I am an amateur with FoxPro, but I find it very useful, and I developed some code writing skill.

Now I whish to use it to develop Web Page with database management funtionality. I visited many sites (incliding MSDN library), but I am lost. Where can I find beginner clear and simple instructions to develop my web funcionality? Can anyone help me?

Hi Anatoliy

I am looking to send a request for a web page - say, and save the html to a file for data extraction. What is the best way to handle this?

What about HTTPS? Can WinInet handle this?

A simple way is to use URLDownloadToCacheFile call, or its cousin, URLDownloadToFile. Search "RemoteToLocal" in this reference for an example. This API works with HTTP and HTTPS.

Another interesting option is using the MSXML2.ServerXMLHTTP object.

And of course, a solution can be based on each of the API libraries, WinINet, WinHTTP and WinSock. You can find corresponding examples here.
