the code follow-

while( (bret = getmessage( &msg, null, 0, 0 )) != 0) {      if (bret == -1)     {         // handle error , possibly exit     }     else     {         translatemessage(&msg);          dispatchmessage(&msg);  //onee message box here     } }

finally found when return true; in loop control come out of loop(but not in approach) but getmessage not useful me infact when reomved program working fine. in presence having infinite loop. because created dialog using createdialogparam() , dialogproc called through createdialogparam() , used wm_commnands handle message received according application , feel no use of getmessage (please point if wrong)
