How to remove sidebar while incorporating Gogle maps into a windows form app?

You'd have to create your own web page that integrates a map, and browse to that. It can then contain js.

I've done that. Now how do i talk to the map? What i mean is, in the original code
queryAddress.Append("http://maps.google.com/maps?q=");
i'm using a text box called "textcity" where the user has to enter the name of the city to be shown, and a button called "btnMap" upon whose click the respective city should be shown. The following code elaborates this.
string city = string.Empty;
city = txtCity.Text.Replace(' ', '+');
queryAddress.Append(city + ',' + '+');

This works only if the main address is "http://maps.google.com/maps?q=".

But now, on your advice, i've integrated google maps into a web page "http://sraanishanth.awardspace.us".
But for this address, the above method doesn't work. When i click the buttton, the explorer throws a 404 error. Please tell me what i have to do.
Forgive me if my questions seem too silly, but i have little knowledge and only now i have started learning.

Yes, you are right. I shall start looking up the documentation. Thank you for your patience.
