The information in this article applies to:
- Microsoft Visual C++ for Windows, version 1.0
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.
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));
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.
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.
