Yes, but that is true for any value that you get from the request.

I am an application programmer working in a private firm.I am now working on a project.
The prject is related to survey.So for this we have to genarate a word reaport after completing every survey.For this we run a vbscript file with scheduler.But the problem is
that it takes 45 minutes time to genarate every reaport.But the critical problem is that
when 9 user are put there survey at the same time then they have to wait for 9-15 hours.
So please give me the solution how can I speed up the time for reaport genaration using
.net.

Hi to All,
Anybody Tell me what is the Different between .NET 2005 AND .NET 2003.
Mohan Balal
|
|
|
|
|
there is no .net2003/5, only .net 2.0/3.0 which is the sdk for u to write applications.
Maybe u mean visual studio .net/ visual studio 2005, the latter is the later version embedded .net sdk 2.0
|
|
|
|
|
Ask our friend google!
You would find enough differences and new features in 2005
Gautham
|
|
|
|
|
Try to write a subject that better describes your question.
Visual Studio 2003 targets .NET framework 1.1, and Visual Studio 2005 targets .NET framework 2.0. That's the most distinguishing difference, other than that there are just a lot of small features added to VS 2005. As gauthee said, you can search the web to find information about these, that's the best way of finding answers to general questions like this. A forum like this is better suited for answering more specific questions.

YOu got to convert the image right! when you say select image it would not simply return imageinstead it returns binary data
Gautham
|
|
|
|
|
i know that is return binary data.
and i know how to convert binary data to image.
but i dont know how to put converted image to page on the fly without saving images in any folder?

You can use a MemoryStream:
<br />
private static int chunkSize = 10000;<br />
private void writeData(object yourImageBinaryData){<br />
MemoryStream ms = null;<br />
int dataLeft = 0;<br />
<br />
try<br />
{<br />
dataLeft = ((byte[])yourImageBinaryData).Length;<br />
ms = new MemoryStream((byte[])yourImageBinaryData);<br />
<br />
while(dataLeft > 0 && Response.IsClientConnected)<br />
{ <br />
byte[] currentChunk = new byte[chunkSize];<br />
int currentChunkSize = ms.Read(currentChunk, 0, chunkSize);<br />
<br />
Response.BinaryWrite(currentChunk);<br />
<br />
dataLeft -= currentChunkSize;<br />
currentChunk = null;<br />
}<br />
}<br />
catch(Exception e){<br />
throw new Exception("writeData failed. " + e.Message);<br />
}finally{<br />
if (ms != null)ms.Close();<br />
ms = null;<br />
}<br />
}<br />
Hope it helps

You could putt each image in DataGrid, repeater, listcontrol.
You could also create your own class that contains the image from the database.
Something like this:
First create an empty .aspx page
<%@ Page language="c#" Codebehind="MyImageClass.aspx.cs" AutoEventWireup="false" Inherits="My.Publishing.MyImageClass" %><br />
The code behinde:
using System;<br />
using System.IO;<br />
using System.Drawing.Imaging;<br />
using Millum.Procurement.Imaging;<br />
using System.Runtime.Serialization;<br />
using System.Runtime.Serialization.Formatters.Binary;<br />
using System.Web;<br />
using System.Web.Caching;<br />
using System.Collections;<br />
namespace My.Publishing{<br />
public class MyImageClass : System.Web.UI.Page{<br />
private static int chunkSize = 10000;<br />
override protected void OnInit(EventArgs e){<br />
InitializeComponent();<br />
base.OnInit(e);<br />
}<br />
private void InitializeComponent(){<br />
uploadData();<br />
}<br />
private void uploadData(){<br />
string strID = null;<br />
<br />
strID = (Request.QueryString["attID"] != null)?Request.QueryString["attID"]:(Request.Form["attID"] != null)?Request.Form["attID"]:null;<br />
<br />
byte[] byteImg1 = getImage("select picture from database where id=" + strID );<br />
<br />
writeData(byteImg1);<br />
}<br />
<br />
<br />
private void writeData(byte[] yourImageBinaryData){<br />
MemoryStream ms = null;<br />
int dataLeft = 0;<br />
<br />
try<br />
{<br />
dataLeft = yourImageBinaryData.Length;<br />
ms = new MemoryStream(yourImageBinaryData);<br />
<br />
while(dataLeft > 0 && Response.IsClientConnected)<br />
{ <br />
byte[] currentChunk = new byte[chunkSize];<br />
int currentChunkSize = ms.Read(currentChunk, 0, chunkSize);<br />
<br />
Response.BinaryWrite(currentChunk);<br />
<br />
dataLeft -= currentChunkSize;<br />
currentChunk = null;<br />
}<br />
}<br />
catch(Exception e){<br />
throw new Exception("writeData failed. " + e.Message);<br />
}finally{<br />
if (ms != null)ms.Close();<br />
ms = null;<br />
}<br />
}<br />
<br />
Now the page where the images is viewed, this is an example with
a DataGrid, where the image is displaide in a imagebutton:
<br />
asp:datagrid id="dgImages" runat="server" CssClass="grid" AutoGenerateColumns="False" GridLines="None"<br />
ShowFooter="True"><br />
SelectedItemStyle Font-Bold="True" CssClass="grid_itemSelected"></SelectedItemStyle><br />
EditItemStyle CssClass="grid_itemEdit"></EditItemStyle><br />
AlternatingItemStyle CssClass="grid_itemAlternating"></AlternatingItemStyle><br />
ItemStyle CssClass="grid_item"></ItemStyle><br />
HeaderStyle Font-Bold="True" CssClass="grid_header"></HeaderStyle><br />
FooterStyle CssClass="grid_footer"></FooterStyle><br />
Columns> <br />
asp:TemplateColumn ItemStyle-HorizontalAlign="Center" ItemStyle-VerticalAlign="Top"><br />
ItemTemplate><br />
asp:ImageButton ID="imgFT" runat="server" CommandArgument='<%#DataBinder.Eval(Container.DataItem, "lngImageID").ToString()%>' AlternateText="Show/Download$" CausesValidation="True"><br />
/asp:ImageButton><br />
/ItemTemplate><br />
/asp:TemplateColumn><br />
/Columns><br />
/asp:datagrid><br />
Then you need a ItemCreated method for the datagrid:
<br />
#region Web Form Designer generated code<br />
override protected void OnInit(EventArgs e)<br />
{<br />
InitializeComponent();<br />
base.OnInit(e);<br />
}<br />
<br />
private void InitializeComponent()<br />
{<br />
this.dgImages.ItemCreated += new System.Web.UI.WebControls.DataGridItemEventHandler(this.dgImages_ItemCreated);<br />
this.Load += new System.EventHandler(this.Page_Load);<br />
<br />
}<br />
#endregion<br />
<br />
private void dgImages_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)<br />
{ <br />
try <br />
{<br />
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) <br />
{<br />
DataRowView drv = (DataRowView) e.Item.DataItem; System.Web.UI.WebControls.ImageButton img = new ImageButton();<br />
img = (System.Web.UI.WebControls.ImageButton)e.Item.FindControl("imgFT");<br />
img.Click += new System.Web.UI.ImageClickEventHandler(btnImage_Click); <br />
if(drv != null)<br />
{<br />
int lngImageID = Convert.ToInt32(drv.Row["ID"]);<br />
img.BackColor = Color.Transparent;<br />
img.BorderStyle = BorderStyle.None;<br />
<br />
img.ImageUrl = "../MyImageClass.aspx"?attID=" + lngImageID.ToString();<br />
}<br />
catch (Exception err) <br />
{<br />
}<br />
}<br />
Ofcource you now have to get all the imageIDs from the user:
<br />
DataVies dvAllImageIDs = getAllImageIDsForTheUser();<br />
dgImages.DataSource = dvAllImageIDs;<br />
dgImages.DataBind();<br />
This code is bits and pizes of a hole bigger control, so theres
probably some errors, but you get the point.
Hope it helps

}
---------------------------------------
Here I have just one table.
Category_Master
And Column are :
Category_id
Category_Name
Parent_Category_ID
Join condion is self join.
You can change query and join condtion as per your data.

All the state name values are "select". So the code may be checking if the value is not "select" accept the value. Please try it out with this logic
