Well that's something I haven't figured out yet. If you find the answer, please let me know.

Greetings.
I'm thinking of starting a project that consists on the creation of a mobile voting system, where the voters use PDAs and send information to a central laptop or desktop. Since it's supposed to be as mobile as possible i wanted to communicate from the PDAs to the laptopts without any extra hardware like a wireless router or a switch.
I've been reading about ad hoc networks and the seem to be exactly what i want, but i'm not sure how to make it happen. I have for now been able to create one in my laptop and get my PDA to detect it and connect to it. But not only cant i define any of the IP setting like the subnet mask or the IP itself, but also i cant ping from the laptop to the PDA and vice versa.
Before i get more deeply into this, do you think an ad hoc network is the way to go, or should i consider another option?

Why not try with Bluetooth?

What's the range and stability i can get with a bluetooth network? The kind of data i'm trying to transmit will be small amounts of bytes everytime the PDA user clicks the send button.

Generally Bluetooth has a range of 10 meters (33 feet). Some dekstop adapters may actually support more, but you will be limited to the range of the device Bluetooth hardware.

Hi all,
I have an ASP.Net 2.0 application that my customers use. I now have the need to allow my customers to connect via their PDAs. Just one ASP.Net page is involved here. This page has a Gridview control and the user can enter some info which updates a SQL table. The gridview has some textboxes where the user can change some values. Pretty standard stuff. So I made the gridview real small so that it will fit on a PDA. Everything works except that my textboxes are very wide. I tried making the width small but no luck. But other properties like font=bold, font-size, forecolor, etc. I can change and these change do appear on the PDA. But everything I try to make the width small fails. It is very frustrating since this will perfectly if I can just get these darn widths correct! I know there is a mobile framework and special controls just for mobile devices. But that would require me to write a new web page and learn about these new controls. I was hoping I could salvage my existing web page. Can anyone help?
Thanks,
Bob

I created a web page for the purpose of learning about the ObjectList control. The list items are not displaying after I add a Footer Template via the designer (they display fine if I don't use a footer...autogenerate is set to 'no'). Am I required to use an Item Template if I use a Footer Template? Also, can anyone recommend a good book for building mobile web apps with VS 2005? My code is below:
Note: ObjectList control displays paging information for service call paging and acknowledgement.
<mobile:Form id="Form1" runat="server">
<mobile:Label ID="Label1" Runat="server" Alignment="Center">Unacknowledged Notices</mobile:Label>
<mobile:ObjectList ID="NoticeList" Runat="server" Alignment="Left"
CommandStyle-StyleReference="subcommand"
OnItemCommand="Notice_OnItemCommand" LabelField="PageID" AutoGenerateFields="False"
LabelStyle-StyleReference="title">
<Command Name="Acknowledge" Text="Acknowledge" />
<DeviceSpecific>
<Choice Xmlns="http://schemas.microsoft.com/mobile/html32template">
<FooterTemplate>
<mobile:Label ID="Label4" Runat="server">My Footer</mobile:Label>
</FooterTemplate>
</Choice>
</DeviceSpecific>
<Field DataField="PageID" Title="PageID" />
<Field DataField="SourceID" Title="SourceID" />
<Field DataField="EscLevel" Title="EscLevel" />
<Field DataField="NoticeDtTm" Title="NoticeDtTm" />
</mobile:ObjectList>
</mobile:Form>
.
.
.
Protected Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load
If (Not IsPostBack) Then
Dim array As New ArrayList
' test data
array.Add(New Notice("00323110", "no source", "E2", "08/13/07", "test 1"))
array.Add(New Notice("00323221", "no source", "E1", "08/14/07", "test 2"))
array.Add(New Notice("00324001", "no source", "E2", "08/14/07", "test 3"))
NoticeList.DataSource = array
NoticeList.DataBind()
NoticeList.TableFields = "PageID;NoticeDtTm;SourceID"
End If
End Sub
Thanks.

I believe you can hook your device up to your PC and install the latest .net CF. Otherwise, you may have to contact your OEM about upgrading the CF

No, you would want .NET Compact Framework 2.0

1. Form 1 has a treeview control on it.
2. Treeview control is populated with nodes.
>> How to:
3. When a user taps a stylus on the tree node. The need is to get the x,y coordinates of the stylus position.
4. I can get the stylus position on the Form 1, But when I try to capture the stylus position on the treeview control, could not find a way.
5. This is needed to show the Node Specific Context Menu. Like one menu for Parent and another one for the child nodes.
Help !!

I'm sorry I can't help you.
But I would be interested in how you get the CursorPosition in the Form at all.
I want to draw a line on a Bitmap Graphic from a Point to the position of the cursor.
In .net Framework System.Windows.Forms.Cursor.Position should work.
But I use .net compact on Windows Mobile, where the property Position doesnt seem to exist.
Pls help me.

Hi
I have an interesting problem here, and looking a way out of it:
1. I have three forms in my PPC application.
2. Form 2, has a webbrowser control in it: On a button click:
private void menuItem2_Click(object sender, EventArgs e)
{
//Load the the Login page.
String uritest = "https://login.abc.com";
Uri test = new Uri(uritest);
webBrowser1.Navigate(test);
menuItem2.Text = "Please Wait";
}
3. Form 2, Then there is Document completed event:
private void webBrowser1_DocumentCompleted(object sender,
WebBrowserDocumentCompletedEventArgs e)
{
//Return URL from abc.com, gives me a authentication Key
Uri ttt = webBrowser1.Url;
String trial = ttt.AbsoluteUri;
if (trial.StartsWith("http://"))
{
//Do Something with Authentication Key.
}
}
4. Now I wish to call this Form 2 webBrowser1 control in next form that is Form 3.
5. Form 3, I wish to call the webBrowser1 here. Further the need is to refresh the url "https://login.abc.com". So that a new authentication Key can be retrieved from the "https://login.abc.com".
How this can be achieved in Form 3?
Regards
Arun

Hi All!
I have simple application running under Windows CE 4.2, using compact framework 1.0 SP3.
There are two timers (threads) operating in the program which read/manipulate a common variable of type integer. To prevent critical section collisions I am using the Threading.Monitor.Enter / Exit methods to acquire and release a lock on the variable in question.
The Enter method call works. The Exit method call throws an exception, and I don't know why.
Here is a sample chunk of code.
<br />
Public Class FormMain<br />
Inherits System.Windows.Forms.Form<br />
#Region " Windows Form Designer generated code "<br />
<br />
Public Sub New()<br />
<br />
MyBase.New()<br />
<br />
'This call is required by the Windows Form Designer.<br />
InitializeComponent()<br />
<br />
'Add any initialization after the InitializeComponent() call<br />
<br />
End Sub<br />
<br />
'Form overrides dispose to clean up the component list.<br />
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)<br />
MyBase.Dispose(disposing)<br />
End Sub<br />
<br />
'NOTE: The following procedure is required by the Windows Form Designer<br />
'It can be modified using the Windows Form Designer. <br />
'Do not modify it using the code editor.<br />
Friend WithEvents inputTimer As System.Windows.Forms.Timer<br />
Friend WithEvents outputTimer As System.Windows.Forms.Timer<br />
<br />
Private Sub InitializeComponent()<br />
Me.inputTimer = New System.Windows.Forms.Timer<br />
Me.outputTimer = New System.Windows.Forms.Timer<br />
'<br />
'inputTimer<br />
'<br />
Me.inputTimer.Enabled = True<br />
'<br />
'outputTimer<br />
'<br />
Me.outputTimer.Enabled = True<br />
Me.outputTimer.Interval = 500<br />
<br />
Me.Text = "Threads"<br />
<br />
End Sub<br />
<br />
Public Shared Sub Main()<br />
Application.Run(New FormMain)<br />
End Sub<br />
<br />
#End Region<br />
<br />
Private _inputs As Integer = 0<br />
<br />
Private Sub inputTimer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles inputTimer.Tick<br />
Try<br />
Threading.Monitor.Enter(_inputs)<br />
<br />
_inputs += 1<br />
<br />
Threading.Monitor.Exit(_inputs)<br />
Catch ex As Exception<br />
MsgBox(ex.Message)<br />
End Try<br />
End Sub<br />
<br />
Private Sub outputTimer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles outputTimer.Tick<br />
Try<br />
Threading.Monitor.Enter(_inputs)<br />
<br />
_inputs = 0<br />
<br />
Threading.Monitor.Exit(_inputs)<br />
Catch ex As Exception<br />
MsgBox(ex.Message)<br />
End Try<br />
End Sub<br />
End Class<br />
So if you can tell me what I am doing wrong in the .Net Compact Framework, I would appreciate it.
Thanks,
j.
