Description
Repositions and resizes the toolbar by a specified ratio.
Use ChangeScale to change the scale of the toolbar.
ChangeScale modifies the position and size of a toolbar as well as rescaling the buttons. Thus, ChangeScale modifies the Top, Left, Width, and Height properties.
The M and D parameters define a fraction by which to scale the control. The M parameter is the multiplier and the D parameter is the divisor. For example, to make a control 75% of its original size, specify the value of M as 75, and the value of D as 100 (75/100). Alternately, the same results are achieved by specifying the value of M as 3, and the value of D as 4 (3/4). Both fractions are equal and result in the control being scaled by the same amount, 75%.
