Hi,
If the control's name is stored in a string one can iterate through the
controls collection of a form to access the control.

dim s as string="chkIsValid"
dim chk as CheckBox
for each ctl as control in me.controls
if typeof ctl is CheckBox andalso ctl.name.tolower=s.tolower then
chk=ctype(ctl,Checkbox)
exit for
end if
next

Is there a faster (and more elegant) way to do so?

Thanks

Hi Leo,

Since s is constant you don't need to convert to lower case in each
iteration...

Also, if you need to compare strings case-independent, use
String.Compare(ctl.Name, s, True) where the third parameter is IgnoreCase.
It is faster that converting to lower case and uses less memory.

All that said, the faster way is:

chk = Me.Controls.Item("chkIsValid")

:-)
