easy one - pass form and field to function

Public Function YourFunction (frm as form,TextBoxValue as string)

Select allOpen in new window

You call it like this

YourFunction Me, Me.textbox.name

Select allOpen in new window

Thank you - how do I think reference that form+field to update it with a certain value, in the function?

I am not 100% percent sure what you need,,,
I assume that you want to perform some operations in your function that will affect your form....
if this is correct then you need to modify the function to  like this

Public Function YourFunction (ByRef frm as form,TextBoxValue as string)

Select allOpen in new window

but better to give some more info about your function

I'm trying to do something like this in the function, but it is giving me an error:

Function ShowLink(thislink As String, thisform As Form, thiscontrol As String)

Dim sFilename as string
sFileName = Mid(thislink, iBackslash + 1, (Len(thislink) - iBackslash))
thisform.thiscontrol = sFileName

On the last line above, I'm getting error 2465, Application-defined or object-defined error...

Function ShowLink(thisLink as string) as string
ShowLink=  = Mid(thisLink , iBackslash + 1, (Len(thislink) - iBackslash))
End function

Select allOpen in new window

Then on the control you want to use it

me.thiscontrol = showlink(thisLink )

Select allOpen in new window

Also - when I'm passing the formname ('me'), I guess it is not fully referenced. Maybe this is part of the problem?

Also to reference to a control from a frm object

frm.controls(thiscontrol.name)

Select allOpen in new window

sorry, I'm still not getting this. can you pls be more specific on how I should correct the error?
Thanks!

Definitely covered the waterfront - great responses from real experts. I am grateful.
