Hi&nbsp;Carlos,&nbsp;  
&nbsp;&nbsp;  
&nbsp;Thanks&nbsp;for&nbsp;your&nbsp;post,&nbsp;this&nbsp;is&nbsp;because&nbsp;we&nbsp;set&nbsp;BaseShape.GeometryLibrary&nbsp;as&nbsp;GeometryLibrary.Unmanaged&nbsp;by&nbsp;default,&nbsp;&nbsp;would&nbsp;you&nbsp;please&nbsp;add:&nbsp;  
&nbsp;&nbsp;  
&nbsp;BaseShape.GeometryLibrary&nbsp;=&nbsp;GeometryLibrary.Managed;&nbsp;  
&nbsp;&nbsp;  
&nbsp;This&nbsp;should&nbsp;solve&nbsp;the&nbsp;problem,&nbsp;because:&nbsp;  
&nbsp;&nbsp;  
&nbsp;When&nbsp;using&nbsp;BaseShape.GeometryLibrary&nbsp;=&nbsp;GeometryLibrary.Managed,&nbsp;we&nbsp;use&nbsp;the&nbsp;NTS&nbsp;to&nbsp;check&nbsp;the&nbsp;data&nbsp;validation&nbsp;  
&nbsp;When&nbsp;using&nbsp;BaseShape.GeometryLibrary&nbsp;=&nbsp;GeometryLibrary.Unmanaged&nbsp;or&nbsp;BaseShape.GeometryLibrary&nbsp;=&nbsp;GeometryLibrary.Defualt,&nbsp;we&nbsp;use&nbsp;the&nbsp;Sqltype&nbsp;&nbsp;to&nbsp;check&nbsp;the&nbsp;data&nbsp;validation&nbsp;  
&nbsp;As&nbsp;Sqltype&nbsp;have&nbsp;a&nbsp;stricker&nbsp;validation-checking,&nbsp;some&nbsp;data&nbsp;will&nbsp;not&nbsp;pass&nbsp;SqlType&nbsp;validation&nbsp;check&nbsp;and&nbsp;the&nbsp;exception&nbsp;will&nbsp;be&nbsp;thrown.&nbsp;  
&nbsp;&nbsp;  
&nbsp;Hope&nbsp;it&nbsp;helps,&nbsp;

Hi&nbsp;Johnny,&nbsp;  
&nbsp;&nbsp;  
&nbsp;&nbsp;I&nbsp;guessed&nbsp;it&nbsp;so,&nbsp;but&nbsp;in&nbsp;6.0.260.0&nbsp;it&nbsp;already&nbsp;was&nbsp;already&nbsp;unmanaged&nbsp;as&nbsp;default.&nbsp;In&nbsp;fact&nbsp;I&nbsp;have&nbsp;been&nbsp;using&nbsp;unmanaged&nbsp;since&nbsp;you&nbsp;introduced&nbsp;the&nbsp;sqltypes&nbsp;library&nbsp;long&nbsp;time&nbsp;ago&nbsp;(back&nbsp;in&nbsp;5.5?).&nbsp;&nbsp;So&nbsp;It&nbsp;should&nbsp;be&nbsp;other&nbsp;the&nbsp;reason…

Hi&nbsp;Carlos,  
&nbsp;  
In&nbsp;this&nbsp;case,&nbsp;you&nbsp;should&nbsp;set&nbsp;it&nbsp;to&nbsp;Managed&nbsp;to&nbsp;pass&nbsp;the&nbsp;validation,&nbsp;the&nbsp;wkb&nbsp;is&nbsp;not&nbsp;recongnized&nbsp;as&nbsp;valid&nbsp;by&nbsp;Sql&nbsp;types&nbsp;but&nbsp;it’s&nbsp;valid&nbsp;by&nbsp;NTS.&nbsp;Here&nbsp;are&nbsp;the&nbsp;screencasts&nbsp;to&nbsp;show&nbsp;the&nbsp;differences.

Hi&nbsp;Edgar,&nbsp;  
&nbsp;&nbsp;  
&nbsp;&nbsp;I&nbsp;fully&nbsp;understand&nbsp;the&nbsp;difference&nbsp;between&nbsp;SQL&nbsp;Types&nbsp;and&nbsp;NTS,&nbsp;but&nbsp;the&nbsp;point&nbsp;here&nbsp;is&nbsp;that&nbsp;the&nbsp;same&nbsp;code&nbsp;specifying&nbsp;unmanaged&nbsp;(SQL&nbsp;Types)&nbsp;with&nbsp;6.0.260.0&nbsp;DLLs&nbsp;was&nbsp;working&nbsp;fine.&nbsp;  
&nbsp;&nbsp;  
&nbsp;&nbsp;Do&nbsp;you&nbsp;attempt&nbsp;to&nbsp;MakeValid&nbsp;the&nbsp;invalid&nbsp;features&nbsp;internally&nbsp;or&nbsp;is&nbsp;there&nbsp;any&nbsp;other&nbsp;way&nbsp;to&nbsp;overcome&nbsp;this&nbsp;without&nbsp;give&nbsp;up&nbsp;the&nbsp;use&nbsp;of&nbsp;SQL&nbsp;types&nbsp;and&nbsp;return&nbsp;permanently&nbsp;to&nbsp;NTS&nbsp;library?

I&nbsp;think&nbsp;you&nbsp;can&nbsp;use&nbsp;the&nbsp;valid&nbsp;shape&nbsp;files&nbsp;or&nbsp;override&nbsp;the&nbsp;LineStyle.DrawCore&nbsp;method&nbsp;in&nbsp;this&nbsp;case,&nbsp;and&nbsp;implement&nbsp;like&nbsp;below,

`Public Class MyLineStyle : Inherits LineStyle    Sub New(geoPen As GeoPen)        MyBase.New(geoPen)    End Sub    Protected Overrides Sub DrawCore(features As IEnumerable(Of Feature), canvas As GeoCanvas, labelsInThisLayer As Collection(Of SimpleCandidate), labelsInAllLayers As Collection(Of SimpleCandidate))        Dim validFeature As New Collection(Of Feature)        For Each feature As Feature In features            validFeature.Add(feature.MakeValid())        Next        MyBase.DrawCore(validFeature, canvas, labelsInThisLayer, labelsInAllLayers)    End SubEnd Class`

and&nbsp;I'm&nbsp;not&nbsp;sure&nbsp;when&nbsp;will&nbsp;we&nbsp;give&nbsp;up&nbsp;the&nbsp;NTS,&nbsp;but&nbsp;I&nbsp;think&nbsp;providing&nbsp;the&nbsp;valid&nbsp;data&nbsp;is&nbsp;necessary&nbsp;is&nbsp;the&nbsp;main&nbsp;part.

Hi&nbsp;Edgar,&nbsp;  
&nbsp;&nbsp;  
&nbsp;&nbsp;Providing&nbsp;valid&nbsp;data&nbsp;is&nbsp;fine&nbsp;when&nbsp;you&nbsp;own/control&nbsp;all&nbsp;the&nbsp;source&nbsp;shape&nbsp;files,&nbsp;this&nbsp;would&nbsp;be&nbsp;in&nbsp;a&nbsp;ideal&nbsp;world,&nbsp;unfortunately&nbsp;our&nbsp;is&nbsp;not,&nbsp;so&nbsp;the&nbsp;code&nbsp;should&nbsp;be&nbsp;protective&nbsp;instead&nbsp;of&nbsp;preventive.&nbsp;  
&nbsp;&nbsp;  
&nbsp;&nbsp;Thanks&nbsp;for&nbsp;the&nbsp;LineStyle&nbsp;code&nbsp;sample,&nbsp;but&nbsp;how&nbsp;can&nbsp;I&nbsp;use&nbsp;it&nbsp;within&nbsp;your&nbsp;BaseShape.CreateShapeFromWellKnownData&nbsp;used&nbsp;in&nbsp;ThinkGeo.MapSuite.Core.Layer.Draw(GeoCanvas&nbsp;canvas,&nbsp;Collection`1&nbsp;labelsInAllLayers)?&nbsp;I&nbsp;mean,&nbsp;I&nbsp;wish&nbsp;to&nbsp;continue&nbsp;using&nbsp;sql&nbsp;types&nbsp;library,&nbsp;to&nbsp;use&nbsp;the&nbsp;new&nbsp;dlls&nbsp;6.0.345.0&nbsp;or&nbsp;newer&nbsp;plus&nbsp;and&nbsp;use&nbsp;the&nbsp;not-under-my-control-shapefiles&nbsp;I&nbsp;have&nbsp;been&nbsp;using&nbsp;for&nbsp;a&nbsp;while&nbsp;now.&nbsp;Is&nbsp;it&nbsp;possible&nbsp;anyhow?

Carlos,&nbsp;  
&nbsp;&nbsp;
