Do you have a sample code? You can't set plot device name using GetPlotDeviceList, you have to use SetPlotConfigurationName method from the plot validator like that:
acPlSetVdr.SetPlotConfigurationName(acPlSet, PlotSettingsToUse.PlotConfigurationName, strCanonicalMediaName)
where acPlSet is the plotsettings object copy from the PlotSettingsToUse object.
Before you have to be sure that the plotconfigurationname exist and the CanonicalMediaName too.
Plotting is a complex task, many things can go wrong: paper size, plotting device, pc hardware, etc, add a very poor documentation and you got the figure. I would try first with the examples in the Kean's blog, like this:Plot a Window , for example check out the comment on the window definition and the order to code it. Show your code, platform, etc. as it's very hard to guess what can be wrong.
' Changes the plot settings for a layout directly
Public Sub ChangeLayoutPlotSettings()
' Get the current document and database, and start a transaction
Dim acDoc As Document = Application.DocumentManager.MdiActiveDocument
Dim acCurDb As Database = acDoc.Database
Using acTrans As Transaction = acCurDb.TransactionManager.StartTransaction()
' Reference the Layout Manager
Dim acLayoutMgr As LayoutManager = LayoutManager.Current
' Get the current layout and output its name in the Command Line window
Dim acLayout As Layout = _
' Output the name of the current layout and its device
acDoc.Editor.WriteMessage(vbLf & "Current layout: " & acLayout.LayoutName)
acDoc.Editor.WriteMessage(vbLf & "Current device name: " & acLayout.PlotConfigurationName)
' Get a copy of the PlotSettings from the layout
Using acPlSet As PlotSettings = New PlotSettings(acLayout.ModelType)
' Update the PlotConfigurationName property of the PlotSettings object
Dim acPlSetVdr As PlotSettingsValidator = PlotSettingsValidator.Current
acPlSetVdr.SetPlotConfigurationName(acPlSet, "DWG To PDF.pc3", "ANSI_B_(11.00_x_17.00_Inches)")
acPlSetVdr.SetPlotConfigurationName(acPlSet, "DocuPrint 3100", "A3 (297x420mm)")
' Zoom to show the whole paper
' Update the layout
' Output the name of the new device assigned to the layout
acDoc.Editor.WriteMessage(vbLf & "New device name: " & acLayout.PlotConfigurationName)
' Save the new objects to the database
' Update the display
acPlSetVdr.SetPlotConfigurationName(acPlSet, "DWG To PDF.pc3", "ANSI_B_(11.00_x_17.00_Inches) ")
Then I do not have any problem,
Of print environment using in us
acPlSetVdr.SetPlotConfigurationName(acPlSet, "DocuPrint 3100 ", "A3 (297x420mm) ")
When I carry out
By einvalidinput error, a command is terminated abnormally.
When I carry this out,
Current device name: DocuPrint 3100
Because I appear, must be a Device name.
Please teach a cause, measures.
Thanking you in advance.
Please run this Kean's code, and you will see correct plot device names and cannonical media names of your system.
Maybe you mistyped some of this two names in your code.
