>>>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.

>>With FoxBarcodeQR not need to copy and delete the image file generated.

>>In the Image control's Label, you must call the method QRBarcodeImage() as shown in the image in http://i3.codeplex.com/download?ProjectName=VFPX&DownloadId=625345 or the attachment file.
>>
>>In this way, each image file has a unique name generated and saved in a folder in the Windows temporary files, automatically eliminating in the Destroy event of the QRBarcode class.

FoxBarcode and FoxBarcodeQR are compatible with VFP 6.0 and above.
