IDiaSession::getEnumTables
Retrieves an enumerator for all tables contained in the symbol store.
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);
}
