waveout dll help

[Kreuters]

hey

i am trying to query the windows API to discover the capabilities of a soundcard. i understand this has to be done using the Call Library Function, but i cannot seem to get it to work.

the function i am after is waveOutDevCaps

i have attached my effort so far, but cannot get it to return any information, i presume this is to do with my attempt at providing a Struct pointer using a cluster. is this the way to go about it?

thanks

You must set the cbwoc to the size in bytes of your structure!

also you cant use a LV string in the cluster

I attach an old vi for waveInGetDevCaps that works

thanks, that is exactly what i was after
