>Sincerelly, I don't understand it. MSDN says that hEnum is passed by val. That means that WNetEnumResource cannot change its value. Then, why passing it by ref? You declare it as passed by val and pass it by ref. Normally, VFP will take the address of your variable and pass it to the API function. How can it work? Does it work like this for you? IMO, it shouldn't work. ... I don't understand... Probably I'm missing something...

The code works; the value of hEnum probably never actually changes, but I haven't checked the value of the handle on return. It works this way, so I'm happy, but I agree, the value shouldn't be getting changed. I'll have to check my C code that I use in my own wrapper.

>>I know - take a look at the declaration in message 185193, where I posted the setup for WNetEnumResource. I meant pass by reference in VFP's terms - the parameter is passed @hEnum in the call to WNetEnumResource, so that the value will come back to VFP; VFP actually copies the value between calls.
