Miscellaneous Barcode-ActiveX FAQ |
What image formats can barcode be saved in?
Can your barcode controls be used in scripting languages (VB Script, Java Script)?
Are your controls compatible with .NET, and how should they be used in the .NET environment?
Do any of your products allow encoding a NULL (hex 00) byte?
I have installed a demo version of the software. Works exactly as we would like. What is involved in Licensing this product so that my current demo will display without the Demo label?
What are the limitations to the demo version of BarCode-ActiveX? I tried creating a Code 39 barcode and it only produced a criss cross pattern of a box, is this right?

All our barcode controls can save files in the following formats: JPEG, GIF, PNG, TIFF, BMP, WMF, EMF.
To be able to save images in these formats, you must have the GDI+ library (supplied beginning from
Windows XP, 2003 and higher) on your PC. If you do not have this library, you can copy it to the
System32 folder from any other PC where it is installed.

Yes, you can use our barcode controls in such scripting languages as VBScript and JavaScript.
All properties and methods of our controls are script-compatible. We carried out special compatibility
tests for the scripting languages.

|
|
Yes, our barcode controls are fully compatible with the .NET environment. Most
development tools (VB.NET, C#, etc.) allow you to transparently use COM and ActiveX controls.
You do not have to do anything special for that.

To encode binary data, you can use 2-D barcodes of DataMatrix or PDF417. But apart from that, two types
of linear barcodes can also encode data within the range 0..127. They are Code39 Extended and Code93 Extended.

Is it possible to encode binary data with your DataMatrix (PDF417) barcodes?
Your DataMatrix barcode ActiveX control accepts a string as the barcode value (DataMatrixCtrl1.DataToEncode). But our original barcode value is presented by an array of bytes. How should I convert our bytes' array into to the corresponding string if I want to use your component?

Yes, after you purchase a license, you will get a registration key and barcodes will be displayed without the Demo reminder.

|
There is only one limitation it is a red line with the demo reminder.
If your barcode has a crisscross pattern, it means that there is some kind of error in the process
of encoding. For example, you could have used a character invalid for this type of barcodes, or your
barcode cannot be drawn within the size you specified and you should increase the size of the barcode.
