        If My.Settings.Str >= 0 Then
            FrmLogin.Show()
            Me.Close()
        End If

CodePudding user response：

With default project settings, your application will be closed when the startup form is closed. If you want to change this behaviour:

1. Right click on your project in the Solution Explorer
2. Select Properties
3. Select the Application tab
4. Under Shutdown mode, select "When last form closes" (see image below)

Another idea would be to leave the default settings and change your startup form...
