Hi,

I have used the following code to get table info from my database.
My database contains only one table.
I don't know why the index value must be set to 4 in order to get the name of the table.

Can anyone tell me what is the use of the value index?
If my database contain only one table, why I can't get the name of the table by setting the value of index equal to 0.

--------------------------------------------------------------------------
CDaoTableDefInfo TableInfo;
int index=0;
BOOL lp= TRUE;
while (lp)
{
m_pDBList->GetTableDefInfo(index,TableInfo,AFX_DAO_ALL_INFO);
if (!(TableInfo.m_lAttributes & dbSystemObject)&& !(TableInfo.m_lAttributes & dbHiddenObject))
{
break;
}
  index++;
}

--------------------------------------------------------------------------


Thanks!!!

Hi

Index is just a look up number of the perticular tabledef collection in the database it doesn't have to do any thing with the number of tables present in the database.

inpras is probably correct.

There are also hidden and system tables, correct? I am only guessing, but perhaps they use index values that are less than 4.

I forgot to mention something. Did you try doing something like setting a breakpoint on the if statement after the GetTableDefInfo call to see what the results were for indexes 0 to 4?

I am not sure about this but...
It may be so that 5 tables were created and the first 4 were deleted.

Can you try creating this table and then get the table info?

These are the first 4 system tables:

Index   Table name
 0        MSysACEs
 1        MySysObjects
 2        MySysQueries
 3        MySysRelationships

That is why your table index is 4.

If you want to get only the user tables, you can try something like this:

CDaoTableDefInfo tdiTableInfo;
long lTableCount = m_pDBList->GetTableDefCount();

for(int i = 0; i < lTableCount; i++)
{
   m_pDBList->GetTableDefInfo(i, tdiTableInfo, AFX_DAO_ALL_INFO);

   if(tdiTableInfo.m_lAttributes & dbSystemObject | tdiTableInfo.m_lAttributes & dbHiddenObject)
      continue;

// tdiTableInfo.m_strName contains the table name.
// Display it.
   AfxMessageBox(tdiTableInfo.m_strName);
}
