Hi,
i am trying to write a user mode installable multimedia driver (
basically i want to implement the wodMessage ).please visit
http://msdn.microsoft.com/en-us/library/ms713504(VS.85).aspx
i can see my device in the list, however, when someone tries to open the
device, i receive a callback argument with value 0, which is not valid
so no one is able to open the device( AFAIK the device will open only when
the callback is sent, but since it's a value of zero, it's of no use )
can someone help me out here.
i am also trying to search a sample but in vain. Can someone please point me
out to the sample or what am i doing wrong or how should i do it.
waiting for your help
