1楼的可以用。这是修改版的。
用法：
把下面的代码复制到任意模块中（新建也可），
然后在需要做透明处理的窗口中调用代码

SetTransparentWindow Me,QBColor(1), WinAlpha
'把窗口和FLASH控件的深蓝色（QBColor(10)）部分变成透明的

'//* ================ 窗体透明声明 ================ *//
Public Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" _
(ByVal hWnd As Long, ByVal nIndex As Long, ByVal dwNewLong 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 SetLayeredWindowAttributes Lib "user32" (ByVal hWnd As Long, _
ByVal crKey As Long, ByVal bAlpha As Long, ByVal dwFlags As Long) As Long

'FindWindowEx 用来获得FLASH控件的HANDLE。
Public Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As S
