MORE INFORMATION

Steps to Reproduce Behavior

  1. Using Visual C++ 6.0, create a new ATL project via the ATL COM AppWizard. Pick DLL as the Server Type and leave the rest of the options unchanged.
  2. Insert a new Full Control from the Insert/New ATL Object menu. Be sure to add support for the Backcolor Stock Property from the Stock Properties Page.
  3. Change the OnDraw code for the generated control to the following:
    	HRESULT OnDraw(ATL_DRAWINFO& di)
	{
            RECT& rc = *(RECT*)di.prcBounds;
  
            HBRUSH hbr = CreateSolidBrush(m_clrBackColor);
            FillRect(di.hdcDraw, (const RECT*) di.prcBounds, hbr);
            DeleteObject(hbr);

            SetTextAlign(di.hdcDraw, TA_CENTER|TA_BASELINE);
            LPCTSTR pszText = _T("ATL 3.0 : StockReproTest");
            TextOut(di.hdcDraw, 
                (rc.left + rc.right) / 2, 
                (rc.top + rc.bottom) / 2, 
                pszText, 
                lstrlen(pszText));

            return S_OK;
         }
  4. Build the ATL project.
  5. Insert four copies of the control into the ActiveX Control Test Container.
  6. Select all four controls. A rectangle should appear around each one.
  7. Select the Edit/Properties menu item.
  8. Change the BackColor property to a different color. Be sure to select a color from the Standard Colors set.
  9. Click Apply.
You should notice that only two of the four controls changed color though you would have expected all of them to change.
