Hi,
I have an image, file upload and a button control on my webform. I am uploading a new image and attaching the image to replace my existing image in button click event. It seems to work fine on my local machine. When I deploy and run on the server side, the image upload is working fine, the image is getting replaced in the background. However my web page still shows old image. If I reload the page then it shows the updated image. I am using the same name for the image when I am doing save as in the button click event. Any inputs why this is happening?
Appreciate inputs

Because you are manually refresing the web page.
For example, if you had a function in your script block to refresh the images in every 15 seconds in the web page, you wouldn't have to refresh the whole page to see if the uploaded images sucessfully replaced. Just an idea...
What a curious mind needs to discover knowledge is noting else than a pin-hole.

Because the browser has cached the page and your seeing that cached page. You have to set metatag information telling the browser to not cache the page or shorten the time that the cached page is valid.
I have no idea how to do it because I don't do that much web developement. Your best bet is to ask in the ASP.NET Forum.

We have a window service which sends mail.
Now we tested the application by adding our internal and external email addresses like (abc@yahoo.com)
When we created the "To" part from application both the address were shown and application send the mail withoout any exception.
Now the problem:
We checked both the email a/c. We did recieved the mail in the internal a/c but not in the external a/c.
When we send the same mail from outlook then we recieve mails in both the a/c
We checked the logs in the exchange and we found out that in the "To" part there was no external email a/c while sending it from application.
But it was while sending it from outlook.
How come exchange behaves differently when we send it from application and when we send it from outlook.
What can be the likely problem

Just copying your homework assignment is not a sufficient description of what you need help with.
You have to ask specific questions about what you need help with.
Also you should explain what kind of assignment this is, so that people gan give the proper guidance. If people think that you are trying to trick them into doing your homework, they will not give you any help at all.

It's simple. For example, You can just provide a simple class that have a List that contains the grades of students (an example, a List of custom classes that provide name/surname of student and the grades) and simple methods to calculate the average/highest/lowest grade.
Another way may be to use a database, DataTables, XML etc...
To test the class you can provide a windows form in that show the grades for each student (for example).

I have various ODBC datasources visible in the User DSN and System DSN screens in the ODBC administrator applet. However, although these show fine in the EXCEL data query screen, these data sources don't show up in the choose datasource screen from the add new database choice in vb.net.
What am I missing?
Thanks!

Ok I was looking at some directx documents that meantion the IntPtr structure. Is this just a pointer? And if so how do you set where it points at and are there any limitation on how you can use it, and is it as fast as pointers? For instance if I said myintptr = myvar would that set myintptr to myvar's value or its location?
thanks for the help,
Mike

The IntPtr structure is used to handle pointer values in managed code. If you want to set the value of an IntPtr, you have to use the & operator to get a pointer value, but that can only be done in code marked as unsafe.
For regular managed code .NET uses references instead of pointers. They are exactly as fast as pointers, as the final compiled code uses them exactly as pointers.

Hey there. Printing problem is solved. Thanks anyways
Okay in my previous programs I used to use arrays to hold the entries and information and when the program was to be terminated I used to write back them to a file by using write_ entries () procedure. In this one I want to do now, I don’t want to use this way because of the structure of the program that it follows. I want to save them instantly as the button_save is clicked.
1. Open file ( sr=IO.streamReader)
2. Read till end of file is reached (do while sr.peek <> -1)
3. Now that end of file is reached does the writing (sw.writeline)
But how we can do the writing, we can’t, unless the process of reading to be closed
Which means sr.close() and when it is closed the pointer is set again to beginning.
Writing to file now would be writing instead of the first line again.
How to change the POINTER settings? Sounds silly but i am a newbie to .NET  : doh:
How you do the writing then?

Don't bother opening the file for Read. Just open the StreamWriter for append and anything you write will show up at the end of the file automatically.
Dim sw As StreamWriter = New StreamWriter(filename, True)
The True parameter means "Append" if the file exists.
Documentation on the StreamWriter constructor overloads is here[^].

You have to check each document to make sure it is closed. You can check if any forms in the application is open.
Use
Application.OpenForms.Count
