I am having trouble detecting if "down" or "up" key is pressed within a textbox.
Evidently those keys do not fire the "KeyPressed " event.
Does anyone know how to detect when they are pressed?

Try the KeyDown event instead, it will get arrow key presses :)

Check the args against the Keys.Down or Keys.Up
Thanks, it worked great. But now I encountered another problem.
It seems that the Up and Down Key moves the selectIndex.
I adjusted it by simply adding or subtracting by 1. It doesn't work when the selection index is at the beginning and the end of the string since it seems to be increment/decrement after the event fired.
It won't let me increment pass the length of the string so if I press Up at the end of the string, it will always move the selectionIndex back 1.
Is there a way to disable moving the caret on up and down? or I have to use a round-bout method??

You should be able to intercept the message before it makes the move to begin with.
In your KeyDown handle method, it will have received a KeyPressArgs or something similar being assigned to variable e
You can then set e.Handled = true
So the OS doesn't pass the event any further, since you have handled it.
Thank you very much for the help :)
Sorry about being a total newbie at programming.
Much appreciated :)

Hi,
I have a windows form with a combobox on it (it has the DropDown as

Hello,
I have a program that intensively allocates and deletes lots
of relatively small objects, using "new" operator. The objects
themselves are composed of smaller objects, again allocated using "new".
From my tests I deduce that a considerable part of the computational
time is spent on the memory allocation, which makes the program
substantially slower compared to the equivalent code written using

What I do mind, though, is the browser doing its damndest to smash the thing

just "let go", and set the table free, scrollbar be damned.
Is there a way to tell the browser that my...

But there's a disturbing lack of *built-in* docs for Ruby.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
