You won’t be able to improve significantly performance while using .Net built in serializers. They are inheritably slow. I bumped into this many times. If performance is an issue I would recommend considering implementing custom destabilization (another word for “read you file and parse data in you code”).

Hello Ilia,
can you please give me any example or some link for cusuom deserialization to start of with it would be a great help

Well, what I basically recommend using StreamWriter, StreamReader class to write to file /read from the file data stored in your objects. The approach requires specifying format of the file and how pieces of the data stored / retrieved from the file.
When applied to your example is might look something like this
<code>
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.Serialization;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
using System.Diagnostics;
namespace ConsoleApplication1
{
public class CTempClass
{
public int m_uCrc64;
public int M_uCrc64
{
get
{
return m_uCrc64;
}
set
{
m_uCrc64 = value;
}
}
public CTempClass()
{
m_uCrc64 = 0;
}
}
class Program
{
static void Main(string[] args)
{
List<CTempClass> lsTemp = new List<CTempClass>();
for (int i = 0; i < 1000000; i++)
{
CTempClass oTemp = new CTempClass();
oTemp.m_uCrc64 = i;
lsTemp.Add(oTemp);
oTemp = null;
}
Stopwatch s = new Stopwatch();
s.Start ();
using (Stream stream = File.Open("c:\\data.bin", FileMode.Create))
{
BinaryWriter writer = new BinaryWriter(stream);
foreach (CTempClass instance in lsTemp)
writer.Write(instance.M_uCrc64);
writer.Close();
}
s.Stop();
System.Console.WriteLine ("Serialize " + s.Elapsed.TotalMilliseconds + " mils");
s.Reset();
s.Start();
byte[] buffer = File.ReadAllBytes ("c:\\data.bin");
lsTemp = new List<CTempClass>();
using (MemoryStream stream = new MemoryStream(buffer))
{
BinaryReader reader = new BinaryReader(stream);
try
{
while (true)
{
int i = reader.ReadInt32();
CTempClass oTemp = new CTempClass();
oTemp.m_uCrc64 = i;
lsTemp.Add(oTemp);
oTemp = null;
}
}
catch (EndOfStreamException)
{
reader.Close();
}
}
s.Stop();
System.Console.WriteLine("Deserialize " + s.Elapsed.TotalMilliseconds + " mils");
}
}
}

Does it work with a LineSpacingRule of "wdLineSpaceDouble"?
ravindra chintha wrote: but i cant getting sapce in b/w that adress...line by line..with spaces
The space is defined in your code with a LineSpacing of 0.7. That's also the suggested property according to this[^] article.
Does it help to decrease the value, or does changing the value have no effect at all?

Hello,
I want to build an application for writing text in textbox using speech recognition. i.e. if i speak "This is my first application" it should be displayed on textbox.
I have tried but failed. Here is my code.
System.Speech.Recognition.SpeechRecognitionEngine recognizer;
private void Form3_Load(object sender, EventArgs e)
{
recognizer = new System.Speech.Recognition.SpeechRecognitionEngine();
GrammarBuilder dictaphoneGB = new GrammarBuilder();
GrammarBuilder dictation = new GrammarBuilder();
dictation.AppendDictation();
dictaphoneGB.Append(new SemanticResultKey("StartDictation", new SemanticResultValue("Start Dictation", true)));
dictaphoneGB.Append(new SemanticResultKey("DictationInput", dictation));
dictaphoneGB.Append(new SemanticResultKey("EndDictation", new SemanticResultValue("Stop Dictation", false)));
GrammarBuilder spelling = new GrammarBuilder();
spelling.AppendDictation("spelling");
GrammarBuilder spellingGB = new GrammarBuilder();
spellingGB.Append(new SemanticResultKey("StartSpelling", new SemanticResultValue("Start Spelling", true)));
spellingGB.Append(new SemanticResultKey("spellingInput", spelling));
spellingGB.Append(new SemanticResultKey("StopSpelling", new SemanticResultValue("Stop Spelling", true)));
GrammarBuilder both = GrammarBuilder.Add(dictaphoneGB, spellingGB);
Grammar grammar = new Grammar(both);
grammar.Enabled = true;
grammar.Name = "Dictaphone and Spelling ";
recognizer.LoadGrammar(grammar);
recognizer.SetInputToDefaultAudioDevice();
recognizer.RecognizeAsync(RecognizeMode.Multiple);
recognizer.SpeechRecognized += OnSpeechRecognized;
}
private void OnSpeechRecognized(object sender, System.Speech.Recognition.SpeechRecognizedEventArgs e)
{
textBox1.Text = e.Result.Text;
}
There is no output.
Please help me i am new to speech recognition.
Thanks in advance.

Give us more information on your problem. You have an exception, no sound... ?
|
|
|
|
|
Thank you for reply.
And i am sorry for my late reply.
I am not getting any response from the application, if i speak into Mic there is no response, it does not go into the speech_recognized() event.
So i really don't understand what is going wrong.
Please help me.
Thanks in advance.

No sound, the problem may be the input device which is not the default one.
I will try to replay your sample

What is the error exactly? any body can explain?

Google gives loads of results for "error: 80040154" - MSDN[^] is probably the most usefull.

"Voice" authentication? You mean like checking whether the person who is speaking 'actually' sounds like the person trying to login?
Two questios;
- What do you do when a person has the flu?
- How do you plan to differentiate between the sound of a person and a pre-recorded sound?
Capturing speech is hard enough; you don't recognize a word, but map the sound to a list of words, sorted by confidence. We then present the top word of that list, claiming that the computer heard it.
Differentiating persons by the sound of their voice is a hard excercise which will take a fair amount of development-time.
