. Net CF program startup and exit sequence

We are trying to close someProgramFirst, click'X'Or'OK'To exit the program (some programs willFormOrMenuTo exit the Program),. Net cfProcessing'X'And'OK'Click'X'The program form is not displayed but is minimized, but the program is still running. Click'OK'CallThis. Close ();

However, many users get used to PC operations and think that they quit the program after clicking 'x. However, developers can still do some processing to click 'x' and exit the program completely.

Next, let's take a look at the program startup and exit examples to illustrate the program startup sequence and exit sequence!

Start and exit the program order code
Public Form1 ()
{
Initializecomponent ();
Showdebug ( " Form1 Constructor " );
}

//Mark the order of startup and exit
Private IntM_index= 0;

private void form1_load ( Object sender, eventargs e)
{< br> showdebug ( " form1_load " );
}

private void form1_closing ( Object sender, canceleventargs e)
{< br> showdebug ( " form1_closing " );
}

private void formshortclosed ( Object sender, eventargs e)
{< br> showdebug ( " form1_closed " );
}

private void form1_activated ( Object sender, eventargs e)
{< br> showdebug ( " form1_activated " );
}

private void formshortdeactivate ( Object sender, eventargs e)
{< br> showdebug ( " formatedeactivate " );
}

protected override void onload (eventargs E)
{< br> showdebug ( " onload " );
base . onload (E);
}

protected override void onclosing (canceleventargs E)
{< br> showdebug ( " onclosing " );
base . onclosing (E);
}

protected override void onclosed (eventargs E)
{< br> showdebug ( " onclosed " );
base . onclosed (E);
}

protected override void onactivated (eventargs E)
{< br> showdebug ( " onactivated " );
base . onactivated (E);
}

protected override void ondeactivate (eventargs E)
{< br> showdebug ( " ondeactivate " );
base . ondeactivate (E);
}

private void showdebug ( string funcname)
{< br> system. diagnostics. debug. writeline ( + m_index ). tostring () + " - " + funcname );
}< br>

Note:
Before explaining this, I 'd like to explain Form1_load And Onload Differences: In the base class Onload The function triggers an event call. Form1_load . If you rewrite Onload Function (not called Base. onload (E ); Define your own operations during program loading ).CodeIt will not be executed, that is Form1_load Will not be executed .
The same applies to other functions.

1. First, check the program startup sequence:

1-form1 Constructor 2-onload 3-form1_load 4-onactivated 5-form1_activated

We can know that the program starts according to the "Constructor-Load-activated.

2.Then click'X'Exit sequence after the number:

1-form1 Constructor 2-onload 3-form1_load 4-onactivated 5-form1_activated 6-ondeactivate 7-form1_deactivate

The exit order of clicking 'X' is "deactivate", but it does not enter onclosing or onclosed, then we can understand why the program does not exit after clicking 'x. So what should we do? It's very simple. Because the program enters deactivate after 'x', weCall this. Close () in ondeactivate or formatedeactivate to accessOnclosing and onclosed are in progress, and then some exit processing is done in onclosing and onclosed. That's it!

3. Click the exit sequence after 'OK '.

1-form1 constructor 2-onload 3-form1_load 4-onactivated 5 -form1_activated 6-onclosing 7-form1_closing 8-onclosed 9-form1_closed 10-ondeactivate 11-form1_deactivate

Well, after clicking 'OK', The onclosing and onclosed operations are more complicated than clicking 'x.
__________I believe that through the above instructions, coupled with your own single-step debugging, you have understood the program loading and exit mechanisms.OK, that's it!Good luck!
