winforms - Log batch in listbox C#? -

i working on program, can handle minecraft servers. running batch witch logs server, , want batch (called batch in code) log in listbox called lg_log.

if possible, how can that?

i programming in visual studio - windows forms in c#.

edit: code:

process batch = new process();  string pathtorunfile = @"\servers\base\start_server.bat"; string current_directory = directory.getcurrentdirectory(); string server_base = @"\servers\base"; string working_directory = current_directory + server_base;  batch.startinfo.filename = current_directory + pathtorunfile; batch.startinfo.arguments = ""; batch.startinfo.workingdirectory = working_directory;  batch.startinfo.useshellexecute = true; batch.start(); 

the process.startinfo contains properties redirectstandardoutput. setting flag true, able add event handler batch.startinfo.outputdatareceived , listen events. so:

edit: might want enable redirecting erroroutput in order receive error messages.

edit: requested, here working example. make sure test.bat exists.

using system.diagnostics; using system.drawing; using system.windows.forms;  public class program {     public static void main() {         var form = new form {clientsize = new size(400, 300)};         var button = new button {location = new point(0, 0), text = "start", size = new size(400, 22)};         var listbox = new listbox {location = new point(0, 22), size = new size(400, 278)};         form.controls.addrange(new control[] {button, listbox});          button.click += (sender, eventargs) => {             var info = new processstartinfo("test.bat") {useshellexecute = false, redirectstandardoutput = true};             var proc = new process {startinfo = info, enableraisingevents = true};             proc.outputdatareceived += (obj, args) => {                 if (args.data != null) {                     listbox.items.add(args.data);                 }             };             proc.start();             proc.beginoutputreadline();         };          form.showdialog();     } }
