InvalidDeviceException

[Cloud Strife]

I'm developing an application for Windows CE 5.0 with Visual Studio .NET
2005
i want to try WindowsMobile.DirectX features, but i'm already stuck in
device initialization!

this is the function that initialize device

public bool InitializeGraphics()
{
try
{
PresentParameters presentParams = new PresentParameters();
presentParams.Windowed = true;
presentParams.SwapEffect = SwapEffect.Discard;

device = new Device(0, DeviceType.Default, this,
CreateFlags.MultiThreaded, presentParams);
return true;
}
catch (Exception e)
{
MessageBox.Show("The sample has run into an error " +
"and needs to close: " + e.Message);
return false;
}
}

when application reach the Device constructor it throws
"InvalidDeviceException".

why?

i have to do something at OS with platform builder ?

thanks

what is windows mobile?
what's the difference between WM and WCE?

how can i upgrade from windows CE to windows mobile ?

Windows CE is highly customizable real time OS, WM is a particular
customization of this OS. WM is intended for PDA/Phone class devices.

It has special simplified UI, PIM features (e.g. Pocket Outlook), supports
only particular screen resolutions and had predetermined API set.

Various APIs on WM targeting end users like outlook e-mail access business
customers and D3DM for gaming support.

You don't "upgrade" from Windows CE to WM, you purchase device with WM
installed.

However, I would guess you have a custom embedded devices, right?

yes, i use an x86 device.
i have platform builder for windows CE 5.0 and i'm developing an
application with visual studio .net 2005 / c#.

you said that WM is a particula WCE customization.
i imagine that i can use D3DM on an OS that is "parent" of WM

but how?

thanks

No, D3DM is part of the WM 5.0 platform, not part of CE, so it's only
available under WM 5.0.

is there some libraries that wrap the windows CE directx for their usage
from managed code?

i've the need to use them

thanks
bye

ps Ilya said that WM is a customization of WCE but if you said that WCE
don't support D3DM while WM does it means that it is not a simply
customization... am i wrong?
