Speed up Application start?

[Boris Nienke]

Hi,

it's a bit anoying when you have a small tool, writen for .NET CF, and it
takes around 3 to 5 seconds (and more, depending on the device etc.) to
start it up.

Native tools are "just there" (like calculator, or other software like
PencilBox, RepliGo etc.)

I think it has to do with the Framework which needs to startup too - is
that correct?

Is there any way to speed things up? I don't mean the application itself (i
know the tricks to speed up form creation by optimizing the
control-creation-part of the source) - but even when you write a _very_
simple application like "Hello World" it will take some seconds to start...
Native coded it would be there when you press the button - you won't
recognize a great delay.

You know what i mean?

Not an answer but similar question... Is there a way to have the Framework
stuff do what it needs at startup so that we don't wait for it when we start
the app?

You guys might want to look at this

Anyway.. CF apps would load a bit slower than native apps... after all.. the
CLR needs to be loaded first BEFORE your actual program get's loaded.

As i wrote - i allways know that and do that.

But in fact:
- My Application has 4 Forms. Just the Mainform is created at start up (all
others at runtime when i need them)
- On that Mainform is:
1 PaintBox (with a 32x32 Bitmap)
3 Labels
2 Panels (one of them is an invisible placeholder so i could delete it)
1 OwnerDraw ListBox
1 MainMenu with 2 MenuItems
1 ImageList with 3 32x32 Images

That's it. Not a lot to improve i think

- I have an other application with an EMPTY Form (not being created at all)

But when i start any of these applications, it will take a few seconds...
as i wrote... from 3-5 is normal... 6 to 8 could be.

This is not very "smart"

My Users also write me mails about slow perfomance (i'm currently try to
figure out what they mean - but i'm pretty sure it's a GUI Problem -
windows with more controls are simply "too slow" compared with eVB or eVC++
software :'( )

If you're still doing these optimizations by hand, you may want to check out

As for startup performance in general, yes, it definitely could be better.
However, I believe after the app starts, it is faster than eVB. You may
want to try a caching architecture such as I describe in an OpenNetCF
