Don't post a question more than once. We're able to see it.

Create a page property that references that control. Then access that property from the other page.

Hi All,
My problem is to find the size of an Image file using JavaScript. I have some codings for that. But because of ActiveX objects, my code is not working. How to enable ActiveX objects in ASP.net or Internet Explorer(?) Help me please...

Hi Friends,

I am facing a very uncommon problem in my web application in asp.net (using vb.net). I am taking screen shot of screen using "BitBlt" Function of Library "GDI32", after getting screen shot this is stored in a Bitmap object and this object (after converting to Byte array) is stored in SQL Sqrver Database Image Field.

Now on another asp.net page i retrieve this Byte array and again store it on Bitmap object and then i write this object on the page using Response in this way:-

---------------------------------------------------------------
Dim ms As MemoryStream = New MemoryStream(imgbytes, 0, imgbytes.Length) 'imgbytes is the Byte array containing Bytes from database
Dim im As Bitmap = Bitmap.FromStream(ms)

Response.Clear()
Response.ContentType = "image/jpeg"
im.Save(Response.OutputStream, ImageFormat.Jpeg)
---------------------------------------------------------------

When i run my project on localhost everything work in perfect way.
Now my problem is that, when i upload this on my server and run this project a Black Image is displayed in place of saved image.

There is Link to this project.

If any one has any idea how to capture screen of client computer.
Please help me.

Session Retention using WebRequest + WebResponse

1-Dec-06 3:19

The screen shots are probably executing in the context of the IIS user.

I, for one, would be worried if this functionality actually worked. What's to stop a website from taking screenshots of everyone's desktop that visits their page?

Hi,

I'm trying to implement a WAP front end for a Website, but the website i am trying to wrap requires an active session for users to use it.

I've created the WAP pages on a seperate server and have the requests sent to a worker process that processes the live Webpages. However, using the WebRequest and WebResponse, i can't seem to maintain an active session (I'm re-creating a new instace for each request).

How would i go about retaining a session between multiple requests? OR, how can i use a single request object to make multiple consecutive request?

Any examples or articles would be appreciated.

Cheers

Tris

You must retrieve the CookieContainer of the first response (HttpWebRequest object) and retain the CookieContainer for the subsequent requests

If you are using HttpHandler, then you need to have IRequiresSessionState interface (marker interface) to be implemented.

Then the automatic WebRequests would pass through.

There are many posts for this exact question. This is obviously homework.

ed^nrgc1-Dec-06 2:55

You might want to look into why the page is taking so long, instead of a hacky workaround. Nice school you're going to.

333soori1-Dec-06 3:31

there are around 3000 records , that's why its taking time to reload the page

People here frown upon doing homework for others. You should NEVER change the cursor to an hourglass through postbacks. It's a horrible practice.

If you know how to do it, then call the javascript function when it starts loading data.
