VB - Random Number for Multiple Labels



Not sure if I'm approaching this correctly but this is what I've got and what I'm trying to do

I have a table with 10 Labels in it (Labels Id A1 thru A10)

I'm trying to have each label assigned a random number using 0-9

Need to have each labels number value different from the other

Code Below:


A1.Text = Int(Rnd() * 10)

A2.Text = Int(Rnd() * 10)

A3.Text = Int(Rnd() * 10)

A4.Text = Int(Rnd() * 10)

A5.Text = Int(Rnd() * 10)

A6.Text = Int(Rnd() * 10)

A7.Text = Int(Rnd() * 10)

A8.Text = Int(Rnd() * 10)

A9.Text = Int(Rnd() * 10)

A10.Text = Int(Rnd() * 10)

Thanks in Advance



How to generate a random number sequence that is non-repeating in visual basic .net ?


I am writing a matching program, and need 24 objects to randomly appear, each twice, across 48 spaces. I figured the best way for me to do this would be to assign the positions a number 1 through 48. but the problem is I can't find a way to generate a random number sequence in visual basic 9 .net

I found many examples in visual basic .net but the conversion doesn't work. If not some code, many some example programs that either use a random number sequence or randomly sets the position of objects.

dynamically adding sql server columns based on number of files in fileuploader


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.


I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!


Dim objConn As New SqlConnection("Server=<servername>;uid=<userid>;pwd=<password>;database=master")


Embeb a variable number of videos


I need to provide some alternate content for my non-Flash users.

I have a directory of video files that is scanned using the DirectoryInfo() function, and I want to use the results to embed all files ending in ".mov" in QuickTime players on a web form.

How would you approach this? Right now I am using the count on the array of videos to determine how many times to repeat the embed code.  But this seems inelegant.

Is there a way to have a single QuickTime player.ascx control that gets duplicated according to the number of videos available for display?

Article commenting by line number


I'm wondering what's the best way to approach an online article system that allows users to comment by clicking on the line they are commenting about? Essentially the same way Adobe Acrobat works with comments where you can click anywhere and the text is saved for that location.

I'm assuming a mix of jQuery would be the crux of the interface. The system would need to save comments so that when another user logs in, they will also see the other comments but they can´t edit them - only add their own.

Any suggestions would be great.

How to show 0 as first number in column


Hi guys. I have two little problem.

I have database with one table and it has 4 rows.

1. I want to show a zero in front of all number. Actually i added but it doesn't show.

2. If i don't put any value in column is it possible to have minus for example instead of 0?




I post it like that because i can't see how to post pics directly.

P.S. The columns with numbers have checked "allow nulls".

I draw in paint so it's not so good but i think it's understandable.

10x in advance.

IIS - sharepoint/default website port number confusion



I have MOSS 2007 installed with IIS V7.

My default web site port is 80. When I created a new web application for my main sharepoint portal I also set it to 80. So obviously now the default web site port shows as stopped in IIS and it won't start.

What are the best practices. Should I change the port number for my portal to something else? I mean is it even a good idea to have sharepoint on port 80? If so, how do I go about changing the port number for my portal site?

any help appreciated.
