Ann, according to http://support.openview.hp.com/selfsolve/document/FID/DOCUMENTUM_QTP_00644, Windows 7 and Windows Server 2008 R2 do not support Windows API text recognition as XP did. Under QTP, getvisibletext only works in the optical character recognition (OCR) mode and its reliability is unreliable at best. Once you install QTP patches 00626 and 00644, text recognition under Tools > Options > Text Recognition will only allow the "Use only OCR" option to be selected. These patches do not limit text recognition but they accurately reflect your choices in QTP's tools. If these are not installed, you may want to do that and select the OCR only option. However, Getvisibletext should be your tool of last resort and it may not work as you need. Your best options are to use the object's test or native properties to retrieve the text content. Again, if the content is painted on the screen and is not reflected in the object's accessible property then the OCR option is your only choice unless you can extend QTP to make the information accessible.
