Passing Autoit exe return value into Java

[EamonB]

I am doing some simple tests in eclipse where I pass parameters from Java code into my AutoIt exe successfully.

But now I want to see if there is a way in Java to capture whether or not the AutoIt exe ran correctly (possibly by having the executable return a boolean that can be passed back to the Java code)

Here is my original sample code

String[] cmd = new String[3];

cmd[0] = AutoItScripts.compareDocsWord;
cmd[1] = "C:\\Users\\Eamon\\Desktop\\file1.doc"; 
cmd[2] = "C:\\Users\\Eamon\\Desktop\\file2.doc";
        
Runtime.getRuntime().exec(cmd);

Although I understand the code below obviously doesn't work, I was wondering if there was any sort of way to pass the result of the AutoIt exe back into Java in a way similar to this example

int x = 5;

String[] cmd = new String[3];
cmd[0] = AutoItScripts.compareDocsWord;
cmd[1] = "C:\\Users\\Eamon\\Desktop\\file1.doc"; 
cmd[2] = "C:\\Users\\Eamon\\Desktop\\file2.doc";
        
Boolean result = Runtime.getRuntime().exec(cmd);
if (result==false)
    x+=7;

It's okay to bump after 24 hours, but please don't create multiple threads on the same issue.

My bad. I didn't know how to delete my previous post so I created a new one.
Also, for anyone else's reference, I figured out how to pass values from the executable back into Java.
AutoIt has a thing called Exit return values. Scripts normally return an exit value of 0 if the script executed properly but you can set the exit value to any number above 0 that you want depending on what condition you want to return to Java.

For example, this is my autoit script same code:

$var = 2
if $var > 4 Then
    Exit(1)
Else
    Exit(2)
EndIf

Since $var is less than 4, the script will have the exit value of 2

Here is my corresponding Java code that calls the Autoit exe:

String[] cmd = new String[1];
cmd[0] = AutoItScripts.test;
        
Process result = Runtime.getRuntime().exec(cmd);
result.waitFor();   
    
if (result.exitValue()==1)
    System.out.println("YAY!");
else
    System.out.println("boo");

You can expect the console to print out "boo" instead of "YAY!" because the exit value is not 1 (it's 2 because the value of $var was less than 4).

NOTE: keep in mind that you have to add the result.waitFor() function (waits for the exe to finish running) in your java code before you verify the exit value result because otherwise the java code is going to check the exit value before the executable even finishes running.

Hopefully that helps anyone else that had a similar problem to me!!
