If you use VBA code to populate a Memo field, then you are only limited by the max size of the DB ... not the ~65K  if you manually populate a memo field.

 Short answer is no.  You would need to split the field contents yourself and store in multiple fields.

 What is it your trying to accomplish?

Actually, the short answer is Yes.  From Help:

"Memo Lengthy text or combinations of text and numbers. Up to 65,535 characters. (If the Memo field is manipulated through DAO and only text and numbers [not binary data] will be stored in it, then the size of the Memo field is limited by the size of the database.) "

<<I want to store a big ammount of information, which is the description of a product >>

  And you need more then 64K of characters; that's one heck of a description!

Mx,

<<Actually, the short answer is Yes.  From Help:>>

  Technically yes, you can use AppendChunk() and GetChunk() to store more then 64k bytes of data, but then it's not exactly a "memo" field anymore.  You can't work with it directly in any real sense the way you would with other fields.  For example, try getting it onto a report.

  Of course splitting into multiple fields has some of the same issues, but then at least you can work with it through the UI to a certain extent.

  I took the question to mean in the context of dealing with regular fields through the UI.   What you suggesting is no different then sticking a file out on disk and reading that.   And actually, OLE linking to Word documents with the description might be a better idea.

Sorry to be disbelieving but are you really sure this is what you want?

I can't imagine a situation where anyone would want to store 20+  A4 pages of unformatted text as a visible field in an Access database.

Agreed, if you *truly* need this massive amount of text, then you may just want to store this in a Word Document and link/hyperlink to it from Access.

Awaiting your detailed explanation of this data...

@JDettman:

"Technically yes, you can use AppendChunk() and GetChunk()"

I'm not sure you need to use these just to write text >65K to a Memo field using VBA/DAO ...

@mx,

<<I'm not sure you need to use these just to write text >65K to a Memo field using VBA/DAO ...>>

  I don't know of any other way to do it other then that.
