Im curious about the WDABASE class...i want to write my own for SQL server....there doesnt seem to be much in the book about the WDABase class....it just kind of shows up

See Appendix B

Great! thanks!

Why are the datatable and dataset objects passed byRef instead of byVal in the FillDatatable and FillDataSet methods of the WDABase class?

Please review pages 147 and 148 and let me know if you still have questions.

thanks for the quick reply....i havent had a chance to look at pgs 147,148 but will here as soon as i ask this question...

in the addparameter method the parameter type is passed in as oledbtype...

i am assuming type refers to the type of parameter that is being added (e.g. integer, string)

am i correct in assuming this?
what does it mean for sqldbtype to be an enumeration as compared to other data types or variables... can you enlighten me a bit more on this please?
thanks so much

I think I may have answered my own question on the sqldbtype enumerated type

by declaring or passing it as that type (sqldbtype) will allow only certain values to be accepted (all the values listed for sqldbtype ..bit,int,text,datetime, etc)

an error will be thrown if a value that is not a member of the sqldbtype ....correct?

You are correct in your assumptions. Enjoy!
