How to use PROGRESSBAR object in visual basic 6
VBcoders
' add two command button to the form
' Let the first command button be command1 or any desired name
' from the property change the caption to Foreward
' let the second command button be command2
' From the property change the caption to End
' Fimally add the Microsoft Window common Control 6.0
' from Project Menu bar and menu item Component
' Add the ProgressBar control
' Change the object name to countingbar
Dim num As Long
Private Sub Command1_Click()
CountingBar_Click ' call the progressbar routine
End Sub
Private Sub Command2_Click()
DoEvents ' enable mouse while processing clic
End ' terminate the program
End Sub
Private Sub CountingBar_Click()
'CountingBar.Value = CountingBar.Value = Int(num / CountingBar.Max)
'Command1.Caption = "Reverse"
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
CountingBar.Max = 20000 ' is the maximum record/file
' as the case may be
Do While num <= CountingBar.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 <= CountingBar.Max Then
CountingBar.Value = num ' assign the counter to the
' progress bar value
' it is this property that realy does the animation
End If
Form1.Caption = num & " Number At " & Str(Int((num / CountingBar.Max) * 100)) + " %"
' display the progress 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 progressbar
num = 20000 ' The highest value or maximun value
CountingBar.Min = 1 ' get the minimum value of the
' progress bar
Do While num >= CountingBar.Min
num = num - 1 'start decreasing the progress
' bar from the right hand side
If num >= CountingBar.Min Then
CountingBar.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 / CountingBar.Max) * 100)) + " %"
' display the progress 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
