Reason why i'm asking for an example is that I already tried my own method of locking, but my data still got corrupted.
This is the type of code I used...
List<int[,]> largeData;
List<int[]> referenceList;
int answer;
Parallel.Foreach<int[]>(referenceList, refArray=>
{
foreach(int[,] largeMatrix in largeData)
{
lock(largeMatrix)
{
answer = 0;
foreach(int ref in refArray)
{
answer += largeMatrix[ref];
}
}
}
});
I also tried locking the "refArray", but in either case, I got the wrong results...

I know I'm repeating myself, however to get maximum performance, you must restructure your data and avoid all locks as they cost CPU cycles and reduce parallelism. Hence, use partial sums that don't interfere with each other, and in the end add them all together once.

I only read code that is properly indented, and rendered in a non-proportional font; hint: use PRE tags in forum messages

Hi, thanks, but I'm not sure I quite understand
How would I restructure my data, and how do you propose I use partial sums?

Is it possible to embed an image to a HTML-formatted e-mail? I don’t want to create a link (with <img src=”http://...”> ).
I’m creating a newsletter mail application.

You can embed it, but it won't be viewable in that format ( and it will be bigger ). You can attach it, but it won't be visible unless a mail program chooses to show it, and you sure won't get to say where the image is visible.

I have a hardware connected to the usb which communicates by sending the data.When i will start the application and hardware as a fresh it will work fine.But when i will stop my hardware and run it again it will throw me a exception handle stating that the Access denied for COM1: as you dont have proper rights to the resource.But when i remove the USB plug and re connects my application to the hardware it will start working.
Do anyone know how to reset or re intiallize or reconnect the usb to hardware programitically...?

How about closing it ?
SerialPort serialPort = new SerialPort(...);
serialPort.Open();
...
...
...
serialPort.Close(); // <- close the connection
serialPort.Dispose(); // <- dispose resources in serialPort, use it if you close your application

I tried all the stuff u mentioned, but it didnt work.I need to unplug and plug again to make it work.So i am looking is there any way to unplug problematically.

Probably you are using a thread, and the thread is still active ?
You must end the thread.
What happened if you close your application and start it again ?
|
|
|
|
|
No I am not using any thread.Even i close and run the applicatio i face the same problem.As i mentioned i need to remove and place the cable again to re communicate the data.

That means, there are something wrong with your USB-COM adapter.
Try to install the newest driver. Probably it's a bug in driver.
|
|
|
|
|
I have updated with the latest drivers and still i face the same issue.
Unfortunately it is not working with any other hardware also.
|
|
|
|

Check your system, probably there are some process that watch your COM Port.
If you say "Unfortunately it is not working with any other hardware also",
that means something wrong in your system. That's not .NET problem.

I have a window application. When I turn off the computer while this app is running I get some error window with caption:
.Net-BroadcastEventWindow.2.0.0. end the program tries to close the app. after awhile I get a message that the app is not responding and the computer does not turn off automaticly but just when I close this message.
What does it mean? and How can I solve this?
Thanks.

Why don't you just capture WM_QUERYENDSESSION and respond to it.

I'd guess the SQL or database forums are appropriate, you posted SQL.

You can set To Address , Subject And Message Body like this

Hi,
Thank you for the reply..This mailto tag opens a new mail..I need to have the tag in an email..If I click the link ,I want the contents of that mail to be placed in new mail..similar to normal email reply action..
If I use mailto, how will I get the contents of that mail and place that in new one....

You want for the email you send to have a link to send back a new email ? The answer is the same, it just won't work unless the mail program is showing HTML.
