Installing Windows Service omkamal17-Jan-02 4:50 omkamal 17-Jan-02 4:50  Hai, I wrote a windows service application using c#. I am able to install it using InstallUtil.exe provided by .NET framework. But I want to install the same service on a different machine which does not have .NET framework. I think, InstallUtil.exe comes only when you install .NET (correct me if I am wrong). But I dont want to install .NET framework just for this utility. Does c# provide any class which can be used to install a service? I read about ServiceProcess.ServiceController. But this only helps me to monitor the installed services. Any suggestions... omkamal Re: Installing Windows Service omkamal17-Jan-02 6:17 omkamal 17-Jan-02 6:17  Oops Sorry folks. I read that you need .net framework to atleast run a .NET application ( no matter its a service or whatever ). So there is no way but to rely on InstallUtil.exe. Thanks anyways omkamal System name using C# 16-Jan-02 7:50 16-Jan-02 7:50  Hai, Can anyone tell me how to get the name of the computer (in which the code is running) using c#? thanks. Re: System name using C# Fazlul Kabir16-Jan-02 8:46 Fazlul Kabir 16-Jan-02 8:46  Thought this one should do String s = System.Diagnostics.Process.GetCurrentProcess().MachineName; // Fazlul Get RadVC today!

This is what I found out. I dont think there is a direct GetComputerName function in c# (as far as I know). Instead I read the following registry key HKLM\System\CurrentControlSet\Control\ComputerName\ComputerName. I hope this key is created in all machine because the System subkey stores sys related info. If anyone wants to know the computer name, this is next to a good solution. Use, Microsoft.Win32 namespace for Registry related classes in c#. One more thing "Naivete" and "omkamal" are one and the same. I just changed my username. Thanks for your help. omkamal Re: System name using C# Fazlul Kabir17-Jan-02 2:46 Fazlul Kabir 17-Jan-02 2:46  You're right, it doesn't work on my system either. According to .NET documentation, MachineName property should return the name of the system Gets the name of the computer the associated process is running on. // Fazlul Get RadVC today!

Sorry, I was obviously mistaken. I guess you can try SystemInformation::ComputerName, as suggested in another post. // Fazlul Get RadVC today!

I appreciate your reply. I was so surprised how come c# doesnot provide such a functionality. But shame on me, that I felt so frustrating to check every single class for it. Nor did I try different search strings. Thanks again, Omkumar. omkamal Re: System name using C# Fazlul Kabir17-Jan-02 4:44 Fazlul Kabir 17-Jan-02 4:44  Thanks, this worked. // Fazlul Get RadVC today!

Re: VS.NET and Product Activation Konstantin Vasserman16-Jan-02 5:12 Konstantin Vasserman 16-Jan-02 5:12  I did not install it yet, but it does not look like it will need activation, because a key is provided to MSDN subscribers.

Phil Wright phil.wright@crownwood.net Downcasting in C#? Gerald Schwab15-Jan-02 13:15 Gerald Schwab 15-Jan-02 13:15  How do I simulate downcasting in C#? public class foo { } public class bar : foo { } foo f = new foo(); // The following line // causes a run-time error. // InvalidCastException bar b = (bar)f; ************************ The following doesn't work either. This gives a compile error. public class foo { } public class bar : foo { public bar(){} public bar(foo f) { this = f; } public static explicit operator bar(foo f) { return new bar(f); } } Re: Downcasting in C#? Peter Stephens16-Jan-02 7:04 Peter Stephens 16-Jan-02 7:04  AFAIK that can't be done in C#. The 'foo' object never was a 'bar' object and can't be cast in that direction. A new 'bar' reference CAN be cast into a foo reference and then back into a 'bar' reference though. You cannot cast this way in a strongly typed language. You may be able to do this in C++ (with reinterpret_cast) but the virtual tables will be messed up and strange bugs WILL happen. -- Peter Stephens Combine ListView and TreeView 14-Jan-02 22:08 14-Jan-02 22:08  I need to build a dialogue containing a 2 columns ListView while one of them is a TreeView format.. Does anyone know how can I do that?? Thanks a lot for your help in advance Mail Encoding and Decoding Problem 14-Jan-02 20:34 14-Jan-02 20:34  Hi, I want to parse a mail from POP3. Everything is OK except decoding a message. For example, if I just mail to myself through a UNIX console, I write a "Test" to Subject. i,e. "Subject: Test" But through a Outlook Express or Other Mail Client Tool, Subject is =?euc-kr?B?vNvAzsf... like this. so, I must parse this encoded message. "euc-kr" is a encoding type? then How can I convert this to UNICODE or just other type. Please help me ^^; Dynamic Assemblies 14-Jan-02 2:15 14-Jan-02 2:15  Hi, Does anyone know how i can load assemblies in my program at runtime or DLL's of managed code ? Ive seen a class in System.Reflection called Assembly but i am unsure if this is what im looking for. I am trying to create a plugin system for my program which scans a directory for DLL's and loads them up. The loading is the easy part, im just looking for a way to make my program aware that other assemblies exist and to load a default class supported by every assembly at runtime. Hope that makes sense. Any ideas on how i would go about this ? Cheers Re: Dynamic Assemblies Joao Vaz14-Jan-02 3:53 Joao Vaz 14-Jan-02 3:53  Hi, You have the System.Reflection.Assembly.Load method that accepts a assembly name or a assembly ref that does precisely what you want. Cheers, Joao Vaz Re: Dynamic Assemblies James T. Johnson14-Jan-02 15:33 James T. Johnson 14-Jan-02 15:33  I feel extremely bad about doing this, but I wrote a couple articles for CP that do just what you're looking for. Look for "TypeLoader for .NET" for some code you can plug in to your existing application, or look for "Using reflection to extend NET programs" to get a more in-depth look at what typeloader is doing.
