Re: System Tray Icon HELP Phil J Pearson23-Apr-02 23:32 Phil J Pearson 23-Apr-02 23:32  When explorer restarts it broadcasts a registered message "TaskbarCreated". You can process this message to redisplay your icon. Regards Phil Re: System Tray Icon HELP 23-Apr-02 23:39 23-Apr-02 23:39  Hi, Phil Can u please elaborate on that.. what kind of message is sent etc.. Sameer Re: System Tray Icon HELP Phil J Pearson24-Apr-02 0:43 Phil J Pearson 24-Apr-02 0:43  The message is only sent if the system in question has IE4 or later. As I said, it's a registered message. You get its message number like this... const UINT wm_TaskbarCreated = RegisterWindowMessage(_T("TaskbarCreated")); Then, in the WindowProc of the top-level frame window of your app. do something like this... if (nMsg == wm_TaskbarCreated) m_pTrayIcon->ReloadTheIcon(); A better way would be for your tray icon class to hook the WindowProc and be responsible for reloading itself. That avoids having to inject a chunk of code into an entirely unrelated class. Unfortunately I don't have time to explain all about that... Hope this helps, Phil Re: System Tray Icon HELP - Answer Sameer Maggon24-Apr-02 1:53 Sameer Maggon 24-Apr-02 1:53  Here is the article for people who have the same problem in future Regards Sameer address to hostname 23-Apr-02 19:54 23-Apr-02 19:54  Hi All, How to resolve ip address to hostname in WIN32? for example, given ip address 204.127.222.1, find the hostname (say, MYDOG ). Thanks. Re: address to hostname Joaquín M López Muñoz23-Apr-02 20:15 Joaquín M López Muñoz 23-Apr-02 20:15  Use Winsock function gethostbyaddr. If you're not used to this library, remember you have to initialzie it before attempting to use it (have a look at WSAStartup.)

Place a breakpoint on the line where you want the execution to stop break (right-click->Add breakpoint), press F5, and when the breakpoint is reached use F5 (resume), F10 (step over), F11 (step into) and so on. All command can be found in the debug window. /moliate Does the tool like yacc exists in windows platform? Feng Qin23-Apr-02 18:37 Feng Qin 23-Apr-02 18:37  As title. I'm amumu, and you? Re: Does the tool like yacc exists in windows platform? Sameer Maggon23-Apr-02 20:21 Sameer Maggon 23-Apr-02 20:21  Yes.. ofcourse.. you can try Bison for windows.. Sameer Re: Does the tool like yacc exists in windows platform? moliate23-Apr-02 20:23 moliate 23-Apr-02 20:23  I assume it has been ported. Otherwise there is a c-c in java named javacc (of course).

NicholasCougar23-Apr-02 17:06 NicholasCougar 23-Apr-02 17:06  Hi, I am practice RTTI excerices and encounter such a debug result. struct NCL_Runtime CVehicle::structCVehicle= {szCVehicle, sizeof(CVehicle), 0xffff, NULL, NULL}; debug result is J:\pearl\Sim02\Vehicle.cpp(16) : error C2065: 'NULL' : undeclared identifier Plz tell me WHY?????? Best regard. I confess that I am a stubborn guy, but why not put things thoroughly, logically and systematically clean. One concrete prolem is worth a thousand unapplied abstractions. Re: NULL is not recognized!!!! Joaquín M López Muñoz23-Apr-02 20:02 Joaquín M López Muñoz 23-Apr-02 20:02  NULL is not a C++ keyword, but rather a macro defined in a lot of usual headers, like <stdlib.h> or <windows.h>. In your case, none of these headers happens to be included. You can safely replace NULL with 0. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: NULL is not recognized!!!!

Es muy duro escribir un libro ?, Me refiero a si es una tarea a la que te tienes que dedicar 100 %. Como funciona ese mundo ?

Braulio Díez wrote: Es muy duro escribir un libro ?, Me refiero a si es una tarea a la que te tienes que dedicar 100 %. Cono mijo. No puedes imaginar. Es ridiculo a veces. La cosa es que los publisher no quieren intender que muchas veces estamas escribiendo en algo que esta in beta y no funciona bien. Tampoco no tiene instrucciones ni nada. Pero ellos todavia esperan que nosotros comple con las fechas. Muchas veces el resultado es que tenemos que avanzar y terminar algo que sabemos no es nuestro mejor trabajo. En terminos de horas, si toma un monton de tiempo escribir un libro y los publisher actua como el libro es tu unico trabajo cuando normalmente es algo que hacemos en la noche. Te digo, no es un trabajo facil. Pero la cosa es que me gusta ayudar a la gente y en eso recibo me pago.

In my apps, the control I've dragged first on the dialog is first on focus and so on for the others... How can I change this order without having to change the focus manualy through the code? Bluute tette!
