Retreiving data from an Access Database using Microsoft Excel and VB macros

I've recently been given a project to fix which pulls data from tables in an Access database and pastes them into an Excel worksheet.

The problem I'm having is that it only copies some of the data.  There are 1700 records in the table of the databse but when pasted into Excel only pastes around 1500 rows.  The following code is used to import the cases but there doesn't appear to be any set range that stops it importing all of the records.

    '=================== Import Cases from Access ======================
    Set rst = New ADODB.Recordset
    rst.CursorLocation = adUseServer
    rst.Open Source:="Table_Cases", ActiveConnection:=cnn, CursorType:=adOpenDynamic, LockType:=adLockOptimistic, Options:=adCmdTable
    Worksheets("Escalation Workspace").Select 'Activate
    Range("A3").CopyFromRecordset rst

My main question would be is there any limit to the amount of data that can be pulled from Access?

Many thanks

Im not aware of any limits in this
as a test can u try this

first, perform a SELECT * FROM Table_Cases
it shouldnt make a different but try it anyway
then verify the number of records using recordcount property

rst.Open Source:="SELECT * FROM Table_Cases", ActiveConnection:=cnn, CursorType:=adOpenDynamic, LockType:=adLockOptimistic, Options:=adCmdTable

'now add ths
msgbox "Number of Records " & rst.RecordCount

What value do u get in the msgbox?
If u get -1, then try this

msgbox "Number of Records " & rst.RecordCount

Now what value do u get?

Next, try a looping method
Im trying to remember exact syntax of checking it but its something like this
Paste 1000 rows at a time

dim lRows as long

lRows = 3

do while rst.EOF = False
    Range("A" & lRows).CopyFromRecordset rst, 1000
    lRows = lRows + 1000

This is the CopyFromRecordset syntax.

returnValue = SomeRange.CopyFromRecordset(Recordset, MaxRows, MaxColumns)

CopyFromRecordset returns the number of rows copied.  So you can assign it to a variable to compare against the number of records in your recordset.

Is this a new excel sheet or are you pasting it into an existing one??
See if the missing rows contain NULL values.  Excel does not like NULLS.
