If dlgLogin is your own class, just implement a property containing the user
ID as entered by the user.
So in the dlgLogin form something like,
public string UserID
{
get
{
return (UserIDInputControl).Text;
}
}

Then in the login method, read it like
userID = oform.UserID;

Is that what you're looking for?

Hi,

You can declare a property in the dlgLogin class that contain the userID ,
you will have to check if the login was not succesful and something about
it.

Cheers,

Use this sample code:


namespace App.UI
{
public class FormLogin : System.Windows.Forms.Form
{
private System.Windows.Forms.Button button_Accept;
private System.Windows.Forms.Button button_Cancel;
private System.Windows.Forms.TextBox UserID;
private System.Windows.Forms.TextBox Password;

#region Windows Form Designer generated code
...
#endregion

public static DialogResult ShowDialog(out string UserID, out string
Password, IWin32Window owner)
{
DialogResult ret;
FormLogin frm = new FormLogin();
ret = frm.ShowDialog(owner);
UserID = frm.UserID.Text;
Password = frm.Password.Text;
return ret;
}

public static DialogResult ShowDialog(out string UserID, out string
Password)
{
DialogResult ret;
FormLogin frm = new FormLogin();
ret = frm.ShowDialog();
UserID = frm.UserID.Text;
Password = frm.Password.Text;
return ret;
}
}
}
