hi All, I am having trouble doing some string manipulation. I get a string with coma delimited. I want remove the first portion of the string.
for example,strMessage = " I, Have, a, string, that, describe, something"
what I want to do is that remove the first coma delimited part of the variable strMessage so it look like this
"Have, a, string, that, describe, something" how do I do this. Any help appreciated.
then I insert the string in my datagridview.
datagridview.Rows.Insert(0,strMessage.Split(','))
I want to keep this style of inserting into dataGridView just want to remove the first portion of the string which is "I".
thanks

string.Split() is the method you want; it has a few overloads, so I refer to its documentation.
BTW: you won't solve problems any faster by putting as much as possible into a single statement. Split things up, and look at the intermediate values while debugging.

this is quite simple for the case you stated. That is just the first comma.
Use IndexOf. Something like:
str.Substring(str.IndexOf(",") + 1).TrimStart();
All the best,

string[] parts = strMessage.Split(",");
for (int i = 0; i < parts.Length; i++)
{
parts[i] = parts[i].Trim();
}
dataGridView.Rows.Insert(0, parts);
But don't you need to ensure that the number of parts matches the number of columns you have in the row?

Hi,
I generate an Xml File with XmlTextwriter.I saved it in a known path (C:\Documents and Settings\My Documents\Visual Studio 2008myprojects\MyFile.xml). I want now to let the user choose where he wants to save his xml File.
How can I import the data from my xml File to copy them in the specified file choosen by the user of my application????
Thank u very much

Good question.
Here is how i did. Suppose user selects the path like this :
Path="C:\MyFile.xml";
Suppose you have an object of xmlDoc containing the xml.
So now we have to create a Filestream for the new path, and then use the StreamWriter class to write the xml to the new path.
FileStream fs=new FileStream(path,FileMode.Create,FileAccess.ReadWrite);
StreamWriter sw=new StreamWriter(fs,Text.Encoding.UTF8);
sw.Write(xmlDoc.OuterXml);
sw.Close();
fs.Close();
Hope it helped!

Hi,
I don't understand what u mean xmldoc.outerxml??? xmldoc is is my xml document?
ty

xmlDoc is an object of XmlDocument. It will contain your MyFile.xml .
XmlDocument xmlDoc=new XmlDocument();
xmlDoc.Load(@"C:\Documents and Settings\My Documents\Visual Studio\MyFile.xml");
and xmlDoc.OuterXml will give you the whole contents of the xml which will be used to write to the new file.

Hi Tarun,
Fine my file is well copied but the problem all tags appear in the same ligne.
How can i get an organized xml file well organized (tags organized)like this:
<GrpHdr>
<MsgId>DOSSIER1</MsgId>
<CreDtTm>2011-03-07T10:39:29</CreDtTm>
<BtchBookg>True</BtchBookg>
<NbOfTxs>2</NbOfTxs>
<CtrlSum>5534,4</CtrlSum>
<Grpg>MIXD</Grpg>
<InitgPty>
<Nm>Dossier1</Nm>
</InitgPty>
</GrpHdr>
As I conclude, it reads them string.
How can I solve that?

hello Turan,
I found a solution. i just add the text.encoding UTF-8 to my code:
this.Response.ContentEncoding = Encoding.GetEncoding ("UTF-8");

Thank u a lot for u help and I am now sssssssssssssssso happy.

If you are already generating the document in your application then why would you need to import it again. Just save it to where the user wants it when you generate it, rather than saving it to your application directory.
If you want to prompt the user for a save location then use the SaveFileDialog[^]
Also, if you want to just copy a file from one location to another then use System.IO.File.Copy()

Hi,
I need to read Remote server Directories through FTP Credentials and bind remote directory
structure to Tree View Control.
Please suggest me better way.
Regards,
Vishnu.

Use FTPWebRequest[^] class. You can get the directory list from here and create your treeview based on that

What is not working... show some code.
If it is not working, then a better way would be to make it work

Hi,
I tried with below code and i'm getting only root directories not sub directories , i need to get sub directories
please suggest me better way.
string ftpServerIP = "75.125.2.193";
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + ftpServerIP + "/");
request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
request.Credentials = new NetworkCredential("barikgr2", "barik122");
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader reader = new StreamReader(responseStream);
string line;
while ((line = reader.ReadLine()) != null)
{
TreeNode node = new TreeNode();
string[] _arv = line.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries);
node.Text = _arv[3];
treeView1.Nodes.Add(node);
}
reader.Close();
response.Close();
Regards,
Vishnu.

Hi,
My code below is in a windows service:
Can you see from the code here, why the backgroundworker_DoWork only gets called once?
I expect it to be called every 200 milliseconds.
There is a timer which gets called every few seconds i.e. OnElapsedTime which does other checks.
But I am trying to have a backgroundworker to run the method GetStatus(); every 200 milliseconds
private static BackgroundWorker _backgroundWorker;
internal static BackgroundWorker BackgroundWorker { get { return _backgroundWorker; } }
private void Initialize()
{
_backgroundWorker = new BackgroundWorker();
_backgroundWorker.WorkerSupportsCancellation = true;
_backgroundWorker.WorkerReportsProgress = true;
_backgroundWorker.DoWork += new DoWorkEventHandler(BackgroundWorker_DoWork);
_backgroundWorker.RunWorkerAsync();
timer.Elapsed += new System.Timers.ElapsedEventHandler(OnElapsedTime);
timer.Enabled = true;
}
private void BackgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
if (_backgroundWorker.CancellationPending)
{
e.Cancel = true;
return;
}
GetStatus();
Thread.Sleep(200);
}
|
|
|
|
|
It only runs once because you are only calling it once. What is you code for your OnElapsedTime event?
Also, why are you using Thread.Sleep in your DoWork event?

I have used sleep because I want to call the Do_Work every 200ms
I am under the impression that the Do_Work event should get called every 200 ms but when debugging it seems that is not the case.
What should I do so that the DO_Work gets called every 200ms in a different thread?
Thanks

Windows isn't a realtime OS, and there won't be a guarantee that your code will spawn a new thread every 200 ms. Depends on how busy the system is - if the threadpool is empty, the BGW will have to wait until another thread is available

The DoWork event is not a loop. You need to call RunWorkerAsync every time you want it to run. This would be best done in your timer event hander and you should remove the thread.sleep call as it is of no benefit to you. There is also little point in having a CancellationPending check as the first thing your DoWork event does - I think you would find it very difficult to see that ever returning true (even if you try to make it happen)
private static BackgroundWorker _backgroundWorker;
internal static BackgroundWorker BackgroundWorker { get { return _backgroundWorker; } }
private void Initialize()
{
_backgroundWorker = new BackgroundWorker();
_backgroundWorker.WorkerSupportsCancellation = true;
_backgroundWorker.WorkerReportsProgress = true;
_backgroundWorker.DoWork += new DoWorkEventHandler(BackgroundWorker_DoWork);
_backgroundWorker.RunWorkerAsync();
timer.Interval = 200;
timer.Elapsed += new System.Timers.ElapsedEventHandler(OnElapsedTime);
timer.Start();
}
private void BackgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
GetStatus();
}
void OnElapsedTime(object sender, System.Timers.ElapsedEventArgs e)
{
if(!_backgroundWorker.IsBusy)
_backgroundWorker.RunWorkerAsync();
}
