The stopwatch class calls QueryPerformanceCounter, and that is about as low resolution you can get. You can use the multimedia timer too for a resolution of 1ms, and much less latency.

I think that you are experiencing that a different process is using it's entire time slot before your process gets the control back.
When the request is sent and you are waiting for the response, it's most likely doing a Thread.Sleep(0) to give up the rest of each time slot (as there is no reson to check for a response 100000000 times a second). Most of the time all other processes are also waiting for something, so you will get the control back within a few ms or so, but if some other process is doing a lot of work it can take longer before you can check for a response again.
What you are measuring is not how long time it actually takes to get a response, but how long time it takes until your program notices the response. If you want to measure the actual response time you have to do it in a different way, like hooking up something in the IP stack.
Despite everything, the person most likely to be fooling you next is yourself.

Am trying to make the label's text to the current time, but not using the 'static' DateTime.Now property which I tried to use lately.
How can I go about it.Please help.

Use BackGroundWroker Process (i.e. a different thread) to update the time on label after every 1 sec(or whatever interval you like)

You could use the Timer class, which is simpler than explicitly creating another process:
protected Timer tim = new Timer();
...
tim.Tick += new EventHandler(tim_Tick);
tim.Interval = timerInterval;
...
private void tim_Tick(object sender, EventArgs e)
{
}

avoid using threads to update your gui , insted use events .
also you can use DateTime.Now to get the time

I have threads update my GUI all the time, but they have to be done properly.
I don't see how an event would help avoid using a thread.

System.Nvarchar does not exist... does anyone know how to do this?
bulkCopy.WriteToServer throws an exception because it cannot put a string into nvarchar...
dc.DataType = System.Type.GetType("System.Nvarchar");

Probably his MySQL or Oracle book

The DataType should be System.String.
|
|
|
|
|
try this:
SqlDbType.NVarChar

System.String and SqlDbType.NVarChar , doesn't work it gives exception.

Hello
I'm currently using SMTP to send mail with attachement from my csharp app
But I also need to let the user add some coments, so the best will be to send the mail via the mail client
I see that mailto: do not allow to sent attachement
I'm looking around Mapi but I do not find any relevant help
Do someone have a suggestion for me ?
Thank you very much
|

If you're using SMTP, why can't you simply add a small window to your project where user can add his/hers comments?
|
|
|
|
|
Thank you Mika
But since it might be possible to send using MAPI I want to find out how !
|
|
|
|
|
|
|
I'm already using SMTP !!

In my application,i have changed the color of text(SyntaxHighLighting), it is working fine,But whenever any one press Ctrl+Z, it undo-operations on my highlighting operations(The most recent operation).
For the solution of this problem:
I have used ClearUndo() but it clears whole undo stack while in the description of this function wrote,clear most recently undo operation.
If you have any solution of this problem,Please suggest().
Can we suspend/Disable/Off Undo or any other way to do the things?

Nope - you can't suspend it. What you could do is roll your own undo manager, but this would not be trivial. Alternatively, you can always reapply the syntax highlighting immediately following the undo operation.
|
|
|
|
|
If I have to Undo the Text that was typed just before Syntax Highlight, than we will never able to do the same.
|
|
|
|
|
You will have to re-syntaxhighlight the line, and possibly lines before that. Have fun
