[FAQ's: OD] How do I change the drawing layout and/or page size?

Changing the drawing layout from Portrait to Landscape or Landscape to Portrait is allot different in Visio then other Office Apps. Same for changing the drawing size too. Its objects are organized differently and a bit burried down the object heirarchy.


Visio 2003 VBA Code Example:

VB Code:

Option Explicit
'Behind ThisDocument
'Note: Assumes current open drawing is "Drawing1.vsd"
Private Sub ChangeLayout()
    Application.Documents("Drawing1.vsd").Pages(1).PageSheet.CellsSRC(visSectionObject, _
    visRowPrintProperties, visPrintPropertiesPageOrientation).FormulaU = "2"
End Sub
 
Private Sub ChangePageSize(ByVal strWidth As String, ByVal strHeight As String)
    Application.Documents("Drawing1.vsd").Pages(1).PageSheet.CellsSRC(visSectionObject, _
    visRowPage, visPageWidth).FormulaU = "11 in"
    Application.Documents("Drawing1.vsd").Pages(1).PageSheet.CellsSRC(visSectionObject, _
    visRowPage, visPageHeight).FormulaU = "8.5 in"
End Sub

VB Code:

'Example Usage:
Private Sub Command1_Click()
    ChangeLayout
End Sub
 
Private Sub Command2_Click()
    ChangePageSize "11 in", 8.5 in"
End Sub

Visio 2003 And VB 6 Code Example:

VB Code:

Option Explicit
'Add a reference to Microsoft Visio xx.0 Object Library
Private moApp As Visio.Application
Private moVsd As Visio.Document
Private moVsp As Visio.Page
 
Private Sub cmdApply_Click()
    'Change the drawing layout according to the option button selection made by the user
    If optLandscape.Value = True Then
        moVsp.PageSheet.CellsSRC(visSectionObject, visRowPrintProperties, visPrintPropertiesPageOrientation).FormulaU = "2"
    Else
        moVsp.PageSheet.CellsSRC(visSectionObject, visRowPrintProperties, visPrintPropertiesPageOrientation).FormulaU = "1"
    End If
    'Change the drawing size according to the users input
    '(need to do more error checking but this is just for an ex.)
    If Len(txtWidth.Text) > 0 And Len(txtHeight.Text) > 0 Then
        moVsp.PageSheet.CellsSRC(visSectionObject, visRowPage, visPageWidth).FormulaU = txtWidth.Text & " in"
        moVsp.PageSheet.CellsSRC(visSectionObject, visRowPage, visPageHeight).FormulaU = txtHeight.Text & " in"
    End If
End Sub
 
Private Sub cmdOpen_Click()
    Set moVsd = moApp.Documents.Open("C:\Development\Tips\Visio FAQ - Page Layout and Size\Drawing1.vsd")
    moApp.Visible = True
    Set moVsp = moVsd.Pages.Item(1)
    cmdApply.Enabled = True
End Sub
 
Private Sub Form_Load()
    Set moApp = New Visio.Application
    moApp.Visible = False
    optLandscape.Value = True
    cmdApply.Enabled = False
End Sub
 
Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
    Set moVsp = Nothing
    moVsd.Close
    Set moVsd = Nothing
    moApp.Quit
    Set moApp = Nothing
End Sub
