Webcam Application As Service
Jun 30, 2009
I have created a webcam application. It uses a PictureBox to display the image and saves the image to file via the clipboard. I've used code found on this forum and all works fine.
What I'd like to do now is to convert the application into a service.
I know how to create a service, but does the webcam image have to actually appear on the screen to save the image? My goal is not to have any forms display on screen, therefore conforming to typical service operation.

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.

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.

I have a logitech webcam that I use to take pictures of customers to submit to a server/database. Utilizing AVICAP32.DLL calls, I was able to modify my VB.NET program to take these pictures via a button in my program.
My question is, it would me more convenient to my intended users to click the webcam button, instead of clicking on the button in my program.
Is this possible to do in VB.NET? and how can I do this?
If this is not possible to do with my logitech webcam than is there a Microsoft Webcam that can do this?

I am having a hard time figuring out how would my vb.net application to run as window service so that it would not appear in the task manager's processes list so that it can't be terminated and would constantly run in a background. Is there anyway we could make to run our vb.net application as Windows Service, programmatically? If not, could you provide me sample code that has this Windows Service that's constantly from time to time check whether my application is running or not? If not, then the Windows Service will rerun it for me.?

I created a very simple web service on my godaddy shared hosting web site, using VWD. I wrote a VB app to use some web services. I added a web reference to another web service with no problem. But I could not add a web reference to MY OWN web service. It was blocked by a Discovery Credential dialog that could not succeed. After days of communication with godaddy tech support they stated it could not be done (for security reasons).

I am creating a desktop application that uses a SQL database to store information about different movies. Instead of having to type in the information I want (Barcode code, DVD ID, Title etc.), I want to use a web service. However, I don't know any web services like this and I am new to trying to implement them. Can anyone suggest a good one and briefly tell me how to implement it into my app?

I have created and deployed a windows service application and I added this line of code "System.Diagnostics.Debugger.Launch()" in the beginning of OnStart method in order to be able to debug the service but when I start the service the nothing is happened. I think the OnStart method have never fired otherwise the visual studio will popup once the debugger.launch line is executed even I tried to write some text to the event viewer to make sure but nothing gets written to the events viewer after I started the service. I included also the debugging symbol in my windows service setup project but I end up with the same result.Why it's not working? How can I make sure that the OnStart method gets fired or not?

installutil KleinDevortService.exe

I made a client/server application and I want the server application to be a service that can have it's setting managed through a GUI.I know how to make an application a service, but how would I give it the ability to have its settings changed and start/stopped through GUI?Or would you just make a program that can edit a certain server's config files and just restart it to pick up the changes?

I created new windows service with timer inside it for scheduler purpose and it can run successfully but it can't run other application (ex: notepad) when the timer elapsed. I can see the process running in Task Manager but the notepad windows is not open. I used this code in timer_elapsed event.
AppLauncher oAppLauncher = new AppLauncher(@"C:WindowsRegedit.exe");
new Thread(new ThreadStart(oAppLauncher.StartProcess)).Start();
where applauncher is a Class
Class AppLauncher {
string myAppPath = string.Empty;
[Code] .....
When I build windows App I can see Notepad open using the same code.

I have an application right now that requires a few different DLL's and some other command files and such. The problem I have with running it the way it is that it requires me to transfer the installer to my customers machine and then install the app i have built run it to get the report back i need.Network based to run this wouldnt work as all the customers are behind firewalls and it would take a miracle to get it opened up to make this work. So what i was hoping was to convert it to a web service/web app where i can have it run that report.
