printer = fopen("PRN","w");
fprintf(printer,"any variable",....):
When I run this one from the RUN menu in Windows, it works fine, but if I run it from Forms through DDE.App_Begin, Host or Win_Api_Shell.WinExec, I get a null pointer as the return value for the printer descriptor. I think that this is caused by some enviromental variable lost, so my question is:
Does anybody knows how can I get that Forms recognize PRN as LPT1? Thanks a lot for your answers
