Hello people,

I need to do this:
I have Form1 having textbox1. I want to display text entered into textbox1 into Label1 of Form2.

Suggestions Welcomed.

Define a property in Form2 that will hold that string, then assign to it and refresh()/invalidate() the control in Form2 whenever you want (ex. in the validated event of the textbox in Form1). For example, in Form2:

public string MyText {
    get { return textBox1.Text; }
    set {
        textBox1.Text = value;
        textBox1.Invalidate();
    }
}

And in Form1 (assuming a Form2 object has been created):

private void textBox1_Validated(object sender, EventArgs e)
{
    _form2.MyText = textBox1.Text;
}

Edit: My bad, I thought this was the C# forum. But the solution is identical, just use VB.NET instead of C#. ;)

how are you displaying form2? I do it with a button click in form1. So after creating an instance of form2 you just assign the text from form1.textox1.text to form2.label1.text

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim fm2 As Form2 = New Form2
        fm2.label1.Text = Me.textbox1.Text
        fm2.ShowDialog()
    End Sub

Only if the control is explicitly made public in Form2. By default new controls added through the designer are private (as they should be!), and in a code review I'd question making them public.

I didn't change anything like that. In fact I made no code changes at all to Form2. Here's the application declarations, all code generated by vb.net

    Private Sub InitializeComponent()
        Me.Label1 = New System.Windows.Forms.Label()
        Me.SuspendLayout()
        '
        'Label1
        '
        Me.Label1.AutoSize = True
        Me.Label1.Location = New System.Drawing.Point(112, 94)
        Me.Label1.Name = "Label1"
        Me.Label1.Size = New System.Drawing.Size(39, 13)
        Me.Label1.TabIndex = 0
        Me.Label1.Text = "Label1"
        '
        'Form2
        '
        Me.AutoScaleDimensions = New System.Drawing.SizeF(6.0!, 13.0!)
        Me.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font
        Me.ClientSize = New System.Drawing.Size(284, 262)
        Me.Controls.Add(Me.Label1)
        Me.Name = "Form2"
        Me.Text = "Form2"
        Me.ResumeLayout(False)
        Me.PerformLayout()

    End Sub

I'm not looking to jump into the fray; just providing some information.

For C# the default control access modifier is "private", for VB the default access modifier is "Friend" (internal).

In your Form2

label1.Text = Form1.textbox1.Text

[malshan.sandakelum]

use Modules...

[azareth]

create a variable that will hold the text in texbox1 in Form1
Dim x as String = TextBox1.Text

then on Form2 you can import
Imports ProjectName.Form1

with that you can
Label1.Text = Form2.x

or simply
Label1.Text = x
though i always include the form name as to not get confused ..

well i'm not particularly sure with the Import thing but that's what i learned from a certain site, or perhaps its not actually needed, anyways its not that hard so you can do it :) plus you can always use modules when you have functions that are used repetitively or to maintain the orderliness of your program.good luck
