Read only

[Greg Wills]

Thanks Rob for the reminder on the different ways to add data to 
stacks, I am beginning to master these!

Thanks Jacque for the info on zipping files. I did think that I would 
need to look into an installing program, but if zipping works then I 
will do this. Are there any solid reasons for using install programs, - 
other than guiding those who are not sure of where they should place 
programs that they install? Does anyone use a preferred installer?

Thanks Chip for the info on unlocking a file from within Rev. I will be 
trying the simplest method first (zipping) and work towards clever 
stuff as I get better at scripting etc.

Thank you all for your speedy responses.

cheers

Greg

Hi Greg,

Since you write "file", not "files", I assume the file is a
standalone Revolution application created by the Distribution
Builder.  That standalone will always be read only: neither Windows
nor Unix allow applications to modify themselves, so Revolution
standalones are not modifiable.

If your application makes changes that must persist beyond runtime,
those changes must be stored in a text file, external database, or
external stack.  The general approach is to create a "splash screen"
standalone that opens the "real" stack, which is seen as an external
file to the user.
