Hi Gandalf,
Thank you for the reply.
Actually it is not mandatory to have login. I thought having logins will be a good idea. Anyway i tell you what I want.
I have already have data in the database which have been stored to some other application. Now I want to do some process on the data. But when i open the application it should load the data aumatically. This I can do for the first time and for a single user. But the requirement is suppose when a user1 uses the application data in the first row has to be loaded and when next user uses it simultaneously second row has to be loaded. like wise if 20 users runs application in the same time or at different time data of 20 rows has to be loaded for the 20 users.

I am trying to display the Image which i have retrieved from Sql .
The problem is i am not able to convert the bytes to image in my webform.
This is my Code.
SqlCommand scmd = new SqlCommand
("select mImage from MyTable where Title='"+ TextBox1.Text + "'", sqlConn);
sqlConn.Open();
Byte[] storedImage = (Byte[])scmd.ExecuteScalar();
Using this i have retrieved the image But how can i display it in the Image control.
Can anybody help me to solve this using C#.

Take a step back and think about how HTML works.
The browser gets the page from the server. The IMG tag in the page points to where the image data is located. The browser makes a seperate request to get the image.
You will need to implement another page (better still an ashx handler), which can write that byte[] out, and set the Response.ContentType to image/jpeg (whatever).
Also please have a google for "SQL Injection" and "Parameterized Queries", because as your code stands now, I can delete anything out your database by typing nasty things into TextBox1...

But in my application i am not going to ask user to type the image names and etc , and i am working in vs.net 2.0 with C#.
Actually my problem is i have to display different images in treenode of a treeview for that i have stored the details and the images in the sql and i have retrieved the image too.
But the thing is i am not able to display the images in my webform.
So is there any way to display the images.

Hi,
With the following code I am getting error that
at this line
int.parse(viewstate["0"]) +=1;
error:-
Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?)
if(!ispostback)
{
viewstate["index"]="0";
}
On Next Button event
if (viewstate["index"].ToString()=="0")
{
//Get question from arraylist with 0 index
int.parse(viewstate["0"]) +=1;
}
else
{
//Get question from arraylist with viewstate index number
string quest=arrlist[int.parse(viewstate["index"])]
//check if question is from last array index then disable next button
if(int.parse(viewstate["index"])==arrlist.count){
//disable next button}else{int.parse(viewstate["0"]) +=1;}
}
On Previous Button event
if (viewstate["index"].ToString()=="0")
{
//Get question from arraylist with 0 index
//disable previous button
int.parse(viewstate["0"]) +=1;
}
else
{
//Get question from arraylist with viewstate index number
string quest=arrlist[int.parse(viewstate["index"])]
int.parse(viewstate["0"]) -=1;
}

HI Knowledge!
Actually I m not getting what exactly ur problem lies.
Is label inside the Grid or Outside?
do ur Source has the Unique Id that u r use to bind the grid?
And yes About the Error :
This Error Generally Arises when There is Unavailability of a Control.

This event doesn't give you any selected row,you have to select row of the gridview as
GridView3.SelectedIndex=e.NewSelectedIndex;
GridView3.datasource=place here datatable
GridView3.databind()
place ur code in the following event. I think your problem will be solved.
protected void GridView3_SelectedIndexChanged(object sender, EventArgs e)
{
string str = GridView3.SelectedRow.Cells[1].Text;
lblMsg.Text = str.ToString();
OR
lblMsg.Text = GridView3.SelectedRow.RowIndex.ToString();
}

Hello Genious...
I have developed folder browser which only displays the folders and not files in browser window..and let users selects folder path.
This user class like Win32SDK and inports dlls like shell32 and shared function
<dllimport("shell32.dll", preservesig:="True," charset:="CharSet.Auto)"> _
Public Shared Function SHBrowseForFolder(ByVal bi As BROWSEINFO) As IntPtr
End Function
and opens the browsing window with
idListPtr = Win32SDK.SHBrowseForFolder(bi).
Now one interesting thing is that this works in my application perfectly.. but when i publish this on local .. its not even open browser window and page opening gets hang...
i think it is may be because security of windows's dll problem..
Any solutions..? please...

Why do you want to display a folder browser dialog from a web application? What purpose does it serve?

Hi Paul..
First of all ,Thanks for replying...
Ok.. now i will tell you why it is needs...
I have requirement like User can be able to select folder path from folder browser.. and then after selecting that, some files will copy from to server to user's selected path(Selected folder)
Eg if user selects desktop then user's selected path is like
C:\Documents and Settings\Administrator\Desktop
and next, some files from my server will copies to users desktop.
Is there any other way to get selected folder path from user's local drive then i will always welcome your any sugestions...
Thanks..

You can't do this. The browser can't access local resources on the client machine for obvious security reasons. Otherwise, websites could do malicious things with your user's file system. You have to adopt a different mindset when working with web applications. Some of the things you take for granted in Windows applications simply are not possible.
The best thing you can do is to provide the facility to download a file or files. You could consider packaging a set of files up into a ZIP archive and then providing the user with the facility to download it.

Is your application in asp.net? if yes then why you are not using classes in system.io namespace to browse folders.
