I want to pass an array dimension via a parameter.  I want a single sub to work with calls in which the array dimension will change.  I get a "constant expression required" error when I try to call this:
rivate Sub SingleRcrd(ByRef iArrayBound As Integer, ByVal ThisSql As String)
    'On Error GoTo ErrorHandler
    
    Dim rs As ADODB.Recordset
    Dim i As Integer
    Dim UploadArr(iArrayBound)
    
    Set rs = New ADODB.Recordset
    rs.Open ThisSql, conn, 1, 2
    For i = 0 To iArrayBound
        UploadArr(i) = rs(i).Value
    Next i
    rs.Close
    Set rs = Nothing
    
    Set rs = New ADODB.Recordset
    rs.Open ThisSql, srvr_conn, 1, 2
    For i = 0 To iArrayBound
        rs(i).Value = UploadArr(i)
    Next i
    rs.Update
    rs.Close
    Set rs = Nothing
    
    Exit Sub
ErrorHandler:
    Beep
    ErrorHandler
End Sub

Open in new window


with this:
    sql = "SELECT EventName, EventDate, Club, Website, Weather, Comments, FeeIncrDate, TimingMethod, EventDirID, ShowOnline, "
    sql = sql & "OnlineReg, WhenShutdown, FeeIncrDate FROM Events WHERE EventID = " & lEventID
    Call SingleRcrd(12, sql)

Open in new window


What am I doing wrong?

I suspect it is because you are passing the parameter byref and then using it to try and define an array which I suspect is where the error is occurring. Can't see why you need to pass byref so do you get the same error if you pass the parameter byval.

use REDIM instead of DIM for the array, this tells the compiler that the dimension can be altered.

Another option is to use an xml object

Like Banthor says, use Dim, then ReDim. Change line 6 from

Dim UploadArr(iArrayBound)

to

Dim UploadArr()
ReDim UploadArr(iArrayBound)

Open in new window
