Passing value to a Forms TextBox

How do I pass a value from a Public Sub in a class to a forms textbox.

I get 'Name Forms is not declared' with Forms!frmName!txtBoxName.

Is this an ASP.NET Textbox control? If so, just use the name of the
control, as in:

txtUser.Text = someValue

In the Public Sub in your class, you need a reference to the form concerned.
There are many ways of achieving this but one way is:

Dim _f As Form = My.Application.OpenForms("frmName")

An object of type Form does not, of course know anything about txtBoxName,
so you need to cast the reference to a variable of type frmName:

Dim _f As frmName = CType(My.Application.OpenForms("frmName"), frmName)

Now that you have the reference, you can manipulate the TextBox directly:

_f.txtBoxName.text = "The quick brown fox ..."

There are a number of nuances to this approach but if the app is a basic
Windows Forms app then this approach should work just fine in most cases.

Here's another way of doing it:

- Start Windows App
- Add a button to form1
- Add a second form
- Add a textbox to form2

Open form2 in code view & add this code:

    Public Shadows Sub ShowDialog(ByVal s As String)
        TextBox1.Text = s
        MyBase.ShowDialog()
    End Sub

    Public Shadows Sub Show(ByVal s As String)
        TextBox1.Text = s
        MyBase.Show()
    End Sub

Double-click the button in form1 & add one of these snippets:

' Show modal:

        Dim frm As New Form2
        frm.ShowDialog("Hello, World!")
        frm.Dispose()

' Show form:

        Dim frm As New Form2
        frm.Show("Hello, World!")

I hope this helps,

Hi,

I'm guessing that form2 is discarded after the magic has worked. Usefull, I
have seen this example on another site but it's not quite what I need just
now. One for later in the project.

Regards

Terry
