To check an empty string into a variable

How can I check an empty string into a variable?

For instance, I want to check if the 'Var2' is equal to empty string (I mean nothing):

Code:

---

If ((Var1 = 7) AND (Var2 = "")) Then
        value.IsValid = False
        Exit Sub
End If

---

In this way (Var 2= "") doesn' t run

Thanks,

You could do Len(var2) = 0

.Length method of string type is the pure .NET way if you want to do it that way . Len is imported from Microsoft.VisualBasic which is only for compatiblity support .

It does the same :( . I don' t understand why? The 'Var2' is a text field in an aspx web form page.

If I put this, runs:

Code:

---

...
If ((Var1 = 7) AND (Var2 = 2)) Then
        value.IsValid = False
        Exit Sub
End If
...

---

But I want to check an empty string to 'Var2'...

Any suggestions?

thanks Pirate.

Didn't know that, I will use .length instead.

I don't understand this neither , try removing the round brackets and replace 'And' for 'AndAlso' . See if this makes any difference .

It does the same.. The normal way is (Var2 = "") when the object that represents 'Var2' is an asp.net text box?
