Windev : “Null” Value in DataBase
I have a problem with Null Value.
I Explain. Here is the below code :
ChnToto is a chain
ChnToto = Null
On debugging, we find that Windev has stored a "0" (zero) in "ChnToto".
I totally lose the initial information (=> "Null").
How to force the compiler to keep this information without having to use the "Variant" type?
I feel that you have to go through a complex variable, or a class.
Thanks for your advices or ideas

You must use the variant type if you want to handle the null value.
In windev the string type handle 0 and null the same way.
