Help Needed creating a Popup in the Icon Tray

I have created an application that runs in the Icon Tray, that when clicked, a Menu Appears with applications that I wish to Run.

This works well.

I now want to modify the Application (Version 2), where my application reads the Following INI File.

[App1]
AppDesc='Run App1'
AppPath='D:\My Apps\App1.exe'

[App2]
AppDesc='Run App2'
AppPath='D:\My Projects\Projects\App2.exe'

[App3]
AppDesc='Run App3'
AppPath='D:\My Projects\App3\App3.exe'

[App4]
AppDesc='Run App4'
AppPath='D:\My Projects\App4\App4.exe'


I want the Application to then Create a Menu Item for each AppDesc, and then allows the user to EXECUTE the application contained within the AppPath.


I basically have the following code, my previous application had 4 procedures
    MyPopupHandler1(Sender: TObject);
    MyPopupHandler2(Sender: TObject);
    MyPopupHandler3(Sender: TObject);
    MyPopupHandler4(Sender: TObject);
Which were hardcoded with the Application Path and EXE Name and all worked well

type
  TForm1 = class(TForm)
    abcTrayIcon1: TabcTrayIcon;
    abcSingle: TabcSingleInstance;
    mPopup: TPopupMenu;
    procedure FormCreate(Sender: TObject);
    procedure MyPopupHandler(Sender: TObject);
    procedure ExitApp(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
var
  MyItem: array[0..4] of TMenuItem;
  i: Integer;
  SystemIni: TIniFile;
  secList: TStrings;
begin
  secList:=TStringList.Create;

  SystemIni := TIniFile.Create('C:\data\Popup.ini');
  SystemIni.ReadSections(secList);

  for I := 0 to secList.Count - 1 do begin    // Iterate
      MyItem[i] := TMenuItem.Create(Self);
      MyItem[i].Caption := SystemIni.ReadString(secList.Strings[I],'AppDesc','-');
      appPath := SystemIni.ReadString(secList.Strings[I],'AppPath','-');
      MyItem[i].OnClick := MyPopupHandler;
      mPopup.Items.Add(MyItem[i]);
  end;    // for
  MyItem[i+1] := TMenuItem.Create(Self);
  MyItem[i+1].Caption := 'Exit';
  MyItem[i+1].OnClick := ExitApp;
  mPopup.Items.Add(MyItem[i+1]);
end;

procedure TForm1.MyPopupHandler(Sender: TObject);
begin
  WinExec(appPath,SW_SHOW);    // application Path and EXE here
end;

procedure TForm1.ExitApp(Sender: TObject);
begin
  Application.Terminate;
end;


Any help would be greatly appreciated

Thanks

OK, here is what i came up with:

I added a main section with a count to my inifile


[MAIN]
COUNT= 3
[App1]
AppDesc='Preso'
AppPath='C:\Program Files\Borland\Delphi7\Projects\Preso\Preso.exe'

[App2]
AppDesc='GCM'
AppPath='C:\Program Files\Borland\Delphi7\Projects\GCM\GCM.exe'

[App3]
AppDesc='Poker'
AppPath='C:\Program Files\Borland\Delphi7\Projects\Poker\Project1'


you will need this to execute the applications

uses
  ShellAPI;


//this is the OnClick event you will assign to each menuitem


procedure TForm1.MyCLick(Sender: TObject);
var
 IFile: TIniFile;
 IApp: String;
begin
 //open ini file
 IFile:= TIniFile.Create(ChangeFileExt(Application.ExeName,'.ini'));
//get menu item path
 IApp:= IFile.ReadString('APP' + IntToStr(TMenuItem(Sender).MenuIndex),'AppPath','');
//execute menu item
 ShellExecute(Handle, 'open', PChar(IApp), nil, nil, SW_SHOWNORMAL);
end;

//create menu items on form startup

procedure TForm1.FormActivate(Sender: TObject);
var
 IFile: TIniFile;
 MItem : TMenuItem;
 I, Count: Integer;
 IName: String;
begin
//open inifile
 IFile:= TIniFile.Create(ChangeFileExt(Application.ExeName,'.ini'));
//get count
 Count:= IFile.ReadInteger('MAIN','COUNT',0);
 for I:= 1 to Count do
 begin
 //get app name
  IName:= IFile.ReadString('APP' + IntToStr(I),'AppDesc','');
  MItem := TMenuItem.Create(PopupMenu1);
  MItem.Caption:= IName;
  MItem.OnClick := MyCLick;
  PopupMenu1.Items.Add(MItem);
 end;
end;

end.

Hope this helps

hello pjelias, I would use the Hint property of the menu Item to store the App Path for each Memu Item-
you can try this code for a button click


procedure TForm1.MyPopupHandler(Sender: TObject);
begin
if (Sender as TMenuItem).Hint <> '-' then
  WinExec(PChar((Sender as TMenuItem).Hint),SW_SHOW);
// by casting the Sender to a menu Item you can just have ONE procedure for ALL of your memu Itens
end;

procedure TForm1.sbut_ReadIniClick(Sender: TObject);
var
SystemIni: TIniFile;
secList: TStringList;
MyItem: TMenuItem;
appPath: String;
i: Integer;
begin
SystemIni := TIniFile.Create('E:\Popup.ini');
secList:=TStringList.Create;
SystemIni.ReadSections(secList);
for i := 0 to secList.Count - 1 do
  begin
  MyItem := TMenuItem.Create(PopUpMenu1); //  I use only ONE menu Item variable for all of the items
  MyItem.Caption := SystemIni.ReadString(secList.Strings[i],'AppDesc','Run '+secList.Strings[i]);
  MyItem.Hint := SystemIni.ReadString(secList.Strings[i],'AppPath','-');
  MyItem.OnClick := MyPopupHandler; // all of the Items will use the same click procedure
  PopUpMenu1.Items.Add(MyItem);
  end;
  MyItem := TMenuItem.Create(PopUpMenu1);
  MyItem.Caption := 'Exit';
  MyItem.OnClick := ExitApp;
  PopUpMenu1.Items.Add(MyItem);
PopupMenu1.Popup(300,300);
end;

FreeAndNil(SystemIni);
FreeAndNil(secList);

and the
appPath: String;    is not used

Shane,

I probably could have split the points, I used Slick182's because the code looked a bit "cleaner" ie. didn't need to modify INI - Add Count, PopUpHandler (MyClick) Used 1 line instead of 3 etc.....

My apologies

shaneholmes, I did my code compleatly independently of anything you have ever posted here, the creative part of my code is using the hint for the extra string for appPath, where in your code is that? And on your click event, why do you do something as ineficient as reading the ini file a second time?
