Le pb est simple : le fichier "download.h" inclut windows.h qui inclut
winsock2.h qui n'est pas prot&#233;g&#233; contre la multi-inclusion => erreur
"type redefinition"



=> appelle 1 seule fois Windows.h (en premier), &#231;a devrait marcher

Salut,
C'est plutot winsock2.h qu'il faut inclure avant windows.h

Maintenant &#231;a compile sans erreurs, mais quand je lance le programme il plante directement apr&#232;s...

Qu'est-ce qu'il dit ?

cs_mayti · Answer

machin.exe a rencontr&#233; un probl&#233;me et doit ferm&#233;...

simtiers · Answer

Si c'est XP : clique sur voir le rapport, puis sur voir le contenu



=> le code de l'erreur est marqu&#233; en 1er je crois

=> du type 0xc0...05 ou 0x000001d



A quel niveau &#231;a arrive (la fen&#234;tre a-t-elle le temps d'&#234;tre cr&#233;&#233;e?...)



=> regarde si tu as bien fait un WSAStartup...

cs_mayti · Answer

c'est l'erreur 000018af, la fen&#234;tre se cr&#233;e mais l'erreur arrive directement apr&#232;s.

simtiers · Answer

Je trouve pas l'erreur correspondant au code

=> une solution : cr&#233;e un log



#include <stdio.h>

FILE* log;



dans WinMain ou main :

log = fopen( "c:\log.txt", "wb+" );



A la fin de Winmain ou main (avt le return )

fclose( log );



Apr&#232;s chaque fct "critique" :

fputs( log, "Fct ... pass&#233;e sans probl&#232;mes
" );



Tu pourra identifier ce qui ne va pas

cs_aardman · Answer

Salut,
Il faudrait aussi afficher le numero d'erreur retourn&#233; par WSAGetLastError() dans ton log, sinon ca risque d'etre dur de savoir a partir de quel moment ca fonctionne plus.
