im having problems running a .bat file from vb.net 2005 this is the code im using

CODE

Dim startInfo As System.Diagnostics.ProcessStartInfo
        Dim pStart As New System.Diagnostics.Process

        startInfo = New System.Diagnostics.ProcessStartInfo("C:\my.bat")

        pStart.StartInfo = startInfo
        pStart.Start(startInfo)
        pStart.WaitForExit()



now if i leave waitforexit in it errors if i comment it out a dos window will flash up and go again but it has not run my bat file...

this is what the error says in Details.. {"No process is associated with this object."}

not sure why this is

thanks for reading

vb

System.Diagnostics.Process.Start("notepad")


Make sure that you do not put the .exe at the end.

this will not work as it opens the .exe... i have an exe and a .bat in the same dir this is what is inside my .bat

mktex car000.tga car000.tex

then when i run the .bat it runs the exe with the above command so it converts my tga car template to a .tex to run in game (aslong as the car000.tga is in the same file!!

You are calling a shared/static member of process.start, the one you are calling returns a new process. Simply remove the startinfo parm from the .start.

vb

        Dim startInfo As System.Diagnostics.ProcessStartInfo
        Dim pStart As New System.Diagnostics.Process

        startInfo = New System.Diagnostics.ProcessStartInfo("C:\my.bat")

        pStart.StartInfo = startInfo
        pStart.Start()
        pStart.WaitForExit()

vb

        Dim pStart As New System.Diagnostics.Process
        pStart.StartInfo.FileName = "C:\my.bat"
        pStart.StartInfo.WorkingDirectory = "C:\" 'Set to where ever the files you want to convert are
        pStart.Start()
        pStart.WaitForExit()


My guess is that you need to change the working directory in the startinfo, the batch is not finding any files in the default working directory which is were the exe is compiled to.
