IFormProviderEx Implementation Question
Please excuse me if I have selected the wrong group to post my question, I'm
happy to relocate somewhere more appropriate if necessary. I've searched
through the groups for other posts regarding my question and haven't found
the answer.
I'm attempting to customize some behavior of the Pocket Outlook (Inbox,
tmail.exe, what have you) by implementing IFormProviderEx. I'm specifically
interested in being able to provide custom icons for the messages in the
listview, which GetMsgStatusIconIndex would seem to allow for. I've followed
the sample code (<SDK>\Samples\CPP\Win32\Customform) and have it working in
my sandbox project. I can see that the CreateCompostForm and CreateReadForm
methods are being called at appropriate times, so I am confident my project
and registry settings are configured correctly. (I also see that my
FormFactoryEx function and my QueryInterface implementation method is being
called.)
The problem seems to be that GetMsgStatusIconIndex is not being called. No
icons are being displayed in the listview, which is reasonable given my
current progress. Any suggestions? =)
Also, once GetMsgStatusIconIndex is being called, I am a bit uncertain as to
where the icons need to be in order for my index result to be meaningful. I
haven't gotten to the point of attempting this, due to my first problem, but
my idea is to include my icons as resources in my DLL. If anyone has
information on this piece of the puzzle, I'd greatly appreciate that as well.
Thank you for your time, please let me know if I can provide further details.

ActiveSync Service Provider for custom contacts
Hi All,
Thanks all in advance..
I am writing a plugin for POOM, adding a custom field in Contacts. This came
as a success and could able to do it. But while syncing this additional
custom filed is not syncing with the desktop. So I started wtiting an
ActiveSync Service for this custom filed. I thought it might be easy. But
when I dig further a lot many problems arise.
I'm getting the custom field data by calling GetIDsFromNames() and
GetItemFromOidEx(). the oid's I'm getting from poomobj->get_oid().
I'm not able to get the required information for populating the OBJTYPEINFO
in GetObjTypeInfo().
The CEOID I'm getting in the ObjectNotify is not at all matching with the
oid's. I'm stuck up totally and couldn't able to move further.
Like to get the information how to implement this feature. Is it possible to
do this in WM 5.0? Appreciate for the valid reply. Will be good if aby one
can refer somebody who already did this..

setsockopt with paramter TCP_NODELAY does not work with WM5 device
My program works in such a way that I would benefit from the TCP_NODELAY
option. I read and understand why a developer might not want to
enable/disable this setting.
This code works on Windows but not on CE. On CE, if I set the value to 1
and read it back, then the value is 8. When using a network analyzer, I can
see that this setting has no effect on CE whereas it works perfectly on
Windows.
Any ideas?
int on=944; // any value but 1 or 0
int len = sizeof( on );
getsockopt( Socket, IPPROTO_TCP, TCP_NODELAY, (char *)&on, &len );
// on equals 0
on = 1;
setsockopt( Socket, IPPROTO_TCP, TCP_NODELAY, (char *)&on,
sizeof(on) );
int len = sizeof( on );
getsockopt( Socket, IPPROTO_TCP, TCP_NODELAY, (char *)&on, &len );

How the security policies work with pushmail
Hi All,
I have a couple of questions relating to the device security settings when
using Exchange Server pushmail.
Firstly, when are the security settings applied? Is it every time a sync is
done and a difference is found? If so what is the purpose of the refresh
settings time?
Secondly, what is the difference between the keys
HKLM\Comm\Security\Policy\LASSD\AE\{50C13377....
and
HKLM\Comm\Security\LASSD\AE\{50C13377....
As on my device the latter seems to be the one that defines the security
behaviour and they currently differ.
Thirdly, what AEFrequencyType value would allow me to have an inactivity
timeout, as well as lock the device on suspend?

Help: Question about TAPI and Modem.
Hi, everyone, have a nice day,
Sorry to bother you, but I have some question about the use of TAPI.
My work is to develop a CSD-trans app on PPC Phone Edition(WM 5
kernel), but actually the PDA is not bought yet: this is because my
project manager wanted to reduce the risk of our project and he told
me to develop an app using TAPI in windowsXP at first for testing, and
the test use TWO normal 56k modem(V.90 OR V.92) and TWO PCs instead of
the original TWO GSM Modem, one PDA and one PC. The TAPI is of ver2.0.
My question is:
1. In MSDN, I found that TAPI2.0 need UNIMODEM to work and the actual
modem must be "Hayes-compatible". I understand what's "Hayes-
compatible", but how can I judge whether a modem is "Hayes-
compatible" ? Is there some trade-mark or some verification mark or
something like this on the modem ? I think the RS232 56k modem must be
"Hayes-compatible", am I right ?
2. If I connect the RS232 modem to the PC, how can I make the TAPI to
use this modem OR how can the TAPI entity "discover" the modem ? Maybe
it's some confusing, let me explain more: when you need to use
TAPI ,firstly you may use lineInitialize() to get the total number of
TAPI supported device, then negotiate the version of TAPI and so on.
Before calling lineInitialize(), there must be some information of
modem devices stored at somewhere in the OS, then the lineInitialize()
function could be possible to return the information. If what I said
is right, how to make the TAPI entity to know there is a modem on the
commport ? So after calling lineInitialize() the TAPI entity will
found the special modem.
3. Is it possible to translate the app to Windows Mobile without much
work ? Is there no question if the normal modems are replaced by the
GSM modem (both use hayes AT set)?
Thanks your precious help ahead. ^_^

ActiveSync disconects other NDIS session
We develope MDTV application which recieves DVBH TV transmition and enables
video players to show the MDTV broadcast.
Our device driver acts as NDIS miniport which sends IP/UDP packets recieved
from the MDTV modem and put it in the device IP stack.
Out system works fine as long as the active sync is not working, but as the
device placed in the cradel, and active sync starts - no more UDP packets are
recieved although the driver itself keeps working as usual.
After the device is off the cradel, the player application can reopen a
socket and the packets keep coming.
Killing the ConnMgr process solves the problem, both active sync and MDTV
are working at the same time but this ofcourse can't be a solution for the
end user.
Any suggestions?

INF file entries :MajorVersion, MinorVersion?
The INF file used in building an installation of a Pocket PC program has a
section for writing registry keys such as:
HKLM,Software\Publisher\App\MajorVersion,0x00010001,1
HKLM,Software\Publisher\App\MinorVersion,0x00010001,0
I read somewhere that these entries are just for being a "Good Citizen" for the
benefit of the Windows CE Application Manager. Where can I find out the exact
function of these entries, and what the consequences would be if I left them out
of my INF file. When I release an upgrade with a different "internal" version
number, should I update this record of the version numbers too? And what is
that 0x00010001 all about?

Diagnosing a WMDC service provider error

Flight Mode On/Off Example Needed
I'm looking for a way to completely disable flight mode on a

>From everything I've read that involves using ExTAPI with
lineSetEquipmentState.
Kicking around in the internet is a Alex Feinman's TAPI wrapper (1.6)
but that does not seem to work at all on my device.
I've been looking at the Extapi example in the SDK which clues me in a
little bit in terms of calling the API but I am stuck trying to use P/
Invokes to get it working in managed C# code.
If anyone can point me in the direction of an example of what I'm

Formatting Information
I'm currently writing an app that has a lot of text based information,
but I'm having trouble figuring out how to display and format this text.
The text is supposed to be stored in a database and my app will read the
text from that database and then format it appropriately within the PDA.
This is the part I'm having trouble with - the fact that the text is
dynamic and my WindowsForm has to adapt to it. Say I have the following
(using HTML):
<h2>Some Title</h2>
<br>
<b>Sub title: </b>
<li>List item one</li>
<li>List item two</li>
<li>Sub list item two</li>
<li>List item three</li>
How can I format all of this information using standard WindowsForms
controls? Do I just build a bunch of Windows.Forms.Labels and drop the
text in? Would I be better off using real HTML (hosted on the PDA, not
web) and loading it into the WebBrowser control?
Thanks for any advice. Tag: update APs Tag: 121587

Services in WM5.0 - PLEASE, HELP!!!
Hi all,
I've got an application developed for PocketPC 2003 where a service
registered in HKEY_LOCAL_MACHINE\Services\ is loaded trough the function
ActivateService.
Now I have to translate and re-compile in VS2005 in order to execute
it on a Windows Mobile 5.0 device.
I've tryed using ActivateService, RegisterService and GetServiceHandle (even
it's deprecated since WM5.0) from setup.dll's Install_Init and Install_Exit
functions, but none of them work. In fact, none of the functions xxx_Init,
xxx_Open, etc. are being called.
The registry entry actually exists at the very moment I try any of those
functions but, as they always fail, the installation can not complete and
that registry entry disappears.
What else can I do?

localization
Hi,
My method for localizing app was to create seperate resource dll's, (dll
containing only resources, like dialog and string resource), then
dynamically load the correct resouce file during execution.
However, in my IDE, I can't even type cyrillic or chinese characters
(characters show up as ?) into the resource editor. Visual Studio doesn't
like unicode resource files either.
Currently, I'm loading my strings from XML file, but this doesn't work well.
For example, on SmartPhone, when you change the regional settings, the
language changes on your device immediately, and all (built-in) apps, and
not only that, even the names of applications (shortcuts) change!
Now, how does this work? I'm guessing the application has multiple string
table resources, each for a different code page, and OS selects the match
one? The resource editor only provides like 4 languages for your resource
files though, english, german, french, local and neutral I think..
Can someone tell me how built-in apps have their shortcut names localized to
whichever language the user selects?

File transfers between PC <> PocketPC
In an application I work on I will exchange some data files when the
Pocket PC is cradled. I will use RAPI from the desktop to copy files
between PPC and desktop. I know about other ways to exchange data like
using webservices, RDA etc but for this application it will be done by
simple file transfer using RAPI.
What happens is the following:
1) The desktop user start the the transfer process form the desktop
application.
2) PPC application need to export some of the data from the application
to a file. This is done either by the user pushing a transfer option in
the PPC application or a program is started on the PPC by using RAPI.
3) Desktop application copy the exported file from 2) to Dekstop and
process data
4) Desktop application copy files with data to be imported on the PPC
(possibly changed lookup tables)
5) PPC application import the new files into the database.
Step 5 could be done when the PPC application starts but the way this
application will be run it might be that the application is still
running.
If I choose the option to have the user start the transfer process then
it is pretty simple. Just wait for new files to be created then process
them and reload the datasets. However when two processes are running and
especially like this when on two separate computers it do raise some
possible problems. One computer does not know how when a process has
finished or not, but you can of course check for created files or having
the desktop computer to write to registry when process is finished or
something. But still, you need to be prepared for communication failures
etc.
I could probably also use the OpenNetCF filewatcher class to react when
new files to process have arrived on the PPC.
However, it would be best if the entire syncronization process could be
initiated from the desktop application without the user having to do
anything on the PPC. This should not be that hard to do, the desktop
program could launch a separate program on the PPC using RAPI which
exports and imports data. That seems like a clean and user friendly way
to do it.
However there is one problem that remains to be solved. If the PPC
application is still running I need to either close it or to use some
interprocess communication method (openNetCF?) to tell the application
to refresh datasets etc.
Questions:
1) Which method would you choose? Using a seperate program on PPC to
export/improt data or have the user start the transfer process in the
application? Any other betetr mthods to do this?
2) Can you show me some example shwo to use IPC with .NEt compact? Tag: update APs Tag: 121552
How to scroll a bitmap inside a today screen plugin?
Hello!
I have a problem creating a window with a vertical scroll bar.
Here's what I try to do:
HWND InitializeCustomItem(....
.......
g_hWnd = CreateWindow(appName, appName,
WS_VISIBLE | WS_CHILD | WS_VSCROLL,
CW_USEDEFAULT, CW_USEDEFAULT, 240, 0,
hwndParent, NULL, g_hInst, NULL) ;
SCROLLINFO si;
ZeroMemory(&si, sizeof(si));
si.cbSize = sizeof(si);
si.fMask = SIF_POS | SIF_PAGE | SIF_RANGE |
SIF_DISABLENOSCROLL;
si.nPos = 50;
si.nPage = 100;
si.nMin = 0;
si.nMax = appHeight;
SetScrollInfo(g_hWnd, SB_VERT, &si, TRUE);
. SetWindowLong(g_hWnd, GWL_WNDPROC, (LONG) WndProc);
....
}
LRESULT CALLBACK WndProc (HWND hwnd, UINT uimessage, WPARAM wParam,
LPARAM lParam)
{
.....
I set appHeight to 120 at the beginning.
In response to WM_TODAYCUSTOM_QUERYREFRESHCACHE , I set the ptli->cyp
to appHeight and return true (only once, of course, except for
resizes)
Later I create a bitmap:
case WM_CREATE:
{
if (!done_once) {
hBitmap = Test_NewDIBSection(appWidth, /
*appHeight*/480, (void **)
&bitmapa);
hDC = GetDC(hwnd);
hDCMem = CreateCompatibleDC(hDC);
hOldBitmap = (HBITMAP) SelectObject(hDCMem,
hBitmap);
done_once = true;
}
....
}
which works fine, however this bitmap is limited to the appHeight
size, while
I would very much like to scroll it down to see more. My window's
scroll bar appears, but it doesn't move, as if everything there is to
see is already shown. Also, the main today screen scroll bar appears
if necessary - and it works fine, scrolling my bitmap, but
unfortunately I need the internal scroll bar.
I understand that I can probably do it manually by responding to
WM_VSCROLL messages, but I doubt it would be as effective as a pro-
made scrolling. Does anybody know (probably most do :-( ), how can I
scroll my bitmap? I'm pretty sure that a smooth way to do it exists,
but I am simply missing something and have no idea, what it might be.
Thanks for any help!

0xe 0x24 0xc3 0x29 0x55 (Loop)
Does anyone see a similarity between the two sets of data? My Bluetooth
device appears to be shifting the data, but I don't recognize anything.
We have machines that send this data, and the Serial COM Port data is the
correct data. The Bluetooth data is coming in wrong, but it is consistent
and we receive the same number of bytes.
Is there a more appropriate message board I could address this question? Tag: update APs Tag: 121524
Serial port buffer check?
Greetings,
I'm porting some PalmOS serial port code to Windows Mobile/PocketPC. Is
there a PocketPC API available that will return the number of bytes of data
sitting in the serial port receive buffer? I'd like to know how many bytes
of data are sitting in the receive buffer before I try to read anything from
the buffer via ReadFile. On the PalmOS this is available via the
SrmReceiveCheck API. Any ideas?
Regards,

}
[DllImport("test.dll")]
private static extern int SetEmployeeData(ref Employee item);
// C++ Structure

Messaging application refresh
I have an application that runs in the background and can do things like
rename a MAPI folder. If the Messaging application is running when my
changes take place then the change will not be noticed until the application
is closed and then open again. Is there a way for me to tell the Messaging
application to refresh? I am hoping I can send the Messaging app a windows
message telling it to do so.

send email from a PocketPC app in VS2005
I just don't see the namespace 'System.Net'. I cannot believe
Microsoft has removed the ability of sending email from the
CompactFramework in VS 2005.....is this correct? If so, what are the
other alternatives?
I found an article on how to do it but with VS 2003, using
System.Web.Mail.
Please your response on this issue will be very appreciated.

setsockopt with paramter TCP_NODELAY does not work with WM5 device
My program works in such a way that I would benefit from the TCP_NODELAY
option. I read and understand why a developer might not want to
enable/disable this setting.
This code works on Windows but not on CE. On CE, if I set the value to 1
and read it back, then the value is 8. When using a network analyzer, I can
see that this setting has no effect on CE whereas it works perfectly on
Windows.
Any ideas?
int on=944; // any value but 1 or 0
int len = sizeof( on );
getsockopt( Socket, IPPROTO_TCP, TCP_NODELAY, (char *)&on, &len );
// on equals 0
on = 1;
setsockopt( Socket, IPPROTO_TCP, TCP_NODELAY, (char *)&on,
sizeof(on) );
int len = sizeof( on );
getsockopt( Socket, IPPROTO_TCP, TCP_NODELAY, (char *)&on, &len );
// on equals 1 on Windows, but it equals 8 on CE Tag: update APs Tag: 121497

calendar status
Hi,
Is there a more efficient way to check the current status of the calendar,
other than this:
IPOutlookItemCollection *pItems;
....
pItems->Find( szStartEndNow, (IDispatch**) &pAppt);
LONG bs;
pAppt->get_BusyStatus(&bs);
???
Is this status info perhaps available via registry or something?

Serializing XML Error
Hi,
I managed to write my array of my own custom class to XML file but when I
open the XML file, it will only store 4 lines of my class name as seen below.
But indeed there are 4 array items in my list collection. How come I cant see
the content of each of my custom class?
<?xml version="1.0" standalone="yes">
- <ArrayOfPERF_NR_QN_SCORE>
<PERF_NR_QN_SCORE />
<PERF_NR_QN_SCORE />
<PERF_NR_QN_SCORE />
<PERF_NR_QN_SCORE />
<ArrayOfPERF_NR_QN_SCORE>
My codes are as below:
----------------------this is how I call my SerializeXML
method-------------------------------------------
SerializeXml(typeof(NRQnScore), NRQnScoreCollection.ToArray());
------------------------------------------------------------------------------------------------------------------------------
public void SerializeXml(Type type, Object obj)
{
string XmlizedString = null;
MemoryStream memoryStream = new MemoryStream();
XmlSerializer xs = new XmlSerializer(type);
XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream,
Encoding.UTF8);
XmlSerializerNamespaces xsn = new XmlSerializerNamespaces();
xsn.Add(string.Empty, string.Empty);
xs.Serialize(xmlTextWriter, obj);
memoryStream.Position = 0;
XmlTextReader r = new XmlTextReader(memoryStream);
DataSet ds = new DataSet();
ds.ReadXml(r);
ds.WriteXml("PERF_NR_QN_SCORE.XML");
}
Pls advise.
Thanks

We wrote a simple utility to detect if the outlook event has changes. We
