Well, you can use the ListView.SelectedItems property to retrieve a collection of all items that are currently selected. Iterate over the returned collection and for each item delete the respective file by using classes from System.IO namespace (if you really want to delete on the file system) and finally remove the item from the list view via ListView.Items.Remove method.

what is escape sequencing? how is it useful in c#/Asp.net 2.0?
thank you
|

An escape sequence is a combination of characters that has a special meaning. The term escape sequence comes from the sequences used with things like a line printer, where the first character is the ESC character.
Escape sequences are used for example in URLs, HTML code, XML code, SQL strings, Javascript strings and C# strings. They are used to insert special characters that can't normally be written.
In URLs the escape character is %, in HTML and XML it is &, in SQL strings it is ' or \ depending on database, in Javascript strings and C# strings it is \.
Some common escape sequences:
C# strings:
\" = quote character
\r = carrege return (character code 13)
\n = line feed (character code 10)
HTML:
& = & character
" = " character
< = < character
> = > character
URL:
%26 = & character
%3f = ? character
%2f = / character
%20 = space character
%25 = % character

"\u000a" and '\u000a' however those are in unicode. To get the ascii value you would need to use an Ascii Encoder and grab the bytes but why bother, just write 0xa to the stream.

I don't think that's going to fly for a lot of circumstances.

The paradox of your question is that you are wanting to use a generic container for content which cannot necessarily be processed generically.

watch out there, using "urgent in your post subject is not a good idea

Does anyone has positive expirience with comboboxes that can be bound to nullable properties? I'm developing application in which I often bind ComboBox to DataColumn (with AllowDBNull set to true) of typed DataSet. It works fine but if user selects item it can no longer say - hey set that to Null.
Ideal solution would be something like new DateTimePicker - having ShowCheckBox property and if it is Checked get selected Date, if it is Unchecked get DBNull.Value. (see image below I referenced from one of CodeProject articles)
So any suggestions or I am damned to make control myself?

i had the same problem a few months ago and i also hadn't found a good solution. my workaround was a union including my datatable and an "empty" datarow.

Funny thing is that MS also suggests this practice:
http://www.windowsforms.net/FAQs/default.aspx?PageID=2&ItemID=722&CategoryID=3&tabindex=3
But again it can't be too hard to make something like DateTimePicker's ShowCheckBox.

Hi Guys,
Im fairly new to the world of C#.... Im in the process of building a web form that uploads a CSV file to my server from there it will have to read the file and store the output in an Array. Ive read through the countless tutorials on various sites around the place, but im finding this a little tricky. so all i need is a simple class that can read the contents of a CSV and store it in an array. can anyone of you fine c# gurus assist in this relatively simple app ?
cheers

Hi,
Easy way is this;
using System.IO;
.
.
public string[][] readCSV(string fileName)
{
StreamReader read = new StreamReader(fileName)
string [][] content = new string[100][100];
int row =0;
for(string line = read.ReadLine();line!=null;line=read.readline())
{
content[row][0] = line.Split(',');
row++;
}
return content;
}
Please let me know if it helps

How to get icons in GUI
Keshav Kamat 
India
|
|
|
|
|
Ok. I got how to add it.
We have to use a tool strip and then add buttons, labels etc accordingly.
However, If i need to change the image of the buttons, for example, if I want a button to display a file icon, I have to change it in the properties.
In that case, I have to choose the image.
Can some one tell me where all the icon files are stored.?

Hi!
i want to use threads in my C# asp.net web application. i m able to use static function in thread but when i use nonstatic function in my thread with the instance of class then it gives no error or exception but thread is not started and no functionlity in done in thread.
Can anybody help me 4 solving this problem. I need pure C# code not Html.
Thanx

Hmph... when user sends request to server it is serviced in new thread. When that request is finished all resources are released so probably same happens to thread you made and instance of class which method you call.
Surely there are better ways to solve any kind of problem you have... what are you trying to accomplish?

I want to see an example of threading in HTML 
Seriously, though, there shouldn't be a difference between static and instance methods except that thread safety is normally easier to manage in static methods. I've used both techniques any they work great.
Damn, i just realised that you are in ASP.Net. Are static variables shared between instances and instance variables per instance? The code below is for winforms but i guess it's not going to help much.
public partial class Form1 : Form<br />
{<br />
public Form1()<br />
{<br />
InitializeComponent();<br />
TestingMethod();<br />
}<br />
private void TestingMethod()<br />
{<br />
myObject obj = new myObject();<br />
Thread t = new Thread(new ThreadStart(obj.SlowMethod));<br />
t.Start();<br />
}<br />
}<br />
class myObject<br />
{<br />
public void SlowMethod()<br />
{<br />
Thread.Sleep(10000);<br />
Console.WriteLine("here");<br />
}<br />
}
This code seems to work fine for me.

I've looked up and down for this and came up short. I'm trying to change the scrollbar position of a site loaded into a WebBrowser (2.0) control.
Edit:
And by scrollbar position I mean being able to set the X/Y values. Something along the lines of: (pseudo code)
webBrowser.SetScrollPosition(500, 500);
That would scroll the document 500 pixels to the right as well as 500 pixels down.
