Application Security Testing: An Integral Part of DevOps

Use Object Substitution

Use object substitution to substitute a simple name with an extended object reference. Each "." in the syntax represents an OLE lookup. Better performance is achieved the fewer times lookups need to be performed. For example:
 For i = 1 to 10
	txt(i) = myApp.TimeSheet.Employee.Name
Next I
Performs better if rewritten using substitution:
 Dim emp as New Employee

' Create the substitution object variable
Set emp = myApp.TimeSheet.Employee

For i = 1 to 10
	txt(i) = emp.Name
Next I
