Last week, David M Williams posted a nice question on how can I embed an mp4 video into a Firemonkey app.
The resolution – using the Deployment Manager and TPath – was remarkably simple based on my suggestion:
That depends on your platform. Windows can embed and extract resources in your EXE. On other platforms that is either hard or impossible. I’d just deploy the mp4 with your app. `TPath` has some really nice methods to get you directories (Home, Documents, etc) in a platform neutral way, and to combine directories and filenames to form a full path name.
he went along and this was his solution:
Under Project/Deployment I add the MP4 file, then set the MediaPlayer filename property using TPath.

A while ago, I had to disable a couple of warnings from legacy code so I could first perform the Unicode conversion, then make time to eliminate the actual warning cause.
This post was much helpful here:
Marc’s Blog: Delphi XE2’s hidden hints and warnings options.
He lists all the W#### and X#### warnings he could find in Delphi XE2 (XE3, XE4 and XE5 more or less have the same), including the mapping to the equivalent directive IDs used inside these blocks:
{$WARN SYMBOL_DEPRECATED ON}
{$WARN SYMBOL_DEPRECATED OFF}
{$WARN SYMBOL_DEPRECATED DEFAULT}
{$WARN SYMBOL_DEPRECATED ERROR}
I also learned that the DEFAULT value restores an option to what you specified in the project settings.

I’m researching the Spring4D build engine to compile and install the packages and sources for the first Appmethod release.
These are the registry settings that I’ve found:
HKEY_CURRENT_USER\Software\Embarcadero\BDS\13.0
I wonder if the 13 has anything to do with http://docwiki.appmethod.com/appmethod/1.13.
Anyhow: it looks like the next Delphi (XE6) might not use the number 13. Again. Although Allen Bauer was in episode 13 (:

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:
| 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 |
| 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:

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.

If I ever get “R cannot be resolved to a variable” in an Android project again, then I should read these posts:
One of the quotes was the culprit:
*Note: Eclipse sometimes likes to add an “import android.R” statement at the top of your files that use resources, especially when you ask Eclipse to sort or otherwise manage imports. This will cause your make to break. Look out for these erroneous import statements and delete them.*

Wow, I totally missed the introduction of SETX.
From TechNet:
SETX:
Creates or modifies environment variables in the user or system environment, without requiring programming or scripting. The Setx command also retrieves the values of registry keys and writes them to text files.
Even better, is that it allows you take values from these sources so it is easy to get those into environment variables:
- Command-line parameter
- Registry key
- Text file (with some filtering/search options)
From a bit of searching around, I think it got introduced in a Windows Resource Kit, and got included by default starting Windows Vista.
Excellent addition to my toolset (:

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):
