Hi friends,
Can anyone help me in finding out a suitable algorith which will create distinct cipher each time?
For example if I give Encrypt(5)and if I get value s 2
when I give next time Encrypt(5) I should not get 2, I have an application where values can be {1,2,3,4,5}, I dont want to store it plain text in DB, if I encrypt, I have to make sure by any chance one who enter into DB can compare the encrypted values and reach in conclusions, is it possible by any means to avoid it?, I should be able to decrypt also, through program, I mean encrypt with respect to time or anything?
Thanks in advance!!!
Cheers

In my asp.net 1.1 application i have 4 ListBoxes i.e., Category1, Category2, Category3, Category4.
if u select Category1, it will finds from DB and populates in Category2 ListBox. liket this i am populating Category4.
Here Each Category is having CategoryName, CategoryID and its languageid(each category is having each languageid).
I want to avoid the DataBase Trip each time.
My question is how to cache the whole data & How to retrieve the data from cached. We can store in 4 different Sessions also. but in which format to store(it is having name, value1, value2)
How to do this? anybody give me the solution for this.
?
regards

Create a datatable, pump the data in that and then put that datatable in session in order to reuse it.

Or save it all on the client side (if you don't like your users) in javascript array - this way you can use script to populate the listboxes at runtime, avoiding postbacks.

There are a number of ways that you can attack this problem. The correct solution depends entirely on the nature of your application. Our developers usually create some sort of "Cached Items" class that manages data within a cache. If your data set isn't too large, you may want to store all of the unfiltered data in a single data set and use the DataRelation to define the relationship among the tables in the DataSet used to populate your ListBoxes. Whenever a list box is changed, use the relationships defined in your filter the data as needed and rebind the filtered data to the list boxes.
For example, you could so something like this:
intenal static DataSet Categroies<br />
{<br />
get<br />
{ <br />
DataSet data = HttpContext.Current.Session["CategoryData"] As DataSet;<br />
if(data == null)<br />
{<br />
data = <br />
HttpContext.Current.Session["CategoryData"] = data;<br />
}<br />
return data;<br />
}<br />
}<br />
<br />
internal static GetCategory2Data(string category1)<br />
{<br />
DataView category2 = Categories.Tables["Category2"].DefaultView;<br />
category2.RowFilter = string.Format("Category1 = {0}",category1);<br />
return category2;<br />
} <br />
Here data is being stored in the session. You could also use the Application or Cache object to store the data globally so long as you account for multi-threaded/multi-user access into account.

Hi! I'm using ASP.net 2.0.Sometimes a file named App_Offline.htm gets created by itself, which displays message that application is currently offine. Any idea why it gets created automatically or how to stop this? Thanks a lot.

I guess this kind of things will happen
1. when your hosting server receives the more than requestlimit and size
2. when you workprocessor size limitation occurs.

I want to show message page has expired when clicking on Back button in

I tried
Response.AddHeader("Expires", "Mon, 26 Jul 1997 05:00:00 GMT")
Response.AddHeader("Last-Modified", Now & " GMT")
Response.AddHeader("Cache-Control", "no-cache, must-revalidate")
Response.Cache.SetCacheability(HttpCacheability.NoCache)
But it doesn't show the message i want to display.

This is how you can get that:
DateTime dt1 = <some date="">;
DateTime dt2 = <some other="" date="">;
TimeSpan ts = dt1 - dt2;
int days = ts.Days;

Use the Substract method of the DateTime object to get the difference as a TimeSpan. The TimeSpan structure has properties that you can use to get the number of days.

Dear guys,
Can any one helps me in my case study.I will be very great full.Please take a look at following project description....
**************************************************************************
Description:
Develop a client and server application to synchronize data between one another.
Client application runs on Windows based OS XP or Server and is written in .NET 2.0/C#. Client application monitors users PIM (Outlook, Outlook Express, etc.) for changes to email, contacts, tasks and communicates any changes to server application. Additionally application monitors listing of favourites from Internet Explorer, FireFox, etc. and synchronizes with server.
Server application runs on Windows Server and is written in .NET 2.0/C#. Server application accepts requests from client application to update data from users PIM and browser and stores in MSSQL 2000 database. Communication between client/server is RSS and server uses web service to process requests.
Client application checks for changes in the server side database and updates or synchronizes local PIM and browser with what is stored on the remote database. Server application uses keep alive link from client side to communicate to client that it needs update from the client side.
Client application needs to be modular to accept future enhancements to manage other PIM applications or browsers.
The server manages several clients and runs in multi-threaded, multi-user database environment.
Please respond with your technical plans to accomplish the requirements of the application.
1. What technologies will you employ on the client and server side.
2. How will you accommodate the remote communication mechanisms.
3. What client side PIM applications will your program support? (Outlook, Outlook Express, etc?) What browsers will you support?
4. How will the database schema accommodate the multi-user environment? Changes in information on either side? and Synchronization?
5. How will both applications be designed to be bug-free, crash resistant, and recover from errors?
*************************************
I will be very great full for any response
Thanks Alot
