You mean a question? 
1.
Console.Write(new String('x',100).Replace("x","Satish\r\n"));
2.
Console.Write("ssssssssss".Replace("s","ssssssssss").Replace("s","Satish\r\n"));
3.
public string msg(int cnt) { return "Satish\r\n" + (cnt > 1 ? msg(cnt - 1) : string.Empty); }
Console.Write(msg(100));
Despite everything, the person most likely to be fooling you next is yourself.

Hi friend i m stuck in one problem.
my question is like..
I have added treeview control in my form and also i hav added treenode to this treeview.
that is basically name of all table in my database..
This part i hav done.
Now i want to create a gridview which include all column name of given table name.
Now i want to perform drag and drop operation across treeview.(treenode provide that table name) --(so i want to drag treenode to another panel of my form where i will create gridview dynamically or i can say that from this drag and drop i m able to figure out which table gridview would be created.....)
i have tried all event of treeview but still not able to do this task......?
Hope you understand my problem.
Thanks lot.

You say you have tried all the events on the tree view but no luck?! What have you actually tried?
This all depends on how your application is designed. I'm not really sure from your post exactly what you have tried but here is the overall steps.
1. Set AllowDrop = true for both the treeview and gridview
2. Connect to the treeview drag drop events i.e. so the user can drag an item from the treeview. (plenty of examples on this site)
3. Connect to the grids drag drop events i.e. so the user can drop items into the grid. (plenty of examples on this site)
4. On the grids DragDrop event get the item being dropped i.e. the tree view item.
5. Depending on how your application is designed, populate your grid using the data stored within the dropping node object OR get the data you need from a data set\data source and populate the grid that way. This step all depends on your design.
I cant see any real problems with implementing what you are asking, thats if i have understood what you have asked correctly.

Hello, I am not certain that it should be behaving this way but I will explain and hopefully someboday will have some insight/help which would be great.
I will throw together a rough example below, We have a transaction contain multiple saves:
Try
{
Save1.Update(dt.Select(null, null, DataViewRowState.Added));
Save2.Update(dt.Select(null, null, DataViewRowState.Added));
Save3.Update(dt.Select(null, null, DataViewRowState.Added));
}
Catch
{
Trans.Rollback();
}
We have logic in the sprocs to ensure that no invalid data is saved, if Save1 completes the RowState is changed from added to unchanged. However if Save2 then throws an exception the try..catch rolls the transaction back however the Row in Save1 remains with a RowState of unchanged and so that row will not be persisted to the database once the invalid data is corrected and save is called again.
I would have expected the RowState to return to Added if the transaction is rolled back. Has anybody experienced this before? Is this what you would expect?
Thank you for any help or insight, it will be greatly appreciated.

using System.Threading;
Thread myThread = new Thread(new ThreadStart(_listener.Prepare));
myThread.Start(); The Start call on myThread is quite important. Without it, the thread doesn't start, and no amount of debug code in the 'Prepare' method will get called and you look a complete arse when you ask a colleague for help. If you call Start on your thread, your thread starts and everything is really good.
It's gonna be one of those weeks.

I want to load an assembly from a file, change a method body and save it to a file using reflection. I do not want lot of for loops to traverse through the entire assembly and do all things manually. I just want to change one method in one module in the assembly.
Thanks.

Sounds nasty.
I think you're going to need a recursive method to do this. Reflection wasn't designed to help you hijack someone else's dll and inject your code into it. That's a scary thought.

Thanks for your reply. I can do it really with some iteration or recursion easily- when I know that there is no other way.
I am trying to implement AOP like feature without defining a new class. Some classes do use reflection and my AOP proxy is bypassed in that case. If I could inject some IL at the method beginning it'd be nice. I do not have access to the source but can define which dll is going to be used with the application.
I know its nasty. I really prefer to walk with my girlfriend to write code- but still some people does not like my idea of walking. Joking
Thanks.

Have a search on this site for the LinFu articles by Philip Laureano. They sound like just the ticket for you.

Hello Everybody

Hello,
You may use the Clipboard to copy the data/text and then paste it to your destination.
For example the code below will copy the text in the textbox to the clipboard and then you may paste it to your destination:
//Copy
Clipboard.SetText(this.textBox1.Text);
//Paste
this.textBox2.Text = Clipboard.GetText();

Dave

problem
thanx in advance

Are you getting any error ? Make sure all instances which has a Dispose() method is called once you finish using it. Put the class instances which are disposable in a using statement. This ensures the disposal of objects.
