Post Login Screen Help!!!


hey

How can I code a login screen that only allows authorised users access to the programme?

Also I have a Database which will be connected to the login screen so that the users (Username and Password) are stored in the database and the input text boxes will compare with the database records and login successfully.

Thanks

There are an unenumerable amount of examples of answers to this question on this forum and others. The particulars of how each step is implemented are different for every application, but in the end it boils down to this:

Make a login form. Either make that your startup form, or have your main form display it modally. When the user clicks whatever button is the "OK" button, execute something like this:
Code:
If (AreCredentialsValid(username, password)) Then
    MaybeSaveUserInformation()
    ShowMainForm()
    CloseThisForm()
Else
    DisplayErrorMessage()
EndIf
It's up to you to implement the individual steps there. The only snag is, depending on how "CloseThisForm()" is implemented, you might have to change your project settings to close the program when the last form is closed, not the startup form.
