I have tried fallowing three different methods, all methods works in my other projects, my current project is a windows service, I'm calling the methods through my class.

When I debug it out I'm not getting exception at any of them !

Try
    Try
        Directory.SetCurrentDirectory("C:\")
        Dim p As New Process
        Dim pi As New ProcessStartInfo
        pi.Verb = "print"
        pi.FileName = FilePATH
        pi.UseShellExecute = True
        p.StartInfo = pi
        p.Start()
    Catch ex As Exception
    End Try
    Try
        System.Diagnostics.Process.Start(FilePATH)
    Catch ex As Exception
    End Try
    Try
        Shell(FilePATH, AppWinStyle.NormalFocus)
    Catch ex As Exception
    End Try
Catch ex As Exception
    MsgBox(ex.Message)
    EventLog.WriteEntry("PEGASUS", "ExecuteFile___" & DateTime.Now & ">>>>" & ex.Message, EventLogEntryType.Warning)
End Try

Solution 1

It's difficult to tell what is going on, because you are swallowing all exceptions. Either remove your inner try blocks and just leave the outer one, or populate your inner catch blocks and report errors.

As it is, any error will be swallowed and never seen by the reporting catch block.

I am almost sure this is about the path, please see my answer.
Good point about exception blocking! I put my recommendations on proper techniques.
My 5 for you.

First of all, you need to check batch file path and access this path properly in your application.
You should never assume it is in your working directory, even if you put your file in your executable directory. The working directory totally depends on where your start your executable.

Let's assume you put your file in your executable directory. More exactly, this is the directory of the "main module of entry assembly". This is how to find out its path:

C#

exePath = System.IO.Path.GetDirectoryName(
    System.Reflection.Assembly.GetEntryAssembly().Location);

By the way, Griff is right on exceptions: you should not block exception propagation like you do!
See this:
How do i make a loop that will stop when a scrollbar reaches the bottom[^]
When i run an application an exception is caught how to handle this?[^]
This is also important if you ask a CodeProject Question.
