问题 It's very very frustrating. I am using a singleton class (popup, which means it doesn't forget the last used variables) which contains a datagrid. I am making various columns visible/invisible, setting the widths and headers in accordance to data received from a database call. Everything works fine except that when I put the breakpoints before and after the point where I change width of columns, I do not see the change in width of datagrid at all! Instead I see some values totally out of sync

问题 I have the following problem. In my application I have several modules and each of them have components CollapsableTitleWindow (extends Panel). After opening the window it is added to the container which is in the main application (CollapsableTitleWindowContainer). In these windows you can open another window (and so on).

问题 I need to play three musical tracks one after the other in a circle. It is necessary that its are not loaded again and were in the cache. I use this code. Everything works fine on localhost, but only works after restart the app on the server. And wrong to re-download tracks every time. public function musicOn():void{ if (sndStart == 'true'){ req = new URLRequest("media/" + track + ".mp3"); snd.load(req); channel = snd.play(); channel.addEventListener(Event.SOUND_COMPLETE, onPlaybackComplete);

问题 I'm having some troubles matching the value returned from RSA signing a Base64 SHA1 hash in the actionscript as3crypto library with the result returned in c#. I'm passing in a Base64 hash decoded as a byte array to the sign() function provided in as3crypto and base64 encoding the result. However, this result never matches the returned result from a c# function which performs the same task. Does it matter that the function takes in and returns hex even though it works at the byte array level?
