Not sure if this question has been asked already. I searched and so far have found nothing. I built an application in Access 2007 on a Windows 7 machine. I used VBA for all the coding. I am now running it in Access 2010 on a Windows XP machine. I have a line of code that reads: SendKeys "^{ENTER}". It allows me to open a macro I select from a listbox. It works perfectly in 2007 but not 2010. I am wondering if this is a computer and OS issue or an Access version issue. Any ideas?
