Hi wine-users! My first time here so a big hello to everyone! I've only started working with wine two days ago and must say I'm amazed: It's smooth beyond my expectations. But I'm experiencing a problem with my current task: I'm using wine 1.0 on Ubuntu Linux 8.04 to run a specialized application/service (recognizing scanned business cards), have also tried 1.1.32. To automate the recognition process I'm trying to code a small commandline tool that's supposed to look at a JPEG file, analyze it and report its findings. That tool is just a wrapper for some application (cardiris) which offers its service through the COM framework. My problem: I have never done any COM stuff before and know almost none of it. I do have some example .NET C# code that works on a native Windows installation, but I failed to get it running under wine with either dotnet20 or Mono. I came about the very lightweight disphelper plain-C-framework (http://disphelper.sourceforge.net/) which gave me some pleasant surprises at first: Calling some simple methods on a COM object just worked fine. Here's some code that works OK: // Create the main object dhCreateObject (L"Cardiris.Application", NULL, &ci_app); // Analyze the image, returns the result as an ICard object in ci_card DISPATCH_OBJ (ci_card); HRESULT hr_Recognize = dhGetValue (L"%o", & ci_card, ci_app, L".Recognize(%s, %d, %b)", img_filename, 3017, TRUE); But now I'm stuck: ci_card is another COM object whose properties are just the thing I ultimately want. But whichever property I try to access, I always get an "Object doesn't support this property or method: 'LastName'" error: // Get the value of "ci_card.LastName" wchar_t * last_name; HRESULT hr_GetValue_LastName = dhGetValue (L"%s", & last_name, ci_card, L".LastName"); It doesn't seem to be my own mistake, though, because the same code does work on a Windows machine. (Under wine it bails with the error mentioned above, under Windows the string last_name gets set to the correct value.) Now, do I stand any chance to make this work? I wouldn't mind some different approach or some workaround, but to me it seems that the dhGetValue call on the ci_card object fails at some deeper level in the COM machinery (although no errors/warnings/fixmes show up in the output of wineconsole). Ah, maybe that's important, too: I need to register two things for the application to work, a DLL using regsvr32 and an executable (registers itself when invoked with some commandline switch). I *think* that the ci_card object's class is defined in the DLL, whereas Cardiris.Application is from the executable. Would anyone be some kind as to share their ideas? I'd really appreciate even pointers as to how to go on debugging this. Thanks in advance and best regards ----Daniel
