DataSet Select

[lothos123452000]

I have written a VB.NET application and filled a dataset with information. I need to select Distinct Rows from the dataset based on a column in a table in the dataset. How can I do this? I know the dataset has a select property but I do not understand how I can get to use the select distinct query against this dataset. Please help and as always any help offered is greatly appreciated. Also I need to set this count to a variable, I then need to update a row in the dataset so I can feed it to crystal report i.e set the reportsource to this dataset.
