Hi,
please publish actual code, not something that resembles your code but would by no means compile.
Why are you using a Thread AND a BackgroundWorker (3 each), just have the job done by the BGW,
it can both execute the job and report progress.

Technobizz,
Like Luc said, show some actual code. Also, how do you update the progress changed?, do you just pass it the current position in the iteration (i am guessing you're using a loop somewhere) or the actual percentage complete?, there is a difference.
Regards,
Gareth.

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
try
{
int row = 0;
int col = 0;
row = e.RowIndex;
col = e.ColumnIndex;
object val1 = dataGridView1[col, row].Value.ToString();
MessageBox.Show(val1.ToString());
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
error: object reference not set to an instance of an object
i'm getting this error. Please tell me how to correct this.
I've created a cellcontentclick event to get the row and column index where the checkbox is checked now i want to get the particular column value at this rowindex. As i want to get the address column data corresponding to the row in which checkbox is checked.
Thanks in Advance
Cheers

Hello,
I'm writing application with very complex configuration (System.Configuration). I need to pass ConfigurationSection or ConfigurationElement inherited class object as a method argument, but method executes in separate AppDomain, since neither ConfigurationSection nor ConfigurationElement doesn't inherit from MarshalByRefObject classs I constantly get a SerializationException exception.
If I add SerializableAttribute to my configuration section it works, but I can't modify any variable.
What can I do ?
Thanks in advance.

Use the System.Diagnostics namespace. It includes the Process object that lets you run external programs.
using System.Diagnostics;
...
...
Process p = new Process("notepad.exe");
p.Start();
It also includes methods such as WaitForExit() that tells your program to wait till the process it terminated, and also the 'StartInfo' that lets you set customized settings for running a program. Browse the namespace for more details.

You can use SelectionStart, SelectionLength and SelectionFont properties of RichTextBox class for that.

Hi, I have a grid (4 rows x 5 columns). I need to sort grid by last column. But I want to trace what changes were made to row order. I need this info to:
1. Change row header's text 'cause it doesn't change automatically during sort.
2. Change the columns order, i.e. I have rows 1,2,3,4. After sorting I have 2,3,1,4. And I want my columns moved in that way: 2,3,1,4 (with DisplayedIndex property for example)

Hi,
Would anyone tell me how I can store HTML within XML ? Because, when I have < tag in XML, the XML gets screwed up. Also when attribute values have " character, XML gets error.
|
|
|
|

You just have to encode the text properly. Example:
<root>
<html>Some text with <abbr title="HyperText Markup Language">HTML</abbr> code in it.</html>
</root>
Despite everything, the person most likely to be fooling you next is yourself.

Thanks for the reply. I understood. but what about the situation when I had special characters like < in my html so when < is encoded to < and stored in xml, it will be mixed up with the < chars and when it is decoded, both encoded < and original < will be decoded to < character, right ? So, what is the effcient solution about this scenario ?
Thank you in advance.

When you encode html code with an entity like < in it, the & character is encoded as &, so the entity becomes &lt;.

Hi all.
I have a XML file. something like this :
<FoxMark ELEMENTS="442">
<BOOKMARK1 ID="1" />
<BOOKMARK2 ID="2" />
<NODE4 ID="4" NAME="FireFox" DESC="" />
<BOOKMARK5 ID="5" />
<BOOKMARK6 ID="6" />
<BOOKMARK7 ID="7" />
<BOOKMARK8 ID="8" />
<BOOKMARK9 ID="9" />
<BOOKMARK10 ID="10" />
<BOOKMARK11 ID="11" />

I want to read this file, line by line and LINQ.
Can you help me?

You can use the File.ReadAllLines method to get the file into a string array, but I suppose that's not really what you want to do.
When you say that you want to read the file line by line, what do you mean really, and how does LINQ come into the picture?

Thank you Guffa .

OK, in my XML file there is a node in each line.
Now I want to read XML file node by node thus I thought that I must read XML file line by line.
Do you understand what I mean ?

An XML file is not line based, so reading it line by line doesn't make sense. An XML file is just as valid if it looks like this:
<root>
<node>1</node>
<node>2</node>
</root>
or like this:
<root><node>1</node><node>2</node></root>
Use an XmlDocument object to read the file.
The DocumentElement property gives you the root node, from there you can navigate the tree structure using the FirstChild or ChildNodes properties. When you reach the node containing the nodes that you want, the ChildNodes property gives you a collection of all the nodes.
Another alternative to get the nodes from the XmlDocument is to use an xpath expression with the SelectNodes method.
