Call specific web service method by matching string value to method name?

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :.NET Framework
I am getting a value in string format.  Then, I call a web service and try to dynamically call the method that corresponds to the string's value.  It doesn't work.  Any ideas?              Dim methodname As String = "getquotes"                 Dim track As localhost.Tracker = New localhost.Tracker()                 'the below line is where it fails                 track.methodname(parameter)

Parameter names ending with "specified" added to web service method call

Hello,I am new to WCF. I created a wcf web service and the generated web method exposed by wcf has some additional boolean parameters with names that end with "Specified".I am trying to understand why are these additional parameters necessary and how to get rid of them. Thanks!David

Spike in time requierd for method call in communicating with WCF Service


Here is my environment:

WCF Service hosted in Windows Service - all the methods in WCF Service are just skeletons; they doesn't do ANYTHING right now, for example
bool DoSomething() {
   return true;
WCF Client - WCF custom client developed by using files generated using svcutil (SDK 6A)
For Service contract - nettcpbinding
For MEX - wsHttpBinding

Both service and client  are/will be on the SAME machine

When I call methods from WCF Client in a tight loop (I am testing with 10,000 calls), for most calls time taken is 0 ms. But, after every 15/20 calls, it takes around 15-20 ms. And since service isn't doing anything, my guess is that it is time required _just_ for method call/communication.

I have also done this for WCFWindowsServiceSample example and it has same issue.

When I was using wsHttpBinding for service contract frequency of spike in method call time was much more as expected.

I am using System.Environment.Tickcount and although it may not be very accurate in determining CPU time, I am interested in total time taken so it should be okay (?)

Has anyone come across this issue? And is there a resolution to it?

If no one has come across this issue, do you have any thoughts on why and how it can be resolved?<

Call a web method in Javascript


Hi All,

I am first time working on web service and Javascript and trying to call a Web Method (web service) on a button click in Javascript.

What I want to achieve is as followed: When the button is clicked, call the web method, get the return URL value and store it to a session variable, the redirect the page to another page. However, this works only when the internet traffic is fast, it give me error when internet is slow as the Javascript is executed much faster than the web service. Is there any way to handle this?  Would be much appreciated for your help! Cheers.

Code as below:


function emailButton_onClick()


function getCurrentMapURL(getCurrentMapURLOnSuccess)
var proxy_url = 'WebService/GPSWebService.asmx/GetCurrentMap';

var response = map.print([proxy_url]);



function getCurrentMapURLOnSuccess()
emailAddress = document.getElementById('txtEmailAddress').value;

if(emailAddress != null)
alert('Do you want to send report

Cash Drawer - Method Open threw an exception - Windows Service

Hi All, I'm getting the following exception while calling Open method of Cash Drawer object. Method Open threw an exception.  Could not read the device name key's default value, or could not convert the Programmatic ID it holds into a valid Class ID. Code:   class Class1 { CashDrawer _uniCashDrawer1 = null; DeviceInfo cashDrawerDevice1 = null; PosExplorer posExplorer = new Microsoft.PointOfService.PosExplorer();   public void ClaimCashDrawer() { cashDrawerDevice1 = posExplorer.GetDevice("CashDrawer", "testDrawer"); if (cashDrawerDevice1 != null) { _uniCashDrawer1 = posExplorer.CreateInstance(cashDrawerDevice1) as CashDrawer; if (_uniCashDrawer1 != null) { _uniCashDrawer1.StatusUpdateEvent += new StatusUpdateEventHandler(UniCashDrawer1_StatusUpdateEvent); _uniCashDrawer1.Open(); _uniCashDrawer1.Claim(0); _uniCashDrawer1.DeviceEnabled = true; } } } }   Tha above code works fine if you put the code in WindowsApplication in all POS systems. The same is working if you put the code in Windows Service in all other POS systems. The same is not working if you put the code in Windows Service in Aures Galeo POS systems.  Thanks in advance.

How to set and map a Method in the Service file with endpoint elements and binding elements

Hi all, I have created a service file like OSService.svc in that i have two methods like one is FileUpload and FileDownload for e.g :- [WebInvoke(UriTemplate = "/fileupload/{fileName}" , Method = "POST" )]         [OperationContract]         void FileUpload(string fileName, Stream fileContents); same as Filedownload also. People you may know these methods are inside the interface of service file what you are using i'e i have created a interface as IOSService.cs. So, what i need now is i want to write separate endpoint for FileUpload and Filedownload.Because i want to set separate value for receiveTimeout  and openTimeout for the Fileupload and FileDownload process in binding section in the web.config file itself. The below code was i'm using right now but still i'm not able to the set separate value of endpoint elements in the bindings. EndPoint Section:- <endpoint name = "endPoint1"  address  = "localhost:8000/OSService.svc/" bindingConfiguration = "TransactionalTCP"   binding  = "netTcpBinding"          contract = "IOSService"/> Binding Section:-  <binding name = "TransactionalTCP"  transactionFlow = "true"   /&

WCF Basic Http Binding - Two server requests per method call

We have a service that uses BasicHttpBinding/Transport Security/Windows Authentication and is hosted in IIS. I have created a unit-test application in VSTS and whenever we test a WCF method, Fiddler records two calls. 1st call - No authorization token is sent. The WCF service returns a 401 error - Unauthorized: Access is denied. Http headers as sent in the request given below. POST http://localhost/AccountScreen.svc HTTP/1.1 Content-Type: text/xml; charset=utf-8 SOAPAction: "IAccountScreen/RetrieveAccountDetails" Host: localhost Content-Length: 243 Expect: 100-continue Connection: Keep-Alive 2nd call - Authorization token is sent and the WCF service returns the expected response. POST http://localhost/AccountScreen.svc HTTP/1.1 Content-Type: text/xml; charset=utf-8 SOAPAction: "IAccountScreen/RetrieveAccountDetails" Authorization: Negotiate Host: localhost Content-Length: 243 Expect: 100-continue I am not able to figure out why there are two calls made to the server in the first place and what is the significance of the first call. Any thoughts?
