Notes for Callers

Obtain this interface by calling the QueryInterface method on an IDiaTable object. See the example for details.

Example

This example shows how to obtain the IDiaEnumSourceFiles interface from the list of tables in a DIA session object. For an example of accessing source file information, see the IDiaSourceFile interface.


IDiaEnumSourceFiles* GetEnumSourceFiles(IDiaSession *pSession)
{
    IDiaEnumSourceFiles * pUnknown    = NULL;
    REFIID                iid         = __uuidof(IDiaEnumSourceFiles);
    IDiaEnumTables*       pEnumTables = NULL;
    IDiaTable*            pTable      = NULL;
    ULONG                 celt        = 0;

    if (pSession->getEnumTables(&pEnumTables) != S_OK)
    {
        wprintf(L"ERROR - GetTable() getEnumTables\n");
        return NULL;
    }
    while (pEnumTables->Next(1, &pTable, &celt) == S_OK && celt == 1)
    {
        // There is only one table that matches the given iid
        HRESULT hr = pTable->QueryInterface(iid, (void**)&pUnknown);
        pTable->Release();
        if (hr == S_OK)
        {
            break;
        }
    }
    pEnumTables->Release();
    return pUnknown;
}
