Hello,
How do you set VS 2010 to display the error message when an error is encountered while running your code? Presently when there is an error the form is displayed with no error messages.
Thanks,
Victor

can we get more details? You surely have a Try ... Catch somewhere that silently get rid of the error.
You need to have a label or literal control...some control on your form to actually display the errors.
For example, if you have this in your aspx page
<asp:Label runat="server" Id="msg" />
When there's an error in your form, you do something like this
msg.Text = "There's an error".
You have to trap the error in your code behind.
This is just one way of doing it. You can do it other ways depending on your code.

Eric, you and I posted at the same time. I've been using this method you have for years...for different projects:

Camillia, how do you know it is a web app?
>>Presently when there is an error the form is displayed with no error messages.
Erm - that sounds like my form is showing correctly but there isn't an error. Why does my code work? In other words how do you know there is an error?

Agree Eric. I made an assumption.

Hi,
I am trying to avoid using on error Goto, used to receive error message but not certain what setting was removed.
Thanks.

Unless I am totally mistaken that isn't part of .net in VB.Net error handling possibilities.
What programming language are you using?

@kaufmed for the info.
Thanks - I'm usually code in C++/C# or VBA. (Where there is a goto that is to be avoided if at all possible as a rule of thumb)

Victor, your latest comment doesn't help much. We know it is VB.Net but is it Web, WPF, WinForms, ....?
Do you have Try..Catch that swallow the error?
Do you know the code that you are expecting it to throw an error?

It is a Windows Form.
I am using on error goto instead of try catch.
The error occurs on conn.open.

Thanks, changed to try catch. Do i need to import any files or add anything in reference section? Trying to compare both apps but can't find any differences so far.
no references needed it is part of the core framework
