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

Posted on 2007-11-28

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)?
