When you print bar codes in the report, sometimes you found shot garbled, even if the standard system!
When setting up a print bar codes, corresponding StringEdit has two properties Note: Font and DataMethod, beginning with the BC bar code font is, if the Font setting: "BC C128 HD Wide" DataMethod you will need to set the corresponding "BarcodeEAN128 . "
BarCode can learn how to use reference Report: AssertBarcode
in determining the BarCode font we want to use, you can use the following code directly BarCode:
BarcodeCode39 barcode;
;
barcode = Barcode::construct(BarcodeType::Code39);
//is it needed to validate this barcode before print?
barcode.clear();
barcode.string(true,strltrim(strrtrim(num2str(this.OprNum,10,0,1,0))));
return barcode.barcodeStr();BarCode system is that all the parent class barcode, there are many different sub-classes below it, as long as we declare a corresponding class, and for using ENUM value returned construct corresponding configuration instance, we have to then pass into the barcode string to this example, read a bar code on it.
Sometimes garbled, I found that everything is correct when checking code and attributes. This problem arises because there are several possibilities:
- Font type required does not exist in the client or server side
2. The client operating system and server operating systems, resulting in different character sets
Solution:
First, ensure that the client and server have this font, then change the call RunOn property MenuItem report is "Called from" (change the operating system is clearly unrealistic!).
