Hello,
I came across the following problem.
After compiling my app into executable I want to insert into it some data
(few bytes), probably at the end of the file.
How can I programmatically read those bytes from within the same code?
Your help appreciated,
Claire

You can use a resource file with a known marker in that you replace, and
can be read easily in your app using LoadResData() or append to the end
of the executable (data on the end won't effect the exe) and read it
using normal file I/O.

The resource method means you have an upper/fixed limit on size, but it
depends on the data itself as to whether that will be a problem or not.

I wonder though if anti virus programs would regard that as suspicious
behavior.

BTW are you trying to add a license key routine? I just give the
users a nine digit number. I create a file with that name and their
name encrypted in the file. I upload that to my website. Then my
program then downloads that file with the nine digit number from my
website.

Quite painless I hope. <smile>

That seems like a great approach. Do you use a hash for the encryption?

It could be possible to declare a string Const, and finding it's value and
change it.
Public Const MyCode As String = "asdfghjkl". Be aware it is stored as
Unicode.
