biHelp If BorderStyle is bsDialog or biMinimize and biMaximize are excluded, a question appears in the form's title bar and when clicked, the cursor changes to crHelp; otherwise,no question appears.
设置了biHelp为true后,如果将form的BorderStyle设为bsDialog,或者BorderIcons的
biMinimize and biMaximize都设为false,那么在form的标题栏就会有个问号图标,点击后form的光标变为crHelp.
