Picturebox inside a Picturebox

I am using this code to move the PictInner inside of PictOuter to a certain point inside of it:

-------------------------------------------------------------------------
Private Sub PictOuter_MouseDown(Button As Integer, Shift As Integer, x As Single, Y As Single)
Dim pos As String

pos = Format(x / PictOuter.Width * 100, "0")
PictInner.left = PictOuter.Width * pos / 100
End Sub
-------------------------------------------------------------------------

My question is, how can I get the person to drag PictInner, instead of just being able to click somewhere in PictOuter, just like you would drag the sliderbar in a slider.

VB Code:

Private Sub picInner_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    Static blnBusy As Boolean
    If (Button And vbLeftButton) = vbLeftButton Then
        If blnBusy = False Then
            blnBusy = True
            picInner.Left = picInner.Left + X
            blnBusy = False
        End If
    End If
End Sub

Best regards

Can't you just say

VB Code:

If Button = vbLeftButton Then

Yes if the user only pressed down the left button but what if he pressed both the left and the right button?

Good point. Even though I don't do that, I guess it would be a stupidity check. :)

Okay that worked great, but I have another question. When I drag pictinner now, I can keep dragging it forever at runtime, even though it is inside of pictouter. How can I make it so that you cant' move it past the end of pictouter?

VB Code:

Private Sub picInner_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    Dim newX As Long
    Static blnBusy As Boolean
    If (Button And vbLeftButton) = vbLeftButton Then
        If blnBusy = False Then
            blnBusy = True
            newX = picInner.Left + X
            If newX < 0 Then
                newX = 0
            ElseIf newX > picOuter.ScaleWidth - picInner.Width Then
                newX = picOuter.ScaleWidth - picInner.Width
            End If
            picInner.Left = newX
            blnBusy = False
        End If
    End If
End Sub

Best regards

That worked perfect, except for one thing. It will only go from 0 to 70, and I need it to go from 0 to 100. Any way to do this?

When you calculate the position you should use the following formula:

VB Code:

Dim nPos As Long
nPos = picInner.Left / (picOuter.ScaleWidth - picInner.Width) * 100

Sorry, I stayed up all night and now I can't think. I am using this inner outer thing as a balance between the right and the left. How can I make it so that when it is in the middle, volleft and volright = 100, and when it gets to the end of the left side the volright is at 0, just the same when it gets to the end of the right side volleft will be 0. I dont care if in order for volright to be at 0, volleft needs to be at 200 or something, it doesnt matter, just as long as when it is all the way to the left volright is at 0. Sorry about the carry on sentences, but I am struggling to even keep my eyes open right now.

-----------------------------------------------------------
Private Sub PictInnerBalance_MouseMove(Button As Integer, Shift As Integer, x As Single, Y As Single)
Dim volright As Long
Dim volleft As Long
Dim pos As String
Dim newX As Long
Static blnBusy As Boolean


If (Button And vbLeftButton) = vbLeftButton Then
If blnBusy = False Then
blnBusy = True
newX = PictInnerBalance.left + x
If newX < 0 Then
newX = 0
ElseIf newX > PictOuterBalance.ScaleWidth - PictInnerBalance.Width Then
newX = PictOuterBalance.ScaleWidth - PictInnerBalance.Width
End If
PictInnerBalance.left = newX
pos = PictInnerBalance.left / (PictOuterBalance.ScaleWidth - PictInnerBalance.Width) * 200
volright = pos
volleft = pos
label1.Caption = "Left: " & volleft & "%" & " Right: " & volright & "%"
blnBusy = False
End If
End If
End Sub

I put my code in there just for the hell of it, you will probably change it alot which is okay, since it doesnt work. :D

You only have to change your code on two lines (the bold ones)

VB Code:

Private Sub pictInnerBalance_MouseMove(Button As Integer, Shift As Integer, x As Single, Y As Single)
    Dim volright As Long
    Dim volleft As Long
    Dim pos As String
    Dim newX As Long
    Static blnBusy As Boolean
    
    
    If (Button And vbLeftButton) = vbLeftButton Then
        If blnBusy = False Then
            blnBusy = True
            newX = pictInnerBalance.Left + x
            If newX < 0 Then
                newX = 0
            ElseIf newX > pictOuterBalance.ScaleWidth - pictInnerBalance.Width Then
                newX = pictOuterBalance.ScaleWidth - pictInnerBalance.Width
            End If
            pictInnerBalance.Left = newX
            pos = pictInnerBalance.Left / (pictOuterBalance.ScaleWidth - pictInnerBalance.Width) * 200
            
            [b]volright = 200 - pos[/b]
            [b]volleft = 200 - volright[/b]
            Label1.Caption = "Left: " & volleft & "%" & " Right: " & volright & "%"
            blnBusy = False
        End If
    End If
End Sub

Thats almost perfect. They are both 100% when they are in the middle, which I need, and when it goes to the left it is at 0%, and when it goes to the right it is at 0%. The problem, is that when it is all the way to the left, right displays 200%, and I only want it to display 100%. That means, I think, that I am going to have to do something like this:

Label1.Caption = "Left: " & (volleft - 50) & "%" & " Right: " & (volright - 50) & "%"


except replace the "50" with whatever equation will make the two labels display 50% while in the middle, and 0% while at the opposite end of the spectrum. Feel free to do whatever you want to try and fix this problem, but try and only use label1.caption because if you change anything else then the volume will not only display 50% while in the middle, but it will actually be 50%, instead of being 100% which it needs to be. Thank you.

No simply change your code to something like this:

VB Code:

volright = 200 - pos
volleft = 200 - volright
[b]If volright > 100 Then
    volright = 100
ElseIf volleft > 100 Then
    volleft = 100
End If[/b]
Label1.Caption = "Left: " & volleft & "%" & " Right: " & volright & "%"
