[.net] Problem with opening forms

How can i open a new form with .net? In vb6 it's just frmSomeName.Show but that doesn't work in .net.

Anyone?

Dim F As Form = New frmSomeName
F.Show()
:)

Dim F As Form = New frmSomeName
F.Show()
:)

Do you also know how to close a form? Unload(frm2) doesn't seem to work either.

Thanks

f.Close()
or
Me.Close() will close the form. :)

f.Close()
or
Me.Close() will close the form. :)



Private Sub PiOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PiOK.Click

'variablen declaren
Dim frm2 As Form = New VPF1()

frm2.SCOpenen.Enabled = True


It doesn't recognize the SCOpenen in frm2. When i use frm2.Show It opens a copy of form1 and doesn't change anything in the form that's actualy there.

I tried to let it change a label but it didn't do anything

Try
Dim frm2 As VPF1 = New VPF1()
Make sure that VPF1 is the actual name that you give to the form (the name of the form variable there 'frm2' can be anything). :)

VB.Net is quite different from VB6. Forms are not Public in your project and you can't set the values of things on one Form from another Form directly like you could in VB6.

Try
Dim frm2 As VPF1 = New VPF1()
Make sure that VPF1 is the actual name that you give to the form (the name of the form variable there 'frm2' can be anything). :)

This is standing on form 1 called VPF1
on this form i have a menu


Public Class VPF1
Inherits System.Windows.Forms.Form



Private Sub SCInstellen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SCInstellen.Click
Dim oCommSetup As New CommSetup()
oCommSetup.ShowDialog()
oCommSetup = Nothing


End Sub

Private Sub SCOpenen_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SCOpenen.Click
SCSluiten.Enabled = True ' sluiten mogelijk
SCInstellen.Enabled = False ' poort instellen niet meer mogelijk
SCOpenen.Enabled = False ' om niet twee maal te kunnen openen


End Sub

Private Sub SCSluiten_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SCSluiten.Click
SCOpenen.Enabled = False ' Openen niet meer mogelijk
SCInstellen.Enabled = True ' poort instellen mogelijk men moet nu eerst weer OK drukken ?

End Sub





the second form called



Public Class CommSetup
Inherits System.Windows.Forms.Form

' Declare necessary class variables.
Private CommPort As New Rs232()
Private CPort As Integer = 1
Private CBaud As Integer = 9600
Private CPar As Integer = 0 '0=NONE 1=ODD 2=EVEN 3=MARK
Private CDataB As Integer = 8
Private CStopB As Integer = 1



Private Sub PiOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PiOK.Click


If PGCom1.Checked Then CPort = 1
If PGCom2.Checked Then CPort = 2
If PGCom3.Checked Then CPort = 3

If BRG4800.Checked Then CBaud = 4800
If BRG9600.Checked Then CBaud = 9600
If BRG19200.Checked Then CBaud = 19200

If PGNone.Checked Then CPar = 0
If PGOdd.Checked Then CPar = 1
If PGEven.Checked Then CPar = 2

If DBG6.Checked Then CDataB = 6
If DBG7.Checked Then CDataB = 7
If DBG8.Checked Then CDataB = 8

If SBG1.Checked Then CStopB = 1
If SBG15.Checked Then CStopB = 15
If SBG2.Checked Then CStopB = 2


'this is what i want to use here !!!
SCOpenen.Enabled = True


Me.Close()

End Sub


End Class



Maybe u see the problem

I just explained the problem. The first form can't see the members of the second form.

You are going to have to supply a reference to VPF1 via a Public Subroutine, like the 'New' subroutine for CommSetUp.
You need to declare an extra Sub New(ByRef F As Form)
and then, when you set CommSetUp to a new instance, you can pass the VPF1 in as an argument. From there, you can store it in a variable and access it from there. :)
