Introduction

This is a known but a different puzzle game. The images of puzzles are not included; in fact, the images are captured from your desktop! First of all, you can select the game difficulty: easy, medium, hard, and by pressing the Start button, the game will begin after the number of seconds you have specified (default is 2 seconds).

Game instructions

• to move a rectangle, select the first and then a second one by clicking on the rectangles.
• to rotate a rectangle by 180 degrees, right click on the rectangle.
• to reveal the borders of each slice, you can click the middle button of the mouse.

Here are the main methods:

// - Saves the bitmap of display DC to a memory DC
void        CaptureDesktop();

// - Replaces two rects in memory device context
void        ReplaceRects(CRect rectSource, CRect rectDest);

// - Inverts selected rect
void        InvertRect(CRect rect);

// - Draws a frame around a rectangle
void        FrameRect(CRect rect, BOOL bClear=FALSE);

// - Draws a frame around all rectangles
void        DrawFrames();

// - Checks if user has been corrected all rectangles
int        CheckForWin();

// - Returns rect of selected square
CRect        GetSquareFromPoint(CPoint point);

// - Draw all frames for help or clear them all
afx_msg void OnMButtonDown(UINT nFlags, CPoint point);

// - Invert selected rectangle
afx_msg void OnRButtonDown(UINT nFlags, CPoint point);

This is not a new game, just an attempt to help others on how to write such programs and may be find some techniques from this. Any suggestions and refinements are welcome. Enjoy the game!
