Communicates between a rendering engine and the host to indicate that a page refresh has occurred or is being requested. The enumeration values are passed to the IOleCommandTarget::Exec method in the nCmdExecOpt parameter.

Note  This documentation is preliminary and is subject to change.

Windows Internet Explorer 8. Passes an OLECMDID Enumeration command to request that the ActiveX control be installed. This must be the second of two calls to Trident. The first of these calls passes an OLECMDID_ACTIVEXINSTALLSCOPE command to set the Install Scope.

Example:

IOleCommandTarget::Exec(
    NULL,                                // pointer to command group
    OLECMDID_REFRESH,                    // ID of command to execute
    OLECMDIDF_REFRESH_PAGEACTION_ACTIVEXINSTALL, // options
    NULL,                                // pointer to input arguments
    NULL)                                // pointer to command output
