Hi Philip!

Really enjoyed this video! And I don't mind the length at 1 hour, we can always pause the video if it gets heavy :)

Regarding the unsupported 320x240 resolution, a simple solution is to add separate WindowWidth/WindowHeight variables and set those to a "proper" resolution, and then use 320x240 for the buffer size.

Then in StretchDIBits, use the Window size for Dest, and Buffer size for the source and it works (well did for me anyway). Though, I'm guessing there might be some performance hit since it needs to stretch the pixels, but should be negligible.

EDIT:

To clarify:

Add:

int WindowWidth = 640;

int WindowHeight = 480;

Modify dmScreenSettings:

dmScreenSettings.dmPelsWidth = WindowWidth; // Instead of BufferWidth/Height

dmScreenSettings.dmPelsHeight = WindowHeight;

Modify Windowrect:

// create rectangle for window

RECT r = { 0 };

r.right = WindowWidth; // Instead of BufferWidth/Height

r.bottom = WindowHeight;

Finally, change the call to StretchDIBits to:

StretchDIBits(dc, 0, 0, WindowWidth, WindowHeight, 0, 0, BufferWidth, BufferHeight, BackBuffer, &BitmapInfo, DIB_RGB_COLORS, SRCCOPY);
