IDiaSession::getEnumTables

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);
}
