C# help!

[Guest alhabibam]

Hi all,

I am developing a smartphone application using C# and I need some experts to help me by answering the following questions:

1. How can the data be stored in the mobile. For example if the user of the application entered some data, and I want to save them what shoul I do?

2. How can I insert a time filed in the interface?

3. If my application works like an alarm clock, how can I set triggers to be fired at specified time?

4. What APIs should I use to change the profile settings of the mobile? For example to change the profile to silent!!

5. Where can I find good code samples for smartphone developed in C#?

--If you can answer any of the questions, please don't hesitate to reply!!

Thanks.

1. How can the data be stored in the mobile. For example if the user of the application entered some data, and I want to save them what shoul I do?

If the datastructures are getting a bit more complex, I would advice using either dataset serialization (DataSet.WriteXML), or using custom serialization with OpenNETCF.

2. How can I insert a time filed in the interface?

Write a your own custom control, or use the amazing OpenNETCF DateTimePicker control.

3. If my application works like an alarm clock, how can I set triggers to be fired at specified time?

Read up on the Timer and TimeSpan classes.

4. What APIs should I use to change the profile settings of the mobile? For example to change the profile to silent!!

Check out the SDK Help file that comes with the Microsoft "Smartphone 2003 SDK".

5. Where can I find good code samples for smartphone developed in C#?

Thank you for your reply.

That was very helpful for me, but If you can include some code samples for data storage, and for creating a custom control will be very helpfull.

I appreciate your efforts.

Thanks.
