I am not that familar with RegEx. Can this been done with one replace call? Do you have an example?
|
|
|
|

This seems to work fine for me
string x = "123ABCD;233-";
x = System.Text.RegularExpressions.Regex.Replace(x, @"[^\w]", "");
This prints 123ABCD233;
You can Google for regexes that match more/less characters as you want.

Hi,
My program generates a log file for every event that happens in the program. So, I open the file and keep it open till the end. This is how I open the file for writing:
<br />
public CLogHandler()<br />
{<br />
this.m_fsLog = new FileStream(strTodaysLogFile, System.IO.FileMode.Append, System.IO.FileAccess.Write, System.IO.FileShare.Read);<br />
this.m_swLog = new StreamWriter(this.m_fsLog);<br />
if(this.m_swLog != null) this.m_swLog.AutoFlush = true; <br />
}<br />
<br />
pubic WriteLogMessage()<br />
{<br />
if(this.m_swLog != null) this.m_swLog.Write("[" + DateTime.Now.ToString("HH:mm:ss") + "] " + aMsg + Environment.NewLine);<br />
}<br />
One of the requirements is to display the current log file contents in a child form. So, I open the log file for reading like this :
<br />
System.IO.FileStream fs = new FileStream(this.m_strCurrentFileName, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.Read);<br />
System.IO.StreamReader sr = new StreamReader(fs);<br />
<br />
while(sr.Peek() > -1) this.DisplayLogText(sr.ReadLine() + Environment.NewLine);<br />
<br />
fs.Close(); <br />
As you see, when I open the file for writing, I'm granting FileShare.Read, which means other processes can open the file for reading. But when I try to open the file for reading, it gives IOException that the file is being used by another process.
So, how can we write and read to and from a file simultaneously in the same program (ofcourse, without stopping the write process)??
Cheers

The title says it all. I need to know if there is anyways to make a "copy" of a reference type.
So basically i want to know if there is a way to make a Reference Type variable act like a value type variable.
Or is the only way copy a reference type is to create a new one and then move all the info out of the old one into the new 
Thanks for your help!

It depends on the class of the variable. Some classes define a constructor that take another instance of the same class as a parameter. There's also a MemberwiseClone method, but note it's a protected method. Take a look at the ICloneable interface too.

That's how you do it. However, there are many ways to do that,
1. You can use MemberwiseClone.
2. Your object can implement ICloneable, implement the Clone method and do the copying there
3. You can use a nifty trick, serialize and deserialize the object back, you'll get a new copy and .NET handles all the copying for you.
private object Copy(object original)
{
using (MemoryStream ms = new MemoryStream())
{
BinaryFormatter fs = new BinaryFormatter(original.GetType());
fs.Serialize(ms, original);
return fs.Deserialize(ms);
}
}

3.
As I think he doesn't know serialization very well I would add the info that the class being copied needs to be marked as Serializable or implement the ISerializable interface.

You have to provide icon file in setup project properties.

You can do
static void Main()
{
Application.EnableVisualStyles();
Application.Run(new MainForm());
}
For more information, look here[^].

I am trying to get a second response from a Webrequest. The server that I am talking to works as follows.
First here is my code:
string postData = "";
Uri myUri = new Uri("http://208.XXX.XX.XXX:10224/?ReturnAddress=209.XX.XX.XX/recvpost.php");
HttpWebRequest h = (HttpWebRequest)WebRequest.Create(myUri);
h.Method = "POST";
h.ContentType="text/xml";
h.ContentLength=postData.Length;
Stream newStream = h.GetRequestStream();
newStream.Write(byte1,0,byte1.Length);
newStream.Close();
WebResponse resp = h.GetResponse();
StreamReader reader = new StreamReader(resp.GetResponseStream());
string str = reader.ReadLine();
while(str != null)
{
Console.WriteLine(str);
MessageBox.Show( str );
str = reader.ReadLine();
}
resp.Close();
1) Send your request, when received the replay "OK" will be sent.
2) Once the server has the request ready it will send the reply.
3) I am receiving the OK but nothing else.
How do you get secondary responses?

What do you mean by a second response? Each request can have only one response.

I was told by the server provider to send a Webrequest with the above mentioned header information. When the server receives the request it will send the OK reply, and then break the connection. When it has the reply ready it will call back on the ip address provided in the Uri and send the file noted in the Uri recvpost.php.
Uri myUri = new Uri("http://208.XXX.XX.XXX:10224/?ReturnAddress=209.XX.XX.XX/recvpost.php");
So, I guess I am asking how to I listen for that reply?
|
|
|
|

Ok you must be receiving as response code.. you have to receive webresponse stream to get the response form the requested uri.

|

If you look at my above code snippit isn't that what I am doing?
WebResponse resp = h.GetResponse();
StreamReader reader = new StreamReader(resp.GetResponseStream());
If you mean something different could you please clarify?
|
|
|
|
|
Then the data will be sent as a request to the php page.
