Question

LoadLibrary to load dll in C++

Asked by: KavyaAS

Hi Experts,

      typedef bool (*LPFunctionType)(BSTR);
      HINSTANCE  hInstLib;
      LPFunctionType functionptr=NULL;
      LoadLibrary("XMLTest.dll");

      BSTR *bs=SysAllocString(L"SanityMonitor warning");
      functionptr=(LPFunctionType)GetProcAddress(hInstLib,"ReadXmlFile");
            //functionptr("");
}


Above is the way I've tried to call dll, where ReadXmlFile is a function within XMLTest.dll in C++. I'm a beginner. Please help as I'd go mad by the time I learn to do this
