Re: HTTP Tunneling in C# without proxy server

Basically when you create an open connection in your c# application you pick a specific port. The SSH tunnel then captures that port and tunnels it for you automatically.

Really though from the questions you are asking disabling the port on the firewll seems like the right answer.

The ID3 Version 2 tag is very complicated and pretty complex to parse.
You might want to check the much easier ID3 Version 1 tag. It's typically at the end of the MP3 file, starting 128bytes from the end to then end. If there is an ID3v1 tag, then the last 128bytes start with 'TAG'.
It's very easy to read and write.

Check google for the exact format of the ID3v1 tag.

Put the mp3 in a text editor like "Notepad" and read the last 128 characters of the file. If it commences with the word "TAG" its a type 1 id3 tag.

Hi,
Because of the requirements of my project, I have to create a downloader/updater installation. I've got the download part working just fine, but when I loop through the dlls to decide which versions I overwrite I've come across a problem.

As soon as I do Assembly.LoadFile( toFile) to get the version information of the from and to dlls they are loaded into the AppDomain.

So, I've been reading and it seems I have to create a new AppDomain, but no matter what example I find I can't follow it from there. All the examples seem to assume I'm going to want to use the loaded assemblies to create something. I'm simply wanting to do a straight comparison of version info (the app is nothing complex) and replace if newer in version numbering.

Any ideas / hints?

Why do you need to do Assembly.LoadFile? Wouldn't FileVersionInfo work as well? This can be used to read the version data from the DLL without loading it into the AppDomain.

No problem. In my opinion, the FileVersionInfo class is a bit hidden to be commonly used. The best way to learn is to try and find the answer yourself and when that fails (or doesn't work the way you want/expect it to) ask questions.

We all learn as we go, as everyone has different experience with the Framework.

Installation of windows service ?????

Hi there,

I have written a basic windows service that creates a text file and write some data in it. I have also written a windows service installer for that.

Now when I try to install it by using installutil (c:\windows\microsoft.net\framework\v2.0.50727), I get the following error message:

No public installers with the RunInstallerAttribute.Yes attribute could be found in the c:\...\windowsservice.exe assembly.
Remove InstallState file because there are no installers.

Can someone tell me why is that so??????????

Thanks.

Hi,

Have you generated the ProjectInstaller class?

It should look something like:

<br />
	[RunInstaller(true)]<br />
	public class ProjectInstaller : System.Configuration.Install.Installer<br />
	{<br />
        ...<br />
        }<br />

Uninstall removes files and leaves executable running

Hi,

I have used VS2005 to create a .msi package for my software. The problem though is that when I uninstall the software either through "Add/Remove Programs" or through running the uninstaller again, the uninstaller will remove all of the files but leave the executable running.

Is there anyway to have the Installation project stop the executable, both when the application is in window form and when the application is in the system tray?

Thanks,
Adam

Hi,

you could use a FileWatcher and teach your app to exit gracefully when something
happens to a specific file (rather than an installer trying to kill your process !)

That worked! Thanks for your help...I put a FileWatcher in my application and told it to watch deletion of the .exe. On deletion, then call Application.Exit() and that worked great!

Many thanks,

assign data to object from webservice

I have assigned a variable of type object to a method.
i.e. object o = getDataFromWebService(int intData);

Then hovering over o or looking at the values in Locals Window for o, I can see the data has been returned. Something like:
o[0]
o[1]
o[2]
etc...
Theh for each index, in the locals window I can see the fields returned also.

In code, how can I refer to these values please?
I tried something like:
string x = o[0].ToString();
but I get this errorL:
Cannot apply indexing with [] to an expression of type 'object'

Thanks

Cast the object to the appropriate class. I can't tell you what that is because you have not supplied sufficient information.

I actually want to open Notepad on a remote machine.

By writing the following code, I am able to run it, but the problem is that it is runs in background. I can only see it by opening up the windows task manager of the remote machine.

ConnectionOptions objConnectionOptions = new ConnectionOptions();<br />
objConnectionOptions.Impersonation = ImpersonationLevel.Impersonate;<br />
objConnectionOptions.EnablePrivileges = true;<br />
objConnectionOptions.Username = strUserName;<br />
objConnectionOptions.Password = strPassword;<br />
ManagementScope objManagementScope = new ManagementScope(@"\\remote-computer-name\ROOT\CIMV2", objConnectionOptions);<br />
objManagementScope.Connect();<br />
<br />
ManagementClass processClassFinal = new ManagementClass(objManagementScope, new ManagementPath("Win32_Process"), null);<br />
ManagementBaseObject inParamsFinal = processClassFinal.GetMethodParameters("Create");<br />
inParamsFinal["CommandLine"] = @"c:\windows\notepad.exe";<br />
ManagementBaseObject outParamsFinal = processClassFinal.InvokeMethod("Create", inParamsFinal, null);

Is there anyone who could help me in sorting out this problem

Thanks.

Hi.

Where and where from exactly do you want to load a file?
For example, loading to Bitmap you can do like this:

Bitmap bmp = Bitmap.FromFile("C:\\image.jpg");

And you can use it for example to set your Form BackgroundImage property:

this.BackgroundImage = bmp;
