Retrieves an enumerator for all tables contained in the symbol store.

Syntax

HRESULT getEnumTables (   
   IDiaEnumTables** ppEnumTables  
);  

Parameters

ppEnumTables
[out] Returns an IDiaEnumTables object. Use this interface to enumerate the tables in the symbol store.

Return Value

If successful, returns S_OK; otherwise, returns an error code.

Example

This example presents a general function that uses the getEnumTables method to obtain a specific enumerator object. If the enumerator is found, the function returns a pointer that can be cast to the desired interface; otherwise, the function returns NULL.

IUnknown *GetTable(IDiaSession *pSession, REFIID iid)  
{  
    IUnknown *pUnknown = NULL;  
    if (pSession != NULL)  
    {  
        CComPtr<IDiaEnumTables> pEnumTables;  
        if (pSession->getEnumTables(&pEnumTables) == S_OK)  
        {  
             CComPtr<IDiaTable> pTable;  
             DWORD celt = 0;  
             while(pEnumTables->Next(1,&pTable,&celt) == S_OK &&  
                   celt == 1)  
             {  
                  if (pTable->QueryInterface(iid, (void **)pUnknown) == S_OK)  
                  {  
                       break;  
                  }  
                  pTable = NULL;  
             }  
        }  
    }  
    return(pUnknown);  
}
