Hi all,

anybody knows how to (sucessfully :-) use the addcollection-method in Visual Basic?
Sample (want to get all sequence charts of a model):

Private Sub Form_Load()

Dim g_oRatRos As New RationalRose.RoseApplication

' insert path to existing model with seqence charts
g_oRatRos.OpenModel "D:\Programme\Rational\Rose\testDM.mdl"

Dim AllCats As Integer
Dim alltheSeqCharts As New RoseScenarioDiagramCollection
Dim SeqChartColl As RoseScenarioDiagramCollection
Set theCategories = g_oRatRos.CurrentModel.GetAllCategories()

For AllCats = 1 To theCategories.Count
    Set SeqChartColl = theCategories.GetAt(AllCats).ScenarioDiagrams
    
    If SeqChartColl.Count > 0 And Not (SeqChartColl Is Nothing) Then
        alltheSeqCharts.AddCollection SeqChartColl
    End If
    
Next AllCats

g_oRatRos.Exit
Set g_oRatRos = Nothing

End Sub


The sample code says: Parameter 1 contains an invalid value
Well I don't believe this since i've checked value of collection in debugger.
Also iteration works well with this collection! Why not adding?

Thanks in advance
Rainer

P.S.: Of Course I have a reference to the rose typelib
