I would like to know abt the details of communication between PDA and a GPS phone via Serial Port. Can i open a COM Port on PDA and then communicate via that port to the phone using a Data cable or something?

You can read about the basic principles of serial communication with a mobile phone here:

Infrared Communication with your Mobile Phone[^]

The article discusses IRDA, but you can apply these principles to Bluetooth and serial cable as well.

I've created a mobile application which saves data to the SQL CE in the pocket pc. There is a main server which run SQL Server 2000; and is the main database for the client. Is it possible to synch the data inputed in the pocket pc with the one in the main server?

Yes you can sync data. One of the methods is using merge replication.
Other one is RDA.

Check it in SQL CE help.

H/PC Emulator question?

when I build a simple demo with MFC in Debug mode.
It's shows some ASSERT alert. but It's works fine in Release Mode.
what's wrong with it ?

My work environment is evc3.0.

Re: H/PC Emulator question?

Because ASSERT are displayed only in debug mode. Release mode bypasses these ASSERTS.

Hi,

B&W BMP files are stored in PocketPC. These files have to be run length encoded(RLE) and only the data bits(except the header and fileinfo) have to sent to com port.

Does any one have idea?

Different font in dialog

Hi:

Anyone know if in a dialog box in embedded Visual C++, can different control such as textbox can have different font size? if it is possible, anyone can teach me how to do it???

Thank You. Any help will be appreciated

Re: Different font in dialog

João Paulo Figueira29-Dec-03 23:30

Do this:
1 - Create the font you want to use
2 - Retrieve the control's HWND using GetDlgItem
3 - Use SetFont (MFC) or WM_SETFONT to set the font
4 - Destroy the font when the dialog closes

Hi,

I developed a MFC software with the option of using the
MFC library as a shared dll. And when i put the code to run on
a real device of pocket pc 2003, it prompt " cant find some library", what should i do ?

Thanks

Your device may not have MFC installed on it (although most devices do these days, and I'm surprised a 2003 device doesn't).

You may also have a dependency missing elsewhere in your project

Was this a debug build? If so, have you made sure that you have the debug version on the pda? [mfcce300d.dll]

Otherwise, chec for dependencies to any other dll's.

programming win32 Vs MFC in CE

Hi,

What is the pro and cons of programming in pure win32 Vs in MFC for CE ? (beside that MFC is more object-oriented)

And what is the ratio of developers are developing in pure Win32 and pure MFC ?

Thanks

MFC is part of the core OS in CE and PocketPC. It's already there (in memory), so why not use it?

Thanks for your advice.

But i need to program some Win32 code(for link to other library)inside the MFC project,
and I found that those two types of programming(Win32 and MFC) cannot be well-mixed inside the same project, so I consider now to write the whole project in pure Win32, but I am afraid that it is a out-dated practice to program in Win32 and I also will lose many powerful feature of MFC.

Therefore I ask for the comparison of the two programming practice.

Cause when I add pure Win32 code within the MFC classes like CDialog, it force me to use the MFC function instead the pure Win32 one. For example, when I use the "GetRect(...)" function, it force me to use MFC "GetRect(...)" where the arguments are different from the Win32 one.

Call ::GetRect() instead, to make it unambiguous to intellisense.

GetActiveWindow

misha_grewal26-Dec-03 23:10

misha_grewal

26-Dec-03 23:10

GetActiveWindow returns the active window - be it system or the current running program window.

HANDLE h = GetActiveWindow();
///show some other dialog
mydlg->DoModal;
delete mydlg;
SetForeGroundWindow(h);

So whenever there is a system window like error message or battery information, GetActiveWindow returns the handle of this window. The SetForeGroundwindow method then takes the user to the Start menu rather than the previous program window.
Any ideas how to remove this defect. What other method can i use instead of GEtActiveWindow? Can i get window information like is it a system window or my program window. Would GetWindow help in this case?

Thanks...

file reading problem - pcoket pc

Hi I'm writing my file successfulling to my pocket pc, with all the data,
but when i try and read the file with something simple

<br />
<br />
FILE *stream;<br />
BYTE list[25];<br />
if( (stream = fopen( "encrypt.txt", "r+t" )) != NULL )<br />
{<br />
     /* Attempt to read in 25 characters */<br />
	int numread = fread( list, sizeof( char ), 25, stream );<br />
	fclose( stream );<br />
}<br />
	<br />

or even

<br />
CFile f;<br />
if( !f.Open( "encrypt.txt", CFile::modeRead ) ) <br />
{<br />
	AfxMessageBox(_T("Unable to open the database"));<br />
	EndDialog(0);<br />
	return FALSE;<br />
}<br />
int nSize = f.GetLength();<br />
char * pBuf = new char[nSize];<br />
int nRead = f.Read(pBuf,nSize);<br />
	<br />

I only get 1 character (the very first) read from the file.
What am i missing?
regards
Bryce
