If you type in "Staff" in the username and "warwickschool2013" in the username, the program takes you to the "teacher" side of the program where they can add in new users. unit LoginScreen; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls, jpeg, ExtCtrls; type TfrmLogin = class(TForm) lblWelcomeLogin: TLabel; edtPassword: TEdit; lblPassword: TLabel; btnLogin: TButton; btnClose: TButton; lblCounter: TLabel; lblAttempts: TLabel; Image1: TImage; edtUsername: TEdit; lblUserName: TLabel; procedure btnCloseClick(Sender: TObject); procedure btnLoginClick(Sender: TObject); private { Private declarations } public { Public declarations } end; var frmLogin: TfrmLogin; implementation uses MainMenu, TeachersMainMenu, ViewEditTheData, Globals_Unit; var LoginDataArray: array of TLoginData; counter: integer; Password, username : String; Count1, Count2 : integer; Temp: TLoginData; {$R *.dfm} procedure TfrmLogin.btnLoginClick(Sender: TObject); var SearchName : string[10]; SearchCode : string[3]; begin Password:=edtPassword.Text; UserName:=edtUserName.Text; btnclose.enabled:= true; if (Password = 'warwickschool2013') AND (Username = 'Staff') then begin edtPassword.text :=''; frmTeachersMainMenu.show; frmLogin.hide; counter:= 0; lblCounter.caption := IntToStr(Counter); end else begin assignfile (LoginDatafile,'C:\Users\NinjaBoffin\Desktop\Delphi\DataFiles\LoginData.txt'); reset (LoginDatafile); LoginDatacounter := FileSize(LoginDatafile); SetLength(LoginDataArray, LoginDatacounter); edtPassword.clear; edtUserName.Clear; for Count1 := 1 to LoginDataCounter do begi

It does not happen every time but randomly. I googled a bit and found this poston stackoverflow.And I started to look into the Delphi code which has the File opening functions using Reset, AssignFile etc. Before, the following function will return the size of a https://helloacm.com/delphi-io-error-103/ given file.function getFileSizeInBytes(const fn: string): integer; var f: File of byte; begin Result := -1; if (FileExists(fn)) then begin try AssignFile(f, fn); Reset(f); Result := FileSize(f); finally CloseFile(f); end; end; end;function getFileSizeInBytes(const fn: string): integer; var f: File of byte; begin Result := -1; if (FileExists(fn)) then begin try AssignFile(f, fn); Reset(f); Result := FileSize(f); finally CloseFile(f); end; end; end;The problem occurred most readily when one logging operation swiftly followed another. The second operation would fail for the above reason. To solve the IO 103 error, using the IO directive {$I-} to suppress the exceptions and {$I+} to turn it on. The variable IOResult indicates that the IO operation is successful if it is zero. For example, the above code could be improved using the IOResu

Are you sure you can write to the directories where the code is installed (the i/o error 103 compiler needs to do this)?. In general the first thing to do, is to re-install the compiler, from a clean download, and try a short one of the example programs. If this works, then move to your code. 'Error 103', normally means a numeric value is out of the allowed range (you get this if you try for example to use a switch statement with a value above 65535).

It also seems to happen if you have two copies of some programs open 'at once', with a semaphore then not being settable. Also, if the application was installed as 'super user', and then you try to run it,
