So imagine you need the TextBox1.Text inside your thread and since you can NOT access this control from your thread, the value of Textbox1.Text will be NOTHING. which will then raise an error if you … Re: exception has been thrown by the target of an invocation in vb.net 12 Years Ago by bhagawatshinde Hi GeekByChoiCe, This line of code not working .....

Your problem is in the run worker complete part. I don't know what it is. I will look at it later. Add a try catch block in your runworkercomplete sub and put a break point on the catch part or message box the exception. You will probably figure it out. If not post back.

Let me know if any of this information is not correct. Re: Exception has been thrown by the target of an invocation. 12 Years Ago by GeekByChoiCe The problem lays in your BackgroundWorker1_ProgressChanged procedure. You can NOT access controls (which were created in the main thread) from any other thread without using delegates. Check out this thread => [url]http://www.daniweb.com/software-development/vbnet/threads/400426[/url] Same problem + solution. Re: Exception has been thrown by the target of an invocation. 12 Years Ago by Unhnd_Exception [QUOTE=;][/QUOTE] Everything about the above post is wrong. The ProgressChanged event is not even being raised because there is no code in the DoWork event that sets a change. And even if the ProgressChanged was raised you CAN access controls in it. I've already provided the solutions to the problem.
