Syntax


HRESULT execCommandShowHelp(
    BSTR cmdID,
    VARIANT_BOOL *pfRet
);

Parameters

cmdID
[in] BSTR that contains an identifier of a command. It can be any command identifier given in the list of Command Identifiers.
pfRet

Remarks

Do not invoke the IHTMLDocument2::execCommand method until after the page loads.

This method is a wrapper function for the IOleCommandTarget::Exec method to enable scriptable execution of some command constants. IOleCommandTarget::Exec provides better performance and greater versatility than this method. You can obtain an IOleCommandTarget interface by calling QueryInterface on the IHTMLDocument2 interface using IID_IHTMLDocument2 for the IID.
