I just posted an article under the ASP.NET section called "AJAX Demystified - Part One". It explains how to create a simple shoutbox in ASP.NET (C#) using AJAX. Hopefully it'll help you understand a little more about it!

i am a fresher in asp.net.in my project, i hav a doubt that..how to merge two .gif images in a webform dynamically?
my project is a sattellite tracking system in which there are two basic images one is a ""logo""and the other is a ""background""map. when ever i am inserting longitude and latitude values in the database, the logo should come on the map in the exact position.i should have to put many more than one logos at the same map.that is by clicking "update" button each time the map should be updated.
put some ideas ..i tried it but some image format errors are coming.pixel format and this .gif image format..

Do you have to merge the images? Can't you just place one image on top of the other?

no..its not like that...i have to merge a perticular icon in a map,suppose in indias map when the administrator is inputting the corresponding geographical measures.(longitude and latitude).
first to check whether the given measures are covering which area..after checking that it identifies that area is India.then it finds the inner exact position and merge the icon image there..(For this i am using gif images of background map(image1) and icon(image2).i want to merge image2 on image 1 when ever inserting the measurement in the database...)
TRY IT>>>ITS NOT SIMPLE I THINK>>>give me idea about grids also..that can help..

Check the following code
In this example Image2 will be added to the Image1, you need to just change the names from Images1.gif and Image2.gif to your image name.
Let me know if you have any issues.
//Code Starts Here
// This is the Original Image that is Image1
System.Drawing.Image bgimage = System.Drawing.Image.FromFile(Server.MapPath("Image1.gif"));
Bitmap bmp = new Bitmap(1, 1);
Graphics graphic = System.Drawing.Graphics.FromImage(bmp);
// measure the image
int height = bgimage.Height;
int width = bgimage.Width;
// recreate our bmp and graphic objects with the new measurements
bmp = new Bitmap(width, height);
graphic = System.Drawing.Graphics.FromImage(bmp);
graphic.DrawImage(bgimage, 0, 0, width, height);
graphic.TextRenderingHint = TextRenderingHint.SystemDefault;
System.Drawing.Image bgimageNew = System.Drawing.Image.FromFile(Server.MapPath("Image2.jpg"));
//You can set x position, y position, width and height of the second image.
graphic.DrawImage(bgimageNew,5,5,50,15);
// Set the content type and return the image
Response.ContentType = "image/JPEG";
bmp.Save(Response.OutputStream, ImageFormat.Jpeg);
// dispose of our objects
bgimage.Dispose();
graphic.Dispose();
bmp.Dispose();
//Code Ends Here

What is it not like?
I see no reason why you have to merge the images. It's not that hard to do, but why would you if you don't have to?

I don't think you can create an mdb file with this way, clikety[^], a simple way is to copy a current empty mdb file.

Hello
Call following Method in Page_Load in CodeBehind of the left Frame:
Public Sub RefreshFrame(ByVal frame, ByVal loc)
Dim sTemp As String
If Not Me.IsStartupScriptRegistered("RefreshFrame") Then
sTemp = "<script language=JavaScript>" & vbCrLf
sTemp += "if (parent.frames[" & Chr(34) & frame & Chr(34) & "]) {" & vbCrLf
sTemp += "parent.frames[" & Chr(34) & frame & Chr(34) & "].location.href=" & Chr(34) & loc & Chr(34) & ";" & vbCrLf
sTemp += "}" & vbCrLf
sTemp += "</script>" & vbCrLf
Me.RegisterStartupScript("RefreshFrame", sTemp)
End If
End Sub
This Method generates a little bit JavaScript in Code of the left Frame, that reloads the other Frame with a specific URL.

There are a couple of ways that you can do:
+ Use the Directory.SetAccessControl method.
+ Use the cacls tool and you can use the Process class to make it work.
+ Use WMI.
