I firstly created a form that will show settings. Then i created a login box that will load a password from an ini file. I originally thought that it was an error with loading the ini file. Though I have isolated it to when I load the settings form. Here is the code for all of them.
The code for the settings screen:
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
StdCtrls, inifiles;
type
TForm1 = class(TForm)
SaveButton: TButton;
AEditA: TEdit;
AEditB: TEdit;
SEditB: TEdit;
PEditB: TEdit;
PLabelA: TLabel;
SLabelA: TLabel;
ALabelA: TLabel;
PEditA: TEdit;
SEditA: TEdit;
ExitButton: TButton;
Settings: TLabel;
ALabelB: TLabel;
SLabelB: TLabel;
PLabelB: TLabel;
AReserveLabel: TLabel;
BReserveLabel: TLabel;
Label1: TLabel;
Label2: TLabel;
Label3: TLabel;
Label4: TLabel;
Label5: TLabel;
Label6: TLabel;
Label8: TLabel;
Label7: TLabel;
procedure SaveButtonClick(Sender: TObject);
procedure FormCreate(Sender: TObject);
procedure ExitButtonClick(Sender: TObject);
procedure AEditAKeyPress(Sender: TObject; var Key: Char);
procedure AEditBKeyPress(Sender: TObject; var Key: Char);
procedure SEditAKeyPress(Sender: TObject; var Key: Char);
procedure SEditBKeyPress(Sender: TObject; var Key: Char);
procedure PEditAKeyPress(Sender: TObject; var Key: Char);
procedure PEditBKeyPress(Sender: TObject; var Key: Char);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
IniFile : TIniFile;
appINI : TIniFile;
APriceA : String;
SPriceA : String;
PPriceA : String;
APriceB : String;
SPriceB : String;
PPriceB : String;
implementation
{$R *.DFM}
procedure TForm1.SaveButtonClick(Sender: TObject);
//Save Button
begin
appINI := TIniFile.Create(ChangeFileExt(Application.ExeName,'.ini'));
APriceA := (AEditA.Text);
SPriceA := (SEditA.Text);
PPriceA := (PEditA.Text);
APriceB := (AEditB.Text);
SPriceB := (SEditB.Text);
PPriceB := (PEditB.Text);
appINI.WriteString('PricesA','Adult',APriceA);
appINI.WriteString('PricesA','Student',SPriceA);
appINI.WriteString('PricesA','Pensioner',PPriceA);
appINI.WriteString('PricesB','Adult',APriceB);
appINI.WriteString('PricesB','Student',SPriceB);
appINI.WriteString('PricesB','Pensioner',PPriceB);
appINI.Free;
ShowMessage('Settings Saved Successfully!');
end;
procedure TForm1.FormCreate(Sender: TObject);
//Displays values as the form is created
begin
{ appINI := TIniFile.Create(ChangeFileExt(Application.ExeName,'.ini'));
APriceA := appINI.ReadString('PricesA','Adult','');
SPriceA := appINI.ReadString('PricesA','Student','');
PPriceA := appINI.ReadString('PricesA','Pensioner','');
APriceB := appINI.ReadString('PricesB','Adult','');
SPriceB := appINI.ReadString('PricesB','Student','');
PPriceB := appINI.ReadString('PricesB','Pensioner','');
appINI.Free;
AEditA.Text := (APriceA);
SEditA.Text := (SPriceA);
PEditA.Text := (PPriceA);
AEditB.Text := (APriceB);
SEditB.Text := (SPriceB);
PEditB.Text := (PPriceB);}
end;
procedure TForm1.ExitButtonClick(Sender: TObject);
//Exit Button
begin
Close;
end;
procedure TForm1.AEditAKeyPress(Sender: TObject; var Key: Char);
var s:string;
begin
s := ('1234567890.'#8); //Add chars you want to allow
if pos(key,s) =0 then begin
Key:=#0;
showmessage('Only Numbers are allowed. Include cents!');
end;
end;
procedure TForm1.AEditBKeyPress(Sender: TObject; var Key: Char);
var s:string;
begin
s := ('1234567890.'#8); //Add chars you want to allow
if pos(key,s) =0 then begin
Key:=#0;
showmessage('Only Numbers are allowed. Include cents!');
end;
end;
procedure TForm1.SEditAKeyPress(Sender: TObject; var Key: Char);
var s:string;
begin
s := ('1234567890.'#8); //Add chars you want to allow
if pos(key,s) =0 then begin
Key:=#0;
showmessage('Only Numbers are allowed. Include cents!');
end;
end;
procedure TForm1.SEditBKeyPress(Sender: TObject; var Key: Char);
var s:string;
begin
s := ('1234567890.'#8); //Add chars you want to allow
if pos(key,s) =0 then begin
Key:=#0;

end;
end;
procedure TForm1.PEditAKeyPress(Sender: TObject; var Key: Char);
var s:string;
begin
s := ('1234567890.'#8); //Add chars you want to allow
if pos(key,s) =0 then begin

end;
end;
procedure TForm1.PEditBKeyPress(Sender: TObject; var Key: Char);

if pos(key,s) =0 then begin
Key:=#0;
showmessage('Only Numbers are allowed. Include cents!');
end;
end;
//End of Settings
end.
The code for the login form:
unit Unit2;
interface
uses
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
StdCtrls, Mask, inifiles, Unit1;
type
TForm2 = class(TForm)
PassEdit: TMaskEdit;
LoginButton: TButton;
PassLabel: TLabel;
InvisiButton: TButton;
procedure PassEditClick(Sender: TObject);
procedure LoginButtonClick(Sender: TObject);
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form2: TForm2;
IniFile : TIniFile;
appINI : TIniFile;
Password : string;
implementation
{$R *.DFM}
procedure TForm2.PassEditClick(Sender: TObject);
begin
PassEdit.Text := '';
end;
procedure TForm2.LoginButtonClick(Sender: TObject);
begin
//if Password = PassEdit.Text then begin
Form2.Hide;
showmessage('test');
Form1.Show;
end;
//end;
procedure TForm2.FormCreate(Sender: TObject);
begin
appINI := TIniFile.Create(ChangeFileExt(Application.ExeName,'.ini'));
Password := appINI.ReadString('Login','Password','');
ShowMessage(Password);
appINI.Free;
end;
end.
This is the project:
program Project1;
uses
Forms,
Unit1 in 'Unit1.pas' {Form1},
Unit2 in 'Unit2.pas' {Form2};
{$R *.RES}
begin
Application.Initialize;
//Application.CreateForm(TForm1, Form1);
Application.CreateForm(TForm2, Form2);
Application.Run;
end.
