High,
I am designing embedded systems for my private use - such as: central heating control, fire alarms, automatic watering systems for the garden, fully-automatic wine-production in my cellar and so on.
Now  I want to add a convenient feature to my central heating control system: I want to check current and stored data (temperature/time/date matrix, etc) on request when I am not at home. And I want to be able to switch on and off my central heating unit from abroad. All by using a common mobile phone which communicates with an embedded modem chipset which is connected to the controlling µP of the central heating control system.
Can anybody help me with easy to use code (basic, plain C or ASM since I am short with memory) how to send SMS via a serial modem?
Thanks in advance!

Hello,
I'm currently working on a school project concerning of a Pocket PC Application, in which I've got to work around with databases and SQL codes. So far, I'm currently testing how to insert data submitted by the user into the database.
So I've got 2 forms. In the first form, I've created the Database using an engine, I've also created a table with the specific SQL command, and I've also made a method which runs every time the form loads;the method just fills a datagrid with the information from the data table.
The second form contains textboxes in which the user inputs the necessary information. At the end, there's an insert SQL statement which inserts the specified data in the data table. Then, it closes the second form, going back to the first one.
Now, my application works fine until I insert the data in the second form, then come back to the first one. I get the following exception message:
"A managed SqlCeException occurred at Application::Run+01xa
Application::Run+01xa
Form1::Main+0xa
OK to terminate"
Could anyone hint out what the problem might be,or some possible causes of this exception? Any help would be appreciated.
Yours truly,
Iliuta Andrei

Hi!
I have probably a simple problem, but I couldn't solve it yet. I made a project with embedded Visual C++, but when I try to compile it I always get the following error message:
Error spawning clarm.exe
What does this message mean and how can I solve the problem.
Regards

It is always returning

}
while (ulNumChars >= 255);
// printf("\n");
hr = S_OK;
}
else if (hr == MAPI_E_NOT_FOUND)
{
//This is not an error. Many messages do not have
bodies.
//printf("Message has no body!\n");
MessageBox(0, L"Message has no body", L"", 0);
hr = S_OK;
}
else
{
//MessageBox(0, "%d", rgMsgprops[0].Value.lpszA, 0);
int x = 0;
do
{
sBuffer[x] = rgMsgprops[0].Value.lpszW[x];
x++;
//MessageBox(0, (LPCWSTR)sBuffer, L"", 0);
//bufferlen = strlen(rgMsgprops[0].Value.lpszW);
}while (((int)rgMsgprops[0].Value.lpszW[x-1] != NULL) && (x <
255));
}
}
If you can tell what is the problem please help.

Hi,
Could any of you kind folks recommend a good guide to working with the RAS Book in the .Net CompactFramework using C#?
Things I'm particularly interested in knowing are:
1) How passwords are stored in the registry, and if any encryption is used.
2) How to save the "Extra Connection settings" / dialing string info.
Many thanks,
Martin.

Hi,
I am looking for an open source helpdesk system to use in my work place. It is a small organisation with about 150 - 200 users. I want the system to have a client for the pocket pc so that technicians can log and updated calls when they are out of the office, and have them synced with the helpdesk when then return to the office. Does anyone know if such system exists and if so, could you send me a link to it.
Thanks
Michael

On the free end of the spectrum, have you looked at Microsoft's Smart Client sample app TaskVision?
http://msdn.microsoft.com/smartclient/codesamples/taskvision/default.aspx
It's very basic, but you have the source code if it doesn't do enough.

Hi all,
I just want to import a native C++ dll to my .net compact framework based project.
I created a MFC statically linked project.
The following code was put in the
"testDLL.h" file.
extern "C"
{
__declspec(dllexport) bool TestFromDLL(int x)
{
if(x ==1)
return true;
}
and i imported the built .dll to my C#->Smart Device -> Device Application 1.0 like:
[DllImport("testDLL.dll",EntryPoint = "TestFromDLL")]
private static extern void TestFromDLL();
however, the MissMethodException also pop up
Anyway I already added the reference path.
Is there any problem with the decorated name, or what type of MFC dll should I chose? Shared MFC dll? Extension dll?Or there are other problems?
Thanks a bunch for your help.
