Iam facing a lot of problem to parse this file into XML file.

I am sure, everybody will have problems reading this file. BTW is this a single record or multiple records ? Also my understanding about CSV (Comma Seperated Values) is comma seperated fields and new line seperated records. Is the file in same format ? Or even this file can be called as CSV ?

I do not think anybody can help you with this. I suggest you to separate the file into individual records and fileds first. Yuo may use the String.Split() method for that purpose. Then you must find out what structure the file has. You should create the XML datatype and finally you can parse the data and convert it to XML. Don't expect us to do this for you.

one way to do it
u should write code in every control's MouseEnter event.

Oh, you're using VS2003. Then WriteAllText is not an option.

mr jets wrote:

You keep posting this, there's no such thing as StreamWritet, is this really not a typo ?

System.IO.FileStream fs = new System.IO.FileStream("c:\\testing.txt", System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Write, System.IO.FileShare.ReadWrite);

// create a stream writer
System.IO.StreamWriter sw = new System.IO.StreamWriter(fs, System.Text.Encoding.ASCII);

// write to file (buffer), where textbox1 is your text box
sw.Write("text");

// flush buffer (so the text really goes into the file)
sw.Flush();

// close stream writer and file
sw.Close();
fs.Close();

Perhaps the defaults for the params you're not passing in, are not the ones you need ?

i reaally appreciat ur time bro..okie ur code creating atext in c drive but it doesnt save the values of (x,y,..) remember bro my program like Paint ..so when i open the text it doesnt display my drawings (line,polygon,..)
thats my open code :

String fileName ; // name of file to containing data
// exit event handler if user clicked "cancel"
if (result == DialogResult.Cancel)
return;
// get specified file name
fileName= fileChooser.FileName;
//show error if user specified invalid file
if (fileName=="" || fileName==null)
MessageBox.Show("Invalid File Name ","Error",MessageBoxButtons.OK,MessageBoxIcon.Error);
else
//creat Filestream to obtain read access to file
input = new FileStream(fileName,FileMode.Open,FileAccess.Read);

}

I'm not sure that I understand. I see you opening a file stream, but I don't see you reading anything, nor does the fact that you read the text have anything to do with seeing polygons ( there's a step in the middle where the text is intepreted to give you the data to show that )

Re: postback or DoPostback

26-Apr-07 22:08

I have no idea. Reading a text file is NOT going to do anything more than put some text into a piece of memory. For that to turn into ellipses, or whatever, you need to write some code that does that.

So, it depends. what is in this text file ? How did it get there ? How did you expect this text to become something on your screen ?

I am attempting to programmatically call a hyperlink in a webbrowser control. The links are simply numbers 123456789… each corresponding to a new page to navigate to. The reference to each page is of the form “” where each page corresponds to a parameter as follows:

Page 1 is ---- javascript:__doPostBack('grdjo$_ctl1$_ctl1','')
Page 2 is ---- javascript:__doPostBack('grdjo$_ctl1$_ctl2','')
Page 3 is ---- javascript:__doPostBack('grdjo$_ctl1$_ctl3','')
…

The page uses the Javascript postback function below:

I am able to load the page using HttpWebRequest & HttpWebREsponse and have passed in the parameter to load the page as follows.

byte[] buffer = Encoding.ASCII.GetBytes("grdjo$_ctl1$_ctl6");

yet the page will not load the correct content, it keeps loading the first page of links. I know I am doing something wrong. Any ideas?

Thanks

Karl

Here is the code that does the postback...

string strParm1Val = "grdjo$_ctl1$_ctl6";
string strParm2Val = "";
string strPage = "http://somepage.com/frmjosearchp.aspx?GUID=www&keyword=&FOFID=400194";

string strData = "";

frd.Controls["resultsRichTextBox"].Text = "LOADING PAGE....";

byte[] buffer = Encoding.ASCII.GetBytes(strParm1Val + "&" + strParm2Val);
//Init
HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create(strPage);

//Our method is post, otherwise the buffer (postvars) would be useless
WebReq.Method = "POST";

//We use form contentType, for the postvars.
WebReq.ContentType = "application/x-www-form-urlencoded";

//The length of the buffer (postvars) is used as contentlength.
WebReq.ContentLength = buffer.Length;

//We open a stream for writing the postvars
Stream PostData = WebReq.GetRequestStream();

//Now we write, and afterwards, we close. Closing is always important!
PostData.Write(buffer, 0, buffer.Length);
PostData.Close();

//Get the response handle, we have no true response yet!
HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();

//Let's show some information about the response
Console.WriteLine(WebResp.StatusCode);
Console.WriteLine(WebResp.Server);

//Now, we read the response (the string), and output it.
Stream Answer = WebResp.GetResponseStream();
StreamReader _Answer = new StreamReader(Answer);
strData = _Answer.ReadToEnd();
_Answer.Dispose();

//Console.WriteLine(_Answer.ReadToEnd());

//update controls on other forms
frd.Controls["ResultstextBox"].Text = strData;
frd.Controls["resultsRichTextBox"].Text = strData;
Uri siteUri = new Uri((string)strPage);
webBrowser1.Url = siteUri;

I recommend not saying things like this when asking for free advice.

System.IO.File.WriteAllLines or System.IO.File.WriteAllText are the easiest way to create a text file.

Having said that, your code compiles just fine here. What line gives the error ?

ok frist of all ..iam sorry bout my behavior but save & open its apart of very very huge program ..the dead line after 5 hours..so thank god i didnt kill my some one ..
ok the error at ...:
StreamWriter streamWriter=new StreamWriter(outStream);
plzz if u know more simple code..i will invite u to cinema..kidding!! OMG | :OMG:

Christian Graus25-Apr-07 15:14

Building the string and using WriteAllText is definately simpler.

I don't get the error, because, like I said, it compiled fine here.

mr jets25-Apr-07 15:19

25-Apr-07 15:19

and using WriteAllText is definately simpler..iam not familiar with that..how will be the code look like..?! D'Oh! | :doh:
