Set cell value with VBA - ms-access

Question

I scan and save images with Wia using VBA in Microsoft Access.
The filepath to the saved image should be set as the value of the current cell.
I can't figure out how to do this but it seems like an easy task after learning how to use Wia.
Here is my current code that scans a document.
Function scanImage() As String
Dim imagePath As String
Dim folder As String
folder = "C:\Users\username\Pictures\scans\"
Dim tempName, obj
Set obj = CreateObject("Scripting.FileSystemObject")
tempName = obj.GetTempName
Dim filename
filename = Now
filename = Replace(filename, ".", "_")
filename = Replace(filename, " ", "_")
filename = Replace(filename, ":", "_")
imagePath = folder & filename & ".jpg"
Dim dev As Device
Dim wiaDialog As New WIA.CommonDialog
Dim wiaImage As WIA.ImageFile
Set dev = wiaDialog.ShowSelectDevice
Set wiaImage = wiaDialog.ShowAcquireImage
wiaImage.SaveFile (imagePath)
scanImage = imagePath
End Function

As comments have said - there's no cells in Access, and definitely no active cell.
You can add a record to a database using either of the methods below, but how do you plan on extracting that information again?
In Excel you just ask for the data in cell A1 for example, but in a database you generally ask for the data from a field or fields where another field on that same record is equal to some other values (either by supplying the 'other value' directly or by referencing other tables within the database).
So, for example, in your database you'd ask for the file paths of all files scanned on a certain date, or have some kind of description field to identify the file.
This would be written something like:
SELECT FilePath FROM Table2 WHERE DescriptionField = 'MyPhoto'
Anyway, the answer to get that single text string (imagepath) into a new record in a table is:
Sub InsertValueToTable()
Dim imagepath As String
imagepath = "<file path>"
'NB: The table name is 'Table2', the field (column) within the table is called 'FilePath'.
'One way to do it:
'DoCmd.RunSQL "INSERT INTO Table2(FilePath) VALUES ('" & imagepath & "')"
'Another way to do it:
Dim rst As dao.Recordset
Set rst = CurrentDb.OpenRecordset("Table2")
With rst
.AddNew
rst!FilePath = imagepath
.Update
.Close
End With
Set rst = Nothing
End Sub
Note - if you use a Text field in the database you'll be limited to 255 characters.
