'It is best to call this procedure from the unload event

'of your main form. How do you close your Visual Basic program?

Do you use the End method? In this tip I will explain why
using the End method is not the best way to close your
program. It is an undocumented fact that using the End
method does not completely remove all forms from memory.
This means that your program does not give up all resources
to other processes when it is closed using the end method.
The only way to completely shut down the program is to
unload each of the forms using the Unload method. Here is
some code that loops through all loaded forms and unloads
them one by one. As soon as no forms are loaded, your
program has been closed.
