I'm kind of confused on what you are trying to achieve?  You have a form that "Can't" get focus or you don't want it to get the focus when you load it?  Can you expand on you situation a little bit?

Once you show the form, it can get focus via mouse selection, but you can place event logic in the gotfocus event to shift focus back to another form, if that helps you any.

Try this:

' 1. In the general declaration area of your form (say form2 is the one you don't want focus), add:
Private Declare Function GetForegroundWindow Lib "user32" () As Long

'              2. drop a timer to your form (form2), set the interval to 5 (you can adjust this).
             
               3. In the form2_gotfocus Event, add: Timer1.enabled = True

'              3. in the timer1_timer event, add:
             Timer1.Enabled = false
'            If GetForegroundWindow() = Me.hWnd Then Form1.Show (or what ever form you want focus to be on)
'              This will give away focus in 10 milliseconds

I am assuming you are talking about a Form with the enabled property set to False.

Here's what I tried:

A project with two forms, Form1 and Form2.  A command button on Form1.  Enabled set to False on Form2.

Code in Form2:

Option Explicit

Public Sub ShowMe(frmCalling As Form)
    Me.Show vbModeless
    frmCalling.SetFocus
End Sub

Code in Form1:

Private Sub Command1_Click()
    Form2.ShowMe Me
End Sub

Private Sub Form_Unload(Cancel As Integer)
    Dim i As Integer
   
    For i = 1 To Forms.Count - 1
        If Forms(i).Caption = "Form2" Then
            Unload Form2
        End If
    Next i
End Sub

I'm not sure this is what you want, but what I've basically done is put a method in Form2 that shows itself and returns focus to whatever form wants it opened.  The Unload event in Form1 is clean up to unload Form2 if it has been opened.  If you don't do this, the app won't terminate.

Sorry, I noticed an error in my proposed solution.  In Form_Unload, i should go from 0 to Forms.Count - 1.

I'm not sure what you mean by "flickers".  I noticed that the previous solution allows you to click and momentarily give focus to the window which flashs the title bar from blue to gray.  Didn't notice that on my solution.  But, again, I guess I don't know what "flickers" means.

Check if this helps

Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
Public Const HWND_BOTTOM = 1
Public Const SWP_NOACTIVATE = &H10

Private Sub Form_Paint()
    Me.AutoRedraw = False
    SetWindowPos Me.hwnd, HWND_BOTTOM, 0, Screen.Height / 2, 0, Screen.Width / 2, SWP_NOACTIVATE
    Me.AutoRedraw = True
End Sub
