How to get the user fastswitch, User Logon and logoff event

aocraft5-Jul-05 15:13

5-Jul-05 15:13

I want to free up the network while the user is logged in to the machine.
Basically I will be running azurues on a machine that my family uses. They have all different logins to the machine. Mum, Dad, Sister, etc.

When I have azureus running under my account they can't browse the web becuase I am chewing up all the network. User fast switching allows my account to continue downloading through azureus ... while someone else logs in to browse the web and check their emails etc

I don't want to give them access to my account to pause/stop azurues.
I can build a small app that can talk azurues by using azurus xml over HTTP plugin. This is not a problem. But I don't want to have to have them manually stop/start azurues with this app as they may forget to restart it.

I wanted to make the whole process automated. So I was going to write a NT service that will pause azurues when a user logs in and resume download when they log off.

But I am not sure where to start looking to get the logon and logoff event.

It would be good if I could get the user id that is logging on and off So that I can select which accounts will pause azureus and which will allow it to continue running (ie my logon account).

Reusing threads?

Hello everyone! Big Grin | :-D

This is my first post here! Smile | :)

OK, I made some kind of music player that plays the music in a different thread... When the user clicks the "Stop" button, the thread stops, but then I can't restart the thread when the user clicks "Play" because I get a ThreadAbortException! What can I do? Thank you very much! Wink | ;)

It's not possible to reuse aborted threads. What you can do is simply stop and wait instead of aborting the thread. Something like

void ThreadFunc()
{
   while(true)
   {
     if (isStopped)
     {
        startEvent.WaitOne();
     }
     
     // play your file.
   }
}

No, just name the thread when you make it, then stop it, then use this trick:

[code]Thread.FreeNamedDataSlot(string name);[/code]

And then you can restart it! Big Grin | :-D

Thanks for your help though! Wink | ;)

.net 2005 beta2 auto generated staic class

hello

I have a question about the static class that is auto generated when you create strongly typed resources. The question is how do i make the class and properties stay public in shared resource-only assemblies, when i need to update the resources, becasue the code is auto generated when you update the resource. So the class and properties change back to internal is there a work around ????

thanks in advance

It's rarely a good idea to modify tool-generated code. Why not just make a public class that exposes the verious resources as public?

Just make a static class that exposes all your properties publicly.

static class PublicResources
{
   public string SomeStr
   {
       get { return Resources.SomeStr; // where SomeStr is an internal resource
   }
}

Thanks for that bit of code that does work for the main app assembly, but how do i get it work for resource only assemblies, which are updated outside the project. I cant access the class because it is internal below is a web pag that tells me the following:

Listing 1: A static class is generated for all strongly-typed resources.

This class and its properties must be made public in shared, resource-only assemblies, in order for them to be accessible to other components as shown in Figure 2.

http://www.theserverside.net/articles/showarticle.tss?id=LocalizationPractices

this does not make sense because if you up date your resources the class and its properties change back to internal with the auto generated code tool.

Hope you can help in some way

Shell Output

How do I read output from another shell program (e.g. netstat --or-- dd) so I can input it into my program?
The current code I have is:
/********************
* Get the list of devices from dd.exe
********************/
System.Diagnostics.Process process1;
process1 = new System.Diagnostics.Process();

process1.EnableRaisingEvents = false;

string strCmdLine;
strCmdLine = "/C dd.exe --list > list.txt";
System.Diagnostics.Process.Start("CMD.exe",strCmdLine);
process1.Close();

My goal is to read a list of devices that it's capable of and provide a list. This program is jsut going to be a wrapper to the shell program.
Any suggestions?

Look at the ProcessStartInfo class. It has a RedirectStandardOutput property, which lets you read from the StandardOutput streamreader of the process. Then you don't have to bother with cleaning up temporary files when you are done.

Is there a way to display writeln, write, or any output from the program
in the debuger output window.
Because, I had to create an additional testForm with the richTextBox in it so I can see my print statements.

Thank you

You may use the ShowDialog() method to wait for a response and cast its return with DialogResult class.
Or in the Deactivate event of this login form write:
Activate().

Make it modal.
When you load you're authentification form, call
theAuthForm.ShowDialog(parentForm); and that's probably enought but if you are looking to have the dialog abolutely on the top of all the others application windows , try the property theAuthForm.TopMost=true.
I hope I've correctly understood your question.

Passing the values among Forms

Anonymous5-Jul-05 9:05

I have Form1 (main form) containing menues, and etc...
Then by clicking on the menu options in Form1, I invoke the children of Form1 :

private void menuNew_Click(object sender, System.EventArgs e)
{
string a = "New_Click";
Form2 fNew = new Form2(a);
fNew.MdiParent = this;
this.menuNew.Enabled = false;
fNew.Show();

}
something like that.

When I am ready to close fNew form, how do I set menuNew back to enabled.
I know you can do it prety easily using ShowDialog, but I have to do it with MdiParent settings.

Thank you

Make a public property of the Form1

public bool NewMenuEnabled
{
   set{ this.menuNew.Enabled = value; }
}

And when your MDI form is closed, go something like

((Form1)MdiParent).NewMenuEnabled = true;

One approach I woulds suggest is that your parent register with the child Closing() or the child Closed() event. Then when the application window is closing, the parent can reset the menu.

Read data from CryptoStream

kani985-Jul-05 7:37

5-Jul-05 7:37

I want to know if there is a way for me to read decrypted data from a CryptoStream and added it to a HashTable. Right now I write the decrypted data to an xml file and then read the data back in from the xml file and add it to a HashTable. I want to skip the part of writing the data to the xml file and just add it directly to the HashTable. However, the CryptoStream class does not have a ReadLine() or Peek() method. I need to be able to read one line or character at a time. Any help would be appreciated, thanks.

Re: Read data from CryptoStream

Guffa5-Jul-05 8:42

The CryptoStream is a byte stream, not a text stream. Depending on the encoding of the encrypted data, one byte might not correspond to a character. If the encoding is utf-8, for an example, some characters may use more than one byte.

You need a StreamReader to read directly from the CryptoStream to get the encoding right. Example:

StreamReader reader = new StreamReader(cryptoStream, System.Text.UTF8Encoding);

While creating C# Class Library (DLL) Using Visual Studio .NET, once we have created the dll file, then if we want to use the dll file in someother projoect then I have to add it as a reference by Project->Add reference. I was wondering if I have to do it everytime I create a new client program or just I have do it once and then in each client project/program I can call the namesapce by

using mcMath; \\ Assuming that my dll is called mcMath

You would stil have to add the reference to each application that you wrote that uses this .DLL.
