C # mobile device development

1. How to get the file location:
String path = System. IO. Path. GetDirectoryName (System. Reflection. Assembly. GetExecutingAssembly (). GetName (). CodeBase );
Difference from WinForm Program Development: string Path = System. IO. Directory. GetCurrentDirectory ();

2. How to read text files: (use StreamReader)
Note that Unicode is supported in PPC, so the text file is first converted to Unicode encoding;
StreamReader myreader = new StreamReader (System. IO. Stream) File. OpenRead (filenameuser), System. Text. UnicodeEncoding. Unicode );
Differences from WinForm program development:
StreamReader myreader = new StreamReader (System. IO. Stream) File. OpenRead (filename), System. Text. Encoding. ASCII );

3. Notes for synchronizing data to PDA:
Microsoft ActiveSync, a synchronization software from Microsoft, is located at: Program Files // project name //........... so if you want to perform file operations
, Remember to synchronize the file to be operated to this directory;

4. the operation for reading XML from PDA is similar to that of WinForm, but some do not overwrite the XML file. Otherwise, the speed will be slow, mainly because of the memory and clock speed of PDA;

5. Interface Design: Because the screen of the PDA is not very large, we should arrange the screen properly when setting the interface. My consistent principle is: a main interface, provide connections or buttons for each interface on the main interface. do not perform operations such as Splitter on the PDA;

6. There are other issues to be aware!
