I have a program that has been running fine for years (VisualStudio 2015, Framework 4.6.1). As part of the program, I have a WebBrowser that can run a PHP page that draws a Google Map at a specific Map type / Longitude / Latitude / Zoom. Unfortunatly, everything when to a halt in February 2022, it just started showing java script errors instead of displaying the map.
For example, to display a map of Central Park, NY, my C# code looks like:
This would call my PHP script with the URL "http://MySite.com/MyMap.php?v=N&x=-73.9665&y=40.7812&z=14". Here is what my PHP page looks like:
Instead of getting my Google map as before, I now only get the popup. No changes were made to my program, so Google must have changed a script within the map:
If I call my PHP script with any browser, it displays my Google Map properly, except for IE 11 where I get a blank screen with the following error on the Console:
I know for a fact that the WebBrowser uses Internet Explorer internally, which support stops in August 2022. Somehow, it looks like Google decided to pull the plug a few months before that deadline.
What will happen with the WebBrowser after that, will it become unusable?
Is there an alternative way to call a PHP script that draws a Google map in a VisualStudio application?
Is there anyone that has a piece of code that still works to display a Google Map?
I know I can still use the following code without a PHP script, but the resulting map if clothered with unwanted popups, and I sill get a warning about Internet Explorer:
For example, to display a map of Central Park, NY, my C# code looks like:
C# program:
string Map = "N";
string Lon = "-73.9665";
string Lat = "40.7812";
string Zoom = "14";
string Url = string.Format("http://MySite.com/MyMap.php?v={0}&x={1}&y={2}&z={3}", Map, Lon, Lat, Zoom);
webBrowser1.Navigate(Url);This would call my PHP script with the URL "http://MySite.com/MyMap.php?v=N&x=-73.9665&y=40.7812&z=14". Here is what my PHP page looks like:
