Q: How to bypass all warning.
A: Use compiler option - /W, /w(Set Warning Level.)
Warning Level Description
/w Turns off all warning messages. Use this option when you compile
programs that deliberately include questionable statements. The /w
option applies to the remainder of the command line, or applies until
the next occurrence of a /w option on the command line. /W and /W0
are the same as /w.
/W1 Default. Displays severe warning messages.
/W2 Displays an intermediate level of warning messages. Level 2 includes
warnings such as the following:
• Use of functions with no declared return type
• Failure to put return statements in functions with non-void
return types
• Data conversions that would cause loss of data or precision
/W3 Displays a less severe level of warning messages, including warnings
about function calls that precede their function prototypes in the source
code.
/W4 Displays the least severe level of warning messages, including
warnings about the use of non-ANSI features and extended keywords.
/WX Treats all warnings as errors. If there are any warning messages, the
compiler generates an error message, and continues compilation.

Q: How to auto run the program when card plug in.
A:
1. Use the API to build up a execute file.
#include
#include
#include
void wmain(void)
{
CeRunAppAtEvent(_T("\\windows\\touch.exe"),
NOTIFICATION_EVENT_DEVICE_CHANGE);
}
Parameter one is launch APP and two is Card detect even.
2. Launch the execute file to notify the information to OS when launch the
notified APP after OS boot up.
3. OS will auto run the APP after card plug in.
ps. The way can’t launch APP in Card because the program will launch APP
when card plug in before mount.
