need help with ColumnHistory()

[sooli]

Trying to make a "white board" type feature in my database so we can share information between shifts.

I like the ColumnHistory() feature, but it seems to keep adding to the history even if you don't type anything in.

I think it has something to do with the Nz() part of the standard code, but am unsure exactly. Everytime the form is opened, it creates a new line and I don't want it to create a line unless the post button is hit...

History Text box code is:

=ColumnHistory([RecordSource],"Comments","[ID]=" & nz([ID],0))
 

form load code is:

Private Sub Form_Load()
On Error GoTo Form_Load_Err
 
    If (Not IsNull(OpenArgs)) Then
        DoCmd.GoToRecord , "", acLast
    End If
    If (Not CurrentProject.IsTrusted) Then
        Exit Sub
    End If
    Comments.Value = " "
    txtComments.Visible = True
 
 
    TempVars.Add "NewData", Mid(Nz(OpenArgs), InStr(Nz(OpenArgs), "=") + 1)
    On Error Resume Next
    If (TempVars!NewData <> "") Then
        Title = TempVars!NewData
    End If
    TempVars.Remove "NewData"
 
 
Form_Load_Exit:
    Exit Sub
 
 

I thought the "TempVars.add..." might be the cause of this, but when i commented it out, it still happens...how can I make this only store/display data if the Post button is hit?

Also would like it to not say "Version: 6/19/05..." how do i make the word "version" disappear and only the date and time show up?


thanks for your help!

oh! seems

Comments.Value = " "
txtComments.Visible = True
 

was the culprit... so that is fixed..

[sooli]

is there a way to make it display newest to oldest? so the most recent comment is at the top?

[sooli]

i got it to at least load with the cursor at the end of the text, using

txtComments.setfocus
Me!txtComments.SelStart = Me!txtComments.SelLength
 

but I'd really like to have the data appear in reverse order...

It looks like the History is being appended to by a piece of code that hasn't been supplied. It's probably in the BeforeUpdate Event of the Form or off a button that saves off the History text. The question is whether or not when the History is saved, is it just appending to a Text field or is it creating a separate record for each piece of history.

• If it is appending the History, then to get it in reverse order, the History would need to be prepended instead.
• If there is a record for each piece of history, the ColumnHistory() function could be modified to allow you to supply the sort order... or just hardcoded in reverse order.

Having a peek at the ColumnHistory() function would probably answer this question.
