Oh yes, and one other issue that am not too sure where/why it arose was that the batch file I had created as a text file, and then renamed within VS.Net 2008 kept on giving me an execution error along the lines of:
--n echo is not recognized as an operable....

error message, but I then recreated it using notepad, retyped commands, and pasted file into VS.Net solution explorer and problem went away, so I assume it was something like either just a \n or \r character at the beginning of the first line or something that the command line application (cmd.exe) was picking up, and complaining about, and the only other time have really seen something similar to this was when I created an HTML file in VS.Net, but then renamed it to .php and tried uploading it to a linux box, since if you plan to use <?php session_start... it really needs to be the very first thing in a .php file, but anyway...

Stay well

Ok, FWIW, seems simplest trick is to use the System.Diagnostics.Process to in fact execute a batch file:


System.Diagnostics.Process proc = new System.Diagnostics.Process();

proc.EnableRaisingEvents = false;

proc.StartInfo.FileName = stAppPath + "playlist.bat";

proc.StartInfo.Arguments = fils[I].Substring(2, (fils[I].Length - 2));

proc.Start();

proc.WaitForExit();



fils[] string array is something am populating using System.IO.Directory.GetFiles(), and stAppPath is assigned a value from

System.IO.Directory.GetCurrentDirectory() fwiw;


Only real issue now is that if the argument strings have spaces in them, they get seen as multiple arguments, so unless can confirm if can do a form of search/replace within batch file, I'll do something like specify up to around 5-10 of them in case:
echo %1 %2 %3 %4 %5 %6 %7 %8 %9 %10 > zFile.txt

And that should work around the spacing issue, but let's see...might just go over to actual windows app, and stream playlist file contents myself from within code, but anyway...

Other thing remembered is that within the actual batch file/command line instance while > will redirect to a newly created/replaced file, >> will in fact append to an existing file.

You can also easily enough use System.Console.WriteLine to output status messages, but jaws, for example doesn't read them to me automatically.
