Function FindAllByType and FindAllByTypeEx in SAP GUI Scripting

In this post I present two functions to detect all controls of one type of a collection, called FindAllByType and FindAllByTypeEx. The function FindAllByType has the parameters obj which describes a collection of objects and strType which describes the type of the control as string, e.g. GuiLabel. The function FindAllByTypeEx has the parameters obj which describes a collection of objects and lngType which describes the type of the control as long, e.g. 30 for GuiLabel. Both delivers an array of objects of the required type of the control.
