As Mod: This thread is a discussion about tutorials but more about tutorial you would like to see.
So if there is one you would like to see add it, and another member could write it.

[jcremeans11]

I'd like to see a tutorial that shows how to make your app interface and control other programs, such as an internet block does to internet explorer.

[glenn3095]

If you would like to see a certain topic covered in VB.Net post your request or suggestion here. The tutorial, more than likely, wont be written the instant you post your suggestion but someone will work on it for you.

I would love to see a tute on using Data Grid Views. Setting these things up is driving me nuts.
Thanks.

Hello. I looked on the site and didnt seem to find anything on this so hopefully you havnt allready touched on it and Im just being ignorant. It is a simple matter anyway but I am very new to VB and would appreciate the help.

Basically, I am working on a project which requires a login system. Now the system may be simple ans straight forward, but I am looking for discretionary marks and have dont some research on an advanced login system.

I was able to get what I want. A login system with a create account side to it, whereby a folder with users is created. It is working perfectly but I was only able to do this while both login and create account pages were on the same form, either side by side or on different tabs. I however wish to make form 1 have the login, with a create new account button, which will take me to form 2, which will hold the create account GUI. I tried to do that, didnt seem to be much harder, but after creating the account, form 1, the login form, does not find the folder with the account although i seem to have clearly showed it where it is and put in the variables to read it.

I am getting long-winded here so I will post the code I curently have setup, and will ask if you could possibly make a tutorial on how to create an advanced login system on 2 forms as I have described. Thanks

here is my code on the login system:


Create Account button - form2(user gets here by clicking create acc button on form1 :

CODE

  Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCreateAcc.Click
        If My.Computer.FileSystem.DirectoryExists("C:\Accounts\") Then

        Else

            MkDir("C:\Accounts\")

        End If

        If My.Computer.FileSystem.DirectoryExists("C\Accounts\" + txtUserChoice.Text) Then
            MsgBox("Error - Account allready exists")
        Else
            MkDir("C:\Accounts\" + txtUserChoice.Text)
            Dim a As New System.IO.StreamWriter("C\Accounts\" + txtUserChoice.Text + "\Username.txt")
            a.WriteLine(txtUserChoice.Text)
            a.Close()

            Dim b As New System.IO.StreamWriter("C\Accounts\" + txtUserChoice.Text + "\Password.txt")
            b.WriteLine(txtPassChoice.Text)
            b.Close()

            MsgBox("Account Created. You may now login")
            frmLogin.Show()
            Me.Hide()



        End If
    End Sub

and the login button on form 1, which reappears after user presses create button:

CODE

Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click
        Try

            Dim sa As String
            Dim sb As String

            Dim a As New System.IO.StreamReader("C:\Accounts\" + txtUsername.Text + "\Username.txt")
            sa = a.ReadLine()
            a.Close()

            Dim b As New System.IO.StreamReader("C:\Accounts\" + txtUsername.Text + "\Password.txt")
            sb = b.ReadLine()
            b.Close()

            If txtUsername.Text = sa.ToString Then
                If txtPassword.Text = sb.ToString Then
                    MsgBox("Welcome -" + sa.ToString)

                Else
                    MsgBox("Error - Password Incorrect, please try again")

                End If
            Else

                MsgBox("Error - Account does not exist")

            End If




        Catch ex As Exception

            MsgBox("Error - " + ex.Message)


        End Try
    End Sub

Note that i used the try and catch way, although there was an alternative, but I wish to use the try and catch as we recently touched on it and it would be good if I used it.

You need to use the phrase "static" instead of "dim"

[D00M]

You mean change every single variable to static or just the ones that read the files? Or?

[jcremeans11]

well, it depends on how you want to use each on. If you want the information to be used on that one open form, then thrown out, use dim. If you want to keep the information throughout the rest of the program, use static. Also, you need to save your accounts to a database. There are a few tutorials in here that demonstrate how to do that.

[D00M]

Yes I was thincking about that. A later part of my project will require a data base aswell ,so I was going to look into how to work with that. Thanks, I will try to adjust the variables, and get the database working as soon as I get the grips of it.

Hey guys, where are in the Request a Tutorial section.

Whats happening here is actually a post for the vb.net forum itself and not the tutorials request section.....

[Donnie1581]

I would like to request an extensive tutorial on using multiple user-defined classes, object instantiation, and WithEvents. I've been over the tutorials that talk a little about classes and objects but they didn't have enough detail for me to grasp.

My final project for Intermediate to Visual Basic was suppose to use a form class, an account class, and transaction class with triggered events. It turned out to be a disaster and now I'm like lost in the dark and have no clue on how it should have been done correctly.

My professor wasn't too helpful; I went the whole term getting full points on all my projects, then we cover OOP in about a week which was nowhere enough time to fully understand how to use objects of classA inside classB and send it to the form for display.

I would love to see a quick tutorial on how to get the number of Gmail messages in my Gmail account. This will probably use POP3.
