Automating my help text for a datasheet

following on from an earlier question ....

Private Sub SellingPrice_GotFocus()
Me.Parent.HelpTextForField = Me.SellingPrice.Tag
End Sub

Open in new window


This code is used in every field in my datasheet and displays "help" text that is held in the "tag".

I would like to automate a little further as follows;
1. Setup a new tblHelpUsers with two fields ; [Control_Name], [HelpText]
2. So, when the control is in focus I simple call a function "DisplayHelp"
3. The function will KNOW the controlname and set my  Me.Parent.HelpTextForField to [tblHelpUsers].[HelpText] as per the original VBA
4. Obviously I will no longer use the "tag" to hold help text.

What line should I put in my function to achieve the above?

Al contributions appreciated.

Create a Function that accepts the (a) the name of the Control to supply the Help Text for and (b) the name of the Control where you want to display that text:

Function ShowHelp(ControlName As String, DisplayControl As Textbox)

Dim s As String
s = Nz(DLookup("HelpText", "tblHelpUsers", "Contol_Name='" & ControlName & "'"),"")
DisplayControl = s

End Function

Now call your function like this in the GotFocus or Enter event:

ShowHelp Me.Name, Me.Parent.<DisplayControlName>

Where <DisplayControlName> is the name of the control on the parent form where you want to show the Help text.

I think you might want to make your help table a little more sophisticated.  Rather than just using control name as the unique identifier, I would also use form.  So the help table would be:

tblHelp
FormName (PK field 1)
ControlName (PK field 2)
HelpText (memo)

You might need other fields also so give it some thought.

Scott,

Your suggestion is work well ... but ...

Me.Name is displaying the form name (I want the control name)

I suspect that this may be because my datasheet is held as a subfolder within another folder.

QUESTION: Is there a better way to reference the actual control?
