How to run a batch file from vb form 1

[cmn2]

Greetings
I have an app that writes an ftp script file and also writes a batch file to execute the script file. When I double click on the batch file it runs the script file perfectly. Now I want to eliminate the double click and run the batch file automatically from my app. I am using the following line to try to accomplish this but cannot get it to work.

System.Diagnostics.Process.Start("C:\MyBatchFile.bat")

Does anyone have experience to lend on how to execute a batch file from a vb app? Thank you.

Hi,

when I need to launch an external file, I allways use:

  Process.Start("filePath")

hmmm.. it strangely looks like your line of code, but I don't think this (the one I use) Process class comes from the "System.Diagnostics" namespace as I don't have any reference to it in my test project.

A batch file is not a program file and so needs to be started slightly differently. Look at the various options under System.Diagnostics.Process - there is a parameter that you can set to force it to run a file which is of a known type. Alternatively pass your batch file as the parameter to cmd.exe in System.Diagnostics.Process


Hope this helps.

Thanks for sticking with this. I will try it out later today and will post back.

This is what finally worked for me. Setting the WorkingDirectory was the key. Thanks for all of your help, I appreciate it.

Dim p As New Process
p.StartInfo.WorkingDirectory = "C:\BatTest"
p.StartInfo.FileName = "c:\BatTest\MyBatchFile.bat"
p.Start()
p.WaitForExit()
p.Close()
