>>>When communicating with a web page, I am unable to get the values from a GET or POST action method. In C, if you use getenv, you can retrieve QUERY_STRING, and other form variables. You can pass parameters from a web page directly to a C program. You can also send a printf directly to the standard output, these string outputs will be directed to a new web page.

You are actually posting these variables to the web server. The server (IIS, whatever) is then responsible for calling the exe in the URL. If the

>I was looking for a way to do that directly with FoxPro. Rick Strahl in WestWind, uses a DLL. I believe it's written in C. It processes the information and creates an ascii file. Meanwhile, a foxpro app, running in the background has a timer which keeps checking for the existence of a specific file. Once the file is found, the FoxPro app reads in the information and generates a new page.
