.NET Forum / Languages / VB.NET / March 2008Should be a really easy if statement
I need to evaluate the context of a textbox to see if it already contains a period. if it does then exit sub, else do this code. If me.txtbox.text contains a period then exit sub else code... end if Is there some sort of function for this? Something like a contains(me.txtbox.text,".") I hope this makes sense.

One way to proceed with this sort of question would be to start typing: If me.txtbox.text. At that point Intellisense will show you what methods are available. Maybe you can see something that looks like it might do what you want. Another approach is to realize that me.txtbox.text is a String, and go look at the properties and methods of the string class. I prefer Google for this rather than the built-in help. Googling for: .NET string class will probably show the MSDN documentation for the String class in the first few hits. Jonathan, AFAIK is mostly this used to see if something exist in a string if MyString.IndexOf(0,".") = -1 then 'there is no dot. (you can concatinate that and find as well the second dot.

I'm going to suggest INSTR, merely because it is actually BASIC.
