iTunes plugin issue

[GoogleCodeExporter]

Please describe the problem:
When LCDMisc attempts to initialize iTunes, CoCreateInstance returns 
0x80080005, and no track info is displayed/lcdmisc hangs.

What version of the product are you using? On what operating system?

Windows 7 x64
latest LCDMiscellany x64

I'd blame this on iTunes or Windows.  When CoCreateInstance fails, not a whole 
lot I can do, as far as I know.

A simple test with the following console application works, successfully 
pausing the current track:

#include "iTunesCOMInterface.h"

int main()
{
    CoInitialize(NULL);

    HRESULT  hRes;
    IiTunes* iITunes;

    // note - CLSID_iTunesApp and IID_IiTunes are defined in iTunesCOMInterface_i.c
    hRes = ::CoCreateInstance(CLSID_iTunesApp, NULL, CLSCTX_LOCAL_SERVER, IID_IiTunes, (PVOID *)&iITunes);

    iITunes->Pause();
    return 0;
}

Hmm...  That's odd.  I assume you've tried recompiling my iTunes dll.  I'd 
expect a versioning issue to return a different error, but you never know.  I'm 
not sure what to suggest.

It's been a while since I added iTunes support, and I don't use iTunes myself.  
Haven't been messing with LCD Miscellany at all lately, either.  As a result, 
it's rather unlikely that I'll ever get around to looking into this.

Yes, I've recompiled the iTunes DLL with the latest COM interface for iTunes.
I'd really like to get this working, as I've used it a lot back when I was on 
x86.
Right now I'm reading up on COM... any help would be greatly appreciated!

I really don't know COM well, unfortunately.  The call to CoInitialize() in the 
dll is succeeding, right?

Suppose could be a result of stack corruption, but sounds too consistent for 
that.

Have you tried the 32-bit version of LCD Miscellany?

Yes, I've tried both variants to no avail.

CoInitialize is always returning S_FALSE, which means that the COM instance is 
already initialized.  Even calling CoUninitialize before init yields the same 
issue...

I have tracked down the issue...
In the release build of LCDMisc, the Character Set is undefined, when it should 
be Multi-Byte Character Set.

Weird I know, but this seems to fix the error for me!

Funky...Where's the option for that?  And how the heck did you figure that out? 
 :)

I don't even know, I just tried a whole bunch of different compile options.
It's under Project Settings -> Configuration Properties -> General -> Character 
Set

"Use Multi-Byte Character Set"
