Getting Desktop Path

[robopp 0]

Is there a way to get the desktop path programatically? The cmd desktop path shortcut - %userprofile%/desktop - doesn't work.

Not built in.  I would probably use a trick, probably with a batch file.  The batch file would just have something like:

echo %userprofile%/desktop > c:\data\desktopPath.txt

You'd run it from DAQFactory using shellExecute():

system.shellExecute("cmd.exe","c:\data\myBatchFile.bat")

Then you can simply use the file. functions to read the desktopPath.txt file and get the results.

This is off the cuff, but should work, possibly with minor tweaks.  Test each part.

Makes sense. Thank you!

Hi, I'm also trying to run a batch file, and "system.shellExecute("cmd.exe","c:\data\myBatchFile.bat")" doesn't do anything. 

function LoadAutosamplerFile(string que_file)
   //try
      private string script_dir = "C:\Peak489Win10\LoadCtrlFile.bat"
      private handle = file.Open(script_dir, 0, 1, 0, 1)
      File.Write(handle, "cd C:\Peak489Win10")
      File.Write(handle, "Peak489Win10 -a" + que_file)
      File.Close(handle)
      system.ShellExecute("cmd.exe","C:\Peak489Win10\LoadCtrlFile.bat")
      ?"Batch file (allegedly) executed"
      return 1

Figured it out, the command to launch a batch file with shellExecute is 

system.ShellExecute("cmd.exe", "open", "/C C:\data\myBatchFile.bat") 

At least thats the way I got it to work, hope this helps if anyone is looking for how to do that.

Yes, that would be the way.  You can't just pass a batch file to CMD.exe, but instead have to use a flag to tell it to run the particular file.  You can use /C or /K depending on whether you want the window to stay open.
