dear all,

i'm now developing a program. which one is better, i built into many exe so there is no menubar or i buit into one exe useing menubar? considering if there is any changes in my program and i have to copy new exe file, i choose many exe methods.
this is my structure.
Main.exe ( main form )
-- Product.exe ( display in Grid, i issue do product.exe if selected)
-- Vendor.exe ( display in Grid, i issue do product.exe if selected )
-- PriceList.exe ( display in Grid, i issue do product.exe if selected )
-- Invoice.exe ( display in Grid, i issue do product.exe if selected )

But the problem is:
1. if i call invoice exe file from main exe file, after i issued thisform.release, the invoice exe file is released. but if i built the invoice project ( because there is changes )into exe (main exe file is still open ). error message come up with File Access Is Denied. because i think users only have to quit invoice file so they can do other work without quit from main exe file.
2. how to protect user so they can only run one main exe file. because it is impact on my temporary table file. if they accidently open two main exe file the temporary file is overwrite.

sorry if you dont understand what i say

thanks,


Ivan Agusta
