i tried to get exe file callback result when i doing shell execute like this:
var oShell = new ActiveXObject("WScript.Shell");
var args = folderName + "\\dir\\scan.exe scan " + params.join(" ");
var ret = oShell.Run(args ,0 ,true);
but ret gaves me 0 for fail and 1 for success. when i run the file in the cmd like this:
scan.exe arg1 arg2 arg3
this is return the correct result that i wanted : "test/test" and not 1...
what can i do?
tnx a lot
I know I might be a bit late to answer this question but I hope it can still help someone.
The way I achieved it was with the oShell.Exec() function and not with the oShell.Run().
oShell.Exec() returns an object with a property called StdOut which acts like a text file, so you can perform ReadLine(), ReadAll(), etc.
The problem is that it does not wait for the command to end, so when you run your code, it is very likely that your StdOut object will be undefined. You have to add that waiting option on the command itself.
var wshShell = new ActiveXObject("WScript.Shell");
try {
// Excecute the 'cd' command.
wshShell.CurrentDirectory = "C:\\Users";
var execOut = wshShell.Exec('cmd /C start /wait /b cd');
}
catch (e) {
console.log(e);
}
// Get command execution output.
var cmdStdOut = execOut.StdOut;
var line = cmdStdOut.ReadLine();
console.log(line);
The code above will execute a cd command on the directory C:\Users and store the output on the line variable.
I hope this answers the question.
Using a shell to receive output from BATCH file:
script.js
var pathToFile = "your_path_here"
var shell= new ActiveXObject("WScript.shell");
var output = shell.Exec(pathToFile + 'example.bat');
var response = output.StdOut.ReadLine();
console.log(response)
example.bat
@ECHO OFF
echo Hello From Batch World
exit 0
