Introduction

LMD Validators Pack provides a set of components and classes to implement client-side validation of data input in an elegant and clear way without writing much code (often without any code at all). The two main tasks of client-side validation are:

• to check for validity a value entered by a user into some input control
• to provide feedback about validation results (e.g. to indicate an error) in some way

• Compatible with Delphi and C++ Builder 2009 and better including 64bit support for XE2 and higher! The next Delphi/C++Builder release will be supported almost immediately after public availability.
• Supported IDEs:
• Delphi 2009 and better
• C++ Builder 2009 and better
• All corresponding Studio Products (CRS 2009 and better)
• Supported operating systems: Win 2000 or better (including Windows 7/8/10)
• Full sourcecode of all controls included. Registered versions include NG util to compile packages on target system.
• Extensive demo projects with sourcecode
• Free updates via Internet
• A Site License covers unlimited number of developers in same organization at one location
• Free technical support via newsgroup (news.lmdtools.com), e-mail, fax or mail;
• Also available as part of NG Complete or LMD VCL Complete.
