Assign Mutex to each Thread

May 25, 2013, 8:18 am

≫ Next: windows service mouse mileage

≪ Previous: c# array

Hello,

I have a function, and i would like to let a list/array of Threads run parallel in it (inorder to protect critical sections in it).

I thought I'd create List<Mutex> and assign each one to a different Thread:
for( int i =0; i<10; i++)

{ arrmutex[i] = new mutex(); }

and in the function i would like to lock with a arrmutex.elementAt(someThread).waitOne() -> a specific variable

It tells me that i cannot do that cause my mutex list is not initialize, AND, the lock wouldn't work..

Can you please help me figure out, how to initialize a list/array of mutexes?

and how to assign each thread a mutex?

Thanks,

≪ Previous: windows service mouse mileage

Lets say you have 10 threads, in one function and you want to maximize parallelity between them, what is the best way to do that:

1. with 10 mutexes, assign each mutex to a thread?
2. with semaphore (0, 10) ?
3. with array/list of mutexes?

What would you do?

Thanks,

Timespan between two events

May 26, 2013, 9:01 am

≫ Next: convert audio to text in .net

≪ Previous: C# Language Extensions

I receive a message from serial port that is passed to a variable once every few seconds. The message is generated by a microprocessor and it is basically a simple string containing "1/r" which represent one complete turn of a motor (every time a microswitch is pressed, the micro prints "1/r) on the serial port). In order to show in a text box the revolution per minute of such motor, based on the time interval between the update of the variable, I would like to implement a timespan method. I should therefore obtain the time elapsed between the start and the end of a turn and return the result for further actions to the original method.

This is what I have done so far but does not work:

publicvoid CalcolaRPM (string giriRicevuti, outdouble RPM)

{

Stopwatch stopWatch = newStopwatch();

stopWatch.Start();

{

if (giriRicevuti == "1/r")

{

stopWatch.Stop();

}

double elapsedT = stopWatch.ElapsedMilliseconds;

stopWatch.Restart();

RPM = elapsedT;

giriRicevuti = "";

}

The result I get is 0.0, how can I get the time in milliseconds between updates of the variable "giriRicevuti"?

Hi

I have 3 related Dropdownlist in me Edit Form

I'm using the code below to bind the Dropdownlist but it will retrive the full list without the selected value saved and if i'm making a selected statment it will just retrive the selected value.

the dropdownlist is linked to other one so if the Category been saved as "Art" the Subject should retrive the saved Item the user selected earlier with the rest items for update purpose .

private void BindDrp_CAT()
{

using (SqlConnection con = new SqlConnection(myconn))

if (!IsPostBack)
{

SqlCommand com = new SqlCommand("select distinct Cat_name from tblCategory order by Cat_name ", con);

SqlDataReader dr;
con.Open();

Drp_CAT.Items.Clear();

dr = com.ExecuteReader();
while (dr.Read())
{
Drp_CAT.Items.Add(new ListItem(dr[0].ToString()));

}
con.Close();

}

}
