Yes, you can use Valentina DB ADK and Valentina Reports ADK with a Standard Edition of Xojo/REALbasic, if you disable RBDB API dependency.

Please read HOW TO here: installation.

You can write the following code, which allow you handle Valentina exceptions separetly from any other exceptions:

SomeFunction()
   ...
 
Exception err as VException
   MsgBox "Valentina throw exception: " + Str(err.ErrorNumber) + ":" + err.Message
 
Exception err
    MsgBox "Error!"
end

Class VException is child of Exception class of REALBasic. This means that you can also write code as in the next example and still catch Valentina exceptions.

SomeFunction()
   ...
 
Exception err
    MsgBox "Error!"
end

Yes, exists difference. In the first case works VField.value as VARIANT, In the second case works VLong.value as integer. The second case is much faster, at least for RB 5.5 - 2006.

You need to use the “self” keyword of REALbasic to get reference of the current Table.

You can use method VField.SetBlank().
Also you can use property VField.IsNull = true.
