Hi!
I have meke a simple programs on c++ with visual studio.
The program have a dll where I put my name e my personal details.
I realize that anybody can take my executable file and with a simpli
resource editor can be edit, delete or replace my details with other data.
How can block this possibility? How can prevent the resource editing? It's
possible?
Thanks.

You can encrypt the personal details and put the encrypted string into
executable. You program then decrypt the encrypted information when
need.

Calculate a checksum of the program that is checked in all/most
functions in the DLL and if the checksum does not match then crash the
program.
Seriously though, why would you worry about that? I find it less than
likely that someone would actually try to steal your work and pass it
of as their own (I assume here that by personal information you mean
copyright information, if it's something else it should not be in the
file to start with).

Yes, this is my foible. But shortly I would like to put my programs on
internet, how free programs, and my only request is that my programs remain
unchanged.
Thank for your help!

Don't waste your time "protecting " against this. Focus on the fact that
the honest users will honor your request to not change things. The
honest users are the majority.
The *only* two ways to keep someone in the non-honest minority from
changing your program without asking are:
1) Don't release your program or
2) Make your program completely undesirable This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

Ok, now that I've got my disk imager program working, I'd like to attach a
"self-extractor" to the front end of the image file and make it a
self-extracting disk image executable file. The idea being that the user
would double-click on the file and the disk would be created. I would like
to be able to "create" the self-extracting disk image from my program. Any
guidance on how to go about doing this?
thanks.

I need to add binary data to C# executable and then read it back
during execution or from another application.
In Delphi for Win32 I used the following:
- created binary Win32 resource with needed data;
- linked this resource with executable through {$RESOURCE <filename>}
directive;
- during execution I used TResourceStream to read binary data;
- from another application I used

Hi,
I was wondering if we could parse or do something in the executable(
whose source language was C). How can I use some scripting language
like perl/python to find out the information about the executable ? Is
it possible ?
Also, how does the compiler add inling to the program ? I know that
whenever it sees"inline" in front of the procedure name, it inlines it.
But if we give the -finline options, it inline all the procedures ? How

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
