Thank you .but I want do to our own search from my own web site. It is possible.

Yes, of course it is. You'd have to have no dynamic pages, and store all your pages in a SQL Server database. Or, you'd have to write your own search engine that indexes all your pages.

Hello everyone,
What means "the synchronizing object can double as the object it's protecting" in below statements about synchronization object choosing?
I quote the whole paragraph,
http://www.albahari.com/threading/part2.html
--------------------
Choosing the Synchronization Object
Any object visible to each of the partaking threads can be used as a synchronizing object, subject to one hard rule: it must be a reference type. It’s also highly recommended that the synchronizing object be privately scoped to the class (i.e. a private instance field) to prevent an unintentional interaction from external code locking the same object. Subject to these rules, the synchronizing object can double as the object it's protecting, such as with the list field below:
class ThreadSafe {
List <string> list = new List <string>();
void Test() {
lock (list) {
list.Add ("Item 1");
...
--------------------
thanks in advance,
George

You have a synchronising object, the object used in the lock statement. You also have the object you are protecting with the lock. The statement means that the object you use in the lock statement can be the same as the object you are protecting.
Does that help?

Thanks Colin!
I think you metn the "list" object is the synchronising object. But what do you mean "the object you are protecting with the lock", you mean also the list obejct which we are going to make it thread-safe?

George

In the example the "list" object is the synchronising object.

In the example, yes, it will be the list object also.
The example was showing that the object used in the lock, the list, can be the same as the object that is being protected, which is again the list.

Hello everyone,
From the sample,
http://www.albahari.com/threading/part2.html
Do you know what means "A thread can block only on the first, or outermost lock."?
I quote the related context below as well.
--------------------
Nested Locking
A thread can repeatedly lock the same object, either via multiple calls to Monitor.Enter, or via nested lock statements. The object is then unlocked when a corresponding number of Monitor.Exit statements have executed, or the outermost lock statement has exited. This allows for the most natural semantics when one method calls another as follows:
static object x = new object();
static void Main() {
lock (x) {
Console.WriteLine ("I have the lock");
Nest();
Console.WriteLine ("I still have the lock");
}
Here the lock is released.
}
static void Nest() {
lock (x) {
...
}
Released the lock? Not quite!
}
A thread can block only on the first, or outermost lock.
--------------------
thanks in advance,
George

It means that when it encounters the first lock (or outermost lock) the thread blocks others from accessing the object that is locked.
An individual thread can lock an object as many times as it likes, but it only locks on the first occurrence.

Thanks Colin,
Two more comments,
1.
Colin Angus Mackay wrote: It means that when it encounters the first lock (or outermost lock) the thread blocks others from accessing the object that is locked.
Even if the thread can not acquire the outermost lock, it will block other thread from accessing the lock object to try to lock?

It is a typo, "only locks on the first occurrence" should be "only blocks on the first occurrence"?

It hast to aquire the lock first. If it can't aquire the lock, it can't block.

Yes. You are correct.

Hi
how to pass textbox value from one form to other form in window application
+c# .If any one knows this help me with code i'm new to window application
Thanks and regards

Lots of different ways, but you could expose a property on one of the forms like:
public string TheValue
{
get { return theTextBox.Text; }
set { theTextBox.Text = value; }
}
Your other form can set TheValue using code like chee:
form2.TheValue = "stuff";
form2 would be an instance of your "other form" which has already been created, of course.
- S
50 cups of coffee and you know it's on!
|
|
|
|
|
You can also pass it to a session variable and u can retrive the values in the form u needed.
|
|
|
|
|
You're very confused. Forms apps do not have session variables.

Hi
very very easy
there is 2 ways pass the value one form to a nother forms.
1.Properties
2.Constructor params
In my point of 2ndis good because of when make cons we , just create overload cons and pass the varible to that.
variable is textbox value

Hello.
I am developing a program where I have some textboxes and forward and previous buttons.
I also have a txt file. I want to read from my txt file and then write to my textbox.
My txt file looks like this:
19 1 "Yeti" 30 900 0 105 110 37 0 150 37 2 17 4 6 400 2000 10 2 180 14 6 0 0 3 0 0<br />
20 1 "Elite Yeti" 36 1200 0 120 125 50 0 180 43 3 0 1 6 400 1400 10 2 180 14 6 0 1 4 1 1<br />
21 1 "Assassin" 26 800 0 95 100 33 0 130 33 2 0 1 7 400 2000 10 2 180 14 6 0 0 0 0 0<br />
22 1 "Ice Monster" 22 650 0 80 85 27 0 110 27 2 7 1 5 400 2000 10 2 170 14 6 0 0 3 0 0<br />
23 1 "Hommerd" 24 700 0 85 90 29 0 120 29 3 0 1 5 400 1600 10 2 170 14 6 0 0 3 0 0<br />
24 1 "Worm" 20 600 0 75 80 25 0 100 25 3 0 1 4 400 1600 10 2 160 14 6 0 0 2 0 0<br />
25 1 "Ice Queen" 52 4000 0 155 165 90 0 260 76 3 11 4 7 400 1400 50 2 180 14 3 0 4 5 4 4
I want it to read one line and then for example set Yeti and 19 into a textbox
When you push forward it reads elite yeti and 20
But I don't know how to do
I am assuming I need space as a separator and then use like var[3] where 3 is the third word.
A little like in mirc where you can write
$gettok(one two three, 32, 3) where it picks the 3 word with the separator space (32)
But when it gets to the code and not the idea im kinda stuck. Any ideas?
Im using Visual C# 2008 Express Edition

the split method on the string class would usually do it, but because you have spaces in words, you need to either use split them rejoin based on quotes, or write your own parser.

I have been ripping my hair out because I cant find a solution.
I got it all working, but now I must format more text
I got a new text that has sections like this:
<br />
1<br />
0 33 10 85 162 95 168 -1 5
1 29 30 40 113 45 116 -1 3
2 41 5 126 160 125 161 -1 2
3 38 5 106 161 111 160 -1 2
4 38 5 106 161 111 160 -1 2
6 38 5 106 161 111 160 -1 2
7 38 5 106 161 111 160 -1 2
14 38 5 106 161 111 160 -1 2
end<br />
0<br />
275 33 10 85 162 95 168 -1 5
275 29 30 40 113 45 116 -1 3
275 41 5 126 160 125 161 -1 2
275 38 5 106 161 111 160 -1 2
end
Now I changed my script so it reads the values from this script, and I changed the forward button so it jumps into new sections
But I just cant seem to figure out how to jump back to a section
This is the code that I use to go foward into a section:
if (pieces[0] == "end")<br />
{<br />
curRec += 2;<br />
displayLine(curRec);<br />
}<br />
else<br />
{
Here is all my code:
public void displayLine(int linenumber)<br />
{<br />
if ((linenumber >= 0) && (linenumber < lines.Count))<br />
{<br />
<br />
String line = (String)lines[linenumber];<br />
<br />
String[] pieces = line.Split('\t');<br />
<br />
if (pieces[0] == "end")<br />
{<br />
curRec += 2;<br />
displayLine(curRec);<br />
}<br />
else<br />
{<br />
txtID.Text = pieces[0];<br />
txtMap.Text = pieces[1];<br />
txtMoving.Text = pieces[2];<br />
txtXStart.Text = pieces[3];<br />
txtYStart.Text = pieces[4];<br />
txtXEnd.Text = pieces[5];<br />
txtYEnd.Text = pieces[6];<br />
txtDirection.Text = pieces[7];<br />
txtCount.Text = pieces[8];<br />
txtComment.Text = pieces[9];<br />
mobImage.ImageLocation = "D:/images/" + pieces[0] + ".jpg";<br />
}<br />
}<br />
<br />
}<br />
<br />
ArrayList lines = new ArrayList(100);<br />
<br />
int curRec = 0;<br />
<br />
public void Form1_Load(object sender, EventArgs e)<br />
{<br />
StreamReader f = new StreamReader(new FileStream(@"D:\monstersetbase.txt", FileMode.Open));<br />
<br />
String curLine;<br />
<br />
while ((curLine = f.ReadLine()) != null)<br />
{<br />
lines.Add(curLine);<br />
}<br />
<br />
f.Close();<br />
<br />
curRec += 1;<br />
<br />
displayLine(curRec);<br />
}<br />
<br />
private void nxtButton_Click_1(object sender, EventArgs e)<br />
{<br />
if (curRec < lines.Count - 1)<br />
{<br />
curRec += 1;<br />
displayLine(curRec);<br />
prvButton.Enabled = true;<br />
}<br />
}<br />
<br />
private void prvButton_Click_1(object sender, EventArgs e)<br />
{<br />
if (curRec == 2)<br />
{<br />
prvButton.Enabled = false;<br />
}<br />
if (curRec > 0)<br />
{<br />
curRec -= 1;<br />
displayLine(curRec);<br />
}<br />
}
