Need a soluce to find line or file where is my error ...

Hello , (again !)

Is there any easy soluce to find error line with OpenDCL tools ???

Because

An OpenDCL function argument processing exception has occured !
Error: no object instance
Function : dcl_Control_SetTitleBarText
Argument : 3

Does not talk me about where and maybe why ????

It should be easier if we could see wich parameter was send .... like this :

Parameter 1 : "Boite"
Parameter 2 : "BETON2"

Thanks.

Many types of arguments cannot be represented as strings, so it wouldn't be generally possible to do what you suggest. I think a better approach is to set a breakpoint in the VLisp debugger and inspect the function arguments under the debugger if there is any question.
