Hi buddies,
If more than one thread may enter .NET collections (ArrayList, NameObjectCollectionBase, ...) Add() methods should I enclose the code that calls Add() in a lock statement?
Also can you tell me a general rule to underestand when I SHOULD call some method only inside a lock statement in a multi-threaded app?
Thank you so much,
- Mohammad

From MSDN documentation on ArrayList:
"Public static members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe."
As Add() is an instance member, it's not guaranteed to be thread safe, so you should use lock.
The documentation should contain thread safety information for all classes.

Hi
I have a Sql Server datebase in our company on a Server.
I want to read the server Time from the clients and i don't want users can change their computer time .
but I don't know how can i do it.please help me
|
|
|
|
|
With SQL Server, you can run the following select statement to get the time:
SELECT GETDATE()
To set the time, read the source code of the NTPClient class from the article SNTP Client in C#.
To prevent users from changing the clock, investigate the "Change the system time" policy for users in your domain/local computers.

I have an problem in converting the desktop coding in Windows Serice. all the code was translated successfully but the problem i m facing in below code of line when i trying to write this line of code in wnidows service its getting error in Invoke method, its compulsory for me to call this (INVOKE)method cause the parameter inside this are delagate and collection of parameters that i have to pass these in any case, so can any one tell me what should i do to access this INVOKE method in windows service.
Code: this.Invoke(new PingStartedEventHandler(netMon_PingStarted), new object[] { sender, e });
|
|
|
|
|
I presume you're moving this code from a Windows application? If that's true, then the Invoke you are talking about would be Control.Invoke, which I *think* won't be available in a Windows service.
If you're not updating UI elements, I guess you can safely skip the Invoke and directly call the method using the delegate.
PingStartedEventHandler pe = new PingStartedEventHandler(netMon_PingStarted);
pe(sender, e);
Regards
Senthil

hi everybody,
I would like to ask a question here.

Sincerely,

Depends on the context. Static functions are useful for factory methods like Create, which create and return appropriate objects.
dinh van hai wrote: How are they disadvantage ?
Static functions are like global functions, only that their scope is restricted to the class. So too many static functions and the class then becomes a dumping ground where you keep adding functions that don't fit elsewhere.
dinh van hai wrote: Shuold I use many static function in a program ?
Of course you can. You can take the system defined static functions, like File.Create as a starting point.

Senthil

how do static functions affect the performence and memory of our program ?
|
|
|
|
|
If the function doesn't use any data from the instance of the class, it should be static, so that you don't have to create an object just to call the function.
Declaring a function as static also supplies the information that the function is self-contained and doesn't need any data from an object.

Hi together!
I'm currently searching a way to get a Process by it's window title, not by it's classname...
in following code, the GameName would be, e.g. "sol" (means Processname of game "Solitär")
<br />
static ProcessMemoryReaderLib.ProcessMemoryReader pReader;<br />
static Process[] myProcesses;<br />
<br />
public static void InitRWCode(string GameName)<br />
{<br />
pReader = new ProcessMemoryReaderLib.ProcessMemoryReader();<br />
myProcesses = Process.GetProcessesByName(GameName);<br />
}<br />
that's the code i'm currently using...
but i'm looking for something like that:
in this case GameName would be "Solitär" instead of "sol"
<br />
static ProcessMemoryReaderLib.ProcessMemoryReader pReader;<br />
static Process[] myProcesses;<br />
<br />
public static void InitRWCode(string GameName)<br />
{<br />
pReader = new ProcessMemoryReaderLib.ProcessMemoryReader();<br />
myProcesses = Process.GetProcessesByWindowTitle(GameName);<br />
}<br />
Has someone an idea 
I've already tried the GetWindowThreadProcessId together with the FindWindow, but it returns the wrong ID...
Thx for any suggestions!!!

Hi! Thanks for your reply!
Yes of course - and that's the problem. In my case it's too slow - i'm working with hotkeys. And every time a hotkey is pressed, it needs to get the excact handle of the window. So every time GetProcesses is called. And that's very slow. So i have to get the window handle directly by it's window name - that's a lot faster!!! than GetProcesses!!!. So if anyone have a suggestion... Please let me know...
Thx!

Hi, I'm using SgmlReader to obtain the XML data from a web page and I have an IndexOutOfRangeException exception when I execute the Load method from the XmlDocument class.
I had no problems before but now it started to happen.
Here is part of the code:
string path = @"C:\....";
StreamWriter w = new StreamWriter(path+"file.txt",false,System.Text.Encoding.Unicode);
SgmlReader r = new SgmlReader();
r.DocType = "HTML";
r.Href = "http://www.webpage.com/page.htm";
XmlDocument xml = new XmlDocument();
xml.Load(r); <-- Here the exception is threw.
