DirectSoundEnumerate

My app uses waveout and if available directsound. If I link to dsound.lib and my app is run on a machine that does not have directx installed, user will receive 'dsound.dll not found message'. Therefore I would like to use COM interface so that I don't have to link to dsound.lib.

I only use two dsound.lib functions: DirectSoundCreate and DirectSoundEnumerate. I can use COM interface to do DirectSoundCreate but I don't know how to do DirectSoundEnumerate. Thanks for your help!

What do you mean? DirectSoundCreate and DirectSoundEnumerate are just normal functions, not COM interfaces. Why can't you do DirectSoundEnumerate while you can do DirectSoundCreate?

I can accomplish a DirectSoundCreate by doing a CoCreateInstance on the CLSID_DirectSound / IID_IDirectSound but there's no COM interface or method to accomplish a DirectSoundCreate. Therefore I need to extern it and link to dsound.lib which causes 'dsound.dll not found' message to appear when user does not have DX installed. However, I think I'll just dynamically link.

Oops, in previous text substitute 'method to accomplish a DirectSoundEnumerate' with text 'method to accomplish a DirectSoundCreate'.

That's easy to accomplish. Use LoadLibrary to load the dsound.dll. If sucessful, use GetProcAddress to get the function pointer. Note the actual function names are DirectSoundEnumerateA (ANSI version) and DirectSoundEnumerateW (Unicode version).
