custom tag. A pointer to an instance of a request object is passed to the main
procedure of a custom tag. The methods available from the request object allow the
custom tag to accomplish its work. For a detailed description of the CFXAPI classes
and members, see the see CFML Reference.
Debugging C++ CFXs
After you configure a debug session, you can run your custom tag from within the
debugger, set breakpoints, single-step, and so on.
On Windows NT
You can easily debug custom tags within the Visual C++ environment. To debug a
tag, open the Build Settings dialog box and click the Debug tab. Set the Executable
for debug session setting to the full path to the ColdFusion Engine (such as,
c:\cfusion\bin\cfserver.exe) and set the program arguments setting to
