Open a CR10-Report from a CE10-Server via VBA

[MRR77]

Hi @all,
(first of all: I hope that I will be able to describe my problem...)

I'm looking for a way to open a report from the CE10-Server. Situation: A user-form in an Access-Database contains a tree-view-control and a list-box.
The logon on the CE10-Server works fine:

Set es = oSession.Logon(Environ("Username"), "verysecret", "CE10Servername", "secEnterprise")

Filling the tree-view seems to work too using code like:

objFolders = iStore.Query("Select * from CI_INFOOBJECTS Where " & _
  "SI_PROGID = 'CrystalEnterprise.Folder' AND SI_PARENTID=0")
TV.Nodes.Clear
j = 1
For i = 1 To objFolders.ParentInfoObjects.Count
  TV.Nodes.Add , tvwNext, "a" & CStr(objFolders.ParentInfoObjects(i).ID), objFolders.ParentInfoObjects(i).Title
Next

And getting the names for all reports in one of the clicked entries of that tree-view:

o = iStore.Query("Select * from CI_INFOOBJECTS " & _
  "Where SI_PARENTID=" & j & " AND SI_PROGID = " & _
  "'CrystalEnterprise.Report'")
If Err.Number = 0 Then
  LstReports.RowSource = ""
  For i = 1 To o.ParentInfoObjects.Count
    If o.ParentInfoObjects(i).ParentID = j Then
      LstReports.AddItem o.ParentInfoObjects(i).ID & ";" & o.ParentInfoObjects(i).Title
     End If
  Next
End If

My problem now is: The user clicks (or double-clicks) one of these report-names - and the program should open the report so that I can read some of the report-properties (formulas, field-names, groups, parameters, SQL-commands etc.)
How can I do this? Do I have to initialize an URIManager-variable? Or an InfoObject? How?
I'm looking now for days and weeks to find a solution...

It would be great if anyone can give me a clue how the problem can be solved.
Looking for your hints and answers
