Re: [WiX-users] Writing a C++ Custom Action Project

In C++ to test the C# equivalent of string.IsNullOrEmpty() you should do: if(( p == NULL) || (*p == NULL)) To sprintf a wide string you should use "%ls" Note that creating a file during an immediate custom action is against Windows Installer methodology. The correct way should consist of 3 custom
