Classes and propertys

JPOhlman · August 16th, 2006, 09:13 AM

Hi, I am new to visual basic, and to this forum.
I have a question:
I created a class (called classPerson) , and gave it certain propertys,
then I created a property of my main forum called Person as ClassPerson
under the set part of the code I set varoius text boxes to the propertys of the class:
Example:

Code:

textboxSam.text = person.Name
textboxAddress = persen.Address

However when I Change the person.address property, the text box doesent change.

Do I need to specify it so it changes each time I change the person.address property or what?

The contents in the text box only are assessed when the control is created.
To get the textbox to reflect the changes to the source of its contents it will need to be refreshed.

You could add a collection to the class which holds a list of everything that uses the instance of the class, and when that instance has a property changed, it would go through its list of âclients,â sending them all notification of the change.

Here I have another Problem:

I created a user control called Personal details,
Then in the code for the button (called new person) I added this (among other things):

Code:

ObjPersonalDetails = New PersonalDetails

Later I asked the computer to:

Code:

    Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        If ObjPersonalDetails IsNot Nothing Then
            MsgBox(ObjPersonalDetails.TextBoxAddress.Text)
        End If
    End Sub

when I clicked the apropriat button:
the mesage box stated "11432 FM 957"
However In the code of personaldetails I included this:

Code:

    
Private Sub TextBoxAddress_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TextBoxAddress.MouseClick
        MsgBox(TextBoxAddress.Text)


    End Sub

When I clicked button1 msgbox: '11432 FM 957"
When I cliked on TextBoxAddress msgBox: ''

Does anyone know what is going on?
