Eric,
My best guess here is that the function for reading the data is being called twice for the first time. You may try adding a counter and increment its value every time data is being read and check its value at the end.
You may also use any sniffer to check for the data being transferred to and fro. Searching over the google, you may find few tools for the same.

Dave

Hi there.
Is there any way I can catch an event, when i plug a cable from my device to a computer?
When there is an active connection between the two devices I want to show a dialog box in my mobile application.

Please check Windows Mobile API
there is lot of system states.
|
|
|
|
|
Can you tell me more specific where I can find these system states?
|
|
|
|
|
Hi
Please search in msdn2.microsoft.com
There are you can find get all system sattes.
|
|
|
|

I found this:
http://msdn2.microsoft.com/en-us/library/microsoft.windowsmobile.status.systemstate.activesyncstatus.aspx[^]
With this I have written the following code:
void activeSyncState_Changed(object sender, ChangeEventArgs args)
{
ActiveSyncStatus status = (ActiveSyncStatus)args.NewValue;
try
{
if (status == ActiveSyncStatus.Synchronizing)
{
MessageBox.Show("Hello world!");
}
}
catch (Exception ex)
{
// Handle Exception
}
}
SystemState activeSyncState = new SystemState(SystemProperty.ActiveSyncStatus);
activeSyncState.Changed += new ChangeEventHandler(activeSyncState_Changed);
But when I plug in my cable nothing happens. But I guess I dont use the right api, because I need to fire my event when a connection is established and not when activesync is synchronizing. Is there any way to do that?

Hello,
I am trying to launch pword.exe using CreateProcess but its failing.
I have used following code : -
BOOL a = CreateProcessW(L"pword.exe", L"", NULL, NULL, TRUE, 0, NULL, NULL, 0, 0);
a = CreateProcessW(L"\\windows\\pword.exe", L"", NULL, NULL, TRUE, 0, NULL, NULL, 0, 0);
Can anybody of you tell me why is it failing?
Thanks in advance!

Try the following which worked for me:
Process myProcess = new Process();
myProcess.StartInfo.FileName = "\\Windows\\pword.exe";
myProcess.StartInfo.Verb = "Open";
myProcess.Start();

Hi,
I'm trying to create a program that interacts with a bunch of wireless sensors, but I'm not sure where to begin since I have no experience in this and had trouble finding information about it. Here are a few questions that will hopefully help me on my way:
1) What language should I program in? And what framework do I need? I am planning on having this application on a mobile device (i.e. cellphone, PDA).
2) How does the sensor send data to the program? What is needed in order for it to communicate with the program? What hardware as well as software frameworks and APIs?
Here's what I'm thinking: I will write my mobile app in C# and have some event handlers. The sensors will be calling the event handlers of that app. Do I need to do some socket programming, such as creating sockets and taking in packets in order for the sensors to communicate with the application? Also, do I need to account for the fact that the transmission is wireless and if so, how?
Any help will be greatly appreciated.
Thanks!

Hi all,
After it seems that I'm finding the way to resolve my previous problem,
now I found another problem.
Please read this simple line of code:
Imports System
Imports System.IO
Imports System.Drawing.Graphics
Imports System.Drawing.Color
----------------------------------------
TextBox1.BackColor = RGB(255, 255, 0)
It generate the following error:
Error 1 Value of type 'Integer' cannot be converted to 'System.Drawing.Color'. E:\Documents and Settings\MI\Documenti\Visual Studio 2005\Projects\TrackPlotter\TrackPlotter\Form1.vb 555 30 TrackPlotter
I tryed the same line code in VB 5 with the expected result to colorize the Box yellow.
Is my C.F. 2.0 crazy?.....Or not?

I think the code that you would need to use is:
TextBox1.BackColor = Color.FromArgb(255, 255, 0)
Or:
TextBox1.BackColor = Color.Yellow
Also, make sure that you have the .Net CF Service Packs installed on your mobile device. (I had a few problems with coloring on my PPC before I installed the .Net CF SP2 on it)
I hope this helps

Hi Mitch,
Thanks for reply.
I have .Net CF SP2 installed on both device and emulator (Windows Mobile 2003 SE).
I know that the code that I would need to use is:
TextBox1.BackColor = Color.FromArgb(255, 255, 0)
The problem I described in the post is born while I was trying to resolve another previous and primary problem (actually unresolved).
This is the main problem:
1)- I need to get an RGB vatue from a txt file (I.E. 65535 for Yellow).
2)- Convert it in Integer or Color (Result is the identical: Appl. retuns a color like Aquamarine instead of Yellow.
3)- Use this value as BackColor property for a TextBox.
But........
TextBox1.BackColor = Color.FromArgb(255, 255, 0)
work correctly (Colorize TextBox Yellow), but it's not good for my application.
------------------------------------------------------
TextBox1.BackColor = Color.FromArgb (65535)
'Color.FromArgb can accept also an RGB Value as single argument.
'65535 is the RGB value of Yellow
Don't work correctly (Colorize TextBox like Aquamarine instead of Yellow).
--------------------------------------------------------
Are 3 days I'm working around....... But Nothing!

Hi all,
After 3 days I resolved problem explained above.
I discovered that in .Net CF 2.0 (may be also others versions), statement Color.FromArgb(Red, Green, Blue) works as expected (correctly)if it's used to reproduce a color structure from a triade of the three R-G-B components values(one value for each component in the order R-G-B),
but if it's used to reproduce a color structure from a color value (I.E. 65535 for yellow), it works with colors components values inverted.
More exactely, it reproduce colors like statement:
Color.FromArgb(Blue, Green, Red)
And then, I resolved problem estracting each single component values from the single color value, and recombined them in Color.FromArgb(Red, Green, Blue), following the normal R-G-B sequence.
Thanks
Marco

hi
how can i get x,y from GPS using PPC in C# code ?
thanks
|
|
|
|

Take a look at the article entitled "Writing your first GPS application" that's on this site. Regarding X and Y I presume you mean Latitude & Longitude.

hi anyone
I'm a computer science student. Now I'd like to upload the picture in my Pocket PC to network
(web application (PHP)).
You have any guildline for me about the above application.

Webservice would be really easy
Create a webservice that acceps a bytearray and a name
Then save the bytearray with the name
I dont know php, but i guess there must be something like bytearray in ASP
If not, witch to ASP.NET

I am writing an installer for my Windows Mobile Application. My application requires CF2 SP2. As that is not included in Windows Mobile 5, I presume I need to distribute it. I don't know what files to include and where to get them. I know how to (and have already of course) install it on my Windows PC, and how to set Visual Studio to automatically deploy it when I debug my projekt, but doesn't help my customers...
Anyone?

The link actually works, great advice

I seriously doubt the punter would even bother to click on the link, not even out of curiousity. Maybe the next post will start "What does this link do if I click it" or "Can somebody tell me how read the f___g manual".

It amazes me why people ask such lame questions, which with 10-30 minutes of research using google that could find an answer and solution and learn something in the mix at the same time.
Are they just lazy and want to be spoon fed?  . One of the reasons I'm reluctant to answer messages in the dev. forums.
