Black Box instead of a barcode

I embedded your control in a form and I get a black box instead of a barcode?
Your developing environment selected bad default colors for our control. Simply customize hte control by yourself and set the background color (Backcolor) on white (clWhite). This will solve the problem.

Licensed version can't be compiled by Delphi to an EXE

I have licensed the ActiveBarcode control, but I still can't compile my Delphi project: I get an exception about the License info!?
Please remove the ActiveBarcode control from your development environment and add it again into it after you've licensed the control. Otherwise the development environment may not notice the change of license.

Barcode does not change in the picture property

I use ActiveBarcode with Delphi. 3.0 in a database. First I open a dataset and print the barcode. This works fine. Now I do this again with another dataset and now the same barcode is printed. I'm using the picture property for printing.
Please add the following line of code to your project exactly before you create a new barcode:
 Barcode1.Picture.CleanupInstance;
