Bypass workbook_open when opening from word - vba

Question

I am working on a project that requires both an excel document and a word document. I have fully programmed the excel document to work using UserForms, one of which opens automatically when opening the document. (see code below)
Private Sub Workbook_Open()
frmOpen.Show
End Sub
The word document has been programmed to read data from this excel document and write it into a report. (see code below)
Private Sub cmdAutomatic_Click()
Dim objExcel As New Excel.Application
Dim exWb As Excel.Workbook
Dim selectID As String
Set exWb =objExcel.Workbooks.Open("C:\ Path")
exWb.Close
''Data is written into the document here
Set exWb = Nothing
Unload Me
End Sub
The issue is that every time this button is pressed it opens the user form from the excel document and halts the other code until the user form is closed. Is there a way to only have the User Form open when it.
I have tried
Application.EnableEvents = False
However this just returns a method or data member not found (so I assume that this has to be run excel to excel?)
Sorry if this question has already been answered, I could not find anything that addressed this issue. Also sorry if this has a really simple solution, this is for a school project and this is my first time using VBA
Edit:
I realized that doing the following might work
exWb.Application.EnableEvents = False
However because I need to put this before the "Set" for it to stop the form from opening, it doesnt work (as the object is not set at the point the line is run).

Answer 1

You can disable Excel events with objExcel.EnableEvents = False before opening the workbook and reactivate them afterwards with objExcel.EnableEvents = True.
And as #Siddarth Rout told in comments, you can show your UserForm in Modeless mode with frmOpen.Show vbmodeless to avoid blocking other code execution. See MSDN remarks about this : https://msdn.microsoft.com/en-us/library/office/gg251819.aspx
So your code will look like this :
Private Sub cmdAutomatic_Click()
Dim objExcel As New Excel.Application
Dim exWb As Excel.Workbook
Dim selectID As String
objExcel.EnableEvents = False
Set exWb =objExcel.Workbooks.Open("C:\ Path")
exWb.Close
objExcel.EnableEvents = True
''Data is written into the document here
Set exWb = Nothing
Unload Me
End Sub
