I think that OpenNetCF has a named mutex implementation that can be used across different processes, but I am not sure about it.

The most common solution is to check if a Window is already present and not start a new process:

<br />
[DllImport("coredll.dll", EntryPoint="FindWindow")]<br />
private static extern IntPtr FindWindow(string lpClassName,string lpWindowName);<br />
<br />
[DllImport("coredll.dll")]<br />
private static extern int SetForegroundWindow(IntPtr hWnd);<br />
<br />
[MTAThread]<br />
static void Main(string [] args)<br />
{<br />
	string windowName = "MyForm";<br />
	<br />
	IntPtr window = FindWindow(windowName);<br />
	if (window == IntPtr.Zero)<br />
	{<br />
		Application.Run(new MainForm(windowName));<br />
	}<br />
	else<br />
	{<br />
		SetForegroundWindow(window);<br />
	}<br />
}<br />

This is not a bullet proof solution, but it works.

I would start with the kb if i were you, which is located here:

Otherwise, simply create a smart device project and code away.

Hey Ahzar!
First of all, the time it takes the page to load depends on the the server that you are calling the page from. So I hope that you have a good server machine doing the back end processing.
Secondly, are you using a lot of If Then statements, if yes then that could be another reason?
Third, I am not sure why you need 200 control (which I assume you are refering to HTML elements -> checkboxes) but see if you can break them down into sub pages, just like registering and filling out a form in thre steps. Remember that the Windows Mobiles are not as fast as a normal desktop system.
These are just the general hints that I can give you. It would make more sense if I knew exactly what is it that you are doing etc etc.

Feel free to email me if you need more help.

Regards,

Ali Rashid

Debugging Windows Mobile 6 over Wifi

27-Mar-08 2:27

I've got a application on my PDA which uses TCP/IP to communcicate to another application (on a PC).

If I have the PDA plugged in via USB, I can connect via the activesync "network", and the 2 apps play very nicely, and all is good.

If I connect over wireless, it works perfectly well... for a while. But at somepoint my app will freeze, and I have to reboot the PDA. I'm quite sure I have some sort of a bug, probably related to the connection connecting / disconnecting, or some memory leak.

But as it only manifests when running over wireless, I'd like to be able to debug it, and so far I'm failing to find a way to do that.

Can someone point me in the right direction? Even a "you're an idiot, haven't you looked at www.yyyy.com? It's all there..." message would be appreciated!

ps, using VC2008, and it's an MFC app.

Thanks,

Iain.

Hi for defining custom properties i am using the below code

const GUID guidRFC822 = {0x00020386, 0x0000, 0x0000, {0xC0, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x46} };
SPropValue structPropValue;
LPSPropTagArray lpPropTagArray = NULL;
// MAPINAMEID mnidNameID;
LPMAPINAMEID lpPropNames = NULL;

if (MAPIAllocateBuffer(sizeof(MAPINAMEID), (LPVOID*)&lpPropNames) != S_OK)
return 1;
structPropValue.Value.LPSZ = NULL;
lpPropNames->lpguid = (LPGUID)&guidRFC822;
lpPropNames->ulKind = MNID_STRING;
lpPropNames->Kind.lpwstrName = NULL;

lpPropNames->Kind.lpwstrName = _wcsdup(L"mmbisPending");

hRes = pMsg->GetIDsFromNames(1, &lpPropNames, MAPI_CREATE, &lpPropTagArray);

the value for hRes is 263040.

I am not able to figure out why this is not returning successfully. please help me

ATcommand GPRS PPP

Hi,

I have a console application written in C language using Visual Studio. The application will reside in a laptop to dial up to the Internet using a PDA phone. The connection between the laptop and the phone is set up using the Bluetooth Dial-up Profile.

I am able to make normal phone calls to a fixed house line and other mobile telephone number using the ATDT command. But I am unable to connect successfully to the ISP server through GPRS services. I am using the commands AT+CGDCONT=1,"IP","APN" and ATDT*99# (*99***1# is also tried). After issuing these 2 commands, I get a CONNECT response and then some unreadable characters appear. Then after a few lines of the unreadable characters, I get a NO CARRIER response.

I would like to find out is there any commands that I left out? Or is there another way for me to set up the PPP link between my laptop and the phone?

Thanks and regards,
PS

After CONNECT you get PPP frame, and you should communicate using PPP protocol after getting CONNECT.
I am looking for C# class to handle PPP, does anyone know where to find?

Question on Cell Phone Development vs. Pocket PC

I was trying to figure out how I would develop a game for my cell phone. But all the examples I have ran across so far focus on the Pocket PC, smart phone or Windows CE. What would I have to know or do to develop a game for my LG Verizon phone to play it? Would this be something I could do using the Mobile Development SDK?

Thanks for the time.

First you need to find out what OS and software platform your phone supports. LG makes Symbian/S60[^] and Windows based smartphones in addition to plain dumb phones.
Java ME[^] is probably the most widely supported phone software platform.
