I developed a mobile phone home location software for smartphone.

I developed it myself using. net. Welcome.

Functions:

You can search for a region by ID card (at least 15 characters), mobile phone number (at least 7 characters), area number (any digit, no preceding value), and zip code (any digit, check the zip code and area code by city name and province name. The database is not very up-to-date. I hope you will understand and provide the database.

Smartphone2003 comes with a. Net runtime environment. Just copy the smartcodecontents In the compressed package to your mobile phone and create a shortcut for smartcode.exe.

If it cannot run properly, install netcf. Phone. wce4.armv4. Cab

When developing technical feasibility studies, you are prepared to use dataset serialized XML to save data. However, the size of data files is 7 MB, which is obviously unrealistic. Later, I planned to use esql. As a result, on the win platform, I did not respond to the 3000 pieces of data inserted.

Later, we used opennetcf. Data. CSV. csvdataadapter. But this is to load all a CSV file into a datatable, which is definitely a hell of a cell phone's memory.

Finally, I modified the csvdataadapter and added the filter mechanism to load only qualified data to the able. In this way, the performance is better.

I will try to merge my modifications to the csvdataadapter into the CSV file of opennetcf later.
