How to format data in Crystal Reports

I am having trouble producing the data that I need for PDF417.

stringVar DataToEncode:="[)>~03006~d029X000000~029N{NUM}~029V{Value}~029A1111~029{?Weight}~030~004";
numberVar EcLevel:=0;
numberVar TotalColumns:=0;
numberVar TotalRows:=0;
numberVar Truncated:=0;
numberVar PDFMode:=0;
numberVar ApplyTile:=1;

// - Do not make changes below this line -
stringVar CompleteBarcodeString:="";
numberVar i:=0;

numberVar Segments:= IDAutomationPDF417EncoderPDFSet(DataToEncode, EcLevel, TotalColumns, TotalRows, Truncated, PDFMode, ApplyTile);
For i:=0 to Segments Do
(
CompleteBarcodeString := CompleteBarcodeString + IDAutomationPDF417EncoderPDFGet(i);
);
CompleteBarcodeString



The scanned barcode does not show correctly. How do i fix this issue?

PDF417 and other Barcode Fonts

The + symbol and the & symbol are designed to concatenate data/data fields. A field pulled from a database/data source or a symbol used to concatenate the data (+, &) does not need to use quotes. Inserting a field in quotes, such as "{@Value}" will yield {@Serial}. Your goal is to pull the data from the serial field not display the name of the field in the scanned result.

Here is an example

Say, {field} is a value in my database that equals ABC. When I set the DataToEncode to stringVar DataToEncode:="12345" + {field} + "67890"; the barcode should scan as 12345ABC67890.

If I include my {field} in quotes such as stringVar DataToEncode:="12345 + {field} + 67890"; the generated barcode will scan as 12345{field}67890.

In your example, set up the data as:

stringVar DataToEncode:="[)>~03006~d029X000000~029N" + {NUM}+ "~029V" + {Value}+ "~029A1111~029" + {?Weight} + "~030~004";

All of the character data are within quotes and the fields are not within quotes. The + symbol concatenates all of the data.
