<p><font face="Arial"><a name="Usage"></a><font color="#000000" size="5"><strong>Usage</strong></font></font></p>
<p><font face="Arial">To use CHttpDownloadDlg in your project simply include
HttpDownloadDlg.cpp/h from
the test application in your application and #include "HttpDownloadDlg.h" in whichever
files you want to use the class in. You should also copy over all the
"IDS_HTTPDOWNLOAD_.." string resources, the IDD_HTTPDOWNLOAD dialog
resource and the IDR_HTTPDOWNLOAD_ANIMATION "avi" resource. To bring up the dialog to download a
specific file, just use some code like the following:</font></p>
<p><font face="Arial"> CHttpDownloadDlg dlg;<br>
dlg.m_sURLToDownload = _T("http://www.some-site.com/somefile.ext");<br>
dlg.m_sFileToDownloadInto = _T("c:\\somfile.ext");<br>
if (dlg.DoModal() == IDOK)<br>
AfxMessageBox("File was downloaded successfully");</font></p>
<p> </p>
<p><font face="Arial">You should also have a look at the CInetDownloadDlg::OnDownload()
code in the sample application.</font></p>
