API callback function

[Bob724]

I have this API callback function, but it's only documented in C++ code. :(

virtual void File_Switch(CVideoDecoderSettings* pSettings)

pSettings represents a handle.

I was just curious how to set this up in VB so it will return the value it's supposed to(or however that works) :D

Anyone got any suggestions?

Thanks,

Bob

I guess the function should be in VB something like:
Public Sub File_Switch(ByRef pSettings As Long)
Not 100% sure about the Byref...
You'll have to copy the pointer to a CVideoDecoderSettings variable, so you can access the properties of this (I assume) class.

OK, but how do I actually get a value to be returned from this, and how and where do I actually use the function? Don't I have to use the AddressOf operator,too somewhere? :confused:

Please help

Thanks,

Bob

I don't know in this specific case, but you'll probably need to call an Init function, probably yuo have to use Addressof there to pass a pointer to the function.
The function itself must be places in a module.

Oh well--
Thanks anyways.

I'll can use another function call, and maybe I'll try using the function in a class module to run asynchronously to the program as an activeX DLL or activeX EXE that generates an event in the main program. I think that's about it, though.

Thanks
