Hide MainForm when LoginForm is called?












0















I have 2 forms, 1 Login form and the other is the Main Application Form.



The Main Form launches Login Form since auth = false, the issue is though since I am calling the login from the main application how do I then hide the main form when the login form is shown and then display the mainform once the user is authenticated?



This is my Main App call:

    You could simply use ShowDialog() instead of Show()

  • @FlatEric that seems to do the trick, what would i need to do to recall or pass the dialog as authenticated? just Close() the dialog?

  • ShowDialog() returns a DialogResult, which you can set in LoginForm before you close it.

  • Creating login forms is a very traditional newbie-to-winforms mistake. Such an app always runs in a session where the user already logged-in using the highly secure Windows login procedure. One that's battle-hardened by being attacked every conceivable way. You are not talking to a complete stranger on the Internet. Putting your own login procedure on top of that is a very significant security risk, users will simply re-use their Windows logon password and the odds that you treat them just as securely as Windows does are very slim. Don't do it.

In MainForm:



LoginForm authForm = new LoginForm();
var result = authForm.ShowDialog();
if (result == DialogResult.OK)
{
// authentication was successful
}


In LoginForm: Set authentication result ok (if if was successful)



DialogResult = DialogResult.OK;

    I think the best way is run login form and main form both from Program.cs file.



    You can change Program.cs file like this:



    namespace YorNameSpace
    {
    public static class Program
    {
    public static DialogResult result;
    [STAThread]
    static void Main()
    {
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);

    using (var loginForm = new loading())

    result=loginForm.ShowDialog();
    if (result == DialogResult.OK)
    {
    // login was successful
    Application.Run(new Main());
    }
    }
    }
    }
