Hello

It seems that the GprsCoverage Property do not reflect if the GPRS connection is active

if (Convert.ToBoolean(SystemState.GetValue(SystemProperty.PhoneGprsCoverage)))
{
   bool GPRSOK=true;
}

Is there any way to insure that the connection is active ant activate it if not ?

Thankk for your help

Use the ConnectionManager API.
For C#, you will either have to P/Invoke these APIs or use OpenNetCF[^].

Use the SetSystemPowerState API.

SetSystemPowerState( L"Suspend", 0, 0 );
SetSystemPowerState( _T( "On" ), 0, 0 );

The mouse events pass you a MouseEventArgs (or derived) object to your handler delegate. MouseEventArgs has a GetPosition() method that will give you the coordinates relative to the UIElement of your choice.

For showing images I would start with the Image class.

hi all,

i m creating a html file in my application.

is there any classes in Cocoa for simple file encryption/decryption? I just need something I can point at a file on disk and do simple encryption without a password or key and then decode it later. Doesn't have to be fancy or even all that secure - just something simple and easy to use.

please help me for this.

if possible please provide me any example.

thanks in advance.

Cross Platform Mobile Development

I have developed a C# app that uses compact .NET and runs on Windows Mobile. Unfortunately, I seem to be the only person on planet earth still running a Windows Mobile phone.

So my question is if you wanted to develop an app to run on most of the popular mobile devices about, what language and IDE would you use?

I note that Android uses Java and iPhone uses Objective C. I have also found something by Novell (I think) called Mono that is some sort of emulator that runs .NET on Androids. So with Mono maybe C#.NET is the answer.

It seems to me that some means of platform independence here would be highly desirable

Hi,
so if you want to develop only for android and windows mobile phone i think c# is a good choice. As you pointed out there is a port of the popular mono for android, so you can run c# apps on both phones.

Unfortunately there are some more phones, that cannot run c# apps, like Iphone, Palm or Blackberry. There are some frameworks on the web, which help to create "html5 web application" - you write html and javascript code and the framework will compile the source for all phones that are supported. One of them is phonegap, supporting Iphone, Blackberry, Android, Windows Mobile, Palm and Symbian as far as i know. For some of them it gives even access to the native functions and libraries.

So, i think if you want to get the most of each phone and access all native functions you have to develop the application in the phones programming language, as there are c#, java and objective c.

Windows CE 6: Problems with IHTMLDocument2 and Scripts.

Hello,
I've got a program written in C++. It was working fine on former versions of Windows CE but now I've got a probleam that the the browser windows I'm using inside that application didn't execute any scripts anymore.
The strange thing is that if I load the url with the IE on that device all is working fine.
when the url is loaded I download the content into a screen:

if (dStreamMem != NULL)
{
    GlobalFree(dStreamMem);
}

RELEASE(dStream);

//Create stream
dStreamMem = GlobalAlloc(GMEM_MOVEABLE | GMEM_NODISCARD,size - (content - dBuffer) + additionalHTMLLen);
BYTE* dStreamMemBuf = (BYTE*)GlobalLock(dStreamMem);


memcpy(dStreamMemBuf,content,size - (content - dBuffer));
GlobalUnlock(dStreamMem);

if (FAILED(CreateStreamOnHGlobal(dStreamMem,false,&dStream)))
{
    LOGTAG(Error_Download_CreateStreamOnHGlobal_Failed);
}

then I load the stream in a different method and try to display it in the browser window of my application

IPersistStreamInit* persistStream = NULL;
//Get document object
if (FAILED(pBrowser->get_Document(&dDisp)))
{
    LOGTAG(Error_ShowPage_pBrowser_get_Document_Failed);
    goto CLEANUP;
}

if (FAILED(dDisp->QueryInterface(IID_IHTMLDocument2,(VOID**)&doc)))
{
    LOGTAG(Error_ShowPage_dDisp_QueryInterface_Failed);
    goto CLEANUP;
}

if (FAILED(doc->QueryInterface(IID_IPersistStreamInit,(void**)&persistStream)))
{
    LOGTAG(Error_ShowPage_doc_QueryInterface_Failed);
    goto CLEANUP;
}
if (FAILED(persistStream->Load(dStream)))
{
    LOG('I', "Load Stream failed!\r\n");
    LOGTAG(Error_ShowPage_persistStream_Load_Failed);
    ret = FALSE;
    goto CLEANUP;
}

The page is displayed in HTML without any errors (or at least it seems so) but when I press a button there nothing is happen.
Anyone an idea what could cause such a behaviour?

Use CeSetUserNotification to activate your program at a particular time of day.

Then, use TAPI to turn the cellular radio off.

Windows Phone 7?

If so...

WP7 uses a Silverlight .NET runtime ~equivalent to Silverlight 3.0. You'll need to learn Silverlight programming.

This is the forum for all the Mobile OSes. We don't have separate forums for iOS, Android or WP7. That does not mean that all of them are dying.

Hi,

I am working for a digital publishers and we are planning to develop an iphone app for one of our magazines. At the moment we are looking for all the options available.

1.) - We code ourselves using XCode IDE, Objective C programming language.

2.) Adobe has launched a product called Digital Publishing Suite but there is some monthly cost associated with it. (Not sure what the cost is at the moment..) and they only do it for ipad and not for iphone. Where as we are looking for a solution for both ipad and iphone.

3.) Looked at another company that provide similar solution like adobe i.e. Alligator Digital Magazine and the minimum they cost is $300 per month for 50GB online storage and it goes upto $2600 per month for 200GB online storage. + £100 per hour support rates.

So am just wondering, what would be the best option for us in longer run. If we develop our own app inhouse - i think it will cost us quite less in longer run. Not sure if there are any cost involved other than hosting charges if we do it in house development.

Please feel free to share your views. If you have the resources - would you prefer developing the app or using third party tool to develop quick and easy app which might cost more in the longer run with monthly payment.

Thanks a lot.

I've done it before, and the results are not pretty. You can compile programs and you can deploy them to a real device, but you cannot debug them on XP. As already mentioned this isn't supported.
