how to close a form correctly

[pooky]

Public Class frmDataInput1
    
    Private Sub frmDataInput1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        'Display Form Title
        Me.Text = "Hasselburg Tie " & frmStartUp.CmbTieSize.Text & " Data Input"

        'Closes Form Startup
        frmStartUp.Close()
    End Sub
End Class

The first User form that appears is Start up form. This is where the user picks the product type. Depending on the product type selected, will determine the user form that opens next. In this case, form Data Input 1 opens. What I need to see happen is that when the user selects the product from the start up and opens the designated form it should then close the Start up form and leave open the frmDataInput1. However, that does not occur. When I select the product that would use this form it opens it up and closes it when the form start up closes. But if I change frmStartUp.Close() to frmStartUp.Hide() , it then does what I want it to do. I don't want to have more than one form open in memory. Is there a way to fix this? thanks

in your vb menus:

Project-->Properties-->Shutdown Mode-->When last form closes

Its little difficult to understand what you are trying to achieve.
But Do you want that when the user select the product so the desired form will open and the current form closes? is it what you want?

The first form that appears is the startup form. Once the user selects the product from that startup userform. The startup form closes and opens the form that corresponds to the selected product. I am running visual studio 2012. .Paul, when I went to my program's properties, I did not seem anything in regards to Shutdown mode. Thanks to both of you for your help.

Add a line of code to our code, after
frmStartup.close

Correspondingform.show

sorry, try:

Project-->Properties-->Application-->Shutdown Mode-->When last form closes

it's definitely there (I checked all versions from 2008-13)...

also you need to open the new form before closing the first form. as 'when last form closes' implies, it will end the application as soon as there are no forms open
