I developed a Web Service which calls a ProcessStartInfo class. When I run the WS in debug mode, step by step, It works fine but when I publish the WS, It just does not work and does not even throw any exception. I gave full permissions to ASP.NET and Network users on the .exe which the PSI calls.
View 2 RepliesThis 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.
i have been deploy webservice in vb.net .
is there will be any problem if i will cal the webservice from c++ (version 6) or Microsoft Access VBA?
I call upon your combined intellects. I have a web application with a silverlight app that calls a ria service. The ria service is defined inside the web application and everything else is just dandy.
The issue is this.It is my understanding that in order for the silverlight application to talk and know what the ria service is, you need to add a service reference for that service. The service reference defines the ria service and sets up the connection binding. One of the files it adds is the ServiceReference.ClientConfig which has the connection binding in it. During the course of this application's development, this is the way it was set up. And it worked perfectly fine locally and on the dev server.
Unfortunately there were issues when deploying to the clients in-house server. At this point I was onto other projects while my co-worker continued with the deployment. He soon became frustrated with the goofy errors that were occurring and recruited some help. This dev came in and, albeit got it working, but in order to do so he removed the service reference from the silverlight project but left the ServiceReference.ClientConfig which pointed to the location of the service in the web application(but that's it, no definition or explanation as to what the service does and I'm not sure how the silverlight app is supposed to know how to work with it..). This works perfect on my co-workers workstation and he has deployed this version to the clients server fine.
When I open the project it doesn't run at all. And the reason why is that it doesn't know what the service is that i'm using in code. Specifically, it doesn't know where this is (names changed for clarification):
Imports SilverlightApp.ServiceReference.WebApp.Service
I have cleaned the solution, completely deleted and got the latest from source control, built the web app first and made sure the asp.net dev server was running so that the address in the ServiceReference.ClientConfig resolved correctly. But, alas, it still doesn't know what Imports SilverlightApp.ServiceReference.WebApp.Service is.
So, to get it working on my workstation, I added the ServiceReference back but kept the current connection bindings so that it matched the endpoint in the web app web config. and changed the import statement to Imports SilverlightApp.ServiceReference and everything works fine.
Is it possible in .net 2.0 to enable calling web service only from localhost and to disable calling web service from outside?

I have been given the task of calling a web service which returns an xml data feed which I am doing like so:
For Each r As DataRow in SomeDataTable
Dim msFeed As String = string.format("[URL]?param={0}", r!SOME_VAL)
Dim x As XDocument = XDocument.Load(msFeed)
Next
This is all fine but as you can see x just gets overwritten with every iteration. What I need is create an xDocument and add each feed from my loop but I am unsure how to proceed.
Solution
Dim xAllFeeds As XElement = New XElement("Feeds")
For Each r As DataRow in SomeDataTable
Dim msFeed As String = string.format("[URL]?param={0}", r!SOME_VAL)
Dim x As XDocument = XDocument.Load(msFeed)
xAllFeeds.Add(x.Root)
Next
When I try to call a [Java] web service from .NET, I am getting what appears to be a security credentials issue.

At this point, I just want to make contact with the web service and get access. In my example, ServiceReference1 is a generated Web proxy class.

It works great for text, Word, RTF, Excel, PDF, etc. However, images load by default with Windows Picture and Fax viewer and then don't print.It looks from the MSDN docs like I should be able to reset the default application assigned to the extensions and then maybe I could find another app that will print properly. And the OS acts like it's doing that. When I double-click on the file it does open with the new app. But when the above sub runs, it reverts back to trying to open with Windows Picture and Fax Viewer.
I have a utility that I have written in VB.net that runs as a scheduled tasks. It internally calls another executable and it has to access a mapped drive. Apparently windows has issues with scheduled tasks accessing mapped drives when the user is not logged on, even when the authentication credentials are supplied to the task itself. Ok, fine.
To get around this I just passed my application the UNC path.
process.StartInfo.FileName = 'name of executable'
process.StartInfo.WorkingDirectory = '\unc path'
process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
process.StartInfo.Arguments = 'arguments to executable'
process.Start()
This is the same implementation I used with the mapped drive, however using the UNC path, the process is not behaving as if the UNC path is the working directory.
Are there any known issues setting ProcessStartInfo.WorkingDirectory to an UNC path?
I have an application that runs using as AsInvoker manifest, this uses ProcessStartInfo to run another application that is using a HighestAvailable manifest (in my case this runs as Admin and I get the UAC prompt) the first app then quits. The second app then uses ProcessStartInfo to run the first app again, this time it runs as admin (no UAC prompt) I guess this is correct because it is AsInvoker and it is being invoke from an application that is running as admin, but I actually want it to run without Admin rights - or more correctly run it with the lowest possible execution level..I know you can use ProcessStartInfo.Verb = "runas" to elevate but can you descend?
View 2 RepliesWe have a piece of software that attempts to print .tif images using a ProcessStartInfo object. It sets the Verb property to "print" and the FileName property to the path of the image. It then sets the UseShellExecute property to true and executes the Process.Start() method.
However, nothing happens. I created a small test program to list the Verbs associated with .tif images and it only shows "Shell", but not "print".
I cannot modify this piece of software, so is there a way to define or register the "print" verb for .tif image types to allow them to print?

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.

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?

View 1 RepliesI'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?
View 1 RepliesWhen 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?
how to deploy a service made in VB.net. Most of the websites just say use installutil.exe this is fine while your testing your service on your local machine whit vs2010 on it. I am in the final stage now of my service like 99% is done and my last % is how to get my service installed on the server i need it on. I can't publish because this wont work with a VB.net Service Project. So all i want is a clean and easy Tutorial or Someone who can explain me how to do this without the need to install VS2010 on the server to get install-util.
