modification can be performed at the time of the cross-version upgrade. For example, the user is currently upgrading from the second version of the program to the third version of the program, then the logic in case 2 will be executed. If the user is directly from the first version of the program to upgrade to the third version of the

No intention of discovering the use of map files during csdn wandering, and recording them for your learning. K5z flat Software ParkK5z flat Software ParkIdentify the source code error line through the crash address only k5z flat Software ParkI believe many people have encountered the "Access XXXXX" address error during code execution. Under normal circumstances, we cannot trace the error code lines based on the error information. We can only view the

Using producer and consumer patterns in concurrent programming can solve most concurrency problems. This mode improves the overall processing speed of the program by balancing the productivity of the production line and the consuming thread.Using producer and consumer patterns in concurrent programming can solve most concurrency problems.

In Android, in addition to starting a program from the interface, you can start the program from the command line, using the command-line tool AM. Copy Code code as follows: usage:am [subcommand] [options] Start an activity:am start [-d]-d:enable debugging Send a broadcast intent:am broadcast Start

(Reprinted) As a programmer, what do we worry most about? Is memory leakage? Is the interface hard to see ?...... Wrong! I believe that there will be no objection in my opinion-that is, the program has crashed! "This program has performed illegal operations and is about to be closed. Please contact your software supplier .", Well, I am afraid this M $ famous saying is something programmers are most worrie

Many times, we need to have the program support command-line startup, this time we need a command-line parser, because the. Net BCL does not have a built-in command-line parsing library, so we need to implement one ourselves. For simple parameters, it is also good to write a string comparison function to parse the args

Tested personally: VS6, VS2005, VS2010, etc. the IDE does not support the delivery of multiple command-line arguments (estimated 2003, 2008 also), but it is possible to code through the WinMain main function command-line arguments PSTR szCmdLine (MFC is M_ lpCmdLine) receives a string with a carriage return line feed. With IDE debugging to set parameters, vs onl
