How To WCF Service External To Solution With AutoCompleteExtender
Jan 31, 2012
I've coded a WCF service that is external to the solution I wish to use it in. I'm doing this so that I can have one service that's reusable across many solutions. We've already duplicated this service many times as an asmx integral to the solution and it's not a good maintenance scenario. I'm finally able to have time to tackle gettign this working the right way.My solution (and the service) is in VS2010, Framework 4.0, vb.net.When using the webHttp..Binding binding in the endpoint, when I add the service to my solution the reference is getting added, but web.config does not get added with the system.serviceModel configuration group that is needed.[code]

Basically, I'm delving into the world of the AjaxControlToolkit today, with the main aim of fulfilling my AutoComplete requirements. I've set everything up as tutorialised and am a little confused as to why things aren't working (well I have an inkling as to what may be holding me back).
I've added the AjaxControlToolkit dll to my project and in my Markup I have the following :
at the top
CODE:
then within my content
CODE:
Then in the code behind, I have my nice little function (which the breakpoint within is never reached)
CODE:
The function is never being called, for a reason I am unsure of.
Potential Issues. There are a couple of potential issues where things may be going wrong:
I've tried adding the AjaxControlToolkit dll to the Toolbar in VS (2010), but all the controls are greyed out...The GetCompletionList function (WebMethod) I have written is in the code behind the page. Could this not be called because it has to be in a Web Service perhaps? I've also just realised that my function in the code behind isn't Shared, is this required? Because the list associated with the auto complete is dynamic.

In a page to create new user accounts, we have a database with a little of allowable users. To streamline getting the Email address of the new user correct, we want to use an AutoComplete extended textbox.Now I know that WebMethods are working because I have a cascading-drop-down tied to web methods in another page.As I'm just starting on this page, the code is simple.The page itself:
<cc1:ToolkitScriptManager ID="ScriptManager2" runat="server"/>
<p></p> Please enter new user's Email:
<asp:TextBox ID="txtUser" runat="server" />
<cc1:AutoCompleteExtender runat="server" ID="autUser" TargetControlID="txtUser"
[code]....
I'm not even getting to the LogDebug statement. I've used all the same boilerplate code (Inherits, the 'WebService' tags, etc) that worked in the other WebMethod with the appropriate changes to the Class name but this really has me stumped.

I have a problem regarding the autocomplete extender in ASP.NET - it works fine in all pages I have, but NOT in a master page and i don't know why.
Here is my code:
<asp:TextBox runat="server" ID="txtSearch" Width="200px" CssClass="TextBoxClass"></asp:TextBox>
<cc1:AutoCompleteExtender ID="txtSearch_AutoCompleteExtender" runat="server"
TargetControlID="txtSearch"
[code]....
The problem is that GetCompletionListOggetti is never called. I repeat - it works fine on content page!

I had a problem (which is now fixed) but I've no idea why.I have an Ajax AutoCompleteExtender with a WebService method to populate like <WebMethod()> _
Public Shared Function populateACE(prefixText As String) As List(Of String) However this didn't work - I put a breakpoint in, and it didn't even get hit. However... <WebMethod()> _ Public Function populateACE(prefixText As String) As List(Of String) does work (the only difference being not Shared).
Fair enough, but why? If you have an instance of a class then you can access Shared methods of it; if you don't have an instance of a class then you can access Shared methods of it. So what is going on behind the scenes?

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.

I wanted to know if it is possible to Zip a folder without any external dll nor any external references - just with native features.I've been able to Zip files with System.IO.Packaging, but it does not include folders and I cannot tell it to Zip the parent folder.I know there are external dll and so, but I'd like to know if it's possible to make it from a native way.

This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.

In the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?

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?

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?

We have a server with multiple services written in .Net 1.1 and 3.5 running on a Win 2003 server. Everything runs fine, but when we stop a certain service, an unrelated service stops. I have checked and neither has any dependencies. The service we stop is in 3.5, and the unrelated service that incorrectly stops is in 1.1. We get no error messages, nor event log errors, so we are baffled.Does anyone have an idea as to what may be causing this?

I inherited a working WCF Web Service with one major flaw - the WCF Service consumes memory and does not release unless the service is restarted. After a half a day of requests hitting the web service, the memory on the server hosting the service climbs to close to 2 gig and is dead in the water.
I'd like to be able to release memory after the web service has received its response but cannot figure out how (WCF is still new to me). [code]...

I've created a windows service and started a deployment project for it. 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

I am working on a .NET Windows Service where I am trying to store settings that will be used when the service is started and while it is running. I have searched through posts on SO and found that using the Settings in the properties of the project is great for use with console and winforms applications. However, Google and SO are silent when it pertains to storing these settings with a windows service.
