Passing controls to functions

Does anyone know if :

1. You can pass controls through to functions and change their properties.
2. How to do it!

Cheers Guys...

O.K.

The simplist way of doing this is to have a parameter in you function that is of type OBJECT. Say you have a control on your form, such as TEXT1, and a function called ChangeText that you want to alter the text property of the control. This example calls the function in the Form_Load event.

Sub Form_Load()
dim boolResult as Boolean
boolResult = ChangeText(TEXT1)
end sub

Public Function ChangeText(TextControl as Object) as Boolean
TextControl.Text = "My New Text"
ChangeText = True
End Function

use TypeName to check of the Object passed is a TextBox
i.e.

if TypeName(Object)="TextBox" then
...
end if



td.

You can also specify the type as Control.

Code:

---

Sub Change(ctl As Control)
    If TypeOf ctl Is TextBox Then ctl = "HELLO"
End Sub

Cheers fellas that has got me sorted!
