[RESOLVED] Bypass 1st Form based on My.Settings (conditional)

[SLeePYG72786]

Hey guys / gals. I'm having a little trouble figuring out how to bypass the first form of my program based on the content of a My.Settings... setting.

Details
When the program loads it shows a form that allows you to select the network adapter you wish to monitor.
When you have selected the adapter you click a button (Save), which shows Form1 (main form) and saves the settings.
When Form1 loads it closes NICselect then reloads the settings.

txtAdapters.Text is the property I wish to check.

Problem
The issue is that it gets annoying having to reselect the adapter each time the program is launched, so I wish to check the My.Settings property of a control on NICselect which holds the last selected adapter. I have tried a few times, but I'm still getting the NICselect form on each launch.

Current code

NICselect load:

'Form Load
    Private Sub NICselect_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

        'Need to add My.Settings check to see if the adapter matches the My.Settings setting. If so, skip this form and open Form1.
        'Otherwise, start with this form.
        If My.Settings.txtAdapters <> Nothing Then
            Form1.Show()
            Me.Close()
        Else
            Me.Show()
        End If

Save command for NICselect:

'Save, open Form1, close this form
    Private Sub btnSave_Click(sender As System.Object, e As System.EventArgs) Handles btnSave.Click
        Form1.Show()
        My.Settings.Save()
        perfErrorCatcher.Dispose()
    End Sub

Form1 load

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

        perfNetDown.InstanceName = NICselect.txtAdapters.Text.Replace("/", "_")
        perfNetUp.InstanceName = NICselect.txtAdapters.Text.Replace("/", "_")

        NICselect.Close()

        My.Settings.Reload()

Any and all help contributed would be greatly appreciated. =)

Hi,
im not sure of your question but to set the setting

my.settings.txtAdapters = "something"

and to test you have it there

if my.settings.txtAdaptors <>  "" then
form1.show()
me.close
else
'nothing as already on me
end if

You're going about that all wrong I'm afraid. You selection dialogue shouldn't know anything about the main form. In the project properties, select the main form as the startup form. Handle the Startup event of the application, which is raised before the startup form is created, and display your selection dialogue in there. Let's say that you have a user setting named SelectedNic. Your Startup event handler would look something like this:

If My.Settings.SelectedNic = String.Empty Then
    'No NIC selected yet.
    Using dialogue As New NicSelectionDialogue
        If dialogue.ShowDialog() = DialogResult.Cancel Then
            'No NIC selected so exit app.
            e.Cancel = True
        End If
    End Using
End If

Your dialogue then simply saves the selected NIC to the SelectedNic property and the dialogue will never be shown again.

Thanks for pointing me in the right direction jmcilhinney. I'll now mark this as Resolved.

Here's what I did in case you're interested:

NICselect Load:

Removed what I had before.

Save command for NICselect:

'Save, open Form1, close this form
    Private Sub btnSave_Click(sender As System.Object, e As System.EventArgs) Handles btnSave.Click
        My.Settings.Save()
        Form3.lblCurrentAdapter.Text = txtAdapters.Text.Trim
        perfErrorCatcher.Dispose()
        Form1.Show()
        Me.Close()
    End Sub

Form1 Load:

If My.Settings.txtAdapters = String.Empty Then
            'No NIC selected yet.
            NICselect.Show()
        End If
