MI-L How to run a VB program in an exclusive window

[MAGS (Mapping Global Solutions)]

Hi all !   First of all, thanks to all who have answerd me how to run an .exe file in a syncronc way!   I forgot to add an additional problem and this is that the .exe file (form) must to be exclusive, so the user does not be able to do another task (in mapinfo of course) until the VB program has finished. Excatly like the Layer window for example.   Regards, Alejandro
