We are writing a portal and like every portal we store html data in Db fro Modules. So I thought that I can cache each module in files. I use OnLoad event to check if there is a cache file for this Module, use that and else create cache file:
if (!IsPostBack)
{
string Path = AppDomain.CurrentDomain.BaseDirectory + "CacheModules" + ModuleId + ".dat";
if (File.Exists(Path))
{
Controls.Clear();
[Code]....
what do you think? retrieving data from file can slow server more than retrieving data from DB?

I'm working on an application (ASP.NET, Webforms) that generates a list of outputs based on a user input. I want to allow the user to save the contents of said list as text file, or possibly as other filetypes such as .csv. What is the best way to approach this? Can it be done client-side with Javascript?
We have a data driven ASP.NET website which has been written using the standard pattern for data caching (adapted here from MSDN):
public DataTable GetData() { string key = "DataTable"; object item = Cache[key] as DataTable;
[code]...
The trouble with this is that the call to GetDataFromSQL() is expensive and the use of the site is fairly high. So every five minutes, when the cache drops, the site becomes very 'sticky' while a lot of requests are waiting for the new data to be retrieved.
What we really want to happen is for the old data to remain current while new data is periodically reloaded in the background. (The fact that someone might therefore see data that is six minutes old isn't a big issue - the data isn't that time sensitive). This is something that I can write myself, but it would be useful to know if any alternative caching engines (I know names like Velocity, memcache) support this kind of scenario. Or am I missing some obvious trick with the standard ASP.NET data cache?
I have use Nhibernate in my MVC Project by me known, Nhibernate have cache on Session and Object. now, I want use HttpContext.Current.Cache (system.web) for cache data something in project. my code same that have problem, haven't it. and that's right or wrong.
I use shared hosting. I have set my page to be cached indefinitely. The page gets cached after the first request. However on the next day when I visit my site it is no longer in the cache and has to be regenerated.
What is happening? Is the hosting removing my pages from the cache? Or something else?
Currently we are saving files (PDF, DOC) into the database as BLOB fields. I would like to be able to retrieve the raw text of the file to be able to manipulate it for hit-highlighting and other functions.Does anyone know of a simple way to either parse out the files and save the raw text on save, either via SQL or .net code. I have found that Adobe has a filtdump utility that will convert the PDF to text. Filtdump seems to be a command line tool, and i don't see a way to use a file stream. And what would the extractor be for Office documents and other file types?-or-Is there a way to pull out the raw text from the SQL Full text index, without using 3rd party filters?Note i am trying to build a .net & MSSql solution without having to use a third party tool such as Lucene
I am using crystal report and I am exporting data to PDF. In crystal report for a particular field I have HTML text as input. So I have set Text Interpretation as 'HTML Text' for that field in crystal report. But still in PDF few things are not working. That is, it is not showing bold, and bullets etc. Underline and color and font are working fine. HTML text is :
I'm trying to add html text to some repeater items during DataBind, but the html text isn't parsed into controls it just displays as text. If I copy the text and just add it to the asp.net page it works fine so I know my syntax is fine. So is there a way to dynamically add more html text during the data-bind phase?
I've created a seperate html files for navigation, content and footer. I want to club those files. All the navigation, content, footer files resides in the same directory where the index.html file resides. I want to include the above mentioned html files inside the index.html. I have tried using the following in index.html file <!-- #include virtual="topbanner.html" -->
I also tried using the asp code which also fails. I tried with asp by changing all the html file extensions as .asp. Then i tried to place the following asp code in index.asp file as <!-- #include file="topbanner.asp" -->
I have used a rich textbox control,ckeditor in my case,When any formatting is done to the text the formatted text is populated in the datagrid.But I want to extract only the plain text in the grid and trim the length of data to 80 characters while populating.
I read few xml files from a location and cache them using Http context cache. Anytime the xml files changes i have to do a IISReset to view the latest changes.
I use this
System.Web.HttpContext.Current.Cache
I have to use the caching as i don't want to read all the xml files all the time. i read it once and caches them for a day. They get reset whenever apppool recyles or anyone manualy do a IISReset.
Is there anyway in asp.net to invalidate the cache if someones changes the xml file.
I have asp.net application. I'm using external javascript files in my application. When I test my site with page speed tool from google it says that following resources are missing a cache expiration. also some of the images and css files.
I configured cache dependency on a file on the server, the cache dependency event stops responding to file changes once in 2 or 3 days. After I perform IISReset on the server, it works fine.
where external files / images are being loaded from. By this I mean that I'm aware that external JS files / Images are cached on the first load of a page. What I'd like to have is a tool that confirms to me that on subsequent requests these files are in fact being loaded from the users cache rather than downloading the file again.
I have a navigation on my site that retrieves it's links from xml file..Does asp do this everytime a link is clicked on my site..I'm using a master page and the navigation code within the master page is below..So is the xml file opened and read each and every time? any way to cache it or something.below is my code
I'm new to ASP.NET. I 'm trying to figure out how to make an HTML/ASP page where a user puts in data, either in text fields or selection boxes, and on clicking a submit button all of there selected data gets dropped either into a Access 97 Db or an excel spread sheet. Are there any examples out there of this? Is there a place that has already created this and I can just look and the code and figure it out for myself?
I am using swfupload to upload files on a website, the problem that every time the user open the page which contains the upload button, the page loads completely then the flash file start loading from scratch every time the user visit the page with no cache. Is there a way to preload and cache .swf files in my asp.net page?
