    Deployment of Demo Application

    The free live version, sans any customisations, will be split FE/BE. I will do my best, hopefully with @isladogs help, to lock down the demo and live password-encrypted accde FE. Meantime, for the demo version I just deleted all the BE table links, imported sanitised/compressed BE tables to...

    Solved "Encrypted-Split-No-Strings-DB" - Security Challenge Solved

    Okay thanks. Me thinks MSRC rejected my submission because MS' priority focuses on the online M365 product. I pointed out all the loose ends I found in compiled accde's which need to be tied up. Perhaps approaching the MS Access Team would be more effective. I will email you, thanks!

    @isladogs , Ironically, I am planning to distribute a free templated version of my pawnshop management app to select pawnbrokers who will pay for customizations and I need to really lockdown the FE and BE from intrusion. Can you further harden your demo challenge? See my related post...

    Deployment of Demo Application

    Thanks for the advice. For the demo I am limiting the number of customers, contracts, transactions that can be added. I was thinking that by combining the frontend objects with backend tables into one password-encrypted accde that it will only work for one seat. If a prospect likes the demo and...

    Deployment of Demo Application

    Hi Pat, the dark theme is popular and the color-coded text has meaning, e.g. green money, red warning, blinking red requires immediate action, yellow and large fonts important, etc.... I have 65 sites using this app's theme and they say the black background is a lot easier on their eyes than...

    Deployment of Demo Application

    I am planing to distribute via CD-ROM a demo version of my Access 2010 pawnshop management app to select pawnbrokers in a geographic area. I was thinking about combining the frontend objects and backend tables into a compiled password-encrypted accde, and using 2010's packaging wizard to sign...

    Perhaps it could also be the infamous version 1803 / Win10 MS bug, or his D path is not a trusted location?

    Hi Dave, I noticed you tried opening them from your D drive, maybe it needs to be on C? Also, are you opening it in exclusive or shared mode from the cmd shell command line?

    Portable database for storing images or any binary file

    AFAIK, the only portable database that I know of that doesn't require user installation is a devices' native filesystem.

    Portable database for storing images or any binary file

    Hi @Pat Hartman , Hope you are well. Its been a while since we last connected. As this thread stands, unless the OP provides more clarity, I think the point of this thread is moot because his initial statement is controversial. I bid 3NT on this thread :) @The_Doc_Man Thanks for the heads up...

    Portable database for storing images or any binary file

    It's possible to store all those as BLOB's within a free db server with no limits like PostgreSQL but it requires installing PostgreSQL software in order to access those objects. NOTE: When I include a weblink in my posts and press "Save", an error message says it looks like you are posting...

    Portable database for storing images or any binary file

    Why not store the images externally in OS folder(s) and the path for each image in an Access table? This way your images can easily be ported and you don't have to worry about db size limits and performance degradation.

    Solved "Encrypted-Split-No-Strings-DB" - Security Challenge Solved

    Hi Doc, I guess Colin needs to go back to the drawing board and improve the hardening of his frontend demo because as you are well aware that while the frontend has an open link to backend tables, if you enable the various FE UI features, options, and view string values with the vba object...

    Solved "Encrypted-Split-No-Strings-DB" - Security Challenge Solved

    The multiple security-holes in compiled accde front ends were the low hanging fruit I was able to exploit to unlock enough options which made it possible for me to use, e.g. the vba object browser to view values like RC4_Key, your Cipher key, strPassword, the password to your encrypted backend...

    Solved "Encrypted-Split-No-Strings-DB" - Security Challenge Solved

    I am not an experienced Access/VBA developer and after not too much effort I was able to break into the accde frontend of the "encrypted-split-no-strings-demo-database" security challenge, alter settings, and view enough things which made it possible for me to reach RC4 encrypted data in the...
