Title: NetWebClient._CallPageReceived - Am I causing this problem?
Post by: GFasolt on February 05, 2009, 08:30:04 AM

Using NetWebClient to get a small file file from a server (http://proentry4.com/web/PROENTRY4.wud). This is causing consistent crashes, which have led me to NetXxx.clw.

In NetWebClient._CallPageReceived:
loc:tempLen = Len(Clip(self._LastURLRequested))
where loc:tempLen is set to 0

Next
if self._LastURLRequested[loc:tempLen] = '/'...

Obviously 0 is a problem here.

What might I be doing wrong to cause this?

Hi Greg,

First off - your server is case sensitive. The file you're fetching is
www.proentry4.com/Web/PROENTRY4.wud
not
www.proentry4.com/web/PROENTRY4.wud

Second the error. It's a little bizarre because the property self._LastURLRequested does not appear to actually be _set_ anywhere, and so the code in that routine is clearly a bug - or there's a bug somewhere, I'm not sure yet.

But most of all that code only runs if ServerResponse > 300 <= 399. Which it doesn't seem to be. Your server returns 200. 

So all in all it's a very inconsistent report.

Use the netdemo program (netweb client procedure) and see what happens from there.

Cheers
Bruce

Hi Bruce,

Thanks for your reply.

The case was correct in my code, soory about the link.

The error was definitely in the 300 range.

I tested with the demo and no problems. Upon returning to my app - as of my most recent testing with no changes in the area involved - there is no error at all.

I have no explanation so I'll just keep my eyes open.
