Closing a splash screen

I'm wanting to show a splash screen whilst my app starts, but how do I close or destroy it once my main form is active?

I've created the splash by using the Create, Show, Update methods within it's own implementation section.

Thanks in advance
Darren

Hi elkiors,

put code in your application source, like :

{$R *.RES}

var Splashscreen : TSplashScreen;

begin
  SplashScreen := TSplashScreen.Create(Self);
  SplashScreen.Show;
  Application.CreateForm(TAllExamplesForm, AllExamplesForm);
  SplashScreen.Hide;
  SplashScreen.Free;
  Application.Run;
end.

ps. you can use timer to let splashscreen see for a while

Hi Zif,

Thanks alot ... although I did need to change it a bit:


var Splashscreen : TSplashScreen;

begin
  SplashScreen := TSplashScreen.Create(Application); {THIS IS NEW- SELF CREATED AN ERROR}
  SplashScreen.Show;
  SplashScreen.Update; {THIS IS NEW OTHERWISE IT WON'T PAINT}
  Application.CreateForm(TAllExamplesForm, AllExamplesForm);
  SplashScreen.Hide;
  SplashScreen.Free;
  Application.Run;
end.

At least this q didn't run around in circles like the one we just finished on the Update Query stuff

Thanks again

Darren

Hi elkiors,

yep, your correct, I made some mistakes in this one, but it's because it's already a long time ago I made a splash-screen and I thought I still knew it from my head .... seems I don't....

Regards, Zif.

I run my splash in the program.dpr

program Pprogran;

uses
  Forms,
  Unit1 in 'Unit1.pas' {Form1},
  splash in 'splash.pas' {Fsplash},

{$R *.RES}

begin
  Fsplash := TFsplash.Create(Application);
  Fsplash.Show;
  Fsplash.update; {To paint the splash screen}
  Application.CreateForm(TForm1, Form1);
  Fsplash.Close;
  Fsplash.Free;
  Application.Title := 'Title';
  Application.Run;
end.

and in the unit splash I write.....

unit splash;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,
  ExtCtrls;

type
  TFsplash = class(TForm)
    Panel1: TPanel;
    Image1: TImage;
    procedure FormActivate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }

    procedure Delay(Num: longint);

  end;

var
  Fsplash: TFsplash;

implementation

{$R *.DFM}

procedure TFsplash.Delay(Num: longint);
var
   tc :longint;
begin
     tc :=GetTickCount;
     repeat
           Application.ProcessMessages;
     until ((GetTickCount-tc) >= Num);
end;

procedure TFsplash.FormActivate(Sender: TObject);
begin
  Brush.Style := bsClear;
  Delay(5000);
end;

end.

Of this manner I can control the time that want that the splash this active.
