I want to realize the following:
During one loop, a status form window is displayed, it is closed when the loop is done. but I want to stop the loop before the loop finishes. I have one button on the status form to be clicked to stop. but no response when I click it. How to do it?
thanks!

Hello,
You have to call "Application.DoEvents()" inside the loop.
All the best,

Hi, Martin,
thanks a lot. It does work.
However, I met another problem.
when I click the button to stop the loop, the firt click does not work, that means I have to click two times, after that, then it work perfect.
further I found that I have to click the form window first then I can handle this window, or else I can not. I tried to use Activate() and Focus(), neither works, Could you please give me one hint for that?
thanks a lot.

well, you must have some condition inside your loop, you have to "and" that condition with a boolean flag which is set when the cancel button is clicked.
eg
bool cancel = false;<br />
<br />
while(yourCondition && !cancel)<br />
{<br />
}
Then your cancel button would just set that cancel variable to true. You will need to do your loop within another thread in order to keep the form responsive.

I am using SqlCommandBuilder to update data in DataSet to DB and I got a problem is:
DataSet includes 2 tables : 1 is Master and the other is Detail
1. When user adds new row in DataTable => This record must be insert into Master table first, and then it will be inserted
into Detail Table.
2. When user delete data in DataTable => This record must be deleted in Detail Table first, and then it will be deleted
in Master Table.
User can add new, edit or delete data in DataTables until they click Save button => Update data in DB.
Please help me how can I do this with SqlCommandBuilder.
Thanks a lot.

2 things:
1. Pay attention to rule 7 on forum usage.
2. You only posted your original question 90 mins ago. Please be more patient!

I think I understand your problem. This is in the C# forum, the link takes us to the ASP.NET forum. You've found the 'cross post' bug. To prevent this bug from happening, stick with your original posts, in the original forums and give the people answering your questions a little more help/information than you are doing.
People will spend less time on your numerous posts if you start to cross post / duplicate posts / just post links to other posts you've already made.

Hey, the 'new' keyword is to explicitly hide the base class members
But, if you want to use it, you have to call the method from the derived class. In this case you surely need to create a reference of the derived class other than a original base class reference.
Since you have already created the Program object to a user reference, all you need to do is to perform a cast:
(Program)u.print();

It's working just fine. You have a reference to user, so when you use the print method, the method in the user class is used.
If you want the method in the Program class to be used when you have a Program instance references by a reference to user, you have to use a virtual method instead of using the new modifier.

Hi,
I guess you will have to use follwing in your application.
[DllImport("User32.dll", ExactSpelling=true)]
private static extern bool MessageBeep(uint type);
play what ever sound you want to play.
