What programmable applications will work with the DLLs?

The DLLs can be used with any programmable application that can call a DLL and supports Windows MetaFile graphics. WMFs are the native graphic format for Windows and are fully supported by VB, C/C++, Access, PowerBuilder, FoxPro, Word and other popular programmable applications.

Are barcodes generated by TALtech software better than barcode fonts?

Yes. In short, barcodes generated by TALtech software are much better than barcode fonts. In fact, GS1 (formally the Uniform Code Council) does not recommend the use of fonts.

" Barcode fonts have been known to create EAN/UPC symbols with serious design defects. The problems may be caused by the design of the font, an operator input, or a combination of both."

"Extreme caution should be used when producing EAN/UPC symbols with barcode fonts."

- UCC Guidelines for Providers of EAN/UPC Symbol Design Software.

Fonts have limited ability to manipulate the size of individual characters (distortion), spacing between the characters (kerning) and the possibility of font or resolution substitution at the output stage. However there are many other problems with barcode fonts. The user cannot specify the module (bar) width exactly in printer dots. Fonts do not support Bar Width Reduction. Nor do they support many of the features specific to bar code symbols such as Bearer Bars, Quiet Zones, independent symbol height and module (bar) width specification, symbol rotation and support for binary data (including ACSII nulls in Code 128, Code 39, Code 93 and PDF 417).

In addition, most fonts do not automatically calculate and add check digits and other security features to barcodes. To add check digits you would need a separate application that calculates the check digits first before you create the barcodes.

Will I receive updates to products that I have already purchased?

Minor Update
Occasionally we will update a product to fix a problem or we will add a new feature. For all minor releases - you can simply download the latest version of your software, uninstall the existing copy and then install the new version. You should not need to reenter the unlock key and there is no cost for the update.

Major Update
TALtech may charge an upgrade fee for major upgrades. Once you've paid the upgrade fee you are entitled to free minor upgrades for that release stream. For example, if you pay the upgrade fee for B-Coder 4.0 (from B-Coder 3.x), you will be entitled to all minor upgrades in the 4.x release stream.

Is Technical Support available if I need help?

Yes. Not only is the software extremely easy to use, it also comes with unlimited FREE technical support by phone, fax and email, a clearly written manual and on-line help. To ensure your satisfaction, all TAL software products are covered by a 90-day unconditional money-back guarantee.

PC Has No RS232 Ports? What to Do?

The Short Answer:

Purchase a “RS232 to USB Adapter” at any office supply store or (typically under $10) and follow the instructions that come with it to install it. (Look for ones that use either a FTDI or Prolific chipset.) After you install it, look in the Windows Device Manager to see what COM Port number was assigned to the adapter (typically COM3, COM4, etc.) and then use it just like a built in RS232 serial port.

The Long Answer:

Although USB stands for “Universal Serial Bus,” the USB interface does not work like old school RS232 serial ports. Like RS232 serial ports, the USB ports on a PC are designed for interfacing external devices. However, any device that is designed to connect to a USB port must come with a Windows device driver that provides a software interface to the device. Practically any device can be designed to connect to a USB port as long as the device is supplied with an appropriate driver.

As a result of the USB interface design, there is no way for a software application to open up a USB port and communicate with any device the same way that you can with a RS232 serial port. Any software that communicates with a particular piece of USB hardware must do so through the driver that was designed to work with the hardware.

Many new laptop computers and some desktop models are now shipped without RS232 serial ports and are equipped with multiple USB ports instead. Fortunately, if you have a device that connects to a RS232 serial port, and you need to connect this device to a PC that does not have any RS232 serial ports, there are many solutions available that are both easy and inexpensive. A number of companies sell single port and multi-port USB to RS232 adapters that connect to a PC through a USB port.

All of these adapters are supplied with a Windows device driver that gets installed on your PC. The device driver software causes the PC to treat the USB to RS232 converter as if it were a built-in RS232 serial port installed on the motherboard of the computer. To accomplish this, the driver for the adapter creates a “Virtual COM port” in Windows that behaves exactly like a physical COM port built into the motherboard.

Single-port USB to RS232 adapters are available at most computer or office supply stores and on line at for under $10. Multi-port add-on adapters also are widely available at reasonable prices. All of these products will work just fine with any Windows-based serial communications software including our WinWedge, TCP-Com, COM-File and BC-Wedge software products.


All you need to do is to:

• Purchase the USB to RS232 adapter
• Install the driver that comes with it
• Plug the adapter into a USB port on your PC
• Determine the COM port number by looking in the Windows Device Manager
• And, finally, connect the RS232 device to the adapter.

The new serial port should be automatically recognized by Windows and assigned a COM port number (typically COM3 or COM4). Even though the new serial port is not built into the system, Windows will treat the port as if it were, and any standard serial communications software will be able to communicate through the port exactly the same way as if it were a built-in COM port.


Although a search on or the Internet for “USB to RS232 Adapter” will turn up dozens of different makes and models, there are two primary companies that make the chipsets and the driver software for the majority of adapters. One is FTDI and the other is Prolific. Both of these companies produce very high quality driver software for all versions of Windows. In addition, if your adapter uses a chipset from one of these companies, and your PC is connected to the Internet, Windows will automatically download and install the driver for the adapter the first time you connect the adapter to a USB port on your PC – literally “plug and play”. Chipsets from other companies may not be as reliable or as easy to install as those from FTDI or Prolific.

"TALtech Bar Code ActiveX Control has all the features necessary to easily add professional-quality bar codes to Windows applications. A well designed product that produces professional bar codes that print quickly and scan accurately. TALtech provides example code within VB projects, and you also get sample VBA applications in Access, Excel and Word. I would like to see more OCX publishers follow TALtech's example."
