Vc6 receives the stop message in the loop body

For example, Enter text in the text box, click the search button to start searching, and click the button again to make m_bsearch = false. The loop body receives messages and stops searching. Some code is as follows:

M_precordset-> movefirst ();
While (! M_precordset-> EOF & sname! = Text & m_bsearch = true)
{
// Receives the stop message
While (peekmessage (& MSG, null, 0, 0, pm_remove ))
{
Translatemessage (& MSG );
Dispatchmessage (& MSG );
}
// Retrieve column's value:
Var_value = (m_precordset-> fields-> getitem
(_ Variant_t (long (COL)-> value );

If (var_value.vt! = Vt_null & var_value.vt! = Vt_empty)
Sname = (char *) (_ bstr_t) var_value;

M_precordset-> movenext ();
}
