Is it possible to pass parameters to a PS script when invoking it from
Command Prompt or another (say VB.net) program?



Thanks,
Dan

Yes. -ParamName

In the script you define the params like so

=== Script ===
Param($Param1,$Param2)
write-host $param1
write-host $param1
===========

From the DOS prompt or batch
powershell.exe Path\ScripName -Param1 Hello -Param2 There

Assume you have a script test.ps1

param([string]$msg = "test")
write-host $msg

you can invoke the script and pass the parameters like this

powershell.exe -command "& c:\scripts\monad\test\test.ps1 'Hello'"

Thank you again Brandon and RichS.
Both answers were helpful.

However with set-PSdebug -strict I get the message:

The term 'param' is not recognized as a cmdlet, function, operable program,
or script file. Verify the term and try again.
At E:\iris\scripts\powershell\Parametertest.ps1:7 char:6
+ Param <<<< ($a, $b)

Does this work as intended?

And how can I use get-help to get more details about param?

Thank you very much,
Dan

Is your script like this (Perl habits, perhaps?)?

Set-PSdebug -strict
param (...)

Then it is not correct. 'param' (if exists) must be the first statement. So,
use this:

param (...)
Set-PSdebug -strict

I need now to invoke a PS script with parameters from a VB 2005 program.
I tried both versioned mentioned above:

Shell("powershell.exe e:\test.ps1 -param1 pathA -param2 computerB ")

Shell(""powershell.exe -command "& e:\test.ps1 -param1 pathA -param2
computerB """).

Both are accepted syntactically, both execute the script but without passing
the parameters.

What am I doing wrong?

Thank you very much,
Dan

This one works for me

Shell("powershell.exe c:\scripts\test.ps1 -param1 pathA -param2 computerB")

Consider the following. create a VBS file and a PS1 test file then execute
the VBS file.
On my machine, both run successfully.

###### vbs file ####
Set oShell = CreateObject("WScript.Shell")

'Option 1
oshell.run "powershell.exe c:\test.ps1 -param1 pathA -param2 computerB"

'Option 2
oshell.run "powershell.exe -command & {c:\test.ps1 -param1 pathA -param2
computerB}"


###### c:\test.ps1 ####
param($param1,$param2)

$param1
$param2


###### PowerShell output ####
pathA
computerB

You don't need to create a new process and run powershell.exe. Just do
this:

using (RunspaceInvoke ri = new RunspaceInvoke())
{
Collection<PSObject> results =
ri.Invoke("e:\test.ps1 -param1 pathA -param2 computerB");
}

Sorry about the C#, it shouldn't be difficult to convert to VB.
