VC++ & ODBC, MS Acces database w/ multiple tables

Hello,
Regarding VC++ based tools w/ ODBC Access .mdb's.
Recently discovered that, upon executing VC++ New Project Wizard, & pointing it to an .mdb source, that that same .mdb source can have multiple tables & the generated code supports it.
But I can only realize that from a read-only perspective, having problems if I try to write to those tables.
I rely on standard code like:
m_pSet->Edit();
Followed by make some update to the .mdb contents, then...
m_pSet->Update();
And if the .mdb source has just 1 table that works fine.
But if the .mdb contains multiple tables, upon execution the error is declared: "Recordset is read-only".
While the code above still compiles when multiple tables are involved, it's apparently insufficient in that it's not making EACH of the .mdb source's multiple tables edit -able.
Presumably, in this case "m_pSet->Edit();" needs to specify the specific tables involved.
Code suggestions appreciated.
