Hi,

I created a simple program to get the ComputerName. I execute the same code
in the constructor as in an OnClick-event of a button. This program works 
fine on my computer (WinXP). However, when I execute this program on a 
different computer, with Windows Me, everything works fine in the OnClick-
event, but when executing GetComputerName in the constructor, I get error 
87: The parameter is incorrect.

Does anyone know why this is?

regards,

Koen
