Hi,

I'm new at .NET for Autocad. I try to convert my VBA codes to .NET. But I have some troubles. I can use the codes below without any errors at VBA but it gives an error on .NET

VBA Codes:

Dim oSset As AcadSelectionSet
Dim FilterType(3) As Integer
Dim FilterData(3) As Variant
...

FilterType(0) = -4
FilterData(0) = "<OR"
FilterType(1) = 0
FilterData(1) = "LINE"
FilterType(2) = 0
FilterData(2) = "LWPOLYLINE"
FilterType(3) = -4
FilterData(3) = "OR>"
...

oSset.SelectOnScreen FilterType, FilterData

I try to convert them like this;

Dim oSset As Autodesk.AutoCAD.Interop.AcadSelectionSet
Dim FilterType(3) As Object
Dim FilterData(3) As Object
...
FilterType(0) = -4
FilterData(0) = "<OR"
FilterType(1) = 0
FilterData(1) = "LINE"
FilterType(2) = 0
FilterData(2) = "LWPOLYLINE"
FilterType(3) = 4
FilterData(3) = "OR>"
...
[color=red]oSset.SelectOnScreen([/color][color=red]FilterType, [/color][color=red]FilterData)[/color]

and it gives an error on "selectonscreen" line. The error is "Invalid argument FilterType in SelectOnScreen"

 

I also try "Short " and "Integer" variable types for "FilterType" but nothing change.

I would appreciate if you can help.
