I build Log in window where user enter his usernmae and password
I still don"t want use SQL and any data keeper, it's only for two users
so I check the password and username if it' ok than user must press botton OK and load next window this step I can't over .
Are the any suggestions ???
So you hard code your passwords and usernames into your program, this is not very a good idea.
>>and load next window this step I can't over
I think you mean you cannot switch between the login window and the next. Well close the login form and open the main form.
A way to do this is open both forms but call form.Hide() on the main form. Then switch between form.Show() and form.Hide().
