I need to convert my adobe air application (using Flex 4.6.0.) into 64 bit desktop application (Mac OS and Windows).
Could you explain how to do ?
Indeed, macOS Catalina (macOS 10.15) won't support 32 bit apps !
So I need to find an alternative quickly.
Thanks for helping.
Best regard
In order to update to 64 bit, you will have to update your sdk. 4.6 version is very old (2012 maybe?).
First update your SDK to AIR 32.
Then you can use tag <architecture>64</architecture> in the application.xml file to force 64bit compile.
This works both in windows and mac for desktop apps.

With Xamarin.Forms I'm developing a mobile app. In Android I get this succesfully running on a device. I succeeded to create an app package from the UWP project and install it on my own Windows 10 PC. This is also my developing machine, so it's in Developer Mode by default. So it runs here without any problems.
My purpose is to get it running on Windows 8.1 Pro (tablet size). It just needs to consume the app. When installing the app by using the script, it's throwing the error that no developers license is found. On this device I didn't found anything to put it in Developers Mode, but it seems me that this is not needed, because it only consuming the app and no developing will take place on it.
It's is an internal app, so no need to place it on the Windows Store.
So my exact question: how can I install this app on this device without setting everything up for a Developer?
The answer would be no. Windows 10 has more new API and concepts that are not available on Windows 8.1. UWP app will not backward compatible to Windows 8.1. But WRT app will be Upward compatible to windows 10. It means that the windows 8 store app could run in windows 10. for more please refer Move from Windows Runtime 8.x to UWP.
I have downloaded turbo c++ 4.0 . It is not causing anything error. But the application I made in c++ is showing error outside of the IDE that: "this app can't run on your PC, to find a version for your PC check the software publisher". I have windows 10 64 bit, turbo c++ 4.0 x64
Thanks in advance!
Turbo C++ creates 16bit apps. 64bit versions of Windows cannot run 16bit apps directly. 32bit versions can, though. For 16bit apps, you can try installing DOSBox or other DOS emulator that can run 16bit code on 64bit systems.
The answer is that we have to download DOS-BOX or DOS-emulator and navigate to the executable file then open it will work there on the DOS box window and If the program is graphics type then just copy the EGAVGA.BGI to the folder in which exe file is located.
Thank you
I have developed a custom media player that works on Windows 7. I used QMediaPlayer, QVideoWidget and QMediaPlaylist classes. I need to port the app to Linux. Do these classes also exist for Linux? Do they come automatically when installing Qt?
I tried copying the project to my Linux partition and recompiling but it can not find the headers.
Check weather the major version of Qt is the same on both platforms.
Seeing your description, I believe you are using an older version of Qt on the Linux machine as compared to the Windows machine.
Hope this helps.
I originally installed Qt 5.20 with Qt Creator 3.0 on my Win7 64 bit machine and it worked flawlessly. Then I wanted to install it into a Win7 32 bit virtual machine (using VirtualBox). In the VM I start off on the qt-project.org site and download a version. I've tried both the Qt Online Installer for Windows (13 MB) (Info) link and the Qt 5.2.0 for Windows 32-bit (MinGW 4.8, OpenGL, 689 MB) (Info) link. Both installs work and I can compile a simple Hello world demo. However, when Qt starts the Qt Welcome Mode is just a transparent window showing the contents of the desktop. If you change modes and go back to the Welcome mode it will then just show the contents of the previous mode. I would like to have access to the examples and tutorial links.
I'm using VirtualBox 4.3.6 and I have Guest Additions Installed. I'm running a copy of Win 7 Ultimate. The VM is very clean, it has Chrome installed, the latest Win updates and MS Security Essentials and that's about it. The virtual hard disk (vdi) has about 50 Gigabytes of free space after the install.
I've tried
1. turning off Windows Firewall and MS Security Essential real time protection.
2. running as administrator.
3. running in xp SP2 and SP3, and win95 compatibility modes
4. running with Aero disabled
Nothing has helped. Any suggestions?
I't a known bug. The Oracle Virtual Box has problems rendering the QML apps/widgets. And the welcome screen in QtCreator is a QML widget. https://bugreports.qt.io/browse/QTBUG-34964
Workaround
Start QtCreator with -noload Welcome argument, and later in Help > About Plugins... menu disable "Welcome" for good.
As mentioned here, the solution is to do the following:
In Qt Creator, go to Help -> About Plugins...
Uncheck Qt Creator --> Welcome
Restart Qt Creator
Worked for me.
Is it ok to develop ASP.NET web applications on MacBook Pro ?
.NET is only available for Windows. There's the Mono project, which is not affiliated with Microsoft, which aims to create an open source .NET runtime and developer tools, usable on *NIX (including Mac OS X). If you want to develop .NET applications under Mac OS, this is your only choice.
Speaking of a MacBook though, you can install Windows on it using Boot Camp or run it in a virtual machine and develop in Visual Studio like on any other Windows box. And this is ok, I don't think anybody will confiscate your Mac for doing so.
If you have Windows running on the Mac then it is OK.
Another way is to use some .NET IDE for Mac (e.g. MonoDevelop)
New from Microsoft, IDE for Mac, Linux and Windows: https://code.visualstudio.com/Download
The best method to do that would be to install windows 10 with bootcamp and then install .NET . The steps involved are pretty straight forward. Just open bootcamp and create the partition and select the ISO of windows. Once installed, tap the options key on boot to boot to windows. If everything is smooth, you can continue the development, else, just open bootcamp again and delete the partition.
