BeSharp.net: PowerShell script to show the component packages (BPL) files for all installed Delphi (actually: BDS) versions.

Posted by jpluimers on 2014/11/13

A while ago, I wrote a via PowerShell script to show the component packages (BPL) files for all installed Delphi (actually: BDS) versions (now at List-Delphi-Installed-Packages.ps1) for a couple of reasons:

  • I was creating installation instructions for getting new development machines set-up
  • The new machines had to either have a minimum subset of installed Delphi versions  + components, or the maximum superset of all the existing development machines
  • Sifting through the installed Packages in the IDE, or registry by hand was cumbersome

Note that in the mean time (I queued this blog entry somewhere in 2013) the script has moved to BitBucket, I’ve written more scripts (like Dependencies.bat which is documented in Dependencies.md and Run-Dependend-rsvars-From-Path.bat), all modified all scripts to support all BDS versions I had access to, and a write nice conference paper on Build Automation for Delphi that references the scripts.

Since none of the machines were using pre BDS installations, I could limit the script to BDS 1.0 and up.

The very first (1.0) version of BDS (also known as the Gailileo IDE foundation) was in fact not a Delphi version, but C# Builder 1.0. All Delphi versions since then are based on BDS. The script is based on the BDS registry keys I researched and wrote about in Files in your Delphi settings directory; How to relocate the Favourites on your Welcome page.

Since registry access can be very much flow based, the pipeline architecture of PowerShell is a good fit.

So I wrote a PowerShell script (:

Note Thomas Mueller has written a batch file around the same set of registry keys; the thread there also has some insight in the HKLM versus HKCU keys.

I will explain my script step by step, and start with the most important one: Set-StrictMode -Version Latest. Read the rest of this entry »

PowerShell: 3 ways of `not` (except `not` itself: that doesn’t work) via Stack Overflow

Posted by jpluimers on 2014/11/05

Thanks Ryant for posting this answer, which I’ve paraphrased a bit:

not itself is not a boolean operator in PowerShell.

The reason is that PowerShell borrows a lot from *nix history, and this has been in *nix forever.

So there are 3 ways of negating a boolean, all equivalent: Read the rest of this entry »

Indent/Unindent text in PowerShell ISE

Posted by jpluimers on 2014/10/31

When searching for powershell ise indent tab, I came across this very nice post by rpscripter:

If one selects multiple lines, then pressing tab will indent them all.  Pressing shift+tab will un-indent them all.

Yes, I know the PowerShell is limited, so the indents are tabs (not spaces) and you cannot change the tab size: Powershell ISE – change indent/tab size + keep tabs.

Windows consoles: a small list

Posted by jpluimers on 2014/06/19

Many people confuse a shell with a console.

They are distinct: the shell executes commands, and the console hooks up video and keyboard to them.

Some products (like Take Command Console, of which Noah Coad is a huge fan) combine the two.

Some shells you can use for Windows: Read the rest of this entry »

Windows shells: a bit of history

Posted by jpluimers on 2014/06/18

I’ve a long history in DOS/Windows 9x COMMAND.COM and Windows cmd.exe shell programming.

The switch to PowerShell is steep, but for me it is worth it: it has so much more functionality than cmd.exe, and taps right into the .NET ECO system.

If you look for something intermediate, you might want to consider TCC. Formerly TCC was known as 4NT, which has its roots in 4DOS (I totally loved 4DOS back when cmd wasn’t there yet).

Wow, it seems I’ve been living under a stond since early 2011: the first StudioShell checkin.

Easiest way to grant/query “Log on as a service” to a Windows user from the command-line? (my question on Super User)

Posted by jpluimers on 2014/04/28

I want to script an install where a service needs to be run as a user. I want to be able to specify the user.

Creating the user is easy through the [Wayback/Archive] NET USER /ADD command.

Specifying the user for the service can also be done: the [Wayback/Archive] SC CONFIG command [Wayback/Archive] allows this (thanks [Wayback/Archive] wmz and [Wayback/Archive] ofiris).

Now the missing link: granting the user the [Wayback/Archive] “Log on as a service” privilege as a [Wayback/Archive] logon right (SeServiceLogonRight). Is there a command for this? Or a simple script for PowerShell?

(I know only Local Service can do this out of the box, and [Wayback/Archive] no other accounts by default are, but I want to have control over the account and what other privileges that account has).

Edit: solved. Thanks [Wayback/Archive] Mathias R. Jessen.

Here is the solution, including a few comments.

The easiest way to do this from a command line is definitely using NTRights.exe from the Windows Server 2003 Resource Toolkit.

ntrights +r SeServiceLogonRight -u jeroen -m \%COMPUTERNAME%

I changed the command-line a bit:

ntrights +r SeServiceLogonRight -u %USERNAME% -m \%COMPUTERNAME%

Note that

whoami /all

doesn’t show any change (not even after a reboot, it does not matter if you run it with or without UAC token).

secpol.msc

does show the change however, and does not require UAC (follow the tree to “Security Settings -> Local Policies -> User Rights Management -> Log on as a service” to see the users having the permission).

–jeroen

via: [Wayback/Archive] Easiest way to grant “Log on as a service” to a Windows user from the command-line? – Super User.

PS: Later I found out it is way easier to query the right:

accesschk.exe /accepteula -q -a SeServiceLogonRight

It will list the users having that right, for instance:

        IIS APPPOOLClassic .NET AppPool
        NT SERVICEALL SERVICES
        VCS-CIContinuaCI

There are similar rights one might want to query:

SeBatchLogonRight
SeDenyBatchLogonRight
SeInteractiveLogonRight
SeDenyInteractiveLogonRight
SeServiceLogonRight
SeDenyServiceLogonRight
SeNetworkLogonRight
SeDenyNetworkLogonRight

PowerShell conditional and logical operators (via: PowerShell Pro!)

Posted by jpluimers on 2014/04/03

Switching between many different languages, I tend to forget the exact names and symbols of the PowerShell operators.

Most of the ones I use have to do with comparison and logic, o here they are:

Most used comparison operators

Operator Description
-eq Equal to
-lt Less than
-gt Greater than
-ge Greater than or Eqaul to
-le Less than or equal to
-ne Not equal to

Logical operators

Operator Description
-not Not
! Not
-and And
-or Or

I find it funny that you have ! and -not, but not -!. Oh well (:

Talking about logicals: PowerShell can coerce a couple of values to $false, but I’m ambivalent to use that: it does shorten code, but is very PowerShell specific.

Before I forget: an operator that is undervalued, is the -f operator that does formatting.

It uses the standard .NET formatting strings, so that is an easy way to put your .NET knowledge to use. Some further reading on the -f operator:

Escaping in PowerShell: the back-tick ` is the escape character.

Posted by jpluimers on 2014/04/03

Somehow I always forget this:

The PowerShell escape character is the backtick “`” character.

Use it for escaping quotes within quotes, or inserting special characters.

Don’t abuse it (see the great debate: do not use it as a line continuation).

Often you can avoid line continuation characters by using splatting, which is one of the “best kept secrets” in PowerShell.

Getting Microsoft Product Keys back from the registry (via StackOverflow and various other sources)

Posted by jpluimers on 2014/04/02

Every once in a while, someone hoses their computer far enough that it has to be reinstalled, but the original Microsoft product keys are misplaced, and some creepy anti-virus tool disallows the running of standard product key recovery tools like nirsoft’s.

Well, there is enough sourcecode that does recover it, just look for any of these strings:

Some hits:

The below full executables can trigger a virus warning (ordered from less often to most often):
