问题描述
我正在使用C#、. NET 4.0和DevExpress组件开发WinForms应用.
I'm developing WinForms app using C#, .NET 4.0, and DevExpress components.
在Windows 7上，一切正常.
On Windows 7 everything is working just fine.
在Windows XP SP3上，显示并关闭SaveFileDialog几秒钟后，应用程序将静默退出.
On Windows XP SP3,few seconds after SaveFileDialog is shown and closed, application will silently exit.
没有未处理的异常，应用程序退出事件不会触发，我只在Visual Studio输出窗口中收到消息:
There is no unhandled exception, Application exit event will not fire, I'm only getting message in the Visual Studio Output window:
The program '[3164] MyApp.vshost.exe: Managed (v4.0.30319)' has exited with code 0 (0x0).
导致此问题的代码非常简单:
Code that is causing this issue is very simple:
saveFileDialog1.ShowDialog();
您有任何想法为什么会这样吗?如何解决并解决此问题?
Do you have any ideas why is this happening? How can I troubleshoot and fix this?
推荐答案
在项目属性窗口中启用非托管调试.并确保将Visual Studio设置为在所有异常上都中断(检查Debug \ Exceptions菜单中的"Throw"选项).
Enable unmanaged debugging in the project properties window.And ensure that Visual Studio is set to break on all exceptions (check the "Throw" option in the Debug\Exceptions menu).
然后再次运行您的应用程序.VS现在应该打破异常-它应该是导致应用程序失败的shell扩展或文件处理程序.
Then run your application again. VS should now break on the exception - it should be a shell extension or file handler that's causing your app to fail.
