VB syntax

ok .... first problem i have solved...i changed its name to cmdRoy.
then its working..its caption is changing as soon as i am clicking..
thnks


but about second question..... how u people write code??? mixed case/ all in lower case???

i have seen it does not matter whether i use ,ixed or lowercase.

bcoz i checked with

msgbox "hi"
and MsgBox " hi"

at the command button... both giving the same result.....but still i feel there is some rule????
in java there is rule that class name starts with capital letter(altough not necessary).... does VB HAS something like that???

No - VB is not case sensitive. If you type an objects/variable's name in lowercase, and the name is actually specified in upper case, then the Integrated development environment will automatically change it to match the declared object/variable. It's like I said earlier, if I have a form called frmMain, and I type in frmmain, then VB will recognize that as a valid name.
