[DUG] Anyone with 5 minutes spare time?

[Cameron Hart]

I have googled it further for you again with the term "directx 9 delphi
pas".  lots of libraries returned that look promising.

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.
