Hello,
We have developed an application that makes use of
MM_MIXM_CONTROL_CHANGE windows event.This is the volume key in the
recent keyboards. The application works fine on windows XP professional.
But does not work on Windows XP embedded .So I feel that I am missing
some XPE component. Could anyone of you help me to find out which
component to be included in XPE to recognize MM_MIXM_CONTROL_CHANGE events.

Thanks & Regards,
Shiju
 
Shiju,

You specifically seem to need these components:
"Primitive: Winmm",
"Microsoft Kernel System Audio Device".


But I'd start with "Audio Control Panel" component and resolve all the
component's dependencies.

Hi,
All the below mentioned components were already included and
dependencies resolved. Still the application does not response to
MM_MIXM_CONTROL_CHANGE events. But we have no issues with Windows XP
professional.Is there any specific components to be included for
MM_MIXM_CONTROL_CHANGE events ?
