Créer une barre de progression en VBA Excel

Ici est très bien commenté version du code pour vous:

Sub Main()
'   Inserts random numbers on the active worksheet
    Dim Counter As Integer
    Dim RowMax As Integer, ColMax As Integer
    Dim r As Integer, c As Integer
    Dim PctDone As Single


    If TypeName(ActiveSheet) <> "Worksheet" Then Exit Sub
    '- if this subroutine is ran on a sheet that is not called "Worksheet" then exit
    '-- change 'Worksheet' to whatever sheet you want the progress bar on

    Cells.Clear
    '- clear all cells in active worksheet

    Application.ScreenUpdating = False
    '-disables updating the screen in the for loop that follows
    '- that way if we are editing 1000 cells int he workbook it only needs to update them at the end when
    '- this is set back to true

    Counter = 1 '- counter counts what cell we are on
    RowMax = 100 '- this is how many rows will be filled with data
    ColMax = 25 '- this is how many columns will be filled with data

    '- note that Rowmax * ColMax = 2,500 co counter will go from 1 to 2,500

    For r = 1 To RowMax
        '-for each row 1 to 100 we will loop through the 25 columns to add the random number
        For c = 1 To ColMax
            '- enter a random number into the cell we are on (Cells(r,c))
            Cells(r, c) = Int(Rnd * 1000)
            '- +1 to the coutner so we can count which cell we ar eon out of 2,500
            Counter = Counter + 1
        Next c
        '- after finishing each column but before starting the next row
        '- check what percent done we are (to update the userform)
        PctDone = Counter / (RowMax * ColMax)

        '- Edit the progressbar called "UserForm1" (already exists in workbook)
        With UserForm1
            'Userform has 2 items in it a Label called 'FrameProgress' and a onject called 'LabelProgress'
            'Change the text in the Label called 'FrameProgress' to display the percent done we calculated earlier
            .FrameProgress.Caption = Format(PctDone, "0%")
            ' Resize the object called 'LabelProgress' to be X perxent of the width of the previous label (minus 10 to leave room on the edge)
            ' - where X is the percent we are done
            .LabelProgress.Width = PctDone * (.FrameProgress.Width - 10)
        End With
'       The DoEvents statement is responsible for the form updating
        DoEvents
    Next r
    '- exit form when it is at 100%
    Unload UserForm1
End Sub

les seules parties du code qui sont utiles pour vous de noter que, si c'est une boucle est de savoir quel est le pourcentage, il est fait, puis de les utiliser pour mettre à jour le formulaire.

Si vous avez eu beaucoup de code, il vous suffit de mettre le suivant tout au long de l' (en supposant que vous créez le formulaire)

Sub Example()
    'wait a few seconds
    Application.Wait (100000)
    'your code goes here instead of .wait

    PctDone = 0.3
    With UserForm1
        'Userform has 2 items in it a Label called 'FrameProgress' and a onject called 'LabelProgress'
        'Change the text in the Label called 'FrameProgress' to display the percent done we calculated earlier
        .FrameProgress.Caption = Format(PctDone, "0%")
        ' Resize the object called 'LabelProgress' to be X perxent of the width of the previous label (minus 10 to leave room on the edge)
        ' - where X is the percent we are done
        .LabelProgress.Width = PctDone * (.FrameProgress.Width - 10)
    End With
    'The DoEvents statement is responsible for the form updating
    DoEvents

    Application.Wait (100000)
    'your code goes here instead of .wait

    PctDone = 0.6
    With UserForm1
        .FrameProgress.Caption = Format(PctDone, "0%")
        .LabelProgress.Width = PctDone * (.FrameProgress.Width - 10)
    End With
    DoEvents

    Application.Wait (100000)
    'your code goes here instead of .wait

    PctDone = 0.9
    With UserForm1
        .FrameProgress.Caption = Format(PctDone, "0%")
        .LabelProgress.Width = PctDone * (.FrameProgress.Width - 10)
    End With
    DoEvents

    Application.Wait (100000)
    'your code goes here instead of .wait

End Sub
