System.OutOfMemoryException and PreRenderRecursiveInternal

[Jones]

Hello,

I've been searching through a lot of posts on these subjects, but none
of them seem to pertain to what I'm seeing. I've got a C# Asp.net app
which never really pulls back a lot of rows, but I'm now getting this
out of memory exception. I'm getting all my data from a web service.
Initially I built the web service and had it as part of my project and
everything was working fine. I would call the web service and return
a dataset and then use that dataset to fill grids etc., pretty
standard stuff. The problem started happening when I decided that I
should make my webservice standalone, so that when I had to make
changes to it, I could update my webservice, without affecting my
original project. Then what I did was include the web service dll as
a reference so I could still get Datasets back from the webservice.
At this point I started getting the System.OutOfMemoryException
error. The call stack then references the PreRenderRecursiveInternal
method about 5 times, so I was wondering if this was getting into a
repeating loop, thus causing the memory error?? I'm not sure either
if by making a reference to the web service dll, if this is the proper
way to do that or not.

Any thoughts or comments on this would be appreciated.

Thanks,

Gary Jones

OK- isn't it funny how you post to these groups and then before anyone
responds, you typically figure it out already. I guess that's a good
thing!

Well- in this case what happened was when I created the standalone web
service I changed the name of the [WebService(Namespace="xx")]. I
don't really understand why, but when I changed it back to the
original name, everything worked. I'll look into that now.
