Environment.NewLine will definitely work I have used it several times.
Good Luck

Using Environment.Newline is the best practise. Also make sure the Multiline[^] property of the control is set to true

File System (about stream reader)

Syed Shahid Hussain2-Sep-06 22:30

2-Sep-06 22:30

I used a StreamReader and forgot to close it. Now when I try to do any file operation at that page(ASP.NET), I receive an Error message "file is using by another process". I have chaged the names of Variable,Text file and location but no success.

Any one can solve my problem.
Thanks

2- Is the a web application, or windows application?
3- Is your application on a localhost or a remote server?
4- Is your application in a debug or release mode?

Hello

Well, there are several ways of unlocking a shared file. It may take sometime to know who exactly is locking a certain file, but in your case you said you already changed the path in your code and variables, etc.. restarted you computer.. So to cut things short:

1- Restart in safe mode
2- Move the file to another location or delete it -I prefer backing it up first-
3- Restart in normal mode
4- Try you app
5- If it works, enjoy your life Smile | :)

BTW: If you need more help I suggest reposting your question in ASP .Net forum[^], maybe you get more help.

Also if it doesn't work, keep me posted.

Regards

Thanks Friend. But I had tired of it and I now I have made all new. I deleted the web page and txt file and develop a new page. I think it is the only solution of the situation. Now it is working correct. Thanks for your time.
God Bless You

hi all,
firstly: am i able to change the default icon for my setup and deployment project?
(not a shortcut's icon but 'the main setup.exe's icon')
>if yes, then let me know how i can do that please?

secondly: when i build my project, i see 2 different things in Debug folder: one is ***.msi and the other is setup.exe.
what is ***.msi ? why is that created beside setup.exe ?
when i copy these two things separately on my desktop: setup.exe cant be installed without ***.msi. cos i receive an error which tells me that setup.exe couldnt find **.msi.
but ***.msi itself can be installed without setup.exe ???

please inform me about two questions above ...

thanks in advance, bye.

Not that I know of! You can change the icon of the output of an ordinary WindowsApplication project. Not tyhe setup. Nop!
However if you hav an external Icon editor that has the capability of changing the icons of exe files. be my guest! Smile | :)

Mehmet Fatih Akbulut wrote:
what is ***.msi ?

This is the package file. That contains all the files and settings of your application.

Mehmet Fatih Akbulut wrote:

Actually it's the other way around. This is the main file in your whole project.

Mehmet Fatih Akbulut wrote:
setup.exe cant be installed without ***.msi

Sure! The Setup.exe only opens this package. It doesn't contain anything in itself.

Mehmet Fatih Akbulut wrote:

Because it contains all the necessary files and data to install your application on the user's machine, and if you double click on it, Windows Installer does the job for you.

Hi!
If you mean the icon you get under Add/Remove programs, then yes, you can set this icon in the properties of your setup project.
If you want to change the icon for setup.exe, you can simply open the file in VS using the resource editor. Then you can modify the resources (icons for examples) to your heart's desire.

Setup.exe is just a bootstrapper for the msi file. It checks whether the correct (and required) version of windows installer (3.0) is installed and if it isn't, it's trying to install it.

Afterwards, windows installer is told to install the msi file.

Newbie: The best way to detect the end of a data stream...

Hello all.. I am trying to construct a way of extracting data from a network stream.

However I am running into a small problem. I am using regex to detect a pair of return & newlines "\r\n\r\n". However some of the messages received have "\r\n\r\n" in the middle of the stream. So some of the messages are cut off halfway.

<br />
                byte[] ami_response_buffer = new byte[ami_buffer_size];<br />
                MemoryStream ami_memory_stream = new MemoryStream();<br />
                string ami_response = "";<br />
                int ami_bytes_read = 0;<br />
<br />
                do<br />
                {<br />
                    ami_bytes_read = ami_client_stream.Read(ami_response_buffer, 0, ami_buffer_size);<br />
                    ami_memory_stream.Write(ami_response_buffer, 0, ami_bytes_read);<br />
                    ami_response = Encoding.ASCII.GetString(ami_memory_stream.GetBuffer());<br />
<br />
                    // Check for end of message<br />
                    if (Regex.Match(ami_response, "\r\n\r\n", RegexOptions.IgnoreCase).Success)<br />
                    {<br />
                        ami_bytes_read = 0;<br />
                    }<br />
                }<br />
                while (ami_bytes_read > 0);<br />
                <br />
                return ami_response;<br />

What is the best way to detect the end of a data stream?

Thanks in advance...

keep reading until NetworkStream.DataAvailable becomes false.

I'm assuming that "\r\n\r\n" is the marker you are trying to use to indicate the end of the stream. You would want to do something like this:

string ami_response = "";

// Check to see if this NetworkStream is readable.
if (ami_client_stream.CanRead)
{
    byte[] ami_response_buffer = new byte[ami_buffer_size];
    MemoryStream ami_memory_stream = new MemoryStream();
    int ami_bytes_read = 0;
    
    myCompleteMessage = new StringBuilder();

    // Incoming message may be larger than the buffer size.
    do
    {
         ami_bytes_read = ami_client_stream.Read(ami_response_buffer, 0, ami_response_buffer.Length);
         myCompleteMessage.AppendFormat("{0}", Encoding.ASCII.GetString(ami_response_buffer, 0, ami_bytes_read));
                         
    }
    while (ami_client_stream.DataAvailable);
    
    ami_response = myCompleteMessage.ToString();
}

return ami_response;

Window is minimized after showing Splash Screen.

Hi,
My win form is always getting minimized after splash screen is shown and closed. Although my form's WindowState property is set to Normal. Is there any code piece I am missing to keep my original window STAND !!

Thanks.

/********************** My code ****************************/

public mainForm()
{

InitializeComponent();

th = new Thread(new ThreadStart(DoSplash));
th.Start();
}

private void DoSplash()
{
sp = new Splash();
sp.ShowDialog();
}

private void mainForm_Load(object sender, EventArgs e)
{

th.Abort();
}

Re: Window is minimized after showing Splash Screen.

2-Sep-06 12:13

Hello

1- First, the code above -AFAIK- shouldn't minimize your original form. Yet you might be missing something else somewhere!!

2- Second, the code above is a bit odd. Why do you call ShowDialog from another thread while simply you could just show the form in your own thread -make things simple!!-.

private void mainForm_Load(object sender, EventArgs e)
{
    Splash MySplash = new Splash();
    MySplash.Show();
    //Do Other loading processes
    //This.Hide(); if necessary!!
    MySplash.Close();
    //This.Show(); if necessary!!
}

I guess you are making a splash while loading your form -which might be a lengthy process in your case-. Maybe you minimized you main form somewhere while loading its UI?!!

Dear Nader,
the reson why you put a splashscreen in a separate thread is that otherwise the splashscreen isn't updated while the main thread is busy doing other things.
