From your question it would seem that you are at a very early stage in your project; have you already looked here[^]?
It's time for a new signature.

Hello everyone!
I'm new on mobile development, so be gentle with me. I need some information about how to create a serial communication, like the way arduino is connected to computer, a serial protocol. I want to create an applet to communicate with a C# application, for data exchange.
|

|

It's hard to answer that without knowing about the hardware you are using. Are you using a Windoiws Mobile device? Some other Windows CE device? Perhaps a .Net Microframework device?
|

I'm using a Sony Ericsson w910i (not a smartphone). The purpose is to create a java applet for my phone, that enables it to comunicate with my laptop, through bluetooth. I searched online about this type of connection, but found nothing.
|
|
|
|
|
When I run Windows Explorer, I can search the phone and add and remove and move around files and such on its SD card. When I try to do it programmatically, however, it appears that there is no way to do it. Is there a way to tell a program to create a file or copy a file to a docked Windows Mobile 6.1 device from a program running on the Windows 7 desktop?

I have a class that I need to convert to a byte array for a Windows Mobile device. The byte array is sent using ssl to a server, which needs to rebuild the class. I have used BinaryFormatter on a PC client that worked great. However I can't use that with the compact framework. This is the code I am currently trying to use but its giving me the error message "Type 'PackageTrans' cannot be marshaled as an unmanaged structure; no meaningful size or offset can be computed.".
public byte[] ClassToBytearray(object obj)
{
int Length = Marshal.SizeOf(obj); <----------This is where I get the error.
byte[] bytearray = new byte[Length];
IntPtr ptr = Marshal.AllocHGlobal(Length);
Marshal.StructureToPtr(obj, ptr, false);
Marshal.Copy(ptr, bytearray, 0, Length);
Marshal.FreeHGlobal(ptr);
return bytearray;
}
This is my first time using Marshal. Why wouldn't a meaningful size or offset be computed? What is it that I am missing? Is there a different way I should be doing this? Any and all help would be greatly appreciated.
Thanks

Look into serialization, there are many options -> Binary, xml, soap, etc.

Hi Friends,
I am developing a Windows Mobile application using 6.0 professional SDK.
Here I am consuming a web service which is hosted on HTTPS.
I am able to add the web reference successfully but when I call a method of the service using proxy it throws following exception.
"Could not establish trust relationship with remote server."
The same scenario works fine if I test it with a desktop windows application. I am able to call the method successfully and I receive the response too, but I dont know why it is not working with Windows Mobile.
I am able to browse the websites from the mobile browser so there is no issue about the connection.
Please help me soon friends I m running out of time...I have search all over the world during last 2 days but could not find any satisfactory and working solution.
Thank you all in advance.
Thanks and Regards,
Chetan Ranpariya

The first thing I would check is the date and time on your Windows Phone. It it is wrong then SSL authentication will fail.

Hi Joel,
Thanks for the reply.
I tried the tip you mentioned. I am currently running the application on device emulators.
I changed the date time information of the emulator to my system date time but it didn't work.
The web service I m consuming is in different timezone, and I tried to change the emulator datetime information to that timezone too, but that also didn't help me.
I event asked the service providers but according to them there is nothing changed from their side except the service url which I am currently using.
If I refer the same service url in a windows desktop application, everything works fine.
I am really stuck. Please help me.
Thanks and Regards,
Chetan Ranpariya

Dude! I tried this (setting the correct date/time) out of desperation after continually having a "Could not establish trust relationship with remote server" error message and it flippin' worked. Thanks for the tip--why can't these error messages give a little more information????

Hi friends,
Finally I found the solution of this problem.
I had to create a class which implemented ICertificatePolicy interface as following.
public class AlwaysTrustedCertificatePolicy : ICertificatePolicy
{
#region ICertificatePolicy Members
public bool CheckValidationResult(ServicePoint srvPoint,
System.Security.Cryptography.X509Certificates.X509Certificate certificate,
WebRequest request,
int certificateProblem)
{
return true;
}
#endregion
}
And before calling the first ever method of service I created an instance of this class and assign it to "CertificatePolicy" of "ServicePointManager" class.
ICertificatePolicy certificatePolicy = new new AlwaysTrustedCertificatePolicy();
ServicePointManager.CertificatePolicy = certificatePolicy;
var serviceClient = new ServiceClient();
serviceClient.Login(username, password);
This worked for me very well... but this is I guess work around not the proper solution.
If any body finds the solution please post.
Thanks and Regards,
Chetan Ranpariya

If I were to develop a 3D app that I wanted to port to the 3 major touchscreen mobile operating systems, what language should I choose so that it's easily portable?
I've developed many apps on WinMo, and have just built a hello world app for Android. Is there anything that will work on all 3 platforms with minimal modification?
Thanks!

Looks like OpenGL ES is an option.
