The oleacc.dll dynamic-link library recognizes and provides the following standard object identifiers (defined in winable.h). The system reserves zero and all negative values for standard objects.
Clients will receive and use these values to identify parts of a window. Servers use these values to identify the corresponding parts of a window, but must provide positive values to identify any other objects they employ within an application.
| OBJID_ALERT | |
| Refers to an alert associated with a window or application. | |
| OBJID_CARET | |
| Refers to the text insertion bar (caret) in the window. | |
| OBJID_CLIENT | |
| Refers to the window's client area. In most cases, the operating system controls the frame elements and the client object contains all elements that the application controls. List boxes use OBJID_CLIENT for item notifications. | |
| OBJID_CURSOR | |
| Refers to the mouse pointer. There is only one mouse pointer in the system and it is not a child of any window. | |
| OBJID_HSCROLL | |
| Refers to the window's horizontal scroll bar. | |
| OBJID_MENU | |
| Refers to the window's menu bar. | |
| OBJID_SIZEGRIP | |
| Refers to the window's size grip, an optional frame component located at the lower right corner of the window frame. | |
| OBJID_SOUND | |
| Refers to a sound object. Sound objects do not have screen locations or children, but do have name and state attributes. They are children of the application playing the sound. | |
| OBJID_SYSMENU | |
| Refers to the window's system menu. | |
| OBJID_TITLEBAR | |
| Refers to the window's title bar. | |
| OBJID_VSCROLL | |
| Refers to the window's vertical scroll bar. | |
| OBJID_WINDOW | |
| Refers to the window itself rather than a child object. | |
