Target Invocation Error

Hello all, I have developed my project in the following environment ( VB.NET) Microsoft development environment - 2002 Microsoft .net framework - 1.0.3705 Backend - Sql Server 2000 In my project i'm experiencing exception throw "Exception has been thrown by the target of an invocation". I don't know when will it occur and not occuring often. Whenever i'm using my application for more hours this error is thrown. When i'm in search of this error in google i found some different answers:- 1. FIX: "Exception has been thrown by the target of an invocation" error message when you deserialize an empty TimeSpan class in a DataSet collection in a .NET Framework application. 2. FIX: "Exception has been thrown by the target of an invocation" error message when you try to deserialize data that has a value of Byte[0] in an application that was built on the .NET Framework 1.0. but i'm not using any serialization method in my project to serialize objects. I'm totaly confused and i'm not able to pin point the cause for this kind of error!!!!!! Need help urgent Thanx in advance, Lword

The cause is that somewhere in your data stream you have a datetime field with either invalid data or is not typed properly. You may or may not realize it, but data is being serialized all the time, even if only to move from memory allocation to memory allocation. If you're not being given a line number reference then you'll have to set a breakpoint somewhere where the error is likely to occur and narrow it down from there.
