Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]

You can do somesing like this:
private string login = "test@ukr.net";
private string password = "test";
private string smtp_host = "smtp.ukr.net";
int port = 465;
public Mailer()
{
System.Net.Mail.SmtpClient mysmtp = new SmtpClient();
mysmtp.Host = smtp_host;
mysmtp.Port = port;
mysmtp.EnableSsl = true;
mysmtp.Credentials = new System.Net.NetworkCredential(login, password);
MailAddress from = new MailAddress("test@ukr.net", "user anonimus =)");
MailAddress to = new MailAddress("to@mathcentre.com.ua");
MailMessage msg = new MailMessage(from, to);
msg.Subject = "programm test";
msg.Body = "test!!!!!!!!!\n see ya!";
mysmtp.Send(msg); // this code works but I dont now how use certificates that
//used by some mail-servers =(
}

Hi everybody!
just wanted to ask a short question:
I have a property, that should be (externally) threadsafe. Is this good coding style, or do you have a better solution?
class Manager
{
private object locker = new object();
private MyType threadSafeProperty = new MyType();
public MyType ThreadSafeProperty
{
get { lock (locker) { return threadSafeProperty; } }
set { lock (locker) { threadSafeProperty = value; } }
}
}
Thank you, Phil
I won’t not use no double negatives.

AFAIK, "lock" is not recomended since it can result in permanent lockups of an object for ever.
Monitor.TryEnter does the same but takes an argument specifying timeout interval.
Also, the locker object should be readonly.
|

This will not work if your intent is to synchronize access to the MyType instance. You are only holding the lock while getting the reference to the instance. You then return the instance to the calling code which may then use it without synchronization.
The solution depends on what the calling code does with the MyType instance. You could expose a synchronization object in the Manager class, but that is open to abuse. Or you could add methods for manipulating the instance through the Manager class and use locks in those methods. YMMV.

Thank you for you answer Nick.
That was actually why asked this, I had a bad feeling about that 
MyType is some kind of generic List. I wanted to ensure that I had exclusive access to the list as long as I was manipulating it.
Stupid idea now
I will expose the lock and acquire it as long as I am manipulating the list.

Philip. Your concept of locking an object while returning a reference to it as a means of synchronization indicates you are far from understanding the fundamental concepts of synchronization. I strongly urge you to study the subject more before attempting any implementation requiring thread synchronization.

I'll do that.

Then you will do well.
If it helps you, back when I started trying to understand mulit-threading I found Jeffery Richters book Advanced Windows[^] extremely helpful. Keep in mind it was the first edition so no guarantees the new one is the same.

}
can you tell me how i get the number of row about findRow thank you
|

do you mean the index of the row that was found?
if so use this line of code where your blank comment is...
int rowNum = thisDataSet.Tables["SchoolMoney"].Rows.IndexOf(findRow);

Hi,
How can i serilize and deserilize a MouseEventArgs?
Thankyou,
YPKI
|
|
|
|
|
You can't, it's not serializable.
You can create a new serializable class that holds all the property you need, populate them starting from the MouseEventArgs instance you want to save and then serialize it.
BTW, don't double-post.
|
|
|
|
|
You would have be better changing the subject of your original post to describe the problem instead of reposting.
EventArgs is marked as Serializable but not MouseEventArgs.
You can recreate the MouseEventArgs and mark your version serializable - something like:
[Serializable]
public class MyMouseEventArgs :EventArgs
{
public MyMouseEventArgs(MouseButtons button, int clicks, int x, int y, int delta)
{
_Button = button;
_Clicks = clicks;
_X = x;
_Y = y;
_Delta = delta;
}
private MouseButtons _Button;
private int _Clicks;
private int _Delta;
private int _X;
private int _Y;
public MouseButtons Button { get { return _Button; } }
public int Clicks { get { return _Clicks; } }
public int Delta { get { return _Delta; } }
public Point Location { get { return new Point(_X, _Y); } }
public int X { get { return _X; } }
public int Y { get { return _Y; } }
public static implicit operator MyMouseEventArgs(MouseEventArgs e)
{
return new MyMouseEventArgs(e.Button, e.Clicks, e.X, e.Y, e.Delta);
}
public static implicit operator MouseEventArgs(MyMouseEventArgs e)
{
return new MouseEventArgs(e.Button, e.Clicks, e.X, e.Y, e.Delta);
}
}
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Visual Basic is not used by normal people so we're not covering it here. (Uncyclopedia)

|

Is there some logic\reason as to why MouseEventArgs can't be serialized? Thx
|
|
|
|
|
The reason is it was never marked as Serializable by Microsoft. The logic behind that... I have no idea, you would have to ask them.
|
|
|
|
|
Only classes that have an empty constructor can be serialized.

|
|
|
|
Yeah.... I copied the source code, added an empty constructor, and serialized it.

Hi all,
Let’s discuss and share your knowledge on this question!!
I am sure most of the member having this question in their mind and as many as members knows the answer for this!!
Mean while, you can also ask your queries to other on same topic!!!

By default, parameters are passed by value.
Click me[^]

Groan.. I know where you're coming from - for reference types, references to objects are passed by value by default. "Passed by reference" is not entirely accurate, but it describes the object sharing aspect well.
