I have a check box in my form that I need to define along with other fields for inserting data. But I am not sure How to define it for inserting data. Below is my code.
cmd.Parameters.AddWithValue("#EmailTmp", (txtEmail.Text));
cmd.Parameters.AddWithValue("#PhoneTmp", (txtPhone.Text));
cmd.Parameters.AddWithValue("#AgreeTmp", (cbAgree.CheckBox));
Looking at your pasted code, I think you want this:
cmd.Parameters.AddWithValue("#AgreeTmp", (cbAgree.Checked));
or possibly something like:
cmd.Parameters.AddWithValue("#AgreeTmp", (cbAgree.Checked ? 1 : 0));
cmd.Parameters.AddWithValue("#AgreeTmp", (cbAgree.Checked));
This will give you a boolean value of true if checked, false if not. SQL will translate this into a 0/1 if you have the field in the SQL db as a bit.
Edit: As a side note, you don't need the "#" in front of the AgreeTmp

I dont know how to use regex ,i have seen them to be used in email validation ,Is there any way i could restrict null values by using regular expression
/^(.+)$/
This regex will match anything which isn't empty (require one or more character), but is it really usefull to check it with a regex ?
The answer is no. null is not a value. It indicates you that the pointer doesn't point to anything. You can use "assert", or just if(yourobject==null){}

In my online course I'm asked to put a label (lblQuestion with accelerator) and ComboBox on a form.
Putting a label and a combo box on a form is simple enough in VS 2010, but I am not sure what an accelerator is and how I use it?
For setting an accelerator you will use & character in front of the letter of your label, that you need to make available as an accelerator. See here: http://blog.csharphelper.com/2012/05/30/use-accelerators-on-labels-and-buttons-in-c.aspx for more details.

Does C# have a code that makes a prompt box appear so that you can insert a value on it?
Like a messageBox but with a text field, like the one that javaScript has.
Or do I have to create a form for it?
You can use InputBox method from VisualBasic Interaction class.

I am fetching data from database and i am showing it in multiple select box but i want to show location 1,3,5 items should be selected by default. How?
Bind the Listbox to the datasource. A google search will probably be helpful.
If you mean "how do I select specific items", then this so question will help.
In WPF, you can use the ListBox control.

How would you go about sending key commands or keypresses of particular keys in C#, specifically numbers.
For instance I would like to simulate typing "512" programatically.
Possibly Related: C# SendKeys.Send
If you would use inputsimulator you could just do:
var number = 2011;
InputSimulator.SimulateTextEntry(number.ToString());
An integer variable doesn't have a UI, so can't have a keypress.
Events are for visual objects, not for variables
