You're not really showing any newbie-ness here, most CF programmers never have to worry about this kind of stuff. My guess is that this could work if you could compile Snap.cpp with a 64-bit compiler. However, that basically moves your problem from Java to C++. I don't know enough about C++ on Windows to definitively answer that question. http://www.dnjonline.com/article.aspx?id=jun07_access3264 I don't think that you can invoke a 32-bit native program from a 64-bit JVM JNI call. Honestly, my final recommendation would be to look for an alternative to this library that's written in Java.

if it is critical for you to use this COM object, then here is one suggestion. Install CF 32 bit on the server as well, and just have one folder on your server set to use the 32bit connectors just so you can use your COM object.

Re: Creating COM object - troubleshooting

There's nothing (that I know of) stopping them from doing that right now, but you're correct that COM is basically a dead-end - so it makes financial sense for JIntegra not to pursue this.

Yes, you're absolutely correct that 64-bit CF can't instantiate COM objects. But at the point you're using RUNDLL32.EXE to run a DLL function, it's no longer going through COM. And it wouldn't matter if it were at that point, as long as RUNDLL32.EXE can invoke the function in question. Essentially, CF wouldn't be using the DLL at all - it would be opening a shell to a program that could successfully run it. But this is pretty close to irrelevant - there's no guarantee that a COM object exposes useful functions for RUNDLL32.EXE to invoke.

If I missed someone answering this, forgive me, but in CF8 and 9 64-bit, COM Objects will not work...no work around. It has to do with how MS is depreciating com objects and is out of CF's control.

RE: Creating COM object - troubleshooting
Is there some way you could call CFEXECUTE and call a BAT file or something
like that to run the DLL? Would this be a workaround for calling a COM
object from CF9 or a 32 bit object from CF 64 bit? Or is it not possible or
advisable to do this either?

This is a 32-bit .NET assembly. You can tell because it's installed in "Program Files (x86)" rather than just "Program Files". You can only use this from a 32-bit version of CF. Fortunately, you can easily install 32-bit CF on a 64-bit Windows machine, but you'll have to configure the IIS application pool to also be 32-bit. Unfortunately, you lose all the 64-bit advantages when you do this, of course.

RE: Creating COM object - troubleshooting
Stefan, I suspect PHP is 32bit yes... but someone else will have to chime in definitely. It's also possible that PHP uses a marshaling layer like the .NET integration service (which runs on a TCP listening port) that makes it a non-issue. But CF's implementation of COM has always been JNI - which is a native Java thingy. FYI - you should move away from COM if at all possible. It has been deprecated for a long long time by now. -Mark -Original Message- From: Stefan Richter [mailto:ste...@flashcomguru.com] Sent: Monday, April 18, 2011 11:19 AM To: cf-talk Subject: Re: Creating COM object - troubleshooting Thank you.

RE: Creating COM object - troubleshooting
Stefan,
If you are running 64bit you will need a 64bit version of the COM. I know of
no way around that. I would contact the vendor. If it's .NET you can use it
through the .NET integration services (either 32 or 64) but there are a good
number of nuances to that as well.

Hi all,
I'm trying to use a third party DLL called ACA Webthumb

I've installed this on a Windows 2008 server running CF 9.0.1
I'm having issue instantiating the library in CF. I'm using the supplied

WebThumbMaker = CreateObject("Com", "ACAWebThumb.ThumbMaker", "local");
This results in error:
An exception occurred when instantiating a COM object.
The cause of this exception was that: java.lang.RuntimeException: Can not

I also tried using a tag based syntax specifying the DLL directly:
Error:

The assembly that contains the class must be provided to the assembly
attribute.
Does anyone have any tips?

Creating COM object - troubleshooting
Hi all,
I'm trying to use a third party DLL called ACA Webthumb
http://www.acasystems.com/en/web-thumb-activex/
I've installed this on a Windows 2008 server running CF 9.0.1
I'm having issue instantiating the library in CF. I'm using the supplied sample
file that came with ACA. Here's the problematic line from it:
WebThumbMaker = CreateObject("Com", "ACAWebThumb.ThumbMaker", "local");
This results in error:
An exception occurred when instantiating a COM object.
The cause of this exception was that: java.lang.RuntimeException: Can not use
native code: Initialisation failed.
I also tried using a tag based syntax specifying the DLL directly:
Error:
Class ACAWebThumb.ThumbMaker not found in the specified assembly list.
The assembly that contains the class must be provided to the assembly
attribute.
Does anyone have any tips?
Best wishes,
Stefan
