  • its a simple as showing the second form using the

    dim x as new form2

    Instead of

    Dim x as new form2


    Try using both of them an calling from an instance of form1 and seeing the difference.

  • I want to pop out the form1 using dialogbox because i want the focus always on the form1 unless they close it. I use the following code but it shows two form under the taskbar and is there any way for me to display the dialogbox with one taskbar form. Thank you.

    Dim DisplayForm As New form1

  • Try setting the TopMost property to true.

  • Sorry, mistyped the code, actually i made use of

    Dim DisplayForm As New form2


    and it still don't work as my requirement. It did pop out the dialogbox but how to make the two taskbar forms to become one? Thank you.

  • There is a potentially easy way round the problem. Show the second form modally (a concept you'll be familiar with from VB.OLD, I'm sure). The .NET syntax is:-

    Private Sub ShowForm2Button_Click(ByVal sender As System.Object_
        ByVal e As System.EventArgsHandles ShowForm2Button.Click
        Dim F2 As New Form2()
    End Sub

    Now, as you'd expect, the user can't get focus back to Form1 to click that pesky button again until they've closed down this instance of Form2.

  • I think lucerias wants there to be no taskbarbutton for the modal form, so try this (with wei82's example):

    Private Sub ShowForm2Button_Click(ByVal sender As System.Object, _
        ByVal e As System.EventArgs) Handles ShowForm2Button.Click
                 Dim F2 As New Form2()
                 F2.ShowInTaskbar = False
    End Sub

  • Is it possible to show the DialogBox and specify it is under one parent as child form at the same time? If it is possible, any one can show the sample code? Thank you.
