Icon problem

Hi
We are storing Icons (.ico) files in our SQL Server Application as type
Image. We have a web service call that returns these through a DataSet and we
write the DataSet to disk using the WriteXML Method on the DataSet object. We
persist them locally for performance issues. When our application loads it
checks a modified date on the table in the DB and determines if it needs to
load them or not. If not, it loads them from the local disk into an ImageList
that the application uses.
Our issue is that our icons are not clean anymore when we do this on certain
areas of our application â€“ some areas they seem to be fine. Iâ€™m not sure if
something is happening to the binary stream in the XML or what, but we need
some help to get our icons looking like they should.
Thanks

Ravi,

When you say icons don't look clean - I assume the picture gets distorted
somehow, or some noise appears on it randomly.

More than certain - this has to do with XML and it's inability to hold
everything.

Instead use your own custom dataobject, and store the icon as a bytearray.
You might need to deploy that dll to the client that uses the webservice,
but hey - thats not such a big deal. Also, try and see if you can use
remoting instead of webservice.
