WindowsIdentity in CF 2.0

Hi all,

I was wondering if the WindowsIndentity class was available in Compact Framework 2.0. I have checked and the namespace System.Security.Principal is not there.

My problem is that I would like to retrieve the username (if available) of the user that is logged into an NT domain. I have an equivalent application in normal Windows. In that case, the user can log into an NT domain if he is working via VPN for example or if he logs into the domain directly from a PC connected to the domain. I can then get the username.

Is there a way to do the same thing in Windows Mobile with CF 2.0?

Thanks,
Talal

Console app

Hi all,

I'm writing a console application for WM5 that uninstalls a previous version of my main app, installs the new version, and then restarts the main app.

The problem is, when uninstalling/installing the console app is closed and main app never gets restarted.

How can I prevent the console app from being closed before finishing?

I already used a form app to catch the Closing event and set the Cancel argument to true, with no effect. The form app still got closed down anyway.

--------- CONSOLE APP CODE ---------

Process cabinst = Process.Start(cabfile, string.Empty);<br />
cabinst.WaitForExit();<br />
cabinst.Close();  //this is never called, console app is terminated

Windows Mobile 5's version of the cabinet install system checks for any programs running that are included in the cabinet and shuts them down. If the program doesn't respond to the close message it kills the process.

You'd have to make a copy of the program somewhere else, I think.

Mike,

How do I respond to the close message? Do I need to use PInvoke for this?

I actually copied the console app to a different location and started it from there, but it still shutdown.

I'm under the impression that all .NET CF-based applications are shutdown so I started a VC++ console application.

I'm not a C++ man so I'm having a bit of difficulty. However, uninstalling the previous version doesn't seem to shutdown the VC++ console application as it did with the C# one.

--CORRECTION
My first proof of concept seem to work, that is, the VC++ console app looked like it was still running after the uninstall but it was in fcat shutdown. Any help is much appreciated

Mike,

Thanks a lot. I've finally made it work by simply copying the console app to a different location and renaming it. The WM5 install system does not attempt to close it this way.

Thanks again

There's no built-in way to do it. I built a program to build self-extracting ZIP files, which automatically unpack any contained CAB files when they're run. Unfortunately this was for my employer, so it's their copyright and I can't share it with you.

We used to just build a CAB file with a setup DLL which would extract any contained CAB files, but Windows Mobile 5.0 no longer supports nested CAB installs (two CAB installs running concurrently).

I have an idea of programming a contact list with a different interface (rather than the default address book in windows mobile pocket pcs)

My concern is that how can I retrieve the contact list database that is stored in the pocket pc/sim card, and apply it on my new interface? In other words, I can view the contacts information in both my interface and also the default interface.

I am currently using Visual Studio .NET (C#) and SQL Server Mobile.

Please help! and thank you!

Issue with Type.GetConstructor()

Dr. Spack25-Jun-07 4:58

Hello,

I have a small issue regarding reflection and the Compact Framework 2.0.

I am working with:
- VS.Net 2005
- Compact Framework .NET 2.0
- Windows Mobile 5.0 Pocket PC

So what I want to is a very simple thing:
int[] array = new int[ 42 ];

But I need this done with the help of reflection.

My first idea was:
int[] array = (int[])System.Activator.CreateInstance( typeof( int[] ), 42 );

But unfortunately this does not complie with the Compact Framework. (The overload for the parameters is missing).

My Second idea was:

System.Reflection.ConstructorInfo ci = typeof( int[] ).GetConstructor( new System.Type[] { typeof( int ) } );<br />
  int[] array = (int[])ci.Invoke( new object[] { 42 } );

That compiles in both, the Framework and the Compact Framework, but in the Compact Framework the variable ci is null. Confused | :confused:

Alternatively I tried to get all constructors with:
System.Reflection.ConstructorInfo[] ciArray = typeof( int[] ).GetConstructors();

The result:
FrameWork: ciArray.Length == 1
Compact FrameWork: ciArray.Length == 0 <- Why Confused | :confused:

I am a little confused and I think that this is a bug. (But I don't hope so)

My question is:
Does anyone know another way to create such an array? (The type int should be replaceable with any other type)

Thank you in advance.

Hi,

I want to improve the following query's performance executing on sqlce.

select *
from TABLE_A
where field_a in (select field_a
from TABLE_B
where field_b = '0000162080'
and field_c = '2'
and field_d = '011')
order by field_e

Table_A has index for field_a and Table_B has index for field_b and field_c. How can I rewrite the query to execute faster?

thanks,

How to Connect PC to Nokia Series 60 Phone

Brady Kelly24-Jun-07 22:25

24-Jun-07 22:25

I spent all weekend trying to find out how I can connect from my PC to my Nokia N70 device. I specifically want to access the messaging functionality on the device from my own software. This search proved frustrating and nearly fruitless. In most cases, this can be done using the phone as a straight modem, and using AT commands, but the Series 60 phones don't support AT commands.

I have to find out how to connect Windows to Symbian, and possibly create a service that runs on the phone and processes requests from a PC client. OK, how do I actually connect to the phone? Using Sockets? What is the address of the phone?

USB Removable Drive Detection in Win CE 5.0

cyberanee21-Jun-07 21:03

21-Jun-07 21:03

I have an data-acquisition application in which data-logging is performed constantly and data is stored in a CF Card, which acts as the primary data-storage device for the system.

The Windows CE image that i have loaded has support for automatic detection of USB mass storage devices.

The User can retrive the data from the system (CF Card) thru USB Drive.

There is no screen or console , it is an industrial Controller.

The data acquistion goes on constantly , and the application periodically polls the USB slot to see if the user has inserted any USB Drive in it.

For this, i use the standard CreateFile() function in order to detect if the user has inserted USB Pen Drive into USB slot or not. I get the handle to the device using CreateFile(), is user has inserted it. If he has, then all reqd. data from the CF Card is copied to the USB drive.

if ((hFile=CreateFile(_TEXT"DSK2:",GENERIC_WRITE,
FILE_SHARE_READ|FILE_SHARE_WRITE, NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL, NULL))!=INVALID_HANDLE_VALUE)
{Do further processing}

NOTE: Here DSK2: is the disk number of the Pen Drive

Whenever the user insertes the USB Drive, the OS detects this, and CreateFile function therefore returns successfully with the USB dive handle. Thus, USB Drive is detected.

Now, the problem is that sometimes, although the Pen Drive is inserted, it is not detected by the OS, whearas at other times it is. That is, in the Windows Explorer, where I can see the CF Card mounted as "Hard Disk" and USB Pen Drive as "Hard Disk2", sometimes, this "Hard Disk2" is not seen. It leads me to the conclusion that the USB Dive is not mounted by the Windows Device Manager. Even if i remove the Pen Drive and re-insert it, it will not be detected hence-forth , once it is not detected. I don't know how to make the OS detect it then , the only way i know is rebooting the system. (Which is definetely not the solution!!)

What can possibly be causing this irregular behavior?

At such times, I cannot obtain a handle to the device using CreateFile. Is there any alternate way to obtain access to the USB device, rather than relying on Windows OS, and the Device Manager??

I have also completely checked the hardware, to verify that there is no problem on hardware side, no loose connections etc. Another important point is that the LED on the USB Pen Drive always glows when I insert the Pen Drive, even when it is not detected by Windows CE.

Regards,
CR
