You need to detect the mime type of the file. Have a look at this question in stackoverflow..

Do the aspx, aspx.cs, web.config and accdb contain any meta data that can be read when I publish my site? (E.g. the information that can be required by reading out jpeg files).
If yes, how to view/edit this?
P.s. Except the properties shown in windows explorer of course.
Thanks in advance.
Whatever is in your aspx file, that's all what is there.
If you have added some metadata there (usually in the < head>< /head> tags), then it will be there, otherwise not.
The aspx.cs file is never really sent to the webbrowser, so there is no question of it having metadata or not.
aspx.cs web.config files are plain text files with different extensions, they don't contain embedded metadata (data which would describe the content, etc).
As for the .accdb files, you can check this question
Friends, i'm stuccoed with images in wordpress - please, help me understand where search for solution.
If you create webpage - www.wordpress.local/page1/01-0001 and you upload an image 01-0001 on that page, you can see, that when you'll visit www.wordpress.local/page1/01-0001, you'll see the page with image, not the page, that you created with text and images.
Any ideas how to solve it ?
PS Not renaming images :)
When you use the WordPress-uploader, the images are stored in /wp-content/uploads/, and WordPress takes care of using filenames that aren't already in use.
If you upload an image, e.g. via FTP, that has the same name as a WordPress-page, the server has to decide what it should serve; either the WordPress-page or the image. One URL = one file served.
In your case, the server decides for the image. You could of course change this configuration; but in all cases, one of the two files won't be accessible.
If you want to make both files accessible, you either need to rename the image or the WordPress-page.
I have a web site in which users post news to site.
so i have two field in my database NewsTitle and NewsBody.
The Newsbody can have images.
What datatype should I use for NewsBody?
I don't want images loaded from image hosting site, I want images save in my database or in my web site's host.
What is the best way to implement this, should I use ajaxcontroltoolkit?
any ideas?
You can set your the datatype as varchar as the filename of your image, since all you need to know when you try to display the image is the filename. (but of course, you must already know the location of this file)
I think u can use ListView and the template field will contain asp:image.you can store the image name in the database and bind the imageUrl through the image directory in your system plus the image name.
I am using an ASP.NET FileUpload to upload files to the server. How to upload it to the rootfolder of my project. I want to add the files to a collection or list of files to be shown on the webpage in the form of gridview. Each file should have a link to itself in the list So that it could be downloaded by the click-if desired. The gridview will also have a delete column so that I can delete any of the corresponding file-as desired. Can anyone help me to achieve this easily-without javascript or ajax
There are two ways to do it:
Simple way: create a sub-folder where you'll place your files and use DirectoryInfo.EnumerateFiles to list them.
Complex (but better) way: create a sub-folder where you'll save your files, outside of the web site, when a file is uploaded write an entry into a database, specifying the file's name (and maybe some other useful informations, e.g. size, type, etc), in your page you list the database entries, and when a user clicks on one of the links you serve the files through an ASHX handler. This way you have access control on who can download the files, and can track statistics.
