怎样实现透明窗口？类似360那个健康精灵那样的程序？
想做类似于360那个健康精灵的程序，该怎样实现窗口的透明？ （bcb开发）
[解决办法]

SetWindowPos(Handle,HWND_TOPMOST,0,0,Screen-> Width,Screen-> Height,SWP_SHOWWINDOW); 

SetWindowLong(Handle,   GWL_EXSTYLE,   GetWindowLong(Handle,   GWL_EXSTYLE)   
[解决办法]
 
WS_EX_TRANSPARENT   
[解决办法]
   //忽略一切消息（WM_PAINT除外） 
WS_EX_LAYERED);   //层风格，有他才能支持半透明 
SetLayeredWindowAttributes(Handle,   Color,   100,   LWA_ALPHA   
[解决办法]
   LWA_COLORKEY);   

[解决办法]
有难度啊
[解决办法]
没试验图片，这样行不

C/C++ code
void __fastcall TForm1::FormCreate(TObject *Sender)
{
BorderStyle = bsNone;
Brush->Style = bsClear;
}

楼上的大牛能不能帮忙把帖子里的delphi代码转为CB的代码？
小弟想转为CB代码自己调试一下，可是不懂delphi，希望大牛帮忙。
[解决办法]
用第一种方法不行吗

void __fastcall TForm1::FormCreate(TObject *Sender)
{
  BorderStyle = bsNone;
  Brush->Style = bsClear;
}

[解决办法]
第二种改的cb
