Audioengineendpoint.idl will be in the final SDK for Windows 7. However, I believe there should hardly ever be a need to use the AE_CURRENT_POSITION structure, though, since it is related to Terminal Server. Do you mind saying why you need this? There are some minor audio header corrections between Beta and final release. So if you are trying to get this definition just to make your code build but are not actually using this structure, then hopefully your problem will go away when you move to the final SDK.

I did find the audioengineendpoint.h file which has the definition, But I was looking for the .idl file. I have both SDK and DDK installed for windows 7, but strangly i don't find the file. could you please help me in locating the file. The SDK installed is "Microsoft Windows SDK for Windows 7 (7000.0.4011) The DDK installed is "Microsoft Windows Driver Kit 7.0.7000.1" -Prakash On Tue, Jun 23, 2009 at 10:48 PM, Matthew van Eerde<Matthew.van.Eerde@xxxxxxxxxxxxx> wrote: > audioengineendpoint.idl > > //----------------------------------------------------------------------------- > // Description: > // > // Structure used to report the current frame position from the device to the > clients. > // > typedef struct AE_CURRENT_POSITION > { > // Device position in frames. > UINT64 u64DevicePosition; > > // Stream position in frames used for capture to determine starting point. > UINT64 u64StreamPosition; > > // Current amount of padding (in frames) between the current position and > the stream fill point. > UINT64 u64PaddingFrames; > > // Translated QPC Timer value taken at the time the frame position was > checked. > MFTIME hnsQPCPosition; > > // Calculated value of the data rate at the point when position was set. > FLOAT32 f32FramesPerSecond; > > // Indicates the validity of the position information. > AE_POSITION_FLAGS Flag; > } AE_CURRENT_POSITION, *PAE_CURRENT_POSITION; > > -----Original Message----- > From: wdmaudiodev-bounce@xxxxxxxxxxxxx > [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Pakku > Sent: Tuesday, June 23, 2009 10:04 AM > To: wdmaudiodev@xxxxxxxxxxxxx > Subject: [wdmaudiodev] IDL file for AE_CURRENT_POSITION structure > > Hi folks, > > which is the .idl file that defines the structures like > AE_CURRENT_POSITION > > Looks like this structure is not part of audioenginebaseapo.idl > > -Prakash > ****************** > > WDMAUDIODEV addresses: > Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx > Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe > Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe > Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx > > URL to WDMAUDIODEV page: > http://www.wdmaudiodev.com/ > > > ****************** > > WDMAUDIODEV addresses: > Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx > Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe > Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe > Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx > > URL to WDMAUDIODEV page: > http://www.wdmaudiodev.com/ > > ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/ ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/
