[SOLVED] The name xyz does not exist in the current context. I know why it happens but can't fix.

I have a simple form with a textbox.

When the user hits '1' the textbox should display '1'.

But let's look inside the program:

Normally, I could do something like: setText("1");

But since I'm trying to incorporate OOP principles, I should be doing something more like: ghostClass.setText("1");

setText() basically does this -> theTextBox.Text = textToSet;

Yes, without OOP, that'd work. But with OOP, the ghostClass shouldn't even know theTextBox exists right? So it can't do this -> theTextBox.Text = textToSet; <- because this -> The name 'theTextBox' does not exist in the current context. <- would happen.

I was thinking that instead of -> setText("1") <- I should be using somethign clsoer to -> theTextBox.Text = ghostClass.setText("1"); <- but when I look at that I feel it should just say -> theTextBox.Text = "1"; <- and that I have unnecssary complicated the code--I mean why would I sent the text to set only to have it returned? -_-

I could eleborate on the issue even more by introducing another method -> ghostClass.clearTextBox(); As before I can't use -> theTextBox.Text = string.Empty <- because of the existence issue.

Please help.

So your basicaly hooking user's keyboard and recording it?

Of course not.

If pressing '1' is giving you that idea then think of it as clicking the '1' button in the GUI app.

let me get this straight, you are using a console application to write text to a textbox in a GUI application?
