Any table or field added to the structure will have a unique ID (UUID) associated with it. Any data created with that structure is placed in the data file with the same UUID reference as the structure file used for opening the database. If a table or field is added to the structure in multiple copies they will have different UUIDs. Since the data is stored with the UUID of the structure, the data will only be accessible to the structure used for adding that data. Lets say in Structure #A a table named Table_A is added and it is automatically assigned a uuid of ABC123. Then, in Structure #B a table named Table_A is also added and it is automatically assigned a uuid of XYZ987. Data added to Table_A from Structure #A will only be accessible to Strucutre #A as it will have a UUID of ABC123. If Structure #B attempts to load the data file from Structure #A the values associated with UUID ABC123 will not be visible as Structure #B is trying to use UUID XYZ987. In other words this data will be lost. In this situation, running a Recover By Record Headers in v12 will show that there are tables with an 'unidentified destination' in the data file. This type of situation should be avoided. = See also: http://livedoc.4d.com/4Dv16-R2/help/Command/en/page1125.html http://livedoc.4d.com/4Dv16-R2/help/Command/en/page1126.html -Tim ** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **
Re: Creating a Word document from 4D
I erroneously looked at the 4DWrite documentation when I intended to read the 4DWrite Pro docs. So my post below should have asked whether one can generate a Word doc from 4DWrite Pro. -Original Message- From: David Rose Sent: Thursday, March 30, 2017 9:25 AM To: 4d_tech@lists.4d.com Subject: Creating a Word document from 4D In a Windows-only 4D v15 db I need to generate Word documents. I haven't used 4DWrite in a while, but see in the documentation for WR SAVE DOCUMENT one can save a 4DWrite document as an rtf file. there is also this note: "Compatibility note: To retain compatibility with previous versions, the DOC8 (Word 8 Document) type is also supported." Is anyone saving 4DWrite docs as Word docs, and if so, are there any issues? Is the formatting in 4DWrite docs faithfully reproduced in the resulting Word docs? Does the above compatibility note suggest that support for Word may not be found in future 4DWrite versions? Are there other ways to generate a Word doc from 4D? The documents I need to generate will be parallel to a 4D "Detail form for printing" containing multiple records on each page, and flowing to multiple pages when there are more records than can fit on one page.
