[RESOLVED] [2005] Textbox help

Hello everyone,

Ok so I am trying out this code; link but I stumbled upon an error..

I want to put the text of "textbox1" (or the vdata string) into a textbox
on another form (form2). Now, this is ezmode;

Code:

---

form2.textbox.text = textbox1.text

---

Ofcourse this isnt working, can anyone tell me why ?
Is it because it runs on another thread ? :lol:

did you try

form2.textbox.text = form1.textbox1.text

I tried

Code:

---

form2.textbox.text = me.textbox1.text

---

,
isnt working either :(

Form2 refers to the default instance of Form2. Unless that is the instance you are displaying to the user, you wont see anything happen.

So you are obviously creating an instance of Form2 somewhere, that instance is unique in itself and if you wish to interact with that instance you'd do best to keep a reference to that form.

Cant your try putting it in a module, public varible?

so you got a module with like?
public textbox as string

then public = form2.textbox.text

then on form one have me.textbox.text = public?

or something along them lines?

Or am i just chatting bs?

Sorry if it aint right im new and just an idea?

Ben

As Atheist said you need an instance of Form 2 availble, it does not have to be visible though.

vb Code:

Form2.Show()
Form2.Hide()

Thanks for all the reply's !

I have an instance of the form, its loaded, and visible right next form1..

I am not receiving any error messages ;x..
This code;

Code:

---

form2.textbox.text = form1.textbox1.text

---

Does nothing for me.. Its very strange

That is because you are accessing the wrong instance of Form2. You are, in this code, modifying the default instance of Form2, which is obviously not the same instance as you are displaying in the screen.
Show us where you create and show Form2.

did you copy this code straight from your project? If you have a spotted an error.

Code:

---

form2.textbox.text = form1.textbox1.text

---

Take a look at it.

Code:

---

form2.textbox.text

---

and

Code:

---

form1.textbox1.text

---

do you mean textbox? or on form2 is it called textbox1?

I originally thought that this was an error, because i though textbox is a preserved name, i think i may be wrong, but anyway you can check to make sure the names match.

How are you showing Form2?

There's a difference between the following two methods which I (and Atheist too by the looks of it) think is your problem.

One method is showing the default instance of Form2, which you can then reference simply by "Form2. ...":

Code:

---

Form2.Show()

---

The other method is creating a new instance of Form2 and showing that, which you can NOT reference by simply "Form2. ...":

Code:

---

Dim newForm As New Form2
newForm.Show()

---

In this second method, you should use "newForm.Textbox..." to reference it!

If you don't already have the answer....

in form 2 onload use the following code

vb Code:

textbox1.text = form1.textbox1.text

OK then so what is the difference? They all accomplish the same thing.

Code:

---

Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Me.TextBox1.Text = "So what is the difference on how this works?"
    End Sub
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Form2.Show()
        ' passing the values to form two
        Form2.TextBox1.Text = Me.TextBox1.Text.Trim
        Form2.TextBox2.Text = Me.TextBox1.Text.Trim
        Me.Hide()
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim formTwo As New Form2
        formTwo.Show()
        ' passing the values to form two
        formTwo.TextBox1.Text = Me.TextBox1.Text.Trim
        formTwo.TextBox2.Text = Me.TextBox1.Text.Trim
        Me.Hide()
    End Sub

    Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Form3.Show()
        ' passing the value to Form3
        Form3.TextBox2.Text = Me.TextBox1.Text.Trim
        Me.Hide()
    End Sub

    Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
        Me.Close()
    End Sub
End Class

Option Explicit On

Public Class Form2
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Form1.Show()
        Me.Close()
    End Sub
End Class


Option Explicit On

Public Class Form3
    Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ' Getting the values from Form1
        Me.TextBox1.Text = Form1.TextBox1.Text.Trim
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Form1.Show()
        Me.Close()
    End Sub
End Class

Hi,

You can try this:

vb.net Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim Form2 As New Form2
        Form2.Label1.Text = TextBox1.Text
        Form2.Show()
    End Sub

Wkr,

sparrow1

Thanks again for all the reply's everyone!..

Ok I have tried everything, but its not putting any text in the
textbox.

I think its because part of the code is running on another thread.
When I put a simple "form2.textbox.text = "hello"" into the form_load
event. It works, but when I put that code into the "Private Sub UDPArrival"
the code doesnt work...

Anyone of you guys/girls has a Linksys router :) ?

Ok.. I fixxed it, and my code is now working as it should be.

I restarted my computer, did a rebuild of my code. And it was working!
Did not changed any code, very strange...


Thanks for all the help !
