>Ok, but i need find a programatic way for do it. Declare const is a solution, but, exist several ADO objects with this datatypes...

There are a large number of them; I don't have a file containing them to give you, perhaps someone else does, so that you can simply use the declarations vi #INCLUDE. Someone has to construct the list in the format you want. You could also do the work and post it here on UT so other people could use it...
