Why not just send the strings directly, without assigning to a variable?
Sounds like somebody's got a case of the Mondays

ahahahahahah 
that's right, that would solve it. 
But that example is just an illustration of my problem. The actual code gets the contents from somewhere else dynamically, and it doesn't display a message box, it does something else... this was just to simplify. I actually solved this by moving the value holder inside the context, and this way, a new reference is always created.

Exactly... that is why Dave asked you for more specific code. Clearly, you would have thought of this if it solved your problem; however, in your example this is a valid solution. Try to be slightly more specific in your problem statement so we can give "real" feedback instead of having to guess what the problem is. Glad you got it working,

Ok... the thing is... I had solved it since I posted the first message here.. I said it even... I only spoke about the positioning of the variable and the association to runtime delegate.
This is que only thing that I questioned:
Kensho wrote: Now... can anyone explain me why does this happen? The delegate uses the reference instead of the value?
delegate... value... I don't understand why the big fuss over a simple question.
But nevermind... I already got my answer... maybe someone can pick this up and find it useful, as a simple piece of information, as it is.

One word : closures. A closure captures the value of a variable in its lexical scope.
Your event handlers are anonymous functions which capture the local variable text. Behind the scenes, the compiler generates a new class with the captured variable as a member and rewires the event handler so that it calls a method on the generated class. That class then uses the member variable's value to fill in for the captured variable.
The compiler updates the generated class instances with the value of captured variables as long as the captured variables are in scope. In your case, text was declared outside the scope of both if blocks, so the compiler dutifully updated the value of the variable when you changed it inside the second if block.
Just to make things clear, this is not done only for reference types (like string).
delegate void Func();
static void Main()
{
Func[] f = new Func[10];
for (int i = 0; i < 10; ++i)
{
f[i] = delegate { Console.WriteLine(i); };
}
foreach (Func func in f)
{
func();
}
}
This will print 10 all ten times.

Exactly!
Now that's an answer. Thank you.

Do you want to?:
1. Highlight the text that is currently in the text box as the user enters the control.
2. Set the background color of the text box as the user enters\exits the control.
If the answer is 1:
Handle the Enter event for the textbox and then call textbox.SelectAll();
If the answer is 2:
Handle the Enter event for the textbox and set the textboxes Appearance.BackColor property.
Handle the Leave event and set this same property back to its original value.
If its neither then you will need to explain again what you were asking.
I hope this helps.

you can use Textbox.Focus() methods and Textbox Leave Events and Changes the background color according it !!!

Hi all,

Read a text file and display them in a list view. Simply as line by line. I can read the file and get line by line there easily. My question is how to display them.
Any tutorial you guys know that I can get a better start.

Yes I do,
But I have one question now. I read a file and found those lines to put into list view. A line consist of four words and in between each word there is a tab character. For tabs, on list view display some annoying characters. I put a message box and test at the time I got the line of text. It's ok, no printed and tabs.
How can I avoid it.
I appreciate your help all the time...

value.Replace('\t',' ');
This replaces all occurences of tabs with a space.

Thanks, but what I have done is that, use tab as a delimiter and get substring from the original string.

AFAIK, it won't display. A service is supposed to run without any user interaction. I.E. no System.Windows.Forms. I think you can have the tray icon, but no context menu. Maybe someone will verify this. What I think you will have to do is have your service start a process that is nothing but a tray icon, with the context menu(if that's what you want), and then have that application communicate with the service.

You can't easily do it. It's as simple as that. If you could, this would represent a huge security hole whereby you could get really malicious with the user without them knowing. There's a reason that people switch off cookies and it's really bad practice to try to circumvent that.

Yes you do have to ask. Period.

How can I show table into 2 columns - one half of data in the first and other half in the second column in Crystal Report?
In Visual Studio Local Report it's accomplished by setting Report's Body Columns on 2.
Example:
||| => ||| |||
||| => ||| |||
||| => ||| |||

Thanks for any help.

Hi
I have a sql statement which is in my c# code.
How would I write the following though
Select * from table where field contains a certain value
e.g. select these values from the table
v1106~066
v1106~066_01
where as at the moment it just selects:
v1106~066_01
my current sql statement is select..... LIKE '" + s_number + "'" +
s_number is the value v1106~066_01
thanks!!!
hope it makes sense

|

sorted it:
"'+ session_room_code + "%'"+
|
|
|
|

In order to match against multiple records, you need to apply the wildcard characters in your search. In other words, you need to use v1106~066% to retrieve the two records. A couple of thoughts though.
1. You shouldn't retrieve all of the columns using *. That's just lazy coding and should be avoided at all costs.
2. You've left yourself wide open to a Sql Injection attack. Read this[^] article.
