How can I add a file upload button to my website?

Something like

<form method="post" enctype="multipart/form-data" action="http://example.com">
<p>
Please specify a file:<br>
<input type="file" name="myfile">
</p>
<div><input type="submit" value="Send"></div>
</form>

In web application do you mean asp.net ?

If so, you can use File Upload control.

<asp:FileUpload ID="FileUpload1" runat="server" />

On client side add this to your form:

<asp:FileUpload ID="FileUpload1" runat="server" />

and on server side write this byte[] to a database field:

FileUpload1.FileBytes

use this

<input type="file" name="datafile" size="40">

indside a form.
