Using Objects in a Method

[Crazy4Cy]

I have some procedures I want to store in a module and call up to use in the form.

My problem is that the radio buttons are not being transferred into the module. I think I need a line of code at the beginning of the method so it has access to all the objects created in the form.

The error I am getting is:
[rb#] "is not declared. It may be inaccessible due to its protection level"

rb# are radio buttons that are being used in the main form.

form:

'uncheck boxes
        Call uncheckradiobuttons()

method
(rb# is underlined showing that is incorrect):

Public Module Module1
 
    Public Sub uncheckradiobuttons()
        rb11.Checked = False
        rb12.Checked = False
        rb13.Checked = False
        rb14.Checked = False
        rb21.Checked = False
        rb22.Checked = False
        rb23.Checked = False
        rb24.Checked = False
        rb31.Checked = False
        rb32.Checked = False
        rb33.Checked = False
        rb34.Checked = False
        rb41.Checked = False
        rb42.Checked = False
        rb43.Checked = False
        rb44.Checked = False
        rb51.Checked = False
        rb52.Checked = False
        rb53.Checked = False
        rb54.Checked = False
        rb61.Checked = False
        rb62.Checked = False
        rb63.Checked = False
        rb64.Checked = False
    End Sub
 
 
End Module

Yes, that's right. What you are missing is arguments to the method. Frankly, you almost certainly don't want to be doing this, as it violates the very spirit of object oriented programming, but the way to do it would look kind of like this:

Public Sub uncheckradiobuttons(frm As <your form type here>)        
 frm.rb11.Checked = False        
 frm.rb12.Checked = False     
End Sub

The problem is that such a method will only work if you supply it an instance of <your form type here>. Therefore, the method might as well be a method that is part of <your form type here>, rather than being over in a module. Of course, you could change that argument to be:

frm As Form

in which case it would take ANY form, but if the form you passed in didn't happen to have all those controls, the method would throw an exception. Therefore, there is no good reason to have that method anywhere other than as part of the form.

Thanks for your help. I guess even though it isn't advised and doesn't make a lot of since, I would still like to store some procedures in a method so the form is cleaner and easier to follow (this is for a homework assignment).

I did this:

Public Module Module1
 
    Public Sub uncheckradiobuttons(frm As Form1)
        frm.rb11.Checked = False
        frm.rb12.Checked = False
        ...
    End Sub
End Module

However, now this line isn't working:

'uncheck boxes
        Call uncheckradiobuttons()

It says:
Argument not specified for parameter 'frm' of 'Public Sub uncheckradiobuttons(frm as Form1)'.

Take a look at using #Regions to organize code in a file. You can also make use of partial classes to move parts of the code into other files without having it in a module.

As for the problematic line, you aren't passing a form to it, and it requires one. Have you not covered arguments, yet?

The proper call would be:

uncheckradiobuttons(Me)

as long as you are calling it from some instance of Form1 (which you probably are). Also, the Call word is never needed and does nothing, so you can always leave it out.
