I want to write code on textchanged event for rich text box, such that user can specify the no. of chracters in a single line, and according to that the word wraps.
Plz help me

If user inputs some lines and come back to previous line, like editing the text, then problem occurs like its overwriting.
Ex line:"1. This Code is giving me much problem as i m fresher."
like this user enter 3-4 lines or paragraph?
Now if user comes back to 1 line and edit, its messed up like:
"1. This code hai s giving me much problem as i m fresher."
Here i try to enter have after code.
Plz help.
private void txtBody_TextChanged(object sender, eventArgs e)
{
if(tbWordwrap.Pushed)
{
string[] tempArray = new string(txtBody.Lines.length);
tempArray = txtBody.Lines;
int Prevsel = txtBody.SelectionStart;
string Op = "";
int maxLength = cINI.dbUtils.Pref.DefaultEditorWidth;
bool change= false;
for(int cou = 0; cou < tempArray.Length ; cou++)
{
if (tempArray[cou].length > maxLength)
{
string words = tempArray[cou].split(' ');
int currentLine Length = 0;
string currentLine = "";
foreach(string currentWords in words)
{
if(currentWord.Length > 0)
{
if(currentword.Length >= maxLength)
{
Op += currentword.Insert(maxLength, "\r\n");
break;
}
if(currentLineLength + currentword.Length + 1 < maxLength)
{
currentLine += currentword + " ";
currentLineLength += currentword.Length +1;
}
else
{
Op +=currentLine.Insert(currentLineLength, "\r\n");
currentLine = currentWord;
currentLineLength = currentWord.Length;
}
}
}
if(currentLine !="")
Op += currentLine;
PrevSel++;
change = true;
}
else
{
Op += tempArray[cou] + "\r\n";
}
if(change)
{
txtBody.Text = Op;
txtBody.SelectionStart = prevSel;
}
}
}
The above code is for text_change event of RichText Box in C# vs.net 2003.

Hi,
1.
what is this? the code does not compile at all, it is full of mistakes.
C# is case-sensitive, what are currentWords, currentWord and currentword ??
.NET methods start with an upper-case, there is no string.split, no string.length.
2.
the algorithm is flawed. If you insert in the middle of a line, the last word
would get moved to the next line; if you keep inserting, another word would
get moved to the next line; in the end all the words are on separate lines.
You can't do proper word wrapping without recombining words to lines.
But then you also need a way to indicate the start a new paragraph.
3.
A TextBox has built-in support for word wrapping; I guess it will function a lot
better than anything you will come up with any time soon.
Goodbye.

The thing is its a very small firm in which i m working, & have no senior to help. on my own i tried every possible way,
All is fine(Acc. to me), only the editing or modifying the text creates problem.
if user enter 3-4 lines:
"This is trial message plz ignore.
This is trial message plz ignore.
This is trial message plz ignore.
This is trial message plz ignore."
and now when user comes back to first line and enter some data in between, then the problem starts,
plz sir
private void txtBody_TextChanged(object sender, System.EventArgs e)
{
#region "wrap"
string[] tempArray = new string [txtBody.Lines.Length];
tempArray = txtBody.Lines;
int PrevSel = txtBody.SelectionStart;
string Op = "";
int maxLength = Convert.ToInt32(textBox1.Text);
bool change= false;
for(int cou = 0; cou < tempArray.Length ; cou++)
{
if (tempArray[cou].Length > maxLength)
{
string[] words = tempArray[cou].Split(' ');
int currentLineLength = 0;
string currentLine = "";
foreach(string currentWord in words)
{
if(currentWord.Length >= 0)
{
if(currentWord.Length >= maxLength)
{
Op += currentWord.Insert(maxLength, "\r\n");
break;
}
if(currentLineLength + currentWord.Length + 1 < maxLength)
{
currentLine += currentWord + " ";
currentLineLength += currentWord.Length +1;
}
else
{
Op +=currentLine.Insert(currentLineLength, "\r\n");
currentLine = currentWord + " ";
currentLineLength = currentWord.Length;
}
}
}

else
{
Op += tempArray[cou] + "\r\n";
}
if(change)
{
txtBody.Text = Op;
txtBody.SelectionStart = PrevSel;

And I need a hand in this
tree_Level.Nodes.Clear();
for (int x = 0; x < dataSet1.COMMS.Rows.Count; x++)
{
tree_Level.Nodes.Add(dataSet1.COMMS.Rows[x]["COMM_NAME"].ToString() + "_" + dataSet1.COMMS.Rows[x]["COMM_ID"].ToString(), dataSet1.COMMS.Rows[x]["COMM_NAME"].ToString(), 0, 0);
for (int y = 0; y < dataSet1.UZL.Rows.Count; y++)
{
if (dataSet1.UZL.Rows[y]["UZ_COMM_ID"].ToString() == dataSet1.COMMS.Rows[x]["COMM_ID"].ToString())
{
tree_Level.Nodes[x].Nodes.Add(dataSet1.UZL.Rows[y]["UZ_NAME"].ToString() + "_" + dataSet1.UZL.Rows[y]["UZ_ID"].ToString(), dataSet1.UZL.Rows[y]["UZ_NAME"].ToString(), 1, 1);
for (int z = 0; z < dataSet1.VILS.Rows.Count; z++)
{
if (dataSet1.VILS.Rows[z]["VIL_UZ_ID"].ToString() == dataSet1.UZL.Rows[y]["UZ_ID"].ToString())
tree_Level.Nodes[x].Nodes[0].Nodes.Add(dataSet1.VILS.Rows[z]["VIL_NAME"].ToString() + "_" + dataSet1.VILS.Rows[z]["VIL_ID"].ToString(), dataSet1.VILS.Rows[z]["VIL_NAME"].ToString(), 2, 2);
}
}
}
}
The last level in the loop is not doing fine (it puts all the second level subordinates under one node that is the first node in level two
ps. I know it's a mess but please just focus on the two inner nested loops.

It's failing because you are assigning your new node at Nodes[x].Nodes[0] which will always be the same node under [x]. To get round this, change it to Nodes[x].Node[y], or better still maintain this via explicit TreeNodes.

Is Crystal Report tools is not come with .Net Framework at the time of installation?

Try that again without the use of double-negatives.
Does Crystal Reports come with the .NET Framework?
or
Is this right? Crystal Reports does not come with the .NET framework?
You see - 1 negative per question.

Hey,
This XML stuff drives me crazy (almost)
I have a string with the following XML
<object class="user" name="admin2@test.dk" xmlns="">
<property name="cn">
<value>admin2@test.dk</value>
</property>
<property name="sn">
<value>efternavn</value>
</property>
<property name="description">
<value>some desc</value>
</property>
<property name="telephoneNumber">
<value>789</value>
</property>
<property name="givenName">
<value>fornavn</value>
</property>
</object>
How do I parse that string and get the value for an element like "telephoneNumber"?
Thanks in advance

You can do that First Convert that String into Stream then put that Stream as parameter to XmlTextReader constructor and read that
Thanks and Regards

First thing first, load it into a XMLDocument
XmlDocument xmlDoc = new XmlDocument();<br />
xmlDoc.LoadXml(yourStringOfXmlData);
Then, use XPath to find the right node
XmlNode node = xmlDoc.DocumentElement.SelectSingleNode("property[@name='telephoneNumber']/value");<br />
if(node != null)<br />
Console.WriteLine(node.Value);<br />
code typed without testing.
