Hi all

I try to call a external dll (placed in the bin-directory where the AOS is located). The reference in AX is done.

My call looks like the followingprotected boolean createContractList()
{
    InteropPermission   interopPerm;
    Integer             ret;
    ;

    // get CLR interop permission
    interopPerm = new InteropPermission(InteropKind::ClrInterop);
    interopPerm.assert();

    ret = ch.Sirius.FtxWrapper.SwoxWrapper::FTX_CreateContractList(@"\\GFCFS02\BankFiles\CHTA\FTX");

    CodeAccessPermission::revertAssert();

    if (ret != 0)
        return checkFailed("@GFC2440");

    return true;
}:

The class is running on server

Who can help me out?

in case you add it to the global assembly cache, does that help

Not sure what you mean. I changed the class in Ax from RunOn "Called from" to "server" and recompiled the class.

The dll has version 0.0.0.1

I don't know. It's written from someone else, already left the company. I'll try to find out and give feedback

One more information (maybe it is related to this)

the "SwoxWrapper" is built to call functions in a pascal written dll from external company. Both dlls are placed in Bin-directory on AOS-site. SwoxWrapper is registered in GAC, the original swox dll is not because not possible.

Server is W2k8 R2 (64bit)

Hi again me...

What I believe is that it really is a problem with 32/64 bit

AOS is running on 64bit, the wrapper is built with "AnyCPU" option and the original dll called from the wrapper is 32bit (very old one)

Is this a possible problem and how can it be resolved?

I answered this in another thread. I highly recommend you build a web service to host your 32-bit DLL and call this web service from the AOS server tier.
