Re: Open a v17 data file when Structure is unknown

re: 4D thought through all of this with the v11 data file format. They wanted to make it super hard to do exactly what you are trying to do — take a data file that you have no structure file for and then reverse engineer out the structure so that you can extract the data. Yup, used that

Re: Open a v17 data file when Structure is unknown

Jorg, a couple of things to watch for: - hidden field(s) - I do not believe these will show up to be exported. - blobs - they will export, but without knowing what is in them... -- encrypted blobs - again they will export, but the data will be useless; and I do not believe there is any way to

Re: Open a v17 data file when Structure is unknown

Hi JPR, Thanks for all the additional input it helped a fair bit. I try to be careful not to loose anything in regards of structures (DBs), passwords and pass phrases. ;-) Cheers Jörg ** 4D Internet Users Group (4D iNUG)

Re: Open a v17 data file when Structure is unknown

Jorg, Sorry, I missed the bit about the compiled structure. Sounds like a difficult situation. But if you have access to user mode exporting all the data is as good a solution as any, really. It's slow doing the export but you only have to do it once. On Sat, Jun 8, 2019 at 6:31 PM Jörg Knebel

Re: Open a v17 data file when Structure is unknown

Hi Kirk, As mentioned in an other post the client has a compiled structure, but the guy the business was bought of refuses to hand over the source code. The funny thing is the business is based on and depends on that application, meaning no application/data no business. It is possible to go to

Re: Open a v17 data file when Structure is unknown

Jorg, Well, one man's 'data rescue' is another man's 'data breach'. Frankly it sounds a little hinky that a client would have a lone datafile and no clue about where the structure file is or who created it. But I have run bars and restaurants in my past and am suspicious of stories like that. In

Re: Open a v17 data file when Structure is unknown

the data analyser written by JPR https://kb.4d.com/assetid=77253 had code that could essentially be used to retrieve structure information out of a data file. (but it's a compiled database) I used it to write this tool to edit the UUID of a structure and data file (was WEDD resource in

Re: Open a v17 data file when Structure is unknown

Hi Chuck & Tim, Thanks for all the input. I’m aware that I’m talking about some “hacking” a data file with a generic structure to retrieve the content. And I know about all the UUID used since v11 but I’m wondering where all the UUIDs are stored in the data file. As of now this all turned into

Re: Open a v17 data file when Structure is unknown

Perhaps if you can prove ownership of the data 4D can assist. I know that even when you buy an application you do not own the app just a license to use but you do own the data What happened to the structure. Is there a compiled version somewhere Regards Chuck On Thu, Jun 6, 2019 at 3:20 PM Tim
