You can do someting, like this in the load

MessageBox.Show(((Form1)this.Owner).textBox1.Text);

But now, I ask, why you need to do someting like this

Hi,

You can change the declaration of your textbox from private into public. To do this, click the control in design vew and in the properties window search for the Modifier property and change it to public...

Hi,

Sorry, I haven't read all of your post (i really must change this habbit). bistok's post is correct. But just to make it clearer, you should make your Form1 be the Owner of Form5 you can do this by setting the owner property of Form5 to your Form1. Confused well here's a code snippet that does that:

// On your Form1, upon displaying form5
private void button1_Click(object sender, System.EventArgs e) {
Form5 frm5 = new Form5();
frm5.Owner = this;
}

// just like what bistok posted you can access your form like this.
private void Form5_Load(object sender, System.EventArgs e)
{
Form1 frm1 = (Form1) this.Owner;
string name = frm1.textBox1.Text;
MessageBox..Show(name);
}

That don't work because this: Form1 frm1 = new Form1(); Creates a new instance of the Form1, and that instance don't have text in TextBox1.

Hi,

No, this would just let you access the control on another form. This routine would give you rights to change the other forms button text to something that you want. It gives you control over the controls on the other form.

BTW, are you an ilocano as in from ilocos, phil
