Another stupid question by a VBer

or maybe it should be Another question by a stupid VBer

No really... What does this code mean particularly the (BYTE)?

bmp.bmBitsPixel = 
            (BYTE) GetDeviceCaps(hdcScreen, BITSPIXEL);

Thanks a mil.

It's a typecast; it converts what GetDeviceCaps returns into a BYTE.

So In Vb could I write the following?

bmp.bmBitsPixel = CByte(GetDeviceCaps(hdcScreen, BITSPIXEL))

[Vlatko]

Yes, but in vb the function returns long.

it is a typecast so it has be in the following format in C++:

(TYPECAST)
//So if you want to return a specific type of value then
//for byte
(BYTE)
//for a handle
(HWND)

//and there are lots of others

Code in C++ uses a lot of casting and special datatypes - which all are really one of a few datatypes, just like in VB.

ANY declaration that is in caps is one of these things
LPCSTR
BYTE x; <- dim x as Byte (signed ie, -127 - +127, with no negative numbers
(BYTE) <- type cast
