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.

I've added a scalar property to an entity and now ASP.NET Dynamic Data scaffolding throws this error:

The number of members in the conceptual type 'TrainingModel.Users' does not match with the number of members on the object side type 'TrainingModel.Users'. Make sure the number of members are the same.

string.Split - not all characters allowed as separator



I am working on a site where I use the Split function on a string.

To make sure I used a separator character that I do not use anywhere in the data I selected the character '£'.

This worked fine in Firefox and Safari, but in IE8 I get an 'Index out of range' error, so apparently the '£' character is not handled correctly.

I changed the separator to ';', and then it works fine.



Child nodes not allowed.


Hi everyone.

I'm positive that, by now, a lot of people have run into this problem but even with all the forum posts with great answers, I still can't seem to get to the bottom of it. Here are some specs:

  • Windows Server 2008
  • Visual Studio 2008 x86

So here's the issue:

I have VS2008 installed on the server listed above. This is our development server and everything is created and tested here. I have created an asp.net application, tested it on the dev. environment and everything works great. When I try to migrate this application up to our Quality Assurance environment (which is Windows Server 2003), I get the error in the subject title.

I've read many things that can be the cause of this and I'm positive that I know 2 ways of fixing it. One is from this post: Simple web site problem on Vista, related to <providerOption>, and the other is making sure 3.5 framework is at least installed on the server in question. There are 2 reasons why I'm unable to use these 2 methods:

  • The patches from DVD that I'm supposed to install won't let me install them. Upon double clicking I recieve a message saying the "Update is not applicable to your computer"
  • I don't have permission to install 3.5 frame

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.

Delete spaces created by combining 2 fields


Howdy, this is kind of a continuation of an answer I got from this thread:  http://forums.asp.net/t/1592766.aspx

My users will enter a city/station where an incident occured, and the date.  The trigger below does work, but it will occasionally put spaces between the citystation and the date.  I think this happens when the citystaion name is not very long, but not sure.

(ex: city____08242010)

How can I make sure that if the incidentid is going to have spaces, that sql deletes those spaces?  I need the id to be space free.

SharePoint Workflow E-mail Hyperlink has the Spaces Between Two Words Are Removed

I have a very simple Workflow, that includes href link to Infopath form.
If the form name includes spaces, the URL redirects to a The Form has been Closed message, indicating that it cant find that form.
In our scenario, the file name of the document/form in SharePoint when saved is called "Travel Request - <submit date>"  as noted with spaces.
The Hyperlink URL in the email generated by the workflow appears to encode all values in the name after the first two words (after Request).  See below.  after the word Request the spaces are encoded properly.     its replacing the first space with it appears %0d%0a (CR LF)
The URL below is what is displayed when right clicking, and selecting Edit Hyperlink in the email

I can reproduce this in development and production.  Any ideas on how this can be resolved?

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.
