"Synchronization in Threads
When we have multiple threads that share data, we need to provide synchronized access to the data. We have to deal with synchronization issues related to concurrent access to variables and objects accessible by multiple threads at the same time. This is controlled by giving one thread a chance to acquire a lock on the shared resource at a time. We can think it like a box where the object is available and only one thread can enter into and the other thread is waiting outside the box until the previous one comes out."
As quoted from a Code Project Article[^].

hi, god day,,,
i tried to run your corrected code but it will still give the same error
"Cross-thread operation not valid: Control 'TxtBoxMsg' accessed from a thread other than the thread it was created on."

your suggested code did not run, however i still want to thank you for your effort done. your code really help a lot to solve my problem... I made a little adjustment on your corrected code....
again, thank you very much
using System;
using System.Windows.Forms;

{
public partial class WebBrowser : Form
{
public delegate void DisplayHandler(string stringMessage);
//public event DisplayMessage;

{
InitializeComponent();
}

private SocketServer mySocket;
private void WebBrowser_Load(object sender, EventArgs e)
{
threadSocket = new Thread(StartSocket);
threadSocket.Start();
}
public void StartSocket()
{
mySocket = new SocketServer();
mySocket.SocketDataArrival += ShowDataArrival;
mySocket.InititateServer();
}
public void DisplayMessage(string stringMessage)
{
this.TxtBoxMsg.Text = stringMessage;
}
void ShowDataArrival(object a, SocketServerArgs e)
{
//DisplayHandler d = DisplayMessage;
//d.Invoke(e.Message);
DisplayHandler d = new DisplayHandler(DisplayMessage);
this.TxtBoxMsg.Invoke(d, new object[] { e.Message });
}
}

I am writing a a piece of software that includes a library that plays sounds that I would like to prevent.
Is there a way in .NET to mute my current process?
Thanks,
S.

|

|

No. Your code has to just not play sounds. You cannot mute individual processes.

As far as I remember this is possible on Vista. I'm not sure there an API call for that, though.

Maybe you can replace the relevant sound files with a sound file that is 0 seconds of silence or something like that?
just be careful if it's a commercial thing with an evil license that promises eternal doom to people who try to mod it

Hi Team,
The required functional logic is to convert audio formats VOX file to MP3 format.What exactly I m looking for a logic to fullfill the above functionality.
Could anybody help me out from this scenario.
Thanks & Regards

not done that before but what i suggest is you find out how both file formats are stored i.e. the raw data of each file.
then write an algorithm to write the mp3 file in its correct format based on the values you read from the VOX file

I'm writing a Word add-in in .NET 3.5 and have some user settings in my app.config.
When installed at a user, where are these settings stored?
When the user save a setting, it's not stored in the .config file where the DLL is, and I can not find it anywhere else...
Anyone who knows?

User settings are written to isolated storage, e.g. C:\Documents and Settings\Administrator\Local Settings\Application
Data\My Company\My Word Addin\1.1.0.0"
|

|
|
|
Thanks.
I'm using Vista though, and "local settings" is a redirect and no matter what I do I'm denied access 
Any ideas?

Under Vista, it's in the C:\ProgramData\username folder. The ProgramData folder is hidden, so you'll have to "show hidden folders and files" in Explorer to see it.

Hello,
I have a global connection object.
I have few methods, each of them do database operations, each of the method use one connection object. In order to use the transactions do I need to use a global command object too?
class operation
{
OracleConnection oCon = new OracleConnection();
MethoodA()
MethoodB()
MethoodC()
}
MethodA()
{
Command object is used for database operation
}
Will this Command Object will also be a global variable access to all the Methods?
Regards,
Pavas

Why global connection?
Just have the methods create the connection as an when needed
|
|
|
|
|
Its a Windows service. And it does lot of operation hence I created a global connection.
Also I need to implement the Transactions between different methods which do different operation on database.
Please suggest what can be the good approach
Regards,
Pavas

ok i see why you went for a global then, cant say if that is still the best option but i dont know what exactly you are doing.
What difference do the methods have, do they need different commands?
if so you would change the global command with each method, so may as well just create the command you need in the method and pass to connection
