Is there a way to uniquely identify a Windows Mobile 5.0 device? I am using web services to sync data and I want to be able to identify which device is being synced so I can send only the needed data.

I'm assuming each Windows Mobile installation has a guid. Does anybody know?

I get the impression that those solutions are completely native code. I'm using C#. I'd like to use managed code. I could use System.Net.Dns.GetHostName(), but that's unreliable for uniqueness.

Yes that is correct, the .NET Compact Framework / Windows Mobile OS doesn't provide any managed way to easily access the unique device id.

However this shouldn't be too much of an issue, since it can be worked around via a little bit of Platform Invoke code. For example www.pinvoke.net has a page discussing how you could do this on a Windows Mobile 5.0 or higher device via a function called GetDeviceUniqueID at http://pinvoke.net/default.aspx/coredll/GetDeviceUniqueID.html

Hope this helps,

Drawing to custom control surface help please

Hi anyone!

I am trying to draw to my custom control with VS2005 with compact framework 2.0.
My control and a second class which references its Graphics object are seperate
but in the same file... i create my second class and attempt to draw small images
on the control using its graphics object reference at later stages of the app running.

I get an ObjectDisposedException, but I understand what this means, but is there anywway
I can reference the controls drawing object just before i process the drawing code?
or any other work around for that matter! thankyou in advance for this!

Best practice is to do all your drawing in the OnPaint method or in a handler for the Paint event. You can cause a callback into OnPaint by calling the Invalidate method, to tell Windows what part of the control needs to be repainted.

If you want to perform some immediate painting, rather than waiting for the Paint event to fire (which is deferred, in the Windows messaging model, to allow input to be processed at a higher priority than painting operations) follow this pattern:

using ( Graphics g = ctl.CreateGraphics() )
{
   // do drawing here
}

The documentation for CreateGraphics specifically says, "The Graphics is only valid for the duration of the current window's message." You are not allowed to save it and reuse it.

The technical reason behind this is that Device Contexts - the Windows data structure behind the Graphics object - are expensive, and the system only keeps a small pool of them available. If you were to retain them, the pool would quickly run out and no-one would be able to draw anything. So the Framework automatically gives it back at the end of processing every window message.

You still need to remember everything that you've drawn anyway and be prepared to redraw it in OnPaint. Windows does not save your screen layout when something is drawn on top of it (the start menu, a notification bubble, another application), you have to repaint it when the obscuring object is removed.

The best resource for understanding Windows' drawing and events model is Charles Petzold's book "Programming Windows, Fifth Edition". Yes, it hasn't been updated in 10 years. It targets desktop Windows. It uses the C programming language. The fundamentals are the same between the desktop and CE, and they haven't changed since Win32 was introduced with NT 3.1 in 1993.

If you do turn your hand to the desktop, note that Windows Vista with Aero now does save your drawing because you're not actually drawing to the screen, you're drawing to an off-screen bitmap which the graphics card combines with all the other windows' bitmaps to produce the screen output. You should still do all your drawing in OnPaint so that the drawing can be synchronized properly.

Hello all,

Latelt I have been complicating my life with more programming that i can handle. Now I am developing databases applications on the pocket pc and using Data on the Run to design them on the fly but I would like to use them directly from my device, anyone knows how? And how can i use a "access database" from the pocket pc itself?

Or even better how can i use databases on the pocket pc? I tried to use sqlce but not luck, probably bad installation or something like it.

I got a php and asp server for the pocket pc and since i don't have a computer i will be creating websites with php and asp in the pocket pc... cool huh!?

best regards,

Luis

Re: Auto-upgrade through web service

8-Feb-08 4:06

I'm wondering how to implement an auto-upgrading system for a windows mobile (C# .NET 2.0) application that works as well as ClickOnce or something similar. The app would communicate to a web service to get patch info and the actual files as well.

Does anybody know of an article that explains how to impliment an upgrade system for a mobile application?

I've read a few articles on transfering files over a web service, so that's as much of a hurdle.
