have a web service that I'm trying to consume from a console app through http post. I receive a 500 exception error from the xmlstring parm being passed to the web service. Add the following to web.config of the web service. Although it is not working in debug in vs 2008 as well.

My web service uses .Net Framework 2.0. An e-learning application reads and updates an Access database in the web service via Http Post commands. I test the e-learning application and the web service using the version of IIS 7 that came with Windows Vista. I run IIS using localhost in my browser.
All works well. But a friend is having trouble running the same test with my files on her IIS 6 server. So I'm developing a checklist of issues in setting up an IIS 6 server to run a web service. I plan to include all possible causes of problems including permissions, accounts that are needed, etc. Are there resources to which I can go for this checklist?
we need to expose a web service to the 3rd party vendor which can only call using POST protocol, NOT SOAP.So my question, is it better to build a web service or just simply .aspx page?Also is there any best practice documentation on this.
View 4 RepliesI'm trying to upload a file to an ASP 2.0 web service through HTTP 1.1 POST from a client-side application. If my web service function is declared as
<WebMethod()>
Public Function UploadFile(ByVal file as Byte(), ByVal fileName as String) as String
...
The test form says the request should take this form:
POST address_of_service HTTP/1.1
Host: <host>
Content-Type: application/x-www-form-urlencoded
Content-Length: length
file=string&file=string&fileName=string
How do I get my binary file data into that form? I've tried just converting the file data to a string and putting it in the body (file=<string_data_here>) but I get HTTP 500 errors back, complaining about not being able to convert it to System.Byte. I've got HTTP POST working fine elsewhere in my application with plain string parameters. Also, out of curiosity, why is it showing the file parameter twice?
I am currently writing a C# web service which has several methods, one of which has to receive HTTP POST requests. The first thing i have done is alter the web.config file in the web service project as below.
[code]....
But when i run this i get "The remote server returned an error: (500) Internal Server Error". If i remove the parameter, by removing the stringbuilder and byte code, as well as having no parameter in the web service, it works. So it is obviously a problem with the parameters. I actually want to send more data, and was using a string[] parameter in the web service, but this also failed.
cant read http custome header "MSISDN" from my web service ... same code works on regular asp.net page. Can anyone shade a light on that subject ?

Maybe fiddler can be set up to allow this, I am not sure :-s If anyone knows, can you explain, or if anyone has used a tool on their local machine that can catch HTTP request/responses from the above code?
I am trying to call webservice from my web application. The web application had integrated windows authentication. I've written custome principal class to do authorization. But when I give call to my web service with default credentials it gives me 'the request failed with http status 401 unauthorized.' error.
When I give call to my local webservice it is running fine (It also has integrated windows authentication) But when I add reference of same web service from QA server I am getting this error. Not sure what is happening. I also tried
WS.PreAuthenticate = false;
WS.Credentials = System.Net.CredentialCache.DefaultCredentials;
I can't seem to call a web service method from Ajax with both POST and GET.
Initially only the POST would work and GET would causes this error:
{"Message":"An attempt was made to call the method u0027getDatau0027 using a GET request, which is not allowed.","StackTrace":" at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext
context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}
I fixed that by adding this attribute: [ScriptMethod(UseHttpGet=true)] but now GET causes this error:
[code]....
So is it true that you can only use either POST or GET and not both from Ajax?
How may I post arbitrary data to a REST WCF webservice? I mean, wihout use contracts.

If I punch this into a web browser I can access it fine, however, if I create a web reference using this URL in Visual Studio (2005) it can create the web reference fine and it builds ok. But whenever I call a web method on this service instance I get a HTTP 404 page not found Exception.
Is there any properties I need to set on the web service object to get this to work? I'm confused as to why it's not working.
I am trying to post data from vb.net application to web service asmx that is located on server! For posting data from vb.net application I am using this code:
Public Function Post(ByVal url As String, ByVal data As String) As String
Dim vystup As String = Nothing
Try
'Our postvars
Dim buffer As Byte() = Encoding.ASCII.GetBytes(data)
'Initialisation, we use localhost, change if appliable
Dim WebReq As HttpWebRequest = DirectCast(WebRequest.Create(url), HttpWebRequest)
'Our method is post, otherwise the buffer (postvars) would be useless
WebReq.Method = "POST"
'We use form contentType, for the postvars.
WebReq.ContentType = "application/x-www-form-urlencoded"
'The length of the buffer (postvars) is used as contentlength.
WebReq.ContentLength = buffer.Length
'We open a stream for writing the postvars
Dim PostData As Stream = WebReq.GetRequestStream()
'Now we write, and afterwards, we close. Closing is always important!
PostData.Write(buffer, 0, buffer.Length)
PostData.Close()
'Get the response handle, we have no true response yet!
Dim WebResp As HttpWebResponse = DirectCast(WebReq.GetResponse(), HttpWebResponse)
'Let's show some information about the response
Console.WriteLine(WebResp.StatusCode)
Console.WriteLine(WebResp.Server)
'Now, we read the response (the string), and output it.
Dim Answer As Stream = WebResp.GetResponseStream()
Dim _Answer As New StreamReader(Answer)
'Congratulations, you just requested your first POST page, you
'can now start logging into most login forms, with your application
'Or other examples.
vystup = _Answer.ReadToEnd()
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
Return vystup.Trim() & vbLf
End Function

No connection could be made because the target machine actively refused it 127.0.0.1:8000
Metadata contains a reference that cannot be resolved: 'http://localhost:8000/Tasks'.

If the service is defined in the current solution, try building the solution and adding the service reference again.

I am new to WCF, I was using web service asmx before. I have trouble on making my wcf JSON ajax service work through http like asmx.Could you help me see what wrong in my code?My WCF services are defined in my website application folder. My aim is to call this service in my aspx page java-script code and return complex object back as JSON to my javascript. I have no problem on doing this through classic asmx web service.
When I try to test it through my browser by type this in the URL , URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc/GetAll. it return "Method not allowed."
But if I type just this URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc, it return this:
WCFCompanyService Service
You have created a service.To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax:
svcutil.exe URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc?wsdl
This will generate a configuration file and a code file that contains the client class. Add the two files to your client application and use the generated client class to call the Service. For example:
C#
class Test { static void Main() { HelloClient client = new HelloClient();

View 2 RepliesA customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.
I have a .net app developed in .net 4.0 version. And I implemented an asmx web service in this. Now I want to call one of the webservice method in another classis ASP application java script function.
