A vendor distributes trial code that needs to be linked as runtime packages. They provided instructions thusly: enable the Project --> Options...--> Packages --> Runtime Packages --> Link with runtime packages IDE option However, in Delphi 10.2.2 (2004) the Project -> Options panel has a "Packages" option at the left, but selecting it only displays Design packages. There's nothing there for runtime packages, and no way to say "Link with runtime packages". I've seen it before, but I cannot find it anywhere now. Can anybody else see this? Or did it move somewhere else?

Hello, I will have a question from one of my clients. I proposed a study to migrate their Delphi heavy client application to 3-third party applications with a DataSnap server. But my client wonders about the resistance of such an architecture to the load. It is an accounting application and a human resources application. Depending on them, there may be up to 800,000 postings per month (i. e. JSON REST HTTP transactions between clients and the server). Knowing that these entries will be spread over different countries with time differences and therefore at different times, generally about forty customers (thus 800 0000 / 40) over one month, every day. so 700 daily entries * 40 in parallel (not necessarily at the same time, but possibly) I would like to reassure them by explaining that this load is held by DataSnap without any problem (this obviously depends on the configuration of the web server I guess). Is DataSnap limited in number of parallel connections? What about the number of su

Hello, I have a question that is more complex than I thought On a Delphi software with a mail function, the body is a TMemo and it's possible to add attachments. the mail can be sent with SMTP (IdSMPT) or through MAPI (JvMail). Now I have a request for HTML Support...for the SMTP part it's not a problem, but MAPI do not know HTML, especialy with embedded images and attachments. I've tried to create an .EML file, but ShellExecute() open it as an incoming mail, not a mail to send. So is there an easer solution than adding an IMAP request to put the sent mail in the outbox ? Of course I don't know the mail software that will be used (ThunderBird, Windows Mail, Outlook...), that's why MAPI/ShellExecute looks great at first. Thanks.

Very interesting article on Unicode-code. http://rvelthuis.blogspot.fi/2018/01/strings-on-other-platforms-than-32-bit.html?m=1 We really should get Fast-code project up and running cooperation with Embarcadero. I think there is lot in Current RTL and VCL/Fmx frameworks that have room for optimization. Without direct cooperation will be hard to get code through. Sure there could be some Unit that patches original code, but getting them to Embarcadero code base is the way to go (I think). Also some Embarcadero sponsored prices would be good for motivation (for some) We can make QC reports but ready to replace code with unit tests and speed measurement projects (etc) would be way better way. I think it should focus on Unicode, 64bit code. But in anyway from lowest levels towards the GUI.

Originally shared by Thomas Mueller (dummzeuch) When you google for TSpeedButton and Focus a lot of hits are where people ask how to set the focus to a TSpeedButton and the answer of course is, that it isn’t possible because TSpeedButton descends from TGraphicControl which does not have a window handle… http://blog.dummzeuch.de/2018/01/28/fake-tspeedbutton-based-on-a-tbitbtn/

Is there a component like TSpeedButton that can receive the Focus? TSpeedButton cannot because it is derived from TGraphicsControl and not from TWinControl. But since the question "How do I make TSpeedButton receive the focus?" must have been asked a Gazillion times over the years, I can't believe that nobody has written a component that solves that problem. But my Google fu left me. What I need is TSpeedButton's ability to stay down until pressed again, but it should take the focus and be pressed with the space bar. This is about VCL only.

I recently added a FireMonkey component to CEF4Delphi. CEF4Delphi is an open source project to embed Chromium-based browsers in applications made with Delphi but until now, it only had VCL components. It's my first FMX component and it was developed using Delphi 10.2. It only works in Windows and I'm 100% sure it's not compatible with some older implementations of FireMonkey. I would be grateful if you could test the FMXExternalPumpBrowser demo and make some comments in the forum to improve it. Thanks! https://github.com/salvadordf/CEF4Delphi https://github.com/salvadordf/CEF4Delphi

Does anybody use tabs in the code editor? If yes, how do you do that? In all my installations the following happens: procedure bla; begin blub; pressing enter results in procedure bla; begin blub; So, the tab remains, but the new line is indented by spaces. I have enabled Tools -> Options -> Editor Options -> Source Options * Use tab character * Show tab character * Show space character The example is in Delphi 10.2.2 but I have experienced the same behaviour in Delphi 2007 and XE2.

iOS Debugging Issue Hi I have 2 Macs for FMX/iOS development. One has High Sierra (10.13.1), the other has Sierra (10.12.6). They both have the latest XCode and PAServer (10.2.1.10)) on them but only the Sierra Mac supports breakpoints from RAD Studio. The little blue dots in the editor gutter don't appear and any breakpoints are immediately disabled. It all works as expected on the other (Sierra) Mac. On the non-working Mac, I don't have to supply my password when I start PAServer which seems unusual. Anyone seen this before? Cheers Vince

Hi, Can someone give me a hint on what can I check to detect the exact problem with Delphi Tokyo 10.2.2 (latest build)?

The connection to PAServer is OK Notes: - I didn’t compile anything for OSX before with this VM. - I can compile to Linux without issues (also using FMXLinux) Thx

Hello all. I'm developing a Firemonkey application where I have a (portrait mode) fullscreen PDFs slideshow, using fmx animations and effects to see a nice result. I would like to be able to show/replicate this fullscreen application also in a vertical - portrait mode - TV (tipically a 40"), and the goal should be to get this without using cables. I've goggled a lot for delphi examples, blog posts, etc. without a real help, except a nice Steffen Nyeland 2014 example on how to start a youtube video from a desktop application using a Chromecast dongle. My feelings are that a Chromecast could be a road to explore. Any advice on how to pratically implement this type of PC to TV "application cast"? Thanks Marco

I just thought of how I can improve (refactor?) some of my panels. In one of my projects I have 200+ panels to organize layout (on various PageControls) and about 20 of them are used to split view for side by side view - so I set in the ParentPanel OnResize: Panel.Width := ParentPanel.Width div 2; (and Panel has Align = alLeft and the other Panel has Align = alClient so they split the ParentPanel view) Simple, it works OK. The problem is that each of this panels need to have this Width code in their Parent OnResize and I set this in Object Inspector. And is annoying to track down which panel has this set and which doesn't. So I wanted to simplify this by extending the TPanel: TPanel = class(Vcl.ExtCtrls.TPanel) private FSetChildPanelWidthAsHalf: boolean; // Enable Width div 2 FChildPanel: TPanel; // Set which Panel get set Width div 2 protected procedure Resize; override; public property SetChildPanelWidthAsHalf: Boolean read FSetChildPanelWidthAsHalf write FS

Hi everyone, I am writing object classes to describe aspects of patients in a healthcare app and am bogged down in writing the database connectivity to Firebird. Lots of lines of code getting and setting data to and from class fields and database fields. I want to automate this. Of course the solution is to use an ORM or even MORMOT but that's a whole new learning curve (especially MORMOT) and I want to minimise 3rd party components, and also maintain compatability with Lazarus (I know MORMOT and TMS Aurelius work on Lazarus too). Third party components make for Delphi upgrade hell. So prefer and would be happy with generic plain code, in this case to just automatically parse a class's fields, and then database table’s fields and with a given stringlist of associated field names then shift the data in one direction or the other. Adding or removing fields to the class and database would just require adding or removing the field names from the stringlist. Has anyone do

I've found another TMemo rendering oddity that I wonder if anyone had come across before, or could help with? I've had a user report of a bug where Arabic characters aren't showing in a TMemo set to ControlType = "styled". Before it's mentioned, I know that Firemonkey doesn't support R-to-L rendering and I'm not looking for that (yet), plus for other reasons, I need to use the Styled memo rather than the Platform one so that's unfortunately not an option either. A quick way to reproduce is of you put a few Arabic characters into a TMemo at design time and run it on iOS it renders them as spaces. It renders fine on Android and Windows but not iOS. I've been debugging and tracked it down to a display issue when rendering the glyph for the characters within FMX.FontGlyphs.iOS.pas. The internal data structures store the correct character to be rendered but its as if the glyph bitmaps for late unicode characters (1333 in this case) aren't correc

Question: I run a Delphi application from the IDE (Run without Debugging) and then run it by by clicking the executable from Win Explorer. There is consistently, a 25% difference (10 Mbs) in the memory reported in the Task Manager. Any idea what might explain this difference? (no run parameters specified in Delphi). And an observation. VS code with just a couple of small text files loaded has roughly the same memory footprint as the Delphi IDE with a large project addines etc. loaded!

Has anyone come across this issue and know of a fix or workaround? If I drop a TMemo onto an FMX project form and run on iOS, it works fine except using the cursor keys on my iPad hardware keyboard. I've had a few reports of this from users with other hardware keyboard types too. https://quality.embarcadero.com/browse/RSP-16066 Changing Memo.ControlType to Platform (rather than Styled) fixes this issue but introduces a number of other problems for my users so I need to stay on the Styled control in this case. I've debugged and noticed that [UIKeyboardImpl handleKeyEvent:executionContext] is triggered but this is next dispatched to Delphi, and none of the internally accessible Delphi library methods are called. It's fine on Android and Windows. I can't seem to get any further than this so wonder if anyone could offer advice how I might be able to work around this aside from switching to Platform styling?

Nice example of anon methods for functional programming.

Personally, I think this is really cool! You don't need to know the details of this first function, just see how the others use it. Note that TProc is pre-defined in one of Delphi's units. Other than that, nothing else needs to be defined to make this code work. It's all right here.

Why does Delphi complain about deprecating a setter method, but not other methods. I'm using XE3, and Delphi doesn't support deprecating a property, so I thought I would deprecate the setter method. But Delphi doesn't like that either. It is perfectly happy with the "Procedure Text;" as deprecated though??? TtiIntegerListItem = class(TtiBaseObject) private FValue: Int64; // fails to compile procedure SetValue(const Value: Int64); deprecated 'The AValue property is deprecated. Please use the Value property instead.'; // this one is accepted though procedure Text; deprecated 'use Value() instead'; public constructor CreateCustom(AValue: Int64); property AValue: Int64 Read FValue Write SetValue; // Delphi doesn't support deprecated here like FPC does. property Value: Int64 Read FValue Write FValue; end;

I've got a couple of issues with GetIt in Tokyo 10.2.2 (2004) I installed CodeSite Express, but it didn't set up a path anywhere to find the files. I put this into the global Library Path, but it's not working: C:\Program Files (x86)\Raize\CS5\Lib\RX10.2\$(Platform) EDIT: I just noticed it's already there with \win32 instead of \$(Platform), but it still isn't finding the units. EDIT: well, after a couple of full builds, the compiler figured it out. Never mind. Second, the BeyondCompare IDE addin is still not working. I thought it was fixed. As an aside, I've got a license for BC4. Does this come with something that can be installed into the IDE? Or is the IDE addin just something they put out for use with Delphi?

My Delphi is Enterprise - Berlin The event (into the Delphi COM server) has string parameters and if the event is triggered with blank string values (empty strings '')(all or some of them), it will not be fired in C# program because an exception is raised. The raised exception message is: Invalid pointer. but... There no such problem if the clients application is a Delphi application. The Delphi client application works perfectly. If the string parameter has only one character also, the event will be fired into the C# application without an exception.

Castle Game Engine 6.4 was just released! It's an open-source cross-platform (desktop, mobile) 3D and 2D game engine using modern Object Pascal. It is NOT yet compatible with Delphi (only FPC / Lazarus for now). But I'm posting about it here, because I'm working on making it comptible with Delphi in the next release. In this engine version (6.4), base units already compile with Delphi (although nothing visual yet, only console tests), and our new vectors API is Delphi-compatible (using advanced records), and we use Delphi-compatible Generics.Collections throughout the engine. I want to achieve full Delphi compatibility with the next release (6.6).

Meanwhile i have done a lot of tests but i can't find the bug in my code ... there is nothing special. Does someone has also an webserver with tidhttpserver on tokyo 10.2.2 + sessions working? Possible to test the site over android handy?

I'm using Delphi XE3. When I compile projects with FPC, the FPC compilers lists the files that it compiles (new or recompiled units). When I compile projects with Delphi XE3 the Messages window only shows the dcc command line string that is use and "Success" at the end. Is there a way to let it show me what files in found that needed to be recompiled - so I can be certain it picked up what it needed to.

Nice simple bug in 10.2.2 Right click on a folder node in Project Manager, select "Show in Explorer", precisely nothing happens. Right click on a file, and the Folder containing the file opens. Works OK on 10.1

I find it so sad that Borland/CodeGear/Embarcadero people can't fix one liner that I first reported for D4 >:-( http://www.17slon.com/blogs/gabr/TDM/tdm44-gp.pdf No idea what happened with the original bug report, probably got lost at some database transition or somebody marked it "works as designed". Dejan Crnila ran into the same issue last year and proposed the same solution as I did 18 years ago. https://quality.embarcadero.com/browse/RSP-19360 This bug is so old that it can vote in most (all?) European countries. Please vote on the issue. Thanks. http://quality.embarcadero.com/browse/RSP-19360

What are the size restrictions for the VCL controls like TPanel and TPaintBox.? Are they documented anywhere? I'm talking about placing these on a TScrollBox, so the screen size is not a limit. The maximum width of a TPanel on my computer seems to be 2^15 pixels, but I couldn't find any documentation on it, so it might even depend on the Windows version or the graphics driver.

I'm creating my first class - it will be handling 'running of selected action/s' and action will run is based on 100s of options. I have around 300 actions/options grouped in 20 categories. So, I was thinking of having 20x overloaded procedures that will accept different parameters - that control running actions. Because of so many options, I was thinking of creating enums and have them as input parameters - this way I will be able to see in code completion/insight what kind of parameters I need to use to control running specific action. I hope this simple example shows what I' working on: // example of categories and actions TSuperActions = (saNone, saSuperProject, saSuperGroup, saSuperSubGroup); TMajorActions = (maNone, maClearData, maDeletAllData, maRepairData); TMinorActions = (miNone, miDeleteRecords, miPrepareInfo, miPrepareForExport); RunActions = class ... public ... procedure RunAction(aProjectID: integer; aSuperAction: TSuperActions = saNone); overload; proced

Playing with my TGraphicPanel (a parented TGraphicControl) I've think about a feature that could be nice to have, an AlignWeight property to priorise controls alignments. The concept is simple, by default, a value of 0 do not change the behavior. If the AligWeigth of a component is higher, then it is aligned first. It can also define the align order of a set of "alLeft" components regardless of it's actual position.

Fellow Delphi Developers, We continue to improve our High-DPI demos for StyleContols VCL. Now you can see our updated Ribbon Analogue demo with new VCL Style "Windows10 Clear Day" from DelphiStyles.com. Demo uses: 1. TscToolPager control (ribbon analogue control) with different controls from the package. You can set TabsLeftOffset, TabsRightOffset and put any controls from left and right in tabs area. 2. TscStyledForm component to add buttons in form caption + improved styled form. 3. TscGPImageCollection and TscGPVirtualImageList components for all images in cotnrols and forms. With these components you get HQ scalable images in controls. 4. Custom dropdown form with TscAppPager control as application menu. You can create any custom form as dropdown window and link it to the TscButton control. StyleControls VCL Home: http://www.almdev.com

Tip: Use Ctrl+W to select content in the IDE code editor. Place your cursor some random piece of code, preferably deep in code that have nested blocks. Press Ctrl+W. Repeat, and repeat while watching the goodness progress. This tidbit was shared by Jim Mack in a comment in the FB Delphi group. Edit: The feature was introduced in Berlin 10.1 The feature struggles with Unicode characters in code and strings. Those of you that use national characters in your strings or code (such as Cyrillic, Greek, or Chinese) that also misbehaves, should add a comment / example to the QP issue and vote on it. https://quality.embarcadero.com/browse/RSP-19787

Looking for some simple answers to what may not be simple questions. Hoping to use DevExpress grid export for Excel, and the DevExpress Printing System for PDF. Been exploring the demos, and also on youtube, but I need to know, on the Printing System, can it help me if I need data in the report from multiple grids? And from other sources? In particular, I must present a standardized page header and footer, and in some cases, formatted data from multiple grids. We have been using ReportBuilder for this, but it is difficult on that path to exploit advanced features of the DevExpress Quantum Grids.

When I click on "I already have a product serial number" the installer don't allow me to click on "Next" button, only if I close it and go for "I have a trial ..." something like :(

The new GDI scaling introduced in Windows 10 Creators update is quite amazing. ( https://blogs.windows.com/buildingapps/2017/04/04/high-dpi-scaling-improvements-desktop-applications-windows-10-creators-update/ ). Just try it on the Delphi IDE if you work on a High DPI monitor and enjoy the difference. You need to right-click on the executable or the shortcut, select Properties and under compatibility check "Override high DPI scaling behavior" and select System (Enhanced). You can also make your DPI unaware Delphi apps to use GDI scaling by default by adding a custom manifest that includes the following: http://schemas.microsoft.com/SMI/2017/WindowsSettings "> true It is almost as good as DPI awareness without the conversion effort. https://blogs.windows.com/buildingapps/2017/04/04/high-dpi-scaling-improvements-desktop-applications-windows-10-creators-update/

Hi all, is receiving multipart/formdata (+file uploads) with Tokyo + Indy-tidHttpServer simplier than in past? Has someone a working "Upload Image to idHttpServer" demo? In 2014 indy had no automatic decode for that, possible that something has changed and now indy can decode?
