Thanks !

I have solved this by using a very complex and bad algorithm. That is why I have not posted it here. If anyone does want it please let me know.

Basically I am using a mod in Solr to return the hit words back to me and trying to map the words back to the original text. Unfortunately This is as much info I can cram into a comment. This is kind of like a sub - sequence problem.

we need only one element from a row. You method will yield ones with many elements from one row.

the problem is that i do not know how many elements there are lstInts. Therefore i cannot use nexted loops like you did.

Honestly this makes no sense. I do not think you understood my problem.

it just shows how to loop through all the elements. It doesnot tell how to get the unique combinations.

Thnaks man - I was thinking of using the same thing. In fact already did it.

hi, the problem is that all connection strings are with in the dataManager class. I cannot use them. All I can use in myProject is DataManager.GetNames(). The programs has to automatically use the appropriate dll depending on the location.

you can check out this link http://stackoverflow.com/questions/2265412/set-timeout-to-an-operation

I would after trying all approaches, i would HIGHLY recommend not using the task.wait() as it causes the application to become VERY unstable. The thread.abort method seems to be the best method. I ended up going for a !t.join(...) clause as it seemed the best way with fewest errors. Needed a few mods to the calling function to include the try catch blocks to catch the abort thread exception but seems to be worth it. Thanks Man

Thanks man, will get back to you after going through this.

Here was is a solution i thought of but I am having difficulty implementing it. I start 2 threads from my main loop. I make one thread sleep for 10 minutes and the other thread actually run my function. If the function returns a value before my sleeping thread then it is fine else abort the thread. But implementing it seems very hard.

Answers it the best !

This not what i want. I want the program to 'automatically detect' if a particular iteration is taking more than 10 minutes. For example ,
Stopwatch sw = new Stopwatch();
sw.Start();
for (int i = 0; i < 10000; i++)
{
if (sw.Elapsed.TotalMinutes >= 10)
{
// some actions before breaking out the loop
sw.Stop();
break;
}
MyFunction.Run(i);
}
if (sw.IsRunning)
{
sw.Stop();
}
If a loop in MyFunction.Run(i) takes more than 10 minutes this will not break/continue my loop. What I want to say is that the program must not wait for the loop to end but must take affirmative action as soon as 10 minutes is up. your code waits for it to end the current iteration and then checks for the condition in the next iteration. I think we need to use threads but i'm noob in that.

Thanks for the reply though.

can you tell me what characters come in this range ?? + to x ??

Are you sure that the tag property is string ??

The problem is that creating regexes for expressing the same thing in different ways(there are hundreds of ways documents can express information). It would be VERY hard to use regexes for this. There are no 'regular' patterns in the documents as they use free speech. That is why using regular expressions is so hard.

Hi Tadit, this was my very first go at the problem. However, I have more than 100k documents to process and making regular expressions to match even 1k documents is very very hard. I think I need to use something more complex. I wanted to know what are the various approaches to this problem and how people solved it and the references they used. Thanks

I wanted to know if Natural language processing could solve my problems. Regexes were just my first (not very good) effort at the problem. I wanted to know other solutions to this. Thanks.

Any idea how I can color individual words in a paragraph?? He only gives an example of coloring the whole paragraph.

The example project is not opening on my computer :(

Hi, both the links you provided are for richtextBoxes in WinForms. I am working in WPF. Thanks. BTW I am not really specific to RichTextBoxes. Any other control will work just fine for me as long as it is a WPF control.

How so ?

Thanks but i have a predefined set for this already.

Additionally, I am not using XAML as there is a very complex logic to which cells I want to highlight. This works fine if the datagrid fits into 'one page' of sorts, i.e, there is no need to scroll. But if i scroll down and lose sight of the cell, The background change which I made jumps around.

Can you atleast tell me why you think using a IValueConverter will help my problem ?

Please help me with the problem I have. Your link is almost completely irrelevant.

Furthur, I need two way binding because I can keep changing the cell I checked and the Textbox has to reflect the new value in the newly selected cell. Thanks for your help.

"The x:Name of the datagrid." what do u mean by that. Could you please help me with more specific syntax as I am still a bit confused ? What is Element Name and how is it different from path ??

Thanks, this works. No need to add to the cell to SelectedCells and it is read only as you said. Very helpful mate :)

Do i need to add the DataGridCellInfo for the specified cells into SelectedCells or will be automatically done if I set the IsSelected option to true ?

Thanks Pheonyx, I will try out the solution now. Will get back to you on this.

basically i know how to change the background colour of the cell. I can get the cell using this method (already using this), you can ignore the highlight flag stuff as it is specific to my app.

public void ColourCell(int row, int column, Color color, bool HighlightFlag = true)
{
DataGridRow rowContainer = GetRow(row);

if (rowContainer != null)
{
DataGridCellsPresenter presenter = GetVisualChild<datagridcellspresenter>(rowContainer);
// try to get the cell but it may possibly be virtualized but enable virtualizion is off
DataGridCell cell = (DataGridCell)presenter.ItemContainerGenerator.ContainerFromIndex(column);
// now try to bring into view and retreive the cell
if (HighlightFlag == false)
cell.Background = new SolidColorBrush(Colors.MediumPurple);
else
{
cell.Background = new SolidColorBrush(color);
}
}
}
public DataGridRow GetRow(int index)
{
DataGridRow row = (DataGridRow)DataGridControl.ItemContainerGenerator.ContainerFromIndex(index);
if (row == null)
{
row = (DataGridRow)DataGridControl.ItemContainerGenerator.ContainerFromIndex(index);
}
return row;
}


static T GetVisualChild<t>(Visual parent) where T : Visual
{
T child = default(T);
int numVisuals = VisualTreeHelper.GetChildrenCount(parent);
for (int i = 0; i < numVisuals; i++)
{
Visual v = (Visual)VisualTreeHelper.GetChild(parent, i);
child = v as T;
if (child == null)
{
child = GetVisualChild<t>(v);
}
if (child != null)
{
break;
}
}
return child;
}

Thanks Kenneth and SA for the edit, but i wanted to know the implementation in MVVM pattern and not in the event-driven programming model. I am sort of experienced in Winforms and already have the implementation in that(dataTable binding) but i am unable to wrap my head around the Commanding aspect of MVVM. Anyways My 4 for giving me the answer I deserve and not the answer I need :P

I wanted to say ObservableCollection(DataGridTextColumns) - the tags must have been deleted !!

I would have named the properties "column1", "column2" and so on so that I could dynamically generate the property names based on the row or column number.

I do have a Table Class as you say. I have simplifies the problem here a bit so that I could get a generic answer. I have found a nice example of adding properties dynamically here "http://www.shujaat.net/2012/09/dynamically-generated-properties-using.html" which I was planning to use but I could not find a way to bind the columns dynamically. Maybe a ObservableCollection ?
Thanks for taking the time to help me out - appreciated

Thanks Yair-I, i didnt know about the EnableModelessKeyboardInterop(). Thanks for all the links too.

If you tell us your errors we can help you.

And again another problem is that the number of rows and columns are not fixed. I have another assembly which sends me this data.

The data represented in the matrix is a real table(example http://corpeconresearch.files.wordpress.com/2009/08/corpecon-philipppine-stocks-guide-sample-3_page_4.jpg). Each node has a reference to its column header and row header. There is no advantage of having as equally sized grid. I want to be able to edit and modify the data in the table and add new rows / columns. Hope this clarifies why i want to use a Data Grid

Members of MyClass :
String MyText;
List (tuple(int,int,int)) reference;
//Each node references other nodes. On selection of a node the other referenced nodes must be highlighted. the tuple is of the format "row, column, referencetype"
