Title Body

We have been using an SAP "COM License Bridge" to access their license server and query the hardware key of a system programatically (to reuse with out own licensing). This worked fine on SAP Business one Versions 2007A, 2007B and 8.8, but in 8.81 they seem to have updated their CORBA interface without updating the COM wrapper because we now get memory exceptions when attempting to call the GetHardwareKey function. So I downloaded IIOP.NET and started trying to write my own interface. I never liked that COM wrapper anyway. But I encountered my old nemesis of .NET remoting -- the inability to invoke a remote method without having a common interface defined in both the server and the client. I tried using the IDL to CLS compiler included with IIOP.NET, but I continue to get errors about the interface beign incompatible (SAP did not provide an IDL file). I don't know how IIOP and CORBA determine whether an interface is compatible. But I even tried debugging into IIOP.NET code and forcing it to execute the method despite the incompatibility, but received an empty string back instead of the hardware key I wanted. My next step is to try to implement a fake license server and examine the requests coming in from the production client in the hopes of identifying what they should look like, but I'm not counting on much success considering the difficulty I've had in peering into the innards of .NET remoting already. My real problem is how to get or generate the SAP Business One hardware key, but questions stemming from that include: How do I reflect on or query information about a CORBA interface? I can use the list method of the NamingContext class to retrieve a list of available objects, but I don't see if there is a way to query available methods on an object. Can I dynamically invoke .NET remoting methods without having an interface? I see there's something called DII for dynamically invoking CORBA, but I don't s
