Connection Strings And a log in form?

[andycharger]

Hi guys,

 

A couple of questions in one post. Sorry about that......

 

1) Connection Strings.....

When im building a windows Application in dot net, I want to add a connectionstring into my app so that I do not have to keep making the connection everytime I call it. Like when you set a connectionstring in the global.asax file in web application. Firstly, is this possible and secondly can someone provide an example?

 

2) Log in form.

 

I have built one but is there a template type one somewhere. Basically, when i log in, I want to store the user_id somewhere so I can say Welcome user_id when I log in.

 

Any help is appreciated as always.
