Creating simple object
Posted on 2000-03-30
HI all, I am trying to learn object oriented techniques in vb. I know the
question i am asking is probably very easy one but neverthe less i need help
with it. Let's say i want to design a method in my class that will do validations.
Say i want to see if the textboxes are all field. So i create a isComplete()
method. So in my form i then call this method and pass parameters to it.
ex. Set oCheck = New iCheck
but right after i call oCheck method i need to call another method let's
call it Register. But if isComplete returns that not all textboxes have been
filled i don't want to call Register method. How do i do that ?
I was suggested to do this. But i did't understood what the property Varified meant. Here is what the person suggested.
4 options (not mutually exclusive) out of probably many, many more:
1. make "IsComplete" a function and return a boolean for success:
If oCheck.IsComplete(text1.text,text2.text) Then
2. Add a "Verified" property to the object:
Call oCheck.IsComplete(Text1.Text,Text2.Text) If oCheck.Verified Then
3. Raise an error in the IsComplete routine if it fails and use Error
Trapping in the client
4. Raise an event in the IsComplete routine and set a flag in the client
I would appriciate any feedback
