ScaleLeft Property [Access 2003 VBA Language Reference]
You can use the ScaleLeft property to specify the units for the horizontal coordinates that describe the location of the left 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.
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 ScaleLeft property isn't the same as the Left property.
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) Const conPI = 3.14159265359 Dim sngHCtr As Single Dim sngVCtr As Single Dim sngRadius As Single Dim sngStart As Single Dim sngEnd As Single sngHCtr = Me.ScaleWidth / 2 ' Horizontal center. sngVCtr = Me.ScaleHeight / 2 ' Vertical center. sngRadius = Me.ScaleHeight / 3 ' Circle radius. Me.Circle (sngHCtr, sngVCtr), sngRadius ' Draw circle. sngStart = -0.00000001 ' Start of pie slice. sngEnd = -2 * conPI / 3 ' End of pie slice. Me.FillColor = RGB(255, 0, 0) ' Color pie slice red.

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