Can you tell me how can i make all textboxes and richtextboxes take CTRL+C command takeble and right mouse click edit menu enabled by default ?

What kind of textboxes is it that don't take those command?
Passwords textboxes of course does not support copying.

Hello,
Thanks for replying me.
In my windows form, I am using 5/6 regular textbox and richtextbox.(not password) I did not write code for those boxes to take CTRL + C command (like KeyDown event handler). Some boxes are by default listening and some of them are not listening those command. I had to write code for those boxes to listen CTRL+C command.
Thanks

The commands are built into windows, so most standard controls respond to them.
Can you see any difference between the textboxes that do respond to the commands, and those that don't?

Hello ...
If i have transactions for the 3 subsequent commands to execute, is database locked for this time to prevent interruption by other threads (automatically) ? Or must I use lock statement for this purpose ?

Hi Colin'
Thanks for your reply.
Actually my question was like this,
Situation,
{
command A
commandA.transaction = transactionA
commandB
commandB.transaction = transactionA
commandC
commandC.transaction = transactionA
// execute all commands
transactionA.commit
}
Now , do I need to lock the mentioned block as I am already using Transaction. You replied me saying that, database will not be locked, I should use transaction. I am confused. Did you mean if I use transaction then SQL will be locked ? if so, then thats what was my question

You do not need to use the C# keywork lock in this situation.
emran834 wrote: You replied me saying that, database will not be locked, I should use transaction.
If you use the lock keyword, all you are doing is locking other threads from the same application out. However, other applications can still access and modify the database.
emran834 wrote: Did you mean if I use transaction then SQL will be locked ?
If you use the transaction SQL Server will ensure that no other process can modify the same part of the database that you are modifying.

I have a code structured like this:
Class A {<br />
...
private void methodA () {<br />
B b = new B();<br />
...
}<br />
<br />
}<br />
<br />
Class B {<br />
...
~B() {...}<br />
}
will the destructor run in class B when the methodA in class A finishes? If not, how can i make it run?

When the garbage collector finds an object with a destructor, it places it on a special queue, hence the destruction of an object is not deterministic (you cannot predict when it happens).

No, it wont. The destructor will be called when the garbage collector is about to remove the object.
If you want some clean up in the object, let the class inherit the IDisposable interface. When you are done with the object, call the Dispose method to do the clean up.
A good way of disposing of objects is using the using keyword. That will create a try...finally block with the Dispose call in the finally part. That ensures that the Dispose method is always called, whatever happens.
Class A {
...
private void methodA () {
using (B b = new B()) {
...
}
}
}
Class B : IDisposable {
...
~B() {
this.Dispose();
}
public void Dispose() {
...
}
}

b { font-weight: normal; }

I have this:
internal enum WelcomeData { Language, NumCusAdult, NumCusUnder4, NumCusUnder9, NumCusSenior, TimerEnable };
Everytime I use the enum as index in an array I have to cast it as int:
Data[(int)WelcomeData.Language] = Language;
This is very annoying
how do i make the enum act as int?
thx thx

Emm, subclass the array and define an indexer that take in the enum type?
