سلام - امروز می خوایم یه کاری روی Desktop انجام بدیم - با سورس زیر تمام آیکونهای روی صفحه از سمت چپ چیده می شن.

کد ماژول :

Option Explicit

Private Declare Function GetWindow Lib "user32" (ByVal hwnd As Long, ByVal wCmd As Long) As Long
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Long) As Long
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long

Private Const GW_CHILD = 5
Private Const LVA_ALIGNLEFT = &H1
Private Const LVM_ARRANGE = &H1016

حالا یک Command با نام Command1 به فرم اضافه کرده و : 

Private Sub Command1_Click()
    Dim HWnd1 As Long
    Dim HWnd2 As Long
    Dim MER As Long

    HWnd1 = FindWindow("Progman", vbNullString)
    HWnd2 = GetWindow(HWnd1, GW_CHILD)
    HWnd1 = GetWindow(HWnd2, GW_CHILD)
    MER = SendMessage(HWnd1, LVM_ARRANGE, LVA_ALIGNLEFT, 0)
End Sub
