    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.

    Thanks for the reply.

    I did finally get the HTML help and got it to work.

    I winded up manually copying all of the resource stuff manually with a text editor.

    I have VS .NET 2003 ... I brought up the sample program, as well as my test dummy program side by side. I tried repeatedly clicking on the resource and dragging it into the other program, but I just can't "automatically" get it to go. It "appears" that it is going to let me drop it, because the arrow turns into an arrow with a box around it, but it never shows up. I've tried "copy" and "paste" as well, but no go.

    As for the library linking. In the passed three months, I have done over 200 examples and read tons of articles on this site (I've spent probably 8-10 hours every day here Big Grin | :-D ). I've read several times, and everyone had something different to say about how to add external resources for linking. Some said what you mentioned, others say it goes as an additional dependency, while others said add it into command line arguments.

    Before using this sample program, I did not ever read anywhere about adding it in as a dependency. I was trying to put it where I read in the command line argument, and error after error came up. When I brought the two projects up side by side, and went through every single option, I finally found the "right" place to put it.

    I thank you for the reply. I did get everything going finally and it works great!
