Re: Debugging unmanaged DLL called from managed C# stancrm21-Jul-09 3:23 stancrm 21-Jul-09 3:23  Have you tried this one ? http://social.msdn.microsoft.com/Forums/en-US/vsx/thread/91232ee3-a70c-43e4-b9f2-f8ff860c60ca/[^] Re: Debugging unmanaged DLL called from managed C# Chesnokov Yuriy21-Jul-09 3:42 Chesnokov Yuriy 21-Jul-09 3:42  that one worked, 'Enable just my code debugging'. Great!!! Чесноков Re: Debugging unmanaged DLL called from managed C# Chesnokov Yuriy21-Jul-09 4:04 Chesnokov Yuriy 21-Jul-09 4:04  however you still can not run native DLL which is invoked in C# and stop at bps in DLL project Чесноков Re: Debugging unmanaged DLL called from managed C# Chesnokov Yuriy22-Jul-09 20:37 Chesnokov Yuriy 22-Jul-09 20:37  I've got all setup as described and was debugging native DLL normally, while on the other project run it just stopped stepping into the native DLL? What happened as I did not touched the settings they were before??? Чесноков Acess violation exception before Main?!? Olivier Gautherot21-Jul-09 2:08 Olivier Gautherot 21-Jul-09 2:08  Hi, I have a small application that is exhibiting an AccessViolationException before it even enters Main(). I found this out after the pilot in our production environment started failing from time to time - it would enter some infinite loop somewhere at the end of Main() after all useful code has been executed. I found the access violation when running the app in the debugger. The tricky bit is that it does not happen in controlled source code (the failure occurs before I reach Main()) so the actual issue is difficult to determine. I would suspect some kind of stack overflow but do to know how to troubleshoot this in Visual Studio. The app is in C#. Any suggestion to get started? Re: Acess violation exception before Main?!? Olivier Gautherot21-Jul-09 2:58 Olivier Gautherot 21-Jul-09 2:58  Maybe one more detail: it is a console app and is complaining about a Windows Form (in an attempt to issue a SendMessage()). However, I do not have explicit instantiations of a Windows Form... Weird... Re: Acess violation exception before Main?!? stancrm21-Jul-09 3:01 stancrm 21-Jul-09 3:01  How about in project properties -> output type ? It must be "Console Application". Re: Acess violation exception before Main?!? Olivier Gautherot21-Jul-09 3:04 Olivier Gautherot 21-Jul-09 3:04  It is. .NET target is also set to 2.0 for the production environment. Re: Acess violation exception before Main?!? stancrm21-Jul-09 2:59 stancrm 21-Jul-09 2:59  Have you tried to reinstall .NET Framework and run it as administrator ? Re: Acess violation exception before Main?!? Olivier Gautherot21-Jul-09 3:03 Olivier Gautherot 21-Jul-09 3:03  Mmmhhh... interesting thought. No, I haven't. However, I have already 2 machines with some kind of symptom. The production environment is under .NET 2.0 and my machine under 3.5. The project targets specifically 2.0. Hope this helps Re: Acess violation exception before Main?!? stancrm21-Jul-09 3:06 stancrm 21-Jul-09 3:06  My developing PC is also .NET 3.5 with VS2008, and the production system is XP with .NET 2.0. It works great... without any problem. Re: Acess violation exception before Main?!? Olivier Gautherot21-Jul-09 3:13 Olivier Gautherot 21-Jul-09 3:13  It worked for me too at the beginning - that's why I don't think this is the issue. It sounds like I'll have to create a new project and import my current code until it breaks... Re: Acess violation exception before Main?!? Luc Pattyn21-Jul-09 3:10 Luc Pattyn 21-Jul-09 3:10  Hi, your static Main() method is inside some class; the static constructor of that class, if any, will run first. As a console app, chances are all/most/large parts of your code are in that class. I suggest you move them out, keep the class containing static Main() as simple as possible, put everything else in another class, either static or instantiated once. That will ease your debugging.

Olivier Gautherot21-Jul-09 3:16 Olivier Gautherot 21-Jul-09 3:16  Sounds like a good plan. Yes, I have a few things in the main class. I'll have a look tonight. Thanks! Re: Acess violation exception before Main?!? Olivier Gautherot22-Jul-09 1:33 Olivier Gautherot 22-Jul-09 1:33  Hi Luc, In the end, I tried to create a new console project with just an empty Main() and tried to step into it - I can't figure out how to remove more from the main class... I tried to step into Main() and had the same AccessViolationException error about Windows.Forms. So I gave up and am trying to reinstall VisualStudio. It's weird... and I could have a better use of my time then trying to correct M$ errors... I'm under Vista SP2 (well, Windows still thinks that it is under SP1 - the machine is brand new and Windows is having problems since I tried to load SP2). Just hope I won't have to reinstall the whole machine from scratch. Re: Acess violation exception before Main?!? Luc Pattyn22-Jul-09 1:37 Luc Pattyn 22-Jul-09 1:37  I would run first outside Visual Studio, and try on a second PC. If it behaves badly outside VS and only on one machine, then I would reinstall the .NET Framework on that machine, rather than reinstalling/fixing VS. If it runs fine outside VS, or badly on both machines, then I would reinstall VS.

Olivier Gautherot22-Jul-09 3:03 Olivier Gautherot 22-Jul-09 3:03  I tried to reinstall VS but no luck: it is still not able to debug a freshly created console project I'm frustrated because I just bought a new machine to run as my development machine and VS won't run properly. I've spent a week setting it up and it looks like I'll have to restart the process - and, meanwhile, I can't finish my current project (which is becoming urgent). Why do things have to be so complicated with Windows?!? Re: Acess violation exception before Main?!? Olivier Gautherot27-Jul-09 3:43 Olivier Gautherot 27-Jul-09 3:43  Issue fixed: since I had issues with the Windows updates, I finally had to reinstall the whole machine from scratch - which now works! I'll be able to retake my productive work. Thanks for your support Olivier Re: Acess violation exception before Main?!?

Olivier Gautherot22-Jul-09 1:41 Olivier Gautherot 22-Jul-09 1:41  Well, it runs fine on my machine outside the debugger - that's why I suspect VS has an issue. I should know in a few minutes now.

The idea here is to pass the username and password in a function as argument so that this function will automatically enter both (username and password) once the Windows dialog box for Aithentication pop ups while accessing a share in any other system. Can you please help me out with any API or any other piece of code to work out!
