I have a class that maintains a static dictionary of cached lookup results from my domain controller - users' given names and e-mails.My code looks something like:
private static Dictionary<string, string> emailCache = new Dictionary<string, string>();
protected string GetUserEmail(string accountName)
{
if (emailCache.ContainsKey(accountName))
{
return(emailCache[accountName]);
}
lock(/* something */)

View 1 RepliesWe have a requirement to post the status of installations on a Web based map. I remember seeing smething like this at the Visual Studio 2010 launch event. As I recall it was a Silverlight based web service.Has anyone done something similar?e.g. US Map, with GREEN/RED/YELLOW circles on specific Cities or GPS coordinates showing current status overall. Click on the Circle and filter down to the specific item you are looking for the status on, and would show Equipment installed, Progress complete, etc.

View 1 RepliesIn sql table I have fields which needs to be mapped with ALIAS field names. How to do the mapping when coding. Currently I have
select *,,data_type from mappingtable,information_schema.columns where where mainfield='City' or aliasfield ='City'
execute query using reader
This table does not contain the actual data
Its contains onky the mainfield and its alias field name
I get City from a variable
I have a second table which contains mainfield ie the column names & the actual data then I use
if( reader["data_type"].ToString() == "numeric")
do something and so on
make label control visible true
else
make dropdown visible true
but there is lot of performance and speed issue. What would be the correct method so as to enhance the above...
I have some class that I am using as profile:

I need to store some Dictionary in aspnet_Profiles table, so I decided to use some SerializableDictionary instead of regular Dictionary.. [Code]....
The question is - how can I rewrite SerializableDictionary class to use custom serialization (not XML)?
I have a dictionary with a bunch of keys and values. Keys are - descrip, department, category and item. Every key has an associated value.
Now I am trying to bind them to a check box list and I am not sure how to do this
foreach (Dictionary<string, object> dict in mods)
I'm trying to execute an aspx page but get this error.
Server Error in '/' Application.
The given key was not present in the dictionary. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

We're developping an application that uses forms authentication and URL rewriting (www.urlrewriter.net). In order to make extension-less URL rewriting possible we had to add a default application mapping for the asp.net aspnet_isapi.dll.
The problem we're experiencing now is that when the website is accessed by http://www.myapp.com/ then the aspnet_isapi.dll gets the request and forms authentication forwards it to our login site, so the user gets redirected to http://www.myapp.com/login.aspx?ReturnUrl=%2f instead of having default.aspx displayed (which is allowed to anyone).
Here's the part of web.config dealing with forms auth:
<system.web>
<authorization>
<deny users="?"/>
<allow users="*" />
</authorization>
<authentication mode="Forms" >
<forms slidingExpiration="true" cookieless="UseCookies" defaultUrl="default.aspx" loginUrl="default.aspx" name="gzfb_site_test" timeout="525600"></forms>
</authentication>
</system.web>
<location path="default.aspx">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>
I did quite some research on this problem but didn't find any solution. Is this scenario possible at all, or does default application mapping and forms auth using <deny users="?"/> interfere by design?
P.S. the problems only manifest when running on IIS 6, the ASP.net Development Server handles it without any problems
I found a example of this but it wont work for me. So I will do a clean question by asking how do I bind a dictionary to a repeater?
I work with code behind so its for the OnItemDataBound. My Dictionary look like Dictionary<string, string>();
I have 10 000 000 words, I need to use
[Code]....
to search for specific word. It is very quick in finding the word, but when loading that amount of data to my dictionary it takes a while. Could you say what is the efficient way deal with such data? This is not homework or work related, but it is my personal project.
I'm trying to move to a DataList control of a dictionary list
Dictionary <string, List <string>>
where should I insert the key and the list nell'HeaderTemplate nell'itemTemplate, but I do not know how.I tried to create the ItemDataBound event:
[Code]....
but it gives me error code sula first lien and tells me that there is no reference
I'm new to c# and .net but I think what I'm trying to do is fairly simple, however I think I'm getting stuck on variable types.So I have say 6 literal webcontrol myReq1, myReq2, myReq3.... and rather than implicitly setting them line by line I just want to run through a loop and set them dynamically. So to do this I've set up a dictionary that will contain the name of each literal, I can then run through those to add the data. This all works when I set up the dictionary by hand ie
Dictionary<int, Literal> myReqDict = new Dictionary<int, Literal>();
myReqDict.Add(0, myReq1);
myReqDict.Add(1, myReq2);[code]...
Obviously the Text inserted would be dynamic too, but you get the idea, so all that works just fine, but I'd like to do the Add part of the dictionary dynamically as well and that's where I'm running into trouble, I want to do something like:
Dictionary<int, Literal> myReqDict = new Dictionary<int, Literal>();
for(int cnt = 0; cnt<7 ;cnt+= 1){
myReqDict.Add(cnt, "myReq"+(cnt+1));
}
However this isn't valid, I can see why the "myReq"+(cnt+1) would not be valid as it's a String rather than a literal, but how can I convert the String to the Literal? What I am confused about is why the cnt on Add also isn't accepted, it is typed as an Int so to my mind it should be accepted
I've got a Dictionary<string, string> object I'm creating:-
[Code]....
and I wanted to bind this to a dropdownlist. I know this is possible in code-behind, but is it possible to do this directly on the asp: control, something like
I have a Dictionary and I bind it to my Grid view...
[Code]....
But its not paging at all... is it even possibe to page if you are bound to a Dictionary?
how can I specify DataKeyNames for a GridView when using a dictionary as DataSource?
[Code]....
In this example I would like to use "cat", "dog", "llama" and "iguana" as DataKeys for the four rows.
I have ListView control on my page, and i bound it to Dictionary<string,DataTable> generic.Now i'm trying to put DataPager on my page to support paging, but DataPager doesn't work properly, in particular, I have to click twice to move to next page, or first few records repeating thru every page. What's the problem, what am I doing wrong? I used ListView control before with ObjectDataSource and it worked just fine. Now I'm using Entity Framework to retrieve data frm Db.

I am using a xml file to get some values.
I am reading xml like this
Dataset ds = new Dataset();
ds.readXml(Server.MapPath("XMLFILE.xml");
I want to know that is this a better method to read xml file or storing xml path in web.config file and then using it is a better choice.
In Area VIPUsers I have controller ProfileController and other controllers.
If I want every method in ProfileController to have parameter (id) and every method in other controllers to have parameter (userid and id) how would I map it?
Would it be
context.MapRoute("ProfileMapping", "VIPUsers/Profile/{action}/{id}",
new {controller="ManageUsers", id=""});
and then map a default one for all the controllers?
context.MapRoute("Default", "VIPUsers/{controller}/{action}/{userId}/{id}",
new {action="Index", userId="", id = ""});
If I go to a page on ProfileController and give it two parameters after {action} (VIPUsers/Profile/SomeAction/4/4/), it'd use the second mapped route. Is that correct?
So I am working with a database and am trying to get my model code working.I have a situation where I have a table called accounts that for simplicity has 3 columns
accountid, accounttype, parentid
basically its a parent child relationship. if parentid is null its a parent, its not its a child of the accountid.Im running into problems getting the .edmx file mapping. parentid is a foriegn key on the table.
how can access the parentid column? i can see it in account navigation account1 but Im not sure how to get access to it in my linq query
