    check for null-string *resolved*

    Code:
    if not DTR("pro_weight").value is null
Txtweight.text = DTR("pro_weight")
end if

    error is -> BC30822: 'null' is not declared. 'Null' constant is no longer supported; use 'System.DBNull' instead.

    i'm used to programming in vb, and i don't think this can be done this way in vb.net

    what is the way to do it? I'm just checking if the field pro_weight is null or not (since setting Txtweight.text = DTR("pro_weight") where dbfield pro_weight is null will result in an error too...
