Hi all,

I am new to Ruby. I just wonder how I can concatenate all the lines from
one file and let them become one string.

Thanks,

Li

File.read("/path/to/file")

How about:

a=File.open("/home/n6tadam/.xsession").read.gsub!('\n', ' ')

I've substituted the newlines for spaces -- but you can do whatever you
want with it.

Or maybe

File.readlines("xorg.conf").join(' ').gsub!("\n",' ')

I don't quite follow but if the code is not in the class/userform that
contains the procedures, change 'Me' to an object reference that refers to
the class, eg

CallByName cls, sProc, VbMethod
where 'cls' refers to the class that contains the proc's

However if you are calling in the same class or userform as the procuderes,
indeed use the 'Me' keyword to refer to the class/userform
CallByName Me, sProc, VbMethod

PS yes, use the CallByName method if you need to call procedures in class or
userform, App.Run method wouldn't work

Again I don't quite follow, is both "CommandButton" & z & "_Click" and the
CallByName code located in Class1. If so the code you posted should work,
assuming a Public procedure named
"CommandButton" & z & "_Click"
exists in the class

If you are trying to call ButtonGroup_Click, why not simply
Me.ButtonGroup_Click
or
cls.ButtonGroup_Click

See "CallByName" in help.

If I follow, ButtonGroup_Click() is in Class1 and Command#_Click() is in a
Userform, seems like a strange setup.

When you create Class1 pass a reference of the form, eg

assuming you are creating the class from within the form

' in the form, say in the initialize event
Set c = New Class1
Set c.propFrm = Me
c.aa

' in class1
Private moFrm As Object ' top of module

Public Property Set propFrm(oFrm As Object)
Set moFrm = frm
End Property

Public Sub ButtonGroup_Click()

CallByName moFrm, "CommandButton" & z & "_Click", VbMethod
End Sub

If the reference that store the class is not maintained in the userform, the
class needs to be destroyed before unloading the form, or rather in
particular 'moFrm' needs to be released.

It's difficult to understand what you have overall, but I suspect you might
be better trapping all your button events in a WithEvents class. That means
you only need write the Click event once for all your buttons.
