API制作窗体状态栏，这个程序是以下面VB代码创建一个简单的状态栏程序而来的

' Dim hWndBar As Long               ;状态栏句柄
' Private Const IDC_STATBAR As Long = &H2005        ’状态栏ID
' Private Sub Command1_Click()
' Dim ret As Boolean
' ret = CreateStatBar(Me.hwnd, IDC_STATBAR, hWndBar)
' If ret = True Then
' MsgBox "创建状态栏成功!"
' Else
' MsgBox "创建状态栏失败:-(!", 48
' End If
' End Sub

' Private Sub Command2_Click()
' SetBarText hWndBar, 1, "Create StatusBar Demo:-)!"
' End Sub
' ’移动状态栏
' Private Sub Form_Resize()
' MoveStatWindow hWndBar
' End Sub

' 然后添加一个模块，模块里写上代码:
' Private Const WS_CHILD As Long = &H40000000             ’WS_CHILD 和WS_VISIBLE是必需函数
' Private Const WS_VISIBLE As Long = &H10000000
' Private Const WM_USER As Long = &H400
' Private Const SB_SETPARTS As Long = (WM_USER + 4)       ’这两个常数在VB自带的api查询器里没有，需要手工添加
' Private Const SB_SETTEXTA As Long = (WM_USER + 1)
' Private Declare Function CreateStatusWindow Lib "comctl32.dll" (ByVal style As Long, ByVal lpszText As String, ByVal hwndParent As Long, ByVal wID As Long) As Long
' Private Declare Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByRef lParam As Any) As Long
' Private Declare Function MoveWindow Lib "user32.dll" (ByVal hwnd As Long, ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal bRepaint As Long) As Long

' ’                       创建状态栏
' ’函数说明：
' ’ParenthWnd    状态栏所属的句柄
' ’IDC_STATBAR   状态栏的ID号，用于对状态栏的单击之类的操作
' ’hBarWin       函数返回状态栏的句柄
' ’szText        要显示的信息

' ’---------------------------------------------------
' Function CreateStatBar(ParenthWnd As Long, IDC_STATBAR As Long, hBarWin As Long, Optional szText As String = "Demo") As Boolean
' Dim ret As Long                 ’返回值
' Dim bar(0 To 1) As Long         ’分栏的各项位置
' Dim szbar As Long               ’分栏的数目

' ’-------------------------------------------------------
' ’定义数组
' bar(0) = 235                    ’第一栏宽度为245
' bar(1) = -1                     ’-1表示后面的分为一栏

' ’-------------------------------------------------------
' ret = CreateStatusWindow(WS_CHILD Or WS_VISIBLE, ByVal szText, arenthWnd, IDC_STATBAR)     ’创建状态栏
' szbar = 2
' If ret = 0 Then                 ’如果创建失败则退出过程
' CreateStatBar = False
' Exit Function
' End If
' hBarWin = ret                   ’返回状态栏的句柄
' If szbar > 1 Then               ’因为默认就是分一栏所以，这里判断为大于1就是分栏
' SendMessage hBarWin, SB_SETPARTS, szbar, bar(0)    ’分栏
' End If
' CreateStatBar = True            ’创建成功返回真值

' ’移动状态栏
' ’----------------------------
' Sub MoveStatWindow(hBar As Long)
' If hBar Then                ’如果状态栏句柄不为0则移动
' Call MoveWindow(hBar, 0, 0, 0, 0, True)
' End If
' End Sub
' ’------------------------------
' ’在指定栏上显示信息
' ’hBar 为状态栏的句柄
' ’szbar 指定要在哪一栏显示信息，从0开始计，也就是说，如果分两栏，我们要在第二栏里显示信息，szbar就设置为1
' ’szText 要显示的信息
' ’-------------------------------
' Sub SetBarText(hBar As Long, szbar As Long, strText As String)
' SendMessage hBar, SB_SETTEXTA, szbar, ByVal strText
' End Sub
