Uses reflection to load the assembly and the specified report class; executes, and exports the report.

Assembly is to be specified as the first folder, and report class name as the subfolder. For example: http://localhost/MyAssemblyName/ActiveReport1.ActiveReport where MyAssemblyName.dll is the actual assembly filename, and ActiveReport1 the report class name. The special folder name indicating the assembly is evaluated from right to left, so if there are multiple folder levels, the folder name directly preceding the file name is always the assembly name.

For example, this would allow the following URL to be used: http://localhost/AnyFolder/AnySubFolder/MyAssemblyName/ActiveReport1.ActiveReport

You may also set any parameters you've added to the report's Parameters collection via the DataSource icon in the URL.  For example:

http://localhost/AnyFolder/AnySubFolder/MyAssemblyName/ActiveReport1.ActiveReport?Country=USA
