Loading Forms - Data Aware |
Fri, Nov 12 2010 10:21 AM | Permanent Link |
Sean McDermott | Forgive me for being a little off topic. DBISAM 4.3 D2009 Professional
When I start my program it processes it's splash screen showing load progress but this little splash screen becomes half trashed for about 2 seconds where you can see the splash screen and the underlying yet not quite populated main form. In the end it doesn't look very professional. I have measured load times on screens and all should be OK. I have also played with Enable and Disable controls to save data aware slow ups but it still doesn't help. I even enlarged the splash screen to the main form size to cover this problem but it still doesn't hide enough. The data files are quite small with maybe 300 records although one table does have 454 fields. Any ideas, no matter how brief appreciated, thanks, Sean |

Sounds as though the splash screen is being released to early and the main form isn't ready to update. There are various splash screen implementations out there that may be worth a look - I'm using Peter Below's threaded splash screen. Roy Lambert |

I have the Splash Screen.hide and release just prior to the Run Application so thought that should be good enough. Cheers, Sean |

Cheers, Sean Just doing a quick test in D2006 it goes Application.Initialize; Application.CreateForm(TForm1, Form1); form1.OnCreate; Application.Run; form1.onshow form1.onactivate So I would have thought you right but Delphi is sometimes a law to itself Roy Lambert [Team Elevate] |

Tony Pomfrett | This works for me:
begin frmSplash := TfrmSplash.Create(Application) ; frmSplash.Show; Application.Initialize; frmSplash.Update; Application.Title := 'My Application'; Application.CreateForm(TDM, DM); frmSplash.Hide; frmSplash.Free; Application.Run; end. The datamodule DM does a lot of work, opening remote tables over the internet and and streaming lookup tables to the local computer. The splash screen has a progess bar which is updated with the progress of table copying operations. The main form is created as the last line of DM.Create. |

But DM is non-visual so there's no competition for updating the screen. Roy Lambert [Team Elevate] |
