IDM_2D_POSITION

Allows absolutely positioned elements to be moved by dragging.

Command group CGID_MSHTML (defined in mshtmhst.h)
Symbolic constant IDM_2D_POSITION
Header file mshtmcid.h

 

Call IOleCommandTarget::Exec with the following parameters.

  • nCmdExecOpt
    Set to OLECMDEXECOPT_DONTPROMPTUSER.

  • pvaIn
    VARIANT of type VT_BOOL specifying whether this feature is to be on or off.

  • pvaOut
    Set to NULL.

IDM_ABSOLUTE_POSITION

Sets an element's IHTMLCurrentStyle::position property to "absolute."

Command group CGID_MSHTML (defined in mshtmhst.h)
Symbolic constant IDM_ABSOLUTE_POSITION
Header file mshtmcid.h

 

Call IOleCommandTarget::Exec with the following parameters.

  • nCmdExecOpt
    Set to OLECMDEXECOPT_DONTPROMPTUSER.

  • pvaIn
    VARIANT of type VT_BOOL specifying whether the element is to be absolutely positioned.

  • pvaOut
    Set to NULL.

This command only applies to site selectable elements. In addition, IDM_ABSOLUTE_POSITION only affects inline styles. If the page defines absolute positioning for the element in a style block, IDM_ABSOLUTE_POSITION will not be able to affect the element's positioning property.

IDM_BACKCOLOR

Sets or retrieves the background color of the current selection.

Command group CGID_MSHTML (defined in mshtmhst.h)
Symbolic constant IDM_BACKCOLOR
Header file mshtmcid.h

 

Call IOleCommandTarget::Exec with the following parameters.

  • nCmdExecOpt
    Set to OLECMDEXECOPT_DONTPROMPTUSER.

  • pvaIn
    VARIANT of type VT_BSTR that specifies a color name or a six-digit hexadecimal RGB value, with or without a leading hash mark, as defined in the Color Table.VARIANT of type VT_BSTR or VT_I4 that specifies the new color. If pvaIn is a VT_BSTR, the value can be a color name or a string representing a six-digit hexadecimal RGB color value, with or without a leading hash mark, as defined in the Color Table. If pvaIn is a VT_I4, the value will be in interpreted as a COLORREF. pvaIn may be set to NULL.

  • pvaOut
    VARIANT of type VT_I4 that receives a COLORREF value. If the current selection uses more than one back color, pvaOut will return a VARIANT of type VT_NULL. Set pvaIn to NULL to retrieve information to pvaOut.

The HTML generated by this command may vary depending on the version of Windows Internet Explorer.

IDM_BACKGROUNDIMAGECACHE

Caches background image(s).

Command group CGID_MSHTML (defined in mshtmhst.h)
Symbolic constant IDM_BACKGROUNDIMAGECACHE
Header file mshtmcid.h

 

Call IOleCommandTarget::Exec with the following parameters.

  • nCmdExecOpt
    Set to OLECMDEXECOPT_DONTPROMPTUSER.

  • pvaIn
    VARIANT of type VT_BOOL specifying whether this feature is to be on or off.

  • pvaOut
    Set to TRUE.

document.execCommand("BackgroundImageCache", false, true);

IDM_BEGINUNDOUNIT

Starts an undo unit. Any DOM changes between IDM_BEGINUNDOUNIT and IDM_ENDUNDOUNIT (including any changes from script) are collected into an undo unit and undone and redone as if they were a single command.

If an undo unit is started through IDM_BEGINUNDOUNIT and any of the following conditions is met, the current undo unit will be ended automatically:

  • When the user does something that would be an undo-able action, such as typing some text.
  • When the current script completes execution and returns to the event loop.
  • When an undo or redo occurs, either when initiated by the user or by IDM_UNDO/IDM_REDO.
  • When undo data is cleared by IDM_CLEARUNDO.

Undo units cannot be nested. If IDM_BEGINUNDOUNIT and IDM_ENDUNDOUNIT called within a another pair of commands, only a single unit will be created to span all editing from the first IDM_BEGINUNDOUNIT to the last IDM_ENDUNDOUNIT.
