Sending SMS text

There seems to be very few real working examples for Sending / Receiving SMS
text messages using eVC++ 4.2 or for PocketPC.
I found Douglas Boling's SMSTalk in his book, but unfortunately the code
compiles but does not work.

Here is my abreviated SMS code that I'm using.

// try to open an SMS Handle
HREULST hr = HSmsOpen(SMS_MSGTYPE_TEXT, SMS_MODE_SEND, &smshHandle,
&hSmsEvent);

if (hr != ERROR_SUCCESS)
{
return hr; // never fails
}

// wait for SMS Event to become signaled
DWORD dwReturn = 0;
dwReturn = WaitForSingleObject( hSmsEvent, INFINITE ); // never fails

if(dwReturn == WAIT_ABANDONED || dwReturn == WAIT_TIMEOUT)
{
SmsClose(smshHandle);
return -1; // never fails
}

// Set up provider specific data
DWORD sof = sizeof(TEXT_PROVIDER_SPECIFIC_DATA);
memset(&tpsd, 0, sof);
tpsd.dwMessageOptions = PS_MESSAGE_OPTION_NONE;
tpsd.psMessageClass = PS_MESSAGE_CLASS0; // I also tried PS_MESSAGE_CLASS1
tpsd.psReplaceOption = PSRO_NONE;

// send the message
hr = SmsSendMessage (smshHandle,
NULL,
&smsDest,
NULL,
(PBYTE)pMsg, // the message
Len, // the message l;ength
(PBYTE) &tpsd,
sof, // Boling sets this to 12 tired it each way
does not change anything
SMSDE_OPTIMAL,
SMS_OPTION_DELIVERY_NONE,
&smsmidMessageID );

// at this point hr is always 0 which is S_OK which means success and never
fails

// Just to be sure, retrieve the status from the Service Center

memset(&smsStatusInfo, NULL, sizeof(SMS_STATUS_INFORMATION));
memset(tmpStr, NULL, sizeof(wchar_t) * STD_STR_LEN);

HRESULT sendResult = SmsGetMessageStatus(smshHandle, smsmidMessageID,
&smsStatusInfo, 5000); // always fails !

SmsClose (smshHandle);

-------------------------end
code-----------------------------------------------------------

SmsGetMessageStatus() always fails with this message "Unable to get Service
Center info: 0X80004005"

Sending the same message 10 times, SmsSendMessage() always returns S_OK the
message gets delivered ONCE (out of 10) but the NO text, just that a text
message came form my phone.!

My Questions:

Is there a real SMS example for PocketPC or SmartPhone using eVC++ ?

Any suggestions about problems with my version of this code are welcome.

Has anyone used .NET to SmartPhone 2003 Second Edition with the eVC++ 4.2
IDE ?

Is there a better way to do SMS on eVC++ 4.2 ?

Thanks

PS the 1 in 10 partial success rate is the same if I do or don't use
SmsGetMessageStatus() to check the status... it's as if SmsGetMessageStatus()
is not needed !

After a god nights sleep and checking my messages I found 20+ SMS text
messages waiting to be read !
Turns out (may be provider specific) sending text message to myself can take
a LONG time to before message arrives !
Testing my code with by sending SMS messages to another cell phone the
messages arrive in seconds to 1-2 minutes max.

However SmsGetMessageStatus() still fails everytime ! I sure would like to
get a ststus reoprt form the server.
Has anyone ever made SmsGetMessageStatus() work, if so what is the trick ?

Also Note! The problem I'm having with Douglas Boling's SMSTalk example is
the text input fields to not accept data, and the menus is hosed ! I feel
sure there is a simple solution for this also.

i use PS_MESSAGE_CLASS1, but other than that, it looks ok - how is 'Len'
calculated?
how is smsDest filled out? (can you include the first few digits of the
number you are using?
