I have a problem detecting whether one of the arrow keys is pressed, all the other keys seem to be detected apart from the arrow keys??? I have set key preview to True........ It detects the arrrow keys BUT ONLY if I have NO other controls on the form??? example..
Me.Text = e.keycode
It works, but then if I add a button for example, it stops.
just wondering how i could give my auto typer hot keys, for example they press f1 to start the typer f2 to stop it.

How could I loop through a list of the keys that are available in the 'Keys' enumeration? It seems like it should be something easy to do, but I'm not having any luck finding a collection that I can loop through.
View 6 RepliesSo I found this little morpg. The game is fun but really repetitive. I would like to simplify some of the tasks in the game. I do not know how to start this project. How can I recored arrow keys and then tell the computer to enter the arrow keys? One of the objectives in the game is to run around a farm 2x and scare away any wolfs. So the commands would be "arrow key up" for 30sec and then "arrow key right" for 4 sec and repeat. I have worked with robots in real life for some time. We would fill arrays with such instructions. One of the most fun things to program! But I have no idea how to do this in VB.
View 12 RepliesI need to capture the left and right arrow keys in Form1.KeyDown event so I can use them as hot keys. Instead they seem to be assigned to tab order (move focus to previous/next control) and the KeyDown event never gets called. How can I remove the arrow keys from tab order and use them for my hot keys instead?
View 2 RepliesI tried a couple of the send keys and they will not send any keys at all. I need a true Space bar input (SendKeys does not work for me). Also, I would like this to work on 32 and 64 bit computers. Let me know if you know of any good examples. I would love to have the ability to send a string in the future, but I can add that feature myself. [code]

View 4 RepliesI want to change the "a" and "d" to key controls left and right perspectively. and I am having some trouble wiht the key up event. KeyChar works for KeyDown (after I forced it to) but not for KeyUp (even though they share the same things). I finally figured out how to get the picturebox to change its picture, but now I am stuck at this part. getting an animation in, and when im done moving, get the animation back to the idle picture. im also having a little bit of trouble with movement. pictre - as a split second of movement and (space) as a split second of not moving, when i begin moving, lets say it goes this way (there is a space right after the first -, so that was a split second that it stopped and then started continuously started moving again). how can i make it so it goes nice and fluid once you start moving? also, if i were to press any single key while holding A or D down, it either stops and i have to press the key again to move it move or, it goes in the other direction(if I hit a then d, or d then a). and in the key up event, id like it so when the a (or d) key is up, it goes back to the stand animation, and when moving, it goes to the moving animation.

I have an image viewer application which consists of a Panel with a picture box on it. I want to use the arrow keys to iterate through the images in a folder. I have programed other keyboard shortcuts and all of them work except for the arrow keys, my program does not even acknowledge the KeyDown or KeyPress Event with the arrow keys.
