If same html file open in  Internet explorer or chrome, (Web-page) it is opening as expected, but same html file when call in Labview using

"active-X"  web browser, Web-page properties and design are changing.

I have tried all options related to active-x web browser properties

Hi P Vidya sankar,


From the screenshots it looks like the browser that the version of Internet Explorer loaded by the IWebBrowser2 control does not support the method addEventListener or the method getElementsByClassName.


Using the tool we can see that addEventListener and getElementsByClassName are supported in Internet Explorer 9 or greater.


The third party blog Web Browser Control & Specifying the IE Version describes ways to configure a newer version of Internet Explorer when using the IWebBrowser2 control. One approach it describes is adding the following tag to the head of your html document:



<meta http-equiv="X-UA-Compatible" content="IE=edge" />



Which looks like the following in a full html document (from the third party blog):



<!DOCTYPE html> 
    <meta http-equiv="X-UA-Compatible" content="IE=edge" /> 
    ... other headers
    ... content



With the header added you should also verify that you have a recent version of Internet Explorer available on your system. The third party blog goes into more details.
