How to test if a workbook variable is valid
Hi,
When using a variable of type workbook in an expression, it is necessary to test if its content is valid. For instance that it is not "nothing". However syntaxes like "if wb < nothing then ..." or "if not wb=nothing then ...." do not work. Is there any solution, possibly with a different approach. Thank you in advance. Jean-Pierre B |

Jean-Pierre,
How about IF LEN(VariableName) = 0 (to test for a blank string) Regards Pete "Jean-Pierre Bidon" wrote: Hi, When using a variable of type workbook in an expression, it is necessary to test if its content is valid.

How to test if a workbook variable is valid
Thanks for your help, but the len() function requires an argument of type
string . Actually, I got the answer in the mean time. The syntax I used at first was not good "if wb < nothing then ..." . The right syntax is "if wb is nothing then ...". Thanks. Best regards.

Oops - that'll teach me to read the question properly - it's a bit late in
the day. Sorry Pete "Jean-Pierre Bidon" wrote: Thanks for your help, but the len() function requires an argument of type string . Actually, I got the answer in the mean time.
