URLDownloadToFile

[SteveCRM]

Every time I use URLDownloadToFile my program freezes until the transfer is done...I want it to just download, and let the user still do things...

and one other thiing, using URLDownloadToFile how can I get the percent finished?

Thanks

You could probably thread URLDownloadToFile(). The last parameter of that function is a function pointer that you can specify download status.

good idea....thanks

Im not sure how to use that last parameter though

I looked at that post, and realized that the second part made no sense =).

Also, its not a function pointer, as I first thought. Its an Object, that inherits from IBindStatusCallback. Simply implement the OnProgress member function. There is lots of info in the MSDN.

How about using API...

    HINTERNET    hInet=NULL;
    HANDLE        hFile=NULL;
    DWORD        dwByteDownload=0;
    char        Buff[10240];

    // Open a new instance of the Internet Access
    hInet = InternetOpen("MyXML", INTERNET_OPEN_TYPE_DIRECT, NULL, NULL, 0);
    if (hInet != NULL)
    {
        // Access the given URL
        hFile = InternetOpenUrl(hInet, "http://www.yahoo.com", NULL, 0, INTERNET_FLAG_RELOAD, 0);
        if (hFile != NULL)
        {
            memset(Buff, '\0', 10240);
            InternetReadFile(hFile, &Buff, Sz, &dwByteDownload);
        }
    }
    
    // Close all the used handle
    InternetCloseHandle(hInet);
    InternetCloseHandle(hFile);
