FIX: AFX_IDC_MAGNIFY Cursor Fails to Load from AFXDLL

 * }

Q113532

1.00 WINDOWS kbprg kbfixlist kbbuglist -- The information in this article applies to: - The Microsoft Foundation Classes (MFC), included with: - Microsoft Visual C++ for Windows, version 1.0 -- SYMPTOMS ======== When using the File Print Preview capabilities of the Microsoft Foundation Classes (MFC), the mouse cursor disappears when dragged over a view when the application is in Print Preview mode. This behavior occurs only when the AFX_IDC_MAGNIFY cursor resource is moved from the application to an extension (_AFXDLL) DLL. CAUSE ===== The problem occurs in the CPreviewView::OnSetCursor function. Line 904 of the VIEWPREV.CPP file, below m_hMagnifyCursor = ::LoadCursor(AfxGetInstanceHandle, MAKEINTRESOURCE(AFX_IDC_MAGNIFY)); should be m_hMagnifyCursor = ::LoadCursor(AfxGetResourceHandle, MAKEINTRESOURCE(AFX_IDC_MAGNIFY)); STATUS ====== Microsoft has confirmed this to be a problem in the Microsoft Foundation Classes for Windows version 2.0. This problem was corrected in the Microsoft Foundation Classes version 2.5. MORE INFORMATION ================ AfxGetInstanceHandle always returns the HINSTANCE of the application. AfxGetResourceHandle first checks the application for the resource; if it isn't found, AfxGetResourceHandle walks through each of the extension dynamic-link libraries (DLLs) to find the resource. For additional information concerning AfxGetResourceHandle, please consult the Microsoft Foundation Classes Technical Note #33.
