Set Form Height in VBA (1 Viewer)

I apologize if this has already been answered, but I can't find it. I want to specify the height of a continuous form (not modal, not popup, not autocentered) (maybe only the detail section ?) so that it equals the height of what I think is the Access application client area rectangle. I could just maximize the form but sometimes I will have at least 2 forms open at the same time. I don't like using tabbed documents since you can't see more than 1 object at a time. I also use multiple access apps on 3 different sized monitors, and not always with the Access app maximized. Thus I want to get and understand the Access application client area rectangle.

First question: exactly what is the Access app client area rectangle ? My understanding is that it is the area within Access in which I can display objects (tables, forms, macros, queries). Does it include the menu bar, ribbon, database container window, status bar ?

When I use the below code, the form height is too big, so the Access vertical scroll bar appears.

I'm using:
Access Microsoft Access 2016 - Build:16.0.12827 (32 bit)
Windows 10 Pro version 1909 Build 18363 64 bit


Private Declare Function GetClientRect Lib "user32" (ByVal hwnd As Long, lpRect As RECT) As Long

Public Sub WindowSize(ByRef Height As Long, ByRef Width As Long, hwnd As Long, ByRef Top As Long, ByRef Bottom As Long)

'Dim hwnd As Long
Dim rct As RECT

If hwnd = 0 Then
hwnd = FindWindow(vbNullString, "Database1")
If GetClientRect(hwnd, rct) <> 0 Then
'If GetWindowRect(hwnd, rct) <> 0 Then
Height = (rct.Bottom - rct.Top) * TwipsPerPixel("Y")
Width = (rct.Right - rct.Left) * TwipsPerPixel("X")
Bottom = rct.Bottom * TwipsPerPixel("X")
End If
If GetClientRect(hwnd, rct) <> 0 Then
Height = (rct.Bottom - rct.Top) * TwipsPerPixel("Y")
Width = (rct.Right - rct.Left) * TwipsPerPixel("X")
Bottom = rct.Bottom * TwipsPerPixel("Y")
End If
End If
End Sub

Public Function TwipsPerPixel(strDirection As String) As Long

'Handle to device
Dim lngDC As Long
Dim lngPixelsPerInch As Long

Const nTwipsPerInch = 1440

lngDC = GetDC(0)

If (Left$(strDirection, 1) = "X") Then 'Horizontal
lngPixelsPerInch = GetDeviceCaps(lngDC, WU_LOGPIXELSX)
Else 'Vertical
lngPixelsPerInch = GetDeviceCaps(lngDC, WU_LOGPIXELSY)
End If
lngDC = ReleaseDC(0, lngDC)
TwipsPerPixel = nTwipsPerInch / lngPixelsPerInch

End Function

Private Sub buCmd1_Click()'on a form button on click event
Dim intAppWindowHeight As Long
Dim intAppWindowWidth As Long

Dim intFrmWindowHeight As Long
Dim intFrmWindowWidth As Long

intRibbonHeight = Application.CommandBars("Ribbon").Height

WindowSize intAppWindowHeight, intAppWindowWidth, 0

WindowSize intFrmWindowHeight, intFrmWindowWidth, Me.hwnd

'I've tried all the below but the form is always to tall
docmd.movesize 0, 0, , intAppWindowHeight
me.insideHeight = intAppWindowHeight

docmd.movesize 0, 0, , intAppWindowHeight - intRibbonHeight
me.insideHeight = intAppWindowHeight - intRibbonHeight

end sub

I didn't want to get yelled at again, like last time. :)
I do not think there is anything wrong with reporting a cross post. That can save a few responders wasting their time.? :unsure:

I for one, appreciate it and I don't care if the OP ever gets annoyed. If they do, then it's just another one on my list...
