Convert text to double

Hello

I want to convert a value in a text propertie to a double.

I can use CDbl(grid1.text) for this, but the problem is that some text
properties are empty and when they are the code give errors.

Is there a way to convert text to double, but if the text is empty he just
returns zero?

Kind Regards
Erwin

Cdbl(Val(grid1.text)), but watch out it will give zero for an empty
string. Otherwise use if ..then

if lenb(grid1.text) <> 0 then
CDbl(grid1.text)
end if

B.

val(text1.text)
- I believe it returns zero if empty or not a number

re: Convert text to double

The best way would be to handle the error in the code. Use the 'On Local
Error' trap to handle it within the subroutine. If you get the conversion
error you can do whatever makes sense to your application.
