I have created two applications in VB.net - each periodically (every minute or so) downloads an xml file and further processes items contained within the XML into an SQL database. When run singularly (i.e. only one app running at a time) the program operates normally, but when attempting to run an incidence of each app at the same time, one programme is freezing at xml download [hangs at XMLHTTP.send()] whilst the other seems to run normally.
I am running the following code in each program:
XMLHTTP.open("GET", htmladdr, False)
Catch ex As Exception
How come this is happenning? For over three years I have executed a similar task for around twenty other URL locations, but they all post csv text files instead of XML- I have not experienced any problems and I run twenty of the little suckers on one machine. What is the trick with XML?
