find function word processor

[Alvo von Cossel I]

hi,

i am creating a word processor in c# and would like to know 2 things:

1. in my separate find form, how do i acess a richtextbox in my main form
(form1)?

2. i know the code to find stuff e.g.

richtextbox1.fi nd(searchtermsb ox.text);

but if you click the find button with this code at its onclick event, it
will only find the first time the text appears. what code do i need for a
button that finds all of the recurrances of the text e.g. a find next button?

There are several overloads of find. One uses the text only, one takes
an integer as the second argument, which is the position to start
searching from.

int pos = 0;

for ( int i=0; i<3; ++i )
pos = richtextbox1.fi nd( searchtermsbox. text, pos+1 );

for example, will find the 3rd occurrence.

Not unlike the source viewer you were making for your web browser, your best
bet would be to expose a property from the form containing the RichTextBox
that is accessible via the reference to the containing form from the calling
code.

You have two choices.

1) Make the richtextbox a public variable in form1:

public class Form1
{
public RichTextBox richtextbox1; // Change from private.
}

2) Make it a property of the form:

public class Form1
{
private RichTextBox richtextbox1;

public RichTextBox RichText // Or whatever you want to call it.
{
get { return richtextbox1; }
}
}

Then just use it from another form:

public class Form2 : Form
{
void function()
{
// Case 1: public variable
Form1.richtext1 .<whatever>
// Case 2: property
Form1.RichText. <whatever>
}
}
