Since I am pretty new to this forum, I hope I post the message at the 
right place. If not, please let me know.

I am working on a MDI form and Child form. I have a MDI contains the 
coolbar which you can open /save files. on the child form, it is a 
reservation form for the type of cars you need. 

Basically, what I am trying to do is collecting all the information from 
child form (text of textbox and combobox) to save it into a database when 
the save button is trigged on the MDI form. What I have problems is how to 
pass the variables from Child form to MDImain form since all the 
information is collected from child form, but my procedure for saving 
these information is trigged on the main form. 

Thanks, Any suggestion is appreciated.
