VB 任务栏透明
代码：
Option Explicit
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function SetLayeredWindowAttributes Lib "user32" (ByVal hwnd As Long, ByVal crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As Long
Const WS_EX_LAYERED = &H80000
Const GWL_EXSTYLE = (-20)
Const LWA_ALPHA = &H2
Private Sub Form_Load()
dim bHwnd as Long
bHwnd = FindWindow("Shell_TrayWnd", vbNullString)
SetWindowLong bHwnd, GWL_EXSTYLE, GetWindowLong(bHwnd, GWL_EXSTYLE) Or WS_EX_LAYERED
SetLayeredWindowAttributes bHwnd, 0, 128, LWA_ALPHA
'上面的128改成不透明度(0和255之间)
End Sub
取消透明的方法是
Private Sub Command1_Click()
Dim newhwnd
Dim bHwnd As Long
bHwnd = FindWindow("Shell_TrayWnd", vbNullString)
SetWindowLong bHwnd, GWL_EXSTYLE, GetWindowLong _
(bHwnd,GWL_EXSTYLE & WS_EX_LAYERED)
END SUB
