Hi Everyone, I can’t seem to get UIShow to launch my screen. The names of the application extentions in my home directory are: TpsViewFSWControlScreen.dll TpsViewFSWControlScreen.gtpu.dll In Rapid I have this: * * * CONST string Name:=“TpsViewFSWControlScreen.gtpu.dll”; CONST string Type:=“ABB.Robotics.SDK.Views.TpsViewFSWControlScreen”; CONST string Cmd1:=“Init data string passed to the view”; PERS uishownum myinstance:=0; VAR num mystatus:=0; UIShow Name,TypeInitCmd:=Cmd1InstanceID:=myinstanceStatus:=mystatus; * * * Why does executing UIShow generate the following error? 41664 The typename is invalid for this assembly 2009-04-01 14:02:01 Task: T\_ROB1 The inparameter TypeName is invalid. The typename does not match the assembly.Status -5. Program Ref /SWV50\_Gantry/StirL/UIShow/483. {args: “T\_ROB1”, “TypeName”, “-5”, “/ SWV50\_Gantry/StirL/UIShow/483”, “ERR\_UISHOW\_FATAL”} ---

Hi Kevin, You should post this quetion inside Robot Application Builder Forum. Can you copy the declaration of your TpsView? .. it seems that it is something about the full name: NAMESPACE.NAME
