实现窗口透明

只需在创建窗口函数中加入

SetWindowLong(this->GetSafeHwnd(),GWL_EXSTYLE,

　　　　GetWindowLong(this->GetSafeHwnd(),GWL_EXSTYLE)^0x80000)

　　HINSTANCE hInst = LoadLibrary("User32.DLL")

　　if(hInst)

　　{

　　　　typedef BOOL (WINAPI *MYFUNC)(HWND,COLORREF,BYTE,DWORD)

　　　　MYFUNC fun = NULL

　　　　//取得SetLayeredWindowAttributes函数指针

　　　　fun=(MYFUNC)GetProcAddress(hInst, "SetLayeredWindowAttributes")

　　　　if(fun)fun(this->GetSafeHwnd(),0,200,2)

　　　　FreeLibrary(hInst)

　　}-Just the realization of a transparent window in the creation of a window function to add SetWindowLong (this-> GetSafeHwnd (), GWL_EXSTYLE, GetWindowLong (this-> GetSafeHwnd (), GWL_EXSTYLE) ^ 0x80000) HINSTANCE hInst = LoadLibrary (　User32.DLL ) if (hInst ) (typedef BOOL (WINAPI* MYFUNC) (HWND, COLORREF, BYTE, DWORD) MYFUNC fun = NULL// function pointer SetLayeredWindowAttributes made fun = (MYFUNC) GetProcAddress (hInst,　SetLayeredWindowAttributes ) if (fun) fun (this-> GetSafeHwnd (), 0200,2) FreeLibrary (hInst))
