Fault is mine : no problem at all

Hi there,

I need to extract evry filed in TAlphaColor. Here's my sample code :
 

var Red, Green, Blue, Alpha: byte;
begin

  paletteColor:= TAlphaColorRec.Create(TAlphaColors.Blue)

  Alpha := paletteColor.A;
  Red := paletteColor.R;
  Green := paletteColor.G;
  Blue := paletteColor.B;

My problem is that Alpha is OK (255), but other fields return 0

An idea ?

Runs fine : thanks a lot

Hi there,

As an exemple, in a json, I push some data with accentuated chars like : é

They appear in TJsonObject.ToString as : \u00E9

I'de like to convert those codes, into TJsonObject.ToString, to their original representation \u00E9 --> é

I can't find any way to that. An idea ?

I have a TImage in which I use the KeyDown event.

But if I set the DragMode in Automatic, Keydonw is no longer fired.

An idea ?

I've found it : thanks a lot

Thanks a lot. I'de like to have a class inheriting from TButton, under FMX Crossplatform.

How may I set the controltype in this case ?

Hi there,

I've now spend somme hours to try to change the Background Color of a TButton, or TSpeedButton, at run time. But no way !

An idea ?

Very technical answer : it helps a lot. Thanks

I'm not strong at threads, but have to use them due to crossplatform app. So :

TThread.Synchronize is made to display something in the gui, surely. But I often prefer TThread.ForceQueue.

After you have a lot of timers. In the past on Windows, that wasn't a good strategy. I'd prefer one timer with a switch.

After you can use, I think, tthread.CreateAnonymousThread, but when you want it to do something to be displayed, you have to Synchronise, or ForceQueue, from this Anonymous thread.

Also, if you have a variable in the main thread, and you want to change its value from Anonymous, you have to do it in a Synchronyse, from th Anonymous.

And to finish, be careful of Android, which threads are a little bit differnet from the other plateforms.

Hope this helps.

Yes it does for me...

Runs fine. Thanks a lot !

No way for me to have the

TFDPhysSQLiteDriverLink

 with those uses... Can't find library

My pleasure

Of course !

Thanks a lot

Hi there,

I've installed Athens, so of course I lost all my configuration, and above all, the types of messages printed in the output frame.

I do not need all these informations, that "mask" my own informations. So in previous version I've arrived to control the output, but I can't arrive to do it on Athen.

Where do I decide what appears in the output frame ?

Typically, all the std messages during the use of the software are too mutch to me. I'd like to output only the messages I decide to output.

My app runs with sqlite and uses 2 files, stored in deployment page for MacOs like that :

libcgsqlite3.dylib in Contents\MacOs

libcgsqlite3_fde.dylib in Contents\MacOs

I have a Notarization error :

   {
      "severity": "error",
      "code": null,
      "path": "intelli7.app.zip/intelli7.app/Contents/MacOs/libcgsqlite3.dylib",
      "message": "The signature does not include a secure timestamp.",
      "docUrl": "https://developer.apple.com/documentation/security/notarizing_macos_software_before_distribution/resolving_common_notarization_issues#3087733",
      "architecture": "x86_64"
    },

Any idea will be very appreciated...

Solution

The pb was that one of the libs had a path like that : c:\...\;

It needs a path like : $(BDS)\Redist\osx64\

So need to edit myapp.deployproj to change the path.

I don't know

I think it depends on the OS target.

On Windows, I do not add any file

On Android, I add lib-native-activity.so

On MacOs I add libcdsqlite.dylib and libcrypto.dylib

On IOS I add ... nothing

On Linux I add ... nothing

But I'm not sure all these libraries concern SQLite

[SOLVED]

I've put on app boot a on the main form :

TFDPhysSQLiteDriverLink,

with the property :

EngineLinkage -> sIFDEStatic

Maybee an idea do do that from code ?

Thanks for your replies.

I've read the FireDAC SQLite Version Update  and I understand I have to use option 3 : Continue using SQLite 3.31.1 or previous versions with FireDAC encryption (FDE).

But I didn't see anywhere how to do that (sorry, it's not my best expertise).

What's the code I need to put and where ?

Hi there,

I've an app which runs fine on Delphi 11, using crypted (aes-256) SQLite db, throught FireDac.

This code no longer runs under Delphi 12.

An error is fired from FireDAC.Phys.SQLiteWrapper.pas, procedure TSQLiteDatabase.Key(const AKey: String);, line 2119 : if Assigned(Lib.Fsqlite3_key) then begin...

It seems that Lib.Fsqlite3_key is not assigned.

Any idea will be very appreciated...

Thank you Alexander. I will not hesitate one second...

It helps a lot. Thank you

Great. Thank you

Very interesting. Thanks a lot.
