Hello Lingmay

It is possible you have not included a foundation read in your application.

Without this command an executable will exit straight away.

Make sure you you have a read command somewhere in your start up program even if it has no screens in it.

I always use the cancel command as my preferred methos of leaving Foxpro because if you use it in an executable it will quit but when you are running your exe from the command prompt it will merely put you back at the command prompt (which is usually whats required)

Good Luck

Mark
