“Program has encountered an error” vs “Unhandled exception”

Question

I have created a program that I have released online. I have tried to handle all the exception , but sometimes the program still has crashes. But when I reproduce the crash on my side, it says: "Unhandled exception has occurred in your application". The users of my program see "The program has encountered a problem" and a little bar comes up with text above it "Looking for solution".

Do I see a different window to the users because I have the full development environment installed and they just have the runtime? And is there a way to save the DEV state of the program when it crashes or bring up a message saying: "The program has crashed, would you like to send details to the developer" or something like that?

Answer 1

我建议将事件处理程序添加到Application.ThreadException和AppDomain.CurrentDomain.UnhandledException以在那里实现常规错误处理。

Answer 2

Sounds like you're developing for windows. The crash your users are seeing is different presumably because when you're running it you have a debugger attached.

What you could do is download the "Microsoft Ecosystem Metadata Exchange" (MEME) program from https://sysdev.microsoft.com/ , by logging in with your MSDN account, you should be able to find the download.

The "Looking for solution" dialog is sending minidumps to sysdev.

• register your binaries with the MEME tool
• check out sysdev site for your minidumps
• open minidump with visual studio and select your binary
• you're in debug mode broken at the exception.
• inspect call stack
• profit
