System.Diagnostics.Process.Start _ from %homepath%

Hello all,

I am trying to execute .bat files from a location that can be modified by all users so have chosen the %homepath% dir, but have thus far been unable to find a way to launch the .bat from this location any help???

Looking for something to the effect of this:

System.Diagnostics.Process.Start _
("%homepath%\batlaunch\meditech.bat")

Version 2008


Any help greatly appreciated!!

You should look up the "SHGetFolderPath" function.

Also, what programming language are you using, VB.Net, C#...?

In VB6 maybe but in .NET its easier to just use Environment.ExpandEnvironmentVariables like so:

vb.net Code:

Environment.ExpandEnvironmentVariables("%HOMEPATH%")

Using Visual Basic 2008 Express Edition

Been googling the ExpandEnvironmentVariables command, but not had much success. How can input the executable path into a button to launch an application in the User directory using this command? How do I orchestrate this, got this so far :)

Environment.ExpandEnvironmentVariables("%HOMEPATH%")

System.Diagnostics.Process.Start _
("%homepath%\batlaunch\meditech.bat")

Also, what area of the form would I place that ExpandEnvironment command?

Thanks!

you have to integrate the ExpandEnvironmentVariables into your file path like so:

Code:

---

System.Diagnostics.Process.Start(Environment.ExpandEnvironmentVariables("%HOMEPATH%") & "\batlaunch\meditech.bat")

---

but you should really also use IO.Path.Combine to combine two paths, as I dont know if your HOMEPATH variable will already have the "\" at the end of it.

Works like a charm!! Thanks so much!

You would more likely do it like this:

Code:

---

System.Diagnostics.Process.Start(Environment.ExpandEnvironmentVariables("%HOMEPATH%\batlaunch\meditech.bat"))
