  1. This is 32Bit client directory for a 64bit installation for FirebirdSQL. It is indeed 32bit application. No mistake here. BTW, if you check the error message in my second post above, it is trying to load a DLL file in another directory (which is EXE directory) and saying file does not exists. Indeed there is no such file with EXE file and I am trying to figure an INI parameter to provide location of that file. If I copy just fbclient.dll file from C:\Program Files\Firebird\Firebird_2_5\WOW64 next to EXE and it works just fine.
  2. This is FirebirdSQL 2.5.9. File I am putting in INI file is FirebirdSQL installation directory. I suppose anything necessary would be present there. Moreover, there is no problem for other applications to use that identical client DLL file. I think this can be eliminated from possible reasons in my specific case.
  3. This is not helping in my case. I get below error which indicates a completely different dll filename First chance exception at $775DA8B2. Exception class EFOpenError with message 'Cannot open file "C:\dlp\MARS\Demos\EKON22\bin\fbclient.dll". The system cannot find the file specified'. Process EKON22ServerApplication.exe (13632) That directory mentioned in above error is the EXE directory itself. My INI file has lines in my initial post. INI file stays in the same directory as EXE and have same filename with EXE. The MARS Engine is started using below lines. My MARS code base is latest available from GitHub. procedure TMainForm.FormCreate(Sender: TObject); begin FEngine := TMARSEngine.Create(); try FEngine.Parameters.LoadFromIniFile; FEngine.AddApplication('DefaultApp', '/default', ['Server.*']); PortNumberEdit.Text := IntToStr(FEngine.Port); TMARSFireDAC.LoadConnectionDefs(FEngine.Parameters, 'FireDAC'); StartServerAction.Execute; RenderEngines(MainTreeView); except FreeAndNil(FEngine); raise; end; end; If I am missing something, let me know, please.
  4. Hello, I am trying to provide client library for FirebirdSQL database connection for a MARS-Server project. I tried a few different INI parameters, all failed including second line below FireDAC.MAIN_DB.DriverID=FB FireDAC.MAIN_DB.VendorLib="C:\Program Files\Firebird\Firebird_2_5\WOW64\fbclient.dll" FireDAC.MAIN_DB.Database=C:\Program Files\Firebird\Firebird_2_5\examples\empbuild\EMPLOYEE.FDB I wonder what I should be using to be able to use a fbclient.dll in another directory than the EXE file. Thanks & Regards, Ertan

    Internet time sync - with some timeout

    Thank you to all. My request to have access to problematic computer will not be possible until March 15 due to Covid-19 close down. I will be able to do further analysis after I do have access.

    Internet time sync - with some timeout

    I just read it. Thanks for sharing. It seems similar. But, in this thread, code continues and not hangs like in my case. If I had same problem, thread would terminate without clock being synced. My problem is thread not terminating. One additional information I should share is that procedure is threaded using ITask like below. uses System.Threading, uUtils.Log; procedure TForm2.FormCreate(Sender: TObject); var Task: ITask; begin Log('Creating thread'); Task := TTask.Create(SetSystemTime); Task.Start(); Log('Thread started'); end; procedure TForm2.IdSNTP1Connected(Sender: TObject); begin Log('SNTP Connected'); end; procedure TForm2.IdSNTP1Disconnected(Sender: TObject); begin Log('SNTP Disconnected'); end; procedure TForm2.IdSNTP1Status(ASender: TObject; const AStatus: TIdStatus; const AStatusText: string); begin Log('SNTP status: ' + AStatusText); end; procedure TForm2.SetSystemTime(); var Sntp: TIdSNTP; begin Log('SetSystemTime(): System clock sync starting'); Sntp := TIdSNTP.Create(nil); try Sntp.OnConnected := IdSNTP1Connected; Sntp.OnDisconnected := IdSNTP1Disconnected; Sntp.OnStatus := IdSNTP1Status; Sntp.Host := 'pool.ntp.org'; Sntp.ReceiveTimeout := 2000; try Log('SetSystemTime(): Running actual time sync...'); Sntp.SyncTime(); Log('SetSystemTime(): System clock sync completed'); except on E: Exception do begin Log('SetSystemTime(): ' + E.Message); end; end; finally Sntp.Free(); end; Log('SetSystemTime(): Done'); end; That code sample is from a project that I am preparing with detailed logging to help identifying the problem. That code running on my system produces with following lines: 2021-01-20 14:56:58.949 Creating thread 2021-01-20 14:56:58.952 Thread started 2021-01-20 14:56:58.953 SetSystemTime(): System clock sync starting 2021-01-20 14:56:58.953 SetSystemTime(): Running actual time sync... 2021-01-20 14:56:59.067 SetSystemTime(): System clock sync completed 2021-01-20 14:56:59.068 SetSystemTime(): Done As you can see, there is no connection or disconnection here. Problem might be privilege but, this should not hang whole thread and should just exit from it. BTW, I just learned (by chance talking to a colleague) that problem occurs only on Windows 10 OSes and not on Windows 7 or Windows XP.

    Internet time sync - with some timeout

    I forgot to mention in my initial post that I have already tried to change ReceiveTimeout to 2000 with no success. Sorry about that. Since ReceiveTimeout did not work that makes me believe there is a kind of a problem like privilege or initial connection. I do not know though. I cannot access to computers in that location for better understanding.
  8. Hello, I have following code running in a thread when application starts. procedure TMainForm.SetSystemTime(); var Sntp: TIdSNTP; begin Sntp := TIdSNTP.Create(nil); try Sntp.Host := 'pool.ntp.org'; try Sntp.SyncTime(); except // eat exception, we are in thread end; finally Sntp.Free(); end; end; When there is no internet connection, thread above code runs is never terminated. I could not find some connection timeout setting for IdSNTP. Is there any other way to terminate Sntp.SyncTime() if it is not completed for a certain period of time like 10 seconds. There is a location with a corporate firewall (with some weird settings I believe) where check for an internet connection is true, but above code still hangs. Thanks & Regards, Ertan

    Deploying certificate with your Android app

    I did add private key certificate as a resource as I tried to explain in my initial post. I did deploy my security config "network_security_config.xml" under "res\xml" in project Deployment. Sorry, forgot to mention that in detail. BTW, I am not trying to deploy my app in Play Store. Just trying to deploy it with my self signed HTTPS certificate.
  10. Hello, I have my HTTPS proxy for my HTTP REST server. Both running on my development computer. I setup HTTPS proxy following instructions here: https://twigstechtips.blogspot.com/2016/01/nginx-how-to-set-up-ssl-reverse-proxy.html These instructions makes you generate two certificate files. KEY and PEM files. I added that PEM file in my project resources as resource type RCDATA and used identifier "my_ca". I used below link to prepare my security config xml https://stackoverflow.com/questions/56301765/self-signed-certificate-in-android-application-of-rad Using "@raw/my_ca" as in that stackoverflow question is failing with below error (while packaging the app) when I try to debug run the app. network_security_config.xml:6: error: Error: No resource found that matches the given name (at 'src' with value '@raw/my_ca/') So, I prepared my XML file as following: <?xml version="1.0" encoding="utf-8"?> <network-security-config> <domain-config> <domain includeSubdomains="true">yourdomain.com</domain> <trust-anchors> <certificates src="my_ca"/> </trust-anchors> </domain-config> </network-security-config> When I try to access my REST server like https://192.168.1.152/... I get following error Failed to parse XML configuration from network_security_config On the other hand, I can get results just fine using identical URL and Postman on Windows OS. I simply failed to figure how to add that self signed certificate in my app package and use it. Any help is appreciated. Thanks & Regards, Ertan

    How to extend CE licence?

    I did not do that. This is what I suspect reading e-mails sent from Embarcadero.

    How to extend CE licence?

    Assuming you are actually using CE version mainly. You are excited about new 10.4 features and wanted to see them at first hand. So, you installed it on your computer for trial. You uninstalled 10.4 from your computer before the end of trial period (or after, or keeping it without using). At that point, I suspect, Embarcadero puts you (your e-mail address and relevant account linked to your CE license) in "not eligible for CE anymore" list. Hence the e-mail messages received. I wonder if that theory is correct for people having problems updating their CE licenses.
  13. Hello, I am using Delphi 10.3.3 and trying to consume a SOAP web service method. Wsdl that I need to use is below: https://dev.gittigidiyor.com:8443/listingapi/ws/IndividualSaleService?wsdl Delphi 10.3.3 successfully imports that wsdl page. Imported unit generates an output XML for "getPagedSales" method as following (included only relevant parts of XML): <?xml version="1.0"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"> <SOAP-ENV:Body> <getPagedSales xmlns="http://sale.individual.ws.listingapi.gg.com"> When same wsdl is imported using SOAP-UI application, generated sample request output starting as following: <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sale="http://sale.individual.ws.listingapi.gg.com"> <soapenv:Header/> <soapenv:Body> <sale:getPagedSales> If you look closely and compare both, the SOAP-UI generated XML, envelope has "sale" in it as well as method name is put after "sale". My problem is that web service is not accepting Delphi request and returning an error as following: <env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'> <env:Header/> <env:Body> <env:Fault xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'> <faultcode>env:Client</faultcode> <faultstring>Endpoint {http://application.anonymous.ws.listingapi.gg.com}ApplicationServicePort does not contain operation meta data for: {http://sale.individual.ws.listingapi.gg.com}getPagedSales</faultstring> </env:Fault> </env:Body> </env:Envelope> My question is: Is it possible to modify wsdl imported unit in a way so that out of the box SOAP adds that "sale" in relevant places of requests not just for getPagedSale mothod, but for all sale service methods? I know it is possible to use THTTPRIO.OnBeforeExecute() and send identical XML to that of SOAP-UI generated (which web service will be accepting). However, I am just trying to avoid that if it is possible. Thanks & Regards, Ertan
  14. I hope @Ugochukwu Mmaduekwe can make some comments about PKCS7 padding here. I have all below repositories and do not have problem with compilation etc. HlpIhash is part of HashLib4Pascal https://github.com/Xor-el/CryptoLib4Pascal https://github.com/Xor-el/HashLib4Pascal https://github.com/Xor-el/SimpleBaseLib4Pascal
  15. While trying to prepare minimal reproduction I realize that there is an "else" exists above some explanatory remark lines and my Request variable assignment comes next. Turned out my mistake of leaving an else that should have been deleted at the first place. if TokenExpireTime <> 0 then begin // some other stuff with begin..end blocks end else // problem source line // some remark // another remark // more remark Request := '{"appKey":"' + AppKey + '","secretKey":"' + SecretKey + '"}'; It turned out that Request is conditionally filled in if no line above. Sorry about all the fuss and thanks to all.
