Then code a log analyzer. .NET is too high-level, as I said in my email, for such a task. Software firewalls must be integrated at a very low level with Windows, something that C/C++ is more suited for. A firewall must be very efficient and must hook the internet connections in Windows, which also works differently on different Windows platforms.

Even writing the firewall will require a ton of marshalling and P/Invoking...
C# and VB.NET are too high a level for the projects your coming up with. A firewall app would be better written in C++. Maybe not the entire app, but the filtering engine would definately be C++, maybe even Managed C++. You could write management interface for the engine in C# though.

[DllImport("kernel32.dll", CharSet=CharSet.Auto)]
static extern IntPtr LoadLibrary(string lpFileName);
[DllImport("unmanaged.dll")]
static extern int YourFunction(int i);
string path = @"..\somedir\own.dll";
IntPtr ptr = LoadLibrary(path);
int i = YourFunction(7);
In .NET 2.0 you will be able to do this:
[DllImport("kernel32.dll")]
internal static extern IntPtr LoadLibrary(String dllname);
[DllImport("kernel32.dll")]
internal static extern IntPtr GetProcAddress(IntPtr hModule, String procname);
internal delegate int MyMsgBox(IntPtr hwnd, [MarshalAs(UnmanagedType.LPWStr)]String text, [MarshalAs(UnmanagedType.LPWStr)]String Caption, int type);
IntPtr user32 = LoadLibrary("user32.dll");
IntPtr procaddr = GetProcAddress(user32, "MessageBoxW");
MyMsgBox msgbox = (MyMsgBox)Marshal.GetDelegateForFunctionPointer(procaddr, typeof(MyMsgBox));
msgbox(IntPtr.Zero, "Hello, World", "A Test Run", 0);

You can do it thought the registry. Or, I guess you could mess around with the taskman executable in the sys dir or somewhere...

But, the real question is: Is that really all that wise?

Can't manage to P/Invoke that Win32 API in .NET? Why not do interop the wiki way!

You can take the fifth if you want to. It is your constitutional right.

My windows service is working fine in WinXP SP1, but it can't start in Win2K Server SP4. The error message is: "The service did not respond to the start or control request in a timely fashion."
Any idea?
Thanks

That's a very generic error message for any service that can't start. I recommend you set the AutoLog property to true and check the event log (eventvwr.exe) for more detailed information.
It may be that you're using functionality only supported in XP and newer, but without more information it is impossible to determine.

AutoLog is set to true. Another message that I get from EventViewer is "Timeout (3000 ms) waiting for the service to connect".
I do not use any XP specific function. In fact, my OnStart() and OnStop() are empty.
Thanks for your response.

You might explain what your service does, then. Like I said - any service (native, .NET, VB, whatever) will report that (it's actually the service control manager (SCM)) when any error occurs. It expects that the service itself will report additional information in the event viewer (like it should).
If you link against other assemblies (besides the .NET BCL assemblies), make sure they are in the same path, in the GAC, or in a path configured in your service's .config file. Read How the Runtime Locates Assemblies[^] in the .NET Framework SDK for more information about how assemblies are located.

Just be clear, I am talking about "Windows service" not "web service."
|
|
|
|

Web.config is what ASP.NET uses. Windows applications that are launched by the executable loader use the "appname.exe.config" file-naming convention. It's all about what sets up the default AppDomain, loads the AppDomainSetup, and loads and executes the target assembly.
