The flash window can be shown in four different scale modes. You can decide whether it should be resized to fullscreen or stay at design size. Just enter in the first frame one line of action script:

AS2: Stage.scaleMode = "exactFit";

AS3: stage.scaleMode = StageScaleMode.EXACT_FIT;

Here are the four different modes explained: AS2 scaleMode property and AS3 scaleMode property.

No Scaling

To show the flash window in the original size a.k.a. ‘No Scaling’, add following action script code:

Stage.scaleMode = "noScale";

function getSize(dummy1:String,dummy2:String,dummy3:String): String
   return loaderInfo.width+"x"+loaderInfo.height;
stage.scaleMode = StageScaleMode.NO_SCALE;

Command Line Options

Returns the value command line option from /key <value>

Returns all command line options

Reading & Writing any file

Writes ‘content’ into the file ‘text.txt’

Returns the content of ‘text.txt’, this is only available in AS3

Sets read_content.text to the content of ‘text.txt’, only required for AS2

file_read_text and file_write_text will replace new lines with the windows version of line feeds and store the text as UTF-8.

Search for files

This will return the matching files and folder in the format <name>|<size>;
If the pattern starts with the @ sign, all sub folders are searched, otherwise only the specified folder is searched.
You can use environment variables like %APPDATA%

Returns all files and folders matching the given pattern, this is only available in AS3

Sets result.text to all files and folders matching the given pattern, only required for AS2

Registry Access

Writes ‘content’ into the registry at ‘key’. ‘key’ can be for example: HKEY_CURRENT_USER\path\key. Prepend ‘key’ with DWORD\ to force REG_DWORD access instead of REG_SZ.

Returns the content of ‘key’, this is only available in AS3

Sets read_content.text to the content of ‘key’, only required for AS2

Flash Player

The generated executable requires a installed Adobe Flash player. In case of too old or non existing Adobe Flash player, the executable will show a message box and ask for installation of the Adobe Flash player.

If you want to bundle the Adobe Flash player with the exeuctable, copy the 32 bit version of the Flash.ocx as Helper.ocx into the installation directory (where FlashBuilder.exe is located). The FlashBuilder application will detect this and include the Helper.ocx into the generated executable.
This will allow the generated executable to run on computers, even if there is no installed Adobe Flash player.

Assets Folder

If the option is enabled, all files from the ‘assets’ folder are included in the generated executable. You can call ExternalInterface.call("getAssetsFolder"); to get the temporary folder where all files are extracted.

If a file called ‘flashnotify.bat’ is present, it is called with ‘start’ or ‘end’ and the application file name as command line parameter.

Mouse Click Events

function middleButtonPressed(sData:String,sData2:String,sData3:String):Void
This function is called, if the middle mouse button is pressed

function showContextMenu(sData:String,sData2:String,sData3:String):Void
This function is instead called, if the right mouse button click context menu is disabled


You can store and read key/value pairs in the registry or in an ini file.

The ini file will be used if the key starts with an @ sign:

Otherwise the registry will be used:

Shell Tray Icon

You can show and hide an icon in the shell tray bar:

Animated cursor support

If a ‘Cursor.ani’ file is located in the same folder as the .SWF file, this file will be included in the FlashPlayer.exe and will be used as cursor.

Transparent Text Drawing Issues

To prevent that text in dynamic TextField controls is drawn transparently, add any Filter to the object. For example ‘Adjust Color’ with zero values. So no change in style will happen but the text is shown correctly.
Alternatively you can select in the FlashBuilder ‘Transparent Background with transparent text fix’.
