Copy Module to External Workbook

[Partjob]

I have been trying for some days to copy a module to an external workbook with VBA. I have about 40 workbooks that have the same format. although I developed these sheets. I am not the person who uses them. I have to on occasion alter the code for some reason, its getting tiresome.

I don't think I can use the personal workbook method for this as it is not me using the workbooks. I don't even know some of the people that use them. This courses me problems because of the number of workbooks. I want to be able to maintain the code by having to write it once and propagate it through the necessary files via the VBA.
I have code from C Pearson that copies a module to another workbook.
I have posted this here just in case. Most threads on this subject just direct you here any way.

Function CopyModule(ModuleName As String, _
    FromVBProject As VBIDE.VBProject, _
    ToVBProject As VBIDE.VBProject, _
    OverwriteExisting As Boolean) As Boolean
    '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
    ' CopyModule
    ' This function copies a module from one VBProject to
    ' another. It returns True if successful or  False
    ' if an error occurs.
    '
    ' Parameters:
    ' --------------------------------
    ' FromVBProject         The VBProject that contains the module
    '                       to be copied.
    '
    ' ToVBProject           The VBProject into which the module is
    '                       to be copied.
    '
    ' ModuleName            The name of the module to copy.
    '
    ' OverwriteExisting     If True, the VBComponent named ModuleName
    '                       in ToVBProject will be removed before
    '                       importing the module. If False and
    '                       a VBComponent named ModuleName exists
    '                       in ToVBProject, the code will return
    '                       False.

I have coloured red the part I have put in where I think I have to "Set Parameters" I am just not sure about this bit. I can not get it right. I don't understand how these Parameters work. How do you state in the code where the target workbook is. the only one I think I have correct is the overwrite existing.

I am just trying to get this to work at the moment just as a test so I can get a better understanding of what is going on. I have a folder on my desktop with 2 workbooks in it. One called "Original" I have the above code in Module 1 in this workbook. In Module 3 I have the code I want to copy to the other workbook called "Workbook"
I try and call this function in Module 2 with the very simple

Sub CopyCode()
Call CopyModule
End Sub

It seems I have to state the variables in the call statement, I can't get this right either.
I have the feeling this all going to blatantly obvious once I have right.

My goal is to have this loop through all the workbooks and change the code when necessary instead of me opening each and every workbook and altering the code.
Thanks a lot for any help or advise.

thank you. i am sure it will be a big process that turns out simple.

Every module can be saved as a .bas file and can be imported later.

1) Copy file to new location
2) Import the .bas file.
3) Open the file once the module is imported.

Does this make sense.

 

[drawworkyhome]

it does. i think what it really boils down to is my code structure is "faulty". what i mean by that is, when i started this project, i did not do my due diligence and create a flow to the program. i just jumped in both feet and started swimming.

so, i am in the process of doing just that which will mean re-writing what i have. there has to be a simpler way to do what i want.
