Then the operator/user on the server clicks on the second slide and the laptop would now see the second slide. Is this possible to do? If yes, then what technology to use? DHTML? or something else.

We are making a site in asp.net 3.5 C# and i am showing my all user activites on one page (i am making a call to db at page load) but to get updated user activities i have to refresh the page so that again one hit go to the db and get all updated data.

View 5 RepliesI have a web parts page in which each web part has its own personalization data(list of DB table primary keys). At startup, I want to get thecombined data stored in each web part to make a query in the background. Is it possible ? Currently I have to wait for IPersonalizationData.Load for each web part to get what keys are stored by each. Is there a way to store personalization data for the whole page ? I can't use profile as this data is not per user. Worst case is write to a file which I want to avoid if possible.
View 2 RepliesI have an asp.net page that will be doing some processing that may take a very long time to complete. I cannot just set the page timeout value since this is going to be in a hosted environment and the timeout values that I set in my web.config are overridden by the server host. What I'm doing is taking a file from a FileUpload control and doing some web requests to a 3rd party service for each line in the file, all of which may take a very long time to process a large file. I'm talking on the order of, say, 30 minutes, and there's just no way to optimize this any further to cut down on the processing time. Is it possible to even do such a lengthy page request in asp.net? Can someone give me a pointer in the right direction here to make this happen? Is my only hope to create an async page? It seems that doing an async page is the way to go if I have a potential for a lot of lengthy requests, but really this massive of a request is going to happen VERY rarely so this is not an issue of running out of thread pool since most of the time this particular request will be completed relatively quickly, but on occasion it may receive a very large file it will need to process and will take a very long time. So what is the best way to handle that case?I'd also like to update the client with the processing status as the processing is going on. I'm familiar with doing client ajax calls via jQuery to a page webmethod so if there is some clean way to update the client as this long processing

View 9 RepliesIs it better to store images directly in a database or to just store the name of the file in the db and display that file? I would think that just storing the filename of the image would keep the db size low...
View 1 RepliesWeb service error response (code/message etc) would you store it in a database? or would you keep the error response in a method.By the time I'm done with this, there will be hundreds of error response, maybe in the future, thousands? (I dont know yet, depends how large this web service grows).EDIT: error response is the response returned back to the application via the web service, (not to be confused with error logging).

and what control i use in this in C sharp
I am having an issue with content page refresh, when I change something in master page. My scenario is, I have a login button present in master page, on click of which am loading a modal popup with login controls. Once the credentials are valid, i am hiding the modal popup and stroing the user authentication result in a Session object. In content page's page load event, I am checking for this session object, for showing/hiding some of the controls based on the user logged in.The problem is, after login, the content page is not getting reloaded and proper controls are not shown to the user. To make the content page refresh programmatically, i added an UpdatePanel in content page and refreshed it after login button click event in master page. But still content page is not getting refreshed.
btnLogin_Click(){
//Check login credentials
if(success){

I am a beginner to web development and ASP.NET. I am creating a web application (not public, so SEO, bookmarking etc. is of no concern) with the typical layout of header on top, Navigation on the left, content on the right. I want the content to update without the whole page reloading when selecting something on the navigation bar. What is the typical way to implement this? MasterPage with ContentPages and using an UpdatePanel (tried this, but does not seem to work, I guess because the URL is different for each content page)? Using Frames? Using an iFrame for the content part? UserControls for the content part
View 5 RepliesI have a command line C# server and an ASP.NET client, they both communicate via .NET Remoting. The server is sending the client still images grabbed from a webcam at say 2 frames a second. I can pass the images down to the client via a remote method call and the image ends up in this client method:
public void Update(System.Drawing.Image currentFrame)
{
// I need to display the currentFrame on my page.
}
How do i display the image on the a page without saving the image to the hard disc? If it was a winForms app i could pass currentFrame to a picturebox ie. picturebox.Image = currentFrame.The above Update method gets fired at least 2 times a second. If the client was a winForms app i could simply put picturebox.Image = currentFrame and the current frame on the screen would automatically get updated. How do i achieve the same effect with ASP.NET? Will the whole page need to be reloaded etc?
