This article was previously published under Q130277



SYMPTOMS
Passing too many parameters to the function WPARENT as in: ? WPARENT(" ", ) results in different error messages in versions 2.x and 3.0. Error message # 1230 is returned in Visual FoxPro 3.0 as:

Too many arguments.

whereas error message # 214 is returned in previous versions as:

Window has not been defined.



STATUS
This behavior is by design.



MORE INFORMATION
Visual FoxPro checks the number of arguments in the function before checking for the existence of the window in question. FoxPro 2.x checked to see if the window existed before it checked to see if the function had too many arguments. FoxPro 2.x ignored a second argument.

Steps to Reproduce Problem
Issue the command: ? WPARENT("no_window",10) where the window "no_window" has not been defined.

Notice different error messages are returned in 2.x and 3.0.
