ASP equivalent of Ajax? - asp.net

Question

Weird question. I need to use a JavaScript array with ID's in it, to fetch additional information from a database, using the ID's as the row ID.
I need to then use this additional information and send it to another file (aspx) using Ajax, which will then use this information to rotate images.
Unless I can use ASP Classic, and ASP.NET (C#) in the same file?
- Or can I use the more or less same ASP code to access my database?
rotate script
<%# Page Language="C#" Debug="true" %>
<%# Import Namespace="System" %>
<%# Import Namespace="System.Drawing" %>
<%# Import Namespace="System.Web" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
//string url = Request.QueryString["url"];
string url = #"C:\inetpub\wwwroot\testing\image.jpg";
string rotate_dir = Request.QueryString["dir"];
//create an image object from the image in that path
System.Drawing.Image img = System.Drawing.Image.FromFile(url);
//Rotate the image in memory
if (rotate_dir == "clockwise")
{
//Rotate clockwise
img.RotateFlip(RotateFlipType.Rotate90FlipNone);
} else if (rotate_dir == "anticlockwise")
{
//Rotate anti-clockwise
img.RotateFlip(RotateFlipType.Rotate90FlipXY);
}
//Delete the file so the new image can be saved
System.IO.File.Delete(url);
//save the image to the file
img.Save(url);
//release image file
img.Dispose();
}
</script>
What I use to access my database
'Create connection and load users database
set conn=Server.CreateObject("ADODB.Connection")
conn.Provider="Microsoft.ACE.OLEDB.12.0"
conn.Open Server.MapPath("/nightclub_photography/data/database/jamsnaps.mdb")
Hope you understand what I'm trying to do?

As you should know you can freely use Javascript (and thus ajax) in asp-classic.
this means you can easily do the following;
set conn = Server.CreateObject("ADODB.Connection")
set rs = Server.CreateObject("ADODB.Recordset")
conn.open Server.MapPath("foobar path") + ", Microsoft.ACE.OLEDB.12.0"
%><script type="text/javascript">
rotationArray = Array(id_Array.length);
for(int i = 0; i < id_Array.Length; i++
{
<% rs.open("SELECT rotation FROM images WHERE id="+ id_Array[i])%>
rotationArray[i] = <%= rs("rotation") %>;
<%rs.close() %>
}
//send rotationArray via ajax
but in general I would suggest you use Database tools for asp.NET instead.
then you just send your JS-IDArray to the aspx file and do the processing there.

You can use C#.Net and ASP together. Its not a very nice way to do it. My understanding is you have to create the C#project first then add any asp pages. This will allow you to call your C# pages from within the asp application.
I havent personally done one of these but I have seen it done for sure so I know its technically possible.
