Declaring variables from class

[harrysk]

Hello, Ive got the following problem: I don't know how to create a NEW member everytime i click the button. I've got: Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click Dim Mem1 As New Member Mem1.Title = Me.cmbTitle.Text Mem1.Forename = Me.tbForename.Text Mem1.Surname = Me.tbSurname.Text Mem1.Address = Me.tbAddress.Text Mem1.Town = Me.tbTown.Text Mem1.Postcode = Me.tbPostcode.Text Mem1.DateOfBirth = Me.tbDob.Text Mem1.Telephone = Me.tbNumber.Text Mem1.CustomerID = Me.tbID.Text End Sub But it doesn't create anew member each time?????:(( Any help will be much appreciated.

Of course not. All you did was create a Member object, called it Mem1, set a bunch of properties on it, then forgot about when the Sub finished. What are you trying to save this object in? You don't have any code in here to save the object anywhere. You need to store the object somewhere, like in a collection, that was created outside this function you posted. Currently, the Member object you created only exists inside this function. For instance, if you wanted to create a new TextBox control on a form you could:

Private Sub btnNewTextBox_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNewTextBox.Click
Dim myNewTextBox As New TextBox
myNewTextBox.Text = "Some text..."
End Sub

Just like you did with your Member object. But, you'll never see this TextBox to be able to do anything with it because at the end of the function, the new object is detroyed because nothing outside this function can get to it. What you need to do is add it to a collection that was created outside this function. In my example, its the form's Controls collection:

Private Sub btnNewTextBox_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNewTextBox.Click
Dim myNewTextBox As New TextBox
myNewTextBox.Text = "Some text..."
Me.Controls.Add(myNewTextBox)
End Sub

Same thing. Create the new member and add it to a collection that's been created outside the function your creating the new member in. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome
