them; it only takes a minute: Sign up How do I solve I/O error 103 in delphi up vote 2 down vote favorite So Basically I'm in College in the UK (So that's school for Americans (17 years old)) and I have to make a file handling project for my finals. I have done most of it but it's the i/o error 103 realterm login screen that is weighing me down a lot. What I want from the program to do is read the username and password and log the people in. There can be 2 different outputs. 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

It does not happen every time but http://stackoverflow.com/questions/22026948/how-do-i-solve-i-o-error-103-in-delphi 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 given file.function getFileSizeInBytes(const fn: string): integer; var f: File of byte; begin Result := -1; https://helloacm.com/delphi-io-error-103/ 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 IOResult.function getFileSizeInBytes(const fn: string): integer; var f: File of byte; begin Result := -1; if (FileExists(fn)) then begin try {$I-} AssignFile(f, fn); Reset
f: TextFile;) The Line with Rewrite crashes with I/O Error 103: ERROR_TOO_MANY_SEM_REQUESTS (The semaphore cannot be set again.) What does that mean?? What is http://www.delphigroups.info/2/6d/479235.html wrong?

This is Run Time Error as named in old Borland Pascal. The number 103 means File Not Open, but it is not predicted to apear on rewrite function. Please check if it is on this function. I error 103 belive that file is not created correctly and so it is not opened. You may send more code too, that i can se what can be wrong. Adam Quote"Philipp Crocoll"
file ERROR 103 Subject: Windows 7 - Write to file ERROR 103 Posted by: Sumerset sumerset Date: Wed, 3 Mar 2010 Hello, I'm trying to write a component that logs the activity of an application.
