Mati,
My experience of socket programming was on UNIX rather than Windows systems and was sometime ago, so I have probably forgotten quite a lot. I cannot really provide an online tutorial for you so I would repeat my earlier advice to go and study some tutorials and other publications before proceeding further. If you still have problems in the future then reopen your questions in the correct forum, as these are really not C# issues.
regards,
Richard

If it is difficult, then is there a portable compiler that I can use?

You compile it from the command line using csc.exe.

It's not difficult and more developers should learn to do it; it's a very useful tool to have.
When you install .net, the C# and VB.net compilers are installed as well (these are the same compilers that Visual Studio uses).
0. Open a DOS box; there are at least two ways to do this:
Start|Run cmd
Start|Programs|Accesories|Command prompt
Because I use a DOS box extensively I have it on my Quick launch toolbar
1. Determine which versions of the compiler you have:
C:\>dir /s /b "c:\windows\microsoft.net\framework\csc.exe
c:\windows\microsoft.net\framework\v1.1.4322\csc.exe
c:\windows\microsoft.net\framework\v2.0.50727\csc.exe
c:\windows\microsoft.net\framework\v3.5\csc.exe
C:\>
2. Execute the compiler of your choice, specifying your source code as a parameter:
C:\>c:\windows\microsoft.net\framework\v3.5\csc.exe Hello.cs
Microsoft (R) Visual C# 2008 Compiler version 3.5.30729.1
for Microsoft (R) .NET Framework version 3.5
Copyright (C) Microsoft Corporation. All rights reserved.
C:\>
3. Execute the program:
C:\>hello
Hello, world!
C:\>
4. If you do this frequently, you may want to write a BAT file to do this:
C:\>type csc.bat
@c:\windows\microsoft.net\framework\v3.5\csc.exe %*
C:\>
5. And/or add the compiler's directory to the Path environment variable
Start|Settings|Control panel|System|Advanced|Environment variables|System variables|Path|Edit

don't do it with notepad.
use the express version, microsoft intellisense is realy powerfull tool.
it helps you write code while you type it.
if you have coding experience with visual studio, please ignore this message.
but if you haven't, i couldn't imagen to memorize or search for all the properties a component/control or whatever has.

Use EditPlus?
You will still need the CSC.exe (Visual Studio) installed.

Doesn't csc.exe comes with the framework and not Visual Studio?

Why make life difficult for yourself? Get a copy of C# 2008 Express from Microsoft; it's a superb product and it is free. And if you still want to use Notepad and command line compile then check out the C# compiler pages on MSDN.

I need to develop a program that plays the signals which are arrived from an external device as follow. My problem is that there are artifacts in the onset and offset of each stream (sound.Play(data)).
what's the solution?
using System;
using System.Windows.Forms;
using Microsoft.DirectX.DirectSound;
using System.IO;
namespace TestSound
{
class CSound : Form
{
const int HEADER_SIZE = 44;
const bool FLAG_STEREO = true;
const short BITS_PER_SAMPLE = 16;
const int SAMPLE_RATE = 44100;
int numberOfSamples;
MemoryStream stream;
BinaryWriter writer;
Device ApplicationDevice = null;
SecondaryBuffer buffer = null;
BufferDescription description;
public CSound()
{
try
{
ApplicationDevice = new Device();
}
catch
{
MessageBox.Show("Unable to create sound device.");
ApplicationDevice = null;
return;
}
ApplicationDevice.SetCooperativeLevel(this, CooperativeLevel.Priority);
description = new BufferDescription();
description.ControlEffects = false;
stream = new MemoryStream();
writer = new BinaryWriter(stream);
}
private void AddHeader()
{
stream.Position = 0;
writer.Write(0x46464952);
writer.Write((int)(HEADER_SIZE + (numberOfSamples * BITS_PER_SAMPLE * (FLAG_STEREO ? 2 : 1) / 8)) - 8);
writer.Write(0x45564157);
writer.Write(0x20746d66);
writer.Write(16);
writer.Write((short)1);
writer.Write((short)(FLAG_STEREO ? 2 : 1));
writer.Write(SAMPLE_RATE);
writer.Write(SAMPLE_RATE * (FLAG_STEREO ? 2 : 1) * BITS_PER_SAMPLE / 8);
writer.Write((short)((FLAG_STEREO ? 2 : 1) * BITS_PER_SAMPLE / 8));
writer.Write(BITS_PER_SAMPLE);
writer.Write(0x61746164);
writer.Write((int)(numberOfSamples * BITS_PER_SAMPLE * (FLAG_STEREO ? 2 : 1) / 8));
}
public void Play(short[] samples)
{
if (ApplicationDevice == null)
return;
stream.Position = HEADER_SIZE;
numberOfSamples = samples.Length;
for (int i = 0; i < numberOfSamples; i++)
{
writer.Write(samples[i]);
if (FLAG_STEREO)
writer.Write(samples[i]);
}
AddHeader();
stream.Position = 0;
try
{
if (buffer != null)
{
buffer.Dispose();
buffer = null;
}
buffer = new SecondaryBuffer(stream, description, ApplicationDevice);
buffer.Play(0, BufferPlayFlags.Default);
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
}
}
public class Test
{
CSound sound = new CSound();
void Run()
{
short[] data;
port.Read(data);
sound.Play(data);
}
}
}
I think I should find a way to add new stream to current stream instead of destroying the current stream and creating new one(buffer.Dispose(); buffer = null; buffer = new...)
what's your suggestions?

Hi all,
I try to making a user control that show data from dataset, how I do for pass the dataset to any property and in other property display automaticaly all the fields of this dataset ??
Thanks in advance.

By implementing a DataSource propery and a DataMember property
Something like this:
private object dataSource = null;
private string dataMember = string.Empty;
[
Category("Data"),
Editor("SystemWindows.Forms.Design.DataMemberListEditor, System.Design", typeof(UITypeEditor))
]
public string DataMember
{
get
{
return this.dataMember;
}
set
{
this.dataMember = value;
}
}
[
Category("Data"),
AttributeProvider(typeof(IListSource)),
TypeConverter("System.Windows.Forms.Design.DataSourceConverter, System.Design")
]
public object DataSource
{
get
{
return this.dataSource;
}
set
{
this.dataSource = value;
}
}
It may be more complicated than this, but these are the basics. Look up any of the terms on MSDN for more detail.

I want to use taglib# in my serial id3 tagger (c) project, but I can't find out how to use/assign the taglib-libraries[^].
So where do I copy which files of the libraries and how do I assign them to my project? (as in: do I put using <k:\d\dev\taglib\taglib.h>; in the header?)

pietlut wrote: So where do I copy which files of the libraries
If you want to add project to solution copy files to solution folder, or yust copy dll to your project
pietlut wrote: how do I assign them to my project? (as in: do I put using <k:\d\dev\taglib\taglib.h>; in the header?)
Absolutly not that whay. This is not C++. Yust add to solution as exsisting project, then under main projet add reference to another project. Or you can yust copy dll files to your project, add reference to it and when you will run, those dll will be automatcly copied to same folder as exe file
And then you can use: using NameOfNameSpace;

this is a little bit tricky. write a wrapper for the function, what you want to use, using C++ .NET. Create that wrapper as a .NET DLL. Then add reference from C#. But it is not so easy, it is not for beginner.

You would add a reference to the taglib-sharp.dll to your project.

If you are using a header file, you are asking in wrong forum.

I am having a problem setting the x & y axis fontsize in MSChart. I have played with the settings through the properties window, but when I run it, nothing changes.
I can find out what the size currently is by typing:
float size = Chart1.ChartAreas["ChartArea1"].AxisX.TitleFont.SizeInPoints;
and that will bring up a size of 8. I do not know how to then set the size to something I want.
I've tried:
Chart1.ChartAreas["ChartArea1"].AxisX.TitleFont.Size.Equals(50);
which does nothing, and I've also tried
Chart1.ChartAreas["ChartArea1"].AxisX.TitleFont.SizeInPoints = 10;
which gives me an error of "Property or indexer 'System.Drawing.Font.SizeInPoints' cannot be assigned to -- it is read only"
So does anyone know what I can type to set the axis? Thanks for your help!

Hi,
in .NET some properties are read-only, i.e. you can get them but not set them.
Most often then there also is a "bigger" property that can be set.
Example: Form.Width is not settable, Form.Size is settable.
In your particular case you have to set a new TitleFont.

That makes sense, but I'm not sure how to do that b/c TitleFont is not a type. Could you give me an example?
|
|
|
|

Sorry no, I never used MSChart. Anyway, isn't TitleFont holding a Font instance?

Its got a FontFamily, but once again, its a get property, does not have any set properties. I'll see if I can tinker with it some more and figure it out. Thank for your help!
