[DUG] Anyone with 5 minutes spare time?

[Ross Levis]

I've already got a file called DirectSound.pas which is similar to those on
the internet but none of them have this particular interface which I believe
was introduced in DirectX 9.

 

Cheers,

Ross.

Just to clarify, directsound.pas (or similar units floating on the net)
should give you interfaces to the Dsound.dll.  this is what you need to do
things like below.

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.
