objectlist templates in Mobile Web Applications - Mobile Discussion Boards

Hi.

A good start is to look at the basics.

There are two ways (as least as i know) of programing for mobile devices. The first comes from Microsoft, and is called .NET Compact Framework. To program with this, you have to purchase Visual Studio from Microsoft (Really expensive!).

Or you could try Pocket C or Pocket C#. Search in google for them. Although they're not free, they are less expensive.

The question is that you need a compiler to compile you programs on a mobile device, and both of the mentioned above does this. If you'd like to have a free compiler, there are too, but developement on these can be very dificult, speciallly if you want to make your programs available to many diferent platforms.

I hope that this helps you. Mail me to beniwtv@gmail.com if you want further information about the described above.

thanks for ur information

Hello

I have the following problem. I have 2.cab files programmed and to my Pocket PC transfer.

Then I execute these files and the PocketPC installs it also correctly.

However if I now execute these 2.cab files again, then I get a message
"The program existed already. Would you like to overwrite it?"

And that is the problem, I doesn't want that the PocketPC ask me this.
I want that the PPC overwrite the old program without asking me.

If someone knows any trick or solution I will be very thankful for all possible suggestions

Thanks, bye

As far as I know, this is not possible since this is a Windows issue. Windows looks if the given program is installed and if so it asks you to overwrite it.

If you want to "update" the program silently, maybe it helps to change the program name each update.

Hello, all.
I need to make my own on-screen keyboard application (or virtual driver) on PocketPC 2003.
Does anybody know what technique i must use and where can i find any information about that (source code of example will be better)? I'll greatly appreciate any links.

The on-screen keyboard (as you call this) that come with Windows Pocket PC are the so called "SIP"'s (Software Input Panel). Just search in google for SIP Pocket Pc and you will find information how to program your own SIP.
MSDN (msdn.microsoft.com) is also a great resource.

I hope that this helps you,
Benedikt

Hi every one...

I am trying to build a web mobile application that contains an ObjectList.I have used a stored procedure called GetTelephones()to provide the DataSource of the ObjectList using the code:

public static SqlDataReader GetTelephones()
{
SqlConnection connection=new SqlConnection(ConnectionString);
SqlCommand command=new SqlCommand("SELECT UserName,Telephone FROM IdentityTable",connection);
try
{connection.Open();
return command.ExecuteReader(CommandBehavior.CloseConnection);
}
catch(Exception ex)
{
connection.Close();
throw ex;
}
}

and to bind the ObjectList to the DataSource:

objlCustomersT.DataSource=
FirstWebMob.MobileData.GetTelephones();

objlCustomersT.DataBind();

And the HTML of the ObjectList:

<mobile:ObjectList id="objlCustomersT" runat="server" AutoGenerateFields="False" CommandStyle-StyleReference="subcommand"
LabelStyle-StyleReference="title">
<DeviceSpecific>
<Choice Xmlns="http://schemas.microsoft.com/mobile/html32template">
<ItemDetailsTemplate>
<mobile:Label id="lblName2" runat="server">

</mobile:Label>
<mobile:PhoneCall id=pcCustomer runat="server" PhoneNumber='<%#DataBinder.Eval(((MobileListItem)Container).DataItem,"Telephone")%>'>
</mobile:PhoneCall>
</ItemDetailsTemplate>
<ItemTemplate>
<mobile:Label id="lblName" runat="server"></mobile:Label>
</ItemTemplate>
<headerTemplate>
<mobile:Label id="lblTitle" runat="server" Font-Bold="True" Font-Size="Large">CustomerName</mobile:Label>
</headerTemplate>
</Choice>
</DeviceSpecific>
</mobile:ObjectList>

But when i run the application i get the error:

Must have one or more fields to databind. (Application may have autogenerated fields from an empty DataSource. To clear items, set DataSource to null.)

Before i use the templates I have run the application without templates and it worked successfully but i want to use the PhoneCall Control inside the columns of the ObjectList(in the ItemDetailsTemplate).

Please..Could any one help me to fix this error.

I built an ASP.NET mobile web application last year for fun and hosted it on my home server. I was successful in accessing it with my Sprint phone, which uses the "Obigo 1.1.4 WAP 2.0" browser. Now, I'm with Verizon and my current phone also uses an Openwave WAP 2.0 browser, but I cannot access my mobile web site. When I punch in the URL, it hangs for long time, then it gives me the error "Error: Request timed out".

I asked a friend who is with AT&T to try it on his cell phone, and it works. So, my app is working. I dont know if it's a problem with my new phone's browser software (do I need to upgrade it?), or with the Verizon service (maybe they block something on their network).

Another concern is that my home internet service provider blocks port 80 on our network. So i had to use another port, like 81. So to access my web app, the URL would be something like http://myapp.mydomain.com:81. Could it be that my phone's browser does not recognize this non-default port?

Any ideas? Anyone with Verizon that is able to successful access .NET mobile web apps?

Hello all,

I am trying to create a Smart Mobile/GPS application using .Net 2003 framework. In addition for the GPS support I am using OpenNETCF SDK 1.4 library. I am having problems reading in data from the GPS . The following is my code snippet:

private void button1_Click(object sender, System.EventArgs e)
{
gps.BaudRate = OpenNETCF.IO.Serial.BaudRates.CBR_9600;
gps.ComPort = "COM1:";
textBox1.Text = gps.ToString() + "\n";
gps.GpsSentence += new OpenNETCF.IO.Serial.GPS.GPS.GpsSentenceEventHandler(gps_GpsSentence);
gps.GpsCommState += new OpenNETCF.IO.Serial.GPS.GPS.GpsCommStateEventHandler(gps_GpsCommState);

gps.Start();

}

private void gps_GpsSentence(object sender,GpsSentenceEventArgs e)
{
MessageBox.Show("calling");
textBox1.Text += "calling" ;
textBox1.Text += e.Sentence + " ";

}

private void gps_GpsCommState(object sender,GpsCommStateEventArgs e)
{
switch(e.State)
{
case OpenNETCF.IO.Serial.GPS.States.Running:
textBox1.Text += "GPS Started";
break;
case OpenNETCF.IO.Serial.GPS.States.Stopped:
textBox1.Text += "GPS Stop";
break;

}
}

When I run the code using a pocket PC emulator , the code fires gps_GpsCommState event (it always shows the message GPS started even when its not connected) , and more importantly it does not fire the gps_GpsSentence event ever. What is the problem?? Could anyone help me out with this. I would be greatly obliged. If you of any other way to read in data pls lemme know. Also let me know what is the problem with the code.

I am trying to create an MP3 player for Windows CE. What kind of SDK that I can use to decode the MP3 file, and where can I get it (for free.., hopefully)?

Thank you

I am trying to create an mp3 player for Smartphone (WM 5.0) using WM Player 10
Have you solve problem with your mp3 player ?

Fortunately, I have tried using SDK from FMOD, and it worked! Smile | :)

We can use FMOD very simple and easy, just a view lines of code...

Hi!

How can I develop a program for a pocketpc/winCE that will automaticly start at boot, and run in the background. It would also be nice to make a system tray icon appear which the user can doubleclick to access the program.

Is this even possible? Or are there any alternative ways to go about this sort of funcionality?
Kind of new to Compact Framework development...

thanks!

Is rapi.dll freely distributable with a third party software? My problem is that i am using its functions to communicate with a pocketpc using Java. Now, I dont know whether I can distribute this dll freely along with my software.

Waiting for a reply..

This URL gives RAPI.dll http://www.dll-files.com/dllindex/dll-files.shtml?rapi[^]

I think it should be part of Windows CE SDK, whose distribution terms bound rapi.dll also.

I am working on an application that has different features built in for parsing traffic logs for the television broadcast industry. Marketing wants to sell each feature seperately or as a full package. What would be the best way to turn on and off these features short of having to do seperate builds for each of them. Also if at a later date the customer wants to add features to his existing software without having to send them a new build.:->

Any help will be GREATLY appreciated.

Hi!

How can I create a program that works just like a normal Windows Service for Windows CE?
I need the program to autostart when the operating system loads, and to do its work without making the user aware of it.

thanks!
