What's the best way to get a good few Pocket PC applets developed for me?

Please email your responses to me.

I am a C# programmer with about 4 years development experience. I currently busy with an Equipment Management System. I want to add a Vehicle Tracking feature on the system. I have done a couple of searches on the net, but the results I get are not specific.

Can anyone plz tell me what Hardware and software I need to use GPS on my windows application.I would most propably appreciate a list of all hardware and software necessary for my application to work, and possibly a step-by-step guidelines.

Programming is not a skill, it's an art.

Hi Arthur,

Either CodeProject or CodeGuru has a very nice article on interfacing to a piece of hardware. I don't recall the details - it has been too long. I recall the article impressed me.

Also, the hardware manufacturer probably has a SDK available. You might have to pick up the phone and call.

Widows Mobile 5.0 Pocket PC and missing .Net Framework

I have a problem making a new Data Source from VS2005. I have made a new
Widows Mobile 5.0 Pocket PC SDK Project. I’m going through Data
-> Add New Data Source… -> Database -> New Connection… -> Microsoft SQL Server Mobile Edition
(or through Server Explorer). I’m creating new database (or browsing existing).
The connection test ends with success and when I press OK I get such message box:
“Unable to find the requested .Net Framework Data Provider. It may not by
installed”

I have installed VS2005 with Widows Mobile 5.0 Pocket Pc SDK – no difference!

What’s wrong?

Multi modal dialog mobile application - crash

sdt2415-Nov-06 5:51

I am producing a mobile application using embedded VC++ 4 which contains multiple dialogs.

It was intended to step through the dialogs using a next button which would open the next dialog and close the current dialog. Also a previous button which does a similar thing.

The code used to open the next and close current is

Class2 dlgClass2(this);
nRetCode = dlgClass2.DoModal();
CDialog::OnCancel();

And for the previous button on the dlgClass2 button
Class1 dlgClass1(this);
nRetCode = dlgClass1.DoModal();
CDialog::OnCancel();

However by continually selecting next on the dlgClass1 and previous on dlgClass2 the application crashes after the 11th or 12th attempt.

Does anyone know please why this is happening? Are you able to close the current dialog or does it need to remain open?

DoModal creates a nested message loop. Eventually you get a stack overflow.

To avoid this, consider using the dialog's Create function. That creates a modeless dialog - messages are then pumped by the main thread's Run function (if all dialogs are modal) or by the most recent modal dialog on the thread.

Hello,

I've digged for a while in the CF2.0 msnd documentation, and I couldn't find any way to send mails like with the .NET Framework. I didn't find any class to send mail. Is there any buil't way to send mails with VB.NET using CF2.0 and vstudio 2005 standard?

Thanks,
Jacobo.

You can find a step-by-step example at http://msdn2.microsoft.com/en-us/library/aa454896.aspx (see Exercise 2 in the example). The example uses CF1.0 but it should work under 2.0.

Mobile Web Application is very new for me. And i tried to make a simple project about it. So i used VS 2003 and created a Mobile Web Application. I used NWB 4.0 to display the page. But the page couldn't be displayed ( the page could be displayed in IE ) . I only saw the earth icon was always moving and nothing more.

So why's that happened? And how could i solve this problem?

"SendKeys" for a mobile device ???

Hi folks,

I have to write a background application for a mobile terminal (equipped with
integrated scaner engine, keyboard, serial port and so on...) with a CE4.2 OS.
The app shall read data from the serial port, do a little magic with this data
(changing some letters against others, deleting carrige returns) and insert the
result into a textbox of the current foreground application.

Serial communication isn't the problem, but inserting the data into the textbox
is a real head-scratcher to me. Confused | :confused:

I wrote a similar application for a normal PC. Then I used the SendKeys class
to to the job, but unfortunately this class isn't available in the Compact
Framework. Frown | :(

I thought about using P/Invoke, but I don't have a clue which function of which
dll I should use... Sniff | :^)

Does anyone have an idea how to solve this problem?

Thanks in advance!

Accessing Oracle from device

I started reading about synchronizing SQLServer CE. It involves IIS, shadow folders and SQL Server 2000.
What if all our data is on Oracle? Without going too deep, is there a way for IIS to use that instead?

I have no IIS experience. If there is a way to avoid that I'd prefer it.

Hi!

I try to develop my first PDA application, and it works fine, until I not use database functionality.
I try to manage an access database via ODBC, but System.Data.ODBC is missing in my mobile solution, what do I need to make this work?

Need solution for Win Mobile 5, and 2003 too.

Or is there better format, or way for databases on PDA?

I have Visual Studio 2005 Professional, and SQLExpress 2005.

If somebody have links for PDA sourcecodes please send to me.

Thanks for help!

SocketRecieveTimeout in .NetCompactFramework

Please read this from MSDN.

In .NET Compact Framework applications, the following options are supported but not working and are currently reserved for future use: AcceptConnection, ReceiveLowWater, ReceiveTimeout, SendLowWater, SendTimeout, and Type.

I am trying to set ReceiveTimeout using SetSocketOption, but throwing exception.

Pls advise the alternate way to set socket receive timeout.

Thanks

SqlCeConnection issues

Hello All,

I'm using cf 2.0 on the emulated ppc 2003 device that is bundled with vs2005. For some reason, when I attempt to connect to my database it throws a sqlexception error with no error message. My code is as follows:

SqlCeEngine engine = new SqlCeEngine("Data Source='\\Program Files\\UCPS\\UPCS.sdf';");
if (!(File.Exists("\\Program Files\\UCPS\\UPCS.sdf")))
engine.CreateDatabase();

SqlCeConnection connection = new SqlCeConnection(engine.LocalConnectionString);
connection.Open();

I can connect to the database on the device just fine. The database has no password. In this code sample, it does indeed find the UPCS.sdf file in the second line and does not try and create a new one. But when I try to open the connection, it errors out with no message. The only data I have is

HResult = -2146233087
StackTrace = StackTrace "at System.Data.SqlServerCe.SqlCeConnection.ProcessResults()\r\nat System.Data.SqlServerCe.SqlCeConnection.Open()\r\nat System.Data.SqlServerCe.SqlCeConnection.Open()\r\nat UPCS.Data.StatusTable.RetrieveStatusRecords()\r\nat UCPS.Main.Main_Load()\r\nat System.Windows.Forms.Form.OnLoad()\r\nat System.Windows.Forms.Form._SetVisibleNotify()\r\nat System.Windows.Forms.Control.set_Visible()\r\nat System.Windows.Forms.Application.Run()\r\nat UCPS.Program.Main()\r\n" string

I would really appreciate any suggestions,

Thanks,
Ryan

using gdi you can draw with transparency

l_Icon is a bitmap

ImageAttributes imageAttr = new ImageAttributes();

// set the transparency of the image to be shown using the selected pixel
imageAttr.SetColorKey(l_Icon.GetPixel(0, 0), l_Icon.GetPixel(0, 0));

// draw the custom graphic
g.DrawImage(l_Icon, dstRect, 0, 0, l_Icon.Width, l_Icon.Height, GraphicsUnit.Pixel, imageAttr);

Virtual IP - Vertical Handoff

kedde17-Nov-06 1:56

7-Nov-06 1:56

Hi! I really hope somebody can help me.

I am doing a school project on vertical handoff. A Linux workstation and a Pocket Pc (windows mobile 2003) are communicating through WiFi and Bluetooth. The system should always choose the connection technology that is best under the current conditions, if for instance the bluetooth connenction is currently being used, and the connection is lost, the system should transparently switch to WiFi, instead and vice versa.
My goal is that the user or an application uses only one ip-connection, hence achieving trancparent handover between the two technologies.

Now let's say the Linux PC has the following adresses:
BT: 10.0.0.1
WiFi: 10.1.1.1
and the PPC has:
BT: 10.0.0.2
WiFi: 10.1.1.2

Then I what to create a virutal IP (VIP):
Linux PC: 10.2.2.1
PPC: 10.2.2.2

The VIP should then "forward" the communication to the active connection.

I can successfully create a virtual IP on the Linux PC, and then assign this to the currently active connection.

Can I anyhow do the same thing on the Pocket PC?
I would prefer to do this in C# but C++ is an option.

I hope you understand my problem, my english might be a bit rusty, but i will try to elaborate if needed. Thx in advance.
