Check if a program or process is running (Windows)Tag(s): Environment
Based on this HowTo which list the currently running processes, we adapt it to check for a specific program name.
In this example, we check if the text editor TextPad.exe is running.
import java.io.BufferedReader;
import java.io.File;
import java.io.FileWriter;
import java.io.InputStreamReader;
public class VBSUtils {
private VBSUtils() { }
public static boolean isRunning(String process) {
boolean found = false;

file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
String vbs = "Set WshShell = WScript.CreateObject(\"WScript.Shell\")\n"
+ "Set locator = CreateObject(\"WbemScripting.SWbemLocator\")\n"
+ "Set service = locator.ConnectServer()\n"
+ "Set processes = service.ExecQuery _\n"
+ " (\"select * from Win32_Process where name='" + process +"'\")\n"
+ "For Each process in processes\n"
+ "wscript.echo process.Name \n"
+ "Next\n"
+ "Set WSHShell = Nothing\n";
fw.write(vbs);

new BufferedReader
(new InputStreamReader(p.getInputStream()));

if (line != null) {
if (line.equals(process)) {

}
}
input.close();
}
catch(Exception e){

}
return found;
