I thought I ask the more exprienced Silverlight users about what they think is the best way to embed Silverlight user controls into an ASP.NET page - in special regards to stablish an easy way of communication between the conrols.
I have heard about services, query strings, etc. but I'd like to find out what has worked for you the best so far...
I am planning a SaaS system, to be written in C#, ASP.NET using WCF that has two separate components:
On a static IP web server in the cloud will be a web app, common to all clients. Inside each client's office will be another app, installed on a server with IIS.
The site app will obviously be able to connect to the web services published on the web site. But here's the rub - I also want the web app to be able to initiate a connection to the site app... and the on-site server may not necessarily have a static IP. I can't control this, because we may have hundreds of clients at some point in the future, and we cannot limit our saleability by insisting that the customer has a server with fixed IP.
So, how to do this?
I could have the site apps "checking in" with the web every minute or so, to give the web app the possibility of responding with a "while you're here, do x,y,z..." but that seems very inelegant. Also, if we're talking about hundreds of clients, I don't want to be bombarding my web server with all these "hi there!" messages if they're not actually required.
I'm having a problem, which I haven't had with other projects, in setting up membership. I have set up a aspnetdb database using the asp.net confirguration tool. The database is in the app data folder and I can set up users and roles etc from the web site administration tool. However, trying to log in within the application, using the login control I get "Login attempt was not successful".
I have noted the following :-
1. On the home page of the Web site administration tool the application:/ shows no application where as normally it would show the name of the application.
2. Clicking the AspNetSqlProvider test button, I get the error "could not establish a connection to the database"
3. Although various lines have been added to the web config file, no connection string has been created to the aspnetdb file in the app data folder.
4. If you right click on the aspnetdb file within the solution explorer, there is an option of "include in project". Selecting this doesn't however solve the problem.
Currently I am functioning on a project (Winfroms). Where I can able to communicate with the USB device and send/read data from it using the WINUSB custom driver. This will work only in windows. Now currently the client want this in web whereas independent of OS (Linux, Mac, Windows). Accessing a driver from a client side to send/read data that too for different OS.

View 9 RepliesASP.NET 2.0 and COM Port Communication
I have a managed DLL which communicates with the devices attached on COM/Serial ports. The desktop Winforms application sends requests on ports and receives/stores data in memory. In Winforms app I have added a reference to DLL and I am using the methods. This works well. Now, there is a situation where I need to show this data from serial/com port on a web-page. And also users should be able to send requests to the ports using this DLL. I have made a web app in ASP.NET (2.0). Added a reference to the DLL. I am able to use this DLL, the DLL communicates on the COM upon button click on web-page and also the response is shown on web page. However I am not happy with the approach and strongly feel that this is a bad approach. Also the development server crashes after 3 -4 requests. What is the best approach in this scenario. If I use a windows service then how would my ASP.net app will communicate with the Weindows service.Or can this be easily done using WCF. I have not used WCF any time nor any of .net remoting technique.

View 4 RepliesI have run aspnet_regsql.exe beaucoup times and it creates the database aspnetdb.db. I have created it in my primary database connection and in the SQLExpress connection.
Then I open Visual Studio 2008 and run the ASP.net Web Site Configuration Tool. I click on Provider tab and select Select a single provider for all site management data. The provider shown is AspNetSqlProvider. A book that I'm reading says it should be aspnetdb.
When I click on the test link, I get the following message
Could not establish a connection to the database.
If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider.
In my book, it looks like the aspnetdb database should appear in the app_Data folder of my web site. What is supposed to put it there? Does it get moved from the SQL Server Data folder?
I've created an ASP.Net 4.0 web application. It uses Forms Authentication. I have an ASPNETDB.mdf file in my App_Data folder courtesy of SQLEXPRESS. I have appropriate settings in my web.config for connection strings and providers (since I know it will be asked for:
<add name="ApplicationServices" connectionString="data source=.SQLEXPRESS;Integrated Security=SSPI;
AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>).
I have roles and users setup. I have been running this with absolutely no problems in both my dev environment (i.e. Cassini) and on a "production" (not really, but a machine that was published to). And the "production" machine still has no problems.
So, everything has been working perfectly fine until early this afternoon and all of a sudden it all stopped. The only things I did from when it worked until it stopped was: I connected to and checked in all my code to a TFS server (2010) and then I updated namespaces all around. I have not made any changes to my web.config since it worked, nor to the database. I'm really not sure what happened. Oh, and the "production" machine never got the namespace updates. But, it did get a publish immediately before I uploaded everything into TFS.
It started with me getting a login failure in my app. I know the login is correct (it still works on the published system). So, I went into the Website Admin Tool and clicked onProvider Configuration -> Select a single provider... -> Click on Test next to AspNetSqlProvider (only option). I get back an error: "Could not establish a connection to the database." So, this tells me that for some reason, it can't see my database. All my roles and users still show up though in Security.
Since these two actions, I have wiped out all my code locally and refreshed from the first changeset in TFS. Still no workie. I still get the "Could not establish..." in WAT. Every post I can find online keeps talking about connectionStrings and database configuration (i.e. aspnet_regsql). However, since this was just working with no issues, I'm pretty sure none of these are my problem. Especially since I refreshed my code to an earlier "working" state (prior to namespace changes) to no effect.
I am not yet at the point that I'm willing to wipe my database and start over. Again, because this was working before. I have noticed and read several posts by Sukumar Raju among others (including his blog posts, one here) and none of them helped or were quite related to my specific issue. Good information, but not what I needed.
I'm sure something went offline somewhere and I can't see it. I did check to make sure that the SQLEXPRESS services (including Browser, etc.) were started. Even restarted them to no avail. I'm sure it has to be something simple and I'm just missing it somewhere.
I am having a domain name and web space (the web is running, its ASP.net 3.5). I am working on a project in which I need to connect 2 computers over the internet.
Is it possible to do that with a simple ASP.Net website? What other things I do need to do this?
EDIT
Actually I want to send the data from one computer to another in real time, I mean as we do chatting we exchange text to one another. The same thing I want to achieve.
Could not establish a connection to the database. If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider.
I don't know where to go next as this error message does't give many leads. I have already configured that database with the aspnet_regsql tool. In SQL Mngt. Studio I can see that the database aspnetdb has been created. I'm not sure where to go from here. The only connection string in my web.config file is the one for connecting to my content database.
I have hosted a webservice in my server and i need to access the same in a web aplication and smart device project . Added the same in both solutions its working fine in a webapplication. But in smart device project we added the web reference and while deploying we are getting an error
"Could not establish connection to network"
I have a .net web app hosting in IIS6 with Windows Authentication and anonymous access disabled. The web app is making connection to a SQL Server that is in the same domain, but on a different machine.
I want to have the IIS Worker process acount I_USR_... to be granted access to the SQL Server.
Will this work ?
(Is there a one to one trust ? Or should I make some extra effort to make the trust work ?)
(edit) On this page I read:
IUSR_ must be in the domain, and given proper access to the SQL Server; or, you must disable anonymous access on the site / application - which will allow IIS to pass the users' credentials to SQL Server. Not doing either of these things will result in an error.
Currently I'm learning on one of Joe Stagner video "SEC-009-CreateMembershipSchema" I followed exactly as told except for that Joe's is building the database in his JoeStagner server and not JoeStagnerSQLEXPRESS. But in my case I built my database in my MACHINENAMESQLEXPRESS. Another different thing is Joe's using SQL Management 2005 and I'm using the free version of SQL management 2008.
So I followed every step, inch by inch but when I tried to run a test on the AspNetSqlProvider, I'm getting this error Could not establish a connection to the database.
If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider.
here's the connection string I added in just like in Joe's video
<connectionStrings>
<remove name="LocalSqlServer" />
<add name="LocalSqlServer" connectionString="data source=.SQLEXPRESS;DataBase=AspNetServicesDB;Uid=AspNetServicesUser;Pwd=password"/>
</connectionStrings>

View 1 RepliesSo I am working on a project in ASP.NET MVC 2 with C#.I have a View with a file upload but this is a flash component (.swf).The result of the file upload (the storing of the file and processing of data in the database) is done in a HTTPHandler.I would like the HTTPHandler to send information to my active controller.
Is there a way to get the controller that was used to load the view? I'm having problems finding information about it online.
I'm running an ASP.NET WebService on IIS 6.0 that shows a lot of HTTP 500 (probably just exceptions from the WebService) inside the log at %systemroot%System32LogFilesW3SVC1 on a customers site.
Is it possible to log the content of those HTTP responses and there requests without modifying the WebService using IIS or a plug-in for IIS?
I thought of using Wireshark or Fiddler to sniff on the HTTP traffic but I would prefer to just turn on an option inside IIS to make him log the communication (this should not be to hard since it is logging the requested URLs anyway)
I have an ASP.NET app running on a webserver. A third party is created another app in PHP which needs to send data to my app for processing. Initially it was assumed that the PHP app would be deployed elsewhere so we agreed that the communication would occur over the internet via HTTP (over SSL). My app would simply use a generic handler (ashx) file to recieve the data and send confirmation back.
Now it seems that the PHP app might be deployed on the same machine as my app. I like the fact that using HTTP (as opposed to say direct database access), the PHP app needs to know nothing at all about how my app works. But using the public internet seems silly for communication between two apps on the same machine. If the PHP app simply used a localhost address, would this ensure that all the data stays within the machine? Is there a better way to do this?
I have two web parts WebPart1 has a tree control1)WebPart2 gets displayed when a node in a tree is clicked.2)User can enter a text in web part 2 and click ok button then Web part1 has to be refreshed and the new node should get displayed In step 1 WebPart1 is Provider and WebPart2 is consumer.In Step2 its vice versa. Is it possible to swap this using the provider consumer?
View 1 RepliesI am create an iPhone app that needs to talk to a Windows C# app. The app will run as either a Service or Form Application.
What would be the best way to accomplish this? Ideally exposing a service-type architecture would be best as I don't need a stateful connection (stateless is fine in this case).
Can a WCF service hosted by my app using a form of TCP binding be consumed by my iPhone? Or can an app host using httpBinding without the aid of IIS or some other web server?
To guarantee optimal performance, aspnet_isapi uses asynchronous named pipes to forward requests to the worker process and to get responses. On the other hand, the worker process exploits synchronous pipes when it needs to query for information about the IIS environment (that is, server variables).
Does the worker process always uses "synchronous" named pipes? (Response to aspnet_isapi.dll would be asynchronous too, right?) Can the worker process talk directly to IIS or does it have to send a synchronous request to aspnet_isapi.dll to inquire about IIS environment etc.?
i built a web based task manager / scheduler using vb.net
i need to add a small communication part to it to allow users to send messages to each other.
below is my concept design. the question is: is this the correct way of building a simple communicator or do you have better ideas?
I've a project in C which acts as a server and accepts socket communication. The server project has multiple C files is an exe which accepts messages from the client program and responds accordingly. I've to write a Client program in C# which should open a socket communication and send a series of messages depending on the result of previous message sent.
Is it possible to send a message in such a way that it will call a function in one of the C file in the server project?
I am working on a project where I have to design a front end(on C#) and have to display the data coming from PLC.

2. What function I have to used for Serial communication.
3. What .dll file I have to add in my project.
