Active scan on a WiFi NIC, including flush of old scan results - how ?

Hi,

I wrote a program using VC++ that should scan for available wireless networks in the area.

In my SW I use the commands OID_802_11_BSSID_LIST_SCAN and OID_802_11_BSSID_LIST.

My questions are:
1. How can I Force the Wireless NIC to do ACTIVE SCAN (as contrary to PASSIVE scan) ?

2. According to tests that I did, the card does not flush the list between scans, i.e. I get for several scan a result of an AP that was on air during an old scan, but is no longer there, and new scans return's it's data as if it is still there.

A code part that I used is attached - in order to illustrate which functions I am using.

NDIS_802_11_BSSID_LIST* m_pBSSIDList;
m_pBSSIDList = (NDIS_802_11_BSSID_LIST *) VirtualAlloc (NULL,
                                                        sizeof (NDIS_802_11_BSSID_LIST) * NUMBEROF_BSSIDS,
                                                        MEM_RESERVE | MEM_COMMIT,
                                                        PAGE_READWRITE) ;


memset (m_pBSSIDList, 0, sizeof (NDIS_802_11_BSSID_LIST) * NUMBEROF_BSSIDS);

// Do Scan
oidcode = OID_802_11_BSSID_LIST_SCAN;
DeviceIoControl (m_handle,
		IOCTL_NDIS_QUERY_GLOBAL_STATS,
		&amp;oidcode,
		sizeof(oidcode),
		(ULONG *) NULL,
		0,
		&amp;bytesreturned,
		NULL);

Sleep (6100); // According to the documentation the result of the scan should be valid after 6 seconds.
// The original line was delay of 2000 mSec. find out why...
//Sleep (2000);

// Read scan results
oidcode = OID_802_11_BSSID_LIST;
if (DeviceIoControl(    m_handle,
			IOCTL_NDIS_QUERY_GLOBAL_STATS,
			&amp;oidcode,
			sizeof(oidcode),
			(ULONG *) m_pBSSIDList,
			sizeof(NDIS_802_11_BSSID_LIST) * NUMBEROF_BSSIDS,
			&amp;bytesreturned,
			NULL) == 0)
{
	// List failed
	return NULL;
}
else
{
	return m_pBSSIDList;
}

If you have any idea of how can I solve my problems, or if you see that I forgot any important line- please let me know.
I am open to hear about completely new ways to do this. only requirement is that I will use VC++.

Thanks a lot,
--Amit.

Reading data from and from phone and PC

This is for a PC app, not a mobile phone app, in VB.NET or C#. I am still assuming this is the best forum for the question.

What is the best way to go about writing a program using the .NET framework and free tools available to access information on a cell phone and transfer files in both directions? This is a broad question, since I would like to know whether Bluetooth or USB is the better way to go. I would also like to know which maker, among the largest (Nokia, Samsung) is easier to use in this way.

Language/Framework choice for Windows Mobile app

nativebyte2-Oct-09 0:33

Hello everyone,

I have been working on an application prototype for couple of months now. The app is used frequently by the user throught the day and make extensive use of GPS for location aware functionality and communicates with server over GPRS/3G. It runs on Windows Mobile at present. We may eventualy want to use as much source code as possible to develop a version of this app for other mobile devices say Netbook/Notebook with a 3G card etc (this way we can re-use business logic and have different UI layer written which is specific to the device). The chosen development language so far has been C++ - MFC because we have been biased towards using C++ for performance reason. I have explored couple of cases to see what suits best for our app development moving forward
- C#/.NET compact framework or
- MFC or
- a Web application may be using Silverlight

Each have a positive and negative point for ex - MFC apps will have small memory footprint considering limited virtual memory on Window Mobile OS but development effort and complexity increases and it is not future proof. C# on the other hand is the choice moving forward because I believe MS will be want .NET CF and many .NET based technologies like Silverlight on Windows Mobile platform, Also you can run .NET CF applications on Desktop most of the time etc etc

My question is - do you know of any case where you made a decision of language and environment for similar application? do you have any advice based on your experiences so far on Windows Mobile development.

I'm biased towards C# for most applications because it is a rapid development language. The amount of effort taken to do most general task is highly reduced by the language facilities. Of course depending on how low level the functionality is that you use you may have to make extensive use of P/Invoking.

Thank you Joel. I work with C# and see the benefits but I need to find some case where it will really turn the decision in favor of managed code using .NET CF. I have a few cases with me but would like to see CPians view before finalizing (I have not made the decision yet and the views I read here will impact that)

On few forums I read posts which advice not to use managed code on Winmo because of performance, battery, and memory foot print issues with any code that requires runtime on mobile devices. What are your views on this?

Start by choosing what platform you want to develop;
I f you want to develop for Nokia there are three platforms available
S40, S60 and MAEMO.

Then you can get Nokia platform sdk from here
That site also has lots of information and tools on developing for Nokia platforms

Best of luck Thumbs Up | :thumbsup:

Hey,
I'm trying to write a Windows Mobile application (C#) that will run on the background and will log to a file all the user input gestures: keyboard, mouse and especially touch (screen touch).

I was wondering maybe someone found/wrote code that does this task or similar that I can use.

I saw that 6.5 WM DKT supports motion-gestures API
but i could use a sample code (C#) and also- that only enable capturing motions in a specific application and not globally.

Thanks

How to connect to sql server 2008 through pocket pc 5.0

Felong15-Sep-09 11:35

15-Sep-09 11:35

hello guys...

Im trying to build a windows mobile application using visual studio 2008,Pocket pc 5.0 using C# and sql server 2008.
all programs are on the same laptop.

I almost had everything right except i couldnt connect to the database through the pocket pc.

Here is what i've done so far:

SQL SERVER:
-I enabled tcp/ip connection -> cleared all dynamic ip adress and set the port to 1433. i also enabled the name pipes.
-I enable the sql port through windows firewall.(Control Panel->Security->allow aprogram through windows fire wall->add port

Visual Studio:
-New Project-> smart Device project-> device application
added in the form_load the following code:

<br />
string conStr = "Data source = Computer name\1433; intial catalog = "database name"; integrated security = true";<br />
sqlConnection sqlCon = new sqlConnection(conStr);<br />
sqlCon.Open();//this is where i get "SqlException"<br />

I also tried the followin connection strings

i- conStr = "Data source = Computer name; intial catalog = "database name"; integrated security = true";
ii-conStr = "Data source = C:\\"path of the .sdf file on my computer";
iii- conStr = Data source = ip address\1433; intial catalog = "database name"; integrated security = true";

Device manager:
i installed virtual pc and windows mobile center;
openned device manager from visual studio, right click on pocket pc 5.0->Connect;
when connected i configured it to enable NE2000 PCMCIA adapter and use attached network card
i then cradel it and it connected well with the DMA.and in windows mobile center it showed connected.

now when i run the application(F5); i get an sqlException when openning the connection

this is a headache but i need a soluttion.

i have a some additional questions:

1- can i connect directly to sql server database engine and access the database(which isent compact).mdf file.
or cant i because pocket pc only connects to sql server compact edition database(.sdf)

2- Am i suppose to install sql compact on the pocket pc, when i run my application, i find it inside the pocket pc with the database and my application solution

3- is it impossible to connect to sql server 2008 directly through a pocket pc. do i need a websrever, web service, replication, IIS....

im really stock at this point. i have no idea what to do or try next.

i'm findig it impossible connectin to sql server 2008.

PLease Helpppp!!!

thank you anyway..

HEY GUYSS...

WELL AFTER A LOT OF TRIES AND MIES AND FINALLY REACHED TO A SOLUTION.

I COULDNT CONNECT FROM THE POCKET PC TO THE SQL SERVER DIRECTLY. THAT WASENT POSSIBLE, BUT
WHAT I DID WAS, USED MERGE REPLICATION TO GET A SNAPSHOT(COPY) OF MY DATABASE AS COMPACT DATABASE;
I ADDED THIS DATA BASE(THE COMPACT .SDF FILE) AS A DATASOURCE IN MY POCKET PC PROJECT WHERE THE CONNECTION STRING IS: THE LOCATION OF THE DATABASE IN THE THE POCKET PC:
<datasource =="" "\program="" file\project="" name\database="" name.sdf";="">
this is how its written
<@"Data Source=""\Program Files\Final_Project\Bill_Sender.sdf">

this is the connection string to the database
<
public string ConStr = @"Data Source = \Program Files\Final_Project\Bill_Sender.sdf";
public SqlCeConnection connection = new SqlCeConnection(ConStr);
connection.Open();
>
in this case u can open connection easyly, update on the database and then synchronise back with the server which will save any updated rows in the database.

this is how i solved my problem.
i also used web services for more complicated calculations, printing and Console output...

hope this helps. and if any1 was so furtunate to connect directly through pocket pc to sqlserver. please let me know.(though i dnt think its possible).. Thumbs Up | :thumbsup:

hope this helps...
regards.
