salut !

bon, recement, j'ai posté un msg demandant comment faire plusieurs boites de dialog
(cf : plusieurs dialogs [API])

bon, comme dit, ca marche.

mais j'ai pas compris comment les faire comuniquer entres elles ?

vous me dite de fairemes propres message du style
#define WM_VALIDSONG WM_USER+1

puis de les envoyer avec SendMessage.

quelques petits trucs, cloches, enfin, j'ai pas compris :

1- pourquoi, a quoi ca sert, WM_USER+1
2- comment on utilise SendMessage (d'hab, j'utilise SetDlgItem ou GetDlGitem et pas les trucs a ralonge...)

PS : je tiens a preciser : mon prog est composé de 2 dialogs, celle de depart a un texte static avec pour Id : IDC_STATCONF

la deuxieme, elle a un bouton d'Id : "ID_BUTCONF".

quand j'appuie sur le bouton, je veux que le message "PRIS", apparaisse sur le bouton.

vala le code. en fait, c'est pas vraiment l'exemple decrit mais c'est similaire a l'exception que je dois reproduire ce code (que je cherche !) autant de faois qu'il y a de boutons, donc de variables bool....

code :

#include <windows.h>
#include <stdlib.h>
#include <stdio.h>
#include <commctrl.h>
#include "resource.h"

HMENU hMenu;

Voila ce que dis la documentation sur les API, je pense que tu en a une non ? :

The WM_USER constant is used by applications to help define private messages.

WM_USER


Remarks

The WM_USER constant is used to distinguish between message values that are reserved for use by Windows and values that can be used by an application to send messages within a private window class. There are five ranges of message numbers:

Range Meaning
0 through WM_USER - 1 Messages reserved for use by Windows.
WM_USER through 0x7FFF Integer messages for use by private window classes.
0x8000 through 0xBFFF Messages reserved for future use by Windows.
0xC000 through 0xFFFF String messages for use by applications.
Greater than 0xFFFF Reserved by Windows for future use.
Message numbers in the first range (0 through WM_USER - 1) are defined by Windows. Values in this range that are not explicitly defined are reserved for future use by Windows.
Message numbers in the second range (WM_USER through 0x7FFF) can be defined and used by an application to send messages within a private window class. These values cannot be used to define messages that are meaningful throughout an application, because some predefined window classes already define values in this range. For example, predefined control classes such as BUTTON, EDIT, LISTBOX, and COMBOBOX may use these values. Messages in this range should not be sent to other applications unless the applications have been designed to exchange messages and to attach the same meaning to the message numbers.

Message numbers in the third range (0x8000 through 0xBFFF) are reserved for future use by Windows.
Message numbers in the fourth range (0xC000 through 0xFFFF) are defined at run time when an application calls the RegisterWindowMessage function to retrieve a message number for a string. All applications that register the same string can use the associated message number for exchanging messages. The actual message number, however, is not a constant and cannot be assumed to be the same between different Windows sessions.

Message numbers in the fifth range (greater than 0xFFFF) are reserved for future use by Windows.
