Vba To Refresh Specific External Connections

[shayanan]

I have 3 External web Connections. I use code below to start and stop automatically refresh, but it refreshed All connections.

I need 2 Things:
1- just Refreshing One of Connections: "ConnectionA".
2- Use a cell value to Assign Seconds to repeat refreshing. for example value of cell "A2" is 45, so auto refresh every 45 second.

Public RefreshTime As Double
Public Const Seconds = 30 'Input Refresh Interval in seconds

Sub StartRefreshLoop()
    ' User Message indicating loop is beginning
    MsgBox "Refreshes will begin to occur at " & the designated interval of " & Seconds & " seconds"
    ' Call the first Refresh
    Call StartRefreshes
End Sub

Sub StartRefreshes()
    ' Calculate Next Refresh Time
    RefreshTime = Now + TimeSerial(0, 0, Seconds)
    ' Trigger a Refresh with OnTime function
    Application.OnTime _
    EarliestTime:=RefreshTime, _
    Procedure:="RefreshConnections", _
    Schedule:=True
  End Sub


Sub RefreshConnections()
    ' Refresh Data Connections
    ThisWorkbook.RefreshAll
    ' Start Timer Over Again
    Call StartRefreshes
End Sub


Sub EndRefreshLoop()
    ' On Error Resume Next
    Application.OnTime _
    EarliestTime:=RefreshTime, _
    Procedure:="RefreshConnections", _
    Schedule:=False
    ' User Message indicating loop has ended
    MsgBox "Refreshes are no longer occurring"
End Sub

One of the properties of each 'web-connection' is its 'refresh rate'.
You con't need VBA to do the refreshing.

You are right. best way to activate regularly refresh is on "Properties". but in this way it get refresh until you uncheck it again. I mean when you need 3 Hours a day to refresh 1 per minutes, and after that hours, you should disable update and do it day by day.
I was looking for an easy and more accessible way by press a button to start 30 second or 1 minuets update and after for example 15PM by pressing button refresh stopped.

You're using refresh all in your code, you can refresh on a table by table approach, for example (depending on what kind of query it is):

Range("H2").ListObject.QueryTable.Refresh    'the query associated with a Table at a cell
Sheets("Sheet1").ListObjects("Table1_2").QueryTable.Refresh
Range("Table1_2").ListObject.QueryTable.Refresh    'don't need to refer to the sheet
' without a Table (listObject):
Range("A1").QueryTable.Refresh
Sheets("Sheet1").QueryTables(1).Refresh
Sheets("Sheet1").QueryTables("mytblName").Refresh
