  2. Change Source Code

    License the SDK through source code. If you have more than one license, please separate them via ';'

     // C
     DBR_InitLicense(hBarcode, "t0068NQAAAI8+mMcYRNwmijAzExhq******");
     // C++
     CBarcodeReader reader;
     // C#
     BarcodeReader reader = new BarcodeReader();
     reader.ProductKeys = "t0068NQAAAI8+mMcYRNwmijAzExhq******;t0068NQAAAIeI8yyQAGUkz******";
     ' VB.NET
     Dim reader As BarcodeReader = New Dynamsoft.Barcode.BarcodeReader()
     reader.ProductKeys = "t0068NQAAAI8+mMcYRNwmijAzExhq******;t0068NQAAAIeI8yyQAGUkz******"
     // PHP
     $br = new BarcodeReader();
     //iOS SDK:
     BarcodeReader *br;
     br = [[BarcodeReader alloc] initWithLicense:@"t0068NQAAAI8+mMcYRNwmijAzExhq******;t0068NQAAAIeI8yyQAGUkz******"];
     //Android SDK
     BarcodeReader mBarcodeReader;
     mBarcodeReader = new BarcodeReader("t0068NQAAAI8+mMcYRNwmijAzExhq******;t0068NQAAAIeI8yyQAGUkz******");
     //JavaScript SDK
     // In the dynamsoft.barcodereader.js file
     BarcodeReader.licenseKey = 't0068NQAAAI8+mMcYRNwmijAzExhq******;t0068NQAAAIeI8yyQAGUkz******';
