How do i save statusbar settings to the registry etc...

How do i save statusbar settings to the registry, I want to have a View| Status Bar, and have it display and hide the status bar, but also save the settings to the registry at the same time. So when i load my program the statusbar will be displayed or not displayed. also have the statusbar menu item check when the statusbar is displayed and not checked when it is hidden on startup. Code Examples Please Thank's Hyper66.

The easiest way is to use TRegIniFile. Add the following part to your forms implementation part and do the following:

1 - Declare the following in your forms public part
procedure WriteRegistry;
procedure ReadRegistry;
2 - on your menu click paste the code I supplied
3 - Test the result

The following creates a key under HKEY_CURENT_USER\Software\hyperProgs\hyper66.
You can add as many properties as you want with this method


const
  SECTION = 'hyper66';
var
  FIniFile : TRegIniFile;

procedure tform1.FormCreate(Sender: TObject);
begin
  FIniFile := TRegIniFile.Create('Software\hyperProgs');
  ReadRegistry;
end;

procedure tform1.WriteRegistry;
begin
  FIniFile.WriteBool(SECTION, 'BooleanTest', MyMenu1.Checked);
end;

procedure tform1.ReadRegistry;
begin
  MyMenu1.Checked := FIniFile.ReadBool(SECTION, 'BooleanTest', False);
end;

procedure TForm1.MyMenu1Click(Sender: TObject);
begin
  MyMenu1.Checked := not MyMenu1.Checked;
  WriteRegistry;
  //hide or show you status bar here
end;

regards, igor

I followed the example above but all the code does is just add a Zero to registry, How can i get it to display or hide the statubar by reading from the reg, I can't get that part to work.
This is what i have.

Unit Unit1;

Procedure TForm1.FormCreate(Sender: TObject);
Begin
 RegIni := TRegIniFile.Create('Software\HyperProgs');
 ReadRegistry;
End;

Procedure TForm1.WriteRegistry;
Begin
 RegIni.WriteBool(Section,'BooleanTest',StatusBar1.Checked);
End;

Procedure TForm1.ReadRegistry;
Begin
 StatusBar1.Checked := RegIni.ReadBool(Section,'BooleanTest',False);
End;

procedure TForm1.Statusbar1Click(Sender: TObject);
Begin
 StatusBar.Visible := Not StatusBar.Visible;
 WriteRegistry;
  If StatusBar.Visible Then
   StatusBar.Visible := True
   Else

My friend,
the good programing practice tells us to syncronize the actions of linked controls. What I mean is to think carefully about WHO causes WHAT before coding. In our example

StatusBar1 menu CAUSES StatusBar to be visible or not
So, the our original even for synchronization should be CHANGE of StatusBar1.Checked. We'better do the following:(the other parts are unchanged)

Procedure TForm1.WriteRegistry;
Begin
  RegIni.WriteBool(Section,'BooleanTest',StatusBar1.Checked);
End;

Procedure TForm1.ReadRegistry;
Begin
 StatusBar1.Checked := RegIni.ReadBool(Section,'BooleanTest',False);
 StatusBar.Visible := StatusBar1.Checked;
End;

procedure TForm1.Statusbar1Click(Sender: TObject);
Begin
 StatusBar1.Checked := not StatusBar1.Checked;
 StatusBar.Visible := StatusBar1.Checked;  
 WriteRegistry;
End;
