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 login screen that is weighing me down a lot. What delphi i/o error 103 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.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); edtPass

Join them; it only takes a minute: Sign up Delphi7, I/O error 102, When Assigning a file up vote 0 down vote favorite My teacher assigned me to create a simple project: Create a form, which the user has to complete and when he presses the submit button, then the program should write http://stackoverflow.com/questions/16506869/delphi7-i-o-error-102-when-assigning-a-file all the information in different textfiles (For example, 1 textfile for their first name, onother for their last name etc) (i know it sounds insane, but a project is a project). Anyway, i tried this: procedure TForm1.Button1Click(Sender: TObject); //On Click var F:Array[1..20]of textfile; //20 fields, 1 txt each one Firstname,Fname:string; //Location,Field Begin Firstname:=ExtractFilePath(Paramstr(0))+'User\Identity\FirstName.txt'; //Location Fname:=Edit1.text; AssignFile(f[1],Firstname); Rewrite(f[1],Firstname); writeln(f[1],Fname); closefile(f[1]); end; I searched on the google about this error: I/O error 102, All i found is that delphi does not assign the file, for some reasons. But i still don't get why, the code looks absolutely correct and logical to me, Perhaps what i tried: F:Array[1..20]of Textfile is wrong, the only reason i tried it, is because i wanted to start writing f1,f2,...,f20 What do you think i should do?

It does not happen every time but o error 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; o 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);
