The timer is assigned to a form and I’d like to Enable it at a specific location,but from another class.I don’t want to make it public

This is the code I use to access memo

    public string TextValue     {         set         {             if (this.Memo.InvokeRequired)             {                 this.Invoke((MethodInvoker)delegate                 {                     this.Memo.Text += value + '\n';                 });             }             else             {                 this.Memo.Text += value + '\n';             }         }     }      public static void addtxt(string txt)     {         var form = Form.ActiveForm as Form1;         if(form != null)             form.TextValue = txt;     } 

Answer 1

How would you like to enable the timer ? What action is undertaken in order to enable it ?

Is it possible to add an event to the class from which you want to enable the timer, and, on the form which contains the timer, subscribe to that event ? In the event-handler for that event, you can then enable the timer.

When the other class raises the event, the eventhandler will enable the timer.

public class SomeOtherClassThatDoesStuff {    public event EventHandler SomethingHappened;     public void DoStuff()    {       ...       if( SomethingHappened != null )          SomethingHappened;       ...    } }  public class Form1 {      private void Button1_Click(object sender, EventArgs e )     {        SomeOtherClassThatDoesStuff o = new SomeOtherClassThatDoesStuff();       o.SomethingHappened += new EventHandler(EnableTimer);        o.DoStuff();     }      private void EnableTimer(object sender, EventArgs e )     {        myTimer.Enabled = true;     } } 

Something like this. (I haven’t tested, nor did I even compile it, but I think you’ll catch the drift 🙂 ).
