There are several methods you can use to control the types of files that are uploaded to the server. Unfortunately, there is no bullet-proof method to protect you from someone uploading files that would be considered malicious.

You can take a few steps, however, to make this process of allowing end users to upload files a little more manageable. One nice method you can employ is to use the ASP. These controls enable you to do a regular-expression check upon the file that is being uploaded to see if the extension of the file is one you permit to be uploaded. This is ideal for browsers that allow client-side use of the validation controls because it forces the checking to be done on the client; the file is not uploaded to the server if the signature isn't one you allow.

Listing 3 shows you an example of using validation controls to accomplish this task. Listing 3. Using validation controls to restrict the types of files uploaded to the server.

This simple ASP. NET page uses validation controls so that the end user can only upload. If the file type is not one these three choices, a Validation control throws an exception onto the screen. This is shown in Figure 4. Using Validation controls is not a foolproof way of controlling the files that are uploaded to the server. It wouldn't be too hard for someone to change the file extension of a file so it would be accepted and uploaded to the server, thereby bypassing this simple security model.

You just saw an easy way to add some ASP. NET page to perform a client side validation of the file extension in just a textual manner. Now let's take a look at how to perform a similar operation on the server-side. It is used for finding the beginning of frame. But these values can occur many times in binary file so you should test next values from header for validity eg. Next method is to find the first header and then go through all frames - almost exact, but time consuming.

Be careful with the first frame! It doesnt have to start at the first Byte in file. Either TAG v2 can be included or file can contains of some crap at the beginning.

Anyway - to find a header is a little problem. To fix this issue for others working on similar projects, I created a small WinForms project using C and Visual Studio to demonstrate how to not only save files into a binary field type, but also how to retrieve them. SQL Server allows you to create a field type known as a " varbinary " type. While you could just store a string value for a file path that would serve as a "link" to the actual file on a file system, you would need a separate file storage area for your application and a way for the front end to connect and manipulate the files.

Instead, a SQL Server field type like varbinary max will allow you to simply store the file just like any other type of data in a table — right alongside metadata stored in companion rows to make a meaningful record.

To make full use of this code, you will have to create a database like the example in the article or mount the example one provided, as well as update a connection string in the main form code.

This project also assumes you have Visual Studio Express C or better. There are three main queries in use and they are defined as string variables. Send via email option once uploaded.
