    Hello RAD Studio Experts,

    I feel that RAD Studio Professional is a good choice for cross-platform IDE.  It's price is around EURO 2,300.  As to such a super complicated software, I can say this price is fair and reasonable.

     

    When it comes to security fixes, how much do we have to pay for a yearly subscription for a RAD Studio Professional Edition?

    If I stop subscription, do I have to buy a new license in order to get the security fixes?

     

    Thanks for your attention.  :classic_rolleyes:

    So, you wen't for Delphi or C?

    There are also other choices:

    LabVIEW - great for creating dashboards.  It also has a built-in free-of-charge MQTT plugin.  License fee is acceptable for small poor developers. :classic_blush:

     

    Qt - is also able to create nice dashboards.  License fee is US$10,000 per seat per year.  Unless you are Lockheed Martin or BAE, you may want to avoid it. :classic_laugh:

    This is probably the result of an unstable Delphi installation.  There are no similar issue reports in the P4D issue tracker.  What happens if you open the packages one by one instead of opening the project group?

    Hello,

    I tested them and just the same situation - freeze up the whole Delphi software.  :classic_huh:

    Ok, then,

    I installed Python4Delphi manually without choosing the auto compilation option.

     

    Then, I opened the target project group, chose the module with a bar on it and then secondary clicked on it trying to show its menu but the whole delphi window hung up.  I had to kill it from within the Task Manager.

     

    How do I correct it?  :classic_huh:

     

    I already have a WinPython 3.8 installed and registered on my Windows 10.  :classic_huh:

    Who can help to correct this?  :classic_huh:

    Hello,

    When I install python4delphi by running MultiInstaller.exe, it shows error like "Your Delphi version does not support COMMAND".

     

    What should I do to correct it?  :classic_huh:

     

    My version is Delphi Community v10.4.2.  Thanks for your attention.

     

    And which python version does it support?

    BLE support is built into Delphi.

     

    If you have 1000+ remote "smart sensors" that are sending data back to a data collection server, then Delphi can be good for managing the collected data and as a "Dashboard" of sorts to control everything.

     

    COOL!

    These stuffs are good enough!  :classic_cheerleader:

     

    LabVIEW is also a good choice but no BLE support built-in.  Its native instrument interface is good!

    Hi again Tim. I see in another thread that you've installed Image32 as part of SVGIconImageList. I suspect the problem lies there and you may need to temporarily uninstall 
    SVGIconImageList and reinstalling Image32 before compiling the FMX sample apps. Otherwise, I'm not aware of anyone else having problems with compiling the samples.

    Angus,

    If you can make a GitIT package, it will be much better.  :classic_unsure:

    Up to now, I am quite happy with Delphi v10.4.2 about its cross-platform GUI development ability. :classic_cheerleader:

     

    About its price.  Professional version should be acceptable.  Try to compare it with QT Creator and Visual Studio 2022.  You may find that RAD Studio Pro version is even cheaper.

    QT Creator costs you US$1,000.00 per month to be paid yearly.  It sums up to more than RAD Studio Architect! :classic_blink:  If you are a C++ fans, I would suggest Code Blocks + wxwidget + wxsmith which cost you nothing.

    Hi Tim. What version of Delphi are you using? Older versions of Delphi don't contain the FMX library.

    I am using the Delphi Community v10.4.2.

     

    I can run the bouncing green ball project, however.

     

    I am totally new to this software and catching up quite well.  I guess it can help me to build a very large dashboard GUI. :classic_cheerleader:

    This one from IEEE is more authoritative

    https://www.computer.org/publications/tech-news/trends/8-best-video-file-formats-for-2020/

     

    You should choose a file format based on your video quality requirements. The video should achieve the required quality, but no more than that. High-quality videos are hard to download, convert, share and manage. Plus, you need to take into account how you want to view the video files. Not all browsers, programs, and devices can play a specific video format. 

    Before choosing a video format, consider the following cases:

    • For online videos choose a file format that most web browsers support. This way, your video will be played natively on the browser. MP4 and WEBM are browser compatible video formats.
    • For home video recordings, choose a format with high quality video good chance of being usable in the future. Open source file formats are more future-proof than proprietary formats that are controlled by enterprises. MP4 or AVI formats are a good fit for that category.
    • For Windows applications, choose a format that is compatible with Windows. WMV is a good choice In this case.
