I've a c# application, I'm doing a final test of it. But now, a function which has worked everytimes until now doesn't work anymore! I've a Button, when I click on it I want to browse files, I see the "Open file" windows, and an half second after, I got an uncaught visual studio error: vshost32.exe has stopped working: I'm sorry but the error is happening on a french localized computer: Signature du problème : Nom d’événement de problème: APPCRASH Nom de l’application: TOM.vshost.exe Version de l’application: 10.0.30319.1 Horodatage de l’application: 4ba2084b Nom du module par défaut: ntdll.dll Version du module par défaut: 6.1.7600.16695 Horodateur du module par défaut: 4cc7ab44 Code de l’exception: c0000008 Décalage de l’exception: 0004631f Version du système: 6.1.7600.2.0.0.256.48 Identificateur de paramètres régionaux: 4108 Information supplémentaire n° 1: ffb6 Information supplémentaire n° 2: ffb61531feaa1f65f528a2694a510c22 Information supplémentaire n° 3: b220 Information supplémentaire n° 4: b2205da238309b0a025a25162a3a18f3 My code is: OpenFileDialog ofd = new OpenFileDialog {Filter = Filters}; if (ofd.ShowDialog() != true) { return; } it crash just when I'm in the ofd.ShowDialog. Is this a code related issue? Do you have any idea about how to debug? Or even how to debug this?? When activating the "unmanaged code to be debug", I got this: "First-chance exception at 0x77cd631f in TOM.exe: 0xC0000008: An invalid handle was specified." The stack trace if it could help: > ntdll.dll!77cd631f() [Frames below may be incorrect and/or missing, no symbols loaded for ntdll.dll] ntdll.dll!77d1792d() ntdll.dll!77ce343b() ntdll.dll!77ce2d80() ole32.dll!776b4102() ole32.dll!776b411e() ole32.dll!
