A bitmap index consists merely of multiple lines of bits A line of bits is called a bit vector (a vector is any one-dimensional array) Suppose you have a table, Table2, with a column called sex and a bitmap index on sex The sex column can have three possible values: M or F or NULL Table2's data is shown below: Table2sex F M F F Because there are three possible values for the Table2sex column, the bitmap index for the column contains three bit vectors Each entry in a bit vector is one bit long Because Table2 contains four rows, the length of each bit vector is four bits A bit value of one means true A bit value of zero means false (If all vectors have a zero bit, the row in that position is a deleted row) The bit vector is in order by row number, and the position of a bit in its vector matches the position of the ow in the data table Here is the bitmap index result for Table2 M vector 0 (M is false) 1 (M is true) 0 (M is false) 0 (M is false) F vector 1 (F is true) 0 (F is false) 1 (F is true) 1 (F is true) NULL vector 0 (NULL is false) 0 (NULL is false) 0 (NULL is false) 0 (NULL is false).

During this, we should see the shape drag out to its nal size as the mouse moves, as shown in Figure A94 Dragging out a shape on the screen requires us to perform the following sequence of operations 1 When the mouse button is rst pressed (signalled by a MouseDown event red by the Panel control), the X and Y coordinates of its current location are recorded in two pairs of variables: startX, startY will indicate the location of the top, left of the shape to be drawn; mouseX and mouseY will indicate the current mouse location Since both pairs of coordinates are the same, they will record the same pair of values 2 The current state of the graphics inside the panel is recorded as a bitmap This will be our reference bitmap that we will use to continually return the image on the panel to its initial state during the dragging operation to remove the rubber-band drawing of the shape before replacing it with a new one The illusion of moving a shape on the display is accomplished by clearing the shape off the display and re-drawing it in a new location The reference bitmap will allow us to return the display to the way it was before the new shape was drawn 3 As the mouse pointer is dragged across the screen (causing a MouseMove event), we continually update the mouseX and mouseY coordinates This keeps track of the other corner of the rectangle in which a shape will be drawn We also draw the shape we want on the panel in its new position, using its Draw() method and using the reference bitmap to remove it from its previous position 4 When he mouse button is released (causing a MouseUp event), the reference bitmap is copied back to the display for the last time and the shape is drawn on it We can then destroy the reference bitmap, since having nalized the shape.
