I have an .exe file that needs to be run after I create a file. The file is successfully created and I am using the following code to run the .exe file after that:
ProcessStartInfo processInfo = new ProcessStartInfo();
processInfo.FileName = pathToMyExe;
processInfo.ErrorDialog = true;
processInfo.UseShellExecute = false;
processInfo.RedirectStandardOutput = true;
processInfo.RedirectStandardError = true;
Process proc = Process.Start(processInfo);
I also tried with a simple Process.Start(pathToMyExe); but the .exe file is not run. When I try pathToMyExe manually on my Windows Explorer the program is correctly run. But not via the program. What I see is the cursor turning to waiting for a few seconds and then back to normal. So there are no Exceptions thrown either. What is blocking the file?
You are not setting the working directory path, and unlike when starting the application through Explorer, it isn't set automatically to the location of the executable.
Just do something like this:
processInfo.WorkingDirectory = Path.GetDirectoryName(pathToMyExe);
(assuming the input files, DLLs etc. are in that directory)
private void Print(string pdfFileName)
{
string processFilename = Microsoft.Win32.Registry.LocalMachine
.OpenSubKey("Software")
.OpenSubKey("Microsoft")
.OpenSubKey("Windows")
.OpenSubKey("CurrentVersion")
.OpenSubKey("App Paths")
.OpenSubKey("AcroRd32.exe")
.GetValue(string.Empty).ToString();
ProcessStartInfo info = new ProcessStartInfo();
info.Verb = "print";
info.FileName = processFilename;
info.Arguments = string.Format("/p /h {0}", pdfFileName);
info.CreateNoWindow = true;
info.WindowStyle = ProcessWindowStyle.Hidden;
////(It won't be hidden anyway... thanks Adobe!)
info.UseShellExecute = false;
Process p = Process.Start(info);
p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
int counter = 0;
while (!p.HasExited)
{
System.Threading.Thread.Sleep(1000);
counter += 1;
if (counter == 5)
{
break;
}
}
if (!p.HasExited)
{
p.CloseMainWindow();
p.Kill();
}
}
Due to different working directory, you have to set your working directory properly to the path that you want your process to start.
A sample demonstration of this can be:
Process process = new Process()
{
StartInfo = new ProcessStartInfo(path, "{Arguments If Needed}")
{
WindowStyle = ProcessWindowStyle.Normal,
WorkingDirectory = Path.GetDirectoryName(path)
}
};
process.Start();
