Modules??

[mulliganmark]

I have created a form with 'x' of textboxes on it, that have mulitple validation rules. So i Thought that i will create a module to do the checking & validation.

 

But how do i link the textbox of the form to the module.

 

PS this is my first time at coding

Hi mulliganmark

 

in your Module you build a Function and return a string

see my Code sample

Public Function myTextBox()
       Dim _string As String
       _string = " Here comes a text"
       Return _string
   End Function

'------------------------------------------
This write in your Form1 Class
TextBox1.Text = Module1.myTextBox

I think that explained it wrong.

 

What i want to do is pass the textbox1 (form1) value to the module1.

It will then validated it by saying ie "Please note you have to enter a value"

 

I think another way is. That you have 3 textboxes on form1, these boxes perform a calculation ie box1 + box2 = box3. Therefore in the module it check to see if there is a value in box1 & box2 if not returnd and error message?

 

I hope this is better

You can create a function that returns a Boolean value to do

your validation. Return False if it isn't validated, and True if it's okay.

 

Public Function ValidateBox(txt As TextBox) As Boolean

' in here, check the value of txt.Text and if it is okay, then:
' Return True
'
' Otherwise, you want to:
' Return False

End Function

 

Then, in your form code, just pass the textbox to the sub, check

the Boolean value that is returned, and show a message if it's

false. You can create functions that accept more than one textbox

in the arguments, if you want.

Just a suggestion; If you want to have user-friendly error validation,

look in Tutor's Corner (or was it Code Library?) for divil's tutorial

about using the ErrorProvider component. It allows for non-intrusive,

yet effective error notification.
