I have prbably a silly question but I recently wrote code to loop through 8
bitmaps and display them in an image box.the code is

Private Sub Image2_Click()
Dim index As Integer

Show Image2
For i = 0 To 8
'index = index + 1
Print i
'Show; Image2.Picture
'index = index + 1
'Image2.Visible = True
For a = 1 To 1000000
Image2 = Image1(i)
Next a
'index = index + 1
'index = index
Next i
End Sub
I made a matrix of 8 bitmaps on form and one empty image box.but for some
reason it only loops through 5 or 6 and then jumps to 8 .What am I doing
wrong.

The For loop above.... are you doing this for some kind of time delay? If
so, note that your "1000000" will take different amounts of time depending
on the CPU/RAM/etc the end user has. Also, you're assigning that image
1000000 times... no flicker? It's probably happening too fast to flicker.

If you start a new Project, drop a timer on the form (Timer1), drop an array
of 8 image controls (Image1(0-7)), another Image control (Image2) and 2
command buttons, called cmdGo and cmdStop, you should be able to see
"another way" of doing what you're trying to do.
'=============
Option Explicit

Private Sub cmdGo_Click()
Timer1.Tag = "" 'clear the "Flag"
Timer1.Enabled = True
DoEvents
cmdGo.Enabled = False
cmdStop.Enabled = True
End Sub

Private Sub cmdStop_Click()
Timer1.Tag = "STOP" 'set the "Flag"
End Sub

Private Sub Form_Load()
Timer1.Enabled = False
Timer1.Interval = 500 '1/2 sec between pics - change this at will
Timer1.Tag = "STOP"
cmdStop.Enabled = False
End Sub

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
If UnloadMode = vbFormControlMenu Then
If Timer1.Tag <> "STOP" Then
MsgBox "Click Stop first!"
Cancel = True
End If
End If
End Sub

Private Sub Timer1_Timer()
Static iElement As Integer

If Timer1.Tag = "STOP" Then
Timer1.Enabled = False
cmdGo.Enabled = True
cmdStop.Enabled = False
Else
Debug.Print "Showing image #" & iElement
Image2.Picture = Image1(iElement).Picture
iElement = iElement + 1
If iElement > Image1.UBound Then
iElement = 0
End If
End If

End Sub

click box once ,first pic,click again second pic etc.

Very similar code.
