Demo and Sample Code for VB andC/C++

TAL Bar Code DLL Demo "Unofficial" demo for TAL Code 39 Bar Code DLL. Includes sample source code for Visual Basic 6 and C/C++.

Please note: This demo is for intermediate to advanced programmers that are interested in reviewing sample VB and C++ source code to learn how the TAL Bar Code DLLs are called from an application. This demo includes sample source code for VB 6 and C/C++ only (32 bit).

We are trying to show many different techniques in the above demo therefore there is quite a bit of code in the source files. See below for a very simple demo that shows just the basics.

Simple Visual Basic Demo.  This file contains a very simple Visual Basic 6 program that demonstrates how to print bar codes directly to a printer by calling the TAL Bar Code DLLs.

Intermediate Visual Basic Demo.  This file contains an intermediate level Visual Basic 6 program that demonstrates simple label printing and DLL calling conventions.

Visual Basic Bar Code Class Demo. This file contains a sample VB class module that wraps up the functionality of the linear TAL Bar Code DLLs in a Visual Basic Class. This code sample also contains an example routine that shows how to convert the metafiles produced by the TAL Bar Code DLLs to a Picture object that is compatible with a VB PictureBox or the VB PaintPicture method.

Note:   All of the above demo files only contain a sample of the Code 39 DLL. If you would like to use any of the other DLLs you will need to purchase the commercial release of the DLLs. The B-Coder Demo is easier to use if you are only interested in demonstrating the quality of the bar codes created by the DLLs. B-Coder is a very simple application program that uses the same bar code graphic generation code as the DLLs.

Simple Visual Basic.Net Demo. This file contains a very basic example of how to call the TAL bar code DLLs from a VB Dot Net program and both display and print bar codes. The file is a ZIP file containing a complete VB Dot Net project along with a demo version of the TAL Code 39 bar code DLL (TALC3932.DLL).

Note: after extracting the project files from the ZIP file, you will need to copy the DLL file (TALC3932.DLL) into your C:\Windows\System file folder before running the VB Dot Net sample code.

Access Examples

Access 97 DLL Demo. This example demonstrates how to call the TAL Bar Code DLLs from MS Access.

This sample database shows how to create bar codes and generate reports and labels. Note: This file only contains a demo of the Code 39 DLL. If you would like to use this database with any of the other DLLs you will need to purchase the commercial release of the DLLs.

Access 97 DLL database example. This file does not contain any sample DLLs, therefore you must have the commercial release of the TAL Bar Code DLLs to use this example.
