Writing to TextBox from Seperate Class

[JP]

I'm sure this is a simple question and I'm overlooking the obvious. But, I
have two seperate classes (in seperate files) under the same namespace. I
am calling a method in one class that contains
public System.Windows. Forms.TextBox textBox1;

When I try to write to this textbox it never publishes anything. If I call
the same method from inside the same class it does. How can I publish to
this textbox from an external class. Simple example would be:

FILE: classone.cs

namespace DemoApp

{

public class classone : System.Windows. Forms.Form

{

public System.Windows. Forms.TextBox textBox1;

private System.Componen tModel.Containe r components = null;

public classone()

{

InitializeCompo nent();

}

private void InitializeCompo nent()

{

this.textBox1 = new System.Windows. Forms.TextBox() ;

((System.Compon entModel.ISuppo rtInitialize)(t his.timer1)).Be ginInit();

//

// textBox1

//

this.textBox1.L ocation = new System.Drawing. Point(0, 32);

this.textBox1.M ultiline = true;

this.textBox1.N ame = "textBox1";

this.textBox1.R eadOnly = true;

this.textBox1.S crollBars = System.Windows. Forms.ScrollBar s.Both;

this.textBox1.S ize = new System.Drawing. Size(568, 344);

this.textBox1.T abIndex = 4;

this.textBox1.T ext = "textBox1";

//

// classone

//

this.AutoScaleB aseSize = new System.Drawing. Size(5, 13);

this.ClientSize = new System.Drawing. Size(568, 373);

this.Controls.A dd(this.textBox 1);

this.Load += new System.EventHan dler(this.Form1 _Load);

((System.Compon entModel.ISuppo rtInitialize)(t his.timer1)).En dInit();

this.ResumeLayo ut(false);

}

public void addstatus(strin g status)

{

MessageBox.Show (status);

this.textBox1.A ppendText("HI") ;

this.textBox1.A ppendText(statu s + "\r\n\r\n") ;
}

}

}

FILE classtwo.cs

namespace WxAlert

{

public void addToreport(str ing rep, int debugDetail)

{

classone obj = new classone();

obj.addstatus(r ep);

}

}

When calling the addToreport method, everything compiles and runs - just
nothing gets written to the textbox window. Not even the "HI" - the
information does show correctly in the MessageBox.

In actuality this is the same NameSpace - that is a type-o. Thanks for the
assist.

You only create the classone form but you never show it. This is what
addToreport should look like addToreport should look like

public void addToreport(str ing rep, int debugDetail)
{
Form2 obj = new Form2();
obj.addstatus(r ep);
obj.Show();
}

Hmm.. Tried that and it just opened a lot of new windows without any change
to the textbox.

What the addToreport method is intending to do is send a string to the other
class which will then print that string in the textbox. I am using this for
reporting. so each time I call that method I want a string to be added to
the text box. Works perfectly if all my methods are in the class that
creates the form, but if I move things to a seperate class I can't seem to
create the same behavior.

Ok, add this to your main form where the text box is

If let's say your main form class is called Form1 then:

public static Form1 MainForm = null;

Then on your form initialization set it to itself that way a reference to
your form is maintained. In your form you can setup some accessor
attributes like this:

public string ValueForTextBox
{
set
{
TextBox1.Text = value;
}
get
{
return TextBox1.Text;
}
}

on your other classes, if they are in the same namespace you can use
something like:

Form1.MainForm. ValueForTextBox = somevalue;
Try it and see if it will help you.

Ok - think we're getting closer, so now I get an error:

'System.Windows .Forms.Control. text' is inaccessible due to its protection
level

in:

set

{

this.textBox1.t ext += value;

}
