VARIANT_BOOL retVal = object.queryCommandEnabled(cmdID);

Standards information

There are no standards that apply here.

Parameters

cmdID [in]

Type: BSTR

BSTR that specifies a command identifier.

Using queryCommandEnabled ("delete") on a TextRange object returns VARIANT_TRUE, while queryCommandEnabled ("delete") on a document object returns VARIANT_FALSE. However, execCommand ("delete") can still be used to delete the selected text.
