WCF / ASMX :: Consuming Web Service W/ WSE 2 -or- 3?
Jun 14, 2010I'm taking over a project for a former co-worker. We're consuming a web service which requires authentication. The former co-worker was unable to call the service using WCF. I'm mostly unfamiliar with web services but was also unable to get it to authenticate.Upon speaking w/ the original developer, I was told that I'd have to build a project in VS 2005 in order to consume the service and that WSE 3 would have to be used, instead of WCF. He has some code that did indeed build and run on his PC, while he was here. I'm now unable to get it to build.
I'm running VS 2005 on XP and have WSE 3.0 installed and enabled on the project, which is a C# class library. I successfully made a Web Reference to the service and generated a proxy. In trying to test it, the first few lines of my code look like this:
[Code]....
...problem is, it says that the proxy that was generated does not have RequestSoapContext!

WCF / ASMX :: Consuming A PHP Service?
Aug 24, 2010I'm working with an outside company to impletement their API into our program. Most of their member functions working pretty solid. I get to the one function where I have to pass an associated array to it and this is where it blows up. I create a hash table or namevaluecollection and of course I will get the error(The type System.Collections.Hashtable is not supported because it implements IDictionary.), which can't be serialized.
Is there an easy way to pass this associated array to them? I don't think their api is very flexible, but they seem to think so.

Consuming An Array From A Webservice?
Mar 18, 2010I am trying to consume an array of strings from a webservice that I wrote. I keep getting the error: "System.NullReferenceException: Object reference not set to an instance of an object."
I know I am doing some thing wrong at an extremely basic level, but it's not coming to me.
I have tried adding New but get the error that you can't declare arrays with New
Here is the dummed down webservice method:<WebMethod( _
Description:="Testing ")> _
Public Function TestArray(ByVal Address1 As String, ByVal zip As String) As String()
Dim strTest(4) As String
strTest(0) = "It's"
strTest(1) = "a"
strTest(2) = "great"
strTest(3) = "day"
Return strTest
End Function
<--Here is the call that generates the null reference error-->
Private Sub FindAddress()
Dim svc As ws.Service
Dim strAddresses() As String
strAddresses = svc.TestArray(txtAddress.Text, txtZip.Text)
End Sub
Consuming A WSE-enabled Web Service In A 2.0 Web Site?
Jan 25, 2011I'm trying to consume a WSE enabled Web Service from an ASP.NET Web Site.I've installed WSE 3.0, used the config tool to add WSE info to my web.config and then done an Add Web Reference.I believe that the problem may be that this is a Web SITE, not a Web APPLICATION. As such, the proxy class is generated at runtime, perhaps not adding the WSE magic.I can access the proxy class from metadata, and it's of typeSystem.Web.Services.Protocols.SoapHttpClientProtocol, which as far as I can tell doesn't have any WSE functionality.I realize that this is all old technology, but I don't get to decide what the servers run :(

Architecture :: Consuming Excel Files For WF 4.0?
Dec 6, 2010Here's what I want to do, however I'm not sure of the best place for Excel. Excel files are sent via e-mail from various sources, from each source, they are sent in different versions of Excel and different information layouts, though from each source they are consistent.
Overview.
I want to give the user a front end to enable them to place the excel files into a drop zone and specify which files have come from which source. I then want to pass the file names and source origin to a workflow service. Based on this info the workflow service will then take 1..n workflow routes based on the source with the ultimate aim that data will be placed into an SQLServer 2005 DB or if the Excel lines cannot be processed, then output for the user to see with a reason. Because this is quite a complex task, I'm taking each source in turn.
Initial Problem.
My first set of Excel files come in 4 seperate files. I need to first merge the data in the Excel sheets to make 1 File for Processing. Some of the rows in the spreadsheets can be merged into a single line under certain conditions which will make the business logic much easier further on. So, first off After the user has dropped the Excel files into the drop zone I need to open the spreadsheets and merge them. I then need to feed each line to a 'rules' engine to determine the data and business logic that needs to be processed before updating the DB. So I thought I'd use a Workflow service for this since there will be no reason not to work on multiple sources at the same time as I progress through the development of the program. The problem I have is that unless I download the CP1 for workflow I cannot use this directly (so it appears) for working with Excel. So I was looking at using possibly WCF as the 'feed' to the workflow service, but can I use WCF to do the possible long running process of merging the Excel spreadsheets before pasing a row at a time down to the workflow service?
What Is A Reliable Way To Run Time Consuming Tasks In MVC2
Sep 15, 2010I need reliable way to run 10 different tasks simultaneously. For instance the first one would be sending emails, while the next one is cleaning rows from a specific table... so on an so forth.
I've used the Thread class and while it works well on my development machine (VS2010 internal web server) non of these threads seems to be working at all on my production server. And I don't know of an effective way to debug the problem on the production server.
I saw this technique which encourage you to register cache objects. Since the application fires a callback when a cached item expires, then it's possible to run any code to mimic threading behavior. It seems a little Micky Mouse like.
Consuming StackOverflow API And Visual Studio 2010?
Feb 14, 2011I have downloaded TheWorldsWorstStackOverflowClone. One of the project is called TheWorldWorsts.ApiWrapper, which basically is the core of accessing the API. There is a class called ApiProxy.cs, which has all the methods for the API call. This is good.
Now what I want to do is I am trying to collect data from this API interface and store it in a database. I know the limit to the API call is 10k per day. I.e: I want to be able to call the method in the ApiProxy class 10k times per day, done automatically. How can I do this?
The non-automatic way would be to create a dummy site where when every time I access the site it does all that process, but this not efficient. It seems that I have to write some kind of a scheduler by deploying a web service, but that is too complicated... as explained here. Any other simpler methods?
WCF / ASMX :: Consuming A Class Library From A Web Service?

End
Function
I get this error:You must implement a default accessor on System.Security.Policy.Evidence because it inherits from ICollection. And I can't seem to find any coherent instructions on remedying this issue.If I copy the Staff class into the web service (app_code) it works hunky dory, so it must be security..I can't be the only one attempting this! MSDN doesn't explain this one too well :(

View 1 RepliesWCF / ASMX :: Consuming A XML Web Service Slow On First Request?
Jun 13, 2010for the past couple of days i am facing an issue where the first call from my ASP.NET 4 application (VS 2010 Web Site) hosted in IIS 7 to an XML web service is dead-slow. subsequent calls are fast until the AppDomain is restarted.
I have tried all solutions related to pre-generating the serializer assembly but nothing worked. Anyway THEN I was sure it is an IIS-only issue because if i consume the xml web service from a console .net application then all the calls are fast. its even fast from an ASP.NET web site NOT hosted in IIS instead running on the development server. SO clearly the problem is there only when my app is hosted in IIS.
Consuming A WCF REST Service From Android Is Very Slow?
Aug 31, 2010I have a WCF REST service built with C# and it returns an image as part of a CPU intensive operation. The client is running on Android (Java) By default, it will return a text JSON object that looks something like this:
{"d",[9,0,77,12,11,...]}
Those are they bytes of the image. Fine. However, all the solutions for decoding this JSON are intolerably slow. I've tried Gson, Jackson, and the built-in Android JSONObject class. I have no idea why they are so slow.
As an alternative solution, I have my REST service return a GUID, and then that GUID can be used by the Android client to go to a regular URL that serves up the image as a regular binary stream, via an MVC controller.
This works well, and it fast, and is pretty easy to handle on the Android side. However, it does feel like a bit of kludge and kind of a violation of the REST design principles. Am I missing something here? Is there a better way to do this?
