Login dialog

[Alejandro Casal]

Hi there,

I'm writing a .net Windows application in C#. I have 2 forms: the MainForm
and the Login. The MainForm opens the Login as Dialog from the MainForm's
constructor, and Login asks for username/password. I get these data from the
MainForm and check using a Web service that they're ok. If username/password
are not ok, I want to close the whole application, but I don't know how
(this.Close() doesn't work). Can I close the app from the MainForm's
constructor? Should I call the Login dialog and web service somewhere else?

Thanks,

Alejandro.

Hello,

If username/password are not ok, I want to close the whole
application, but I don't know how (this.Close() doesn't work).
Can I close the app from the MainForm's constructor? Should
I call the Login dialog and web service somewhere else?

The only way preventing the class from being instantiated is to throw an
exception.

Hi Alejandro,
You may try implement it this way.
1. In Constructor of your MainForm , set the MainForm.Visible = false;
2. In MainForm.On_Load() event handler, show the Login Dialog
and you can call Close() in this handler.
3. if login ok , then set the MainForm.Visible = true;
If you have problem with this, please let me know.
Thanks!
