You need to do as the error message says - pass the value in with the 'ref' keyword in front of it. 

var someResult = String.Empty;

ServiceReference1.nwebserviceClient req = new ServiceReference1.nwebserviceClient(); 
req.aaCheck(username.Text, password.Text, ref someReult);

Then you can do what you want with someResult.

So your web service seems to expect a ref string as third parameter. Guessing from the parameter name probably to return some result. The following will work:

string resultDesc = "";
req.aaCheck(username.Text, password.Text, ref resultDesc);
label.Text = resultDesc;
