Unable to lock\unlock surface

I bet you're right, you do declare variables twice, which is probably your entire problem.

Remove these lines:

//Pointer 2 ddraw obj
LPDIRECTDRAW lpdd;

//used to hold the DirectDraw surface description
DDSURFACEDESC ddsd;

//Where the interface pointer will be placed when the surface is created
LPDIRECTDRAWSURFACE lpddsprimary;

from your initialization -- these are already declared as globals.

Okay that solved the problem man did i make a stupid mistake well atleast i learned some debuging skills. Thanks for all your help.
