I've got an IF statement that validates data. Basically looks like this:
[Code]...
But if I do this I've got the same error message twice and I believe it's less clear what my intent is. I've also tried throwing parenthesis around the s Is Nothing clause, but it doesn't work. Is there an elegant what to test if the object is nothing and then test a property of it?
I am creating a custom config section that will allow me to manage what ELMAH exceptions I want to ignore from my VB.NET/ASP.NET app. Here's my code. I made it easy to paste in a blank code file if anyone's up to the challenge of diagnosing the problem.
CODE:
When I execute this code:

What boggles my mind is that this all works fine in my C# console test app after I convert the code from VB.NET using a web utility. However, when I paste the VB code from my web app into my VB.NET console test app, it doesn't work there, either, so it appears to be a C#/VB issue. What am I doing wrong here?

The problem, The INSERT statement works fine in the form load but not in the button click event?
I was convinced that If <expression> Then <statement [:statement]> Else [statements] in concrete form of If a = b Then SayHello() Else SayBye() End has sense. I read article on msdn on If-then-else, but I forgot why I was reading, so I concluded, that snippet above means this
If a = b Then HelloIsSaid : IsNotEnded Else ByeIsSaid : IsEnded But I have tested it now, and I see, that Else without statement is nothing more than decoration. It would be pretty good if it had function I described. Do you think its good request? Or do you know any circumstance where this Else has some function?

View 2 RepliesBasically what it does is - you can mark a section of the screen and it creates a preview window for that section and keeps it on top of all other windows. I want to make a similar thing, for 3 reasons: 1. I can't use third party software in my office PC, 2.I can't afford it, 3. It will be an immense pleasure to create something useful, which I can share with the community.So, I was wondering, what would be the way to go about it.se dot net (probably VB.net)make a frameless windowet it to stay on topcreate a context menu to exit

I have a splitcontainer on my form and a listview in the right split section. I maximize the form on load, and have problems widening the splitcontainer to fix the width of the maximized form and not cutting off the scrollbar. I don't want to dock inside the form because I have buttons I want to put above the splitcontainer. The amount that is cut off by the edge of the screen seems to vary by resolution. So I need to find a way to make this a dynamic solution.
