Game Programming :: Detecting Whether One Of The Arrow Keys Is Pressed, All The Other Keys Seem To Be Detected Apart From The Arrow Keys?
Oct 21, 2008
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.
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.
i am trying to develop a program which will:to beging with, allow a user to use the left and right arrow keys to control the panning of a particular sound on loop. the actual panning dosent have to be programmed i could just instruct the program to play out the corresponding pre recorded panned sound?once achieved i hope to then develop the program to test a users ability to pan one sound to match a stationary sound at a given angle. i will need to record the time taken to achieve this, the number of key presses made and how accurate their answer was.i am using visual studio 2005 to build my program?
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?
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.

I use the up arrow means , it must goto the previous text box and if i use the down arrow means , it must goto the next text boxes. Totally i m used 15 textboxes. From text box1 onwards, if i use the down arrow means goto the next textboxes and also repeated to all text boxes.(1 to 15) From text box15 onwards, if i use the up arrow means goto the previous textboxes and also repeated to all text boxes.

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. [code] As I said, all key events will fire the KeyDown with exception of the arrow keys.I have tried the Keypress event also and had the same problem
How will I navigate the buttons using the arrows keys? Example, from button Broccoli, I want to go to button Portobello Mushroom, i will just press arrow down. But it is not working. For me to reach button Portobello Mushroom, I have press the arrow right 6 times. How can I use the arrow down?
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]
I wrote a program for a stopclock with button control. The button control is to start and stop the clock. How can I use the arrow keys, instead of the mouse click on the button, to start stop the stopclock.
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 MessageBox.Show("DateChanged")[code]....
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.
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.)
I've already tryed using the case key event handler, but I must be using it the wrong way, because VB 2008 express (what I'm using) produces a bunch of errors("Type expected" as well as it won't work). This is what I've tryed:
Private Sub GameField_KeyDown(ByVal Sender As Object, ByVal E As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyDown Select Case E.KeyCode
Basically I need to handle a keypress or keydown/keyup event on a form, specifically for the Up, Down, Left, Right arrows. Using the below, nothing moves. However, if I change (Keys.Left) to (Keys.A) then a capital A will move the object. vbnet
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Left) Then 'Note that 'man' is a PictureBox. man.Location = New Point(man.Location.X - 5, man.Location.Y) End If End Sub
If a tab is highlighted and you hit the left/right arrow key, it goes to the previous/next tab. I want to remove this functionality. I only want the user to be able to change tabs with the mouse click.
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..
I want to make a Pac-man game, or something close to it, but I don't know how to make the image of Pacman rotate and move when different arrow keys are pressed. How would I go about making a code that moves an image when an arrow key is pressed?
Is there any way you can move a panel using the arrow keys during runtime?and is tehre a way of popping random objects in a game. Like you have this spaceship moving and your "Alien foes" or whatever attacks you. So you want them to pop up randomnly every few seconds or so. How?
I am trying to move a Rectangle Shape using the arrow keys and i have done multiple codes and none of them work. Can anyone help me with the coding.[code]also I am not sure if the code goes in Form1_KeyDown or RectangleShape1_KeyDown
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?
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.
I have a group of radio buttons inside a groupbox and I don't want the user to be able to move the focus away from a button by using the arrow keys. I've tried the following keydown event, but it never gets fired:
Private Sub rbCode_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles rbCode.KeyDown ' If an arrow key is pressed, maintain focus on this radio button If e.KeyCode = Keys.Left Or e.KeyCode = Keys.Right Or e.KeyCode = Keys.Up Or e.KeyCode = Keys.Down Then
I want to have a stick figure kind of person who moves around with the arrow keys, and i want to have him move in different positions depending on what key is pressed. What is the best way to acomplish this without using pictureboxes?
so I've begun developing another little rpg like game w/ visual studio 2010. I'm trying to have the arrow keys control a little square in the form but I've searched all over the internet and haven't found too much useful info. So first thing's first, how can i make a key perform an action, and then, if you know how, what code do i use to make it move the square on the form.
