Open a website with default browser

[tomtiefi]

Hello,

I use WinCC OA 3.11.
How can I open a website (webcam) with the button Clicked event?
I want to start the default browser.
Or what is the best practice?

Hello Thomas,

the WebView Ewo allows you to display HTML content within your panels (not sure though if it had already been implemented in 3.11 or your specific webcam will be able to be displayed correctly)

or a simple system call (this opens the default browser):

Code: Select all

int rueck;
rueck=system("start /MIN http://www.etm.at"); 
  return 0;

The correct way is:
use the std_help() function from our std.ctl library.
Doing so, you will do it in a platform neutral way and your script will work on all supported platforms (even new ones in the future, e.g. Android)
E.g.: std_help("http://my.web.site");

Thanks for your answers,

I tried the start command and the help function, both are okay for me.
