Аналогичная проблема.
При запуске SmartSample в debug-режиме под Visual Studio 2008
получаю Win32Exception "Access Denied"
at System.Diagnostics.ProcessManager.OpenProcess(Int32 processId, Int32 access, Boolean throwIfExited)
at System.Diagnostics.Process.GetProcessHandle(Int32 access, Boolean throwIfExited)
at System.Diagnostics.Process.Kill()
at Ecng.Trading.Smart.SmartTrader.KillSmartComProcess()
at Ecng.Trading.Smart.SmartTrader.OnConnect()
Если пускать .exe файл - ошибки нет.
Специально воспроизвел эту ошибку вызывая из тестового приложения OpenProcess для notepad.exe и для smartcom2.exe
Для первого все нормально даже в дебаге, для второго - под дебагом в VS - ошибка.
Порылся по форумам нашел решение (чтобы это ни значило, но работает).
Чтобы убивать любые процессы надо своему процессу поставить SeDebugPriviledge
Для этого нашел классик - см код ниже.
Для использования в SmartSample.MainWindow.MainWindow вставить Win32Helpers.SeDebugPriviledge.Enable();
Классик надо включить в проект примера.
Возможно Михаил включит в S# раз у нескольких людей такая ошибка вылетает
