I started to get HRESULT error when trying to solve network dataset in Arc10 programatically. In 9.3, the code works fine. It is in vb.net. In program i added code to release object and garbage collector, but nothing helps.
Sorry for late response. I tried all of your suggestions, but not working. I contacted with ESRI Tech support to take a closer look of my code. Thanks so much for all your help.
