Hi ,I am new in mfc and c++, and currently I have got problem with this kind of error basically , i have to file get.cpp and send.cpp and i want to share variable across that files and i thought we can use keyword "extern" so here is my code in send.h int g_iEnabled class csend { ...... } in get.h extern int g_iEnabled class cget { .... } is that the rightway to share variable across multiple files thanks for your help bye :-D

Put the int g_iEnabled declaration in the .cpp file.
