Why don't you use what I proposed? You will always get an 8 characters key and make use only Delphi RTL functions. Please comment on this. I proposed you use CRC32 which is a kind of hash. https://docwiki.embarcadero.com/Libraries/Sydney/en/System.ZLib.crc32 IntToHex: https://docwiki.embarcadero.com/Libraries/Sydney/en/System.SysUtils.IntToHex

One possibility is to use a CRC32 applied to the text and then convert the resulting UInt32 to hex-ascii representation. See CRC32: https://docwiki.embarcadero.com/Libraries/Sydney/en/System.ZLib.crc32 IntToHex: https://docwiki.embarcadero.com/Libraries/Sydney/en/System.SysUtils.IntToHex

That is a very different thing. The rule: correctly define what your problem is and you'll get the best answers.

There is nothing very special to the "cloud". The cloud is just a bunch of computer in a remote data center. Those computers are running an operating system, some of which are Windows and are able to run a VCL Delphi application. One solution is to use a virtual desktop solution. For example this : https://learn.microsoft.com/en-us/azure/virtual-desktop/overview

Delphi is not even supported on Windows 2008. https://docwiki.embarcadero.com/RADStudio/Athens/en/Installation_Notes#Operating_System_Requirements

Have a look at the demo program OverbyteIcsSslWebServ.dproj! In OverbyuteIcsSslWebServ1.pas, look at method SslHttpServer1PostDocument(). If the posted URL is the one you expect (In the demo, this URL is '/cgi-bin/cgifrm1.exe' and no, there NO cgifrm1.exe program, this is just a kind of virtual program), you have to allocate space for the posted data and return with Flags set to hgAcceptData. Then since you accept data, you'll get one or more PostedData events (Data comes in chunks). In the demo, look at SslHttpServer1PostedData(). In my opinion, this demo is exactly what you want to do. Study it carefully. BTW: If you don't do what I said (Edit you message to translate it in English, even in bad English. Use Google translate if needed), then you delay the answer. Now, study the sample I pointed to you, revise your code and if you still have an issue, post a NEW question, in English.

Please translate your post to English (Use the Edit button).

It is a problem for application which make use of a state machine, something I use frequently. Having an event triggered twice add useless complexity at the application level and leads to bugs, especially for "final" event like OnRequestDone. It is better to handle that in the component.

Please stay on subject. This forum is for ICS only. If you have question about ICS, you are welcome here. For IIS and other subjects please use one of the many other forums on this server. One more note: you are deviating significantly from the original topic of this discussion. Please create a new discussion for each topic. Here we have a forum and not a chat.

I don't need DataSnap: I have ICS which does it all.

I never had any issue with what you call garbage. I'm afraid that the problems you are experiencing actually come from your "manual" manipulation of the dproj. The whole dproj file is not big. This count for nothing in disk space.

That makes no difference. A datamodule is just a kind of form without UI at runtime. It's just an easy way to use the object inspector to assign properties and events to the non-visual components and keep thing in various units.

That's a good idea Angus. Restore also the sample application (OverbyteIcsDllTst1) loading the DLL.

For a DLL, I recommend to put the message pump in a separate thread along will all code related to ICS events. Why? Because you have no control on what the application loading the DLL is doing with Windows messaging and because you don't know how that application calls the DLL's function (could be the main thread or a worker thread). In ICS V8, there was a sample program showing that. It has been removed from V9 😢 You still access it in this place : http://svn.overbyte.be/svn/ics/trunk/Samples/Delphi/OtherDemos The project is OverbyteIcsDll1.dpr. This project needs probably some minor changes to be compiled with V9.

What i said can be done with the IDE. You know I'm using Delphi since the first version in 1995, maybe before your own birth. No, you don't need to edit the dproj file. If you do, you will likely mess it. I'm sure. Please leave this conversation and restart a new one in the appropriate forum. Try to better describe your problem there.
