UpdateCurrentPaper

[FRFR1426]

I change the paper format on a layout with:

PlotSettingsValidator.SetPlotConfigurationName(layout, deviceName, media)

 But the paper doesn't update when I reduce the size (A0 to A1 for example). I've found that I have to call:

plSetVal.SetZoomToPaperOnUpdate(layout, true);
UpdateCurrentPaper(LayoutManager.Current.UnmanagedObject, true);

In order to force the update. AcApLayoutManager::updateCurrentPaper is not exposed in the .NET API, so I had to P/Invoke it. On AutoCAD 2013, I've found it in accore.dll, but I'm not able to found it on AutoCAD 2010. Someone knows where I can found it? Or a workaround? The doc says that the update may be triggered after the call to SetZoomToPaperOnUpdate by a notification, but how to force the sending of this kind of notification without updateCurrentPaper?

Have you tried to call:

Editor.Regen()

Yes, and UpdateScreen too. Only UpdateCurrentPaper seems to work.

It is look like you have to write wrapper (with ObjectARX C++) for this method.

I have used the following code to update the paper size and other properties of a plot settings object for a layout without any problems.  Maybe it will help you.  If not, then the only other option is to P/Invoke the method you mention.  I do remember having some strange issues with getting the paper size to display correctly when I was working on my AU handouts, but did manage to work around it though and did not need to P/Invoke any extra functions.
