flex3

问题 We are using as3Crypto library in my project. We have downloaded the code, modified a bit and started using it. Initially we have included the complete code as the part of the project. Now we are trying to compile it as Separate Library file(.swc).

Do I need to buy Flex Builder Professional to compile the project, or will Standard work? On a related side-note, the Adobe website is brutal. I was going to use Eclipse with the SDK but the increased setup time and lack of code completion makes it not a contender in my situation. 回答1: If code completion and ease of setup are primary concerns, then I
