We need to print a 2D Barcode in a label. We are using a 3rd party package (foxbarcodeqr) which takes the string you pass it and creates a JPG (PNG/BMP also available) file. This part is working properly.

The code in my "Print" button is.....

SET STEP ON 
loFbc = NEWOBJECT("FoxBarcodeQR","progs\foxbarcodeqr.prg")
SCAN
**** Set the data for the bar-code field
	lcBarCodeString = TRANSFORM(recv_lbl.recv_qty )
	lcBarCodeString = lcBarCodeString + ";Record "+TRANSFORM(RECNO())
	lcBarCodeString = lcBarCodeString + ";"+TRIM(crsselection.supname)
	lcBarCodeString = lcBarCodeString + ";"+TRIM(recv_lbl.rev)
	lcBarCodeString = lcBarCodeString + ";"+TRIM(recv_lbl.desc1+desc2)
	lcBarCodeString = lcBarCodeString + ";"+TRIM(recv_lbl.date_code)
	lcBarCodeString = lcBarCodeString + ";"+dtoc(date())
	lcBarCodeString = lcBarCodeString + ";"+TRIM(crsselection.uniq_key)
	lcBarCodeString = lcBarCodeString + ";"+TRIM(recv_lbl.pno)

**** Create the bar_code image
	lcQRImage = loFbc.QRBarcodeImage(lcbarcodestring,,2,1)

**** Copy to the "Picture" file
	COPY FILE (lcQRImage) TO ("c:\tempdl\2d_bar_code.jpg")

	DELETE FILE (lcQRImage)

	Label Form [Reports\2d_POQUERY] NEXT 1 To PRINTER NOCONSOLE
			
	DELETE FILE ("c:\tempdl\2d_bar_code.jpg")
ENDSCAN

The Label Form has a Picture/Active X Bound Control which is set to Print Picture From a file. The filename property is set to "c:\tempdl\2d_bar_code.jpg"

The problem is that the same bar code is printing on all the labels. I've stepped through the code and verified that this file gets deleted and re-created as expected. I've manually changed the "bar-code picture" to a real picture image before issuing the next LABEL FORM command, but I still get the original image.

I've tried SYS(1104) in the hope that would clear wherever the picture is being cached, but without success.

All suggestions welcome.
