Hi everyone.
I've never used interfaces in Windows before and I've got no idea how to do this, so I'm wondering if someone would like to whip up a Delphi function for me. I don't think it would take more than 5 or 10 minutes. I searched the internet extensively and C++ code exists but nothing for Delphi. http://msdn.microsoft.com/en-us/library/ee418863(v=VS.85).aspx I need to access the DSPROPERTY_DIRECTSOUNDDEVICE_DESCRIPTION properties on the above page and specifically return the WaveDeviceID from a given GUID. I have the GUID and need the WaveDeviceID. ie. Function DSGUIDToWaveDeviceID(GUID: TGUID; DataFlow: ??): Cardinal; Very much appreciated J Ross.
