Rick,

>>The first one's easy... Where can I find a summary of information on VB data types?<

You probably mean OleDb data types. For OleDb, simply look up "OleDbType enumeration" in the help.

>>The second one is easy too... but it's more wordy...

Nope, not quite so easy. <g> I'm not sure which Access data types map to OleDb data types (since I've never used Access). As a SWAG, I'm guessing that maybe your integer type might be wrong, like maybe you need OleDbType.BigInt or OleDbType.SmallInt instead of OleDbType.Integer. One way to tell for sure might be to write your DataSet out to XML and see how the various columns get represented. This *may* tell you which data types you're using.
