>Put a breakpoint in at the start of the loop and it will fire up the .NET debugger. then you can cycle through the lines of code at your leisure. To insert a breakpoint, click the margin to the left-hand side of your code and a little red circle should appear. This is the line of code that will execute first in the debugger

TVM. However, I have another problem which prevents me from doing this? I have to fire up my app in VS.NET with CTRL F5, rather than F5. I think this means that I miss the bit that you suggested. However, if I start the app with F5, I get the following error in a dialog:

Error while trying to run project: Unable to start debugging on the web server. The web server has been locked down and is blocking the DEBUG verb, which is required to enable debugging.

>This also works for WebServices. You can put a breakpoint in your code and run it. Then, call the webservice, using the internet explorer page or externally from VFP for example, and it will open the debugger at that point. This last bit is marvellous and has saved me from grey hair many a time :)

Sounds good if I can get the above sorted out.
