' Add one label for the slider
' Add Microsoft common control 6.0 from Component menu item
' from the Project menu bar
' Finally add two command buttons
'....The first command button should be captioned Forward and
' the other End
Dim num As Long
Private Sub Command1_Click()
'call the slider routine
Slider1_Click
End Sub
Private Sub Command2_Click()
DoEvents ' enable mouse while processing clic
End ' terminate the program
End Sub
Private Sub Slider1_Click()
Dim t As Double, m(20000) As Double
' you can read the content of a file, process the file, process an image
' and lot more
' or using any other routine that requires keeping
' the user alive
If Command1.Caption = "Foreward" Then
num = 0
Slider1.Max = 20000 ' is the maximum record/file
' as the case may be
Do While num <= Slider1.Max - 1
' ASSUMING you want to read the content of a file or process
' a file the code should be here for example
'If EOF(1) Then Exit Sub
'Input #1, m,.....
'.......more codes for the processing continue within
' the do loop
num = num + 1 ' increament the counter
If num <= Slider1.Max Then
Slider1.Value = num ' assign the counter to the
' slider bar value
' it is this property that realy does the animation
End If
Form1.Caption = num & " Number At " & Str(Int((num / Slider1.Max) * 100)) + " %"
' display the slider bar percentage in the form's caption
DoEvents ' enable mouse while processing click
Loop
' Close
Command1.Caption = "Reverse"
' toggles the push button
Else
' reverse the direction of the sliderbar
num = 20000 ' The highest value or maximun value
Slider1.Min = 1 ' get the minimum value of the
' slider bar
Do While num >= Slider1.Min
num = num - 1 'start decreasing the slider
' bar from the right hand side
If num >= Slider1.Min Then
Slider1.Value = num
End If
'For h = 1 To 10000000: Next h
' there may be a need for a delay if the operation is small
Form1.Caption = num & " Number At " & Str(Int((num / Slider1.Max) * 100)) + " %"
' display the slider bar percentage in the form's caption
DoEvents ' enable mouse while processing clic
Loop
Command1.Caption = "Foreward" ' toggles the caption again
' base on the operation
End If
End Sub
