INTERNET_OPTION_END_BROWSER_SESSION

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.

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.

static void IFormatProviderTest()
{
//foreach (CultureInfo item in System.Globalization.CultureInfo.GetCultures(CultureTypes.AllCultures)) //CultureTypes Enumeration
//{
//    Trace.WriteLine(item.ToString());
//}
decimal lNumericBase = 10000000L;//Int64->long
Trace.WriteLine(lNumericBase.ToString(“C”, new CultureInfo(“de-DE”)));
//Trace.WriteLine(lNumericBase.ToString(“D”, new CultureInfo(“de-DE”))); //Invalid format
Trace.WriteLine(lNumericBase.ToString(“N”, new CultureInfo(“de-DE”)));

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.

Animation Effect adjustment of WPF

Leave a comment

Refer from Adam, Nathan’ WPF unleashed for 3.5.

  • System.windows.Media.RenderCapacity -> static property Tier and TierChanged event

Tier is 32bit int number, however, the real value is stored in the higher 16 bytes.

int tier = RenderCapability.Tire>>16;

if tier == 0, system will use software rendering;

if tier == 1, system will use hardware rendering sometimes;

if tier == 2 [highest level], system will use hardware rendering, wherever graphic could be rendered by hardware.

-> esp. in tier == 0 system, will be difficult to run multi-animation[with 3D effect or complicated transition] .

  • So how-to for tier == 0 system, 1, remove Animation; 2, eliminate DesiredFrameRate of Storybard[normal case = 60frames/second],
