How can we implement CallOuts to a text document in web application
|
|
|
|
|
what is the diffrence between string and string builder
|
|

Hi
I think you must read MSDN - StringBuilder Class
This class represents a string-like object whose value is a mutable sequence of characters. The value is said to be mutable because it can be modified once it has been created by appending, removing, replacing, or inserting characters. For comparison, see the String class.
Most of the methods that modify an instance of this class return a reference to that same instance. Since a reference to the instance is returned, you can call a method or property on the reference. This can be convenient if you want to write a single statement that chains successive operations one after another.
The capacity of a StringBuilder is the maximum number of characters the instance can store at any given time, and is greater than or equal to the length of the string representation of the value of the instance. The capacity can be increased or decreased with the Capacity property or EnsureCapacity method, but it cannot be less than the value of the Length property.
Implementation-specific default values are used if no capacity or maximum capacity is specified when an instance of StringBuilder is initialized.
Notes to Implementers: The default capacity for this implementation is 16, and the default maximum capacity is Int32.MaxValue.
A StringBuilder can allocate more memory as needed to store characters when the value of an instance is enlarged, and the capacity is adjusted accordingly. The amount of memory allocated is implementation-specific, and ArgumentOutOfRangeException is thrown if the amount of memory required is greater than the maximum capacity.
For example, the Append, AppendFormat, EnsureCapacity, Insert, and Replace methods can enlarge the value of an instance.
The individual characters in the value of a StringBuilder can be accessed with the Chars property. Index positions start from zero.

The short answer is that you use String Builder when you are doing operations on a string, such as concatenation. It's optimized for those operations more than strings.

my code is as under Here I have table called folder and in this table unique key is ID and parent key is ParentFolderID which reference to Id of the same table so if there are sub folders then ParentFolderId will be parent Folder's ID. So if there is table which is root level then its ParentFolderID will be reference to itself.
Try
RootFolderStr = "Select Name from Folder where ID=ParentFolderID"
dr = temp.ExecuteDataReader(RootFolderStr)
While dr.Read
Root = dr("Name")
tNode.Text = Root
Tree1.Nodes.Add(tNode)
End While
Catch ex As Exception
MsgBox(ex.Message)
Finally
dr.Close()
End Try

"Index must be within the bounds of the List.Parameter name: index"
So please help if any one knows the answer.
Thanks in advance

Include Microsoft.Web.UI.WebControls.dll in your project.
For runtime addition of nodes for TreeView control do following steps
//On aspx page register TreeView as
<%@ Page language="c#" Codebehind="TreeControl.aspx.cs" AutoEventWireup="false" Inherits="UserControlApplication.TreeControl" %>
//Treeview Control
//Add the root node for User Control Tree1 in .cs file
TreeNode tNode = new TreeNode();
tNode.Text="Root";
tree1.Nodes.Add(tNode);
//Add Child Node to root node tNode
TreeNode tChileNode1 = new TreeNode();
tChileNode1.Text = str;//This string is the information retrieved form database
tNode.Nodes.Add(tChileNode1);

Try this -
Define your chile node inside while loop and fill it and after it add to root node.

I need to add a "ENTER" whitespace into string, so when i display the string into control, the string will be continue display on next row.
How to add this "ENTER" ?
for example;
dim str as string = "A ENTER B"
so the output will be :
A
B
Best regards,
Chee ken

Use Environmend.NewLine:
Dim str As String = "A" + Environment.NewLine + "B"
Then of course it depends on if the control handles line breaks in the text or not.
---
b { font-weight: normal; }
|
|
|
|
|
Dim str As String = "A" + <-br-> + "B"
plz remove "-" side of the "-br-"
hi
hope can work.
