Finding the version

Flash ActionScript 3.0 components have a version property that you can display if you need to provide it to Adobe Technical Support or you need to know what version of the component you are using.

To display the version number for a user interface component:

Create a new Flash file (ActionScript 3.0) document.
Drag the component to the Stage and give it an instance name. For example, drag a ComboBox to the Stage and call it aCb.
Press the F9 key or select the Windows > Actions to open the Actions panel.
Click Frame 1 on the main timeline and add the following code to the Actions panel.
```
trace(aCb.version);
```
The version number, similar to the one in the following illustration, should appear in the Output panel.

For the FLVPlayback and FLVPlaybackCaptioning components, you must refer to the class name rather than the instance name because the version number is stored in a class constant.

To display the version number for the FLVPlayback and FLVPlaybackCaptioning components:

Create a new Flash file (ActionScript 3.0) document.
Drag the FLVPlayback and FLVPlaybackCaptioning components into the Library panel.
Press the F9 key or select the Windows > Actions to open the Actions panel.
Click Frame 1 on the main timeline and add the following code to the Actions panel.
```
import fl.video.*;
trace("FLVPlayback.VERSION: " + FLVPlayback.VERSION);
trace("FLVPLaybackCaptioning.VERSION: " + FLVPlaybackCaptioning.VERSION);
```
The version numbers, similar to the ones in the following illustration, should appear in the Output panel.
