Timer Code

VB Code:

Dim tmrVal As Long
Dim BinVal As String
 
Private Sub tmrCount_Timer()
    BinVal = DecToBin(tmrVal)
    For l = -7 To 0
        If Mid(BinVal, l + 8, 1) = "1" Then
            If shpLED(l + 8).BackColor = &H80& Then
                pbxLedDisplay_MouseUp 0, 0, 200 + ((l + 7) * 360), 250
            End If
        ElseIf Mid(BinVal, l + 8, 1) = "0" Then
            If shpLED(l + 8).BackColor = &HFF& Then
                pbxLedDisplay_MouseUp 0, 0, 200 + ((l + 7) * 360), 250
            End If
        End If
    Next
    If TimerVal = 255 Then
        TimerVal = TimerVal - 255
    Else
        tmrVal = tmrVal + 1
    End If
    MsgBox tmrVal
End Sub

Anyone have any ideas why at the end of every timer interval (100ms) tmrVal always equals 1? this sub is the only place tmrVal is being used!

Your a victim of brain melting... take a break

VB Code:

If [b]TimerVal[/b] = 255 Then
        [b]TimerVal[/b] = TimerVal - 255
    Else
        [b]tmrVal[/b] = [b]tmrVal[/b] + 1
    End If

Oh no, sorry, the reason was that I WAS using that, but I had already commented it out, I only took out the single quotes because it was what I originally had...

RIGHT now my code looks like this:

VB Code:

'If TimerVal = 255 Then
    '    TimerVal = TimerVal - 255
    'Else
        tmrVal = tmrVal + 1
    'End If

Very sorry about that!

You must be setting tmrval = 1 somewhere else in your code...

Hit CTRL-F , enter tmrval , and click Find Next....

The only other place is here

VB Code:

Private Sub MDIForm_Load()
    ResetSubWindows Me
    SetPBarPos Me
    tmrVal = 0
End Sub

But thats the form load :rolleyes:

Well, if you meant to declare tmrval as global variable, then use

VB Code:

Public tmrVal As Long

in your parent form....

I imagine if you have OPTION EXPLICIT at top of all your forms... the IDE would tell you the variable was not declared..

Well I don't think I need it public... and it doesn't seem to change the end result anyway :rolleyes:

The problem is where your declaring tmrVal....

If you declare in the parent form as so: Dim tmrVal As Long , then incrementing tmrval in your child form won't affect that value... since its only available to the parent form, not the child form (MDIForm).... if you need to use the tmrVal in the parent form, declare it as Public...

You don't get an error when you use the code in your MDIFORM because the compiler changes this code:

VB Code:

Private Sub Timer1_Timer()
tmrval = tmrval + 1
MsgBox tmrval
End Sub

to read

VB Code:

Private Sub Timer1_Timer()
Dim tmrval as Long  'initializes a long data type, setting it to 0.
tmr=tmrval + 1        'adds 1
msgbox tmrval        'will always be 1
End Sub

You see... you don't have Option Explicit, so the compiler is letting you get away with not declaring a variable, so it creates one everytime the _Timer Event is called... and it initializes it to zero, and you add 1 to it... so its always one.

To get around this... since you don't need it global... declare Dim tmrVal As Long at the top of your MDIFORM... then the compiler knows that this variable will persist and keep its value...

Use OPTION EXPLICIT at the top of all your forms... and it will become clear why it worked... (or go to TOOLS...EDITOR... REQUIRE VARIABLE DECLARATION)

:confused: Ok, well, all of this is being done in the MDIForm, Here, I'll post all relevant code...


This is all in my MDIForm

VB Code:

Option Explicit
Dim tmrVal As Long
 
Private Sub MDIForm_Load()
    ResetSubWindows Me
    SetPBarPos Me
End Sub
 
Private Sub pbxLedDisplay_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
    Dim s As Shape
    Dim i As Integer
    Set s = ShapeHitTest(X, Y)
    If Not s Is Nothing Then
        If shpLED(s.Index).BackColor = &H80& Then
            shpLED(s.Index).BackColor = &HFF&
            lblBinCode = Mid(lblBinCode, 1, (s.Index * 2) - 1) & Replace(lblBinCode, "0", "1", s.Index * 2, 1)
        ElseIf shpLED(s.Index).BackColor = &HFF& Then
            shpLED(s.Index).BackColor = &H80&
            lblBinCode = Mid(lblBinCode, 1, (s.Index * 2) - 1) & Replace(lblBinCode, "1", "0", s.Index * 2, 1)
        End If
    End If
    Dim store As String
    For i = 1 To 8
        store = store & Mid(lblBinCode, i * 2, 1)
    Next
    lblBinCode = Mid(lblBinCode, 1, 19) & BinToDec(store)
End Sub
 
Private Function ShapeHitTest(ByVal X As Single, ByVal Y As Single) As Shape
    Dim c As Control
    For Each c In Controls
        If TypeOf c Is Shape Then
            If ((X >= c.Left) And (X <= c.Left + c.Width)) And ((Y >= c.Top) And (Y <= c.Top + c.Height)) Then
                Set ShapeHitTest = c
                Exit Function
            End If
        End If
    Next
End Function
 
Private Sub tmrCount_Timer()
    Dim l As Integer
    For l = -7 To 0
        If Mid$(BinToDec(tmrVal), l + 8, 1) = "1" Then 'When I remove the BinToDec() from here...
            If shpLED(l + 8).BackColor = &H80& Then
                pbxLedDisplay_MouseUp 1, 0, 200 + ((l + 7) * 360), 225
            End If
        ElseIf Mid$(BinToDec(tmrVal), l + 8, 1) = "0" Then 'and from here, the counter works fine
            If shpLED(l + 8).BackColor = &HFF& Then
                pbxLedDisplay_MouseUp 1, 0, 200 + ((l + 7) * 360), 225
            End If
        End If
    Next
    If tmrVal = 255 Then
        tmrVal = tmrVal - 255
    Else
        tmrVal = tmrVal + 1
    End If
    MsgBox tmrVal 'This always says 1
End Sub

And this is all in a module

VB Code:

Public Function BaseTwoCheck(DecimalCode As Long) As Long
    i = 0
    num = 0
    Do Until DecimalCode <= num
        num = num + 2 ^ i
        i = i + 1
    Loop
    BaseTwoCheck = i - 1
End Function
 
Public Function DecToBin(DecimalCode As Long) As String
    If DecimalCode = 0 Then
        DecToBin = "00000000"
        Exit Function
    End If
    For X = BaseTwoCheck(DecimalCode) To 0 Step -1
        Y = 2 ^ X
        If DecimalCode > (Y - 1) Then
            DecToBin = DecToBin & "1"
            DecimalCode = DecimalCode - Y
        Else
            DecToBin = DecToBin & "0"
        End If
    Next
    DecToBin = Format$(DecToBin, "00000000")
End Function

Edit: And I always use Option Explicit, I just didn't add it before :rolleyes:

Sorry, from initial impressions, it looked like you were simply just declaring tmrval in the wrong form. I must admit I'm stumped....
as long as you did Find Next on tmrval for the entire project, I can't understand why calling a module level function would reset tmrval to zero... when I simulated the same setup...a form that loads a MDIFORM with a timer, and calls the Dec2Bin function in a module..... the counter did not reset... so its something in your app...

Don't ask me how, but I fixed it... (rewrote nearly all of it) But thanks for all your help :D
