## WebQueryConnection class

Specifies the properties for a web query source. A web query will retrieve data from HTML tables, and can also supply HTTP "Get" parameters to be processed by the web server in generating the HTML by including the parameters and parameter elements.

```csharp
public class WebQueryConnection : ExternalConnection
