VBA DoCmd.OutputTo With QueryDef - ms-access

Question

I've been looking a while now for a solution to export a query with open parameters. I need to export a Query as a Formatted Excel Spreadsheet and can't create additional Tables, Queries, Forms, or Reports to the Database being used. I use DoCmd.OutputTo as it exports a formatted query unlike DoCmd.TransferSpreadsheet however I can't seem to export the query with defined parameters. I need to include the parameters or else the user will be forced to input the start and end date three times a piece as the database for some reason asks for the startDate and endDate twice and in order to keep the excel spreadsheet and the subsequent outlook section consistant i would have to ask the user to input their previous parameters again
Sub Main()
On Error GoTo Main_Err

DoCmd.Hourglass True
Dim fpath As String
Dim tname As String
Dim cname As String
Dim tType As AcOutputObjectType
Dim tempB As Boolean
fpath = CurrentProject.path & "\"
'tType = acOutputTable
'tname = "APPROVED SWPS FOR LOOK AHEAD & BAR CHART"
tType = acOutputQuery
tname = "ASFLA&BC Query"
cname = "Temp BPC Calendar"
Dim qdfQry As DAO.QueryDef
Dim strStart As String
Dim strEnd As String
Set qdfQry = CurrentDb().QueryDefs(tname)
'strStart = InputBox("Please enter Start date (mm/dd/yyyy)")
'strEnd = InputBox("Please enter Start date (mm/dd/yyyy)")
qdfQry.Parameters("ENTER START DATE") = FormatDateTime("6/30/12", vbShortDate) 'strEnd
qdfQry.Parameters("ENTER END DATE") = FormatDateTime("7/1/12", vbShortDate) 'strStart
tempB = Backup(fpath, qdfQry, tType)
If (Not tempB) Then
MsgBox "Excel Conversion Ended Prematurely..."
Exit Sub
End If
' tempB = sendToOutlook(qdfQry, cname)
' If (Not tempB) Then

The SQL currently given looks like similar to below with omitted fields for for clarity
PARAMETERS [ENTER START DATE] DateTime, [ENTER END DATE] DateTime;
SELECT [SWPS].STATION,
[SWPS].START_DATE,
[SWPS].END_DATE,
FROM [SWPS]
WHERE ((([SWPS].STATION)
Like ("*"))
AND (([SWPS].START_DATE)<=[ENTER END DATE])
AND (([SWPS].END_DATE)>=[ENTER START DATE])
AND (([SWPS].SWP_STATUS) In ("A","P","W","T","R")));

I suggest you change the sql of the query.
Dim qdfQry As DAO.QueryDef
Dim strStart As String
Dim strEnd As String
''You could use a query specifically for this
Set qdfQry = CurrentDb.QueryDefs(tname)
sSQL=qdfQry.SQL
NewSQL = "SELECT [SWPS].STATION, [SWPS].START_DATE, [SWPS].END_DATE, " _
& "FROM [SWPS] WHERE [SWPS].STATION Like '*' " _
& "AND [SWPS].SWP_STATUS In ('A','P','W','T','R') " _
& "AND [SWPS].START_DATE)<=#" & Format(DateStart, "yyyy/mm/dd") & "# " _
& "AND [SWPS].END_DATE)>=#" & Format(DateEnd, "yyyy/mm/dd") & "#"
qdfQry.SQL = NewSQL
''Do the excel stuff
''Reset the query
qdfQry.SQL = sSQL
