Cant figure out how to use keys, any ideas?

Hi Guy's,

I'm pretty much a newbie to vb, what I'm trying to do is control an rc car from my pc and I'm trying to do this through an interface board I have. I have code below where I have started the design but I'm trying to figure out how to take inputs from the arrow keys which I cant figure out, I've just tried to set up a test by changing the colour of labels but it's not working, can anyone see my error? Please excuse any foolish newbie mistakes.

Thanks,
Oisin

Thread moved from the 'Application Deployment' forum (which is for questions about installing/distributing your software) to the 'VB.Net' (VB2002 and later) forum

For the benefit of others, ozirock's profile says VB 2005 Express

You didn't add handlers to your Form_KeyDown and Form_KeyUp method.

What I would do is something like this:

vb Code:

Private Sub MainForm_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
 
        Select Case e.KeyCode
            Case Keys.Up : MsgBox("UP")
            Case Keys.Right : MsgBox("RIGHT")
            Case Keys.Down : MsgBox("DOWN")
            Case Keys.Left : MsgBox("LEFT")
        End Select
 
    End Sub

ps: Don't forget to set the KeyPreview property of your form to True!

Sorry about the mix up with the forums guys.

Thanks for your help gonzalioz, I can get your code to work in a file on its own but when I try to integrate it to my original code, it has no effect, I'm wondering if the code I wrote to connect to the interface board is causing problems for my other code even though it's telling me there are no errors, could that be the case?

Or is the fact that I placed buttons on my form a factor? Is there a setting I missed related to this?

Also I didnt know about the KeyPreview property so thanks for that :)

Thanks,
Oisin

Do you mean the button1_Click method? I don't think so


What do you mean with integrated? English is not a my native language :). Did you change anything to my code when using it in your own app? If so, can you post that code?

The only setting that you have to change is me.keypreview = true (or using design mode) or else it won't work.

Sorry I just meant I changed my code to try change the colour of the label like I had been trying to do originally but I have since deleted my attempts and replaced my button pressing code with yours which I had tried on my computer and worked so I taught it should work in my original code but even the code below does not work for me.

I dont see what could be causing the problem because the only thing there now is to connect to the board, it's very annoying.

Thanks for your help,
Oisin

Remove your old key-event handlers if you still have them. If you have a duplicate procedure with different parameters you won't get an error, but only one of them will be called. If you have focus on control other than your form, handling MyBase.KeyDown() won't help you, but you'll have to handle that controls events instead. I recommend overriding the keydown event if you need to focus on other controls, like this:

Code:

---

Protected Overrides Sub OnKeyDown(ByVal e As System.Windows.Forms.KeyEventArgs)
        MsgBox(e.KeyCode)
        MyBase.OnKeyDown(e)
    End Sub

---

I placed that into my form like below but it didn't work but it works in a new form on its own no problem.


vb code:

Public Class Form1

Private Declare Function OpenDevice Lib "k8055d.dll" (ByVal CardAddress As Integer) As Integer
Private Declare Sub SetDigitalChannel Lib "k8055d.dll" (ByVal Channel As Integer)
Private Declare Sub ClearDigitalChannel Lib "k8055d.dll" (ByVal Channel As Integer)
' Public up, down, lleft, rright As Boolean 'to keep track of which buttons are already pressed


Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim CardAddress As Integer
Dim h As Integer
CardAddress = 3

h = OpenDevice(3)
Label1.Text = "Card " + Str(h) + " connected"

End Sub


Protected Overrides Sub OnKeyDown(ByVal e As System.Windows.Forms.KeyEventArgs)
MsgBox(e.KeyCode)
MyBase.OnKeyDown(e)
End Sub

End Class

End Sub

Umm.. that should work just fine. Is that the new forms code? If so, please post the old ones.

Or keyPreview right? I know it's not the same but it does the job in this case.

Something I just thought of:

When you make a connection. Are you sure it does connect and doesn't try forever? Maybe there is a loop somewhere that goes on forever, so your app never gets to running MsgBox(e.KeyCode) and MyBase.OnKeyDown(e)?

It's a little far fetched but you never know.


---
Sry for double post.

No that was the code in side my old form, which doesn't work for me, I have buttons on my form does that cause a problem?

Also I notice this byval e piece of code is in both the button and the keypress code, could one be stopping the other? What does the e mean, I am guessing is like a variable?

Thanks,
Oisin

Oh wait a minute, if I don't push the connect button it wont read the rest of the code?

I don't have the board with me, but it does connect cause I've controlled stuff by clicking buttons before but I didn't get the keys working.

No sry for the confusion. I meant:

If you click the button.. It will connect. But maybe this connecting business goes on forever. so when you press a key after you clicked the button it will never run.

But if you just run your app and press a button on your keyboard and nothing happens... then the problem is probaly something else.


This is really a mystery lol XD.

The code I gave you will pop up a messagebox with they keycode of whatever key you press on your keyboard.

Copied your code into a new project on my pc and it doesn't work either lol.

That really doesn't pop up anything when you press a button on your keyboard? Are you using VS2008?

O, now it works. Used this code of yours:

vb Code:

Public Class Form1
 
Private Declare Function OpenDevice Lib "k8055d.dll" (ByVal CardAddress As Integer) As Integer
Private Declare Sub SetDigitalChannel Lib "k8055d.dll" (ByVal Channel As Integer)
Private Declare Sub ClearDigitalChannel Lib "k8055d.dll" (ByVal Channel As Integer)
' Public up, down, lleft, rright As Boolean 'to keep track of which buttons are already pressed
 
 
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
 
Dim CardAddress As Integer
Dim h As Integer
CardAddress = 3
 
h = OpenDevice(3)
Label1.Text = "Card " + Str(h) + " connected"
 
End Sub
 
 
Protected Overrides Sub OnKeyDown(ByVal e As System.Windows.Forms.KeyEventArgs)
MsgBox(e.KeyCode)
MyBase.OnKeyDown(e)
End Sub
 
End Class

I am sorry, i have absolutely no clue why it doesn't work on your pc. There must be some setting/property that messes everything up.

This code works on its own in a different form but when I add it into mine its not working, I really cant understand it

If you add a few buttons to your form gonzalioz, does it still work?

Yes. Is keypreview set to true (guess it is, posted it a lot sorry :P). Even with dark anima's way using override etc.. you still need keypreview apparently.

Just to check I done it right, I click on the form, went to the properties section in the bottom right of my screen and changed the key preview property to true. That is what you mean right?

Yeah :(.

I think I got it though. If you have a lot of buttons on your form. The up down left right keys makes you select another button on your form! Did you try to press the key T for example when using the code dark anima posted? That works with me. The up and down etc keys however don't work, because all they do is go to another button.

No idea how to solve this though. You could use W A S D instead :)?

Ha thats it, you figure it out, well done, I'll just have to use letters instead of arrows I guess or just get rid of the buttons :)

Just tried some other events, and the keyUP event does work.. But also still does select a new button :). This also works and also still selects a new button:

vb Code:

Protected Overrides Function ProcessDialogKey(ByVal keyData As System.Windows.Forms.Keys) As Boolean
 
        Select Case keyData
            Case Keys.Up : MsgBox("UP")
            Case Keys.Right : MsgBox("RIGHT")
            Case Keys.Down : MsgBox("DOWN")
            Case Keys.Left : MsgBox("LEFT")
        End Select
 
        Return (MyBase.ProcessDialogKey(keyData))
    End Function

But I guess it can be quite frustrating when your controlling your rc car, when pressing a key the selection of your buttons changes constantly :P

That is perfect, it's exactly what I was trying to do, thank you so much for all your help, your a legend. You've no idea how excited I am to head home and wire it up now :)

I've one more question if you can help, any idea how to make it change back when the key is released I taught I could do below but i think it needs to be refreshed constantly or something like that.

I made two attempts and failed :(

vb code attempt 1:

Public Class Form1

Private Declare Function OpenDevice Lib "k8055d.dll" (ByVal CardAddress As Integer) As Integer
Private Declare Sub SetDigitalChannel Lib "k8055d.dll" (ByVal Channel As Integer)
Private Declare Sub ClearDigitalChannel Lib "k8055d.dll" (ByVal Channel As Integer)
Public up, down, lleft, rright As Boolean 'to keep track of which buttons are already pressed


Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim CardAddress As Integer
Dim h As Integer
CardAddress = 3

h = OpenDevice(3)
Label1.Text = "Card " + Str(h) + " connected"

End Sub

Protected Overrides Function ProcessDialogKey(ByVal keyData As System.Windows.Forms.Keys) As Boolean

Select Case keyData
Case Keys.Up : Label1.ForeColor = Color.Red
Case Keys.Right : Label4.ForeColor = Color.Red
Case Keys.Down : Label2.ForeColor = Color.Red
Case Keys.Left : Label3.ForeColor = Color.Red
Case Else
Label1.ForeColor = Color.Black
Label2.ForeColor = Color.Black
Label3.ForeColor = Color.Black
Label4.ForeColor = Color.Black

End Select

Return (MyBase.ProcessDialogKey(keyData))
End Function

End Class

Attempt 2 vb code:

Public Class Form1

Private Declare Function OpenDevice Lib "k8055d.dll" (ByVal CardAddress As Integer) As Integer
Private Declare Sub SetDigitalChannel Lib "k8055d.dll" (ByVal Channel As Integer)
Private Declare Sub ClearDigitalChannel Lib "k8055d.dll" (ByVal Channel As Integer)
Public up, down, lleft, rright As Boolean 'to keep track of which buttons are already pressed


Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim CardAddress As Integer
Dim h As Integer
CardAddress = 3

h = OpenDevice(3)
Label1.Text = "Card " + Str(h) + " connected"

End Sub

Private Sub MainForm_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown

Select Case e.KeyCode
Case Keys.A : Label1.ForeColor = Color.Red
Case Keys.L : Label2.ForeColor = Color.Red
Case Keys.Z : Label3.ForeColor = Color.Red
Case Keys.K : Label4.ForeColor = Color.Red
End Select

End Sub

Private Sub MainForm_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyUp

Select Case e.KeyCode
Case Keys.A : Label1.ForeColor = Color.Black
Case Keys.L : Label2.ForeColor = Color.Black
Case Keys.Z : Label3.ForeColor = Color.Black
Case Keys.K : Label4.ForeColor = Color.Black
End Select

End Sub


End Class

Please take advantage of the code tags.
What are you trying to achieve? Changing the labels colors works just fine for me like this:

Code:

---

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim CardAddress As Integer
        Dim h As Integer
        CardAddress = 3
        h = OpenDevice(3)
        Label1.Text = "Card " + Str(h) + " connected"
    End Sub

    Private Declare Function OpenDevice Lib "k8055d.dll" (ByVal CardAddress As Integer) As Integer
    Private Declare Sub SetDigitalChannel Lib "k8055d.dll" (ByVal Channel As Integer)
    Private Declare Sub ClearDigitalChannel Lib "k8055d.dll" (ByVal Channel As Integer)
    Public up, down, lleft, rright As Boolean

    Private Sub MainForm_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
        Select Case e.KeyCode
            Case Keys.A : Label1.ForeColor = Color.Red
            Case Keys.L : Label2.ForeColor = Color.Red
            Case Keys.Z : Label3.ForeColor = Color.Red
            Case Keys.K : Label4.ForeColor = Color.Red
        End Select
    End Sub

    Private Sub MainForm_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyUp
        Select Case e.KeyCode
            Case Keys.A : Label1.ForeColor = Color.Black
            Case Keys.L : Label2.ForeColor = Color.Black
            Case Keys.Z : Label3.ForeColor = Color.Black
            Case Keys.K : Label4.ForeColor = Color.Black
        End Select
    End Sub
End Class

---

Yeah, attempt 2 works for me as well. ?

EDIT: Oops. Nvm.

I was trying to have it change colour when the button is pressed and change back when the button is released, it's the changing back I'm having trouble with, sorry should have explained that

I copy & pasted your code, and also the releasing worked fine.

Thats annoying, I'm not at my computer anymore, I had to go to the lab so can't try again but I will later and I'll let you know how I get on, they were staying red when I was doing it, very annoying, I#ll let you know how I get on

If you want to use the arrow keys but not select controls on the form, override ProcessDialogKey but leave out the call to the MyBase Function. For example:

Code:

---

  Protected Overrides Function ProcessDialogKey(ByVal keyData As System.Windows.Forms.Keys) As Boolean
        Select Case keyData
            Case Keys.Up
                'do Up key action
            Case Keys.Down
                'do Down key action
                'etc.
        End Select
 
    End Function

---

This is a situation where you have to override a Sub or Function instead of handling the corresponding event.

cheers, BB

Didn't work either :). Tried that.

This also works and also still selects a new button:

vb Code:

        Select Case keyData
            Case Keys.Up : MsgBox("UP")
            Case Keys.Right : MsgBox("RIGHT")
            Case Keys.Down : MsgBox("DOWN")
            Case Keys.Left : MsgBox("LEFT")
        End Select
 
        Return (MyBase.ProcessDialogKey(keyData))
    End Function

---

This is an implicit call to MyBase.ProcessDialogKey:

Code:

---

Return (MyBase.ProcessDialogKey(keyData))

---

Try commenting it out. BB

Nice that seems to work (remember I am not the topic starter). But he must be able to register when the key is down and released again. So he uses the keydown and keyup events with character keys instead of the arrowkeys.

---

Once ProcessDialogKey has been overriden without a call to MyBase, the OP can code responses to the arrow keys in the KeyUp and KeyDown events; control selection will not happen. That is what ozirock wanted, isn't it? For example:

Code:

---

Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
        If e.KeyCode = Keys.Up Then MsgBox("Up key is pressed")
    End Sub

---

Incidentally, instead of leaving out the call to MyBase.ProcessDialogKey, it could go in an Else clause in the Case statement. That way the Tab and Enter keys would remain effective.

cheers, BB

Sorry you were right, I loaded up attempt two again and it worked, I don't know how I missed it, I'll work on the arrow keys some more during the week, I have a test in biomaterial's this week so I need to keep the head in the books for the time being. I'm going to make a website about this project and any others I do and I'd like to acknowledge you guy's help in it, would you like me to put your usernames as references i.e. gonzalioz from vbforums or actual names or nothing at all, thats cool too, if I dont get a reply I'll assume you don't want your name mentioned I think thats the fairest way.

I'll keep you guy's informed of how I get on with the arrow keys and post the code if I get it working.

Thanks for all the help guy's

Made a small video of it working, I got rid of the buttons from the form and just left the labels, here it is

Cool video! Nice to see the end result :). Where did you get that RC car and the thing connected to your laptop?

I picked up the rc car in Argos when I was younger, it's just a normal rc car. The other thing is a velleman k8055 usb interface board, I got that in maplin during the summer and put it together, it's a handy wee thing especially if your going for a type of robotics thing :)

Hi i've a K8055 and am interested how you interfaced the cars RC transmitter to the outputs, have you a circuit diagram of how you did it thanks.

Connect + to + and - to -


Just joking :P. I have no idea how this works. Really interested in it though. Last night I was thinking of all the possibilities. You could make a program to just turn on and off lights in your home from somewhere else using the internet, start up your computer, turn on the tv, turn on the water boiler or the coffee machine! Or develop some kind of energy saving application where you can set when you want the lights to turn on and off etc...

Coool. :)

I'm intending to hook the controller to this RC Amphibious tanks RC's transmitter I've just got from Maplins.
Then I'm going to mount a wireless spycam onto the turret and connect it to my PC's video input and then hopefully create a web based interface to control it over the internet.

To power light on and off you would use the usb board to switch relays, the relays would be capable of channeling mains electricity. The board wouldn't be up to that on is own but it is possible.
