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!!!

Code Name WinFS: Revolutionary File Storage System Lets Users Search and Manage Files Based on Conte


One of the monumental problems organizations face today is aggregating information that's stored in disparate formats. Knowledge workers have long wanted to be able to search for content independent of format. The next version of the Windows operating system, code-named "Longhorn," boasts a new storage subsystem that makes that task easier. That subsystem, code-named "WinFS," allows the user to perform searches based on the metadata of the stored item, regardless of what type of file it is or which application created it. This article covers the basic architecture of WinFS and explains how to use the WinFS managed API.

Updating Config Files in Sharepoint Farm

I am trying to update config files web.comnfig in the Virtual Directory of my server so that users are allowed to upload more that 50 MB of files in my IIS 7 server. Everytime i do the update it works fine but after few days when there are few changes then it removes the added elements itself and restore in the Original Stage. I used to edit my config files manually. I found a way of creating a config files and saving it to the Config Directory under 12 Hive in Server. Like the Content will be similar as follows <actions>    <add path="configuration/SharePoint/SafeControls">       <SafeControl          Assembly="System.Web, Version=1.0.5000.0, Culture=neutral,             PublicKeyToken=b03f5f7f11d50a3a"          Namespace="System.Web.UI.WebControls"          TypeName="*"          Safe="True"/>    </add>   </actions> I have to add following line <system.webServer>     <security>       <requestFiltering>         <requestLimits maxAllowedCon

display files to download based on who is logged in

I have an asp.net web app. I have secure parts to the website and currently I have it setup so that people can login with their domain accounts. The are three secure sections to the site, all of which require files of interest be displayed to the user so they can download them.Okay so this is how I see it working, people come to the home page and select on one of the three options. At this point they are prompted for there domain password then they are navigated to the secure page and a bit of code populates the page with file downloads based on who they are logged in as.The files themselves will be uploaded to the website and kept in folders named after the username. so for instance the user edwardh would be displayed the files in the folder /downloads/edwardh.I'm not sure where to start with this, any direction?

SharePoint Farm - Claims Based Authentication Problems


Hello guys,

I have a SharePoint farm with 2 WFE servers(SH01 and SH02) and 1 Application server(SH03) where there's the Central Admin. When I create a WebApplication with Windows Authentication I can access it normally in both address http://SH01:10000 and http://SH02:10000. When I create a WebApplication with Claims Based Authentication enabling FBA when I try to access it with the address above occurs an error:

The WebApplication at http://SH01:10000/  could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application.

I have noticed that the difference between authentication is that FBA redirect to "_login/" when I can choose what type of authentication I want to login(In this case Windows or Forms).

Are there some extra configuration that I have to do to solve this problem?

I would like to update my database based upon files that are found in a certain directory.


I'm having an incredibly hard time with this, I'm really new to it.  I'm creating a website for free web graphics and I would like to add data to my database whenever more files are added to my server.  I've found a way to list all the files in the directory:

<script language="C#" Runat="server">
        // declare the page level variable for the path
        String FilePath;
        protected void Page_Load(object sender, EventArgs e)
            FilePath = Server.MapPath("~/thumbs");            
            GetFiles();  //call the GetFiles method
            lblHeader.Text = "Files in " + FilePath;
        private void GetFiles()
            //Create the DataTable, with columns in which to add the file list
            DataTable dt=new DataTable();
            dt.Columns.Add("Thumb Exists?", typeof(System.String));
            DataRow dr=null;
            DirectoryInfo dir=new DirectoryInfo(FilePath);

            // Iterate through the datatable,
            // adding file to a new row, along with the  filesize to each row

Clean Web.Config Files (VS 2010 and .NET 4.0 Series)

.NET 4 includes a new version of the CLR, and a new .NET 4 specific machine.config file (which is installed side-by-side with the one used by .NET 2, .NET 3 and .NET 3.5).

The new .NET 4 machine.config file now automatically registers all of the ASP.NET tag sections, handlers and modules that we've added over the years, including the functionality for:

.ASP.NET Dynamic Data
.ASP.NET Routing (which can now be used for both ASP.NET WebForms and ASP.NET MVC)
.ASP.NET Chart Control (which now ships built-into ASP.NET V4)
What this means is that when you create a new "Empty ASP.NET application" project in VS 2010, you'll find that the new default application-level web.config file is now clean and simple:

5 GridView Themes Based on Google's Personalized Homepage (igoogle)

One of the silly features I have found that I like about igoogle is how the pages color palette changes depending upon the time of day. So as the day progresses from morning to afternoon to evening the colors on the page change as well. Like I said, I know this is a silly feature, but I like it. And I have asked around a little bit and seems like other people like it to. To get a better idea of how the colors change, here are the background images from a few of the HTML elements.

How to transfer files between computer and mobile device using bluetooth

What is Bluetooth? How can I have it on my computer?

Bluetooth wireless technology is a communication technology that allows two devices to communicate wirelessly. Most of the notebooks are nowadays equipped with bluetooth. For those notebooks or computers that don't, you can use a bluetooth dongle to add the functionality and it just costs you around $5. Although higher price range bluetooth dongles are available but it makes no sense of buying them if you just plan to connect your mobile device to the computer. Look for one that has Bluetooth v2.0 + EDR (Enhance Data Rate) supporting speeds of upto 3Mbps and with Vista support. You can easily have one of that kind in just $5.

Setting up bluetooth to work on your computer

Just Insert the bluetooth dongle in the USB.
It should get detected by your Operating System and should be ready to use. In case it is just detected as a new hardware, you need to install drivers for it that came with your bluetooth dongle (You can try Google to find the drivers).
Once drivers are installed, a bluetooth notification icon will appear in your system tray.
Right Click on it to access Settings (This may vary with your bluetooth dongle).
Make sure you have turned Discovery On (It allow others to see your computer).
Switch On the bluetooth on the mobile device.

Unique content within master page based on conditions met


 Hi all-

I would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx).  The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. 

However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML,  Divs and databound gridview content.  The HTML content will be stored in the database.

Can someone point me in the right direction for best practices on how to accomplish this?
