Thanks for replying all.
So just to recap. Are we in agreement that the old way of dotting the code with
debug/trace statements is how developers figure out how code works and fix bugs?

Dear All,
I have windows service build in c# and it does some actions.
it has got a single method which prints text and this method is called from different classes.
now i want to print all the messages as they are printed, in Windows Application.
I can print these messages into EventLog or in Console.WriteLine(string msg)
any ideas how to capture all these message as the are printed into a windows application (WinForm)?Abdul Rahaman Hamidy

This[^] should probably help.

Thanks for the reply, link show how to store output or messages to EventLog. but i want how retreive those messages which i am printing in that method.
this I have seen in Sql Sever Agent. as I think SQL SERVER Agent is a service and you can see the messages or the outputs in SQL SERVER Synchronization "Replication" Status.
I want just the same thing to perform in C#. Like i have a service build in C# and when ever a message is printed that should be shown in Winform Application.Abdul Rahaman Hamidy

Hi all. I have a client-server distributed system. I want to transfer and image from the server to the client. In the server i have converted a .bmp image to byte array as this:
Image imageIn = Image.FromFile("me.bmp") ;
MemoryStream msr = new MemoryStream();
imageIn.Save(msr, System.Drawing.Imaging.ImageFormat.Gif);
byte[] byteIm = msr.ToArray();
ms.Send(byteIm);
The bytes are being transfered okay to the client. The problem is that i don't know how to assemble this byte back to an image to show in a picture box.
That is:
pictureBox1.Image =

have a look at this[^] You should never use standby on an elephant. It always crashes when you lift the ears. - Mark Wallace

Actually that is where i knew how to convert and image to bytes but the function returning an Image, how will the pictureBox get the URL? Wamuti: Any man can be an island, but islands to need water around them!

Why would the picture box want a URL? Just give it the image, or save it to disk and then give it the url as the file location.
From your original code:
MemoryStream ms = new MemoryStream(byteArrayIn);
pictureBox1.Image = Image.FromStream(ms);

Here you go:
MemoryStream memStream = new MemoryStream(imageBytes);
Image image = Image.FromStream(memStream);

Thanks guys. It worked. Wamuti: Any man can be an island, but islands to need water around them!

try following code:
private void Button2_Click(object sender, System.EventArgs e)
{
connection.Open();
SqlCommand command1 = new SqlCommand("select imgfile from myimages where imgname=@param", connection);
SqlParameter myparam = command1.Parameters.Add("@param", SqlDbType.NVarChar, 30);
myparam.Value = txtimgname.Text;
byte[] img = (byte[])command1.ExecuteScalar();
MemoryStream str = new MemoryStream();
str.Write(img, 0, img.Length);
Bitmap bit = new Bitmap(str);
Response.ContentType = "image/jpeg";//or you can select your imagetype from database or directly write it here
bit.Save(Response.OutputStream, ImageFormat.Jpeg);
connection.Close();
}
change your database name, field name, image name, attribute name.
If You Get your answer then please Rating me...
Thanks..

As you have seen system encodings, ASCII or UTF. I want to create my own, like some value for some specific character. So to do that I simple make a Character class and a collection to hold 'em. But when I need to convert a value to char it iterates the collection until that value is found and thats too slow. But I have another idea which I have tried and also reached nearby the same performance as Encoding.GetString.
So any suggestions guys ?

If it is a small set of values then set up an array of translations - index is the character to translate.
If the set gets big, then put the array into a file and read it on start up. You would need two arrays if you want to go both ways.
Memory is not a major problem these days, so that would be the fastest way.You should never use standby on an elephant. It always crashes when you lift the ears. - Mark Wallace

thats exactly what I thought but there is a problem, It will be faster from value(index) to char but what about char to value ??

You can also index an array with a char, or isn't that what you meant?

example ?

you mean like this ?
short[] values = new short[count];
short[] chars = new short[count];
values[(int)'c'] = value;
chars[value] = 'c';

You don't need to cast the char to an int
|
|
|
|

its not dictionary, its an array

It doesn't matter, indexing an array with a char works just as well

nice, never noticed.
Thanks btw

Works fins just with a char:
int[] array = new int[256];
Random r = new Random();
for (int i = 0; i < 256; i++)
{
array[i] = r.Next(256);
}
string s = "Hello there!";
int[] output = new int[s.Length];
int ind = 0;
foreach (char c in s)
{
output[ind++] = array[c];
}
}
