I'm looking for a small component/library to just draw some vectors, perhaps add some predefinded shapes and load some bitmaps, save everything and perhaps export to bmp/png, whatever. I want to be able to "paint" by hand and "paint programatically". I found littleearth/draw-objects: draw-objects (github.com) (Update to TDrawObject Components (angusj.com)) In a previous search I found something similar, but I can't seem to find it anymore. Perhaps someone has an idea? I don't think I need a fullblown CAD solution...

If you would be so kind to point me into the direction where I can find GR32_Objects I could evaluate it. But it is not part of the Graphics32 repository. From my google search it looks like it was an add on by AngusJ, who concentrates on Image32 now. But I fail to find a source. But a couple of hundred lines are indeed too large an effort if it means reinventing the wheel. That's why I asked first for a finished solution. I can still invent the wheel if it's not invented yet, or I need square wheels for whatever reason. The TMS component linked by SwiftExpat is an option, but it looks like that the Delphi Area Simple Graph Component (despite being abandoned by its creator) is sufficient for my needs.

Thanks. Of course I found Graphics32 and Image32, but they seem to be a bit much. And it looks like I need to implement the basic stuff I need (the drawing) by myself. At least I did not find the "old demo of the GR32_Objects unit" you mentioned.

I'm currently looking to integrate softphone functionality into our software. I'm looking for VoIP/SIP SDKs/components. 2 years ago I alreay tried (and even bought) Delphi SIP components but ran into trouble when the other side hanging up did not get registered correctly. I raised the issue with the developer but he soon stopped responding. It was easy to use, but at the same time rather limited. Now I found VoIP SIP SDK - ABTO Software's VoIP SIP SDK and VoIP SDK, SIP SDK for creating audio, video, and IM Apps (portsip.com) and VoIP für Unified Communications | GlobalIPTel and VaxVoIP SIP SDK - Develop SIP Softphone, webphone, video conferencing, audio conferencing, SIP Server, IPPBX, web dialer, SIP Tunneling Server, Call Recording Server, and IP-Telephony services. and SIP SDK for Windows (mizu-voip.com) Has any of you experience with either? Or can anyone recommenend another SDK/component? My first goal is to implement a softphone client with call recording and possibly audio playback. It should also be able to receive/decode DTMF tones. Possibly later I want to implement DIN CLC/TS 50134-9 "Social Alarm Systems"

Thanks, I know Skia and toyed with the demo programs for a bit. Skia sure is capable, but using Skia would mean that I have to implement all the "diagram" stuff like click to place, connecting lines, etc.

Thanks, I did not know that. That looks like it's a bit much... I also don't understand what "FNC" means. Are they "native" VCL or something different? It may or may not come with a whole host of baggage... In the meantime I found the other component again: DELPHI AREA » Simple Graph Component I really need only some basic stuff I can salvage into my own application. Edit: I tried both and neither has the option to insert (background) bitmaps in the demo. I guess that would be easy enough to implement, but if I remember correctly I had another one that offered this option out of the box. But I can't find it anymore... Edit2: Might have been Simple Graph after all. There in the Demo I can set a bitmap as background in one shape and use that as a background for everything else.

We too are using TMS MQTT to connect to a broker to send and receive. It works quite well, but we initially had some trouble with the correct signaling of lost connections. Hi Sergio, does your component support mTLS (mutual TLS)? I'm working on a scenario where we want to use Scaleways IoT Hub, which offer that the clients can authenticate with the broker via mTLS.

I'm trying to use JSONPath via TJSONObject.FindValue in my program. I'm using Delphi 11. I broke it down to the easiest example and I still can't get it to work: { "name": "Chris", "value": 10000 } Path: $.name My Code after stripping away everything else: var myjson:=TJSONObject.ParseJSONValue('{"name": "Chris","value": 10000}'); var myval:=myjson.FindValue('$.name'); ergebnis.Text:=myval.Value; The JSON get's parsed, but the FindValue returns 'nul'. Am I doing something completely wrong?

Thanks, it works now. 🙂 Perhaps it's me being daft, but I cloud not read either from System.JSON.TJSONObject.FindValue - RAD Studio API Documentation (embarcadero.com) or System.JSON.TJSONPathParser - RAD Studio API Documentation (embarcadero.com) that I don't need to address the document root. Or is there some documentation/example I missed?

I'm currently experimenting with Turbopack DosCommand and try to capture the following output for the "ping" command. (ping is just an example I try with) Ping wird ausgeführt für 8.8.8.8 mit 32 Bytes Daten: But the DosCommand doesn't seem to decode the output right: Ping wird ausgef�hrt f�r 8.8.8.8 mit 32 Bytes Daten: I tried to implement the CharDecoding event to decode the output for Unicode function TForm4.DosCommand1CharDecoding(ASender: TObject; ABuf: TStream): string; var pBytes: TBytes; iLength: integer; begin ilength := ABuf.Size; if iLength > 0 then begin SetLength(pBytes, iLength); ABuf.Read(pBytes, iLength); Result := TEncoding.Unicode.GetString(pBytes); end else Result := ''; end; but I only get chineese characters as a result: ਍楐杮眠物⁤畡杳晥梁瑲映犁㠠㠮㠮㠮業⁴㈳䈠瑹獥䐠瑡湥ഺ湁睴牯⁴潶⸸⸸⸸㨸祂整㵳㈳娠楥㵴㐲獭吠䱔ㄽ㔱਍湁睴牯⁴潶⸸⸸⸸㨸祂整㵳㈳娠楥㵴㐲獭呔㵌ㄱവ湁睴牯⁴潶⸸⸸⸸㨸祂整㵳㈳娠楥㵴㈲獭吠䱔ㄽ㔱਍湁睴牯⁴潶⸸⸸⸸㨸祂整㵳㈳娠楥㵴㈲獭吠䱔ㄽ㔱਍਍楐杮匭慴楴瑳歩映犁㠠㠮㠮㠮ഺ †倠歡瑥㩥䜠獥湥敤⁴‽ⰴ䔠灭慦杮湥㴠㐠‬敖汲牯湥㴠〠਍††〨‥敖汲獵⥴ബ慃‮敚瑩湡慧敢湩䴠汩楬敳⹫ഺ †䴠湩浩浵㴠㈠洲ⱳ䴠硡浩浵㴠㈠洴ⱳ䴠瑩整睬牥⁴‽㌲獭਍

Thanks, that worked. The joys of windows legacy and eternal backwards compatibility...

Same as without event handler, which is no surprise, as "TEncoding.ANSI" is the default in the DosCommand Unit. https://github.com/TurboPack/DOSCommand/blob/4ded41648e4e1aafa372c7a740fb2366aeb3e9e4/Source/DosCommand.pas#L1042

GetIt on my Delphi 11 still shows 8.68. Does the release via GetIt take more time, or did I miss some refresh somewhere?

I'm currently designing a REST API for a larger existing Delphi application and I'm currently looking into various options. I don't need a lot of "magic", I actually prefer my code to be straight forward so THttpAppSrv looks great to me. I should be able to implement most of my endpoints in GET and POST-Handlers. But for some PUT and DELETE would make more sense. How would I best implement PUT and DELETE? Should I work around and just use GET and POST for everything? Can I somehow use a "generic" dispatch with THttpAppSrv, handle PUT and DELETE there and use the GET- and POST-mechanism as provided? Or would it be easy to add PUT- and DELETE-Handler "infrastructure" to THttpAppSrv? I tried looking into the code, but I'm not familiar with ICS so it's all greek to me...

After I updated ICS (to 8.68) I added the handlers for PUT and DELETE, but it looks like I never tested them properly. My process produces only "501 Unimplemented". I wanted to try your example OverbyteIcsDDWebService.dproj because there you added the handlers, but I couldn't compile it. I had to add 'OverbyteICSURl' to the Uses of 'OverbyteIcsDDWebServiceSrv' and Answer String in line 2398 misses the code page argument. After fixing that I could compile and start (after editing the .ini) the process. But there it also throws an "501 Unimplemented" for the put handler when calling delete for "restapi.html. In the end I needed to add the options 'hoAllowPut' and 'hoAllowDelete'. After I added them on my project the calls work as well. So I can say it works now, but your example may need some minor tweaks.

Did you have time to check if there is a bug for POST and why GET produces alternately a 401 and 500 on failed authentication?

Checking Client.AuthUserName in .Execute would work for me (if it worked). It would also pave the way for future endpoints with different authorizations per user. I tried it and Client.AuthUserName is always filled, so there might really be a bug as you suspect. But I still wonder why I even get into .Execute after authenticated failed for the "post", while the "get" produces a "401" (and every other time a 500...) before calling the .Execute.

Hm, thanks for the answer, but it get's stranger. I don't have any of the "On*Document" events implemented at all, because all processing happens in my "TLISAAPIRADA.Execute" procedure. I don't serve documents or anything. (I've specified a HttpAppSrv1.DocDir, but that's empty at the moment) The hg401-handling in the examples happens all in the "On*Document" handlers. Now the funny part is: The first unauthenticated "get" gets a 401 response with <HTML> <HEAD> <TITLE>401 Access Denied</TITLE> </HEAD> <BODY> <H1>401 Access Denied</H1>The requested URL /protocol/6192458077624899 requires authorization.<P> </BODY> </HTML> as a body. (other endpoint, same .Execute - refactoring is pending when Auth works...) The next "get" gets a "501 Unimplemented". Then the next the 401 again and then the next the 501. And so fort... Where should I put a check if the client Flags are hg401, I I only use my own TUrlHandler class via "Add*Handler"? I tried adding if Flags=hg410 then exit; to the top of my ".Execute", but the compiler complains that hg401 is undeclared (E2003), despite "OverbyteIcsHttpSrv" being in my uses clause. EDIT: My eyes are getting tired, "hg401" is the correct one. I will try it and get back... EDIT 2: It looks like "flags" is the one belonging to the URL-Handler and not the one for the client. I can't find how to access the client flags. "client.flags" does not work.

Yes, but via plugin. Default seems to be 0.9.1. And I'm not really interested in what RabbitMQ is using, but what this library is using. I'm not familiar with these protocols, but I dug into the code and found the version constants: https://github.com/sonadorje/rabbitmq-delphi/blob/34bcf2e76f04a7be08d701dd82c5d86c0ada0cd7/AMQP.Types.pas#L1046 AMQP_VERSION_STRING = '0.9.1';

I asked if the rabbitmq-delphi project support AMQP 1.0. I had another look at RabbitMQ and it looks like it primarily uses AMQP 0-9-1. I primarily use MQTT with "traditional" MQTT-Brokers, but when I compared Message Queue technologies and brokers/IoT Hubs I noticed some (primarily) support AMQP 1.0, so perhaps if this library supported version 1.0 I could use it (or parts of it) to connect to those. But as RabbitMQ primarily uses AMQP 0.9.1 I think this library also uses this version.

Does this support AMQP 1.0? There are only few comments and some of them are in chinese(?). Do you plan to add some more comments, describe the tests a bit, or give some more examples?

Thanks a lot. I'm going to take a look at the new example code. The examples are always helpful.

Do you have (at least a one way) replication planned for a future release?
