I am working on ADO database programmin in vc++ (VC6),i have a problem to get the all table name from MS access database file (*.mdb file) using vc++ with ADO.
e.g. if database table contains table1, table2, and table3 tables then i need to display all table name.
I tried the following code i didn't get table name.

C#

   _ConnectionPtr pConnection = NULL;
   _RecordsetPtr pRstSchema = NULL;

   _bstr_t strCnn("Driver={Microsoft Access Driver (*.mdb)};"
           "Dbq=c:\\dbaccess.mdb;Uid=;Pwd=;");

      pConnection.CreateInstance(__uuidof(Connection));
      pConnection->Open (strCnn, "", "", adConnectUnspecified);

      pRstSchema = pConnection->OpenSchema(adSchemaTables);

    while ( !(pRstSchema->EndOfFile) ) {
         _bstr_t table_name = pRstSchema->Fields->GetItem("TABLE_NAME")->Value;

         printf("Table Name: %s\n",(LPCSTR) table_name);
}

But by using above code it is displaying like this Mysysobj instead of table1,table2... etc.

So please tell me where i am doing mistake or give some other methods to do this.

Add MoveNext() as was proposed below.

Solution 1

Insert this at the end of the while loop:

C++

pRstSchema->MoveNext();

Otherwise, you have an endless loop showing only the first table name.

The MSys* tables are MS Access internal tables. If you want to exclude them from being shown, just check for names beginning with 'MSys'.
