How do I get a list of Access tables and their row counts?

For any one table, you can get the number of rows with the following query: 
 
SELECT COUNT(*) FROM <tablename>
 
To iterate through each table, though, you have to do a little more monkeying around (thanks to Dirk Goldar for the script): 
 
SELECT 
    Table_Name = Name, 
    Row_Count = DCount("*",[MSysObjects].[Name]) 
FROM 
    MSysObjects 
WHERE 
    (Left([Name],1)<>"~") 
    AND (Left([Name],4) <> "MSys") 
    AND ([Type] In (1, 4, 6)) 
ORDER BY 
    Name
 
If you want to do this in ASP, you could call this query directly. Another approach would be to use ADOX to iterate through the list of tables, and execute SELECT COUNT(*) against each one: 
 
<%  
    dbname = "databasename"  
 
    ConnStr = "Provider=Microsoft.Jet.OLEDB.4.0;data source="  
    ConnStr = ConnStr & "<path>\" & dbname & ".mdb"  
 
    Set adox = CreateObject("ADOX.Catalog")  
    Set conn = CreateObject("ADODB.Connection")  
    conn.open ConnStr  
    adox.activeConnection = conn 
 
    for each table in adox.tables  
        if table.type="TABLE" then  
            response.write table.name & " - "  
            set rs = conn.execute("SELECT COUNT(*) FROM " & table.name) 
            response.write rs(0) & "<p>" 
        end if 
    next  
 
    conn.close 
    set conn = nothing  
    set adox = nothing  
%>
