How to close sub-form opened by showDialog()?

[Guest]

Hi all,

How to close a sub-form opened by showDialog()?

On the main form, I open a new form by using showDialog().
There is a Timer control on the main form, when Timer.Tick raises, the
program closes the sub-form and main form.
But now, the sub-form cannot be closed and the Me.close() rases error.

Private subForm as Form

Private Sub btnM_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btnM.Click
Dim frm As New Form2(Me)
subForm = frm
frm.ShowDialog()
End Sub

Private Sub Logout(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Timer1.Tick
If Not subForm Is Nothing Then
subForm.Close()
End If
Me.Close()
End Sub

Thanks in advance.

Regards,
Alan

Use subForm.Show instead of ShowDialog. ShowDialog will display the form as
a modal dialog.

Hi,

What is the error message?
Don't forget you must use Invoke to refresh a control from an other
thread than the one created the control.
In C# :
this.Invoke(new EventHandler(delegate
{
this.Close();
}));
