CLR Debugging API

Leave a comment

So in some advanced debugging situation, we have to write code to reflect the current managed variables and stacktrace.

John, Robbins mentioned in <Debugging with .Net 2.0 Application> as follow:

That’s really extremely excellent!!!

Clean internal session for Password in IE[or WebBrowser based on IE]

Flushes entries not in use from the password cache on the hard disk drive. Also resets the cache time used when the synchronization mode is once-per-session. No buffer is required for this option. This is used by InternetSetOption.

Windows 8 developer preview installation

Leave a comment

As you know, in windows 8 build conference [this 13- 16], Microsoft already unveiled Windows 8 developer version for us.

As I’m developer, so choose Windows Developer Preview with developer tools English, 64-bit (x64), about 5GB size.

  • Virtual system preparation:

Here, I introduce sun’s virtualbox as host, http://www.virtualbox.org/wiki/Downloads with version 4.1.2.

Let’s rock…

1, Create new virtual system

step 1 - Create new virtual system

step 2 - choose Windows 7 (64bit)

Step 3 - Create new virtual disk

Step 4 - Select Virtual Disk Type

Step 6 - Dynamic Disk Type

Step 7 – Create Virtual Disk with Dynamic Max Size

OK

OK, then we have to configure boot ISO and Visualization option [As 64 bit virtual system is required for Windows 8 64bit iso booting.]

And you have to enable your BIOS with Visualization option, if your computer couldn’t support visualization, I’m really sorry for you….

Step 8 - System Configuration

Step 8 - Mount your ISO disk

Step 9 - Select your iso

Step 10 - Rock Guys

2, Logging into your windows 8 system, change your screen resolution to larger than 1024. Then you can develop with your Visual studio 2011, with Grid/New application.

Screen shot for Windows 8

Update your screen resolution

Cheer up with Visual studio 2011

ToString() with Parameter and Parse/TryParse with parameters

Leave a comment

When using object.ToString(), or <primitive>.Parse(), TryParse(), any more ideas?

Ya… Es ist…

  1. Which language and Culture are you handling with?
  2. Do you want to format via IFormattable interface or parsing it?

MSDN Link :

  •   Help View Home/Visual Studio 2010/.Net Framework 4/.Net Framework Core Development/Working with Base Type/Formatting Types or Parsing Strings [strongly recommend]
  •   CLR via C# Version 3, Jeffery Richter – Page 309

Just shared with you the code.

C# STA Thread “Message Loop”

Leave a comment

seems a little bit impression, what’s the hell of Thread Message Loop.

  • Use Case – we have a STA DLL, which is exposed for us several COM/COM+ methods. And internally such DLL will store internal “status” cache, for instance STA instance, SA&G.
  • Key Points
  1. Explicit STA Thread construction – Thread.setApartment(STA/MTA). MTA is default setting.
  2. Supposed we call start(), and stop() for default instantiation logic of DLL, how about additional method called inside thread? Can we? Yes, just do something like Message loop. When performance has been concerned, EventWaitHandle (Mutex, Sep. etc)….

public class MethodProxyInThread
{
public MethodProxyInThread _realProxy;

private bool _isRealProxyStop = false;

private event EventHandler<EventArgs> _eventHandler;

private ThreadLocal<EventHandler<EventArgs>> _handler;

private Func<object, int> _functionalHook;

private EventWaitHandle waitHandle;

private object parameter;

/// <summary>
/// in one thread context
/// </summary>
/// <param name=”_realProxy”></param>
public void startMethod(object _realProxy)
{
if (this._realProxy == null)
{
this._realProxy = _realProxy as MethodProxyInThread;
this._isRealProxyStop = false;
Console.WriteLine(string.Format(“startMethod – {0}”, Thread.CurrentThread.ManagedThreadId));
Console.WriteLine(“startMethod”);

waitHandle = new EventWaitHandle(false, EventResetMode.ManualReset);
this._handler = new ThreadLocal<EventHandler<EventArgs>>(() => new EventHandler<EventArgs>(this.MethodProxyInThread__eventHandler));
this._eventHandler += this._handler.Value;

//TODO : Call start Method Here
//startCall() here
do
{
Console.WriteLine(string.Format(“loopMethod – {0}”, Thread.CurrentThread.ManagedThreadId));
if (this.waitHandle.WaitOne(5000))//rest if no more action, what time-out? to avoid deadlock!
{
//TODO : invoke conditional method; -> parameters
this._functionalHook.Invoke(this.parameter);//, null, null); //=>asynchorous logic
if (!this._isRealProxyStop)
{
this.waitHandle.Reset();
}
}
} while (!this._isRealProxyStop);
//stopCall() here
this._eventHandler -= this._handler.Value;
this.waitHandle.Close();
Console.WriteLine(“Quit the thread”);
}
}

private void MethodProxyInThread__eventHandler(object obj, EventArgs e) //Guys, why this isn’t working, delegation will be running in ThreadPool
{
Console.WriteLine(string.Format(“MethodProxyInThread__eventHandler – {0}”, Thread.CurrentThread.ManagedThreadId));
this._isRealProxyStop = true;
}

//public void PostTerminalEvent()
//{
//    if (MethodProxyInThread._eventHandler != null)
//    {
//        Console.WriteLine(string.Format(“PostTerminalEvent – {0}”, Thread.CurrentThread.ManagedThreadId));
//        MethodProxyInThread._eventHandler(this, new EventArgs());
//    }
//}

public void PostMessage(Func<object, int> _func, object _param)
{
if (!this._isRealProxyStop)
{
this._functionalHook = _func;
this.parameter = _param;

this.waitHandle.Set();
}
}

public void stopMethod()
{
Console.WriteLine(string.Format(“stopMethod – {0}”, Thread.CurrentThread.ManagedThreadId));
this._isRealProxyStop = true;
}
}

class Program
{
static int PostMessageObj(object _obj)
{
Console.WriteLine(string.Format(“postMethod – {0}”, Thread.CurrentThread.ManagedThreadId));
return 5;
}

static void Main(string[] args)
{
MethodProxyInThread proxy = new MethodProxyInThread();
Thread t = new Thread(proxy.startMethod);
t.Start(proxy);

Thread.Sleep(5000);
proxy.PostMessage(new Func<object, int>(Program.PostMessageObj), 6);
Thread.Sleep(5000);
proxy.stopMethod();
//proxy.PostTerminalEvent();
Thread.Sleep(10000);
}
}

 

Of Course, that’s not the ultimate version, For Message Loop, we need dictionary<enum, Func<object, object>> for checking-up, and parameter lists.

Like it, or some more suggestions… Whatever :-). No-UI SynchronizationContext Solution.
