怎么样让VB窗口变透明？

'函数SetLayeredWindowAttributes ' 使用这个函数，可以轻松的实现半透明窗体。按照微软的要求，透明窗体窗体在创建时应使用WS_EX_LAYERED参数（用CreateWindowEx），或者在创建后设置该参数（用SetWindowLong），我选用后者。全部函数、常量声明如下： 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 ' 其中hwnd是透明窗体的句柄，crKey为颜色值，bAlpha是透明度，取值范围是[0,255]，dwFlags是透明方式，可以取两个值：当取值为LWA_ALPHA时，crKey参数无效，bAlpha参数有效；当取值为LWA_COLORKEY时，bAlpha参数有效而窗体中的所有颜色为crKey的地方将变为透明－－这个功能很有用：我们不必再为建立不规则形状的窗体而调用一大堆区域分析、创建、合并函数了，只需指定透明处的颜色值即可，哈哈哈哈！请看具体代码。 Private Const WS_EX_LAYERED = &H80000 Private Const GWL_EXSTYLE = (-20) Private Const LWA_ALPHA = &H2 Private Const LWA_COLORKEY = &H1 Private Sub Command1_Click() Unload Me End Sub Private Sub Form_Load() Dim rtn As Long rtn = GetWindowLong(hwnd, GWL_EXSTYLE) rtn = rtn Or WS_EX_LAYERED SetWindowLong hwnd, GWL_EXSTYLE, rtn SetLayeredWindowAttributes hwnd, 0, 150, LWA_ALPHA End Sub

D 这个就是idiom（惯用语），"no such thing as"你就记住就好了，我也解释不来我的母语是英文啊，没错的

not such a ___ thing 只能在有其它修饰词或指很明确的事情/物体时用，如

That's not such a good painting

那幅画不怎么样嘛。

意思不一样了，这里的意思是"没这回事儿“/“没这个概念。“只能用"no such thing as"

忘讲了，句子的意思就是：

土地是属于城市的，没有私有土地权利这回事儿。

private sector

私人部门

private sector[英][ˈpraivit ˈsektə][美][ˈpraɪvɪt ˈsɛktɚ]

私营成分，私营部门;

例句:

1

How's life in the private sector

私营生意做得怎么样了
