vb.net splash screen invoke error

Hi,

I have a splash screen in my vb.net app, when I install the program on other computers, I randomly get this error right after the splash screen: ".net framework Unhandled exception : invoke or beginInvoke cannot be called on a control until the window handle has been created."

I know this error is associated to the splash screen because when I bypass it the error never occurs. I've tried some solutions online regarding this issue but I can't seem to get it working.

Thanks for the help

You probably have some code in Load event of the main form which may need to be moved to Shown event instead.

How is your splash screen displayed?  Are you using the default mechanism thru Project --> Properties?...or are you doing it manually?

Hi,

Yes, I'm using the the default mechanism through Project --> Properties

Here's the code in my load event on my main form, the splash screen has absolutely no code in the load event :

        prjAccessData = New project
        prjManagDataSet = prjAccessData.getPrjAccessDataSet
        prjManagBindingsource = New BindingSource

        prjbudgetData = New project
        prjbudgetDataSet = prjbudgetData.getPrjbudgetDataSet
        prjBudgetBindingsource = New BindingSource

        hoursData = New project
        hoursDataSet = hoursData.getHoursDataSet
        hoursBindingsource = New BindingSource

        With prjManagBindingsource
            .DataSource = prjManagDataSet
            .DataMember = "projets"
        End With

        With hoursBindingsource
            .DataSource = hoursDataSet
            .DataMember = "FeuillesDeTemps"
        End With

        With prjBudgetBindingsource
            .DataSource = prjbudgetDataSet
            .DataMember = "budget"
        End With

        Label4.DataBindings.Add("text", prjManagBindingsource, "prjNumber")
        Label5.DataBindings.Add("text", prjManagBindingsource, "Mandats")
        Label7.DataBindings.Add("text", prjManagBindingsource, "prjAddr")
        Label8.DataBindings.Add("text", prjManagBindingsource, "cliName")
        Label9.DataBindings.Add("text", prjManagBindingsource, "prjContact")

        TabControl1.SelectedIndex = 2
        TabControl1.SelectedIndex = 1
        TabControl1.SelectedIndex = 0

        heuresTotal.DataBindings.Add("text", prjBudgetBindingsource, "heuresTotal")
        chargeTxt.DataBindings.Add("text", prjBudgetBindingsource, "bossHours")
        revTxt.DataBindings.Add("text", prjBudgetBindingsource, "revHours")
        dessTxt.DataBindings.Add("text", prjBudgetBindingsource, "dessHours")
        directTxt.DataBindings.Add("text", prjBudgetBindingsource, "directHours")
        techTxt.DataBindings.Add("text", prjBudgetBindingsource, "techHours")
        rechNotesTxt.DataBindings.Add("text", prjBudgetBindingsource, "notes")

        forageTxt.DataBindings.Add("Text", prjBudgetBindingsource, "forage", True, DataSourceUpdateMode.OnValidation, 0, "C")
        analTxt.DataBindings.Add("Text", prjBudgetBindingsource, "analyse", True, DataSourceUpdateMode.OnValidation, 0, "C")
        TextBox4.DataBindings.Add("Text", prjBudgetBindingsource, "recherche", True, DataSourceUpdateMode.OnValidation, 0, "C")

        Thread.CurrentThread.CurrentCulture = New CultureInfo("en-US", False)
        FeuillesDeTempsDataGridView.AllowUserToAddRows = False

        'Check if the computer is assigned :
        If My.Settings.empName = "" Then
            If MessageBox.Show("There is no Employee assigned to this workstation, would you like to assign one now?", "Feuille De Temps", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button1) = Windows.Forms.DialogResult.Yes Then
                Form4.ShowDialog()
            Else
                Me.Close()
            End If
        Else
            ' if it is assigned then load up the employee information : 
            empName = My.Settings.empName
            Me.Text = My.Settings.empName
            Me.EmployeesTableAdapter1.FillBy(NCLDataSet.Employees, empName)
            empRate = NCLDataSet.Employees.Rows(0)(2)
        End If
     

Open in new window

I suspect it may be line 58

Me.Close()

You are closing current form before it even has finished loading. I would suggest you move all this code to Shown event which would also make you main form appear quicker (as it would show up quickly).
