Format of fob files?

Business Central/NAV Developers Forum
1

Hi! I would like write some code that can create fob files. These fob files are usually imported and exported with the Object Designer, but I need some code that does the same. The fob files contain the object that is stored as a BLOB and some additional information, like Type, ID, Name and so on. So I need to know the stucture of the fob files. Any help would be appreciated. Michael

Anyone with a Phd in the noble art of Reverse Engineering here ? On a more serious note, I don’t think that the file format of a FOB is available for us poor mortal. However there might be some guys out there who’ve got enough time on their hand to hack into the file with an Hex editor and work out the structure. This should be child play for the guy(s?) at navsupport if as they claim, they managed to develope a licence generator. By the way, who’s the guy running navsupport ?

You can’t create a FOB file by your self. ;-( It must be done by C/SIDE. A solution is to generate a text file, import it in Navison and compile it. DONE! You will se the structure in the text file if you export a object as text. I have a done a function that generat Batch files from some parameters. And it works real nice.

Tarek, I don’t think that fob’s worth SoftIce Michael, Why do you need fob format create own. Object table have BLOB with all code info. I don’t know (not tested) about obj properties, but I think that BLOB should include properties. The biger problem is table specifications, but it stored in field table. If you using CFront there no problem at all. Export maybe is posible in C/AL, but import horrify me. Simply you are not able create field in C/AL. So,use CFront. BTW How do you think is it imposible that fob’s using the same algorythm like flf? About crypting I don’t know, but CRC looks like is.

For developing we have a list of modified objects. After developing has finished these objects should be exported automatically.

I already tried this with success. The BLOB actually seems to have all neccessary data for an object except for the information that is listed in the Object table. But I would like to use fob files, because they can be imported using the Import Worksheet, which is quite a useful feature.

I don’t think it uses crypting. Michael
