I call Google map through JavaScript and open it directly in the browser, which can be opened normally. Call Google maps through the WebBrowser in the C + + program, which can be opened normally before(have Prompt for changing browser: ”The browser you are using is not supported by the Google Maps JavaScript API. Designer changing your browser.” But the map can be displayed normally); However, it has not been opened normally since last week (only the prompt to change the browser, but the map is not displayed). Why? Or other possible reasons?
