https://community.blueprism.com/t5/Product-Forum/Version-of-the-VB-engine-BluePrism-V5/m-p/85993#M36920 Hi,   When I use the function "InStr" I have this: 'Public Sub InStr (InText as String, Search_String as String, Start_Byte as Decimal, Compare_Method as Decimal, ByRef Position as Decimal)'. With the arguments: "Start_Byte As Decimal, Compare_Method As Decimal, ByRef Position As Decimal" required. When I consult the function on the Microsoft doc, I get InStr (Int32, String, String, CompareMethod) > 4 arguments instead of 5 including 2 required and not 3!   What is the version of the VB engine behind BluePrism V5 ?!   Thx Thu, 01 Mar 2018 22:37:00 GMT BordessoullesVi 2018-03-01T22:37:00Z https://community.blueprism.com/t5/Product-Forum/Version-of-the-VB-engine-BluePrism-V5/m-p/85993#M36920 Hi,   When I use the function "InStr" I have this: 'Public Sub InStr (InText as String, Search_String as String, Start_Byte as Decimal, Compare_Method as Decimal, ByRef Position as Decimal)'.
