Recored Arrow Keys And Then Tell Computer To Enter Arrow Keys?

May 23, 2010

So 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.

Arrow Keys As Hot Keys?

Feb 28, 2010

I 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?

Key Up And What Are Arrow Keys

Dec 18, 2010

I 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. [code]

Arrow Keys In MDI Focus Is Lost

Nov 28, 2009

I had previously made a simple Pong program which use keyboard to control. The control includes "s" to start the game, "p" to pause, "r" to resume and left, right to move the paddle specifically. This program work with little problem. The first problem I encounter is if I insert even one single button on the form to display instruction, the arrow keys will no longer work. But I get around it by using Menu Strip instead.

Then, I am required to put this program, among others into a MDI program. And this is where the problem happen. If I have this Pong game loaded, and I press "s", "p", or "r" keys, it have no problem, but if I press the "left" or "right" keys, it will not move. I am speculating that maybe the focus is lost when arrow keys is pressed or something similar, but I have absolutely no idea what is happening. I have tried giving focus back to the form if focus is lost, but to no avails. And this is the code for the movement of the paddle. This reside on a form, the movement itself is passed to another class. The MDI parent is on another form. [Code]

Disallow Arrow Keys In MonthCalendar?

Mar 8, 2009

I want to update some things on the form when the user clicks a new date (or changes the month, which automatically selects a new date). If I use the DateSelected event, it seems to work as expected when I use the mouse. However if the arrow keys are used, the event does not get triggered. If I use the DateChanged event, it seems to go into an infinite loop. The message box pops up a zillion times when I click the arrow to change the month:

Private Sub MonthCalendar1_DateChanged(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DateRangeEventArgs) Handles MonthCalendar1.DateChanged

The only problem with using the DateSelected event is that if the user uses the arrow keys, the event is not fired. I thought I could fix this by disallowing the use of the arrow keys, but I couldn't find anywhere to do that.

Textbox Navigation With Arrow Keys

Dec 28, 2009

I have a group of textboxes for a tab editor. 6 vertcle, 25 horizonal. ( numeric guitar sheet music) I want to be able to navigate them with the arrow keys. If I number them in chronological order from the bottm left, the up arrow key would be "+1", down arrow key "-1", the left key "-6", & the right arrow key "+6". That way I can navigate any possible way on the array. My question is, "How do I do this in code?". ( I have never had a school coarse of any kind in programming-learning VB Express at home.)

KeyDown Event Not Firing For Arrow Keys?

Aug 8, 2010

I have a weird problem. Ive created a UserControl that can be used to pan and zoom an image but when ever I add the control to a form my arrow keys will not trigger the KeyDown event anymore. If I remove it no problem.

If I try and listen to the KeyDown event on the control itself nothing fires either!

Ive set the KeyPreview property on the for to True.

I'd be happy to supply the code if anyone think they could solve it..

Use A Vertical And Horizontal Scrollbar And Have The Arrow Keys?

Jan 14, 2010

I'm having a problem assigning the arrow keys to the right scrolling events.I have a VScrollbar and an HScrollbar. I want the left / right arrow keys to scroll the horizontal bar, and the up / down arrow keys to scroll the vertical bar. The default behaviour seems to be that the first created of the two (VScrollBar or HScrollbar, depending on order of creation) received all arrow key events as a Scroll event. So when I push up / down / left / right, it is my VScrollbar that moves (HScrollbar might move also with the left / right arrow keys, I don't remember). I tried catching the KeyDown event on my form, to manage the left / right / up / down keys myself, but apparently the Scroll events are triggered first...In any case, what would be the "right" way to use a vertical and horizontal scrollbar and have the arrow keys do what they're supposed to do in VB. NET?

Forms :: Moving An Image In A Picture Box With Arrow Keys?

Oct 28, 2010

I'm currently working on a project for university, basically we were given an incomplete program to finish off with bonus points for adding addition features in.Part of the program is to move an image (a monkey) around the picture box (pen). Now to move the monkey we use 4 buttons on the form called Up, Down, Left and Right, however as we need to move the monkey around to test other parts of the program it gets annoying having to click on the button. As such I was able to get some code which allows me to move the monkey around using the arrow keys (I think you can all see the benefit of this). When I use the code in a blank form it works fine, however when I add a button onto the form the arrow keys will instead highlight the buttons.basically set up a button to disable all buttons on the form until a certain key is pressed, however I would prefer not to have to do this.
