Jorge,

Yeah, that'll work just fine, although you'll more than likely data-bind a text object on your form to the data objects columns, so you won't actually need to assign the text box's value to the DataSet's columns. You can do that in the property sheet or in code. Oh yeah, I forgot you're not using the IDE. Hmmm ... well then, I guess you'll need to data-bind in code. There's examples in various help stuff on how to do that.

>Hi Bonnie, I'm using only the free download of the SDK for now, I don't think that's available to me, unless there's something like a command line utility. C# for about $100 (even less for ugrades) seems like a bargain, so I should pick it up soon. But thanks, I'll keep it in mind for when I have the full IDE.

Another option when using DataSets is to >have .NET generate a typed dataset for you (right click in your .xsd >and click on the Generate option). The syntax is easier to handle. >Your example would then be:
