MIcrosoft, Access, 2003, VB - Populate an array from record set - Part Two, Get errors... "Type Mismatch" OR "Can't Assign to Array"

All I want to do is display the Record Set on screen (only if records are found) in table format or perhaps print it; which ever is easier.

However; I continually get one of these errors... "Type Mismatch" OR "Can't Assign to Array"

I have found a couple of previous questions that are good examples, however neither solution resolves my problem...


My code is attached.
Function FindDuplicates()
   Dim DB As Database
   Dim TheRecordSet As Recordset
   Dim RecordSetArray() As Variant     '<----- Related to error
   Dim NumOfRecords, RSRows, RSCols As Long
   Dim ModuleName, ErrorText, SQLQuery1 As String
   ' Initialize Error Routine
   On Error GoTo ThreeStoogages
   ModuleName = "FindDuplicates()" & Chr(10) & Chr(13)
   ErrorText = ModuleName & Chr(13) & Chr(10) & "Initialize All Variables"
   Set DB = CurrentDb()
   NumOfRecords = 0
   MsgBox "Begin VB Module Process: " & ModuleName & Chr(13) & Chr(10) & "Is used to identify duplicate records", vbInformation, "VB Module Execution"
   ' The SELECT Query
   SQLQuery1 = "SELECT blah, blah, blah..."
   ' MsgBox SQLQuery1, vbInformation, "SQLQuery1 Variable Contents"
   ' Create the RecordSet
   ErrorText = ModuleName & Chr(13) & Chr(10) & "Initialize Record Set"
   Set TheRecordSet = DB.OpenRecordset(SQLQuery1, dbOpenSnapshot)
   NumOfRecords = TheRecordSet.RecordCount
   ' Store the Record Set into an Array
   ErrorText = ModuleName & Chr(13) & Chr(10) & "Store the Record Set in an Array"
   Set RecordSetArray = TheRecordSet.GetRows(NumOfRecords)     '<----- Error occurs here
   ' Get the Array Column and Row Count
   ErrorText = ModuleName & Chr(13) & Chr(10) & "Get the Column and Row counts in the Array"
   RSCols = UBound(RecordSetArray, 1) 'Returns the Number of Columns in the Record Set - I have 9 columns
   RSRows = UBound(RecordSetArray, 2) 'Returns the Number of Rows in the Record Set - I have 120 records
   ' For the Error Routine
   ErrorText = ModuleName & Chr(13) & Chr(10) & "Check for empty Record Set"
   If TheRecordSet.BOF And TheRecordSet.EOF Then
      MsgBox ModuleName & Chr(13) & "No duplicate records found.", vbInformation, "Successful VB Module Execution"
      Exit Function
      ' Display the Record Set on screen
      ErrorText = ModuleName & Chr(13) & Chr(10) & "Display Record Set"
      MsgBox ModuleName & Chr(13) & "Duplicate records found.", vbInformation, "Successful VB Module Execution"
      ' Write any display code here as needed
   End If
   MsgBox ModuleName & "Found " & NumOfRecords & " Duplicate Records", vbInformation, "Successful VB Module Execution"
   Exit Function
' Error Routine
ThreeStoogages: MsgBox "Error Type: " & Error() & Chr(13) & Chr(10) & ErrorText, vbInformation, "Un-Successful VB Module Execution"
End Function

Try declaring your array differently:

Dim RecordSetArray As Variant     '<----- Related to error

Note also you may need to remove teh Set call:

RecordSetArray = TheRecordSet.GetRows(NumOfRecords)

Thanks, I use this declaration... Dim RecordSetArray() As Variant ...and removed the word SET per your sugestion and it worked! That explains why I coulsd not figure it out, it wasy to easy.

Now all I need to do is display the array in a table or grid, any suggestions (point me in the right direction)?
