Hi, I just made the steps to install Visual Studio 2008 (as you said me) with all the includes and libraries (even the include from suid source), I took the otpion "create project from existing code" taking as folder and files "mswin_ad_group" from the source of squid (containing so: mswin_check_ad_group.c ; mswin_check_ad_group.h and the "make" files). I choose to make as output a "windows application" to have a .exe at the end of the process. Seems there are not problems but when I ask to "build" show up an error message referring to my file: "does not contain a static Main method suitable for an entry point ". I check and in mswin_check_ad_group.c the main is there (no static)! How do I must procede?I need only to exchange one line of the original code and have again the executive of this helper, but how can I make that if even the original code doesn´t give me an .exe as output? Please, I ask for a quick help cause now I arrived at this point I´d like to reach my aim. It´s quite urgent so I hope in an answer from someone. Thaks to everybody in advance Antonio
