Add the following to your CMainFrame

///////
// ADD INTO YOUR CMainFrame HEADER FILE:
///////

afx_msg LRESULT OnMyProgress(WPARAM wParam, LPARAM lParam);

//////////
// ADD INTO YOUR CMainFrame MESSAGE MAP
/////////
ON_MESSAGE(WM_INC_PROGRESS,OnMyProgress)
ON_MESSAGE(WM_START_ANIMATION,OnStartAnimation)


//////////
// ADD INTO YOUR CMainFrame CPP file
/////////
LRESULT void CMainFrame::OnMyProgress(WPARAM wParam, LPARAM lParam)
{
int iPercent = (int)wParam;

if(100 == iPercent && IsAnimationActive())
{
StopAnimation();
}
else
{
// Update visuals here perhaps to reflect percentage of completion
}

Return Value

Returns nonzero if successful, or zero otherwise.

To retrieve extended error information, call GetLastError.

CString CDropEdit::ExpandShortcut(CString &inFile)
{
    CString outFile;

    // Make sure we have a path
    ASSERT(inFile != _T(""));

    IShellLink* psl;
    HRESULT hres;
    LPTSTR lpsz = inFile.GetBuffer(MAX_PATH);

    // Create instance for shell link
    hres = ::CoCreateInstance(CLSID_ShellLink, NULL, CLSCTX_INPROC_SERVER, IID_IShellLink, (LPVOID*) &psl);

    if (SUCCEEDED(hres))
    {
        // Get a pointer to the persist file interface
        IPersistFile* ppf;

        hres = psl->QueryInterface(IID_IPersistFile, (LPVOID*) &ppf);
        if (SUCCEEDED(hres))
        {
            // Make sure it's ANSI
            WORD wsz[MAX_PATH];
            ::MultiByteToWideChar(CP_ACP, 0, lpsz, -1, wsz, MAX_PATH);

            // Load shortcut
            hres = ppf->Load(wsz, STGM_READ);

            if (SUCCEEDED(hres)) 
			{
				WIN32_FIND_DATA wfd;

				// find the path from that
				HRESULT hres = psl->GetPath(outFile.GetBuffer(MAX_PATH), 
								MAX_PATH,
								&wfd, 
								SLGP_UNCPRIORITY);

				outFile.ReleaseBuffer();
            }

            ppf->Release();
        }

        psl->Release();
    }

	inFile.ReleaseBuffer();

	// if this fails, outFile == ""
    return outFile;
}
