Re: Pull/Push data using either OracleLlite(Wireless Technology Edition) or SQL Server CE

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,
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

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:

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

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".

I believe you should create a CToolBar in your main frame using the CBRS_BOTTOM style. Hope this is not another blind alley...

I want to programatically remove/add the keyboard annunciator from the taskbar.

I suspect that I have to use Shell_NotifyIcon, but I don't know where to find the ID of the icon to remove.

Any suggestions?

Check out the SHFullScreen API. In the dwState parameter, you can specify either SHFS_HIDESIPBUTTON or SHFS_SHOWSIPBUTTON.

I tried this in the OnCreate function in CMainFrame, but it returned FALSE. The hwnd wasn't NULL, so I can only assume that the iPAQ doesn't support the function call, or I'm not calling it in the right place.

That's a shame... The only thing I can recall is that maybe your HWND is not top-level, but being a CFrame-derived it should be... Anyway, examples point to the use of this function on the InitInstance. I'm trying to use it there but is also not working, although no error is returned now.

#realJSOP13-Mar-03 7:24

I'm making the call in CMainFrame::OnCreate. Wouldn't it be a safe guess to say that the CMainFrame class represents the top-level window at it's creation?

Now I have it. After "hiding" the SIP button, you have to resize the frame window in order to cover it. Also, the toolbar must be hidden.
