Determining the Size of a Help Balloon
If your application does extensive drawing, the Help Manager provides three functions that may be helpful for determining the dimensions of your help balloons before displaying them. Then you can ensure that your help balloons don't obscure an area that requires an inordinate amount of time to update.
To get the size of a help balloon before the Help Manager displays it, use the HMBalloonRect or HMBalloonPict function. To get the size of the currently displayed help balloon, use the HMGetBalloonWindow function.
