blank session variables return  

I have a couple of session string variables.

In some cases they will be empty strings and I want them to return an empty string but they return   (non breaking space). Is there some quick way, may be a built in function to convert the   to and empty string (without an if statement)

You didn't say what you were programming in. I'll assume VB.Net:

Code:

---

  Dim regEx, str1              ' Create variables.
  sessionStr1 = "& nbsp;"
  Set regEx = New RegExp            ' Create regular expression.
  regEx.Pattern = "& nbsp;"          ' Set pattern.
  regEx.IgnoreCase = True            ' Make case insensitive.

  'Once the above is set up, you should be able to do the following repeatedly
  ReplaceTest = regEx.Replace(sessionStr1, "")  ' Make replacement.

---

The above uses regular expressions which some might argue is overkill. Perhaps, but if you don't know about regular expressions, and you want to gain a competitive edge, learning about them now will definitely help. In a nutshell, regular expressions let you do wildcard matching of strings in wild ways.

I'm more curious to know why or how your strings are returning &nbsp?

Any session variables I use as strings I always test against String.Empty on the code behind:

VB Code:

If me.Session.Item(0) = String.Empty ...

After looking back at my code I found out why it was happening.

I am setting the value of the session variable with the value in a datagrid cell. As the database field is null it is defaulting to   at bind time.

I have however made a note of string.empty and now use that, thanks nemaroller.
