vc++6.0基于对话框如何将usb视频全屏，我是菜鸟求具体代码步骤？！

Answer 1

int frameWidth = GetSystemMetrics(SM_CXFRAME);
int frameHeight = GetSystemMetrics(SM_CYFRAME);
int captionHeight = GetSystemMetrics(SM_CYCAPTION);
int screenWidth = GetSystemMetrics(SM_CXSCREEN);
int screenHeight = GetSystemMetrics(SM_CYSCREEN);
CRect rect;
GetClientRect(&rect);
rect.left = rect.left - frameWidth;
rect.top = rect.top - frameHeight - captionHeight ;
rect.bottom = rect.top + screenHeight + 2 * frameHeight + captionHeight;
rect.right = rect.left + screenWidth + 2 * frameWidth;
ShowWindow(SW_HIDE);
SetWindowPos(HWND_TOPMOST, rect.left, rect.top, rect.Width(), rect.Height(), SWP_SHOWWINDOW);
