Don't work Google Calendar in WebBrowser (IE9 release)


  • Google Calendar working in IE9 very good, but in WebBrowser Google Calendar slowly working only IE7 mode.

    If I set FEATURE_BROWSER_EMULATION for WebBrowser App to mode IE8 or IE9 (8000, 8888, 9000, 9888, or 9999) - Google Calendar not react at any CLICK (Create Events). I try set step-bystep all Internet Feature Controls for WebBrowser ( ) - not any results


    P.S. My english - is very bad. I'm sorry.

  • Hi Alexander,

    I don't know if it helps to improve the performance, but it is worth to try.  Use FEATURE_GPU_RENDERING  to enable GPU rendering feature of IE9 based webbrowser.

  • Thanks. But it is no solution. I already wrote that I tried all ways of (including FEATURE_GPU_RENDERING) - without result. Perhaps a workable is some combination of parameters in the registry. I can not figure out what's the problem.

  • I analize all reg events:

    and set 0 or 1 - any results.

    And I tried to put 1 and 0 for the WB and IE9. WB is not repaired, and IE is not broken. Trouble. Help, I really need to solve this problem with Google Calendar

    PS. If I rename exe-application with WebBrowser to iexplore.exe - calendar Google very good work.  I'm shocked

  • Hi,

    Check that you don't have * in your IE Compatibility View lists or that you have not set "Show all sites in Compatibility View" and

    (Important) do a Windows Update so that your IE8 site compatibility lists are updated from MS. (IE9 does automatic updates of these lists)


    Google asked MS a while back to remove all their sites from the MS compatibility lists, as they converted all (well... they have missed a few we are finding) of their sites to the system Doctype.

    You may like to troll the google support forums or

  • Thanks for the tips, although Google has nothing to do with it. Google Calendar's features work in IE9, but not working in WebBrowser (based on the same IE9) - here is a problem. In any case, further support is required, I found a suitable solution.
