divide form into equal parts and select label

Question

favorite

I have a windows form with 6 labels (more could be added) and a TextBox. what i want to do : 1) Divide the form into 4 equal quadrants (Quadrants 1,2,3,4). (drawing two colored lined) 2) Color each quadrant for 3 seconds and turn it back to transparent in a sequence. It implies that Form quadrant 1 is red for 3 second then transparent. quadrant 2 is then red for 3 seconds and then transparent and so on infinately.   3) Once a mouse click event is encountered (could be anywhere on the form). Find the quadrant which was colored red at that time.   4) Check in this quadrant if (number of labels == 1) if yes-> show the label.text in the textbox. if not-> then start from step 1 by taking input as the coordinates and size of the currently colored quadrant. I am a new at this. Can anyone please tell me how i do this.
