Compile the Windows phone7 program and summarize the problems solved.

1. How can I get the phone number of the Windows phone7 host?

This cannot be obtained. It is said that the phone number is the information of the communication service provider, and WP7 mobile phones cannot be obtained. But why can some low-end mobile phones get this number?

2. Determine whether the phone number can be reached?

This cannot be done either, because

Phonecalltask = new phonecalltask ();
Phonecalltask. phonenumber = phone;
Phonecalltask. displayname = Name;
Phonecalltask. Show (); no return value. If other API methods are provided by Ms later, it should be possible. WP7 itself can certainly know the call records.

3. Are GSP positioning inaccurate? Is the location different from the actual location?

It is said that there is an offset in the positioning position due to policy reasons, but the Positioning Software in China is very accurate. Do they add an offset? Or is the current WP7 not released in China or localized? I don't know.

4. How can I not display all the widgets? Is the content of one item loaded?

This problem cannot be solved. Is there a better solution? My solution is to load the problem when pivotitem is selected, and write the pivot_selectionchanged event at this time, determine the specified titem in this event and load the content in the specified titem.

5. What should I do if the WP7 software is too big?

The maximum size of WP7 software is 25 MB or 400 mb. What should I do if the size is too large? Of course, I don't have any software to limit the size. But what should I do? Some people say that cloud pushing should be used to push hundreds of megabytes of data.

 

when you think about other problems, if you can solve them in the future, I will update the blog. .
