Hi !
Thank you for your response  !
I solved my problem by watching the DSR line (this was not working on the desktop but works fine on the PocketPC). If this line is at 1, the device is connected, otherwise it isn't.
For your question, I had the same problem once but I cannot remeber how I solved it... Try perhaps to pair the devices ?? Or check your BlueTooth settings with the BlueTooth manager...

I have got the two devices paired already and I can't find anything in the manager, unless its there and I am not seeing it ! I wondered if it just happens on iPAQs? Anyway if you do remember how you sorted it let me know, thanks.
Cheers,
Ali

You need to set BtBrowserEnabled=0 for the outgoing COM port that attaches to the other BT device.

hi,
my app is constituted by a http client (ppc emulator) and a http server (desktop).
the server accepts multipart POST.
my problem is that, sometimes the server can just receive the http header sent by the client. i dunno it's the problem of my server or client. 
here is my code segment:
CLIENT:
WebRequest request;
Stream requestStream;
try
{
request = HttpWebRequest.Create(url);
request.ContentType = "multipart/form-data; boundary=" + boundaryString + "\r\n";
request.ContentLength = message.Length;
request.Method = "POST";
request.Timeout = 10000;
requestStream = request.GetRequestStream();
requestStream.Write(message, 0, message.Length);
// Close the Stream object.
requestStream.Close();
// 1. Get the Web Response Object from the request
WebResponse response = request.GetResponse();
// 2. Get the Stream Object from the response
Stream responseStream = response.GetResponseStream();
// 3. Create a stream reader and associate it with the stream object
StreamReader reader = new StreamReader (responseStream);
// 4. read the entire stream
results = reader.ReadToEnd();
reader.Close();
responseStream.Close();
}
catch(WebException webEx)
{
results = "An exception occurred relating to the use of " +
"a web response or request object. The specific exception was:" +
webEx.Message;
}
//Did some type of general exception occur?
catch(Exception ex)
{
results = "A general exception occurred while attempting to " +
"retrieve the requested page." +
ex.Message;
}
SERVER:
private void AcceptCallback(IAsyncResult ar)
{
// Signal the main thread to continue.
allDone.Set();
// Get the socket that handles the client request.
Socket listener = (Socket) ar.AsyncState;
Socket handler = listener.EndAccept(ar);
f1.ShowSystemMessage("\r\nClient Connected!!"
+"\r\n=================="
+"\r\nCLient IP "
+ handler.RemoteEndPoint + "\r\n");
// Create the state object.
StateObject state = new StateObject();
state.workSocket = handler;
handler.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0,
new AsyncCallback(ReadCallback), state);
}
private void ReadCallback(IAsyncResult ar)
{
String content = String.Empty;
// Retrieve the state object and the handler socket
// from the asynchronous state object.
StateObject state = (StateObject) ar.AsyncState;
Socket handler = state.workSocket;
// Read data from the client socket.
int bytesRead = handler.EndReceive(ar);
if (bytesRead > 0)
{
state.sb.Append(Encoding.ASCII.GetString(state.buffer));
f1.ShowSystemMessage(state.sb.ToString());
ProcessRequest(state);
// Check for end-of-file tag. If it is not there, read more data.
content = state.sb.ToString();
// All the data has been read from the client. Display it on the console.
f1.ShowSystemMessage("Read " + content.Length.ToString()
+ " bytes from socket. \r\n Data : " + content );
state.ClearSB();
}//end if
}
thanks

I'm new to wireless development and am looking for a small sample app that would retrun me the signal strength of the wireless client atapted in my CE device. Or just pointing me in the right direction would help to get me started.
Thanks,

Does anyone where there is a good bluetooth info page for windows CE.. the MSDN information is very scathered and incomplete (in my opinion). I can't find the links to most of their examples and the one that did come with the PocketPC sdk does not work.
(I get an error 10050 - meaning network down - but I know bluetooth works because the bluetooth manager on CE finds other devices [This error occurs during WSALookupServiceNext() even though WSALookupServiceBegin() returns successfully]).
If anyone has a good starting point it would be appreciated.
Thanks, Tom.

I figured it out, here is the reason:
I have just had confirmed from Microsoft Technical Support that the Winsock approach to Bluetooth communications will not work in the IPAQ Pocket PC because it contains a Widecom stack rather than a Microsoft implementation. Widecom do provide a SDK but it is expensive (1,395 USD). I know this might be slightly off-subject, but my IPAQ 2210 has two comports, COM5 and COM8, which are supposed to transmit/receive via Bluetooth. Does anyone have any experience in programming these?
Many thanks for everyone's previous helpful comments.

Hi,
Yes, I have tried this on an iPAQ 1945 and it works well. I just treat the Bluetooth as a com port. My only problem is that it always asks me to select the Bluetooth device even though there is only one Bluetooth device.
Please let me know how you get on and if this happens to you. If you want some help I will be glad to help if I can.
Cheers,
Ali

Hi all,
I am compiling a project in EVC4.0 targetting MIPS devices.
I have installed Pocket PC 2003 SDK.
But the MIPS option doesnt appear in the WCE configuration of the EVC4.0 IDE.
I also checked the installation folder of the PPC 2003 SDK,
\\Windows CE Tools\wce420\POCKET PC 2003\Target\armv4.
\\Windows CE Tools\wce420\POCKET PC 2003\Target\x86.
I find only ARM and X86 target. The target folder MIPS is not available in that.
Can any one suggest me where do I get the SDK to build the application for MIPS devices in EVC4.0.
mani.

Hi all
I'm building a C# application to run on a PocketPC. What I want to do is be notified when the device is docked. This way I can connect to our server and refresh some internal information. The info doesn't live on the desktop machine, so it has to be retrieved via a TCP connection.
I've had a good look through the MSDN examples, and I'm feeling a little lost and confused. It speaks about a function called CeRunAppAtEvent which appears to be precisely what I want. But I don't know how to get this running successfully in the C# app.
Any help or even pointers would be greatly appreciated.
Thanks in advance

What dlls i should add to my release if i use MFC in Shared Dll??? And Where can i find them? Because when i try to do it MFC in Static i got this error : Can't build MFC OLE projects using static MFC libraries. Or how to avoid this error??? I think i didn't use OLE, so how to get it out from my project . Thanks.

I do not care for this issue because the Pocket PC already has these DLLs in ROM. If you are targeting a device that does not have them, you should be looking at mfcce300.dll and olece300.dll for MFC 3.0.

I try to get all XML files from pocket pc, that places in "My Documents" and copy them to the Desktop Computer. I do it this way: i start the cycle that looks for XML files, when i found it i try to read it and create new file on Desktop PC and write into this file. But when i try to get size of file, i got "0", and when i read from file i got nothing. Is it because of file search cycle???
Because when i try to open file, and to read from it without "search cycle" i got success. What Am I Doing WRONG?????

What RAPI functions are you using to retrieve the file names? Consider using the CeFindAllFiles function to retrieve all file names in just one call.

Hi,
I want to develope an application that use internal GSM/GPRS cell phone of my pocket pc QTEK 2020 PPC2003, like a modem to connect directly to another PC (with a modem) through a GSM connection. I must use a GSM connection not GPRS, bluetooth, irda an so on.
My questions are:
Are present in .NET objects based on TAPI libraries ?
Is TAPI the right solution ?
Reading on msdn 'modem connection' I don't understant how can I send and receive data.
Has anyone a sample or can redirect to a place where can I find anything ?
There will be in .NET compact framework anything ?
Sorry for all my question and my poor english.
Thanks in advance.

I got document/view based Application. And I got A big structure that i want to dowload to child Dialog. When i do it by DoModal - it takes a lot of time. So i decided load all this structure in Dialog when i start the appliacation, and the just hide or show the dialog. But i had one problem - when i create the dialog, my main programm command bar disapears. Hot to handle it?

Your CDialog will automatically create an empty command bar that it stores in the m_pWndEmptyCB member variable. You could try and destroy this window.

Hi, Thank you so much, for every help.
I did what you said, and now i have another problem:
let me explain:
I make a modeless dialog in CDocument class. Then i call another dialog (DoModal()), and from this dialog i call ModelessDialog->ShowWindow(SW_SHOW). I see my Modeless dialog, but it doesn't responce on any click, no one of buttons works... Like FROZEN. What is it???
|
|
|
|
|
Use ::ReleaseCapture() before displaying the dialog. This happens to me when I open a dialog from a context menu (tap-and-hold) and I solved it by releasing the capture in OnInitDialog.

Hi,
Friends I am new to evc++. Recently I downloaded evc++ 4.0 and its SDK.
I succesfully installed the software and SDK.
Problem is I am unable to connect my evc++ to Emulator.
When I ever try to Execute my program Emulator is opened but after some times I am getting "TimeOut::Connecting to device failed" message.
Every thing is right here like when creating a project I selected Emulator version and before compiling I set Emulator in Debug Combo Box.
Some of my freinds suggestion is that we need to modify in Settings.
But I don't know how to do that.
If you know please tell me how to solve this problen.
Thanks in Advance,
Azghar
