Dear all,

I am using arcmap 9.3 and vb.net i need to delete the vertex pragmatically. i have the feature and index of delete vertex but i dont know how to delete the vertex any one give me the sample code for delete vertex. i am using following code its not working.

Function deletevertex(ByVal index As Integer, ByVal pointCollection As IPointCollection)

Dim editorUID As UID

editorUID = New UID

editorUID.Value = "esriEditor.Editor"

Dim editor As IEditor

editor = (papp.FindExtensionByCLSID(editorUID))

Dim editSketch As IEditSketch

If editor Is Nothing Then

Exit Function

End If

editSketch = CType(editor, IEditSketch)

If index = -1 Then

End If

Dim sketchOperation As ISketchOperation

sketchOperation = New SketchOperation

sketchOperation.MenuString_2 = "Delete Vertex"

sketchOperation.Start(editor)

pointCollection = editSketch.Geometry

pointCollection.RemovePoints(index, 1)

editSketch.RefreshSketch()

sketchOperation.Finish(editSketch.Geometry.Envelope)

End Function

above code show the error of

"the index either too small or too large".

Note:

If i am select the Feature using "modifying Feature" that time vertex deleted successfully. if i am select the vertex using "new feature creation " that time only the index either too large or too small error showing.
