How is the function you're calling declared? [modified] I mean the function in the server. What kind of argument are you supposed to pass, a VARIANT that contains a SafeArray? [/modified]

Ok, try the following:
- Create a SafeArray with a call to
::SafeArrayCreate()and set theVARTYPEparameter toVT_UI1. - Get the data buffer of the SafeArray with a call to
::SafeArrayAccessData()and copy whatever data you'd like into the buffer. - Release the bufer when you're done with it with a call to
::SafeArrayUnaccessData(). - Call the
fun()function.
Look the SafeArray functions up for information on how to call and use them. Begin at SafeArrayCreate[^].
