例子

VBA：

Sub Example_OLEQuality()
    ' This example reads and modifies the preference value that controls
    ' the plot quality of OLE objects. When finished, this example resets
    ' the preference value back to its original value.
    
    Dim ACADPref As AcadPreferencesOutput
    Dim originalValue As Variant, DisplayValue As String
    
    ' Get the output preferences object
    Set ACADPref = ThisDrawing.Application.preferences.Output
    
    ' Store original value
    originalValue = ACADPref.OLEQuality
    
    ' Read and display the original value
    GoSub GETVALUE
    MsgBox "The OLEQuality preference is currently set to: " & DisplayValue

    ' Modify the OLEQuality preference by changing it to High Quality Photographic
    ACADPref.OLEQuality = acOQHighPhoto
    GoSub GETVALUE
    MsgBox "The OLEQuality preference has been set to: " & DisplayValue

    ' Reset the preference back to its original value
    '
    ' * Note: Comment out this last section to leave the change to
    '         this preference in effect
    ACADPref.OLEQuality = originalValue
    GoSub GETVALUE
    MsgBox "The OLEQuality preference was reset back to: " & DisplayValue

    Exit Sub
    
GETVALUE:
    ' Convert the value of this setting to a meaningful text string
    DisplayValue = ACADPref.OLEQuality
    Select Case DisplayValue
        Case acOQLineArt: DisplayValue = "Line Art"
        Case acOQText: DisplayValue = "Text"
        Case acOQGraphics: DisplayValue = "Graphics"
        Case acOQPhoto: DisplayValue = "Photo"
