在MFC中打开一个Halcon窗口（用图片控件作为载体）

打开Halcon窗口函数声明及定义

HTuple OpenWindow_(CWnd* pWnd)
{
	CRect rect;
	HTuple Row, Col, Width, Height;
	HTuple FatherWindow;
	HTuple WindowHandle;
	Row = Col = 0;
	pWnd->GetClientRect(rect);
	Width = rect.Width();
	Height = rect.Height();
	FatherWindow = (Hlong)(pWnd->m_hWnd);
	HalconCpp::SetWindowAttr("background_color", "gray");
	HalconCpp::OpenWindow(Row, Col, Width, Height, FatherWindow, "visible", "", &WindowHandle);
	return WindowHandle;
}

调用时

CWnd* pWnd;
HTuple hv_WindowHandle;
//获得图片控件
pWnd = GetDlgItem(IDC_SHOW_WND);
//获得了Halcon窗口句柄，就可以进行进一步操作了
hv_WindowHandle  = OpenWindow_(pWnd);
