AJAX :: Accessing A WCF Service Application From A Web Application?
Feb 10, 2010
I have a VS2K8 solution with a web app and a WCF Service App. In my web app I've added the service reference and can get to the service in the service app from code behind:
WebTest.ServiceReference1.Service1Client prox = new
WebTest.ServiceReference1.Service1Client("WSHttpBinding_IService1");
fromStandAlone.InnerHtml = prox.GetData(9);
prox.Close();
how to add an AJAX Enabled WCF service to the service app and how to access it from the web app?

I have some common dlls that are referenced by both a windows service application and a asp.net web application. I don't want to make separate copies of the dlls and I also don't want to put those dlls into GAC. I try to put that service application under the same root folder as the web application so that they can share the same bin folder. I am not quite sure if this will cause any problems? I did find the web application had random session timeout, but not very often. Not sure if it was caused by the shared dlls.
I am using VS2008 pro to develop my web application. my project target framework is 3.5. I can add web service (.asmx) to it. But there is no .svc for me to add, do I need to install WCF REST Starter Kit? (but it is only in Preview 2)Or should I add an WCF service project to my solution?
I've created web site in c:website folder using visual studio 2010. Then, I've created web site in IIS 7.5 that maps to that folder. However when I access Default.aspx page and request to css is issued like
I have to Pc, A is Server and B is client ,On server machine windows server2003 And iis is installed.i have developed asp.net application on server machine and its is executing perfectly on server like [URL]
but this page is not accessing on client Pc (B)
how can i access this page or Application on pc B(client).
I have an aspx page and I want to access an application on the client after seeking user permission. Both the windows application and the website are to be made in VB.NET.
EDIT: Here is the problem. From my .aspx webpage in vb.net, a visitor clicks on a link on my site, and if my winform is not already loaded on their desktop, it is then loaded with the users permission. This application should auto-load on the user's site at boot up time and always be in the background running. Make it an extremely thin client, taking the least cpu and bandwidth from the user, and running as a silent background process until needed.
Whenever the user visits one of my many websites, IN ANY BROWSER, somehow - the app running in the background communicates with the .aspx on one of my sites, and exchanges a silent username password identifying client winform app to the online .aspx app on my website.
Then the .aspx on my site PASSES a url such as "www.somewebsite.com" to the app running in the background, the background app then does a http request from the client's computer, not from my .aspx server, so the client's cookies and ip are visible to "www.somewebsite.com" server. The client collects the html for that page, stores it as a string, and also saves the ascii of that webpage as another string.
Both strings then are PASSED BACK to my .aspx website that the client is visiting, and the .aspx app then stores these results in a database.
i am using windows server 2003 and 2008 am about to install a web application on a server that is connected to other computers using simple wired network i.e. no active directory, no domain controller etc..
my question is:
is there a way to prevent mac addresses outside my specified list from accessing my application ? should it be through IIS or Web.config or should i put certain code in the page load events.another concern: if i use an SSL to secure my application, is it enough along with a reputable anti virus to prevent a virus to access my server through any network computer using my web application

I have no problem accessing these variables form .ascx.cs or .aspx.cs file -- ie. files that are part of the Web content. However, I can't seem to access 'Application' from basic class objects (ie. standalone .cs files). I read somewhere to use a slight variations in .cs files, as follows, but it always comes throws an exception when in use:
Then I have prepared a model,controller,view for accessing and displaying the data. I am using LINQ o get the data from database but getting the exception:" A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)" I have also installed the MYSQL connector. provide me the solution to access the data using MYSQL and LINQ in MVC application
I have an asp.net 2.0 web application that will run on the same web servers as SharePoint Server 2007. The application should run in its own App Pool (IIS 6.0). The Web Application needs to call the SharePoint Object model API.
Is there a resource that explains the required configuration / security settings and other considerations? It is possible that I need to make some settings in SharePoint Admin Console itself; aswell as config files. Script files might need to be located in a specific location in order to be accessible. Assemblies may need to be signed.
I can only get partial success running my Web application. But only if it is deployed to a Virtual Directory that resides under the SharePoint Website (in IIS & File system). Even with this setup, I JQuery / Javascript throw errors when accessed (object null); and also images not loading.
I have made some changes to the Web applicaton web.config file which have allowed me to run the application albeit the above mentioned issues with scripts and images (Virtual directory properties also set to allow scripts and executables to run). Ajax functionality appears to work OK.
I've got a webapplication and inside this webapplication I have a webservice. An external program is going to use this webservice in the future, but for now that is not the problem. this webservice is also called from inside the webapplication. this is where the problem starts.
I keep getting this error:
The remote server returned an error: (401) Unauthorized.
I tried with imporsonate= true, but it didn't work
[Code]....
the webservice is called like this:
[Code]....
I hope some one can point me into the right direction.
I have created an application directory in IIS and specified its physical location in my harddrive. im trying to create a new Http-based website in Visual Studio 2008 but im unable to assign it to that application directory because in the "choose a location" dialog I cant view that application directory under my default web site directory. can someone tell me why? is it because visual studio doesnt have permission to access it. if that is the case how can I edit the permissions of that application directory in IIS so I can allow visual studio to have access to it?
We have an issue with an internal application, where accessing it from LAN (private n/w) works fine, while access from external n/w throws up erratic behavior.
The Current System :
an aspx page (asp version 1.0) hosted on the IIS server (6.1). The front end is a vb form that connects to a sql 2000 database.
Users' credentials authorized using NTLM security.
Access from an external n/w - a reverse proxy configured with an ISA server 2006 to authenticate credentials.
Domain Controller - Windows Server 2008 R2 x64
The issue when accessed from external n/w :
everytime an entry from a drop-down is selected from an Ajax enabled control, instead of the fields populating, the page gets refreshed and the content of the box are cleared.
Also, clicking on other items that normally hyperlink to other pages, results in nothing happening.
Upon investigation, we realized that :
Everytime it fails, a string - "&AuthResend" followed by an alpha numeric string is attached, which attempts to authenticate the user's credentials everytime a request is made to the server.
ISA error logs yielded the following error msg :
"12210 Internet Server API ( ISAPI ) has finished handling the request. Contact your system administrator. "
This behavior is inconsistent except when accessed from Google Chrome, where it fails each time.
We have applied all the recommended hot fixes from Microsoft's KB pages.
I wish to acces my database using MSSMS at the same time that I am running my web application. When I tried to access my database with MSSMS I get the following error:Failed to retrieve data for this request (Microsoft.SqlServer. Management.SDk.Sfc)Additional Information:Unable to open the physical file "C:inetpubwwwrootmyappApp_Dataaspnetdb.mdf".Operationg system error 32: "32(The process cannot access the file because it is being used by another process)". (Microsoft SQL Server, Error:5120).What can I do to being able to view my database with MSSMS at the same time?
Can anyone explain why the following happens:My ASP.NET application requires access to Application event log.When I access web application initially, it returns "Security" exception (which is expected, as I haven't granted permissions to write to Application event log yet). Then I give read/write permissions to IIS_IUSRS group on the following registry key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetserviceseventlog. As a result of this action my web application starts working.Now I remove those permissions I've granted to IIS_IUSRS group. But my web application keeps working (although I'd expect "Security" exception raised again)So, why web application keeps working, although permissions to write to Application loghave been removed?
While running an app from the server where it is deployed the website works fine, however when trying to access it from a different machine(placed in same network), using the same credentials, it shows that I am not an authenticated user.
