[2005] For-Each statements - How To Extract Data From Dataset -
Well, I've been googling all morning to no avail.
I'm new to ado.net and foreach statements, but I've managed to extract the data from my database and fill a dataset (used a datagridview to clarify that the recordset wasn't empty).
Now I'm trying to work out how to either extract the data from the dataset, or how to easily manipulate and use it while it's in the dataset.
If anyone could explain basically how to use foreach statements, or some relatively simple way to either extract the data from the datasets or manipulate and use it while it's in there, it would be much appreciated. I've been searching for hours..
BTW, I'm using OleDB (Access) with ado.net and visual basic 2005.
Thanks in advance.
