Hi All. One common problem many would have got while developing web applications in Adobe Flex is, SWF files not getting displayed after the project is exported. Don’t panic, it’s very simple to kick away that problem. Just follow these steps.
NOTE: Every MXML file created in a Flex project will be compiled into a SWF file and such SWF files will get displayed without any problem after the project is exported. Here we are dealing with external SWF files that are loaded using SWFLoader Component.
After creating a project in Flex Builder(Let me assume that, this project uses SWFLoader component which loads external SWF files here), do the following steps.
1) Right click on the project folder in the Flex Navigator tab and in the menu that appears, click Properties .
2) Click Flex Compiler in the Properties Pop Up Window.
3) Type -use-network=false in Additional compiler arguments text input box.
4) Click Apply and then Ok.
SCREENSHOTS:
Please click any image to enlarge it.
STEP 1 - Right click on project folder - Click Properties
STEP 2 - Click Flex Compiler in the Properties Pop Up Window
STEP 3 - Type -use-network=false in Additional compiler arguments text input box
STEP 4 - Click Apply and then Ok
