Hello Dylan,   It's a shot in the dark with this little information, but widgets might show up black in the application when they are missing in your .ini files.   Dennis.

Hello Dennis, Thank you for your answer Unfortunately I don't have other information, apart that, this problem occurs on Windows 7 and not on Windows xp .. how to check the ini file?

Hi Dylan, supposing you have your barcode font named "3 of 9 Barcode" you should first map your font into the [screen] and/or [printer] section of your ini file...something like: myBarcodeBig=3 of 9 Barcode,50,regular myBarcodeMedium=3 of 9 Barcode,36,regular myBarcodeSmall=3 of 9 Barcode,24,regular myBarcodeSmallest=3 of 9 Barcode,16,regular then refer to the suitable name defined in properties of your field picted on the form/report. If you use them a lot you should also consider to model a special set of widgets into your .ini file. Ciao, Gianni
