Hi all,

I'm trying to use ADOX in C Builder 5.  I'm trying to add a table to a catalog using the following code:

TCOM_Catalog cat = CoCatalog::Create();
cat->Create(connectionString);
TCOM_Table table = CoTable::Create();
cat->Tables->Append(table);

When I hit that fourth line, I'm getting an error:

"Type mismatch in parameter 'Item' (wanted 'TVariantInParam', got 'TCOM_Table')"

Any suggestions?  This one's driving me mad!

Many thanks,

Russ

Try something like this:

OleVariant param = table;
cat->Tables->Append(param);
