i get error , connection string has not been initialized? what is wrong. I am
sure the answer is simple since I am a newbie!!!!
also, this code i just put on a form , do I need to drag the table on form
and make data set and sql adapter and all that, r should this code work
alone? do I have to bind the text boxes in properties window. be kind, I am
new

You are getting your connection string from AppSettings("DSN") .

Do you have an application configuration file in your project?

If you do - what is the value of the key "DSN" that you are calling
for?

If you don't - check out the System.Configuration stuff in the Docs.

The code you have will work - you do not need to drag a table or
anything else on the form.

I am not sure about the application config file. how would I now, what would
it be called. is there easir way to make connection string. it is simply sql
server db on local machine
