PShell and Get-Member

Joe Caverly · 2026-04-05

Code does not work in v36, but worked in v35.

test.btm

Code:

pshell /s "$jlc = new-object -com jlcUtils.clsMath"
pshell /s "$jlc | Get-Member"

Code:

E:\Utils>ver

TCC  35.00.21 x64   Windows 10 [Version 10.0.19045.7058]

E:\Utils>r:\test.btm
pshell  /s "$jlc = new-object -com jlcUtils.clsMath"
pshell  /s "$jlc | Get-Member"


   TypeName: System.__ComObject#{6952cf31-c8e9-40a2-8e84-e3b7d2122072}

Name   MemberType Definition
----   ---------- ----------
ppp    Method     Variant ppp (Variant)
vb6Val Method     double vb6Val (string)
World  Method     Variant World (string)

Code:

R:\>ver

TCC  36.00.17 x64   Windows 10 [Version 10.0.19045.7058]

R:\>test.btm
pshell  /s "$jlc = new-object -com jlcUtils.clsMath"

pshell  /s "$jlc | Get-Member"
PSHELL: You must specify an object for the Get-Member cmdlet.

I cannot reproduce that since I do not have "jlcUtils.clsMath" (at least).

This demonstrates that there is no persistent PowerShell engine in v36.

Code:

R:\>pshell /s "$fso = New-Object -ComObject Scripting.FileSystemObject"


R:\>pshell /s "$fso | Get-Member"
PSHELL: You must specify an object for the Get-Member cmdlet.

R:\>ver

This demonstrates that there is a persistent PowerShell engine in v35.

In v35 and v36,
this works as it should,
that is,
since the commands are being executed via test.ps1,
no persistent PowerShell is required.

Note well that in v36,
the Get-Member output format of PowerShell 5.1 is not replicated.

Code:

R:\>type test.ps1
$fso = New-Object -ComObject Scripting.FileSystemObject
$fso | Get-Member

R:\>pshell test.ps1

void CopyFile (string, string, bool)

Using PowerShell from TCC without a 3rd party .dll

This works for both PowerShell 5.1, and PowerShell 7.x

Further to my post Use CURL to send/receive commands from a PowerShell 5.1 process

Here is a working example of sending/receiving commands/output from PowerShell 5.1 using TCC v36.

Code:

Thanks Rex.

Now, that's a persistent PowerShell.

I will test when Build 18 is available for download.

Code:

R:\>aiu
Getting File info for https://jpsoft.com/downloads/v36/TCMD.EXE

Release Date   : 2026-04-04
Installed Vers : 36.00.17

Joe Caverly · 2026-04-06

Still the same as build 17

Code:

E:\Utils>ver

TCC  36.00.18 x64   Windows 10 [Version 10.0.19045.7058]

E:\Utils>which pshell
pshell is an internal command

E:\Utils>pshell /s "$fso = New-Object -ComObject Scripting.FileSystemObject"

E:\Utils>pshell /s "$fso | Get-Member"
PSHELL: You must specify an object for the Get-Member cmdlet.

Maybe an issue with Debug Solution Configuration versus Release Solution Configuration in VS?

I tried this in the debug build & it worked. I tried it in the release build 18 and it failed. I rebuilt everything from scratch and tried it again in the release build and it worked. I think the MSVC compiler screwed up something during the batch builds and didn't get the latest code for all the modules.

Try it again when I post build 19.
