dll loading itself launching the application

[sujan.dasmahapatra]

Dear Friends
I am loading a dll from another exe mfc application. for that i have exposed one api 'runAppli' in the dll as extern "C". Then I am loading the dll using LoadLibrary. By loading the dll itself the dll application is launched. I am surprised. I should call the api 'runAppli' and then the application should launch but its not happening. How come it is happening please give some suggestions.

// in the all
extern "C" BOOL __declspec(dllexport) runAppli(CString filename)
{
    AFX_MANAGE_STATE(AfxGetStaticModuleState());
	if(filename.IsEmpty())
	return false;
	view->ShowWindow(SW_SHOW);
	view->loadProfile(filename);
	view->domainSetUpForProfile();
	view->drawLines();
	view->drawArcs();
	view->drawProfile();
    return true;
}

//in the client exe application

void CClientRevolutionProjDlg::OnBnClickedButton1()
{
HINSTANCE hinstLib;
hinstLib = LoadLibrary(L"C:\\Users\\sujan.dasmahapatra\\Documents\\Projects\\Bhagavan_SurfaceRevolution\\RevolutionProj\\debug\\RevolutionProj.dll");
}

By simply loading the dll the dll application is launching.. why ??? Thanks Sujan

If your dll is MFC regular dll, the behavior is by design. MFC framework launches application class' InitInstance when global theApp instance is constructed. This happens exactly at dll load time.
