Accessing Form Controls via a sub

[SDillon]

Does anyone know how to access a windows form control e.g. a text box from a sub procedure within a module. For example, I would like to call a sub in the form load event to prefill a text box or a listbox. However, I cannot access the active form's controls.

Use Form Activate event. Controls may not be available when the load event fires.

Passing the form control to the sub works as others had suggested in other posts.

'Form 1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Call mySub(Me.TextBox1)

End Sub



'Module 1
Module Module1
Public Sub mySub(ByRef mytextBox As TextBox)
mytextBox.Text = "test"

End Sub
End Module

I believe controls are accesible after the Form.New is done, so it should be available in Form_Load (I THINK!)

I'm not sure what exactly you want to do... you say you want to access the control through a module? or you want to access it in Form_Load?!

umm and if you want to prefill some controls when you load the form, you could just modify the New constructor to receive the controls....
