I know how to use My.Computer.Info.OSFullName to get the version of the OS. How would I go about getting the Service Pack version?
I need this to work on all versions of Windows.
Also, is there a way to check and see if the activation has been successfully completed?
I can get the current version of the os but i cannot get its service pack.

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.

View 3 RepliesI'm trying to add functionality to my application that will disable buttons and checkboxes depending on what version the OS is when the app is launched. I made a test app to test this but unfortunately I can not get it to work. Here is my code:

I have created a license system for my application with MySql about half a year ago. What it would do is take the serial number and send it to my server if the key was correct it would return a 0 if its wrong the return value would be a 1.The problem was that when the serial number was entered correctly my program would create a "fake file" for example vb.dll in the system.And on run time my program would check for that vb.dll if the file exist it would skip my trial program and run the app as a full version. Half year later i think creating a "fake file" and checking for it on start up is extremely wrong and that's not very good security.How can i check the difference between a full version and unregistered version?

I would like my program to overwrite its previous version such that users don't have to uninstall the previous version before installing the new one.
I'm guessing it has something to do with setting Publish Version (Major, Minor, Build, Revision), Assembly Version or File Version.

View 1 RepliesI'm compiling and testing the VB programs in a download from MS of the Windows API Code Pack at url...(which is in VS 2008 and needs to be converted to run on VS 2010). So far I've resolved most of the issues, but a couple are baffling.The code as downloaded for the Taskbar demo refers to icons in the project resources as My.Resources.Green and My.Resources.Yellow and Red. Fatal errors, even though all the help pages say this is the correct way to access them. I got the build to run by removing the "My."; has there been a syntax change between VS 2008 and 2010? When I run the app, I get a message from TaskbarDemo.vshost.exe which says "This demo application needs to register .txt files as associated files to properly execute the Task related features. Filetype is not registered." Does that mean that in trying to debug the app, I have to modify the registry to associate the test program with the .txt filetype?
