Set Current Paperspace Viewport - AutoCAD 2011 x64

I've been using my own implementation of the "Create and enable a floating Viewport" from the AutoCAD 2011 Developer's Guide here, and everything works fine on a 32 bit system, but on 2 different Windows 7 64-bit systems, the following line results in a error:

 

 

//The reason I point this to the specific .exe file is because I have several versions of AutoCAD installed, and I wasn't sure how it knew which one to import the command from.[DllImport("c:\\Program Files\\Autodesk\\AutoCAD 2011\\acad.exe", CallingConvention = CallingConvention.Cdecl,
EntryPoint = "?acedSetCurrentVPort@@YA?AW4ErrorStatus@Acad@@PBVAcDbViewport@@@Z")]
extern static private int acedSetCurrentVPort(IntPtr AcDbVport);

 

 

The error I receive is: 

 

 

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

I guess there must be something I'm missing - the application I'm building works just fine on 32 bit AutoCAD Civil 3D 2009, yet on 64 bit AutoCAD 2011 it fails every time.

I think I might have just fixed this issue myself. After googling the exact error message:

 

"Unable to find an entry point named '?' in DLL"

 

I ended up here: 

 

http://social.msdn.microsoft.com/forums/en-US/csharpgeneral/thread/a96468dc-9426-404e-ace7-0f7a1c8b4...

 

This then pointed me to http://www.dependencywalker.com/

 

After downloading and running this tool on acad.exe I found the function I was looking for.

 

In the attached image you'll see what the correct external call should be.

 

tl;dr: use this:

 

?acedSetCurrentVPort@@YA?AW4ErrorStatus@Acad@@PEBVAcDbViewport@@@Z

 

instead of this: 

?acedSetCurrentVPort@@YA?AW4ErrorStatus@Acad@@PBVAcDbViewport@@@Z

I'm not sure if this affects the 32 bit version of AutoCAD 2011, as I don't have it installed anywhere.

Your solution is 7 years old now, so I was wondering if this is still the only method of setting the current paperspace viewport? If not is there a way to find the location of accore.dll for the version of autocad being used?

Hi,

 

What about using the CVPORT sysvar?

// Set the new viewport current via an imported ObjectARX function the CVPORT system variable
Application.SetSystemVariable("CVPORT", viewport.Number);

In my case, all I've got is viewport objectid. I don't think I can obtain the viewport number from the viewport object. It my exist in the layout object, but I think those numbers are assigned when the layout is open.

It seems to me the layout have to be opened to set current one of its viewport...
