Hi,
In my app I have a group of checkboxes which represent different settings. I want to be able to load and save these settings into the program, and that works just fine. However I'm having trouble updating the checkboxes to show the settings. If I load the settings, only the first checkbox is updated. However I have a defaultsettings button, and when I click it the checkboxes are updated one at a time (I need to click the button 7 times to get the checkboxes to update).
Here is my code:

//Default settings constructor inside Settings class
public Settings()
         {
             acon = true;
             addnew = true;
             defNPC = "";
             shoscr = true;
             copscr = false;
             savscr = false;
             defpath = "C:\\Program Files\\Gothic\\_Work\\Scripts";
         }

//my update code
private void button11_Click(object sender, EventArgs e)
        {
            AppSet = new Settings();
            log.wtl("Domyślne ustawienia załadowane");
            SetUI();
        }

private void SetUI()
        {
            checkBox1.Checked = AppSet.acon;
            checkBox2.Checked = AppSet.addnew;
            textBox1.Text = AppSet.defNPC;
            checkBox3.Checked = AppSet.shoscr;
            checkBox4.Checked = AppSet.copscr;
            checkBox5.Checked = AppSet.savscr;
            textBox2.Text = AppSet.defpath;
            log.wtl("Interfejs zaktualizowany");
        }

Can anyone help me with this? Do I have to redraw the form or something? BTW AppSet is the global settings object.

Nothing obvious standing out that I can see. What happens if you comment out that log.wtl("...") statement? Also, if there are other locations in the code where these Settings members or CheckBox.Checked states get modified, I would watch out for that too.

as ddoubled said, the code looks sound.
If you are still having problems you can attach your project here or post the full code so we can check if something is being changed elsewhere :)

OK, I've attached my project. Sorry the program is in Polish, but here's what the button labels mean:
Zapisz Ustawienia - Save Settings
Domyślne Ustawienia - Default Settings

Thanks

Anybody?

Sorry for triple post, but I think I've just realized what is causing the problem.
With all of the checkboxes, they have updatesettings set as their handler for OnCheckChange, and that changes the settings except the one changed to blank again.
Is there anyway of changing the checboxes' state without calling the event? Or is there a more elegant solution?


Thanks

OK, I've attached my project. Sorry the program is in Polish, but here's what the button labels mean:
Zapisz Ustawienia - Save Settings
Domyślne Ustawienia - Default Settings

Thanks

OK, I downloaded and have gone back to read the thread. You said the Default button (AKA defaultsettings), is something different than what I see. Is this the default settings button you keep having to click: "Załaduj domyślne"?

Yea, I just stepped through the loading of the form, and you are changing the appsettings to be the current checkbox states every time a checkbox state is changed, so the first assignment in SetUI():

private void SetUI()
        {
            checkBox1.Checked = AppSet.acon;
            checkBox2.Checked = AppSet.addnew;
            textBox1.Text = AppSet.defNPC;
            checkBox3.Checked = AppSet.shoscr;
            checkBox4.Checked = AppSet.copscr;
            checkBox5.Checked = AppSet.savscr;
            textBox2.Text = AppSet.defpath;
            log.wtl("Interfejs zaktualizowany");
        }

causes all the appsetting states to be changed to the current checkbox's states because each checkbox is tied to the CheckChanged event, which is call the UpdateSettings method....

Here is one fix:

bool bInSetUI = false;
        private void SetUI()
        {
            bInSetUI = true; // suspend CheckChanged event

            checkBox1.Checked = AppSet.acon;
            checkBox2.Checked = AppSet.addnew;
            textBox1.Text = AppSet.defNPC;
            checkBox3.Checked = AppSet.shoscr;
            checkBox4.Checked = AppSet.copscr;
            checkBox5.Checked = AppSet.savscr;
            textBox2.Text = AppSet.defpath;
            log.wtl("Interfejs zaktualizowany");

            bInSetUI = false; // resume CheckChanged event...
        }

        private void UpdateSettings(object sender, EventArgs e)
        {
            if (!bInSetUI)
            {
                AppSet.acon = checkBox1.Checked;
                AppSet.addnew = checkBox2.Checked;
                AppSet.defNPC = textBox1.Text;
                AppSet.shoscr = checkBox3.Checked;
                AppSet.copscr = checkBox4.Checked;
                AppSet.savscr = checkBox5.Checked;
                AppSet.defpath = textBox2.Text;
                log.wtl("Ustawienia zaktualizowane");
            }
        }
commented: That was going to be my suggestion until you stole my thoughts :X +6

You should refactor

log.wtl("Interfejs zaktualizowany");

to:

log.wt[B]f[/B]("Interfejs zaktualizowany");

Its more fun :)

commented: That's great! hahaha +2

Yea, I did what DdoubleD said straight after i posted the last post :P
except instead of

#
bInSetUI = true; // suspend CheckChanged event
#
 
#
checkBox1.Checked = AppSet.acon;
#
checkBox2.Checked = AppSet.addnew;
#
textBox1.Text = AppSet.defNPC;
#
checkBox3.Checked = AppSet.shoscr;
#
checkBox4.Checked = AppSet.copscr;
#
checkBox5.Checked = AppSet.savscr;
#
textBox2.Text = AppSet.defpath;
#
log.wtl("Interfejs zaktualizowany");
#
 
#
bInSetUI = false; // resume CheckChanged event...

mine was more like

#
bInSetUI = true; // suspend CheckChanged event
#
 
#
checkBox1.Checked = AppSet.acon;
#
checkBox2.Checked = AppSet.addnew;
#
textBox1.Text = AppSet.defNPC;
#
checkBox3.Checked = AppSet.shoscr;
#
checkBox4.Checked = AppSet.copscr;
#
checkBox5.Checked = AppSet.savscr;
bInSetUI = false; // resume CheckChanged event...
textBox2.Text = AppSet.defpath;
#
log.wtl("Interfejs zaktualizowany");
#
 
#

So the interface would get updated at the last textbox.
all the wtl does is write to a log, which is on a separate form.
Thanks anyway
