>Hi all,

>In my code i use the following code to detect the version of IE
>
>loIE=CreateObject("InternetExplorer.Application")
>AGetFileVersion(laVersion, loIE.FullName)
>WAIT WINDOW STR(VAL(LEFT(laVersion[4],4)))
>
>I do this because we discovered that some functions in VFP 7 like XMLTOCURSOR and CURSORTOXML have problems when an older version of IE is installed.
>
>Now I have a problem with certain clients were we are sure that there is a IE6.0 installed but the above code gives a version 5.5 as returnvalue. If we look in the info of IE it says 6.0 but if we try to use any XML functions we get a CLASS DEFINITION NOT FOUND.
