Problems running an app from within a script

I have a simple and basic question about running external apps from a
script. If, within a script, I have this:


-----------------------------------------

$Path = "C:\Temp"

TestApp.exe "$Path\File.txt"

-----------------------------------------

...then it works fine.



However, if I have this:



-----------------------------------------

$TextEditor = "TestApp.exe"
$Path = "C:\Temp"

$TextEditor + " " + "`"$Path\File.txt`""

-----------------------------------------

...what happens is that the line is displayed like a text string, but
never actually executed.



What am I doing wrong?

You have to use that string as a -command parameter for cmdlet invoke-
expression (Runs a Windows PowerShell expression that is provided in
the form of a string.) like:

invoke-expression -command ($TextEditor + " " + "`"$Path\File.txt`"")
or

invoke-expression ($TextEditor + " " + "`"$Path\File.txt`"") or even
shorter (if you use it in a console)

iex ($TextEditor + " " + "`"$Path\File.txt`"")

Thats because its just a string. Consider this:

PS > "notepad.exe"
notepad.exe

notepad is not executed, it is treated as a string. To invoke it:

$n = "notepad.exe"
$file = "$profile"

invoke-expression "$n $file"

This will load your profile into notepad. Likewise, you can use the Call
operator (&):

& $n $file
