[Q]: Dynamic Loading of DLL

Hi all,

I am working on audio driver [unified audio model].

I have a middle layer between my application and my driver and it is hidden.
My application uses standard API provided by the middle layer, like
waveOutOpen.

The middle layer I am refering to, is the waveapi.dll & audevman.dll.
now this middle layer is making WAV_Init, WAV_IOControl ... calls by
decoding its standard APIs, like waveOutOpen.

now, the point is, my application wavplay.exe is not specifically using any
of the entry points of my audio driver directly.

when I load my audio driver at boot time, everything happens normally.
and when i try loading my audio driver at runtime, it is not
loaded, and my application fails.

so, now I would like to know whether I need to change any thing in my
registry
or something else so that my audio driver gets loaded at runtime.
I have changed my registry from:

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\audio]
"Prefix"="WAV"
"Dll"="audio.dll"
"Order"=dword:0

to:

[HKEY_LOCAL_MACHINE\Drivers\audio]
"Prefix"="WAV"
"Dll"="audio.dll"
"Order"=dword:0

regards

You will need to manually load it, there is nothing that will do it for you
once you disable the boot time loading.

ActivateDeviceEx() is what you need.
