What's the best way to do this

[Guest]

Hi,
What's the best way to check if two or more textboxes are empty before
executing a task?

I have the foll which is NOT WORKING

If Not (txtDateFrom.Text Is Nothing) And (txtDateTo.Text Is Nothing) Then


.....DO THIS

Else

.....Do that

End If

Thanks

If Not (txtDateFrom.Text Is Nothing) And (txtDateTo.Text Is Nothing) Then

If (txtDateFrom.Text <> "") And (txtDateTo.Text <> "") Then

or

If (txtDateFrom.Text <> String.Empty) And (txtDateTo.Text <> String.Empty)
Then

Chris,
Mark is correct. testing against Nothing will never be true, but Text
could be an empty string. Use String.Empty rather than "". Using ""
allocates a new string object, but string.Empty uses a global instance of
string that is 0-length. This will save just a little bit of memory.
