Even when not using Visual Live Binding, Delphi generates empty .VLB files in both Delphi XE3 (virtually always) and Delphi XE4 (most of the time).
Visual Live Binding is one way of binding data to UI in FireMonkey and can also be used in VCL, but does not have to (Alister Christie made a nice video ▶ Delphi Training Tutorial #77 – Visual Live Bindings – YouTube about it).
Empty VLB files, and a batch file to delete them
The “empty” VLB files are almost empty, as they are exactly 3 bytes long and contain the byte sequence EF BB BF which is the Unicode BOM (byte order mark) for the UTF-8 encoding. Read the rest of this entry »

One more of the “Missed Schedule” series, this time it was originally scheduled for October 1st, (2013 that is).
Delphi XE2 and up introduced the FrameworkType and FormType elements in the .dproj files to distinguish between VCL and different flavours of FireMonkey.
Actually, Delphi XE1 already had the value None for FrameworkType, so some cross-platform changes trickled into the Delphi builds early.
Though the IDE writes these values to the .dproj files, you [Wayback/Archive] cannot change their values from within the Delphi IDE, not even through the Open Tools API.
There is no documentation about the values in the .dproj files. the only places I could find were these about FrameworkType in combination with [Wayback/Archive] Actions:
that basically tell this:
FrameworkType
Defines whether an action is created for the VCL or FireMonkey (FMX) framework. The default of this parameter is VCL (for compatibility with legacy applications).
This parameter is used to avoid situations when VCL actions are used in FireMonkey applications and inversely; this can lead to a serious increase in an application’s size and to execution errors, for example, calling of Windows API under MacOS.
But it is incomplete, and there is no documentation about FormType. Read the rest of this entry »

Another instalment in the WordPress Missed Schedule series (:
Each version, Delphi gets more features, and grows bigger.
Especially in testing environments (where you want to have a cut-down base machine you can clone from), it is wise to cut down on the installation size.
A few directories you might want to consider compressing for your Delphi installation:
C:\Users\All Users\{*}
The directories with GUID names contain the installer cache. You can ditch the whole installer cache if you keep ISO images of all installations. I prefer just to compress these directories.
Compressing usually saves 50% of the storage there, which can count for 5+ gigabyte of savings for the newest Delphi version.C:\Users\Public\Documents\RAD Studio
Contains (among others) the help files and SVN examples, and (for the most recent version) the Platforms SDKs.
Saving is usually a couple of 100 megabytes for less recent Delphi versions until about 1 gigabyte for the most recent.C:\Program Files (x86)\Embarcadero\RAD Studio\#.0\lib
This contains all the precompiled files. Since they are readonly in nature, it pays of compressing them, usually saving 50% or more.
Saves 5+ gigabytes for the most recent Delphi version.

Another one in the “WordPress Missed schedule” series.
Below are the Android remote screen monitoring/viewer/mirror tools I know about:
- For a long time, I have used Droid@Screen: an Open Source, Java based mature cross platform tool that uses ADB (it can even restart it for you in case it hangs) with lots of features (zooming, no temporary files, device recognition, disabling emulator devices, etc). There are some Screen Shots | Droid@Screen.
- A while ago, I saw android-screen-monitor – Android Screen Monitor – Google Project Hosting. It is a mixed Java/C++ solution that only works on Windows.
- Recently, Jim McKeeth open sources his Android Screen View: Android Screen View | The Podcast at Delphi.org. It is written as a quick hack in Delphi XE5, so right now it has less features and works in a more crude way than the two Java based tools, but it shows the potential of doing similar things with Delphi.
I primarily use Droid@Screen as so far it works best for me.
But I keep a close eye on the other two just to make sure I don’t miss improvements.

If you an error like below when compiling Delphi XE5 .dproj files using msbuild … then note the documentation for Debug information (Delphi) – RAD Studio. has not been updated yet as it still lists the values {$D+} or {$D-} {$DEBUGINFO ON} or {$DEBUGINFO OFF}.
(_PasCoreCompile target) -> C:\Program Files (x86)\Embarcadero\RAD Studio\12.0\Bin\CodeGear.Delphi.Targets(187,5): error F1026: File not found: 'False.dpr'
With Delphi XE5, you can specify 3 additional values: {$D1}, {$D2} and {$D0}, or {$DEBUGINFO 1}, {$DEBUGINFO 2} or {$DEBUGINFO 0}
In the msbuild .dproj files , the values are stored as DCC_DebugInformation elements. Read the rest of this entry »

This summer was rough with some intestine issues, so I was really happy the recovery worked out and I could make it to a couple of conferences this fall.
ITDevCon 201 3was one of them, and I had great fun!
The BitTime people organizing the conference took many nice pictures of which one of me when I was explaining MVVM.
Note that the conferences downloads are online at https://bitbucket.org/jeroenp/conferences/src/tip/2013, so even if you didn’t make it you can still watch he slides and play with the examples.
Thursday there is one more conference to go: Be Delphi, and I will upload the materials from there as well.

Researched this a long while ago, but just presented this at my Delphi cross-platform session on ITDevCon 2013 (of which some sessions have been broadcasted on YouTube):
With Android 4.2 and up, they did hide the debug mode a bit.
Perform these steps one to enable debug mode:
- Go to “Settings”.
- Scroll down to “About phone” or “About tablet”.
- Tap on “About phone” or “About table” to go to the “About” screen.
- In the “About” screen, scroll down, to “Build number”
- Tap on “Build number” seven (7!) times. It will give you some messages until finally it shows “You are now a developer”.
- (On some devices): confirm with the PIN code for your phone.
The above steps unlocked the “USB debugging” mode.
To enable or disable “USB debugging” mode:
- Go to “Settings”
- Choose “Developer Options”
- Choose “Debugging”
- Choose “USB Debugging”

Early bird ends October 4th: get an Android tablet for free and save EUR 100!
EKON17 (from November 4-6 in Cologne, Germany) will be a fun event this year: lots of nice sessions and workshops, a lovely city (not just the Dom Cathedral), and a great group of speakers.
Since there are so many speakers that are able to speak English, it is interesting for non-German attendees as too, especially the post-conference workshop from Nick Hodges.
I’ll be speaking too (more on that below) and will be there all 3 days (plus the evening before and morning after to aid people with their Delphi related questions).
Among the speakers, these will do their sessions in English:

You will see a few Delphi XE5 pre-release related updates here soon. That is part of the Delphi XE5 beta blogging permission I have been given so I can show new Delphi XE5 features. Those updates are from a pre-release version of Delphi XE5 and will be replaced with a final update when Delphi XE5 is being released.
For more information about Delphi XE5 and the Android support, please visit http://embt.co/RADAndroid.
Though not as fast as I hoped (I’ve slept most of the past days), I’m already preparing my Mercurial repositories at https://bitbucket.org/jeroenp, and preparing for the PasCon / RAD Studio In Action in Leiden, The Netherlands next saturday so stay tuned.
About this event: there are a few seats left, and a last-minute discount recently launched. Book your tickets through the on-line links for EUR 35 excluding VAT (normallu EUR 49 excluding VAT): Read the rest of this entry »

While working on my Delphi: First try on an XSD for .groupproj files, I bumped into an error `Namespace ” is not available to be referenced in this schema`.
I added a targetNamespace attribute to the GroupProj.xsd so the .grouproj files would use the right namespace.
That resulted into two funny errors:
- Namespace ” is not available to be referenced in this schema.
Visual Studio (which I normally use for editing XSD) would only throw this error on these elements:
<xsd:element ...>
So it would not throw them on nodes using the empty namespace.
That was really confusing!
- When validating .grouproj files using this GroupProj.xsd, I would get this error for all .groupproj files:
System.Xml.Schema.XmlSchemaValidationException: Type ‘<type>’ is not declared. (in this case for ‘<type>’ ‘ProjectType’).
That was odd too: the ‘ProjectType’ was indeed declared, and should be valid.
I could hardly find any information about the latter error, but the former gave a few useful hits.
Thanks User weston – Stack Overflow. for answering this: it made me smack to my head (like usual, a case of EBCAK). Read the rest of this entry »
