use this code
if (this.lvSDeduc.SelectedItems.count == 0)
{ MessageBox.Show("You must select something to remove before clicking the remove button.");
return;
}ListViewItem objItem = this.lvSDeduc.SelectedItems[0];
i think it will work

Try this in your button message handler:
string sSelectedItem = m_ListBox.SelectedItem.ToString();
if( sSelectedItem != null )
{
m_ListBox.Items.Remove( sSelectedItem );
}
Hope this helps

Something kind of puzzled me quite a while ago and has came back up again (just like eating KFC Chicken, taste that stuff for three days). Why exactly does it matter to declare a delegate outside a class definition instead of just declaring it inside the class?
Rocky Moore <><
|
|
|
|

Well, a delegate is a class. So, if you declare a delegate DelegateType inside a class ClassType, you will have to reference it via ClassType.DelegateType instead of just DelegateType, if you are referring to it from outside the class.
|
|
|
|
|
Yes, that is the obvious, since it is nested it must be referenced with the class it is defined in. Is that the only reason though? That is the actual results I like, since it pertains to the class I like have it contained in the class.

And you can mark it internal etc to hide to implementation. Personally I keep delegates outside types, but mark them internal.

I’m trying to scrape a site but I’m having a problem.
My program works for 4 iterations and then stops. I ported this code, line for line, over to Perl and it works fine.
I stepped through the C# code and found that it hangs on this line:
objStream = wrGETURL.GetResponse().GetResponseStream();
But it only hangs on the fifth time, it works for the first four times.
This is baffling me, so I'm hoping one of you guys can figure out what is wrong.
e") != -1)ThisOne = true;
}
}
Console.ReadLine();
}
}
}

Try an "objReader.Close();" before it goes out of scope.
(If this message is posted twice, sorry.. CP gives me all kinds of fits about posting message. It errors out about 50% of the time. Never know if it got posted until I see them actually appear.)

Thanks Rocky,
That did the trick.

Hi,
I run your code. In my first trial , after a time , it seemed to be stopped. Yes it was at index 4. Later i decided to debug your code and it worked well. Later i made it run without debugging, guess, it worked well again.
That means that there doesn't seem to be a code problem.
Cheers,
Doing something is better than doing nothing. So ... Move !

Can you tell me? Or give me some hints. Thanks a lot.

Please, any one can help
i want to display flash movies in c# forms but i cant do it.
|
|
|
|
|
there can be other means, but the simplest i can think off, is to host IE web control in your form and feed it with html which has your flash movie.
Cheers,

Dear gurus,
I am adding "\n" to a string, not working.
Do I use "Convert.ToChar(some int here?)" ?
Thanks so much

Try "\r" for a carriage return, "\n" for a newline.
|
|
|
|
|
You may have to "\r\n" because the standard DOS newline sequence is two characters '\r' followed by '\n' as opposed to the one character version used by UNIX and MACINTOSH.
|
|
|
|
|
Try with Environment.NewLine
|
|
|
|
|
Hey, you gurus are fantastic.
Both "\r\n" and Environment.NewLine work.
Appreciate it so much

Is there no way to pass an object by constant reference as you can in C++.
It doesn't seem to be possible in c#.
There must be some way of passing an object into a function and guaranteeing that the function does no change the object. This is a pretty basic and essential feature for writing robust code.

here's an example of 3 different constants in C#
VB:
<font color="blue">Public</font> <font color="blue">Const</font> int PBM_SETBKCOLOR = 0x2001;
<font color="blue">Public</font> <font color="blue">Const</font> int PBM_SETBARCOLOR = 0x409;
<font color="blue">Public</font> <font color="blue">Const</font> int WM_CLOSE = 0x10;
hope that helps.
My Signature
<font color="blue">Private void</font> ExpectingTwins(<font color="blue">string</font> twins)
{
<font color="blue">switch</font>(twins)
{
<font color="blue">Case</font> ("twins on the way"):
MessageBox.Show("for mr and mrs dynamic","twins on the way");
<font color="blue">break</font>;
}
}

I think SteveUK is talking about something like this in c++:
void foo( const string& text );
According to Programming C# by Jesse Liberty you can pass by reference but I was not able to find anything about passing by const reference:
void foo( ref string text )
{
...
}
The only ways I was able to find on passing parameters are: by-val, by-ref, and with the "out" modifier (which appears to be similar to by-ref.) Hope this helps.

This is pretty much built into .NET. The following shows you:
Foo(object o)
{
o = null;
}
Main()
{
Object o = new Object();
Foo(o);
WriteLine(o);
}
