If button is clicked then....

How do I check if a button is clicked?

The Click() event will fire when the button is clicked.

Code:

---

Private Sub Command1_Click()
    MsgBox "Command1 was clicked"
End Sub

---

use the return value of the message box...it tells you which button was clicked.

Code:

---

Private Sub Command1_Click()
    Dim Response As Integer
   
    Response = MsgBox("Click a button", vbOKCancel)
   
    If Response = vbOK Then
        MsgBox "you clicked ok"
    Else
        MsgBox "you clicked cancel"
    End If
End Sub

---

What i ment was something else. Here's some code:

Code:

---

Private Sub Command1_Click()

Do
ani = ani + 1
If ani = 7 Then ani = 1
box1.Picture = MyPic(ani)
box2.Picture = MyPic(ani)
box3.Picture = MyPic(ani)
'this place right here
Loop

proceed:
Randomize
a1 = Int((6 * Rnd) + 1)
a2 = Int((6 * Rnd) + 1)
a3 = Int((6 * Rnd) + 1)
box1.Picture = MyPic(a1)
box2.Picture = MyPic(a2)
box3.Picture = MyPic(a3)

End Sub

---

You see, I'm already in a button. And this is a button for a slot machine, so it activates the looping of the fruit pictures. But I want to use the same button to stop the looping also. So at the place I marked (see code) I want something like:

Code:

---

if command1 = clicked then goto proceed

---

U see what I mean?

Oops, I was distracted by the code in your footer and thought you wanted to know how you know which button is clicked in response to a message box!

Megatron is right...the Click event for the button the user pushes will fire for a button you put on a form.

To find out what button they pushed in response to a MsgBox, use my code. You specify what buttons will be available in the message box function (in my example the buttons will be Ok and Cancel).

Some button constants are:
vbOk, vbCancel, vbYes, vbNo, vbRetry, vbAbort, vbIgnore

Still not what I'm looking for. Please scroll two messages
upwards and read my reply. Then you'll see what I mean..."
:rolleyes:

I don't think you can do that. You are already in the Click event...there is no way to click the button again if the event is still running.

You should try something else, like using a timer control and placing the code to move the pictures there.

Then you can set the Timer1.Interval property from the command button. This is about as close to Multi-Threading as you can get with VB without causing a bunch of headaches.

So, put the code to move the pictures in the timer control. Then in the click event of the button type this:

Code:

---

Private Sub Command1_Click()
    If Timer1.Interval = 0 Then
        Timer1.Interval = 100 ' set to whatever speed you want
    Else
        Timer1.Interval = 0 ' This stops the timer, and therefore stops the pictures
    End If
End Sub

---

Private Sub Command1_Click()
If Command1.text = "Go" ThenDo
ani = ani + 1
If ani = 7 Then ani = 1
box1.Picture = MyPic(ani)
box2.Picture = MyPic(ani)
box3.Picture = MyPic(ani)
'this place right here
Loop

proceed:
Randomize
a1 = Int((6 * Rnd) + 1)
a2 = Int((6 * Rnd) + 1)
a3 = Int((6 * Rnd) + 1)
box1.Picture = MyPic(a1)
box2.Picture = MyPic(a2)
box3.Picture = MyPic(a3)
Command1.text = "Stop"

Else
Stop Spinning
Comand1.text = "Go"

End If
End Sub


Or change the icons on the buttons or whatever. Better yet put the spin and the stop code in sepearate procedures then you can also add menu items or a button to call the procedures.

You may have to add DoEvents to your loop to release the User interface.

Code:

---

Option Explicit

Private Sub Command1_Click()
    Dim PicNum1 As Integer
    Dim PicNum2 As Integer
    Dim PicNum3 As Integer
   
    If Timer1.Interval = 0 Then
        Command1.Caption = "Stop"
        Timer1.Interval = 100 ' set to whatever speed you want
    Else
        Command1.Caption = "Start"
        Timer1.Interval = 0
       
        ' One last move of the pictures...
        Randomize
   
        PicNum1 = Int((6 * Rnd) + 1)
        PicNum2 = Int((6 * Rnd) + 1)
        PicNum3 = Int((6 * Rnd) + 1)
       
        box1.Picture = MyPic(PicNum1)
        box2.Picture = MyPic(PicNum2)
        box3.Picture = MyPic(PicNum3)
    End If
End Sub

Private Sub Form_Load()
    Timer1.Interval = 0
    Command1.Caption = "Start"
End Sub

Private Sub Timer1_Timer()
    Static ani As Integer
   
    ' Change pictures
    ani = ani + 1
    If ani = 7 Then ani = 1
    box1.Picture = MyPic(ani)
   
    ani = ani + 1
    If ani = 7 Then ani = 1
    box2.Picture = MyPic(ani)
   
    ani = ani + 1
    If ani = 7 Then ani = 1
    box3.Picture = MyPic(ani)
End Sub

LOL
"Hyperactive Member"?
Wonder how you got that title!

Ok, So, in the place you specified, you want to determine if the button had been clicked previously and if so, goto PROCEED:

Let's see if this works ...

Code:

---

Private Sub Command1_Click()
    Do
        ani = ani + 1
        If ani = 7 Then ani = 1
        box1.Picture = MyPic(ani)
        box2.Picture = MyPic(ani)
        box3.Picture = MyPic(ani)
        If Command1.Tag = "CLICKED" Then
            Command1.Tag = ""
            Goto PROCEED
        End If
    Loop

PROCEED:
    Randomize
    a1 = Int((6 * Rnd) + 1)
    a2 = Int((6 * Rnd) + 1)
    a3 = Int((6 * Rnd) + 1)
    box1.Picture = MyPic(a1)
    box2.Picture = MyPic(a2)
    box3.Picture = MyPic(a3)
    If Command1.Tag <> "CLICKED" Then
        Command1.Tag = "CLICKED"
    End If
End Sub

---

Code:

---

Private Sub Command1_Click()
   
    Static blnClicked As Boolean

    Debug.Print "Clicked=" & blnClicked
    blnClicked = Not blnClicked

End Sub

This is what you said. But what if I took a second button, so I have two buttons, one for starting and one for stopping. Is that possible?

Try making a second button. Hide it.
First button click/hide and show second.

Just swap them back and forth.

The user thinks it is the same button.

I already tried that, bu how do I make the second button
stop de looping in the procedure of the first button and
proceed with the rest of the procedure in the first button?
Know what I'm sayin'?

In your loop, place a DoEvents. In your second button click routine,
make it set a boolean. In your loop do a Do While the boolean is true (or false, whatever).
Then toggle the boolean before you quit your routine so you can use it again.

I'm not quite sure what u mean, but I'll give it a try...

I think he means something like this:

Code:

---

Option Explicit

' This tells whether the images are changing or not
Private ImagesChanging As Boolean

Private Sub cmdStart_Click()
    ' Set the global variable = True
    ImagesChanging = True
   
    ' Hide the start button and show the stop button
    cmdStart.Visible = False
    cmdStop.Visible = True
   
    ' Move your images around while the global variable is true
    Do
        ' Move your images around here
        ' ....
        ' ....
       
        DoEvents  ' Don't forget the DoEvents!
    Loop While ImagesChanging
   
End Sub

Private Sub cmdStop_Click()
    ' Set the global variable = False.  This should stop images from changing
    ImagesChanging = False
   
    ' Hide the stop button and show the start button again
    cmdStart.Visible = True
    cmdStop.Visible = False
End Sub

---

you can come through with one button. try somethig like this:

Code:

---

Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

Private mbytCounter As Byte
Private mblnLoop As Boolean

Private Sub Form_Load()

    With Me
        .ScaleMode = vbPixels
        .AutoRedraw = True
    End With

    cmdRun.Caption "&Start"

    DoLoop False
    mbytCounter = 1
    SetCounter mbytCounter
   
End Sub

Private Sub cmdRun_Click()
   
    DoLoop (Not mblnLoop)
   
End Sub

Private Sub DoLoop(ByRef Run As Boolean)

    mblnLoop = Run
   
    If mblnLoop Then
        cmdRun.Caption = "&Stop"
    Else
        cmdRun.Caption = "&Start"
    End If
   
    RunLoop
   
End Sub

Private Sub RunLoop()

    Do While mblnLoop
        SetCounter mbytCounter
        Sleep 100
        DoEvents
    Loop
   
End Sub

Private Sub SetCounter(ByRef Counter As Byte)

    With Me
        .Cls
        .CurrentX = 100
        .CurrentY = 100
    End With
   
    Me.Print Counter
   
    If Counter = 20 Then
        Counter = 1
    Else
        Counter = Counter + 1
    End If
   
End Sub

When you click on the button first time then change some properties of that button like Caption, then you can read that property to check whether you clicked or not e.g.,
beginning assume that your command button caption = "Click here"

Private Sub Command1_Click()
if(Command1.Caption = "Click here") Then
'do all your code here when you click first time
Command1.Caption = "Clicked once" ' Something like this
Elseif(Command1.Caption = "Clicked once") Then
' Do your all other code here when you click second time
End if
End Sub

You are correct :) but still this question may remains the same right. Suppose still may have doubts for many developers / students

The same answer was already given in post #8
