Access Form Controls from other class

[sammurai]

Hi all:

I Have 2 controls in Form1 (TextBox1 and Button1).
TextBox1.Text = "111"

Then I have a class (myClass.vb) that inherits Form1
This class as a:

Sub ChangeText()
dim objForm1 as New Form1
objForm1.TextBox1.Text = "222"
End Text

When I click on Button1 i want to go to the ChangeText() in the other class and change TextBox1.Text

Function Button1_Click
dim objmyClass as New myClass
objmyClass.ChangeText()
End Function


But it doesn't work ..

How can I change TextBox1 properties or other Control properties that are in Form1.vb from a Function that is in myClass.vb?

Thanx in advance.
B.

You'd have to pass in the instance of the form you are using ot the instance of the control and probably ByRef.

See in this code:

Sub ChangeText()
dim objForm1 as New Form1
objForm1.TextBox1.Text = "222"
End Text

You are creating a whole new form and then changing the textbox in it. You need to work with the form that is already open. Try something like this:

Sub ChangeText(ByRef Sender as Object, e as System.EventArgs)
dim frm as Form1
frm=CType(Sender,Form1)
frm.TextBox1.Text = "222"
End Text

I'm not sure that is correct but it should be something along that line. And when you call it use this:

Function Command1_onclick
dim objmyClass as New myClass
objmyClass.ChangeText(Me,Nothing)
End Function
