Violation d'accès dans le programme Delphi ne peut trouver aucun indice

-4

J'ai une application Delphi à certains clients que je reçois une violation d'accès, mais je ne peux pas le reproduire ici sur plusieurs systèmes différents. Aussi un client a eu 2 ordinateurs identiques, sur un il arrive de l'autre pas.Violation d'accès dans le programme Delphi ne peut trouver aucun indice

L'exception se produit lorsqu'un formulaire est ouvert avec certains composants 3ème partie (mais j'essaie de les mettre à jour aussi bien), la forme est héritée d'un autre. Avec MadExcept, je reçois ce journal, mais cela ne semble pas m'aider non plus. Quelqu'un at-il une idée de ce que je peux essayer ensuite?

Nous n'obtenons aucun code? Eh bien, nous ne serons pas en mesure de vous donner une réponse. –

Regardez le désassemblage et déterminez quelle adresse n'est pas valide. –

Fournir un code simple qui reproduit le défaut peut être impossible. Pouvez-vous au moins décrire la structure de votre application? Utilise-t-il des threads? Vos formulaires sont-ils créés ou créés automatiquement à la volée? Des trucs comme ça nous donneraient un peu d'aide pour suggérer des façons de déboguer cela. –

Haut de la trace de la pile de madExcept est:

0064e033 +003 MyProgram.exe Vcl.Controls TWinControl.HandleNeeded

Vous devriez vraiment construire votre programme avec suffisamment d'informations pour obtenir des informations sur le numéro de ligne, mais +003 est suffisant. Démontez TWinControl.HandleNeeded et il ressemble à ceci:

Vcl.Controls.pas.12079: begin 
005659FC 56    push esi 
005659FD 8BF0    mov esi,eax 
Vcl.Controls.pas.12080: if WindowHandle = 0 then 
005659FF 83BE7802000000 cmp dword ptr [esi+$00000278],$00 
00565A06 7516    jnz $00565a1e

Les adresses diffèrent dans votre programme, mais le point est que 005659FF - 005659FC est le +003 offset. Ainsi, l'exception est dans la première ligne de la fonction:

if WindowHandle = 0 then

Le seul accès à la mémoire il y a la tentative de lecture du champ d'instance WindowHandle.

Et lorsqu'une lecture d'un champ d'instance échoue, cela signifie généralement que le pointeur d'instance est nil ou fait référence à une instance qui a déjà été détruite. Et puisque le texte d'exception déclare:

Lesen von Adresse 5AC03580

vous savez que le programme tente de lire l'adresse 5AC03580. Comme c'est loin de zéro, vous savez que le pointeur d'instance n'est pas nil. Ainsi, tous les signes pointent vers une instance qui a déjà été détruite.

Il n'y a aucun moyen pour nous de vous dire pourquoi vous avez une instance qui a été détruit. Maintenant, c'est votre travail de déboguer cela. Et s'il vous plait, ne soyez pas comme tant de demandeurs ici et attendez-vous à ce que nous disions plus que ce qui est humainement possible. Parfois, la réponse à une question est simplement de vous dire quoi faire ensuite.

Débogage doubles scénarios libres peuvent être un peu difficile, car ils ont tendance à être glissant. Vous ne rencontrerez pas toujours une exception d'exécution. Essayez d'utiliser un outil comme FastMM avec des options de débogage complètes activées, qui inclut des outils pour tenter de détecter les erreurs sans double.
