My app has broken after upgrading to ASP.NET 2.0. The problem is that Request.QueryString is empty when the SelectedIndexChanged event of a IE Web Controls tab strip is fired. It worked perfectly in ASP.NET 1. I have the tab strip contained within my own UserControl.
View 3 RepliesI have a problem that if I pass a string that contain + in a query string and try to read it , it get the same string but by replacing + with empty charFor example if i pass query like ../Page.aspx?data=sdf1+sdf then in page load I read data by data = Request.QueryString["data"] it will get as below data ="sdf1 sdf"
I solve the problem by replacing any empty char with + .. But Is there any problem that cause that ? and Is my solution by replacing empty char with + is the best solution in all cases?
Customer were getting "View State Validation Error" due to worker process recycling at our production webserver and to fix that i applied machinekey and then move my Session state Mode from In Proc to State Server to retain session data and not kick out the customer to relogin. I had serialization issue with one object which has to be stored in session but when i moved it out of session i could able to resolve the issue.
But doing all these i was partly successfull in keeping the user in their session when Worker Process recycle event occurs.I was able to refresh the page or make a post back by clicking the refresh button and also able to retain the session values. But the Problem occurs when sending asynchronous request to server which we do periodically every 15 minutes from the moment the user logs in.The web page doesnot update data on website when sending asynchronous request.By Debugging I found at this particular code point it fails to make a postback which is required.
<%=GetHintFromServer%> (When there is no Worker Process recycle i t gets replaced by
WebForm_DoCallback('__Page',message,ShowHint,null,null,false) on postback) Everything works fine when there is no Worker Process Recyling but when it happens looks like sending request asynchronously using javascript fails .Remember When I make a post back by manually clicking submit button everything works fine.
SendRequest(Asynchronous)
function SendRequest(msg, isBusy, chartMsg, vesselMsg)
{
try
{
//confirm("msg"+msg+"isBusy"+isBusy+"chartMsg"+chartMsg+"VesselMsg"+vesselMsg);
_busy = isBusy;
if(chartMsg != null)
{
//confirm("chartMsg"+chartMsg);
_element.SetMessage(true, chartMsg);
}
if(vesselMsg != null)
{
confirm("chartMsg"+vesselMsg);
_element.ShowVesselLoading(true, vesselMsg);
}
_stuckWatchdog = setTimeout( "ClearPendingRequest();", 60000);
var message = msg;
var context = '';
<%=GetHintFromServer%>
}
catch(e)
{
alert( "Exception error on SendRequest(): " + e);
}
}
Our Web Server rebooted due to power failure. Now ASP.Net State service would not start logging the following error on the server:
Unable to make the Session State Request to the session state server. Last known phase=Sending request to the state server
how to bring back the ASP.Net State service.

I'm using the new Aurigma Image Uploader Flash control, and creating sample pages works great. However, when I drop this control onto an existing page on my existing site, it doesn't work. I can only suspect something in the masterpage or something else on the page is messing with it.

I am trying to pass a key value from one page to another, using VB.net and Visual Studio 2008 Professional. I am creating a session variable in one aspx page and trying to retrive the value in the second aspx page (Dircted to by a button with the postbackurl set) However, the session object is empty when I try to access it in the second page. If, however, i put a debug hold on the code which retrieves the variable, and examine the session object from the "locals" debug window, i see contents. When I then resume the application the code retrieves the value correctly. I am executing my code using the development server that comes with Visual Studio. Could it have something to do with that?

I created three web pages: Page1, Page2, Page3. In Page1, two variables(Var1, Var2) were stored by subkeys(Key1, Key2) in a single cookie. After storing, Page1 was redirected to Page2 by Server.Transfer() as the following code:
Response.Cookies("MyCookie")("Key1") = Var1
Response.Cookies("MyCookie")("Key2") = Var2
Server.Transfer("Page2.aspx")
Similarly, I use subkeys(Key3 ~ Key5) to store three variables(Var3 ~ Var5) in Page2 and then redirect to Page3 as the following code:
Response.Cookies("MyCookie")("Key3") = Var3
Response.Cookies("MyCookie")("Key4") = Var4
Response.Cookies("MyCookie")("Key5") = Var5
Server.Transfer("Page3.aspx")
If Cookies("MyCookie") isn't rewritten by other code, it should return Var1 ~ Var5 respectively to execute Request.Cookies("MyCookie")("Key1") ~ Request.Cookies("MyCookie")("Key5") in Page3. However... Strange things happened, Var1 and Var2 were not returned, but empty string are returned instead.
Which is best option to store confidential information in a page?Control,Session,QueryString etc ... ?And also the performance also should be good ... ?
View 11 RepliesI have 2 sites, one the main product site the other a secure site featuring the basket and checkout processes.
When a user clicks "add item to basket" I am creating a basket in a database and then adding the items to the basket. The theory was then to store the id from the database for the basket (the basketid) in a cookie, redirect the user to secure site, use the basket id from the cookie and display the contents in the basket.
However I am having trouble getting the secure site to use the same cookie. When I redirect the users to the secure site, the basket appears empty. I need to go back to the main site and then back to secure before the cookie appears.
Here is the code for the cookie
[Code]....
And then on the secure site this is how it gets the basket ID from the cookie

But like I say it's having problems. I've tried replacing the cookies with session variables as well but it didn't work.
How do I create random value cookie for each Page Request in ASP.Net CS file.
Random value cookie should have server path.
These are not a kind of Sesison Or QueryString so what are them for ? I can get key names and values via Request.Form.Keys and Request.Form[i] but is it another kind of passing values something like session or querystring (post and get) so what is Keys ? Post or Get values? or another type of variable handling? can some friend explain this is useful for what ? what is the obvious difference Keys against QueryString and Session ? are they cookies or what ?
