can I ask? the tthreadedqueue it's reliable in delphi 12.3 latest release? or do you suggest omnithread queue? about dictionary same question, or do you suggest spring4d? or other libraries are better than default rtl?

hi, I have a windows service where I dispatch a custom thread pool, dynamic, using IoCompletionPort api, then I have a component where methods should be called within the servicethread, my question is, do you know if servicethread.queue it is reliable? is this the best method to post things to the main thread in a safer way without incur in race conditions as deadlock? example, this code is called within a thread: TServiceThread.Queue(Service.ServiceThread, procedure begin dothings end); kind regards

hi, I like to do remote debugging, I have installed PAserver 23 (from Delphi 12.2 paserver folder) into remote vps, then I have copied the \bin\rmtdbg290.exe to the paserver remote folder updating it, have done the profile manager for windows and paserver is connecting ok firewall ports open both paserver and remote debugger I obtain this error from delphi ide: can somebody help me how to obtain remote debugging of windows vcl? thank you

sorry, it works needs open the firewall on remote side bcz many processes dispatch many ports also https://docwiki.embarcadero.com/RADStudio/Athens/en/Installing_a_Debugger_on_a_Remote_Machine kind regards

there is a generic all in one https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#visual-studio-2015-2017-2019-and-2022 installing this solved, probably db clients dll are binded to ucrt so needing this

I had a similar problem with firedac mysql solved installing visual c++ redistributable

question do you remember the good old https://fastcode.sourceforge.net/ ? (2007 project) I asked chatgpt to convert asm32 to asm64 delphi, look at this example: procedure MoveJOH_SSE2_10(const Source; var Dest; Count : Integer); asm cmp ecx, TINYSIZE ja @@Large {Count > TINYSIZE or Count < 0} cmp eax, edx jbe @@SmallCheck add eax, ecx add edx, ecx jmp SmallForwardMove_10 @@SmallCheck: jne SmallBackwardMove_10 ret {For Compatibility with Delphi's move for Source = Dest} @@Large: jng @@Done {For Compatibility with Delphi's move for Count < 0} cmp eax, edx ja Forwards_SSE2_10 je @@Done {For Compatibility with Delphi's move for Source = Dest} sub edx, ecx cmp eax, edx lea edx, [edx+ecx] jna Forwards_SSE2_10 jmp Backwards_SSE2_10 {Source/Dest Overlap} @@Done: end; {MoveJOH_SSE2} chat gpt rewrite this in 64bit: procedure MoveJOH_SSE2_10(const Source; var Dest; Count: Integer); asm cmp r8d, TINYSIZE // Compare Count (R8D) with TINYSIZE ja @@Large // If Count > TINYSIZE or Count < 0, jump to @@Large cmp rcx, rdx // Compare Source (RCX) with Dest (RDX) jbe @@SmallCheck add rcx, r8 // Adjust Source address: Source + Count add rdx, r8 // Adjust Dest address: Dest + Count jmp SmallForwardMove_10 // Jump to small forward move @@SmallCheck: jne SmallBackwardMove_10 // If Source ≠ Dest, use backward move ret // If Source = Dest, exit (compatible with Delphi’s Move) @@Large: jng @@Done // If Count < 0, exit (compatible with Delphi’s Move) cmp rcx, rdx ja Forwards_SSE2_10 // If Source > Dest, use forward move je @@Done // If Source = Dest, exit sub rdx, r8 // Adjust Dest address: Dest - Count cmp rcx, rdx lea rdx, [rdx + r8] // Restore original Dest address jna Forwards_SSE2_10 // If no overlap, use forward move jmp Backwards_SSE2_10 // If overlap, use backward move @@Done: end; opinions? does this make sense to you? can we take the winners of fastcode 32bit and convert them in 64bit so easily? chatgpt then owns the copyright?

indeed the quality of the system rtl of D12 is outstanding

I used libraries from JsonDataObjects, DataSet.Serialize TestWebbroker.zip

I feel dumb, want edit first post, can't find how to want erase one post, seems impossible! 😕

thank you

I don't find where to rename the topic 😕

how to?

hi, can I ask your opinion about this JSON library to adopt? As much as there are good repositories for Delphi, in the last period I feel comfortable with this JsonTools (I handled all the blobs correctly from many devices where other libraries gave me errors in parsing) https://www.getlazarus.org/json/ https://www.getlazarus.org/json/tests/ (all test passed) btw. I am a loyal Delphi customer, I don't want to advertise Lazarus 🙂
