WinCE-based smartphone provides RAPI (Remote API)for remote control of device.
A way of invoking a DLL function in smartphone from PC is to call
CeRapiInvoke() function.

The barebone code looks like
CeRapiInit();
CeRapiInvoke(L"MyDLL.dll", L"Myfunc", cbOutBytes, pOutBuffer, &cbInBytes, &pInBuffer, 0);
CeRapiUninit();

In Myfunct, I put one line of code: CreateFile(...) to see if a file was created as a result.

But this is failing. I have searched for a hint or solution inside MSDN to no avail.
Other functions such as CeCreateFile(), CeReadFile(), CeWriteFile() worked properly
so I am sure the connection between PC and phone is well established.

Please give me helps.
Thany you in advance.

Best regard,
Cho

Did you try using RAPI?

Dear all,

I have a problem when building an application for Pocket PC using eVC 3.0

Here is some code:

hr = CLSIDFromProgID(POA_OBJECT, &clsid);<br />
if (FAILED(hr))<br />
{<br />
	AfxMessageBox(_T("Fail to load CLSID"));<br />
} else 	{<br />
	hr = CoCreateInstance(clsid, NULL, CLSCTX_INPROC_SERVER, IID_IPOutlookApp, (LPVOID *) &(polApp));<br />
		if (FAILED(hr))<br />
		{<br />
			err = GetLastError();<br />
			sprintf(str,"Fail to load CoCreateInstance %d",err);<br />
			AfxMessageBox((CString)str);<br />
		} <br />
	}

I got error message:

I try to find some answers on news groups and did following these guides by adding:

I solve the problem by inserting the following lines at the top of the application's header file (I include it in other files as needed):

#include "resource.h"       // main symbols
#include <comdef.h>
#include <pimstore.h>


_COM_SMARTPTR_TYPEDEF(IPOutlookApp, __uuidof(IPOutlookApp));
_COM_SMARTPTR_TYPEDEF(IAppointment, __uuidof(IAppointment));
_COM_SMARTPTR_TYPEDEF(ITask,        __uuidof(ITask));

Then, on the application cpp file:

#include "stdafx.h"
#include "MainFrm.h"

#include <initguid.h>
#include "Application.h"

IPOutlookAppPtr	g_pPoomApp;

The linker does not complain...

Hi everybody,

Thought it best to post this message here.

Iv'e been programming in VB.Net for about a year now (Mainly Windows applications). My boss now wants me to start developing mobile appliations. Just want some advice on where to start studying.

Would you suggest I continue to learn to do it in VB.Net or Embedded Visual Basic. The only reason I ask this is that there seems to be more documentation available for Embedded VB.

Many thanks

Hi
I recommed to use VB.net; there is no a big difference etween mobile and desktop apps in .et framework

eVB seems to have more docs ;
because the MSDN docs are for both .net framework and the compact framework no separation here Smile | :)

if u move to eVB u will be downgrading ur skills ; there is no types there [all variables are variant] no Try/Catch [just on error]

How to pass parameters to a running program?

HI~

Is there any function in eVC++ which can pass some parameters to a running C# program?

"CreateProcess" can pass some parameters as a argument when a process start. However, how about the process is running?

Thanks~

Clicked Event on TextBox

I'm doing Embedded Development using Visual C#, VS.NET 2003 & PPC 2003 SE Emulator. I have a TextBox Control and I want to change the BackColor of it when someone clicks on it. Apparently Windows Forms Designer doesn't have the Click Event on the list of events available on the Windows Forms Designer but you can generate it from within the Code Editor. The Code Editor gives you the "Click" property when you type "." after the TextBox's name and then, after you type "+=" it detects that you want to generate an event handler displays a tooltip suggesting the rest of the line as in "new EventHandler(textBoxSearch_Click); (Press TAB to insert)". When you do press TAB it generates the new "EventHandler..." line and highlights "textBoxSearch_Click" and gives you another "(Press TAB to insert)" tooltip which will generate the "textBoxSearch_Click" handler in the current Form class. I put my code in the handler but nothing happens when I click on it. I ran it through the debugger putting a breakpoint inside the handler and nothing at all!! The program behaves as if there is no click event handler on the TextBox. Note that all the other event handlers for my other controls on the form work fine. But those other event handlers where generated through the Windows Forms Designer. Any suggestions?? Ideas??

TIA

I'd like to manage my Pocket PC from Desktop computer. For example to create file, or to delete it from Pocket PC. What should i use? Sockets? Or may be i can work with pocket pc like with a disket or any other driver by using the api functions like (CreateFile, DeleteFile)?

Re: Is It Possible?

Yes, you can use RAPI (Remote Application Programming Interface wich have all the functions like CeReadFile, CeCreateFile, ...
Take a look at the MSDN for complete documentation.

This works the other way: from within a program on your desktop computer you can delete or create files on your PocketPC. Not the other way.

Hope this helps

when i am writing few assembly language programs, after assembling i found .lnk and .obj files.
what the .lnk files hold and how they r built?. why there is change in opcodes of the instructions?.
Example for Mov 70h,#29h the opcode there is 757029
but for mov r1,#20h. it is giving some other opcodes.
why there is a change in this?.

Hi,

I am more of an embedded programmer so I this may not be correct for your situation but this is my experience from the past.

'.lnk' files are normally link files, they tell the linker how to join (link) different modules of code, in the old days programmers wrote their own link files, but it is often done by the programming environment now.

'.obj' files are object files, they are intermediate files generated from the aseembler prior to being linked together to form the final program.

Op Code
From your example 'Mov 70h,#29h', 75 will be the 'op code' for the instruction 'Mov', the source & destination are added to the end of it ie 75,70,29 = 757029
So the result for 'mov r1,#20h' will be 75,??,20 where ?? = the address (index) of r1.

Hope this helps a bit.

To all Gurus,
How can I get a handle to the window of item on the toay screen.
I want to refresh a today screen. But this refresh is NOT triggerred by any user input like a Tap etc but from within a DLL.
Can I send a message to the window ? but in that case I would need a handle to the window.
I know the Class Name and Window Name so how can I post a message to the window to refresh?

any kind of Help will be highly appreciated.

FindWindow returns a handle to a window if you know the class name and window name

HWND FindWindow(
LPCTSTR lpClassName,
LPCTSTR lpWindowName
);

GDvay,
Thanks a lot lof replying.

I had tried that (did not work) , There is a problem with find window.
FindWindow doesn't seem to work for The items on the today screen.
I am not sure but it could be because the items on the today screen are child windows and findWindow returns only parent windows. I am not sure whats the parent window.

Have you tried this before ? Do you know of any work around.
I am at a dead stop here.

Dear Experts,
I am a novice student programmer who is touching Embedded Visual C++ for the first time in my life. (Previously only learnt BASIC and Visual Basic).

Currently, I am involved in this project to this simple pda to pda wireless communication. I am currently stuck at the server side of the communication program. (The client program has been written and tested to be working well).

The problem with the server side is that the program does not seems to execute the OnAccept function of the Listening socket(
although it jolly well could create a socket, listen for connection and seems to make the client program aware of its presence
by enable the client able to establish connection with the server whenever the client is attempting to connect the same port
that the socket is listening to). By not doing so, I am unable to create another client socket for communication. (Came to this
conclusion as neither results I have put in the function has appear when excuted)

I have declared the following Classes:

CServerApp (By default generated)
CServerDlg (By default generated)
CListenSocket (Class for the listening scoket. Base class: CSocket)
CLinkSocket (Class for the Client scoket. Base class: CSocket)

Member Variables (Only for the class CServerDlg, the rest does not have any)

IDC_cmdListen
Function: Listen for connection
Type: CButton
Member: m_bListen

IDC_cmdDisConnect
Function: Disconnect current connection
Type: CButton
Member: m_bDisconnect

IDC_cmdStop
Function: Stop all server service
Type: CButton
Member: m_bStop

IDC_Port
Function: hold the value of the port name
Type: int
Member: m_sPort

IDC_Status
Function: hold the value of the text meant for a status screen
Type: CString
Member: m_sStatus
