Protecting Code
Is there any utilities out there that will obfuscate the vba code?
What is the difference with com addin compared to a dll addin? Which one of those can call a secondary addin? Is there any limitations of moving the VBA code over to a addin? Has anyone had exerience with Protection Plus? I am planning on using many of these methods if they are feasible and allowable by excel. |

Protecting Code
just starting with vba myself, but vba for dummies says
that the way to do that is by turning the code into an addin which makes the code invisible to the user. The book tells how to do this. further, the book says that passwords are crackable - therefore offer little protection. -----Original Message----- Is there any utilities out there that will obfuscate the vba code?

Protecting Code
No, addins don't make the code invisible, it makes the workbook invisible.
You can password protect the code, but that is not very secure. Most secure way is to use a compiled process, like a dll. -- HTH RP (remove nothere from the email address if mailing direct) "Paul" wrote in message ... just starting with vba myself, but vba for dummies says that the way to do that is by turning the code into an addin which makes the code invisible to the user.

Protecting Code
I understand that the password can be cracked easily. What Im looking to do is make it more difficult. I have heard about obfuscating code, and , putting majority of it in a com or dll. What Im looking for is any suggestions and answers directly to the questions. #1) Which is the perferable place to move code into a DLL or a COM addin? #2) Can either of those call functions and procedures in another COM or DLL file? (Reason is I am considering using Protection Plus ) for trialware and registration. I would like to place it into the DLL) 3) Limitations of moving code to DLL or COM? (because I would like majority of the code moved ove, I need to no what limitations are before I do this. And how different is VB from VBA) 4) Has anyone used Protection Plus by softkey. It is a Protection I hope to use as part of the overall scheme. 5) does anyone know of any Obfuscating software that will make code difficult for a person to decipher. I need this for VB and VBA. |
