Sample Programs

LEADTOOLS supports your programming endeavors with thousands of code snippets, function examples, tutorials, and demo programs.

Demo Programs

Demo programs showcase LEADTOOLS core features, and demonstrate some of the simple, yet powerful applications that can be produced with LEADTOOLS.

Demo Executables

LEADTOOLS demo executables show and allow you to manipulate basic toolkit functionality through a simple user interface. Demo executables are found on the installation path in the appropriate platform subdirectory of the \BIN\ folder (for example: C:\Program Files\LEAD Technologies\LEADTOOLS Multimedia xx\Bin\CDLL\Win32).

Demo Project Source Code

LEADTOOLS includes complete demo project source code for hundreds of LEADTOOLS features, (including those shown in demo executables). This enables you to see, manipulate, and copy demonstrated program functionality. Demo project source code is found on the installation path in the appropriate platform subdirectory of the \EXAMPLES\ folder (for example, C:\Program Files\LEAD Technologies\LEADTOOLS Multimedia xx\Examples\Ltmm\Cpp\capture).

Refer to Example Programs and Demos for a table listing the different demo source code projects and executables available.

The LEADTOOLS toolkits include complete demo project source code for hundreds of LEADTOOLS features, (including those shown in demo executables). This enables you to see, manipulate, and copy demonstrated program functionality. Demo project source code is found on the installation path in the appropriate platform subdirectory of the \EXAMPLES\ folder (for example, C:\Program Files\LEAD Technologies\LEADTOOLS  xx\Examples\CDLL). Refer to the Demo Project Source Code column in the different Feature by Platform tables of this help file for a listing of the demos available for that specific platform.  

Hosted / Online Demos

Downloadable Demos for LEADTOOLS core functionality are published to our website and updated using Microsoft ClickOnce technology. Additional demos are available under relevant subjects in  LEADTOOLS Support Forums .

Demo Tutorials

For many demo executables, LEADTOOLS also includes tutorials that walk through the demo features and provide guidelines and code snippets for programming variants and options. Demo tutorials are found in the relevant help file , listed in the Contents tab under "Features of...—  Using...Demos." "Programming with LEADTOOLS Multimedia—  How To..."

For example, the Barcode C DLL Demos are documented in Barcode C DLL WebHelp-Demos the Barcode Module help file.

LEADTOOLS Video Trainers

Getting Started video tutorials (with full audio voice-over) that walk through key coding tasks are hosted on the LEADTOOLS YouTube video channel .

Tutorial (Model) Programs

Tutorial programs are straightforward, stepwise models that show useful solutions to practical problems. You can use these as a starting point, cut and paste code, or simply review them for highlights on how to write code for a specific feature or problem. Tutorial (model) programs are found in the relevant help file , listed in the Contents tab under "Features of...—  Tutorials." "Programming with LEADTOOLS Multimedia—  How To..."

For example, a Barcode C DLL tutorial is documented in Barcode C DLL WebHelp-Tutorial the Barcode Module help file.

Documented Examples and Code Snippets

The documentation for each LEADTOOLS function reference includes an Example at the bottom of each page, with additional code snippets as needed in the Comments section. Where appropriate, these are related back to the relevant Demo and Tutorial programs.

Multimedia Code Examples are also listed in the Contents, under  "Programming with LEADTOOLS Multimedia."

For example, the Barcode C DLL function L_BarCodeRead, including code snippets, an example, and reference to additional demo project source code, is documented in Barcode C DLL WebHelp-Example the Barcode Module help file.  

LEADTOOLS IntelliSense Code Snippets

IntelliSense Code Snippets allow you to insert ready-made snippets of code into your projects. LEADTOOLS ships with many IntelliSense Code Snippets for C# and VB.NET and COM. They are automatically integrated into the Visual Studio IDE during product installation.  To use LEADTOOLS IntelliSense Code Snippets, select them from the Microsoft Code Snippet Picker .

For more information on using the Microsoft Code Snippet Picker, refer to the MSDN documentation.

LEADTOOLS Developer Support Forums

LEADTOOLS Developer Support Forums are clearly organized, support-moderated (so that all queries include solutions), and provide code tips, copy-and-paste code snippets, and solution samples along with FAQs and troubleshooting advice. Each page includes an RSS (RSS 2.0) web feed button, enabling you to subscribe to your favorite forums and stay on top of emerging issues.
