Here's what I am trying to do 1. first simulate heavy load on the n/w interface using a script i wrote. The script just copies files over the network in a loop. 2. Then I call the download method of update object with bSilent set to true.
Now I was expecting the b/w utilization for this update to be very low or atleast at such a level that it doesn't slow down my script's transfer rate. but the b/w utilization was really high and it took over a lot of bandwidth from the script. (about half).
Another problem I am having is that no information about the scheduled or partially downloaded updates persists across multiple sessions of ISDM.exe. Although the link above says that even in an event of user logging off, no information is lost.
the code for invoking the agent follows
FORM1: Private Sub Command3_Click() Dim pAgent As New DWUpdateServiceLib.Agent Dim updateCollection As DWUpdateServiceLib.Updates Dim updateInstance As DWUpdateServiceLib.Update
pAgent.DisplayMessages prodCode.Text
If pAgent.IsConnected() Then Set updateCollection = pAgent.EnumUpdates(prodCode.Text)
MsgBox updateCollection.Count For iIndex = 1 To updateCollection.Count Dim choice As VbMsgBoxResult Set updateInstance = updateCollection.Item(iIndex) choice = MsgBox(updateInstance.QueryValue(Title), vbYesNo) If choice = vbYes Then [SIZE=3]Form2.download updateInstance[/SIZE] End If Next End If ------------------------------------------------- code in FORM2
Public WithEvents CurrUpdateInst As DWUpdateServiceLib.Update
Public Sub download(ByRef updateInst As DWUpdateServiceLib.Update) Set CurrUpdateInst = updateInst Form2.Visible = True ProgressBar1.Value = 0 ProgressBar1.Max = CurrUpdateInst.DownloadSize + 1 CurrUpdateInst.download True End Sub
Private Sub CurrUpdateInst_OnProgressChanged(ByVal nBytes As Long, ByVal nPercent As Long, ByVal strTransferRate As String, ByVal strTimeRemaining As String)
