Question save info

[pjfatboy]

Hi all, I'm still pretty new to vb.net. In vb 6 I was able to save info to a Microsoft access database with this code...

I'm trying to do this is vb.net but I get this error... "[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified". I guess my question is, am I able to use this same code in .net? If so could someone tell me what is causing this error?

If you're going to use VB.NET then use it, which means using ADO.NET for data access rather than ADO. Here are some ADO.NET code examples for common scenarios:

Retrieving and Saving Data in Databases

Thanks jmcilhinney, yeah I want to use vb.net that is why I ask. Your examples helped a lot thanks.

I guess I need to explain what I am trying to do. I have a DataGrid with 12 Columns and 31 Rows. Not only does the DataGrid display data but it has some formatting to it that needs to be saved. The formatting involves cell background color and text color. That is why I don't think data binding would work.

Also SqlConnection is underlined on line two.

 

[jmcilhinney]

Like all types, SqlConnection is a member of a namespace. Like all types, you must either qualify the name with the namespace or import the namespace.

Data-binding will work for the data itself but not the meta-data, so you should add code for just that and use binding for the rest.
