Garbage Collector

Now i won't deal with the theory.
just a brief look on code.
To force GC to collect the candidate to dispose

GC.collect();

GC.WaitForPendingFinalizers();
This will make GC wait for all of the finalizer of every suspected object to be called

You can override finalizer with short key ~
~thenameoffinalizer()
{
//do something
}

The right thing to write on the so When calling finalizer also call dispose
~Thing()
{
Dispose();
//Do something on finalizer
}
can do try catch, if error register again to finalize with this command
GC.ReRegisterForFinalize(t);

There are also to check the total memory method on GC.
long G =GC.GetTotalMemory(true);

Live from Lumpur Lapindo, Sidoarjo

I've gone to this Lumpur lapindo, at porong sidoarjo.penulis adalah org jkt yang hanya mendengar dari berita sblmnya.
sekarang tempat ini sudah menjadi tempat wisata. parkir motor 2000, masuk 3000/org.
disana pada tepian pertama anda akan melihat 2 atau 3 kolam besar di bawah anda. ada yang satu kolam itu sudah menjadi keras, seperti tanah kering retak2.dan anda lihat
ada penangkal2 petir , ujung tiang masjid.2 atau 3 desa lenyap di bawah kolam itu. lalu dgn membayar 10.000 anda di antar ke 2 titik, ke kolam utama dan ke sebelah kanan, tempat semburan baru. di Tempat semburan baru.. anda lihat gelembung2 . "Semenjak bola2 beton di lemparkan ke pusat semburan, tanah itu kan seperti rongga, jadi malah di kolam2 bawahnya terjadi pusat semburan baru(blub blub blup)" keterangan tour guide.
Tour guide juga menunjukkan rumah Marsina kasus marsina yg memperjuangkan hak teman2nya dan ditembak oleh TNI "mungkin ini pembalasan Marsina" ,cetus tourguide.Juga ada rumah doyok yang tenggelam.
di samping kiri kolam utama anda lihat bahwa tanggulnya jebol, atas nya keras tapi tengah2 mengalir terus lumpurnya dan juga Pipa AWAL yang jebol/meledak, asal mula lumpur. "LUMPUR INI AKAN TERUS MENGALIR 30 tahun lagi"
Sepanjang jalan porong kini sudah seperti Kota hantu, tidak berpenghuni , bank2 tidak beroperasi dan Flyover jalan tol di hancurkan, dan bau belerang / sulfur di mana2.
semua tanah di sana di black list gak bisa jadi pinjaman.
Menurut tour guide yg jg adlh warga sidoarjo yg menjadi korban, "Banyak warga yang sudah mati Karena stress , terutama yang tua2".

rencana ingin dialirkan ke kali porong diprotes warga, bygkan. . .kalo masuk ke kali

Kemanakah akan dialirkan lumpur ini?? 30 tahun lagi?
Berduka untuk Porong . . . .

Code Generator Example

// Set up our assembly and module builders:

string outFilename = "foo.exe";

AssemblyBuilder ab = AppDomain.CurrentDomain.DefineDynamicAssembly(

new AssemblyName("foo"), AssemblyBuilderAccess.Save,

AppDomain.CurrentDomain.Evidence);

ModuleBuilder mb = ab.DefineDynamicModule(ab.FullName, outFilename, false);

// Create a simple type with one method:

TypeBuilder tb = mb.DefineType("Program",

TypeAttributes.Public | TypeAttributes.Sealed, typeof(object));

MethodBuilder m = tb.DefineMethod("MyMethod",

MethodAttributes.Public | MethodAttributes.Static);

// Now emit some very simple "Hello World" code:

ILGenerator ilg = m.GetILGenerator();

ilg.Emit(OpCodes.Ldstr, "Hello, World!");

ilg.Emit(OpCodes.Call,

typeof(Console).GetMethod("WriteLine", new Type[] { typeof(string) }));

ilg.Emit(OpCodes.Ret);

// Lastly, create the type, set our entry point, and save to disk:

tb.CreateType();

ab.SetEntryPoint(m);

ab.Save(outFilename);

 

For all of you who have example on LGC for 2.0 Please Post!!!

Drag n Drop on Control

Set the control property Allowdrop=true.

When mouse down thecontrol.Dodragdrop(object,DragdropEffectsEnum)

DragdropEffects.Copy | Move | ALL | None | Link | Scroll

and then on the control that you want to drop

put the logic on Drag Enter And Drag Drop

set the drag enter e.effect

and put the logic when data is drop.

 

 

Validating XML with DTD or XSD

public void ValidateXMLagainstDTD(Stream thestream)

{

XmlTextReader reader = new XmlTextReader(thestream);

XmlValidatingReader validator = new XmlValidatingReader(reader);

validator.ValidationType = ValidationType.DTD;

validator.ValidationEventHandler += new ValidationEventHandler(DTDValidationEventHandler);

while (validator.Read())

{

//add something logical here

}

validator.Close();

if (Isvalid)

Console.WriteLine("Document is valid");

else

Console.WriteLine("Document is Invalid");

Console.ReadLine();

}

public void DTDValidationEventHandler(object sender,

ValidationEventArgs args)

{

this.Isvalid = false;

Console.WriteLine("Validation event\n" + args.Message);

}

Create XML through XmlWriterSettings => the fastest,efficient way instead using DOM

public static MemoryStream CreateXMltoStream(string emailsubject,string emailfrom,string emailto)

{

MemoryStream stream=new MemoryStream();

XmlWriterSettings thesettings = new XmlWriterSettings();

//writing to stream default is UTF8

Encoding x=System.Text.Encoding.GetEncoding("ISO-8859-1");

thesettings.Encoding = x;

thesettings.Indent = true;

//Write the header

thesettings.OmitXmlDeclaration = false;

thesettings.NewLineOnAttributes = true;

using (XmlWriter writer = XmlWriter.Create(stream, thesettings))

{

writer.WriteRaw(@"<!DOCTYPE MEDVRI_1 SYSTEM ""MEDVRI_1.dtd"">");

writer.WriteStartElement("MEDVRI_1");

writer.WriteStartElement("email");

writer.WriteStartElement("email.subject");

writer.WriteValue(emailsubject);

writer.WriteEndElement();

writer.WriteStartElement("email.from");

writer.WriteValue(emailfrom);

writer.WriteEndElement();

writer.WriteStartElement("email.to");

writer.WriteValue(emailto);

writer.WriteEndElement();

writer.WriteEndElement();

writer.WriteEndElement();

//free the memory

writer.Flush();

writer.Close();

return stream;

}

 

 

WSE 3.0

What is the use of WSE? WSE create a filter and security policy making kind of tunnel so what ever request go to that pipeline.

It can secure the server, and client app. make sure each of them using the correct policy.

there are usernamepolicy , certificate policy, and you can add an authorize one. Can do a custom policy too

What is good on learning this is WSE Hands on Lab,you’ll find the basic and advanced.

 

List

What is actually List , Generic or T, it means that this has not yet been bound to a type argument.What differs from List for example, is that the List means it has been fully constructed,each of it's parameter has been bound.

Partially constructed generic type example:
class StringKeyDictionary : Dictionary { }

How Does Reflection Detect This Paramater is Generic?

namespace PrintTypeParamsss
{
class Program
{
static void Main(string[] args)
{
PrintTypeparams(typeof(List<>));
PrintTypeparams(typeof(List));
PrintTypeparams(typeof(Dictionary));
PrintTypeparams(typeof(Dictionary));
PrintTypeparams(typeof(Nullable<>));

Console.ReadLine();
}
static void PrintTypeparams(Type t)
{
Console.WriteLine(t.FullName);
foreach (Type ty in t.GetGenericArguments())
{
Console.WriteLine("--> {0} {1} {2}",
ty.FullName,
ty.IsGenericParameter,
ty.IsGenericParameter ? ty.GenericParameterPosition : 0);
};

}
}
}

Property Info

namespace PropertyInfossss
{
public class Test
{
private string _Test;
public string Name
{
get { return _Test; }
set { _Test = value; }
}
}
class Program
{


static void Main(string[] args)
{
PropertyInfo a=typeof(Test).GetProperty("Name");
Console.WriteLine("Read:" + a.CanRead + " Write:" + a.CanWrite + " Type:" + a.PropertyType);
MethodInfo theSetMethod = a.GetSetMethod();
MethodInfo theGetMethod = a.GetGetMethod();
MethodBody theSetMethodBody= theSetMethod.GetMethodBody();
MethodBody theGetMethodBody= theGetMethod.GetMethodBody();


}
}

PE and Platform Kinds

Assembly a = Assembly.GetExecutingAssembly();
Module m = a.ManifestModule;
PortableExecutableKinds peKinds;
ImageFileMachine imageFileMachine; m.GetPEKind(out peKinds, out imageFileMachine);

if ((peKinds & PortableExecutableKinds.ILOnly) != 0)
{
   // Assembly is platform independent.
}
else
{
   // assembly is platform dependent
   switch (imageFileMachine)
   {
       case ImageFileMachine.I386:
           // i386, x86, IA-32, ... dependent.
           break;
       case ImageFileMachine.IA64:
           // IA-64 dependent.
           break;
       case ImageFileMachine.AMD64:
           // AMD-64, x64 dependent.
           break;
   }

}
