+    IOleCommandTarget* target;
+    HRESULT hres;
+    TRACE("(%p)->(%d %d %s %p)\n", This, cmdID, cmdexecopt, debugstr_variant(pvaIn), pvaOut);
+    hres = IUnknown_QueryInterface(This->doc_host.document,&IID_IOleCommandTarget, (LPVOID*)&target);

document may be NULL here.

+    if(FAILED(hres))
+        return hres;
+    hres = IOleCommandTarget_Exec(target, NULL, cmdID, cmdexecopt, pvaIn, pvaOut);
+    IOleCommandTarget_Release(target);

Please write a test case for this. MSDN seems wrong in this case. It indicates in one place that we should use CGID_MSHTML as group GUID, and NULL in the other. The test should make it clean, which version is true.
