今天下了个可以调用dll的扩展命令:_call.exe 下下来后改成了func.exe,然后从网上搜了段可以使指定颜色透明的代码（VB）的。

Public Declare Function SetLayeredWindowAttributes Lib _ "user32" (ByVal hnd As Long, ByVal clval As Long, _ ByVal alph As Byte, ByVal flago As Long) As Long Public Declare Function GetWindowLong Lib "user32" Alias _ "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long Public Declare Function SetWindowLong Lib "user32" Alias _ "SetWindowLongA" (ByVal hnd As Long, ByVal nIndex As Long, _ ByVal dwNewLong As Long) As Long Public Const LWA_ALPHA = &H2& Public Const LWA_COLORKEY = &H1& Public Const GWL_EXSTYLE = (-20) Public Const WS_EX_LAYERED = &H80000 Public Const WS_EX_TRANSPARENT = &H20& 部分透明窗体（窗体的一部分颜色透明）： Dim lOldStyle As Long lOldStyle = GetWindowLong(Me.hwnd, GWL_EXSTYLE) SetWindowLong Me.hwnd, GWL_EXSTYLE, lOldStyle Or WS_EX_LAYERED SetLayeredWindowAttributes Me.hwnd, &HFFFFFF, 255, LWA_COLORKEY

照着改成批处理的代码：

@echo off set GWL_EXSTYLE=-20 ext\func user32.dll GetForegroundWindow ::返回当前窗口句柄 set "hnd=%errorlevel%" ext\func user32.dll GetWindowLongA -d %hnd% -d %GWL_EXSTYLE% set "lOldStyle=%errorlevel%" ext\func user32.dll SetWindowLongA -d %hnd% -d %GWL_EXSTYLE% -d %lOldStyle% ext\func user32.dll SetLayeredWindowAttributes -d %hnd% -d 0 -d 255 -d 1 pause>nul

不知道为啥不行咧(好像那个or运算实现不了？是这个原因么？) 请高手指教。。。。
