VC如何设置对话框的背景为透明效果?

请大家帮下忙
我是问VC对话框的

Answer 1

//在OnInitDialog里进行初始化，添加如下代码
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(),0,128,2);
FreeLibrary(hInst);
}

经典（引用他人的）

Answer 2

为对话框设置背景颜色、控件颜色
既然mfc对话框不好开发，

Answer 3

HBRUSH CUiuiDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Change any attributes of the DC here
pDC->SetBkMode(TRANSPARENT);

// TODO: Return a different brush if the default is not desired
return (HBRUSH)GetStockObject(NULL_BRUSH);

}
