Display UserName

Dear

You can use Public String Variable to store UseName and after successfully login Disply in veriable value in to label if desktop application you can also use toolstrip menu label to display


best way if you use MDI Form

If I'm not wrong when you are logged in you are hiding the login form when user logged sucessfully. and after that you are opening home page. You can do some on login page

buttonlogin_Click(..)
{
//your logic to check username and pwd
//declare one variable in home page with public modifier

homepage obj=new homepage();
obj.username=textboxusername.Text;
obj.show();
this.hide()
)

may helps you
