InsideHeight Property [Access 2003 VBA Language Reference]

You can use the InsideHeight property (along with the InsideWidth property) to determine the height and width (in twips) of the window containing a form. Read/write Long.


expression Required. An expression that returns one of the objects in the Applies To list.


The InsideHeight and InsideWidth properties are available only by using a macro or Visual Basic and can be set at any time.

If you want to determine the interior dimensions of the form itself, you use the Width property to determine the form width and the sum of the heights of the form's visible sections to determine its height (the Height property applies only to form sections, not to forms). The interior of a form is the region inside the form, excluding the scroll bars and the record selectors.

You can also use the WindowHeight and WindowWidth properties to determine the height and width of the window containing a form.

If a window is maximized, setting these properties doesn't have any effect until the window is restored to its normal size.


The following example shows how to use the InsideHeight and InsideWidth properties to compare the inside height and width of a form with the height and width of the form's window. If the window's dimensions don't equal the size of the form, then the window is resized to match the form's height and width.

Sub ResetWindowSize(frm As Form)
    Dim intWindowHeight As Integer
    Dim intWindowWidth As Integer
    Dim intTotalFormHeight As Integer
    Dim intTotalFormWidth As Integer
    Dim intHeightHeader As Integer
    Dim intHeightDetail As Integer
    Dim intHeightFooter As Integer

    ' Determine form's height.
    intHeightHeader = frm.Section(acHeader).Height
    intHeightDetail = frm.Section(acDetail).Height
    intHeightFooter = frm.Section(acFooter).Height
    intTotalFormHeight = intHeightHeader _
        + intHeightDetail + intHeightFooter
    ' Determine form's width.
    intTotalFormWidth = frm.Width
    ' Determine window's height and width.
    intWindowHeight = frm.InsideHeight
    intWindowWidth = frm.InsideWidth

    If intWindowWidth <> intTotalFormWidth Then
        frm.InsideWidth = intTotalFormWidth
    End If
    If intWindowHeight <> intTotalFormHeight Then
        frm.InsideHeight = intTotalFormHeight
    End If
End Sub
