Hi Experts,

I have 2 winforms
Form1 has 1 button... if clicked, it opens form2
Form2 has TabControl1 with xx tab pages...
I want Winform1 button to open winform2 and go direct to TabPage10.

Hope that makes sense?

Thanks,
Roberto

I tried:
Form2.TabControl.SelectedTab = TabPage10

Error Message = "Name 'TabPage10' is not declared"

Couple of errors :(

f2 = Form2 .. Error = 'Form2 is a type and cannot be used as an expression'.

Me.TabControl1... error = 'TabConrtol1' is not a member of 'WindowsApplication.Form1'

Me.TabControl1.SelectedTab = TabPage10 You will put this code in the form load event (the form opened with the button click ...not the form1..The form that contains the tabcontrol)
in the button click event set:

 If f2 Is Nothing Then
            f2 = New Form2
        End If
        If f2.WindowState = FormWindowState.Minimized Then
            f2.WindowState = FormWindowState.Normal
        End If

        f2.StartPosition = FormStartPosition.CenterScreen
        f2.ShowDialog()

Another example:
Public Class Form1



    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim f2 As New Form2

        Form2.Show()

    End Sub



End Class



Public Class Form2



    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Me.TabControl1.SelectedIndex = 9

    End Sub



End Class

Sorry jtoutou,

I cannot follow instructions for toffee ;(

Form 1 - button1 click event =
If f2 Is Nothing Then
            f2 = YourFormNAme
        End If
        If f2.WindowState = FormWindowState.Minimized Then
            f2.WindowState = FormWindowState.Normal
        End If

        f2.StartPosition = FormStartPosition.CenterScreen
        f2.ShowDialog()

Form2 = Load event = Me.TabControl1.SelectedTab = TabPage10

I get an error on Form1 = [f2 = New Form2]
&
[  If f2.WindowState = FormWindowState.Minimized Then]
---error--------------------------------------
An unhandled exception of type 'System.NullReferenceException' occurred in WindowsApplication1.exe

Additional information: Object reference not set to an instance of an object

Either code showed errors, so I combined Idle_Minds code:
 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim f2 As New Form2
        Form2.Show()
    End Sub

with jtoutou's code:
Me.TabControl1.SelectedTab = TabPage10

now it works ;)

Thanks Guys
