this one, but I don't know what.
Thanx

try to put file you open in the projects current directory, not in subdirectory debug. Or spacifi in the program the full path to your file. John Fill
