Question

I’ve some pocket pc app and i’m having a serious problem with it described here: https://stackoverflow.com/questions/472598 . While looking for a solution i tried some actually quite stupid code in Main():

[MTAThread]         static void Main()         {             Application.Run(new Tasks());             Application.Exit();         } 

and set breakpoint on exit. if i just run the application and then close the window the breakpoint is reached. if i run the application and then open another window:

private void questButton_Click(object sender, EventArgs e)         {             QuestionnairesWindow questWindow = new QuestionnairesWindow();             questWindow.Show();             this.Hide(); } 

and then get back from it to initial window:

private void backButton_Click(object sender, EventArgs e)         {             Tasks tasksWindow = new Tasks();             tasksWindow.Show();             this.Close();         } 

and close the initial one the same way as the first time, the Apllication.exit() code is never reached and i have an impression that the application isn’t really closed ( i can’t open it again). sorry if the description is complicated

edit: the question is – any ideas why is it behaving differently?

Answer 1

new Tasks() in Main() is not the same object with Tasks tasksWindow = new Tasks();

You got 2 objects of Tasks, so closing second, first is still present and never dies. You need to pass to QuestionnairesWindow the reference of current Tasks.

You can do that with additional QuestionnairesWindow constructor:

private Tasks tasks;  public QuestionnairesWindow(Tasks t) {   this.tasks = t; } 

using:

new QuestionnairesWindow(this).Show(); // where this = current `Tasks` created in `Main`
