how should i MOVE THE IMAGE BOXES IN A VERY SMOOTH MANNER?

i have figured out hwo to move the images with easy and normal vbkeycodes...BUT CAN NEONE TELL ME HOW SHOULD I MOVE IT SMOOTHER!! coz u know to move i i always have to press the ke again n again!!....I WOULD RATHER REFER JUS PRESSING ONCE AND HOLDING ON TO THT...Rather than pressing the arrow keys again n again!!

it looks somewha like this

if keycode = vbKeyup then
img1.top = img1.top + 32

and u know so on?!?!??!

Well there are certain events KeyUP KeyPress and the one you are looking for is KeyDown event for when the user is holding down the key.

I would also suggest using PictureBox's maybe as Image Control's tend to flicker when being moved around a form.

Most games typically use a game loop, and poll the keyboard state each frame, then update accordingly. I wrote a Game Loop tutorial in the Tutors Corner forum (or on my website http://members.shaw.ca/optikal ) if you don't know what a game loop is.

You could also have use a Boolean like:

Private blnMove as Boolean

then in the Keydown event (with a test for the key you want pressed) make blnMove=True. Then in a Do While blnMove = True loop (either in Form_Activate or a timer), put the img1.top = img1.top + 32 code. This is one (simple) type of game loop that Optikal was mentioning...

You can either stop by moving putting an "If X = somevalue" inside the Do Whole loop or have a KeyDown event for another key make blnMove=False.
