Consume Web Service In A .NET App?

Dec 3, 2009

I'm pushing the bounds of what one should ask of others with this one, but I'm totally stuck, so here goes.This is my first web service. Not only that, it's my companies first web service - nobody I work with has ever written or consumed anything like this one. I know these things are not complicated, but for a first kick at the can, this is killing me because the API is so large.

How To Consume / Access A Web Service

May 9, 2010

I need to write a Windows forms app in VB 2008 to communicate with a Web Service.I have searched MSDN and many other sites trying to find a good tutorial or example code with no luck.  The one really good piece of code I found did not compile.It needed to import Microsoft.UDDI.I found numerous references to the UDDI SDK, but could not find any site where I could successfully download it.I have the UDDI.dll but it is in my VB 8 folder and would not register.There is no such ddl in my VB 9 folder.

Getting A Compact Framework 2.0 App To Consume A WCF Web Service?

Mar 10, 2011

We are in the process of creating a new WCF web service (WCF service that has an basicHttpBinding Endpoint) to carry out some of our business logic. The web application connects not problem at all, however our legacy Compact framework application doesn't seem to see the service at all. Are we on to a loser here and should we just revert to ASMX web service (the Compact framework cannot be upgraded) or is there a way around this?

How To Consume A Web Service In A .NET Class Project

Dec 14, 2009

I want to create a class library .NET web project that encapsulates the functionality of consuming a web service. I can create the .NET class web project and add a web service (Visual Studio 2005) but I cannot seem to figure out how to reference it. It's easy to reference in a web site (simply address it by name), but apparently in the class library project things are different because I cannot figure out the namespace or reference name.

C# - Consume A SOAP Web Service Without Relying On The App.config?

Sep 13, 2010

I'm building a .NET component that will call an external web service. I used the "Add Service Reference" dialog to add the web service to my component, which generates the code needed to consume the service and adds the settings to the app.config file.I'm testing the component by adding a reference to its DLL from a Console application and calling the appropriate method that creates a new instance of the web service: ... = new MyServiceSoapClient(). However, when I do this, I get the following exception:


Could not find default endpoint element that references contract 'MyServicesSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.This makes sense since the app.config isn't being brought over with the component's DLL. How can I call the web service without having to rely on the settings in the App.Config?

.net - WCF Service Hosted In A Managed Windows Service Connect Using A WCF Service Application

Jul 14, 2011

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:

Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.

It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

Consume A StreamReader Stream .NET From A Web Request As It Streams?

Nov 12, 2011

I experimenting with the Twitter streaming api, an am trying to open a stream for a user to consume events as they happen. I using a standard set of classes for making REST api calls to twitter. When using url... in a "GET" call the response stream never ends.I'm opening a StreamReader and reading the response as I would with any other REST call to Twitter. This is probably obvious to others, but how do I "consume" this stream... Is there a way to read the StreamReader as it's reading (meaning before it closes)? or maybe there a different method I can user to consume this stream.... again, I apologize if this seams to be elementary to some, but I can't figure it out at the moment. Here is the original source I started troubleshooting this with.This method was fabricated from a set of C# Classes I found in a forum on LinkedIn. At the line that reads "responseData = responseReader.ReadToEnd()" the method starts to "drink" the stream... but do so like a bottomless cup... reading this stream of data in real time before it closes (which is essentially until I stop debugging or kill the process) is the question I'm tackling.[code]

This write the opened twitter stream to the file, and every time I Tweet, Retweet, Delete, Direct Message... and so on.The file grows with a JSON object appended to the text. I used the Do While 0 < 1 for testing here, because I just wanted to see it working. I see on MSDN StreamReader Constructor Description that the New constructor is supposed to accept a Boolean value for "leaveOpen", but no such argument allowed when I try to add this to the constructor.Does anyone have a good example of how to do this with forcing and infinite loop or just a better approach than this... I would like to simply read new updates sent each time from Twitter, and address them accordingly? There is obviously a way, I'm just new to the concept of consuming a stream like this with out it being closed.

Dynamic SQL To Dynamic LINQ In .NET With MS SQL Server 2008?

May 24, 2010

I need to represent the following query using LINQ:

DECLARE @PurchasedInventoryItemID Int = 2
DECLARE @PurchasedInventorySectionID Int = 0
DECLARE @PurchasedInventoryItem_PurchasingCategoryID Int = 3
DECLARE @PurchasedInventorySection_PurchasingCategoryID Int = 0


Now, I know that a query in .NET doesnt look like this, this is my test in the SQL Design Studio. Naturally VB.NET variables will be used in place of the SQL local variables.My problem is this: All of the conditions after "WHERE" are optional. In that a query might be made that uses one, some, all, or none of the conditions. V.PropertyID and V.Value can also appear any number of times.In VB.NET I can make this query easy enough by simply concatenating strings, and using a loop to append the "V.PropertyID/V.Value" conditions.I can also make a Stored Procedure in MS SQL, which is easy enough.However, I want to accomplish this using LINQ.

VS 2008 Dynamic Timer In A Dynamic Form

Feb 19, 2010

Ive managed to dynamically create a form, and dynamically create a timer, but i have not been able to create the timer on the dynamic form. Specifically, i need to be able to have the timer itself create another form with a timer. (I realize that this would create a new form every interval on the timer, that is what i want to do)

1. A way to add the timer to the dynamic form, and maintain the timer sub on my main form.

2. A way to create the whole thing over (dynamic form and timer) through the previous dynamic form and timer.

I was thinking i could use a collection/array to store the forms and timers, but i'm still having trouble figuring out how to add entire forms or timers into a list. (A timer is not considered a control, so i cant use a controlcollection...)

Heres my code;

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim frm As New Form


*EDIT* Btw, my idea was to use i as a variable that increases every time a form is created, then insert the form into the array, with i as the integer. i just need to know how to create a new form with a different name each time. (as with timers)

When you hover over a label there will be a different contextmenustrip to appear for each and every label. So all the contextmenustrips are Dynamic and contain 1 option maybe 2 options even 3 or 4 up to the users settings.

My problem is not creating a handler for when the user clicks on the contextmenustrips options. The problem is knowing which one of the options for that contextmenu was clicked!!

Dynamic ToolTip For Dynamic Text Box?

Jan 11, 2012

OK, I'm trying to display tooltip text for a dynamic edit box. Well, at least I'm trying to.

On my form, I've got a tool tip control which I've conveniently named ToolTip. My edit box displays OK. But, what I want to do is when the user hovers their mouse over the text box, I want the tool tip to display some text.

I think there are two problems that I'm having. I'm not convinced that I'm properly addressing a dynamic text box name. Ideally, I would want to be able to refer to the text box (but using a dynamic variable that will contain the prefix of the name). To hardcode, I would want to be able to achieve (not in this example but in theory): ABCDEFGt_0300.Text = "hello"

Dim controllerName as string = "ABCDEFG"
Dim t_0300 As New TextBox()

Service Reference Stops Working When Make Changes To WCF Service?

May 26, 2011

I'm using Visual Studio 2010 and .NET3.5. I've created a WCF service application. I'm including two DLLs that contain the types I'm returning. The first method I wrote works both in WCF Test Client and also in a console application I created to test. When I move on to the next method that returns a generic list of a type. It works great in WCF Test Client, but when I update the service reference it acts as if the service is unavailable. All my objects say can't find reference, and I can no longer see it in the object browser. It's like it just disappears. I can still see it in the Service Reference folder. If I go back to the WCF app and comment out the contract and implementation of that one method it work again. I created a local class very similar to the class I'm using from the dll, and the it works. Is there something I'm missing here? Can someone point me in the right direction?

Windows Service: Multiple Instances Of The Same Service Class?

May 3, 2011

When you create a Windows Service, you create a list of the services you want to start. The default is this:

ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service}

Can you have multiple instances of the same Service class (that bind to different addresses or ports), like this?

ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service("Option1"), New Service("Option2")}

Or will that cause problems? Should we use two different classes instead?

Install Windows Service Using A ProjectInstaller And A Deployment Project ("Specified Service Already Exists")

Mar 10, 2009

I have the project installer class in the service project and I've added the "Standard output etc.." from the service project as custom actions for the Deployment Project. When I attempt to install it, I get the error "Specified service already exists", which shouldn't happen (even though the service does exist) because the installer should be removing the old service and installing the new one.

I've checked that the versions are different, and that the Product Code is also different, also RemovePreviousVersions is set to true. Can anyone tell me why it isn't uninstalling my old service when I update then install again? .S: MODS: DO NOT MARK MY POST AS ANSWERED, IT IS RUDE, YOU HAVE NO IDEA IF YOU'VE ANSWERED MY QUESTION!Sorry, it gets ignored in my signature.Mods
