single quotes inside vb.net string

@Vulpes.

Ya i thought about it, but that would be my last option if i couldnt figure out and fix.

This is a maintenance project and built 8 years back in vb and exception is inside framework which we cant look into.

That's very strange!

What kind of project are you writing and how are you displaying the exception string to the user?

@Vulpes.

My actual code is

Else
                            Throw New Exception("The Following Problem occured:Character ' is Invalid.Please change the name")
                        End If
                        If (lastname.Success) Then
                        Else
                            Throw New Exception("The Following Problem occured:Character ' is Invalid.Please change the name")

But when i try with console application or someother applications, its working with the above string. But in my project for the above code, its coming \'

I just tried this but it worked fine:

   MessageBox.Show("Error User name should not have ' character")

Are you perhaps trying to escape the ' by preceding it with a backslash as you would in C#?

If so, this is unnecessary in VB.NET which doesn't use escape sequences.

Didnt work. if i use \'\, its displaying as \\'\..
