Call Encode Function with Delphi (IDAutomationQRCODE.dll)

Good day,
I'm trying to use QR-Font and Encoder to generate a QR Code in Delphi.
But I'm not sure of the correct syntax.

By referring to the example in VB, I try to modify it to Delphi format to call the EncQR in IDAutomationQRCODE.DLL.

function EncQR(DataToEncode: AnsiString; ProcTilde: Integer; EncMode: Integer; Version: Integer; ErrorCorrectionLevel: Integer): AnsiString;
stdcall;external 'c: IDAutomationQRCODE.dll';

During the compiling, I receive an error "The procedure entry point EncQR not be located in dynamic library".
Can you give me some advice? what is the proper way to work within Delphi?

Thank you very much.

Regards,

Operating System: Windows 7

Application: Delphi XE3

Brov84	Best Answer I solve the problem. I imported the Type Library(installed with the package of IDAutomation on the pc) with Delphi with the wizard, and then you can create a Package Library. After that use the code below: procedure TfMain.btnConvertiClick(Sender: TObject); var qrCode: TQRCode; begin qrCode := TQRCode.Create(Self); sData := 'http://www.test.it/prodotti/tattoo-e-trasferibili/'; iTilde := 1; iEncodeMode := 0; iVersion := 0; iErrConLev := 2; qrCode.FontEncode(sData,iTilde,iEncodeMode,iVersion,iErrConLev,sReturn); txtRisultatoCodifica.Lines.Text := sReturn; end; Posted 11.1 year(s) ago (0) (0) Report Abuse

Unfortunately, IDAutomation cannot support our components within Delphi. However, we can present information that may help guide you to a possible solution.

Though I am not sure if this is completely related the error message might have a solution on Microsoft's knowledge base.
