I have to different .Net applications running simultaneously. Assume both are windows / web applications.When I update some data in application A
correspondingly data in application B must be updated.
I have a web application (MainApplication) where many of the pages contain a custom Web Control that looks for some content in a cache. If it can't find any data within the cache, then it goes out to a database for the content. After retrieving the content, the Control displays the content on the page.
There is a web application (CMS) in a subdirectory within the aforementioned web application. Users use this CMS to update the content pulled in by the MainApplication.
When a user updates some content using the CMS, I need the CMS to clear the relevant portion of the cache used by the MainApplication. The problem is that, as two different web applications, they can't simply interact with the same static cache object.
The ideal solution would be to somehow share an instance of a cache object between both web applications.
Failing that, what would be the best (performance-wise) way of communicating between the two web applications? Obviously, writing/reading to a database would defeat the purpose. I was thinking about a flat file?
I begin with MVC and this technology is very efficient !
I would like to create several applications mapped with a common applicaton Users Accounts. The aim is to isolate logical parts. The problem is always the same : how to communicate easily between users db and appli db ? Do I continue to use my poor View mechanism from SQL Server (db1.Users.UserId inner join db2.Users.UserId) or is it a better way with super MVC?
I have multiple projects that need to share resource files (.resx) Suggestions have been made to move resource files to a separate assembly and have web projects reference it. Is there an example of how to do this?
Do I create a new Class Library project and move App_GlobalResource folder inside of that? I don't think that will work because code classes that are generated for resource files are marked as 'internal' which means that they can not be accessed outside of this assembly.
Is there a way to share cookies across different domains and different applications (classic ASP and ASP.NET)
View 4 RepliesI have 2 almost identical asp.net (vb) applications. 1 Development and 1 Production.
They use forms authentication that is configured to run in SQL server. Both apps use the same aspnetdb database but have different application names.
The problem I have is:I have an Identical login for each app (same username, same password), but If I change profile information for that user in the development app, the changes are reflected in production app. This isn't what I want.
Is it possible to share a cache between multiple ASP.NET applications? The apps may reside on different servers. How can one achieve this requirement?
View 1 RepliesI would like to share the session variables between 2 applications. basically I have a website and in there I have 2 applications and want to share the session object betwen the two. Is there a way to set something in web.config to enable this?

View 6 RepliesI have an asp.net solution in which there are two web application projects (client website and admin website) and also a class liabrary project in the same solution . In the live production server, the admin web app is within the client app (eg: client site= [URL] and admin site=[URL]). A class (with static variables) in class liabrary is userd to cache data. My problem is that i cannot get the changes to the static cache by one web project reflected to the other (becoz, i think, they seem to load in seperate appdomains).
View 3 RepliesI have 2 applications App1 and App2 on same domain, both with Forms authentication, each using a different database instance for authentication.
First, I open a browser with application www.mydomain.com/App1 and log on.
After that, when I open another instance of the same browser with application www.mydomain.com/App2 and log on, first browser loses session and goes back to login page.
I need each application on same domain to have its own session so that both can stay logged on.
I have two different IIS applications within the same domain(let us say www.mydomain.com) , both of these applications use the same database instance(same connectionstring), now what I want is that both of applications can see each sessions variables , can SQL Server session state mode helps in this case? Did someone try that before? Is there any other way to share the session variables?
View 3 RepliesI got loads of website, that share one of two baseclasses. I need the two baseclasses to be able to share part of the same code. I dont want to have to duplicate the shared code per baseclass.
so.. I got a page.aspx that inherits the baseclass and that inhertis 'sub' baseclass that inherits the web.ui.page class. So far so good :-)
In my baseclass I got a Public (at the top of the class not in any method- not sure of the proper term) Varable that is constructed from a structure in the BO class.
it Public PageDetails AS CoreDomainSetupBO.GetStartUpDetails = {database method}
I need the pagedetails to be available in the sub baseclass but it cant be defined there as the page details value is defined differently in the different base classes.
I hope that makes sense, I need to sub base class to be able to use a property that is defined at baseclass level.
I am looking for general direction on the best practice here. I have a class that I want to share between two different forms in two projects that are associated. The two forms are in seperate projects but both projects load together as I have added the second project to the first. I also have a class that I want to share between these two projects which will cause me to add another project to this solution with will mean I will have three projects in my solution. My question is how do I best share this class?
I believe the only way to do this is to add the class in the reference in both of the form projects?... Is this correct ? I'd really like to just reference the class and inherit it in the source code without adding it as a reference but I am feeling that I can't do that. I am obviously pressed for time and working on other projects and a I am a experienced coder with only about 1 year of C# experience...
My MVC ASP.NET web application is split up like this:
Web Application Layer Views
[Code]....
Now, I have a view in the database called "EquipmentWithCableDetails", which contains additional useful information with the equipment details - so I create a class to model that view (in order to be able to read from it). In the code I have that works with that new class, I want to display the EquipmentDescription - but that property only exists on the Equipment class.
1) I have a question, many kind of applications / programs offer API's for integration.Is it possible to integrate any kind of application / program with any kind of application with the help of API ?i mean two completely different applications/programs with different database structure can still be integrated with each other with the help of API ?2) Where exactly is the API file stored ? i mean in order to integrate 2 applications i need to create an xml file ? and store it where ? or i have to do some modification in the code of my application in order to work with this api integration ? how it works..please guide me in a right direction....
3) Could anyone explain me how this API thing works ? i have been provided a PDF file by the application company that i need to integrate with my database based web application.now i have to make API connections in my code ? or how ?
I recently received a project that contains multiple web applications with no MVC structure. For starters I've created a library (DLL) that will contain the main Business Logic. The problem is with Caching - If I use the current web context cache object than I might end up with duplicate caching (as the web context will be different for every application).
I'm currently thinking about implementing a simple caching mechanism with a singleton pattern that will allow the different web sites (aka different application domains) to share their "caching wisdom". I'd like to know what is the best way to solve this problem.
I have a WPF Windows application with sqlite database which we distribute to our clients. The application consists of some database table which changes every month. eg. the application users a exchange rate table which is valid for one month.
What is the best approach to update the data in these table. note that the whole application is not changing but only the data in it changing, no change to structur of the database or table.
Imagine I have a class MyTestClass. And I need an instance of this Type throughout my whole web application.Now there are several possibilities to accomplish this.1. Make MyTestClass static, make it contain static methods only
Probably the most performant solution. I'm not feeling lucky about using static fields though. Thread safety? What if my static class contained a static System.Collections.Queue?
Even though I'm trying to implement exception handling in a multi-tiered Windows application, catching and throwing exceptions should be the same for Windows and Web (sans global.asax and web.config custom errors).
I have a webform with a texbox that displays exceptions. So my webform invokes a method in BusinessTier class which then invokes a method in DataTier class. How can I throw my DataTier method exception so it reaches my webform?
where to create the BLL and DAL and all classes in it can we place them in the App_code folder as it ll convert them into DLL Files or do we have to create a new class library project for each...
View 1 RepliesI see on the bottom of blog pages a sharing buttons (Twitter and Facebook), where if clicked the link behind (which is normally the blog page url) the fshare button takes the clicker to the blog site facebook page respectively.
How does one do this in asp.net 2 , does one one use the <%# %> in the url part of these share buttons, are there any examples of how this is done?
I've been worked with web services so far, and I'm interested in expanding my services to console applications as well so I started digging up with WCF but I'm conserned that I won't be able to use the HttpContext collection that I've been used to do with web services one important thing which is to generate a random value from HttpContext.Current.Request.ServerVariables["ALL_HTTP"] that I need to reckon if it's the same or at least near what machine that is calling my service. How can I overcome this problem?
I need to know what machine is calling to count the number of attempts to login into my system for example. So must do it inside of the svc code otherwise if I let the client inform what ip address or what computer he is using, anyone could forge this argument and surpass by another machine. May be I'm approaching this matter wrongly. And I should count the number of attempts per state session, but how is it done?
If there is a self contained web app, let's use the Screw Turn Wiki as an example, that utilizes the App_Data to store the MDF, is there any way another web app, living in the same domain, can also use that MDF?
Example IIS Setup:
http://wiki.domain.com | c:webwiki | port 80
http://www.domain.com | c:website | port 80
My WWW web app would like to pull some data from the WIKI app. Without moving the MDF to a full fledged SQL Server is there a way to do this? Also note, the WIKI app is an installed app so I don't have access to its source.
i want to maintain session data between two applications or domains [URL]. I have read on net about this, but many people pointing many different ways to do it, with people commenting +ve and -ve responses to all. Plus many are just providing theoretical answer, do this and that ,but no code at all. are these steps all that is required?
1) in web.config: <httpCookies domain=".[URL]"/>
2) store session data in sql DB as:(after preparing the db for storing sessions)
<sessionState mode="SQLServer" sqlConnectionString="Data Source=YourServer;
Integrated Security=True;database=MySessionDB" sqlCommandTimeout="30"
allowCustomSqlDatabase="true"/>
<machineKey decryption="AES" validation="SHA1" decryptionKey="..." validationKey="..." />
3)Am confused about this one: i want to set the domain for the session cookie like this
Response.Cookies["ASP.NET_SessionId"].Domain = ".[URL]";
But where should this code be written?
this entry: [URL]says: use System.Web.SessionState.SessionIDManager as a base class but the SaveSessionID method is not virtual so cannot be overridden. Options are: either explicitly re-implement the interface method or decorate SessionIDManager class and after calling SessionIDManager.SaveSessionID set Response.Cookies[SessionIdCookieName].Domain to our domain.
Only if the author had provided real code, step 3 would have been clear. Plus all this 3 steps enough to share session among the domains?
