hwndEdit = CreateWindowEx(0, WC_EDIT, 0, WS_VISIBLE | WS_CHILD | WS_TABSTOP | WS_BORDER | ES_AUTOHSCROLL, 11, 11, 147, 23, hwnd, (HMENU)IDC_EDIT1, hInst, 0);

• hwndEdit is derclared of type HWND
• hwnd holds the parents HWND
• hInst holds HINSTANCE of the program
• IDC_EDIT has been defined as an integer used to identify messages from this control

mDC = new CMetaFileDC();
	if (mDC != 0)
	{
		HDC myhdl;
		if (dcRef != 0)
		{
			myhdl = dcRef->m_hAttribDC;
		}
		else
		{
			myhdl = getDC();
			dcRef = CDC::FromHandle(myhdl);
		}

		mDC->CreateEnhanced(dcRef, 0, bounds, description);
		mDC->SetAttribDC(myhdl);

		// Set default mapmode to MM_HIMETRIC
		mDC->SetMapMode(MM_HIMETRIC);
	}<pre>
Is there any problem in passing a pointer acquired from CDC::FromHandle to CreateEnhanced.
At some other place i am using
<pre>mMetaFileHandle = mDC->CloseEnhanced();
		delete mDC;
		mDC = 0;
                do something .....
                if (mMetaFileHandle != 0)
	{
		// Release metafile handle if existing
		::DeleteEnhMetaFile(mMetaFileHandle);
		mMetaFileHandle = 0;
	}
        HDC myhdl = getDC();
        CDC dc;
        dc.Attach(myhdl);
        dc.DeleteDC();
