ScaleTop Property

You can use the ScaleTop property to specify the units for the vertical coordinates that describe the location of the top edge of a page when the Circle, Line, Pset, or Print method is used while a report is previewed, printed, or its output is saved to a file. Read / write Single.

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

Remarks

You can set the ScaleTop property by using a macro or a Visual Basic event procedure specified by a section's OnPrint property setting.

By using these properties and the related ScaleHeight and ScaleWidth properties, you can set up a custom coordinate system with both positive and negative coordinates. All four of these Scale properties interact with the ScaleMode property in the following ways:

• Setting any other Scale property to any value automatically sets the ScaleMode property to 0.
  
  
• Setting the ScaleMode property to a number greater than 0 changes the ScaleHeight and ScaleWidth property settings to the new unit of measurement and sets the ScaleLeft and ScaleTop properties to 0. Also, the CurrentX and CurrentY property settings change to reflect the new coordinates of the current point.

You can also use the Scale method to set the ScaleHeight, ScaleWidth, ScaleLeft, and ScaleTop properties in one statement.

Note   The ScaleTop property isn't the same as the Top property.

Example

The following example uses the Circle method to draw a circle and create a pie slice within the circle. Then it uses the FillColor and FillStyle properties to color the pie slice red. It also draws a line from the upper left to the center of the circle.

To try this example in Microsoft Access, create a new report. Set the OnPrint property of the Detail section to [Event Procedure]. Enter the following code in the report's module, then switch to Print Preview.

Private Sub Detail_Print(Cancel As Integer, PrintCount As Integer)

    Dim sngHCtr As Single
    Dim sngVCtr As Single

    Dim sngEnd As Single

    sngHCtr = Me.ScaleWidth / 2               ' Horizontal center.
    sngVCtr = Me.ScaleHeight / 2              ' Vertical center.
    sngRadius = Me.ScaleHeight / 3            ' Circle radius.

    Dim sngWidth As Single, sngHeight As Single

    Me.ScaleMode = 3                          ' Set scale to pixels.
    sngTop = Me.ScaleTop                      ' Top inside edge.
    sngLeft = Me.ScaleLeft                    ' Left inside edge.
    sngWidth = Me.ScaleWidth / 2              ' Width inside edge.
    sngHeight = Me.ScaleHeight / 2            ' Height inside edge.
    intColor = RGB(255, 0, 0)                 ' Make color red.

    ' Draw line.
    Me.Line (sngTop, sngLeft)-(sngWidth, sngHeight), intColor
