I am trying to run a .bat file (actually a series of them) from a .NET application, and hide (or at least have minimised) the command window - but it will insist on flashing up. Tried with and without the commented out lines below.

Any ideas?

What I have tried:

psInfo = New ProcessStartInfo(Path_to_bat_file)
psInfo.WorkingDirectory = Application.StartupPath & "\bats"
psInfo.WindowStyle = ProcessWindowStyle.Minimized
' psInfo.UseShellExecute = False
' psInfo.RedirectStandardInput = False
myProcess = Process.Start(psInfo)
or, if you prefer:
psInfo = new ProcessStartInfo(Path_to_bat_file);
psInfo.WorkingDirectory = Application.StartupPath + "\\bats";
psInfo.WindowStyle = ProcessWindowStyle.Minimized;
// psInfo.UseShellExecute = false;
// psInfo.RedirectStandardInput = false;
myProcess = Process.Start(psInfo);

The RedirectStandardInput property defaults to false, hence commented or not the same applies.
Try as follows;
// Create 2 stream readers to capture standard output & error if required
StreamReader srOut;
StreamReader srErr;
// create a new process
using(System.Diagnostics.Process proc = new System.Diagnostics.Process())
    proc.StartInfo.UseShellExecute = false;
    proc.StartInfo.RedirectStandardOutput = true;
    proc.StartInfo.RedirectStandardError = true;
    // Set command to run in a hidden window
    proc.StartInfo.CreateNoWindow = true;
    proc.StartInfo.FileName = "Path and Name of BAT file";
    // Set output streams if needed
    srOut = proc.StandardOutput;
    srErr = proc.StandardError;
// read output & error stream if required
string strRead = srOut.ReadToEnd();
string strError = srErr.ReadToEnd();

NOTE: If your Bat file can hang then you will need to terminate it programmatically - it will not be visible on the Desktop
