I have a simple Help->About window with about 15 labels,
5 buttons, and 2 web links in VB.NET. It also has 2
pictureboxes, an icon 48x48x32bpp and the other
180x180x8bpp. I am running a decent machine at 2.4GHz,
nothing running to slow it down, but you can see the form
draw each control separately. Making it invisible until
after the InitializeComponent has no effect.
The .NET Framework is supposed to make things run more
efficiently, and when the form is cached it is instant,
but the JIT compiler is slow to run something the first
time it seems. Is there some trick to having the whole
form pop up at once, pre-drawn? The Visual Studio About
dialog is instantly drawn and it is much more complex
than my simple one.

I think it's not implemented in .NET.

Hello Stephen,
I'm not clear about how slow does your form show up. if it's just a
bit slower than the About Box in VS.NET I think this is normal,because the
About Box of VS.NET uses standard common control and the embeded resources,
in other words, all is ready and in memory. So if you want to make your
form show faster, you may set the FlatStyle property of the Button Label as
well as LinkLabel to System,then these controls will be drawn by system. If
you want to show picture more quickly
I think you may try embed it as resource. you may refer to the following
link for more information:
(Note it's about Cursor, you should change to Bitmap)

Is this helpful to you? Please let me know if you still have problem with
this issue, thanks!

Setting the Image property to a file at design-time
automatically creates a resource file for the form and
the code to extract the image from it, so it is already
reading from a resource file. I'm not loading from a
file at run-time. I set the FlatStyle of all controls to
System and it didn't have an effect.

I think Ying-Shen was referring to a Windows resource, not a .NET
resource. Windows resources are harder to work with from .NET, but they
would quite likely be faster, since there's less overhead and they're
already in native Windows format.

Anyway, I suspect that the Visual Studio about box either (1) isn't
written in .NET, or (2) is pre-compiled to native code with ngen, so it
doesn't have to wait for JIT compilation. You could try using ngen on
your app and see if that helps you out.

Also, is your About box the first place your app ever shows a Label or a
LinkLabel? You might see if you can show one of each sometime before
the About box ever appears, so they're already JIT-compiled by the time
your dialog is shown. If JIT-compile time is the issue, then showing
one of each beforehand should take care of it. (This probably wouldn't
matter if you used ngen.)

Hi Stephen,
The resource I referred to is Windows Resource that embeded with you
executable file, thanks Joe. On my machine it shows faster than specifying
an image file in PictureBox.Image. In addition, you set the image in
PictureBox.Image not PictureBox.BackgroundImage? On my machine, setting an
image in BackgroundImage of the PictureBox will make the form draw slowly.

ngen will also make your program a little faster, VS.NET uses this feature,
you may see the ngen assembly list use
ngen /show,but as you can see, since the main assemblies (e.g.mscorlib,
System, Drawing, Winform) are already NGENed, so maybe you are not able to
gain much performance up by ngen.

Thanks!
Be free to let me know if you still have problems on this issue!

I ngen'ed my exe and ran it, no difference. So I started looking at the
files (ngen'ed one and original exe), both have all my variable and class
names blatantly visible just by opening exe in notepad. I ngen'ed again to
make sure and it said "up to date." I ran comp.exe on them and they are
identical. I thought this changed code into native code?? Even if I was
wrong, shouldn't it do SOMEthing?

Hello Stephen,
ngen doesn't ouput an native version of that exe, it just create the
native image and added it to the native image cache.
you may get a list using the example I showed you in my reply. for more
information, you may refer to :

Hi Stephen,
You may try overridding the OnPaintBackground method of your form, and
draw your images in it, this will reduce the delay of displaying image, but
you must postion it by code, and you shouldn't draw large images or your
form might get flicker when moving from the screen edge, however 180x180 is
acceptable in my mind. I feel sorry I haven't find a better way to make the
controls draw faster.
In addition could you tell me why you need draw the form quickly at first
time? thanks!

Here is an simple example:

}

this.button2 = new System.Windows.Forms.Button();
this.button3 = new System.Windows.Forms.Button();
this.SuspendLayout();
//

this.button1.Location = new System.Drawing.Point(352, 88);
this.button1.Name = "button1";
this.button1.TabIndex = 0;

this.SizeGripStyle = System.Windows.Forms.SizeGripStyle.Hide;
this.Text = "Form2";
this.ResumeLayout(false);

}
#endregion

private void button1_Click(object sender, System.EventArgs e)
{
Close();
}

protected override void OnPaintBackground(PaintEventArgs e)
{
base.OnPaintBackground (e);
//draw your image here
e.Graphics.DrawImage(bmp,new Rectangle(5,5,180,180),
new Rectangle(0,0,180,180),GraphicsUnit.Pixel);
}

}
}

Just because it looks unprofessional coming together piece-by-piece, and if
I can notice it on my system it will be worse on slower systems the
application is designed to target.
