    History

    V1.0 (14 November 1999)
    • First public release.

    V1.01 (15 November 1999)

    • Updated documentation to refer to what rc resources are needed by the class.
    • Renamed all resources used from ASYNC_DOWLOAD to include HTTPDOWNLOAD.
    • Now handles HTTP error 407 (Proxy Authentication) and HTTP error 401 (Server Authentication). You are prompted with a password dialog when either of these forms of authentication are required.
    • Sample program now allows you to specify the URL to download from as well as the file to download into and the username and password to connect with.
    • The download file is now deleted if the download was aborted or if some other error occurs during the download.
    • Parsing of URL will now work where "http://" is not explicitely specified.
    • Improved the general look and feel of the demo app and called it "HTML File Downloader".

    V1.02 (29 November 1999)

    • Fixed a number of compiler warnings and errors when used in VC++ 6.0.

    V1.03 (25 January 2000)

    • Fixed a problem where server authentication was not being detected correctly, while proxy authentication was being handled.
    • Updated the way and periodicity certain UI controls are updated during the HTTP download.


    Usage

    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. To bring up the dialog to download a specific file, just use some code like the following:

    CHttpDownloadDlg dlg;
    dlg.m_sURLToDownload = _T("http://www.some-site.com/somefile.ext");
    dlg.m_sFileToDownloadInto = _T("c:\\somfile.ext");
    if (dlg.DoModal() == IDOK)
       AfxMessageBox("File was downloaded successfully");
    

    You should also have a look at the CInetDownloadDlg::OnDownload() code in the sample application.
