Open a password protected template

deeeiy057 — Fri, 02 Feb 2024 08:23:40 GMT

Hello everyone, i want to create an instance of a drawing from a locked template (a template that i have created and secured using a password) using VB.Net. the problem is when i use the "add" method, i can't specify the password since the is no such argument to pass, however when i use the "open" method, it opens the specified drawing directly without making an instance of it. Can you help me hout to solve this problem?

Passwords were never intended to be used to prevent someone from modifying a file (which I presume is why you passworded the template file). They were intended to prevent unauthorized access to the file's contents, and I don't think they ever considered passworded template files in their design.

Would it not be possible to secure the template file at the OS-level using permissions?

Hi, thanks for your replay.

The reason why i can't secure my template using the OS-level permissions is because my app is to be instaled on a local machine and all the support files are copied in the instalation folder.

The password protection has been removed:

How about storing them in. Zip files, or as embedded resources? When your application is loaded at startup you can simply extract the templates from the zip or from your resources and write them into the template folder, overwriting any unauthorized changes that were made to them.

Hi, thanks for your replay, i think its a good idea to store them in a zip file and to extract them when the application starts, will give it a try! Thanks a lot
