Hi there,
I have the same problem. I have implemented a real time application which update feature attributes every 30 seconds. After 20 iterations, the systen hangs and then I get the same error Cannot Create any more connections to FDO provider. Any help would much appreciated. I have very similar code to Mark's one. regards, Mark Pendergraft wrote: > > Okay, > > > > I have a feature source, which contains quarters of sections..
