Insertar un Picturebox y un Timer para este ejemplo, luego pegar el siguiente

Código:

Olvidate del timer..

Código:
Const T = 100 'En base a un Total

Private Function Porciento(Cantidad As Long, Total As Long) As Integer
    Porciento = Cantidad / Total * 100
End Function

Private Sub Command1_Click()
    Static C As Long
    C = C + 1
    ProgBar Picture1, CLng(Porciento(C, T)), vbWhite, vbBlue, vbBlack, True, 0
End Sub

thx ^^
ahora lo pruebo Numerito xD

un abraz0 ;)


-------- EDIT --------

Observacion:
Cambiar este code por

Código:
Private Sub Command1_Click()
    Static C As Long
    C = C + 1
    ProgBar Picture1, CLng(Porciento(C, T)), vbWhite, vbBlue, vbBlack, True, 0
End Sub
este otro, asi si llega a 100 no sigue sumando ^^
Código:
Private Sub Command1_Click()
    Static C As Long
    If C < 100 Then
    C = C + 1
    End If
    ProgBar Picture1, CLng(Porciento(C, T)), vbBlue, vbRed, vbYellow, True, 0
End Sub


che gracias x el code
ta bastante bueno y me viene de 10 (yo que odio las progress del vb xD)

cya

jaja - tienes razón se me fue ese detalle..
ahora ya tienes la idea de como se calcula un progreso. por eso te puse la funcion del porciento ;)
