If there are not any wrapper for Pascal ,you need to arm yourself with a lot of patience and start creating your wrappers from the definitions of the include (i.e. the files with the extension ".h"). It might not be an easy path, quite the opposite. However, there are some tools that can help you: https://github.com/neslib/Chet this utility allows you to create pascal wrappers from .h files. Keep in mind that what is done will not be perfect and you will have to get your hands on it. Also keep in mind that you can only use C includes, NOT C++. And you will also have to convert the code by hand. Another equally valid alternative is to pass the include file and ask some AI to convert it to Pascal ... Surely some forum user will be able to give you some further and better advice. This is an example of conversion of the Indigo APIs performed by the tool I proposed to you, you need to get your hands on it but it is a start. I wish you good work. Indigo.pas Indigo.h

Guidance on FreeAndNil for Delphi noob
DelphiUdIT replied to Paul Dardeau's topic in RTL and Delphi Object Pascal
Nothing ..... wrong replay -
Is not an issue, is the normal function of energy saving, like implemented in "balanced power" profile of a laptop PC. You have disable some of the "mechanism" that allow the system to moderate the use of the battery when the laptop is in battery mode, only for BDS.EXE application. If you prefer performance to energy saving is one of the right approach.

EXE(.exe) still appears in process list, though the service destroyed.
DelphiUdIT replied to sp0987's topic in General Help
I don't know where you catch those info. Like I told, my experience, I nevere see an executable (service or not service) stay live after "termination". In my developer machine runs only basic services, and i start and stop programmatically the services that I need project based (normally 4/5 services for 4 times per days). May be is a "design basis" by Windows for some kinds of executables or (more likely) some thread or method of the executable is "hanging". 20 seconds is historically the standard timeout within which a closing service is killed by the system, if it does not terminate itself (I remember a value like "KillServiceTimeout" in the registry that keeps the default time, but it could be called something different). -

DelphiUdIT replied to sp0987's topic in General Help
@sp0987 And, what are your needs ? If the service maintain the zombies for some seconds ... it is so, but really I never see this. When I stop a service the EXE disappear from task manager (of course, if the application has no pending things like threads waiting). If you want that the same exe doesn't run more then one time, use a mutex at the start of the application: var hMutex: THandle; // Creates a unique synchronized object in the operating system hMutex:=CreateMutex(Nil,False,'Global\MyApplication'); // Checks that the object is not already 'owned' by some other process (program instance), // in which case exits the program if (WaitForSingleObject(hMutex,0) = wait_TimeOut) then exitprocess(255); -

Default() and subrange types
DelphiUdIT replied to Der schöne Günther's topic in RTL and Delphi Object Pascal
For each data whose value I need to know for sure before using it, I perform an assignment operation of a certain value at the creation of any "parent" or at the creation of the application. I had some problems with the "default" in the past, so I equipped myself and I do it like this. I know it's probably excessive, but so far I haven't had any issues. -

Documentation links on indyproject.org not working
DelphiUdIT replied to alan finiti's topic in Indy
Yes, that link is working, when you unzip it with Windows Explorer it gives an error. With 7-ZIP it works right. Other links from Indy Wiki are not fully functional. -

REST Datasnap Server Accepting ECDH Ciphers
DelphiUdIT replied to MikeMon's topic in Network, Cloud and Web
This is available on OpenSSL 1.0.2u, the last SSL available that works on Indy bundle with Rad Studio. You are using SSLv3 this is deprecated and should not be used. YOU MUST USE TLSv1.2. Set IOHandler to use TLSv1.2 (in the options): SSLVersion := [sslvTLSv1_2] -
REST Datasnap Server Accepting ECDH Ciphers
DelphiUdIT replied to MikeMon's topic in Network, Cloud and Web
In Indy, the valid chipers type accepted by a server connection is setting through the TIdSSLOpenIOHnadlerServer.Options.ChiperList property, for example: //For TLSv1.2 handshake CipherList := '!EXPORT:!LOW:!aNULL:!eNULL:!RC4:!ADK:!3DES:!DES:!MD5:!PSK:!SRP:!CAMELLIA'+ ':ECDHE-RSA-AES128-GCM-SHA256'+ ':ECDHE-RSA-AES256-GCM-SHA384'+ ':ECDHE-RSA-CHACHA20-POLY1305'+ ':ECDHE-ARIA256-GCM-SHA384'+ ':ECDHE-ARIA128-GCM-SHA256'+ //Weak but used in old products ':ECDHE-RSA-AES256-SHA384'; Search in the property of DataSnap components for IOSSLHandler and set this property. This is correlated to "certifcate file" and "certificate private key" (CertFIle and CertKey property of the Handler). -
Does anyone know a delphi component that can play videos from a stream
DelphiUdIT replied to ToddFrankson's topic in VCL
You can try also with https://prog.olsztyn.pl/paslibvlc/ It has the ability to play stream audio and video, but you need VLC installed on system. -
But not this time .... Datasnap is working with Indy REPO too .... there are some things to do, expecially one ... was missing from my (sparse) instructions and I never had any issue (never used DataSnap). These three lines must also be copied into the "library path" and DataSnap will "start" working again. Start from previous link posted.

I think was better to create a new topic under "Indy" section. Your issue has nothng to do with this topic. But, if you install new Indy from official repo, you have to build it with all the modifications about the packages and you must rebuild also the optional components, wich sources are distribuited with Rad Studio and not present in Indy REPO. Read this for more information: Take care that replace the Indy bundle with Indy REPO can invalidate some components (from Embarcadero and from third parties). If you have third parties sources you can recompile and rebuild them. EMS components and Datasnap use Indy under the hood ans so is possible that they don't work with new version of Indy.

Uses clauses and ide performance - does it make a difference?
DelphiUdIT replied to ventiseis's topic in RTL and Delphi Object Pascal
But they produce SSD too, and the test that they made were about their SSD. I don't think they have any interest in "cheating" on the results. It could be that technology will move the "hand" one way or the other over time. -

How do I close a modal form without ModalResult being set to mrCancel ?
DelphiUdIT replied to dormky's topic in VCL
Be careful when interpreting "objects", whether they are properties, variables, or other. Granted that as you say there is only one assignment, you do not know what an assignment can trigger. And the same encapsulation paradigm makes sure that the true nature of the property is hidden from you (it can be a reading of a variable, a writing, a function or triggering a series of delayed and events). Try to think what "triggers" a simple assignment of a property such as a connection to a DB (...Connected := True;). It is necessary to document yourself, in the absence of experience. This must always happen when dealing with a new topic. -
Don't worry, when you feel the need just ask. Someone will help you. You'll find that Delphi (Pascal) will help you on the way. Also try to have a quick read about the various topics in the various manuals available, there are several available even for free. You can also do a search on the forum and you will find several links about this. Embarcadero's online wiki can also help you. Enjoy and good works.

DelphiUdIT replied to dormky's topic in VCL
Look at this: https://docwiki.embarcadero.com/Libraries/Athens/en/Vcl.Forms.TCustomForm.ModalResult Like @Lajos Juhász said, if you set the ModalResult at value different from mrNone the Form will close when the actual procedure will exit;
