Connecting A Button And A Text Box In Visual Basic?

I am attempting to connect to Microsoft SQL Server 2008 R2 from within Microsoft Visual Studio 2010. My connection string is as follows:
connection = New SqlConnection("Server=localhost;Database=greenapplication;User ID=WindowsID;Password=WindowsPassword")
I keep getting this exception: System.Data.SqlClient.SqlException:Login failed for user 'WindowsID'.What am I doing wrong? Are there certain permissions that I have to set up?

First let me statethat my VB skills are appalling. Havent touched it since VB3 Ok here is the scenario. we want to be able to give our first line support the ability to modify AD groups BUT WITHOUT giving the acess or powers in the AD console. I have written command line scripts to do this and it works fine. Un fortunately we have people that think that if it dont have a OK NEXT CANCEL button it aint Windows :(

I am a brand new user of MS Visual Basic 2005 Express and MS SQL Server 2005 Express. I have familiarized myself with both programs but have one extremely frustrating problem. Once I open SQL Server, I can not establish a database connection from Visual Basic using the Visual Basic Data Source Configuration Wizard (even if I close SQL Server). If I reboot and open Visual Basic first, I can then connect using the Visual Basic Data Source Configuration Wizard. But then I can not switch to SQL Server and open the database (even if I close Visual Basic). Again, I must reboot to open the database in SQL Server.I suspect there is a setting somewhere that needs to be changed, but I can not find it?

I have to make a calculator for school but I'm in a big dilemma. :( The thing is, I have this calculator with three textboxes and of course digits and operators. There's two input textboxes, txtInput1 and txtInput2 and then there's the buttons from btnZero to btnNine. My operator buttons automatically do the calculation and the output comes in txtDisplay which is disabled (so that you can't write in it).
And the problem is here, I want my btnZero to btnNine move their textvalue to my txtInput1 and txtInput2 as long as they are selected (so the cursor is blinking in it). Now I use "txtInput1 = txtInput1.text & btnZero.text" sure that works, but only for one txtInput. If I can't solve this I'd have to make all the buttons twice. ;( (Edit: If I press my operator button then "txtDisplay.text = (txtInput1 "operator" txtInput2)")

This is what I have so far for the following scenario: I want to have it so that if a users clicks submit without checking a check box from one section it throws up a dialog box that makes the process loop and give them a chance to check a box. The process wont continue until at least one check box is checked. The same thing above goes for my radio buttons as well. Here's my code:
