Reading grfId from grf (PHP)

Dinges · Post by **Dinges** » 23 Aug 2005 11:26

As a new feature for my graphics site I would like to extract grfID's from grf files. Is there an exact location within the GRF file where I could find this ID? It is mainly for building a GRFid database, and to check if the GRF file uploaded is valid.

The location is not fixed in the file. You will have to parse it for the Action 8 which means understanding bits of http://wiki.ttdpatch.net/tiki-index.php ... phicsSpecs

I do not mean the NFO file, the encoded GRF file.

What do you think happens to the NFO file?

But why don't you force submitters to add the GRFID? Can't you make GRFID a required description field on the submit form?

Look at a GRF file with a binary editor. Compare with an NFO file. See how the numbers are the same, albeit with a few extra bytes...?

Should be quite easy with fread, fopen. Didn't take long to have it in TTShellExt (c++) ... (The conversation to unicode and OLE String is more work in TTShellExt)
