278642 FoxBarcode FAQs

I can read the images generated by FoxBarcode?

Yes, with the following readers online:

Can you rotate bar codes generated

Yes, changing the value of the nRotation property. Valid values are: 0 -> 0°, 1 -> 90°, 2 -> 180° and 3 -> 270°.

Why the error "OLE error code 0x800A0046"?

This is a bug in VFP Image object and images different JPG and BMP formats. A workaround is to write the following code in the Destroy method of the Image object:


Why does the scanner does not read the code generated by FoxBarcode?

If printing is not good, increases the value of the nFactor property to 2 or more.

Also make sure the scanner is correctly configured to read the bar code symbology selected.

The human-readable is not clear

Use the image format PNG or BMP. Setting the property cImageType = "BMP" or "PNG"

FoxBarcode Supports QR Code?

Currently supports the QR Code with the supplement FoxBarcodeQR which uses the free library BarCodeLibrary.DLL of Dario Aranda Alvarez (Mexico)

In the GS1-128 code the parentheses that you say are called Application Identifiers. FoxBarcode has the property that you configure lUseAppId = .T. the parentheses to show only in human-readable. In the bar code includes the FNC1 character as specified by the regulations. See more about GS1-128 in the local site

If you do not have barcode reader look at the following readers online:

I am trying to use EAN/UCC/GS1-128 for the pharmacy industry in Argentina and I have the following concern. GS1 and ANMAT pretend to include in the human readable text some parenthesis (01)007799999(21)000001 and so on. The problem I have is that the parenthesis are included in the codebar and some bar readers read them (not the one I have). So what I need is if it is any way (I am sure there is) not to include the parenthesis in the code bar but they must be human readable. Any help will be much appreciatted!

Alejandro: For standard EAN/UCC-128 does not display the check digit in the human readable text, but is calculated by FoxBarcode and inserted into the barcode.
