TrueView 2014 AcCtrl Control

[absStructural]

Has anyone successfully embedded the TrueView 2014 control in a Windows form?  It seems like it shouldn't be all that difficult, but I'm not having much luck.

Hi Michael,

I have attached a sample project that embeds the DWG TrueView ActiveX control and the screenshots to show the steps to use the ActiveX in a .Net project. I have tested this in my Windows 7, 64 bit system that has DWG TrueView 2014 installed.

To try this :

1) Open Visual Studio 2010 64 bit command prompt

2) regsvr32 "C:\Program Files\Autodesk\DWG TrueView 2014\AcCtrl.dll"

3) aximp "C:\Program Files\Autodesk\DWG TrueView 2014\AcCtrl.dll"

4) copy "c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\ACCTRLLib.dll" "C:\Program Files\Autodesk\DWG TrueView 2014\ACCTRLLib.dll"

5) copy "c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\AxACCTRLLib.dll" "C:\Program Files\Autodesk\DWG TrueView 2014\AxACCTRLLib.dll"

6) Add reference to the assemblies in your .Net project from "C:\Program Files\Autodesk\DWG TrueView 2014\ACCTRLLib.dll" and "C:\Program Files\Autodesk\DWG TrueView 2014\AxACCTRLLib.dll"

7) Set the "Embed Interop types" for the assemblies to False as shown in the attached screenshot

8) Build and run the sample. Select a drawing using the Browse button and click on Load button

Sorry, wanted to attach one more file, but the system would not let me add more than 3 files in a reply.

So, here is the screenshot of the Form with TrueView embedded.

Hi Balaji,

I'm trying to do the above (for Acad & TrueView 2012 and a bit more elaborate though).

I followed your instructions for registering the TrueView assemblies.

I get this error when calling AxACCTRLLib.AxAcCtrl.PutSourcePath(path);

"Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))"

Any idea what causes this? 

Thanks,

alex

In my experience, that error is caused because TrueView was not the last Autodesk product installed.  AutoCAD, for instance, registers a different DLL with the same name.

Try running the TrueView installer again, and see if you have the same problem.

[Balaji_Ram]

Yes, you are right. 

TrueView 2014 has to be installed as the last product.

But this has been fixed in TrueView 2015. The ActiveX control is now renamed as "dwgviewrAcCtrl.dll" and can be found in "C:\Program Files\Common Files\Autodesk Shared"

That's really good to hear.  From an IT and Development perspective - that requirement was kind of a pain.

Hi Balaji,

What about True View 2015?, as I can't find AcCtrl.dll in its installation directory.

Hi Gaston,

You will find it as "dwgviewrAcCtrl.dll" under "C:\Program Files\Common Files\Autodesk Shared" to avoid naming conflict with AutoCAD's AcCtrl.dll

Hi Balaji,

Thank you very much, I'll give it a try.

Thank you for the tip. I wouldn't have thought of that in a milion years.

About your post mentioned below:

The crosshairs indeed disappear after restoring a minimized window, but a left-click restores it. But I am using TV 2012.

I entierly agree with the speed issue, it is a big pain. OTH, I couldn't find anything better than TV, so...

(I played a while with Teigha, but couldn't make it work offhand and didn't have the time to go deeper)

One other thing: can I use the TV2015 control on a system with A2012 only?

1. If i give rebuild the solution, axAcCtrl  controls are missing and Acc**.dll is deleting automatically. then through error while debug.

2. When selecting the file from listbox, displaying time is very slow....

3. Is any code to turn off the  Paper space, orbit and mini tool set in viewer.

Is it possible to display TrueView inside HTML page, please? With other words, I need to display DWG files in HTML.

Thank you

Never tried it, but it's probably possible. See this link: https://social.msdn.microsoft.com/Forums/en-US/a162cc32-f559-4a2a-9221-67782bcdc129/calling-activex-... Cheers
