URGENT!!! How to detect whether a value is convertible or not using the Cxxx()

[sorinvoinea]

...functions?

They only give error messages if they are given non-numeric parameters.

Also, using IsNumeric() doesn't work. I have a value like "0,30,0,35" and obviosly it can not be converted to any numeric type.

Thanks.

I am sure there is a question in there somewhere, but I'll be blowed if I can see it.

With that and the strident URGENCY!!! of your subjects means that you are in danger of destroying any goodwill towards you sunshine. People won't even bother trying to answer your posts.

the question is in the subject... I appologize... continued with the word "functions" in the messag body. I hope it's clear now.

SOOORRRRYYYYY

Yeah man, the urgency thing is super annoying...
If its that urgent, go buy some books or pay a consultant.

However, I think I understand what you are asking, and I was just thinking about this the other day. I think the answer is to build a function that uses error trapping/surpression, just like the classic "workbook open" function:

WorkBookOpen(WorkBookName as string) as boolean

Basically, just use the function and check for an error. For something like Cstr that has different error conditions, you could use a Select Case.

How about

=ISNUMBER(--D1)

I presume you are only talking about the numeric conversion functions? You could try using Val instead, or in conjunction.
