I am trying to fix the size of the Hashtable with following code.
[code]....
I have fix the size of this Hashtable is 2 but I can add more than 2 elements in this, why this happen, I am doing somthing wrong?
I have tried to find out is this Hashtable have fix size of not with hashtable.IsFixedSize, it always returns false
i'm retreiving data(API) with JSON format and i'm parsing it inside a hashtable,it seems like some specific keys have a value= hashtable(or arraylist!)below is how i'm extractin the the first layer value
[Code]....
the problem is where the values are equal to arraylist i'm not able to extract themIs there any way to extract the second layer keys and values?<i> (btw i'm very new to hashtables and arraylists)</i>
I am building a Asp.net Application. I need to save a HashTable in a session.
At page load i am writing
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Session["AttemptCount"]=new Hashtable(); //Because of this line.
}
}
Here problem is, when a user refresh the page, session["AttemptCount"] also get refreshed.
I want to know where should I declare
Session["AttemptCount"]=new Hashtable();
So that my seesion do not get refeshed.
EDIT In Global.asax, this session will get started, as soon as user opens the website. I want to creat this session only if user go to a particular page. i.e Login.aspx
I have a problem while checking a hashtable value. In the code below I am storing 60 values in the hashtable "hash". One of the values is (or can be) Null. I am checking each entry against its corresponding entry in hashtable "hash1", to see if they match each other. If they don't match I want to check if the value in "hash" is Null, but I can't catch it - it's falling through the 'else' part). How can I overcome this problem?

reasking some basics to clear out from this messed up things
1) difference between using normal array & using hashtable in terms of storage, access speed
2) is it possible to store values from serverside controls in javascript on client side in a normal array variable ( values can be of different types) even on postback??.
if yes how
3) currently i have hidden fields which stores values on client side and on postback saves in hashtable ie saving data on server & not on client.
I have a screen and in the code behide i have private class created inside the pageÂ
In this class i have a HashtableÂ
i will like to pass this hashtable from one screen to another by QuerystringÂ
1) As per my understanding, Session variables like HashTable and another variable in Session must be initialized. The best place as per my knowledge is Sesson_Start Event. But at some post its written that we must do that in Application_Start. I think it is not true, as that could lead to problems with different user sessions. Reference is this [URL] Let me know about the concept.
2) Storing variables like string, boolean and etc in Session is slower than storing objects in Session like HashTable, Arrays etc.. becuase they dont require boxing and unboxing. Is that true? Reference. [URL]
We are using static hashtable in webservice for sharing common data among different users. Is it safe? Is there any better way?
View 1 RepliesI know the content palcehlder does not have a size ,I have a masterpage and content page, the master page has a table with a header, content area, and footer, header and footer are fixed size, content area is 100%. As the user sizes the browser the content area grows and shrinks and the footer stays at the
bottom of the browser window - perfect!
Problem: The contentpalceholder does not grow to fill the available content area. Now, the contentplaceholder gets its size from its contents, which in this case is a div holding a silverlight object.I was thinking I could hook the master or child page's re-size event and somehow pass that info onto the SL object, but as it turns out (and I'm surprised I never knew this) there is no aps.net page re-size event! (really?, wow.)
So is there a way to get a SL object hosted on a master page to size itself based on the size of the browser window?Or more generally, a way to size the contents (like a div or panel) of a contentplaceholder based on the browser? on a standard aspx page (not a master page) I CAN get the SL object to size itself based on the broswer, the problem seems to come from the fact that I'm hosting the SL object in a content placeholder.
I guess I could 'unroll' the master page into several standalone pages and have it work, but the menu is on the master page and I'm used to using them, plus it's already done...<sigh>
I am using TabContainer with some controls on each tab (asp: labels, text boxes). When redirecting to the page that contains the TabContainer, the tabs and their content loads as expected, but when there is a postback, and the page refreshes, the TabContainer UI changes - the font size of the labels gets bigger, the text boxes become bigger and their location changes a bit (not aligned as before), and the tab header is partially hidden. I am using IE7.
I dont know if this is relevant but in some of the text boxes i use edit mask extender as well for date. Also, I have used a table inside the TabContainer for layouting the controls.
I am using PageMethods to send a few parameters to a webmethod in my codebehind. The method runs a stored procedure and uses the results to build a string that I am returning from the method.
Everything works fine until I try to include too many records in my results..
Once the results I am trying to return hit about 70K, the pagemethod times out even though it is taking about 1 second to process the results.
Is there a buffer limit or limit on the size or results returned from a pagemethod and if so, where can this be set or changed?
Is there a setting in the web.config somewhere to handle pagemethod buffer size?
In login.aspx I have used login control to enter user name and password, the problem is: even my caps lock is off when I enter user name it prints in capital letters but size is small size (when I copy and paste in note pad or msword it paste in small letters not in capital letters), when I turn on my caps lock on and type - it prints in bigger size as if I am typing in capital letters.
ex: 1. temp is my user name if my caps lock is off it shows like this TEMP (but size in smaller than 2nd one)
2. if my caps lock is on is shows like this as if I am typing capital letters TEMP
what do you think the problem is how can I fix it
As I know, by default Cache is stored in the memory and to the disk at the same time DiskCacheable=true).When the cached response is removed from the output cache due to memory pressure, it still remains on disk allowing a much larger set of pages to be cached. In addition, disk cached pages survive application restarts. And this is already in ASP.NET 2.0.I dont't know in which order the caches are removed from the memory and readen from disk instead? I would like to achive, that caches with the minimal trafic, or the longest last used, would be removed first from the memory. Is there some settings to do that, or even by default works that way?
View 1 RepliesHere's the scenario:I have an asp.net webpage which displays dynamic data in a gridview.I'm using a master page to display the header and footer of the page, and this gridview is being displayed inside a div in the contentplaceholder.
The Problem:What I want is that the size of the page that is displayed remains constant for a user and must be equal to the size of their browser's available display area and the content being visible by scrolling the div.Sort of like the header and footer remain at the same position and the content inside it is scrollable.
according to the developer of the web service I am calling.He said "bump up the default values for the following":
maxBufferSize="4096000"
maxReceivedMessageSize="4096000"
Where can I put these to bump them up? I've tried googling these settings, and I get sections of web.config that I don't have. I don't have a WCF client, either. Does this make sense to do from my web service, developed in VS 2010?
I'd like to just call his service without changing anything, get the error, and then go from there. I'm even getting that far because I got some other exception saying server was unable to process request, but it had nothing to do with exceeding a buffer size.
I have defined a public static HashTable. It stores data for a few seconds of runtime, and then data disappears, and then the HashTable becomes null.What is the issue and how do I solve it?
View 1 RepliesI am looking for opinions and best coding practices.I need to get info from a database with a query such as SELECT this, that FROM MyDB (returning 2 fields). Would it be wrong to use a hashtable for temporary storage?Is there a better way to accomplish the same thing? What about if I am returning more than 2 fields, would it be best to step up to a DataSet or something?
