我有一种很好的方式来捕获未处理的异常，这些异常会显示给我的用户并（可选地）通过电子邮件发送给我自己。它们通常看起来像这样：

Uncaught exception encountered in MyApp (Version 1.1.0)!

Exception:
   Object reference not set to an instance of an object.
Exception type:
   System.NullReferenceException
Source:
   MyApp
Stack trace:
   at SomeLibrary.DoMoreStuff() in c:\projects\myapp\somelibrary.h:line 509
   at SomeAlgothim.DoStuff() in c:\projects\myapp\somealgorithm.h:line 519
   at MyApp.MainForm.ItemCheckedEventHandler(Object sender, ItemCheckedEventArgs e) in c:\projects\myapp\mainform.cpp:line 106
   at System.Windows.Forms.ListView.OnItemChecked(ItemCheckedEventArgs e)
   at System.Windows.Forms.ListView.WmReflectNotify(Message& m)
   at System.Windows.Forms.ListView.WndProc(Message& m)
   at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

是否可以启动视觉工作室并c:\projects\myapp\somelibrary.h在违规线路上打开它，如果可以，如何？

如果可能的话，我还想从我生成的 (html) 电子邮件中执行此操作？

您可以自动化 Visual Studio，例如使用 VBScript：

filename = Wscript.Arguments(0)
lineNo = Wscript.Arguments(1)

' Creates an instance of the Visual Studio IDE.
Set dte = CreateObject("VisualStudio.DTE")

' Make it visible and keep it open after we finish this script.
dte.MainWindow.Visible = True
dte.UserControl = True

' Open file and move to specified line.
dte.ItemOperations.OpenFile(filename)
dte.ActiveDocument.Selection.GotoLine (lineNo)

将其保存为 saydebugger.vbs并运行它，将文件名和行号作为命令行参数传递：

debugger.vbs c:\dev\my_file.cpp 42

由于您的问题被标记为 C++，因此这里有一些使用该语言的代码来实现这一点；与乔恩的答案基本相同，但更多文字..

bool OpenFileInVisualStudio( const char* psFile, const unsigned nLine )
{
  CLSID clsid;
  if( FAILED( ::CLSIDFromProgID( L"VisualStudio.DTE", &clsid ) ) )
    return false;

  CComPtr<IUnknown> punk;
  if( FAILED( ::GetActiveObject( clsid, NULL, &punk ) ) )
    return false;

  CComPtr<EnvDTE::_DTE> DTE = punk;
  CComPtr<EnvDTE::ItemOperations> item_ops;
  if( FAILED( DTE->get_ItemOperations( &item_ops ) ) )
    return false;

  CComBSTR bstrFileName( psFile );
  CComBSTR bstrKind( EnvDTE::vsViewKindTextView );
  CComPtr<EnvDTE::Window> window;
  if( FAILED( item_ops->OpenFile( bstrFileName, bstrKind, &window ) ) )
    return false;

  CComPtr<EnvDTE::Document> doc;
  if( FAILED( DTE->get_ActiveDocument( &doc ) ) )
    return false;

  CComPtr<IDispatch> selection_dispatch;
  if( FAILED( doc->get_Selection( &selection_dispatch ) ) )
    return false;

  CComPtr<EnvDTE::TextSelection> selection;
  if( FAILED( selection_dispatch->QueryInterface( &selection ) ) )
    return false;

  return !FAILED( selection->GotoLine( Line, TRUE ) ) );
}
