PPT: How to Use the AddLine Method

MORE INFORMATION

The AddLine method uses the following syntax: NOTE: The data type for all AddLine parameters is single.

AddLine Parameters

The AddLine method has four parameters:

   BeginX    The X coordinate (in points) for the starting point of the
             line. The coordinate is relative to the top left corner of the
             slide.

   BeginY    The Y coordinate (in points) for the starting point of the
             line. The coordinate is relative to the top left corner of
             the slide.

   EndX      The X coordinate (in points) for the ending point of the
             line. The position is relative to the bottom left corner of
             the slide.

   EndY      The Y coordinate (in points) for the ending point of the
             line. The position is relative to the bottom left corner of
             the slide.
				

Creating Lines

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The following sample Visual Basic procedure draws a horizontal line across the middle of the first slide in a presentation.

Sub DrawHorizontalLine()

      Dim longHeight As Long
      Dim longWidth As Long

      ' Get the slide height and width.
      longHeight = ActivePresentation.PageSetup.SlideHeight
      longWidth = ActivePresentation.PageSetup.SlideWidth

      With ActivePresentation.Slides(1).Shapes

         ' Create the line.
         .AddLine 0, (longHeight \ 2), longWidth, (longHeight \ 2)

      End With

   End Sub
				

The following sample Visual Basic procedure draws a vertical line down the middle of the first slide in a presentation.

   Sub DrawVerticalLine()

      Dim longHeight As Long
      Dim longWidth As Long

      ' Get the slide height and width.
      longHeight = ActivePresentation.PageSetup.SlideHeight
      longWidth = ActivePresentation.PageSetup.SlideWidth

      With ActivePresentation.Slides(1).Shapes

         ' Create the line.
         .AddLine (longWidth \ 2), 0, (longWidth \ 2), longHeight

      End With

   End Sub
				

The following sample Visual Basic procedure draws two diagonal lines. The diagonal lines form an X on the first slide in a presentation.

    Sub DrawDiagonalLines()

      Dim longHeight As Long
      Dim longWidth As Long

      ' Get the slide height and width.
      longHeight = ActivePresentation.PageSetup.SlideHeight
      longWidth = ActivePresentation.PageSetup.SlideWidth

      With ActivePresentation.Slides(1).Shapes

         ' Create line from top left to bottom right.
         .AddLine 0, 0, longWidth, longHeight

         ' Create line from top right to bottom left.
         .AddLine longWidth, 0, 0, longHeight

      End With

   End Sub

				

Using the Return Value

The AddLine method returns a reference to a shape that you created. You can use the reference to modify the properties of the line.

The following sample Visual Basic procedure uses the return value to change the line color and weight.

Sub ChangeLineColor()

      Dim longHeight As Long
      Dim longWidth As Long

      Dim MyLine As Shape

      ' Get the slide height and width.
      longHeight = ActivePresentation.PageSetup.SlideHeight
      longWidth = ActivePresentation.PageSetup.SlideWidth

      With ActivePresentation.Slides(1).Shapes

         ' Get the return value and create the line.
         Set MyLine = .AddLine(100, 100, 300, 100)

         ' Change line weight to 50 point.
         MyLine.Line.Weight = 50

         ' Change line color to red.
         MyLine.Line.ForeColor.RGB = RGB(255, 0, 0)

      End With

   End Sub

				

NOTE: Because the AddLine method returns an object, use the Set command to get the returned shape reference.
