Flex log management and flex log management
There are two debugging methods in Flex:
First, use the trace () function for debugging in the flex builder;
Second, use the logTarget class and the following code:
// Create a target.Var logTarget: TraceTarget = new TraceTarget ();// Log only messages for the classes in
In Flex, use single-choice buttons to switch the horizontal and vertical coordinates and descriptions of the column chart, and use the flex column chart.
1. Problem Description
A group of single-choice buttons can be divided into weeks and months. Select "Week". The horizontal coordinate of the bar chart shows the Week, and the vertical coordinate shows the number of people. Select "month" and the horizonta

With the advent of the Flex development framework, developers can finally create the rich web-based, platform-independent applications they 've always wanted. such applications typically require data integration, which is necessary for any use case that requires keeping track of users, conducting authentication, or saving a user's data. you can use local data storage, but without the persistence and centralization brought by client-server communicatio
PHP communicates with Flex through AMF, and I debug the discovery that, as long as there is a date () function, Flex returns an error
a.php
Class Edit_img{ function Gmtime () { $temp = Date (' Z '); return $temp; }
}
?>
This PHP communicates with the flex through AMF, and I debug to find out that as long as there is a date () function,
First, the release target is the independent Flashplayer player.Scaling and alignment modes are similar to Flex 4 desktop projects in many places.Specify the window content area (stage) size for flashplayer by using [SWF (WIDTH=XXX,HEIGHT=XXX)] metadata in Fx:metadata, or by adding-default-size xxx xxx to the compiler parameter. The default size of the stage is still 500x375.When ScaleMode is Noscale, the stage size and application size change as the

Believe it or not, my first flex job had nothing to do with even 1% of rich Internet application. It wasPrint multiple pages in flex.
I know what you are thinking right now. Why shoshould I care printing in flex? Is flex supposed to be used for creating cool stuffs rather than this kind of low-level system function?
After recent speculation, Flex is still very useful and solves the difficulties that have plagued my web development front-end for a long time. Its AMF communication protocol uses binary stream to transmit data based on HTTP, high efficiency. Combined with blazeds and Ro, It is very convenient to Implement Asynchronous HTTP Communication Between the frontend and the backend. The standard port 80 is nice. The only unpleasant thing is that it takes some
When I did something yesterday, I found that flex and Java could not communicate well with remoteobject. I thought there was a problem with the endpoint path, but no problem was found after careful troubleshooting. "404" error always prompted:
Later, I checked the error message output on the console and found that struts2 was integrated. Therefore, struts2 blocked the request:
There is no Action mapped for namespace/messagebroker and action name
Flex uploads files and flex uploads
I wrote a jsp page using ajaxFileUpload to upload files a few days ago. Now I share the flex upload page as well:
Front-end page
As:
Var file: FileReference = fileList. getItemAt (I) as FileReference; var request: URLRequest = new URLRequest ("s/upload/uploadFile"); request. data = new URLVariables (); request. data. orderRed
Real Flex pages. One page can be reused multiple times and multiple flex pages can be reused.
After the check box is added to the datagrid In Flex, the number of rows on the last page is not enough, but the check box is still there. How can I remove it?
Well, you did. I tested it this time.Because there are not all the code, I copied the code above and deleted
SystemManager:
Systemmanager is the controller of the Flex application, which controls the application window, application instances, pop-ups, and cursors, and manages classes in the Applicationdomain. Systemmanager is the first class instantiated by Flashplayer, which stores the size and position information of the main window, preserving its subcomponents, such as the traces of a floating pop-up window and modal windows. Embedded fonts, styles, and

After learning the flash event mechanism, we began to learn three communication methods in flex and Java. FLEX can communicate with Java in three ways:
● Flex accesses Java common classes using the remoteobject method, which is also the most commonly used method.
● Flex uses httpservice to access Java Server classes
Today, the third method of communication between flex and Java is finally completed. I didn't figure it out because I don't know how to create a WebService. The free weather forecast service is used on the Internet. All right, you just want to learn this communication style for weather forecast, but I am not sure. Fortunately, we finally got it out today.
We know that flex and Java have three communication
