I have an exe vb.net application and a bat file located in the same drive in different folders. Шhen I try to execute the bat file, it is executing properly. Problem occurs when I try to execute the file using the code.

What I have tried:

Private Sub runBatchFile()
Try
Dim Psi As New ProcessStartInfo("D:\TaskSchedular_W207\MysqlBackup_2.bat")
Psi.RedirectStandardError = True
Psi.RedirectStandardOutput = True
Psi.CreateNoWindow = False
Psi.WindowStyle = ProcessWindowStyle.Hidden
Psi.UseShellExecute = False

Dim process As Process = process.Start(Psi)
Catch
MessageBox.Show("Could not start process")
End Try

End Sub

Probably it's a permissions problem: the task scheduler runs under a privileged account and your user doesn't, so you user who runs your app may not be able to access the file at all.
To find out, get the exception code in your catch block:

VB

Catch ex As Exception
   MessageBox.Show("Could not start process: " & ex.Message)
End Try

And use the debugger to look at both the message and other info it contains.
