What is the VB.NET syntax??? Plz Help

[KK_Zanok]

I have a Fuction call written in C++ as follows

dwReturn = mciSendCommand(0, MCI_OPEN,
MCI_OPEN_ELEMENT / MCI_OPEN_TYPE,
(DWORD)(LPVOID) &mciOpenParms)

I am converting this to VB.NET and the problem occurs in passing the last argument (DWORD)(LPVOID) &mciOpenParms whose return type is Long. I can't understand the C++ meaning of the parameter. Do any of you have an idea of it's c++ format or know how to specify it in the VB.NET code. Help Please.
