Use flex builder 3 to compile Flash Player 10 applications

At present, we can use flash cs4 to directly compile Flash Player 10 applications, but for developers, flex builder 3 compilation environment is more familiar. Currently, flex builder 3.02 supports Flash Player 10. However, during compilation, the default supported Flash Player version is 9.0.124, we only need to manually change the version of the target browser to use the new features of Flash Player 10. The following describes three manual configuration methods.

• Project> Properties> flex compiler: Set the additional compiler parameter-target-player = 10.0.12.36
• In the. actionscriptproperties project configuration file, set the value of additionalcompilerarguments to-target-player = 10.0.12.36 or change htmlplayerversion to "10.0.12.36"
• Set the value of the target-player element in the flex-config.xml to 10.0.12.36

Now our flex builder supports the new Flash Player 10 API.
