Re: How to tell if string is missing?

How is strData declared? If it's as a string, the only possibility is a
zero-length string (""), so you'd use
Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/information-technology/9218-how-to-tell-if-string-missing.html

If Len(strData) > 0 Then

If it's declared as a variant, it could also be Null. The simplest check
would then be:

If Len(strData & "") > 0 Then
Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/showthread.php?t=9218

On the odd chance that the string might contain a number of blanks, you
could use the following instead:

If Len(Trim(strData)) > 0 Then

or

If Len(Trim(strData & "")) > 0 Then
