   Hello.
   
   I've been trying to read some data from the DBC files using a simple memory reader. I'm just not sure why I can't get results. Some files are working fine like Languages.dbc, but when using a file like GameObjectDisplayInfo.dbc I get weird data back. I might be doing it wrong, which I think is the case. I hope BBCode workes.
   
   This is what I'm using.
   
   
/*
1 Signature String (4-bytes) string, always 'WDBC'
2 Records Integer (4-bytes) number of records in the file
3 Fields Integer (4-bytes) number of fields per record
4 Record Size Integer (4-bytes) Fields*FieldSize (FieldSize is usually 4, but not always)
5 String Block Size Integer (4-bytes) Size of the string block
*/
int nPtr = Memory.ReadInteger(Convert.ToInt32("0xC01AF4", 16));
int nRecords = Memory.ReadInteger(Convert.ToInt32("0xC01AF4", 16) + 4);
int nRows = Memory.ReadInteger(Convert.ToInt32("0xC01AF4", 16) + 8);
int nLastEntry = Memory.ReadInteger(Convert.ToInt32("0xC01AF4", 16) + 12); // Last entry?

// 1625 records for GameObjectDisplayInfo.dbc
Console.WriteLine("nRecords: " + nRecords);

// We foreach through nRecords using "i" as our "id" entry.
for (int i = 0; i < nRecords; i++)
{
// * 4 would the first row? I'm unable to find an actual row count.
int nRow = Memory.ReadInteger(nRows + i * 4);

// 48 is record size as per:
// http://www.hackwow.com/wiki/GameObjectDisplayInfo.dbc
int nField = Memory.ReadInteger(nRow + 48 * 4);

Console.WriteLine("Field: " + Memory.ReadString(nField, 128));
}

   
   Outputs as follow:
   
   

   
   nRecords: 1625
   Field:
   Field:
   Field: Scorpid Worker
   Field: 0
   Field: LumberPile
   Field:
   Field: Mottled Boar
   Field:
   Field:
   ..
   

   
   
   What puzzles me is that when doing:
   
   
Memory.ReadInteger(Convert.ToInt32("0xC01AF4", 16) + 4);

   
   I get the record count of the file fine (1625 in case of GameObjectDisplayInfo.dbc), but acording to the header that's posted, doing +8 should give you number of fields per record? Reading +8 returns a pointer to somewhere in my case, can't quite figure it out.
   
   The address itself C01AF4 is pointing to the start of the file.
   
   
.text:0053A4B7 mov ecx, offset dword_C01AF4 <-
.text:0053A4BC call sub_53FB10

   
   Apreciate any tips.
