Custom mouse icon used if MousePointer is 99.

Description

The MouseIcon property provides a custom icon that is used when the MousePointer property is set to esriPointerArrowHourglass (99).

Remarks

In most development evironments the control's property pages can be used to load either a cursor (.cur) or icon (.ico) file. A cursor contains a custom 'hotspot' location and can be any size. The 'hotspot' location for an icon file defaults to the center of the icon. This property cannot be used to load animated cursor (.ani) files.

To programatically create an object implementing IPictureDisp there is the win32 function OleLoadPicture or helper methods depending on the development environment.

Description

Returns or sets keys on the keyboard that will be intercepted by the TOCControl, triggering the OnKeyDown and OnKeyUp events when pressed. These keys are often hidden from the TOCControl by the development environment container. By default the KeyIntercept is set to esriKeyInterceptNone.

Many development environment containers use the up, down, left and right arrow keys to change control focus on a form. These keys can also be useful for navigating around the display. To intercept the arrow keys and the Tab key combine the enum values using a logical OR operation (esriKeyInterceptArrowKeys OR esriKeyInterceptTabKey, which is 1 OR 4 = 5).
