VB如何实现透明效果

1、新建EXE。

2、代码如图。下一页有文字版。

3、在通用里面输入这些。注意是 （通用）Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As LongPrivate Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As LongPrivate Declare Function SetLayeredWindowAttributes Lib "user32" (ByVal hwnd As Long, ByVal crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As LongPrivate Const WS_EX_LAYERED = &H80000Private Const GWL_EXSTYLE = (-20)Private Const LWA_ALPHA = &H2Private Const LWA_COLORKEY = &H1

4、在FORM里输这个。注意格式。Private Sub Form_Load() Me.BackColor = &HFF0101 Dim rtn As Long rtn = GetWindowLong(Me.hwnd, GWL_EXSTYLE) rtn = rtn Or WS_EX_LAYERED SetWindowLong Me.hwnd, GWL_EXSTYLE, rtn SetLayeredWindowAttributes Me.hwnd, &HFF0101, 0, LWA_COLORKEYEnd Sub

5、展示一下效果。

6、注意！控件不透明！
