Editing ADO-recordset using code

I want to edit an ADO-recordset just by using code.

I have this book that suggest the following code :

m_recTitle.Edit
m_recTitles("Title") = "We all love VB6"
m_recTitles.update

When I use this in my code, I get the message, that the edit is not a valid method.
If I leave the edit out, it tells me my provider does not allow that action.
My provider is Microsoft Jet OLEDB 4.0

What is the right way to edit my recordset through code?

Thanks.

There is no ".Edit" method when using ADO Recordsets (at least in v2.0+).  

Remove the .Edit, and everything should work just fine.

ADO doesn't support edit method. It accpets a direct field assigning.
so if you have it like this it will work
m_rectitle("title) = "we love VB"
m_rectitles.update
it will work and updata a record

Oh, I meant to select that as "Answer", but anyway...

I thought I'd add one more comment:  When you begin to edit a recordset (By assigning a value to a field, as in your second line "m_recTitles("Title") = 'We all Love VB6'") that starts the "edit" session.  

With DAO, you had to issue an .Edit to begin the edit session.  With ADO, you just set a value to a field, and that begins it.  You can still .CancelUpdate to remove changes since a edit has begun, or .Update to save the changes.

REmember that if you leave the record (with a .movenext, perhaps) you will write the record even if you don't call the .update method explicitly.  This is different than DAO and causes a lot of problems for people switching Data Access providers.

You said:

"My provider is Microsoft Jet OLEDB 4.0" but are you sure you opened an ADO recordset?  Just one thing to check.

Thanks for the comments.

I allready tried it without the edit.

But I still get the message:
Runtime error '3251':
The operation requested by the application is not suported by the provider.

Any suggestions?

The default cursortype doesn't allow you to update the recordset.

Before you OPEN the recordset, add these lines:

m_rectitles.CursorType=adKeySet
m_rectitles.CursorLocation=adUseClient
m_rectitles.LockType=adLockOptimistic

Now you should be able to update your recordset!
