hi,
i have a problem regarding this piece of code it throw an exception ("time out expired ") can anyone tell me why
<br />
try<br />
{<br />
Stream reqStream = webRequest.GetRequestStream();<br />
reqStream.Write(requestBytes,0,requestBytes.Length);<br />
reqStream.Close();<br />
HttpWebResponse webResponse=(HttpWebResponse)webRequest.GetResponse();<br />
if (webRequest.HaveResponse)<br />
{<br />
foreach(Cookie retCookie in webResponse.Cookies)<br />
{<br />
bool cookieFound = false;<br />
<br />
foreach(Cookie oldCookie in ccContainer.GetCookies(destination))<br />
{<br />
if (retCookie.Name.Equals(oldCookie.Name))<br />
{<br />
oldCookie.Value = retCookie.Value;<br />
cookieFound = true;<br />
}<br />
}<br />
if (!cookieFound)<br />
ccContainer.Add(retCookie);<br />
<br />
} <br />
if ((webResponse.StatusCode == HttpStatusCode.Found) || <br />
(webResponse.StatusCode == HttpStatusCode.Redirect) ||<br />
(webResponse.StatusCode == HttpStatusCode.Moved) ||<br />
(webResponse.StatusCode == HttpStatusCode.MovedPermanently))<br />
{ <br />
WebHeaderCollection headers = webResponse.Headers;<br />
return SendRequestTo(requestBytes,new Uri(headers["location"]),credential); <br />
}<br />
StreamReader stream = new StreamReader(webResponse.GetResponseStream());<br />
string responseString = stream.ReadToEnd();<br />
stream.Close();<br />
return responseString;<br />
}<br />
throw new ApplicationException("No response received from host.");<br />
}<br />
catch(WebException e)<br />
{<br />
Trace.WriteLine("Exception occured " + e.Message);<br />
throw new ApplicationException("Exception occured while sending request.",e);<br />
}

If "time out expired" is the exception text, then that is the reason your code has a problem. Try changing "e.Message" to "e.ToString()" so you know which line had the problem (you might get a little bit more information, too).
Some of the basic reasons for a timeout are that the server isn't up, you have a bad address, or your connection to the server has been interrupted somewhere along the way.

Hey!
If i create a byte[] like this
<br />
byte[] tmpData = new byte[1024];<br />
tmpData will have 1024 elements, all set to "0"
The data i will add to this byte array could be 0 how do i now what place i shold write on next time?
ex
first write
element 0 1 2 3 4 5 6 7 8 9 10 11 12 13
data 24 0 5 21 6 4 14 2 9 18 0 5 4 0
if i then whant to add more data to this byte[], how do i know that element 14 is the next place to add data if a regular element in the byte[] is 0?
Maby i could set all elements to -1 on creation, and then test against this, but this will be alot of test(preformance).
I could also store a extra int that keeps track of where to write the next turn, but this will be som extra class and vaibels.
Is there another way to do this?
Best Regards
SnowJim

The best way to do it is to track the index number that you last wrote to. If you have to try and find the last element, which you've already said you really can't do anyway, that's just overhead your adding searching through the array. It doesn't look like you have much of a choice here...

Thanks!
i Think i will do this another way, all the oporations i will have to do with this byte array will probely take more preformance.
BestRegards

See the documentation on the Process class, here[^] on MSDN.

To start a process (e.g. Notepad) you could say something like:
using System.Diagnostics;<br />
.<br />
.<br />
.<br />
<br />
Process myProcess = new Process();<br />
myProcess.StartInfo.FileName = "Notepad";<br />
myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Maximized;<br />
myProcess.Start();

hi guys,
can anyone tell me how i candetect a net connection and then lauch an application. It would also be great if someone could tell me how i can stop the application when the net connection is disconnected.
Plz guys, no lame stuff like using timers!
|

What do you mean by "detecting a net connection"? Are you talking about a connection request coming in from the outside or an outbound connection request? Are you talking about ANY type of connection, like NetWare, NetBIOS, TCP, UDP, ..., or are you just looking at IP traffic only?
There's nothing that will detect all connection traffic and notify you. In order to get something like this to work, you'd probably have to implement a type of firewall to do something like this.

no...what i meant was like ICQ. When ICQ detects an internet connection, it launches the messenger automatically. I want to make something similar. How can i detect an internet connection
|

there are two ways to implement that, the easy way, and the hard way which is i dont know how to do it but i know that u can do it,
ok the easy way is to use i timer that raises an event every 1 seconds for example,
when it fires the event, ping any website do u want, lets say www.codeproject.com, if u got an aknowledgement, then the internet connection is established otherwise, there is no connection
now the HARD way, there is a win32 dll which raises an event whenever the connection is established, u have to import that DLL and hook ur function with it.
actually, it is easier than doing the first way, but if u didnt find the name of that DLL to import it or if u dont have a background about programming win32 API then u have to use the first way

this is it man, the boolean function returns true or false, now all u have to do is to call this function every period of time using a timer, if it returns true, //do something, else //do something else
I'll send u the code by email or ill post it on codeproject.com

I sent the code to ur gmail account

Is there a faster way to give a specific color in a richTextBox?
void makeThisRed(int start, int length)<br />
{<br />
richTextBox1.Select(start,length);<br />
richTextBox1.SelectionColor= Color.Red;<br />
}
|
|
|
|
|
Nope. That's the fastest way to do it...

It is too slow for large richTextBoxes.
Maybe using pointers or something else?
|

It can't be done using pointers...
All RTF formatting is done in-line with the text, kind of like HTML tags. In order for you to change a section of text to a different format, the RTF stream holding all the text and formating information must be rewritten. This means copying everything from the beginning of the RTF stream to the point where you are making your changes, appending the new formatting codes to the copy, append the segment of text you're changing, appending any closing formatting codes that are required, then, finally, appending the remaining original RTF stream.
You can't do it using pointers because you have to rewrite the entire RTF stream anyway so it's in one contiguous stream of data.
It sounds like, because of performance considerations, that an RTF box wasn't a good choice to fulfill your requirements.
