posted November 20, 2005 10:37 AM i think the error line is http1.get(orderform) if i try to run the pagefetch app i get the following error: An unhandled exception of type 'System.InvalidCastException' occurred in PageFetch.exe Additional information: De opgegeven conversie is ongeldig. (in english: the given conversion is invalid) in vb.net the following line got yellow: Dim comE As System.Runtime.InteropServices.COMException = ex |

posted November 20, 2005 12:40 PM I need to know exactly which line the error occurs on. Please step through the code or turn off exception handling to determine this. Also, please tell me what version of Visual Studio you are using. |
