Hi Steve
Here is some VBA code I use in MSAccess or MSExcel to handle extended text. You'll need to paste the code into a class module. Hope this helps.
Regards
Dallas
Code:
Option Compare Database
Option Explicit
'PURPOSE:
' This class creates extended text entries for any text code/text key on a remove and replace basis.
' Existing text for the code/key combination is removed and replaced with the text string provided.
' The class automatically breaks long text strings in memo type fields into suitable lengths for loading
' to MIMS.
'****************************** CLASS USAGE EXAMPLES ******************************************
'Public Sub UseExtTextClass_Set()
' Dim myText As clsExtText 'Create an instance of the class
' mims_go 'Log in to MIMS
' myText.TextType = "**" 'Two character Text Type Code
' myText.TextID = "000000023320020116ACCO" 'The Text Key
' myText.Text = "This is the text we want to load." 'The Text
' If Not myText.MIMS_SetText Then 'Load the text
' MsgBox "Error updating text" 'Handle any errors
' End If
' mims_stop 'Log out of MIMS
'End Sub
'Public Sub UseExtTextClass_Get()
' Dim myText As New clsExtText 'Create an instance of the class
' Dim someText As String
' mims_go 'Log in to MIMS
' myText.TextType = "DT" 'Two character Text Type Code
' myText.TextID = "0000100300068153BIPLEL01" 'The Text Key
' myText.MIMS_Fetch 'Get text from MIMS
' someText = myText.Text
' MsgBox someText
' mims_stop 'Log out of MIMS
'End Sub

Mark,
Congratulations on a pretty nifty piece of code!
Any chance you could post your fixed up version?

Mark,
I too am very interested in your corrected code. I am struggling with updating std text at the moment.
Many thanks in advance,
Carly
