RAD Studio deployment issues due to anti-virus

Deployment Issues Just a quick heads up for everybody else that have deployment issues similar to the ones below. The underlying reason might be due to anti-virus that is interfering with the deployment process. The connection to the PAServer is successfull, but after copying a few files (visible in the deployment window), RAD Studio gives a connection error and stops deploying. Sometimes, the deployment is succesfull, but shows a "Unable to start GDB kernel" error. Running without debugging has a higher rate of success, but nevertheless, the process of deployment and starting the application is severely disturbed. In either case, running with or without debugging, I have been able to deploy and run 2 out of 30 tries. Below is a snippet of errors thrown while deploying, even though the connection is successfull 100% of the time. macOS [PAClient Error] Error: E0003 Connection to 'MacLarge' on port 64211 failed [PAClient Error] Error: E0003 Please make sure that 'Platform Assistant Server' is running on the host machine and is configured to use port 64211 iOS [DCC Error] E2597 dsymlink: Error: failed to set locale to ??2I? [DCC Fatal Error] F2588 Linker error code: 1 ($00000001) Solution The solution for this issue is simple. Uninstall or disable the anti-virus, or install an anti-virus that does not interfere with this process. On our machine, there was a McAfee license pre-installed on a HP machine that was the culprit of the deployment issues. Leave a comment if you have/had the same issues and which solution you applied to fix the issue.

Delphi Ensuring Left/alLeft or Top/alTop controls are positioned in the right order…

The post [WayBack] Why is my buttons not created in logical order? If I run this, my buttons area created ACB rather than ABC as I expected… – Johan Swart – Google+ reminded me the trouble of Delphi VCL and FMX have with alignment. Basically you have to position your control away from your intended alignment position in order for it to work. So this fails: procedure TForm1.FormCreate(Sender: TObject); var myToolBar: TToolBar; myCornerButton: TCornerButton; i: Integer; begin myToolBar := TToolbar.Create(Self); myToolBar.Parent := Self; for i := 0 to 2 do begin myCornerButton := TCornerButton.Create(tbarGrid); myCornerButton.Parent := myToolBar; myCornerButton.Align := TAlignLayout.Left; myCornerButton.Text := Chr(65 + I); end; end; Basically you have to set myCornerButton.Left to 1 before setting the Align property. Similar for the Top property and TAlignLayout.Top value. The same holds for VCL Align values alLeft with setting the Left property and alTop with setting the Top property before setting Align. See these for the actual properties and types: FMX: FMX.Types.TAlignLayout FMX.Controls.TControl.Align FMX.Controls.TControl.Left FMX.Controls.TControl.Top VCL: Vcl.Controls.TAlign Vcl.Controls.TControl.Align Vcl.Controls.TControl.Left Vcl.Controls.TControl.Top See also this question: [WayBack] Delphi: How to programmatically adjust visual ordering of components with align = alTop –jeroen

Delphi built-in data types and their memory sizes

Installation and GetIt Workarounds for Delphi 10.3.2 (Updated)

Some of the Embarcadero servers (in one of the web farms) are experiencing some severe and prolonged outage. This is affecting (among other things) Delphi 10.3.2 installation. As a temporary workaround, the company has: provided the direct link to the ISO installer download, https://community.idera.com/developer-tools/b/blog/posts/10-3-2-installation-workarounds set up a new GetIt server to allow customers on 10.3.2 (and partially also on older 10.3.x versions) to install the most relevant add-ons and packages, like FMX Linux and Boost: https://community.idera.com/developer-tools/b/blog/posts/temporary-10-3-2-getit-server-for-installing-10-3-2-add-on-packages We should soon have the regular GetIt-based offline installer for 10.3.2 working again with the temporary server.  August 1st Update We now have the ability to install 10.3.2 via GetIt using this temporary system, there is no need to change the GetIt URL manually, as it is embedded in an updated installer. And CodeCentral MyRegistered products is online again with the updated downloads.  Read more on the latest status at https://community.idera.com/developer-tools/b/blog/posts/new-10-3-2-getit-installer.

delphi – Why variables are declared as TStrings and created as TStringList? – Stack Overflow

Blast from the past: [WayBack] delphi – Why variables are declared as TStrings and created as TStringList? – Stack Overflow Q Why variables are declared as TStrings and created as TStringList? A Because that way you could put another TStrings descendant in the SL variable (I’d probably call that Strings, not SL). In your case, that is moot, since the logic around SL contains the creation of a TStringList and no external assignment or parameter parsing. But if you ever split the logic away from the assignment, then you could benefit from using any TStrings descendant. For instance, a TMemoy.Lines, TListBox.Items, TComboBox.Items, etc. From the outside it looks like they are TStrings, but internally they do not use a TStringList but their own descendant. A few examples of classes that descend from TStrings: source\DUnit\Contrib\DUnitWizard\Source\DelphiExperts\Common\XP_OTAEditorUtils.pas: TXPEditorStrings = class(TStrings) source\fmx\FMX.ListBox.pas: TListBoxStrings = class(TStrings) source\fmx\FMX.Memo.pas: TMemoLines = class(TStrings) source\rtl\common\System.Classes.pas: TStringList = class(TStrings) source\vcl\Vcl.ComCtrls.pas: TTabStrings = class(TStrings) TTreeStrings = class(TStrings) TRichEditStrings = class(TStrings) source\vcl\Vcl.ExtCtrls.pas: TPageAccess = class(TStrings) THeaderStrings = class(TStrings) source\vcl\Vcl.Grids.pas: TStringGridStrings = class(TStrings) TStringSparseList = class(TStrings) source\vcl\Vcl.Outline.pas: TOutlineStrings = class(TStrings) source\vcl\Vcl.StdCtrls.pas: TCustomComboBoxStrings = class(TStrings) TMemoStrings = class(TStrings) TListBoxStrings = class(TStrings) source\vcl\Vcl.TabNotBk.pas: TTabPageAccess = class(TStrings) –jeroen

TMS VCL UI Pack is here, the next generation of TMS Component Pack

Since we launched TMS Component Pack back in 1998, it has been our flagship product for user interface controls for VCL based Windows application development with Delphi & C++Builder.
In the past 21 years, a lot happened. Unicode support was introduced, Win64 support added and more recently, VCL got support for (per monitor) high DPI and VCL Styles (including extra VCL styles from the DelphiStyles company). Embarcadero started offering in 2011 the FMX framework for cross platform development for which we meanwhile also developed a large number of cross platform user interface components and it became crucial to differentiate products by technology, like TMS FMX components, TMS FNC components, … and more recently also TMS WEB components…

After 21 years, we thought it was time to better align the VCL user interface components with our other product ranges and naming convention and therefore proudly introduce its successor product TMS VCL UI Pack v10.0. But there is much more to it than a name change for aligning it with other product lines. Internally we also completely moved the TMS Component Pack to a new build process that was already in use for our cross-platform FMX & FNC products.

The benefits are:

  • Moved to a new build & installer generation process allowing more frequent releases, faster rollout of improvements and fixes and also beta builds
  • Builds of full trial versions for all supported Delphi & C++Builder versions
  • In short term we will also submit a version for GetIt to facilitate download & install from the IDE itself
  • Faster migration & support to upcoming new Delphi & C++Builder versions
  • Better install/uninstall experience
  • Consistent & clear product naming
  • Focus on improvements for high DPI and VCL styles support across the entire TMS VCL UI Pack components
  • New components: Kanban board UI VCL control and TableView UI VCL control
  • Updated PDF generation library with new features
  • Keep components backwards compatible with TMS Component Pack v9.x components

A glimpse at what is new:

In TMS VCL UI Pack v10.0, we have not only 2 new VCL components but also several improvements to existing components:

  • TAdvKanbanBoard component, a highly configurable workflow visualization component
  • TAdvTableView component, a versatile & modern supercharged list control
  • PDF generation library improvements such as the capability to add rotated text
  • Support for VCL Styles

What does it practically mean?

Let there be no misunderstanding. We paid the utmost importance to make the step for you as easy as possible while moving the TMS Component Pack to our new build platform. Normally, it should be as simple as uninstalling TMS Component Pack + download and install TMS VCL UI Pack and recompile your applications with the new version. Some notes though:

  • If you use runtime packages, you will need to change the package name dependencies
  • If you use TAdvTreeView, we moved this component from using TCanvas to TAdvGraphics. When opening form files using TAdvTreeView, ignore possible property errors, save the form file and recompile.
  • If you use C++Builder, you will need to change the linked library name references in your project

We have summed up these steps in detail in a file migrate.txt that is included in the TMS VCL UI Pack install folder.

Moving to TMS VCL UI Pack

TMS VCL UI Pack v10.0 is the new product name for TMS Component Pack v10.0. This means all users entitled to get TMS Component Pack v10.0 automatically receive TMS VCL UI Pack v10.0. Also, users with an active subscription to TMS ALL-ACCESS, TMS VCL Subscription or TMS Component Studio receive TMS VCL UI Pack v10.0 automatically.

For your convenience, for a while we will simultaneously keep offering access to TMS Component Pack v9.x.
So, users with an active TMS Component Pack license will get both TMS Component Pack v9.x and TMS VCL UI Pack v10.x and users purchasing a TMS VCL UI Pack license or upgrading to TMS VCL UI Pack will also still get access to TMS Component Pack v9.x. Of course, as it concerns mostly the same components, these cannot be simultaneously installed in the IDE. But if, for one of the reasons above, a migration would require some work on your side to change package name references for example, you can freely chose when to plan this change and continue to use TMS Component Pack v9.x till you have time and are ready to switch to TMS VCL UI Pack.

What’s next

First of all, with our processes streamlined here, we will be even more efficient & productive to roll out new TMS VCL UI Pack versions with new features, new components and improvements more frequently and faster. The new naming convention should bring more clarity as to what technology the product can be used with. Similar work has been started here already for other TMS VCL products and all will get the TMS VCL xxx productname nomenclature in the coming months.

Feedback

Still having questions, comments or feedback? Don’t hesitate to leave a comment here on the blog or contact support for all questions and suggestions or sales for questions related to upgrading to TMS VCL UI Pack from older TMS Component Pack licenses or smaller VCL component bundles. We look forward to hear from you!

macOS 64 bit compile-ready support

Intro macOS 64 bit compilation support has been added to our products. Below is a list of products that are currently enabled to compile for macOS 64 bit TMS FMX UI Pack TMS FMX Chart TMS FMX Cloud Pack TMS FMX WebGMaps TMS FMX WebOSMaps TMS mCL TMS FNC Core TMS FNC Cloud Pack TMS FNC UI Pack TMS FNC Blox TMS FNC Chart TMS FNC Dashboard Pack We continue adding macOS 64 bit support to our other products, and will mention that in the version history whenever an update is released. macOS 64 bit compile-ready support? Our products are prepared to compile for macOS 64 bit, but this is not automatically enabled. Unfortunately, RAD Studio Rio 10.3.2 is an update that uses the same version number as older RAD Studio 10.3.* versions and therefore we have decided to not automatically install for macOS 64 bit, but make it compile-ready. To compile your applications for macOS 64 bit, please follow the steps below. Install/Update one of the products in the above list Update the macOS 64 bit library path with the path to the source files Compile/Deploy your application for macOS 64 bit by changing the target MapView TMS mCL TMS mCL originally has a MapView component that was working in a 32 bit macOS operating system and was then removed from the frameworks due to technical reasons. Now, with 64 bit, you will be able to use the MapView component again. Feedback Please provide any feedback regarding macOS 64 bit compilation support so we can further improve our products.

FNC Code Gems: Helpers for Base64 encoding and decoding

In the last post, I looked at methods to help you get information about connected displays and determine the path name for common folders. Let’s look at something very valuable when you want to convert binary data into a string: Base64 encoding.This is somewhat tricky if you have to consider all the different platforms and frameworks. FNC makes it very easy!

Again, the class TTMSFNCUtils offers awesome methods to get results quickly:

class function FileToBase64(const AFile: TTMSFNCUtilsFile): string;
   
class function Decode64(const AValue: string; 
                        const AURL: Boolean = False): string;
class function Encode64(const AValue: string; 
                        const AURL: Boolean = False): string; overload;
class function Encode64(const AValue: TBytes; 
                        const AURL: Boolean = False): string; overload;  

Not only are there methods to encode and decode strings, there is also FileToBase64 which allows you to retrieve the Base64 string for a file using a single line of code:

LBase64String := TTMSFNCUtils.FileToBase64( 'mydata.bin' );

Ignore the data type of AFile to specify the filename. In VCL and FMX the type TTMSFNCUtilsFile it is mapped to a string. However, for web applications you cannot specify a local file name and the method has to be invoked differently. There is no inverse function for this as it is already a one-liner in Delphi now to store a string or a byte array into a file using TFile from System.IOUtils.

In order to encode a string, call Encode64; call Decode64 to decode a string:

LMyBase64String := TTMSFNCUtils.Encode64( 'testtest', false );
LMyTestString   := TTMSFNCUtils.Decode64( LMyBase64String, false );

Remember, these methods are available for VCL, FMX, LCL, and TMS Web Core.

One Codebase – Multiple Targets

FNC

This week we focused on FNC, with a series of media content, brought to you via Facebook, Twitter, blog posts and other media channels. We wanted to focus on what FNC is by highlighting each framework and its corresponding operating systems individually. Here is a sample of what this looks like for the WEB.

We plan on using this for communication, promotion, technical articles, and we believe this will allow you, as a customer, have a better understanding on what FNC is. Below is an overview of what FNC offers, and what it can potentially mean for your application.

TMS FNC Controls can be simultaneously used on these frameworks:

  • VCL
  • WEB
  • FMX
  • LCL

TMS FNC Controls can be simultaneously used on these operating systems/browsers:

TMS FNC Controls can be simultaneously used on these IDE’s:

One Codebase

With FNC, we aim for one code base, that can be re-used on all the supported frameworks and eventually target multiple operating systems. We started with FMX and VCL, and thanks to the high level of abstraction we added LCL support which gave us access to Unix operating systems. Recently, we have added WEB support as well via TMS WEB Core. As an example, we have created an FNC overview demo to demonstrate the “one-codebase – multiple targets” principle.

We are currently also working very hard on a BETA of FNC, which brings a lot of small improvements and fixes, but also brings 2 new components: TTMSFNCPDFLib and TTMSFNCGraphicsPDFIO. In case you missed the blog post demonstrating these 2 components, check out the blog post at the following URL: https://www.tmssoftware.com/site/blog.asp?post=560. The blog post focusses on creating a report in PDF completely generated client-side in the webbrowser. It shows how to mix custom PDF content and existing FNC components and of course also works on the “one codebase – multiple targets” principle explained in this blog post.

We want your feedback!

Please feel free to leave a comment, send us an email with suggestions on this approach and what we can improve in our communication. We want you to get a smile out of your application, because a smiling application, is a smiling customer!
