On many context menus you will see an item in boldface. For example, if you right-click a text file, you will most likely see “Open” in boldface at the top of the mean. What does the boldface mean?<\/p>\n
The boldface menu item is the default command for that menu. It represents the action that would have occurred if you had double-clicked the item instead of viewing its context menu. <\/p>\n
In the above example, the fact that “Open” is in boldface means that if you had double-clicked the text file instead of right-clicked it, you would have opened the document. <\/p>\n
Programmatically, the default menu item is set via the SetMenuDefaultItem function<\/a> and can be retrieved with the corresponding GetMenuDefaultItem function<\/a> <\/p>\n If you put a default menu item in a submenu, then Windows will invoke the default item in the submenu when you double-clicking the submenu’s parent. But if you put a default menu item in a top-level menu (i.e., not on a submenu), then it is your responsibility to invoke the default menu item when the user double-clicks the object that led to the menu. (This last bit should be obvious: It is the code for the object being clicked on which decides what to do on a double-click.) <\/p>\n
