Hi Hector,

Since every form is a class it's not directly possible to access one form
from another. The solution is to make a public static property in the form
(class) you want to access. This property contains a reference to the
instance of that form. An example of the property is shown below, the
example is using a form called Form1 which is the main form for the
application:

//The property, added to Form1
private static Form1 m_mainform;
public static Form1 MAINFORM
{
get { return m_mainform; }
set { m_mainform = value; }
}

Example for using this property to store the main form (form1) in:

//Standard main procedure of Form1
static void Main()
{
Form1 frm = new Form1 (); //Create a new instance of the form Form1
Form1.MAINFORM = frm; //Store this instance in the public static
property
Application.Run(frm); //Show the form
}

Now you can use the following line of code in every other form:

Form1.MAINFORM.Label1.text = "testing";

Don't forget to set the control you want to access to public instead of the
default private.

Hope this helps.
