CALL_EXTERNAL in idl virtual machine [message #44198]

Hi everybody!

I tried to use CALL_EXTERNAL in an application that should run without a
license in IDL-virtual machine. When running the program I get an error
that "EXECUTE" is disabled in IDL-VM. The point is that there is *no
place* where I call execute. Only CALL_EXTERNAL is used to call functions
in a (WINDOWS-)DLL. The documentation didn't say anything (at least to me)
about a license limitation for CALL_EXTERNAL.

Any idea how to solve this problem? By the way: I can't change the DLL
since I dont have the sources.

Thanks for any advice,

Georg

I don't get it, the avi dlm is what it is: a DLM. I am not sure why you need
call external? On IDL start, IDL will scan for DLMs. The commands from the
DLM are indistinguishable from native IDL routines and should work just
fine. Can you post your code?

These .dlms should work fine. I have used them extensively in VM
applications. There must be something else causing this.

Hi,
I have used the AVI dlm, dll and have successfully used it with the
virtual machine.
I can post (or email) the sav file if anyone wants to check it out.
It is an embarrasingly simple gui that reads in jpgs or pngs, and creates an
avi.

Cheers,
bob

PS is there an execute function somewhere hidden in one of
your called files? I use the dlm with
"BUILD_DATE MARCH 2002"
and I think I am using the latest (aviIDL56.zip).
Also, what version of the VM do you have?

Yes I am. The library I am calling is the avi interface from here:
http://www.kilvarock.com/freesoftware/dlms/avi.htm
I used version 5.5 and 5.6.

There is another version of this as DLM from RSI
http://www.rsinc.com/codebank/search.asp?FID=139
which I have not tried yet.

Hm, I thought we discussed this before and came to the conclusion that
call_externals are allowed in the VM. Have you isolated the violating call?
Are you sure it is the call external statement?

Hi Rick!

You where right. The object oriented part of IDL uses the "Execute"
feature to resolve and compile new classes
The point is, that I wrote a class that is calling the DLM.

You need to compile (only custom?) classes explicitly to include them in
the save-files. I think is is a field where RSI should provide a
"RESOLVE_REALLY_EVERYTHING" procedure instead of "RESOLVE_ALL" which isn't
very helpfull. Althoug the error message of the VM did not help to find
the cause of problem.

Regards,

Georg
