Something like:

BYTE* buffer = new BYTE[bmpwidth*bmpheight*bmpdepth];
...
pTest->Lock( blah );
copy_all_pixels_from_the_locked_surface_to_"buffer"();
pTest->Unlock();
...
send( blah, (unsigned char*)buffer, blah

however:

1) since it looks like you have a BMP loading function (GetBmp), you probably already have the pixels in their raw form before they get put into the DirectDraw surface.

2) the machine at the other end of the connection might not support the same pixel format for the surfaces (e.g. client graphics card may only support 565 and server may only support 555 so the locked data would be incompatible), so once again sending the raw BMP over the connection would make more sense.
