Line 12 is pretty much useless. If LoadLibrary() fails then there is no reason to call FreeLibrary(). Call FreeLibrary() only when the process is done using it. Also, add an error message and return on line 13 when LoadLibrary() fails.

Why it fails to work the second time, I don't know.

I have got the problem I have implemented the PrecreateWindow for my view class.
just check this code.

BOOL CMyView::PreCreateWindow(CREATESTRUCT& cs)
{
	cs.lpszClass = ::AfxRegisterWndClass(CS_HREDRAW | CS_VREDRAW | CS_DBLCLKS | CS_OWNDC,::LoadCursor(NULL, IDC_ARROW), NULL, NULL);

    cs.style |= WS_CLIPSIBLINGS | WS_CLIPCHILDREN;

    cs.dwExStyle = WS_EX_CLIENTEDGE; 

	return CView::PreCreateWindow(cs);
}

If I remove the first line, i.e
cs.lpszClass = ::AfxRegisterWndClass(CS_HREDRAW | CS_VREDRAW | CS_DBLCLKS | CS_OWNDC,::LoadCursor(NULL, IDC_ARROW), NULL, NULL);
then my dll window is coming all the times from the client call. But it's flickering .
So now please help me what can I do to resolve this. I think some of you must have understood the problem, please help me. Thanks a lot.
