serial communication and bluetooth (how to communicate between PDA and mobile?)

Hi !

I have a problem ... i have written a program that communicates with IR - serial communication with my pocket pc and my mobile phone. I used for that a part of the little tty-codesample, which you can find in the help of the Visual C++ tools of Microsoft. I changed there some communication options and it worked. But now i want to use that serial communication with bluetooth. Could that work? And one thing is, that i don't know exactly, how i have to setup the settings for that communication (serial). My current setup is like that:

PortDCB.BaudRate = CBR_9600;
PortDCB.fBinary = TRUE;
PortDCB.fParity = TRUE;
PortDCB.fOutxCtsFlow = FALSE;
PortDCB.fOutxDsrFlow = FALSE;
PortDCB.fDtrControl = DTR_CONTROL_ENABLE;
PortDCB.fDsrSensitivity = FALSE;
PortDCB.fTXContinueOnXoff = TRUE;
PortDCB.fOutX = FALSE;
PortDCB.fInX = FALSE;
PortDCB.fErrorChar = FALSE;
PortDCB.fNull = FALSE;
PortDCB.fRtsControl = RTS_CONTROL_ENABLE;
PortDCB.fAbortOnError = FALSE;
PortDCB.ByteSize = 8;
PortDCB.Parity = NOPARITY;
PortDCB.StopBits = ONESTOPBIT;

and:

CommTimeouts.ReadIntervalTimeout = MAXDWORD;
CommTimeouts.ReadTotalTimeoutMultiplier = 0;
CommTimeouts.ReadTotalTimeoutConstant = 0;
CommTimeouts.WriteTotalTimeoutMultiplier = 10;
CommTimeouts.WriteTotalTimeoutConstant = 1000;

That worked for the IR-communication, but not for bluetooth.

Would be very fine, if someone knows a trick to setup for bluetooth communication !!!

Hi,

how is that "Button-bar" (#ab|cde|...|xyz) at the top of the CE-addressbook programmed? That would interest me, because it's fine for scrolling in a listbox.

WinCE.NET driver development

6-Mar-03 5:37

Right. Do this:
In your CChildWnd, declare the following:

protected:
    	CLetterStrip	m_wndStrip;

In the OnCreate handler, create the window. To place it on the top, just like the image on the article, use the following:

DWORD dwStyle = WS_CHILD | WS_VISIBLE;
m_wndStrip.Create(dwStyle, CPoint(0, 0), this, ID_LETTERSTRIP);

To handle the letter commands, use the following message map:

BEGIN_MESSAGE_MAP(CChildView, CWnd))
	//{{AFX_MSG_MAP(CWordList)
	...
	ON_COMMAND(ID_LETTERSTRIP, OnLetterStrip)
	...
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()

In the OnLetterStrip method, use m_wndStrip.GetOption() to retrieve the selected letter. Note that the letter strip is created as a child window, not as a toolbar.

Hey all,

In the near future I'm going to be developing a WinCE.NET driver for a particular piece of hardware that my company makes. As I've never really done anything like this before, I'm looking for as much information as possible on the topic. I've gone through the MSDN site and read all the relevant articles, but I was wondering if there was another source of [good] information about WinCE driver development on the web. Some example code would be a huge help too! Thanks!

Hi All,

Any one is developing application using oracle lite(wireless editon) or Sql Server CE? If so,please guide me.

I wanted to create always connected application using oracle light.

Since it's a always connected thin client I want to push/pull data without using active sync mechanism while user on the move..

Is it psossible to develop application for pocket pc which supports GSM/GPRS connectivity?

If so please provide more information in detail.

Thanks in advance,
Siva

You do understand that this is no small request? It envolves a lot of stuff that cannot be dealt with in a single reply.

Yes. First, you have to set up the connection in the system (bluetooth, IRDA or other). After being set up, you have to use the RAS interface. This will set up a TCP/IP connection over which you can run the sync processes. I did this with SQL CE 1.1 and it worked perfectly.

Hi,

Yes I understood that its very hard to discuss all these stuff in a single reply.

I want to send and receive data packet via RAS.
I don't know how to deal with this ? Can you please give details about this?If you have any sample application please let me know and will be helpful for me.

Thanks in advance.
Siva

Siva,
You don't send anything explicitly through RAS. Instead, you use RAS to set up a TCP/IP connection over which your data packects will be sent and received. Think of RAS as connecting your PDA to a TCP/IP network. When your RAS connection is active, you can use HTTP, FTP or other protocol to exchange data. Handling RAS itself is not very complex, and involves the use of the RAS* APIs and the WM_RASDIALEVENT message. This message is used as a notifier to a specific window to help monitor RAS dialing events. If you are using MFC, handle it like this:

LRESULT CDlgRas::WindowProc(UINT message, WPARAM wParam, LPARAM lParam) 
{
	//
	// Special check for WM_RASDIALEVENT message
	//
	if(message == WM_RASDIALEVENT)
	{
		return OnRasDialEvent(wParam, lParam);
	}
	return CDialog::WindowProc(message, wParam, lParam);
}

Here is an outline of the sequence to dial through a RAS connection:
RasEnumConnections checks if there are any open RAS connections (you can only have one). If there is a connection open, check if it is the one you want with RasGetConnectStatus. To open the RAS connection, use RasGetDialParams, followed by RasDial. In this API, use the window that will receive the WM_RASDIALEVENT messages. To close the RAS connection, use RasHangUp.
If you want to read some serious discussion on how RAS works under Windows CE 3.0, read "Windows CE 3.0 Application Programming" by Nick Grattan and Marshall Brain, from Prentice Hall.
Good luck!

Multiple Toolbars

#realJSOP4-Mar-03 10:49

How does one implement muiltiple toolbars?

Our app starts out with a commandbar (menu + buttons), but depending on what the user does in the menu, we want to display another toolbar (or even better, a commandbar with just buttons that replaces the original one until they're done with the new toolbar).

Does anyone have any hints they'd like to share?

The project I'm working on right now has a similar functionality. I supports the normal command bar, plus a toolbar at the top of the screen. Here is the code I've used:
Header for frame:

.
.
.
protected:  // control bar embedded members
	CCeCommandBar	m_wndCommandBar;
	CChildView    m_wndView;
	
	CToolBar	m_tbDummy;
.
.
.

Implementarion of frame:

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
	if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
		return -1;
	// create a view to occupy the client area of the frame
	if (!m_wndView.Create(NULL, NULL, AFX_WS_DEFAULT_VIEW,
		CRect(0, 0, 0, 0), this, AFX_IDW_PANE_FIRST, NULL))
	{
		TRACE0("Failed to create view window\n");
		return -1;
	}
	m_wndCommandBar.m_bShowSharedNewButton = FALSE;
	m_ToolTipsTable[0] = MakeString(IDS_NEW);
	m_ToolTipsTable[1] = MakeString(IDS_FILE);
	m_ToolTipsTable[2] = MakeString(IDS_MHELP);
	m_ToolTipsTable[3] = MakeString(IDS_CUT);
	m_ToolTipsTable[4] = MakeString(IDS_COPY);
	m_ToolTipsTable[5] = MakeString(IDS_PASTE);
	m_ToolTipsTable[6] = MakeString(IDS_ABOUT);  

	if(!m_wndCommandBar.Create(this) ||
	   !m_wndCommandBar.InsertMenuBar(IDR_MAINFRAME) ||
	   !m_wndCommandBar.AddAdornments() ||
	   !m_wndCommandBar.LoadToolBar(IDR_MAINFRAME)  ||
		!m_wndCommandBar.SendMessage(TB_SETTOOLTIPS, (WPARAM)(6), (LPARAM)(&m_ToolTipsTable[1])))
	{
		TRACE0("Failed to create CommandBar\n");
		return -1;      // fail to create
	}
	

	m_wndCommandBar.SetBarStyle(m_wndCommandBar.GetBarStyle() |
		CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_FIXED);

	if(!m_tbDummy.Create(this, WS_CHILD | WS_VISIBLE | CBRS_TOP) || !m_tbDummy.LoadToolBar(IDR_DUMMY))
	{
		AfxMessageBox(_T("Failed to create dummy!"));
		return -1;
	}
	m_tbDummy.SetHeight(20);
	return 0;
}

Cheers.

This is what I did, and all I've managed to do is to get the CommandBar to dissappear altogether. What's more, when I shut the app down and restart it, the original commandbar is STILL gone (in the emulator).

In MainFrm.h:

class CMainFrame
{
   ...
   ...
private:
	CToolBar m_barProcess;
	CToolBar m_barAnnotate;
	CToolBar m_barZoom;
	CToolBar m_barVideo;
	CToolBar m_barAVI;
	CChildView m_wndView;
	UINT m_currentBar;

	BOOL CreateOtherCommandBars();
	void HideCurrentToolbar    ();
	void ShowThisBar           (UINT newBar);
	void ShowMainCommandBar    ();
};

In MainFrm.cpp:

//---------------------------------------------------------------------------

	m_ToolTipsTable[3] = MakeString(IDS_CUT);
	m_ToolTipsTable[4] = MakeString(IDS_COPY);
	m_ToolTipsTable[5] = MakeString(IDS_PASTE);

What I'm trying to get is what Pocket Word does. There's a button on the commandbar that brings up an additional toolbar. I have tried a number of approaches to this, but I can't get it to work. I've almost decided that PocketPC 2002 is equivalent to "hell on earth".
