Hello Can somebody see what is error in here... I imported WSDL file, trying to upload 2 files,one TXT and PDF, TXT is previously signed... I encode them in base64 and translate to TByteDynArray ,but server doesn't accept them... ------------------------------------- WSDL function function uploadSKZZRacun(const parameters: UploadSKZZRacunRequest): UploadResponse; stdcall; ------------------------------ UploadSKZZRacunRequest = class(TRemotable) ... published property pdf: Datoteka read Fpdf write Fpdf; property unl: Datoteka read Funl write Funl; ---------------------------------- Datoteka = class(TRemotable) private Fnaziv: string; Fdatoteka: TByteDynArray; published property naziv: string read Fnaziv write Fnaziv; property datoteka: TByteDynArray read Fdatoteka write Fdatoteka; end; -------------------------- UploadResponse = (SUCCESS); ---------------------- var zahtjev:UploadSKZZRacunRequest; rezultat:UploadResponse; buffer:String; binaryData: TByteDynArray; begin zahtjev := UploadSKZZRacunRequest.create; dat_unl := datoteka.create; dat_unl.name := ExtractFileName(filenameedit1.text);// '034_Rn_9308930850005.Z25.p7s'; buffer := EncodeFileToBase64(dat_unl.name ); SetLength(binaryData, Length(buffer) * sizeof(Char)); if Length(buffer) > 0 then Move(buffer[1], binaryData[0], Length(buffer) * sizeof(Char)); dat_unl.datoteka := binaryData; rezultat := (HTTPRIO1 as CezihWs).uploadSKZZRacun(zahtjev); zahtjev.free;

thanks on your help, seems that this was error, server said it was encrypted so it couldnt verify signature

hi, does anybody uses securebridge from DEVART to sign a pdf, i dont know is it good code: var signed, bajtovi: TBytes; fajl:tfile; ScMemoryStorage1.ImportFromPKCS12('c:\_Projekti\028.pfx', 'Pero412'); bajtovi := fajl.readallbytes('c:\_Projekti\Svjedodzba.PDF'); signed:= ScMemoryStorage1.Certificates.Certificates[0].Sign(bajtovi,haSHA1,pmPKCS1); SaveBytesToFile(bajtovi,'c:\_Projekti\Svjedodzba_signed.PDF');

hello is it possible to have 2 or more version of the same dll in application? (ssleay32.dll and libeay32.dll) i have some old unit whitch uses openssl dlls from 2005 and i am sending emails with Indy which required openssl dlls from 2019... i have set a path for Indy dlls at the program start, initialisation, sslpath... when i use loadlibrary('') for this 2005. year dll, i cannot send emails enymore with indy, it say "the ordinal 3844 could not be located in the dynamic link library"

i think this will not work... But why application cant free dll previously loaded with Handle := LoadLibrary(pchar(ExtractFilePath(Application.ExeName)+ 'ssl_old\DLL-2005\libeay32.dll')); with freelybrary FreeLibrary(Handle); Handle := 0;

hello,i am not familiar with ssl much.. I have some old delphi code for sending soap messages ,it uses oopenssl: "Delphi import unit for OpenSSL libeay, version 0.7m, 2010-11-05" it works only with dlls from 2005 year (ssleay32.dll and libeay32.dll) why this EXE dont work with some newer dlls, from 2019 for example...

where can i find needed delphi units for this new openssl ? (libeay32.pas,libexslt.pas,libxml2.pas,libxmlsec.pas...)

Hello I have question about indy,sending and receiving messages from-to ECR-POS(Ingenico), am i doing it right ? ------send to POS request for Card paying IdTCPClient1.IOHandler.InputBuffer.Clear; IdTCPClient1.IOHandler.Write(buff); Timer4.Enabled := true; ---------on timer4 try if IdTCPClient1.IOHandler.InputBufferIsEmpty then begin if IdTCPClient1.IOHandler.CheckForDataOnSource(1000) then begin bajt := IdTCPClient1.IOHandler.ReadByte; bajt := IdTCPClient1.IOHandler.ReadByte; IdTCPClient1.IOHandler.ReadBytes(Buffer,bajt - 1,true); s := ''; for i := 0 to bajt - 1 do s := s + chr(buffer); Memo1.Lines.Add(s); Timer4.Enabled := false; end else IdTCPClient1.IOHandler.InputBuffer.Clear end else IdTCPClient1.IOHandler.InputBuffer.Clear; except end;

thanks a lot for you answers

compiler says error,no such function this code works... ------------------- bajt := data1.IdTCPClient1.IOHandler.ReadByte; bajt1 := data1.IdTCPClient1.IOHandler.ReadByte; bajt2 := bajt * $10 + bajt1; data1.IdTCPClient1.IOHandler.ReadBytes(Buffer,bajt2,false); s := ''; for i := 0 to bajt2 - 1 do s := s + inttohex(buffer,2); ---------------------------- i need a hex, I explode it with 1C delimeter, its easy to handle.. What AApend parameter means, true or false, what to use in: data1.IdTCPClient1.IOHandler.ReadBytes(Buffer,bajt2,false); ?

thanks Datagram protocol Datagram protocol is used over stream-oriented protocols (TCP) to provide information to the receiver of the length of the data being sent. Datagram protocol forms a packet by adding a header to the payload. Datagram protocol header contains the length of the payload encoded in two bytes. Header Format Header consists of two bytes with the most significant byte first: Byte Value 1 Message length/256 2 Message lengt%256 --------------------------------------- Length of data Header Packet 7 0x00 0x07 0x00 0x07 B1 B2 B3 … B7 17 0x00 0x11 0x00 0x11 B1 B2 B3 … B17 135 0x00 0x87 0x00 0x87 B1 B2 B3 … B135 i need timer (put on 2000 ms), becouse i wait for customer to insert credit card on POS terminal, then POS will sent some message to me,starting with 10xxxxxxx first 2 bytes is size of packet,i think first one is always zero ? thanks,i will try it

Does anybody have experience with 2d barcode, TurboPower SysTools, component StPDF417Barcode... I can't add StPDF417Barcode1.code = '...' witch contains some local letters (ŠĐČĆŽš), it says "Range check error"... virm_grad ,virm_adresa ,virm_naziv:string; virm_naziv := utf8encode('dsdddddd'); virm_adresa := utf8encode('ŠĐŠĐČĆĆČĆČ'); virm_grad := utf8encode('špšpUIZUZUZ'); StPDF417Barcode1.Code := 'HRVHUB30' + #13#10 + 'EUR' + #13#10 + virm_naziv + #10 + virm_adresa + #10 + virm_grad + #10;

Thanks Brian, by putting Datamode to binary solved the problem

hi i need to send some HEX to POS terminal, amount of money, and POS will then check if credit card if valid and send me some answers..like this: (<STX><STX>message<ETX><LRC>) ECR-->POS: <STX><STX>303030303030303030303031303030<FS>31303030<FS><FS>2B30<FS>313931<FS><FS><FS><FS><FS><FS><FS><FS><FS><FS><FS>3030<FS>31<FF><FS><FS><FS><FS><FS><FS><FS><FS><ETX>2C POS-->ECR: <ACK> POS-->ECR: <STX>32303030303030305542414349204B415254494355<ETX>2E ECR-->POS: <ACK> ------------------------------------------------------------------- I try with Indy IdTCPClient1 but I dont receive nothing from POS. Am i sending wrong code or I dont know how to receive answer ? They say i need do send HEX string.. So i translate this HEX: <STX><STX>303030303030303030303031303030<FS>31303030<FS><FS>2B30<FS>313931<FS><FS><FS><FS><FS><FS><FS><FS><FS><FS><FS>3030<FS>31<FF><FS><FS><FS><FS><FS><FS><FS><FS><ETX>2C to 02023030303030303030303030313030301C313030301C1C2B301C3139311C1C1C1C1C1C1C1C1C1C1C30301C310C1C1C1C1C1C1C1C1C032C and send it like IdTCPClient1.IOHandler.WriteLn(edit7.Text, IndyTextEncoding_OSDefault); timer1.Enabled := true; This is how i wait for server ansver: procedure TForm1.Timer1Timer(Sender: TObject); var receivedtext:string; begin with IdTCPClient1 do begin try if IOHandler.InputBufferIsEmpty then begin IOHandler.CheckForDataOnSource(0); IOHandler.CheckForDisconnect; if IOHandler.InputBufferIsEmpty then Exit; end; receivedtext := IOHandler.ReadLn; except Timer1.Enabled := False; Exit; end; if receivedtext <> '' then ShowMessage(receivedtext); end; end;

all thanks goes to Remy

i can't figure out how to parse json answer from some invoice company I use Delphi XE4, DBXJSON... How to get Jsonpairs insde nested objects... Example: { "messageAck": { "messageID": "Middleware_002", "messageAckID": "8f50dd66-a77f-45ec-9049-0faadb69ff43", "messageType": 9002, "ackStatus": "ACCEPTED", "ackStatusCode": 10, "ackStatusText": "Poruka zaprimljena!" }, "b2GOutgoingInvoiceEnvelope": { "b2GOutgoingInvoiceProcessing": { "correctB2GOutgoingInvoice": {"supplierInvoiceID": "dokument1","invoiceID": 84001,"invoiceTimestamp": "03-03-2020"}, "incorrectB2GOutgoingInvoice": null}} }

you are right, thanks for you help and your time

this works ok.. var jasonArr:TJSONArray; par: TJSONPair; i: Integer; LItem:TJSONValue; JsonValueArr : TJSONValue; testValue: TJSONValue; begin jasonArr := GetValue(JsonObject, 'documentStatus') as TJSONArray; for JsonValueArr in jasonArr do begin for LItem in TJSONArray(JsonValueArr) do begin if TJSONPair(LItem).JsonString.Value = 'statusCode' then odgovorFinaStatus.b2gStatus := TJSONPair(LItem).JsonValue.Value else if TJSONPair(LItem).JsonString.Value = 'statusText' then odgovorFinaStatus.b2gStatusTekst := TJSONPair(LItem).JsonValue.Value else if TJSONPair(LItem).JsonString.Value = 'statusTimestamp' then odgovorFinaStatus.b2gStatusVrijeme := TJSONPair(LItem).JsonValue.Value else if TJSONPair(LItem).JsonString.Value = 'note' then odgovorFinaStatus.b2gStatusNapomena := TJSONPair(LItem).JsonValue.Value else if TJSONPair(LItem).JsonString.Value = 'partialAmount' then begin try odgovorFinaStatus.b2gDjelIzn := StrToFloat(TJSONPair(LItem).JsonValue.Value); except odgovorFinaStatus.b2gDjelIzn := 0 end; end;

when i write for LItem in TJSONObject(JsonValueArr) do it says: [dcc32 Error] Unit1.pas(568): E2010 Incompatible types: 'TJSONValue' and 'TJSONPair'

something like this, seems to work: jasonArr := GetValue(JsonObject, 'documentStatus') as TJSONArray; for JsonValueArr in jasonArr do begin for LItem in TJSONArray(JsonValueArr) do begin ShowMessage(TJSONPair(LItem).JsonString.Value + '/' + TJSONPair(LItem).JsonValue.Value); end; end;

it works fine,thanks but now i have some array inside object how to acces this documentStatus element ? { "messageAck": { "messageID": "Middleware_002", "messageAckID": "a98d281b-9608-4b25-be03-7be0403916dd", "messageType": 9012, "ackStatus": "ACCEPTED", "ackStatusCode": 10, "ackStatusText": "Message received!" }, "b2GOutgoingInvoiceStatus": { "supplierID": "9934:86167814130", "additionalSupplierID": null, "invoiceID": 83703, "supplierInvoiceID": "IR-19-1766-1-1", "invoiceTimestamp": "28-02-2020", "documentStatus": [ { "statusCode": "RECEIVED", "statusText": "Received", "statusTimestamp": "28-02-2020", "note": null, "partialAmount": null} ] } }

uh, it's very complicated.. Thank a lot on your effort
