All of the following sequences return E_POINTER:

DWORD buflen = 0;
AssocQueryString(ASSOCF_INIT_DEFAULTTOSTAR, ASSOCSTR_COMMAND,
extensionToUse, _T("edit"), NULL, &buflen);

DWORD buflen = 2000;
AssocQueryString(ASSOCF_INIT_DEFAULTTOSTAR, ASSOCSTR_COMMAND,
extensionToUse, _T("edit"), NULL, &buflen);

DWORD buflen = 2000;
auto_buffer<TCHAR> cmdbuf (buflen + 1);
AssocQueryString(ASSOCF_INIT_DEFAULTTOSTAR, ASSOCSTR_COMMAND,
extensionToUse, _T("edit"), cmdbuf, &buflen);

In particular, cmdbuf remains undefined which causes application
to be undefined and usually not empty.

Some people with the same problem:
