No I was opening the required file in a form which was not set as top level. Then I was running my top level form. Under this circumstance the file did not get opened. So I changed the file opening form to top level as well and now it works.

>>I am trying to make a particular top level form (show as 2) the application front end and make the main VFP window invisible. This all works except that if I open files while the main VFP window is not visible and then load my top level form then those tables are apparently not available to my form. If I allow the main VFP window to be visible then all works ok. What am I missing or have not understood about top level forms?
