Dwg Thumbnail and 64-bit System

Anonymous — Wed, 02 Dec 2009 14:59:54 GMT

Hello,

i'm facing an issue while trying to use my application on a 64-bit OS.
Everything works, except the Autocad component for drawing thumbnails, the DwgThumbnail.ocx activex.

it returns me this error: Class not registered (Exception de HRESULT : 0x80040154 (REGDB_E_CLASSNOTREG)).

i tryed to register the activex on my XP 64-bits using both \windows\system32\regsvr32 and \windows\syswow64\regsvr32, and the command tells me it was successful.

But each time i start my software, i got these issues.

Does anyone already succeed to use this component on a 64-bit OS?

Thanks.
Nicolas

Nicolas,

we deliver our app with dwgthumbnail.ocx, Version 1.9.0.0. Some clients
install on 64-bit machines (also on our testing machines, we run vista64 or
win7-64). I haven't heard of any problems up to now.

Bye

Thanks for your reply Herbert.

Could you tell me quickly how you set the registration of this activex when installing your software?
or how you reference it in your project?

Nicolas,
sorry it took so long to answer, I didn't check this newsgroup for a couple
of days.
On the client-machines, we use the regserver-flag in Innosetup for
installation. AFAIK, this does nothing else than a "regsvr32 "
internally.
Registering it manually with regsvr32 works on all our computers here.

We use the control from an application created with Visual Objects. We
place it on a dialogbox an assign the filename of the dwg-file for showing
the thumbnail.

I'm back after several weeks without having a look at this issue.

First, i want to thanks Herbert, who helped me. Thanks to you, i was sure it should work.
I make a lots of several tests, and my conclusion is, that the DwgThumbnail.ocx can run on a 64-bit system, but only if ran in 32-bit compatibility mode.

What make think this to me is: i tryed to create an example project in Visual Studio: only a dll with a command called Test, which open a Form with the Thumbnail component and a button to choose the file to show. I run Autocad 2009, which version is 64-bit, load my dll, and i got the message posted ubove ("Class not registered").
Then, back to Visual Studio, i'm forcing my dll to run in 32-bit mode, and i got a new message: can not load the dll or one of its dependencies.

Back for the last time to Visual Studio, creating a new project, the same one, but in Windows Form mode. so i create an .exe file, and i got the same message as before: "Class not registered". I changed it to run in 32-bit, and then, it finally works! so i can choose a file, and the thumbnails shows up.

That's why i think i need to find a way to run Autocad 2009 in 32-bit mode, for it to be able to load a 32-bit dll. Or to but Visual Studio 64-bit and build my dll with it.

Sorry for the long post, but i hope the long time i spend on this could help some others.
And maybe Herbert or someone else can confirm that the Autocad version match to their DLL or whatever version.

Nicolas, have a look on ADN. There is a setup with 64bit utilities
available, which also seems to contain the dwg-thumbnail control. I haven't
tested it yet.

Thanks Herbert, but i'm not member of the ADN. Because i'm not a full time CAD developper, my company don't think this is usefull.
We had the current version of ADN autocad utilities as the first version of the tool was developped by a sub contractor, who is an Autodesk developper.

But now, i'm on my own. Maybe i should try to think to another solution of creating thumbnails, or forget the idea of compatibility with 64-bit.

If only i was sure the 64-bit utilities version work for this, it could be a great argument to suscribe to ADN.

Nicolas,

maybe I could test something for you or give you some more information.
Please drop me an email to hdotputzateurogisdotde.

Hey Herbert, what do you mean a 64bit Utility? I'm an ADN member, where do I find the download for this? Is it the SDK? Edited by: Enclos_Corp on Feb 8, 2010 12:53 PM

Make a search for "ADN AutoCAD Utilities" on the adn-website.
