I am implementing a system where the user can Reset their password if they have forgotten it.Once it is reset I want to give them the option of changing the password so that it will be something more memorable to them.The password is hashed and if i enter in the correct old password and new password the password does change.If I enter in the wrong old password and new password the password doesnt change.Is there a way to match the old password with the old password field in code behind so I can throw up an error to the user to tell them what is wrong?

I'm trying to create a password change form for my company's vendors. There are a couple of scenarios I could encounter doing this:
1 - User enters invalid current password 2 - New passwords do not match 3 - User's account is locked 4 - User cannot authenticate because password is expired
It's case 4 that I'm struggling with, because their is no way for me to take the password the user entered and verify it against active directory without getting an error.
I am looking to create a simple password box that will ask the user for a username and pass, if the user is validated against the usernames and passwords in an .ini file the login box will close and launch a program also stated in the .ini file. I would also like to be able to launch different programs for different users.
I am working on a registration form and it requires to put in password that's atleast 6 characters long but shouldn't be more than 15. And contains atleast one number.
How do I write code to check if the user have met the requirements or not?
I have a textbox that acts as a password field. It is supposed to contain a value at least 8 characters long and not greater than 12 characters in length.

I have created my own virtural keyboard for a touch screen interface. I used two forms,one for the main program and one for my keyboard so the keyboard will have opacity of 90%.in my main program form's login screen, i have two textboxs, one for username one for password. the password is a textbox with UseSystemPasswordChar property set to True.I used the technique descripted here: How to: Simulate Mouse and Keyboard Events in Code to send a keycode to different form window.
1. get window handler using FindWindow() 2. set main program form as focused window by SetForgoundWindow() 3. then sendkeys.send(keycodes)
it worked perfectly when i try to input letters to the username by the virtual keyboard, but it not really working for the password textbox.Strange when i set the password textbox 's UseSystemPasswordChar to False again it worked. if i put my virtual keyboard as one of the controls of my main program form it also works but i then don't have the opacity property for my keyboard. of course, in this case the Findwindow() and setforgroundwindow() is not needed.

I am writing a program which allows me to log in to my favorite forum, and displays me my fav. threads, and automatically refreshes current thread every 30 seconds or so.For this, I first need to login to the forum page. Fortunately, the forum allows to login during posting a new message, and it's a public forum so browsing threads is possible without login. Therefore I can directly jump to the "edit article" page without login, fill in login information and write the post, and then send it altogether. Here is an example link for that:
