Splash Screen Fade app causing main app to flutter.

Guest

Can someone look at this and tell me why, when I call this from my main app,
it displays fine (fades form in and out) but then before my main app
displays, I see other dialog boxes flash monentarily on the screen and this
delays the main app display?

Here is the fade which I compile to a dll and call from my main app:

using System;
using System.Threading;

private System.ComponentModel.Container components = null;

public Splash()
{
//

//

//

//
this.Opacity = 0;
this.Show();
tmrFadeIn.Enabled = true;

}

base.Dispose( disposing );
}

//

System.Timers.ElapsedEventHandler(this.tmrFade_Elapsed);

this.BackgroundImage =
((System.Drawing.Image)(resources.GetObject("$this.BackgroundImage")));
this.ClientSize = new System.Drawing.Size(384, 184);
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.Name = "Splash";
this.Opacity = 0;
this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
((System.ComponentModel.ISupportInitialize)(this.tmrFadeIn)).EndInit();

}

Thanks for any direction.

I think I found the problem.

Instead of using this line: SplashScreenBasic.Splash.ActiveForm.Close();

I replaced it with: this.Close();

And it seems to work fine.

Thanks for any trouble.
