^^ 创建setup类型的进度条（vb6） ^^
- 新建一个工程
- 增加一个picture box和command button
加入下面的代码：
Dim tenth As Long
'条件编译
#If Win32 Then
Private Declare Function BitBlt Lib "gdi32" _
(ByVal hDestDC As Long, ByVal x As Long, ByVal y As Long, _
ByVal nWidth As Long, ByVal nHeight As Long, _
ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, _
ByVal dwRop As Long) As Long
#Else
Private Declare Function BitBlt Lib "GDI" (ByVal hDestDC As _
Integer, ByVal x As Integer, ByVal y As Integer, ByVal nWidth _
As Integer, ByVal nHeight As Integer, ByVal hSrcDC As Integer, _
ByVal xSrc As Integer, ByVal ySrc As Integer, ByVal dwRop As _
Long) As Integer
#End If
Sub UpdateStatus(FileBytes As Long)
'--------------------------------------------------------------------
' 更新Picture1 status bar
'--------------------------------------------------------------------
Static progress As Long
Dim r As Long
Const SRCCOPY = &HCC0020
Dim Txt$
progress = progress + FileBytes
If progress > Picture1.ScaleWidth Then
progress = Picture1.ScaleWidth
End If
Txt$ = Format$(CLng((progress / Picture1.ScaleWidth) * 100)) + "%"
Picture1.Cls
Picture1.CurrentX = _
(Picture1.ScaleWidth - Picture1.TextWidth(Txt$)) \ 2
Picture1.CurrentY = _
(Picture1.ScaleHeight - Picture1.TextHeight(Txt$)) \ 2
Picture1.Print Txt$
Picture1.Line (0, 0)-(progress, Picture1.ScaleHeight), _
Picture1.ForeColor, BF
r = BitBlt(Picture1.hDC, 0, 0, Picture1.ScaleWidth, _
Picture1.ScaleHeight, Picture1.hDC, 0, 0, SRCCOPY)
End Sub
Private Sub Command1_Click()
Picture1.ScaleWidth = 109
tenth = 10
For i = 1 To 11
Call UpdateStatus(tenth)
x = Timer
While Timer < x + 0.75
DoEvents
Wend
Next
End Sub
Private Sub Form_Load()
Picture1.FontBold = True
Picture1.AutoRedraw = True
Picture1.BackColor = vbWhite
Picture1.DrawMode = 10
Picture1.FillStyle = 0
Picture1.ForeColor = vbBlue
End Sub
- F5 运行, 点击 Command1就可以看到效果.
