WCF / ASMX :: The Pipe Endpoint 'net.pipe://' Could Not Be Found On Local Machine

Nov 15, 2010

I'm having error:

The pipe endpoint 'net.pipe://' could not be found on your local machine.

I have 2 web applications deployed in IIS7:

1st - host(application hosts WCF service TestService.svc, 2nd application should be able to acces this service)

2nd - client(application should use service hosted in 1st application)

I have configured net.pipe binding.

Here web.config files:





I've already done with adding net.pipe biding for host application. net.pipe protocol also enabled for the host application.

I can see the service page when I'm opening

What am I doing wrong? Why do I receive this error?

Security :: Restrict Login Access To Website From Specific Machine?

Nov 1, 2010

I need to restrict access to my website by physical PC. When a user signs up I want to be able to restrict access to one machine for that account so it cannot be shared round, if, for example, somebody else in the same office wanted to access the system on their PC they would need a seperate sign in.

I have done some investigation and I "think" the only way is installing an ActiveX component (which isn't an issue that is restricts to IE only) and then read the users MAC address. Am I trying to over complicate things or is that the only way? I realise that MACS can be spoofed but this is not much of an issue.

Configuration :: Cannot Open A Word Document From Web Server Machine

Mar 26, 2010

I wrote an web form application in C# to open Office Word 2007 documents from the application. This worked perfectly testing in my development environment. But after deploying my application to web server, the documents do not open and I get the following error retrieving the com class factory for component with clsid failed due to the following error: 80040154

It looks like it may be because Office Word 2007 is not installed on the web server box. Would installing it on the web server be the solution, or is this a bad idea. If it is not the solution, then would is an alternative way to do this.

Getting Appending Html In Csv File (open In Excel) After Download From Server To Local Machine

Dec 9, 2010

I have created a CSV file on the server and want to send it to the user using the following code:

Dim strPhysicalPath As String
strPhysicalPath = Server.MapPath( "CSV/" & PathVirtual)
Dim objFileInfo As System.IO.FileInfo = New System.IO.FileInfo(strPhysicalPath)
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader("Content-Disposition", "attachment; filename=" & objFileInfo.Name)
Response.AddHeader("Content-Length", objFileInfo.Length.ToString())

This seems to work fine except when the downloaded file is viewed in Excell the html code behind the page from which it came is also appended to the file. Does anyone have any idea why it does this?

How To Get Website To Allow The Pipe Character In The URL

Feb 1, 2010

This website [URL] does not accept the pipe character | in the URL

This works [URL]

but this doesn't


It looks like the pipe is an issue as



I need to stop this because a third party called Omniture needs to access this website automatically with the | in the URL. I cannot ask them to encode the | as they are a big company. They say there is some way to allow the | but I am not sure how.

Shared Memory Provider, Error: 0 - No Process Is On The Other End Of The Pipe?

May 17, 2010

I'm tearing my hair out here - I'm building a .NET web application at the moment and every time I either want to access the database/build a page or create a new datasource I get the following error:A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)I also get it in SQL Server Management Studio 2008 quite a lot too. I know what you're thinking - search the web for the error, read what the nice people have to say. Only I've spent the last week or so doing this, and I'm no closer to resolving this.

C# - IIS 7.5 Configuring Website To Support Http - Net.pipe To Invoke WCF Service?

Nov 11, 2010

In IIS 7.5 i configured my asp.net website for "http,net.pipe" in "Enable protocols".


net.pipe configuration is done to call another module within the website (SOA). Every thing worked fine with simple asp.net & net.pipe service invocation calling other module. But When i try to call RIA service from silverlight 4 i get the following error

The provided URI scheme 'net.pipe' is invalid; expected 'http'.
Parameter name: context.ListenUriBaseAddress

How can i configure my website to work in http & net.pipe configuration ?

WCF / ASMX :: Access Error Connecting To Net.pipe Endpoint In WAS Hosting

Jul 22, 2010

I have a WCF service hosted on win 2008 server. I'm using WAS to expose a named pipe endpoint on the service and have a client website that consumes the service. When i hit the website from a remote machine i get the following error:The pipe name could not be obtained for the pipe URI: Access is denied. (5, 0x5)Now if i hit the website ON THE SERVER it's being hosted from, using localhost in the url, it works fine. Clearly there is something i don't understand about what the named pipe endpoint is looking for. I tried running a trace from my service, but there is no output because the call doesn't even get to the service.

Viewing File Using .net / To Copy/download File To Local User Machine And To Open

Nov 16, 2010

In our application, we allow user to upload documents which can be PDF, Doc, XLS, TXT. Uploaded documents will be saved on web server. We need to display link for each document user uploaded and when user click on that link, it should open relevant document. it is expected to have required software to open relevant documents.

To upload document, we use saveAs method of FileUpload control and it works absolutely fine.Now, how to view it?I believe, i need to copy/download file to local user machine and need to open it using Process.Start.For that i need to find user local temp directory. if i put path.GetTempPath(), it gives me web server directory and copy file there.

sPath + dataReader["url"].ToString(),
Path.GetTempPath() + dataReader["url"].ToString(),

I basically want to transfer a file from the client to the file storage server without actual login to the server so that the client cannot access the storage location on the server directly. I can do this only if i manually login to the storage server through windows login. I dont want to do that. This is a Web-Based Application.

filePath = FileUpload1.FileName;
WebClient client = new WebClient();
NetworkCredential nc = new NetworkCredential(uName, password);

Does Server.MapPath Behaves Differently In Local Machine And Server Machine

Jul 1, 2010

I have had a real nightmare with Server.MapPath(). When I call Server.MapPath("~") in my application that is running in ASP.NET Development Server it returns root directory that ends in a back slash like f:projectsapp1, but I call it in published version, installed in IIS, it returns root directory without any back slash like c:inetpubwwwrootapp1.

string mainRoot = HttpContext.Current.Server.MapPath("~");
DirectoryInfo di = new DirectoryInfo(mainRoot);
//added to solve this problem with Server.MapPath
if (!mainRoot.EndsWith(@""))
mainRoot += @"";
FileInfo[] files = di.GetFiles("*.aspx");
foreach (FileInfo item in files)
string path = item.FullName.Replace(mainRoot, "~/").Replace(@"", "/");
//do more here

Instantiating A Dynamically Named Class?

Jan 21, 2010

I have a C# web page that allows the user to select an object from a DropDownList. Each object in the list has its own class. On the user making a selection information appears on the page that is generated from its respective class.

How do I instantiate a class depending on the users selection? I could use a switch statement that would instantiate anyone of the classes pending the dopdownlist.selecteItem value, however I was hoping to avoid that.

Error - The Specified Named Connection Is Either Not Found In The Configuration...

Oct 5, 2010

I have a solution in Visual Studio 2008 with 3 projects. One Web Application and 2 class libraries. The entity framework model is in a class library and the start project is the web application.

I used to have this problem:

"The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid."

I fixed it copying the connection string from the App.config of the class library where the entity model is located to the web.config of my web application (start project).

I found that workaround posted here:


how can i avoid using the connection string from the web.config and use the one from the app.config where the entity model is located?
