Topic: GetSelection Error

[tfieker]

Hello,
Where is the error in the GetSelection below using filters?
The "acSSPrompt.Status" returns error using ==>>  acTypValAr.SetValue(New TypedValue(DxfCode.ExtendedDataAsciiString, "P"), 2)

The entity XData in the blockReference is:
       Registered Application Name: DEVICE
       Code 1000, ASCII string: P
       Code 1000, ASCII string: UPD2


The code:
                Dim acTypValAr(2) As TypedValue
                acTypValAr.SetValue(New TypedValue(DxfCode.Start, "INSERT"), 0)
                acTypValAr.SetValue(New TypedValue(DxfCode.ExtendedDataRegAppName, "DEVICE"), 1)
                acTypValAr.SetValue(New TypedValue(DxfCode.ExtendedDataAsciiString, "P"), 2)

                Dim acSelFtr As SelectionFilter = New SelectionFilter(acTypValAr)
                Dim pso As New PromptSelectionOptions
                pso.MessageForAdding = "SELECT THE DEVICES"
                Dim acSSPrompt As PromptSelectionResult
                acSSPrompt = ed.GetSelection(pso, acSelFtr)

Thanks,

You can only use XData's application name as filter.

I understand, however for a Polyline the code below works correctly:

                    acTypValAr.SetValue(New TypedValue(DxfCode.Start, "LWPOLYLINE"), 0)
                    acTypValAr.SetValue(New TypedValue(DxfCode.ExtendedDataRegAppName, "ARANHA"), 1)
                    acTypValAr.SetValue(New TypedValue(DxfCode.ExtendedDataAsciiString, "JUMPER"), 2)

The throttling is only happening for BlockReference.

Same situation here.
According to the documentation, you can filter XData only by the application name (DxfCode.ExtendedDataRegAppName).
But for some situations it works to filter in addition to the name (DxfCode.ExtendedDataRegAppName) also by value (DxfCode.ExtendedDataAsciiString).
From what I've tested, filtering by value works for MText, Table, Polyline and Ellipses. Does not work for Insert, Line, Arc, Circle.

Yes, the same for me.
Thank you all!
