Hi All,

Is there a way to print a QR code from Appeon datawindow?

I have the QR code as blob image in the database. 

If any logic and solutions, please let me know.

Regards/Jinu Nair

Hi.

If the image in blob is of any of types: BMP, GIF, JPEG, RLE, or WMF you may be able to show it using bitmap function in a computed field.

Ok. But have in mind that before using the function you should save the blob to a file. Take a look at PB's help.

Other solutions may be to use an ole control or to use an InkPicture object (this one can show image directly from blob).
