Adobe AIR: Transferring parameters to a local executable program

This article from: http://blog.everythingflex.com/2009/12/15/adobe-air-passing-arguments-into-native-executables/

I've discussed a section on the upcoming Flex 4 cookbook on air Basics for O ' Reilly, including about how to use local executable programs.

Here is an example of me:

First, I created a simple application that includes some local C code that takes only a few parameters and then outputs it to the screen. I compiled this C application into an executable program that can run on Mac, Windows, and Linux Ubuntu.

I then created an air application that includes the following code snippet. As shown below:

When I call the Callnativeapp () method, I identify a path to the Nativeapps directory that is packaged into my application. Then, depending on the operating system running the application, I specify the file variable to the appropriate executable program.

Next, I created the Nativeprocessstartupinfo object and set the executable properties. I also create a parameter vector and set it to the parameter properties of the Nativeprocessstartupinfo. It is then passed to ARGC, which is the variable of my executable.

Finally, I created an nativeprocess instance to add an event listener for Progressevent.standard_output_data. I started this process and closed the input.

The executable will simply consult the ARGC, invoke printf, and then trigger the progress event and alert in the air application.

Examples of ActionScript fragments:

private Var process:nativeprocess; Private Function Callnativeapp (): void{var file:file = file.applicationdirectory; file = File.resolvepath ("Nativeapps") ; if (Capabilities.os.toLowerCase (). IndexOf ("Win") >-1) {file = File.resolvepath ("Windows/sample.exe");} else if ( Capabilities.os.toLowerCase (). IndexOf ("Mac") >-1) {file = File.resolvepath ("Mac/sample");} else if ( Capabilities.os.toLowerCase (). IndexOf ("Linux") >-1) {file = File.resolvepath ("Linux/sample");} var Nativeprocessstartupinfo:nativeprocessstartupinfo = new Nativeprocessstartupinfo (); nativeprocessstartupinfo.executable = file; var args:vector.<string> = new vector.<string> (); Args.push ("Rich Trretola"); Args.push ("loves"); Args.push ("Flex & AIR"); nativeprocessstartupinfo.arguments = args; Process = new nativeprocess (); Process.addeventlistener (Progressevent.standard_output_data, onstandardoutputdata); Process.Start (Nativeprocessstartupinfo); Process.closeinput (); } Private Function OnstandarDoutputdata (event:progressevent): void{alert.show (Process.standardOutput.readUTFBytes ( process.standardOutput.bytesAvailable)); }

Sample code:

#include <stdio.h> int main (int argc, const char * argv[]) {if (argc > 1) {int i; for (i=1; i<argc; i++) {Prin TF ("/n"); printf (argv[i]); }} printf ("/n"); return 0; }

Here's the result:

It's enough to lift your appetite.

To get all the source code, you will have to wait for the book to be published.
