VB .NET - Catch exception for Blank textboxes

[dugdug]

I am looking for a code that will show an error if the textbox is either blank or just filled out with blank spaces.

I'd like the error to be able to stop any further codes from happening?

That is a very simple task, check if the Text property .Trim() is = "". This is a pretty basic concept, so I would recomend checking in with some basic tutorial sites.

if (myTexbox.Text.Trim()=="")
{//its empty
}
