textbox lost focus after popup.show

I

Igor

I'm trying to create a textbox with a dropdown form:

Dim TextBox1 as New TextBox
Dim popup as New ToolStripControlHost
Dim list1 As New ListBox
Dim listhost As ToolStripControlHost

listhost = New ToolStripControlHost(list1)
....
Private Sub TextBox1_TextChanged
popup.Show()
TextBox1.Focus()

Why TextBox1 doesnt recieve focus?

You need to show the window using the SW_SHOWNOACTIVATE message. This can be
done by importing the ShowWindow API via the DllImport method and sowing the
window with the SW_SHOWNOACTIVATE flag (0x04 I believe)
