lol i made it

but i will try your recommended solution now and tell you what i did
Here is the solution [NOTE : dont need to change modifiers to Public just keep it Private]
In the iWebWrap (the login check class)
Code:
public string username;
public string password;
public void login()
{
if (username == "admin" && password == "admin")
{
MessageBox.Show("Worked !");
}
else
{
MessageBox.Show("Wrong ID or PW");
}
}
In the OptimumMain (Which is the main GUI class)
when login button clicked
Code:
iWebWrap ir = new iWebWrap();
ir.username = txtWebUser.Text;
ir.password = txtWebPass.Text;
ir.login();
MoepMeep tell me what is your openion about what i did [note i did not changed the modifier its private as it is]
Also there is a small question that not relevant to programming when i am designing the UI i some times want to hide something (not from the real program but from preview in visual studio so i can add somethings behind it without moving )
