I'm calling a 3rd party web service from our network and I receive following error: No connection could be made because the target machine actively refused it 111.111.222.545:443
View 8 RepliesBut the issue here is that I am using a post request trough an WCF app. This will work fine on my home PC call(web form - web app) - from the work PC call. It will not work from the WCF service I use that uses LOCAL IIS 7 or my work PC (that an app I created works fine through my local PC).
So I tried various IIS manipulations, made it iis express, made it visual studio IIS, made it local IIS, made it https, http, nada.
When debugging the code and it goes to the getrequest - from site line, it will break.
What is going on here? Is it the IIS? The wcf works flawlessly on about 20.000 lines of code but the post call to another vendor will break.
can anyone explain to me what is the error... im using c# .netNo connection could be made because the target machine actively refused it (ip address)code behind:
MailMessage mail = new MailMessage();
mail.To.Add("emailto");
mail.From = new MailAddress("emailfrom");
[code]...
{"No connection could be made because the target machine actively refused it
I get the above error...
No connection could be made because the target machine actively refused it 127.0.0.1:51273 when the project deploy in IIS. But it is fine running the project in localhost. How to fix the error?

View 1 RepliesI have a simple web app that queries a server based database. I have tested with both a simple MySQL table and Access tables. The problem is the same whatever 'backend database' that I use. When I run my web application under the VS 2008 debuger then all works fine. No problems with the code. I then publish my web app to either my local IIS or to a different PC's IIS on my network. I then get 'intermittnet' problems reading the data tables. The connection strings are fine. I get a connection. It is when I try and fill the tables that I get errors. The web app just seems to 'hang'.
If I publish to a different IIS on my network (on a different server) the I get the same problems. If I reboot the IIS machine then I seem to be able to get to my data for a while before the IIS seems to 'lock up' and I can't read data anymore. Is this an IIS/authentication/resource issue?
even i moved my project to my freind's pc and installed every thing correctly i still get this error
the login is made automatically by the name of mssql server connection ?
how is it , even i checked out my DB and found that ther's no users with such name ?
Something odd has started to happen when I create a web reference in VS2005 (the web service is on a network server). In the wizard I navigate to the correct url, but when the reference is created, the web.config key value has the machine name rather than the alias name I selected in the wizard. This causes a problem because of an SSL cert name mismatch.The network and server guys think I've done something in VS to cause this behavior while I believe something has changed in the environment.
Some Background: IIS is running in a cluster rather than a Farm configuration, and there is some failover mechanism in place. The server guys tell me that the key name value in the web.config file is the name of the active node in the cluster.
Provided wsdl from link below:
http://www.2shared.com/file/zfTUDRl3/poccrm.html
I've been given merely a wsdl above from client, without any further information given, to make a call using c# code but i added as web reference, used the codes below and the client side detected my request and they've returned us proper format xml too, but i cant retrieve it in the string array from the method returned. the "stringset" has became null instead of array[10]. Can anyone give a hint what kind of web service call is it, since it is not using the simple and classic way to invoke?
static void Main(string[] args)
{
//added web reference for wsdl as poccrm
string[] stringset = new string[10];
poccrm.poclib caller = new ConsoleApplication1.poccrm.poclib();
poccrm.SE1I2001 callerItem = new poccrm.SE1I2001();
callerItem.AcctNo = "0010241000007914";
callerItem.TransNo = "12345678901234567890";
callerItem.StartDate = "20-01-2010";
stringset = caller.SE1I2001(callerItem); //here i get null for stringset, but client received the request and returned us value
//same result even I use wsdl.exe converted it to a class file
/*
string[] stringset = new string[10];
poclib caller = new poclib();
SU1I1001 callerItem = new SU1I1001();
callerItem.AcctNo = "0010029004000370";
callerItem.transno = "12345678901234567890";
caller.end
stringset = caller.SU1I1001(callerItem);

I am doing a web project in asp.net. Now I am trying to keep each connection string for each user. And the user can decide which server he prefer. How to change this dynamically and where can I store this?. I happen heard about machine.config .Unfortunately i am not familiar with this. Can you just tell what it is and it's use.
View 3 RepliesI have a Windows Service I have developed in Visual Studio 2005 (C#).
It accesses a database using a connection string in machine.config.
On my Windows XP Pro 32bit (SP3) machine, it works correctly.
On my new Windows 7 Pro 64bit machine, it throws "object not set to an instance of an object" when it gets to the line where it's trying use the connection string.
This is the 'object' which is not set in Windows 7:
ConfigurationManager.ConnectionStrings["MyDatabase"].ConnectionString
The machine.config has the same connection string set up on both machines.
A .Net 2 website transferred to the Windows 7 machine has no problem accessing the same connection string.
I have tried a bunch of different permissions on the machine.config and its containing folders, and setting the service to log in as Admin, but I don't know exactly what permissions are required.

we are using WCF web service. My job is to create the client WCF service.
Sample 1
try
{
Serviceclient client = new Serviceclient();
client.GetOrders();
[code]...
Which the best place to close the connection. Is it in Server side or Client side?
I have a web service that calls another web service (not my design).The wrapper web service is our code the underlying web service is 3rd party.The issue is that when one of our apps calls the web service wrapper.. it opens a new connection to the underlying web service and that login time is around 10seconds! (3rd party issue)... the calls after the login are fast in testing.SO we are trying to have ONE login for all the calls to the underlying services. However our wrapper service is called one by one..I was thinking if there was a way to store the underlying web service connection in a cache (netbean?) I could reuse it for all web service connections to the 3rd party...
View 1 RepliesI need to connect to a WebService provided by someone else. This WS (all https) has three methods that are accessible without having logged on:
login, logoff, getVersion . All other methods require that the login-method has been called before. Nothing special unto this point. However, the docs state that I have to make sure that (quote):
"All method calls between login and logoff are to be carried out by means of the same persistent http-connection (key word: http persistent connections or http connection reuse"
I seem to be unable to figure out how that would work - all WS'es I ever utilized were either taking user/pwd combinations in each method call or the login-method returned something like a SessionID which was then used for each subsequent call to a given method (i.e. passed as a parameter). If I call the login-method and subsequently call any method that requires authentication, the call will fail with an exception telling me that I need to log in first.
I am working in ASp.net web application, where user will be asked to give interview.
View 3 RepliesI receive the following error, when trying to consume Wcf service:
"An existing connection was forcibly closed by the remote host". Consuming the service works fine when the host and the client are on the same machine. When I move the client to Hyper-V virtual machine (I didn't try it on a real computer) - it throws the error. Both firewalls are turned off Do you know what can cause such behaviour? Here are the details:
Both the client (hyper-v) and the service are on Windows server 2008 R2
Service url - http://wcftest/CalculatorService.svc (wcftest is the website and is mapped in the hosts file to localhost)
Service config:

Are there any configuration settings which I'm missing?
How do you secure a WCF web service when you are using the traditional "connection string in the web.config"?
I have added a WCF service to an application which uses a JQuery post and returns JSON. The request happens on the client side. The purpose of this service is to return search information while the person is typing text into a textbox.
It works well, but there is a problem because the application will be used by a number of people and I am maintaining a role based security within the applications MS SQL database. The connection string to the database is in the web.config file.
In order to run the JQuery call to the web service the user must have at least read access directly to the database. I want to allow the application to control the access, but removing all security to the WCF service opens the application up for external access by unauthorized users.
I'm having error:
The pipe endpoint 'net.pipe://127.0.0.1/TestService.svc' 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:
1st(Host)
[Code]....
2nd(client)
[Code]....
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 http://127.0.0.1/TestService.svc.
What am I doing wrong? Why do I receive this error?
