password form to perform operation from main form

[ma.giorgi]

Hi Everybody!

I have the following problem:
from the application mainForm the user can do several operation
Some of them are password protected
(the password is a code that change everytime on the basis of a
reference code)

so when the user click on a menu in the main form, the passwordForm is
displayed
the user enter the password and click the OK button

now I have a function in the passwordForm that verify the inserted
password against the reference code
if it's correct I can continue to execute the code in the mainForm
else I stop, to perform this my form should return the result to
mainForm and then close...

I can't figure out how to proceed on this, I mean the logic, I don't
want to use the inputbox from vb.dll, only pure C#.

thanks in advance!

Hi Marco,

If you display your password form using ShowDialog() you can check either
properties on the form directly, or have passwordForm set a DialogResult
before it closes.

//passwordForm
override OnClosing(... ,...)
{
if(ValidateUser)
this.DialogResult = DialogResult.Yes;
else
this.DialogResult = DialogResult.No;
}

//mainForm

if(passwordForm.ShowDialog() == DialogResult.Yes)
{
//User is valid, execute code
}
