Start with the project you created in Setting Container Offsets:
Add the following code to the WndProc
function, after the L_ContainerCreate( pContainer, hWnd ) ; function call in the WM_CREATE
message:
{ // SET THE SCALING FACTOR
VECTORPOINT vptScalarNum, vptScalarDen;
vptScalarNum.x = nZoomFactor;
vptScalarDen.x = 100;
vptScalarNum.y = nZoomFactor;
vptScalarDen.y = 100;
vptScalarNum.z = 1;
vptScalarDen.z = 1;
L_ContainerSetScalar(pContainer, &vptScalarNum, &vptScalarDen);
} // SET THE SCALING FACTOR
Compile and run the project by selecting Build->Rebuild Solution from the menu, and then Debug->Start Without Debugging.
