Here is the code you asked for...
Dim lstItem As New ListItem
Dim lstItems() As String = Value.Split(",") 'Value = "A,B,C"
For Each lstItem In chklstItem.Items
For I As Int16 = 0 To lstItems.Length - 1
If lstItems(I) = lstItem.Value Then
lstItem.Selected = True
End If
Next
Next
I suggest you to write a property procedure which will GET and SET the values of the CheckBoxList...

John

In your code on the postback
LinkButton lb = (LinkButton)sender;
//From here you can check the ID or command argument or whatever else
I didn't get any requirements for the signature

hi navaneeth,
Thanks for the links.It was really helpful.
Just one question though.
You were saying that i need to maintain a separate database and need to store the brand id rather than the url of the image.
Say if i have 1,00,0000 images and each image has more links ,
how can i maintain the same in SQL?
Also when i retrieve the links for each category, wont the process be slow? Is there any way where i can perform all operations on the backend (maybe a stored procedure) and retrieve only the result as a string in asp.net
Thanks in advance.

Anuradha

This is a common forum. please don't post a question asking to a particular member. May be some other member knows the solution much better than me, but they will hesitate to answer since the question was asked to a particular member. If you have any direct queries you can mail me on navaneethkn@hotmail.com

I am not getting you fully. Why I suggested you to store the ID instead of storing images is to reduce the storage space. If you can't maintain it in such a way what I suggested, you can store the URL.

Yes, process will be slow on searching all these records. So you need to use some alternative solution. How about maintaining another table that won't repeat the image names but will contain all unique image names from the visited history table.
Assume in your visitor table, you are storing the image url. So each time user visits the same page also rows will increase. Searching inside this table would be a costly operation. So you can copy the unique image urls and the total count got for the particular image to the new table. Your new table would contain imageurl and total views.
On your page you can search in this second table which will be less cost. To improve performance use indexing for your table. This can boost your select query performance. Filling second table from history table can be scheduled using SQL Server jobs.

Hey all
Im trying to create a very simple forum where people can basically just post comments.
Ive tried countless tutorials and downloaded many source codes but everything is either:
1: in c# and not VB script
2: In an old VB version and wont convert correctly or...
3: requires a remote connection to a server...this is impossible for me as its a project for university and the network settings dont allow this.
So can anybody PLEASE PLEASE PLEASE point me to a good article or source code download or something..? I need it to not be C#...and like i said...it can be very very simple.
please help

Hi,
sorry, I can't help you with your issue directly.
But have you tried to search guestbook source code?
If you just want users to post comments, a guestbook is
nothing else.

If you need a very simple application where user's can post comments, why don't you create one instead of looking for tutorials.
1 - Which language you are familiar to ?
2 - Which database you are familiar to ?
If it is VB.NET and SQLServer
1 - You need to use SQLConnection. SQLCommand classes
2 - You need a connection string that connects with DB
3 - For inserting into database, Initialize SQLConnection class, Write query to SQlCommand class instance, Use SQLCommand's ExecuteNonQuery() method
4 - For selection either you can use SQLDatareader or a Dataset/Datatabel

Hi,
I'm currently developing a web app which has a number of different roles and forms. I've got a javascript dropdown menu that I'm displaying on each page and depending on role and current form want to show different items. As it stands I'm using a StringBuilder in the Page_Load function to build the script and then add it to a Label:
<br />
if (Page.User.IsInRole("Admin"))<br />
{<br />
menuBuilder.Append("tmenu1.addItem(\"Add New User\", \"Admin/AddUser.aspx\"); ");<br />
menuBuilder.Append("tmenu1.addItem(\"View Admin Tasks\", \"Admin/AdminMaintenance.aspx\");");<br />
...<br />
}<br />
lblMenu.Text = menuBuilder.ToString();<br />
but when I come to view the page the page doesn't appear to load the script. I've checked the page source and the script is definitely in the page and is syntactically the same as I've got it on working pages...
Can anyone shed any light on why this hasn't worked - I'm only assuming it's possible to render script through the Label control into the page??
Cheers
Dave

Did you try RegisterStartupScript or one of the similar Script Emitters?
|
|
|
|
|
I've actually just tried to emit it straight in an 'inline' kind of fashion - is it not possible to do this?
I'll have a good for RegisterStartupScript and see what I can find.
Cheers
Dave

Yes it is, but remember the <script> tags!
You're still better off to use the accepted method of emiting javascript.
