MainWindow of dll how to launch from client exe
Dear Friends I have two mfc application. One is a dll and the other one is a client:) exe application. From the exe application I am trying to load the dll and launch the mainwindow of the dll.
For that in dll.....I have the view class there in view implementation file i am declaring a view pointer, like the code below

//RevolutionProjView.cpp file
CRevolutionProjView *view;
 view = this;
// The I am creating an extern C function by name runAppli like below.
extern "C" BOOL __declspec(dllexport) runAppli(void)
  return true;

Now I have exe applicatioln where I want to launch the mainwindow of the dll above is given below.

void CClientRevProjDlg::OnBnClickedButton1()
    typedef VOID (*MYPROC)(void);
    HINSTANCE hinstLib;
    MYPROC ProcAdd;
    BOOL fFreeResult, fRunTimeLinkSuccess = FALSE;
    hinstLib = LoadLibrary(L"C:\\Users\\DasmahapatraS\\Projects\\Bhagavan_Cadem\\RevolutionProj_OrthoGraphic\\debug\\RevolutionProj.dll");
 if (hinstLib != NULL)
        ProcAdd = (MYPROC) GetProcAddress(hinstLib, "runAppli");
        if (fRunTimeLinkSuccess = (ProcAdd != NULL))
        (ProcAdd) ();
        fFreeResult = FreeLibrary(hinstLib);
    if (! fRunTimeLinkSuccess)
        printf("message via alternative method\n");

With this my application mainwindow is appearing but immediately its crashing. Can anyone tell me whats going wrong. How can I launch the mainwindow of the dll ?? Please help me. Thanks Sujan
