 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 module
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 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.q
