About QRZDEMO.EXE

QRZDEMO.EXE is a sample program written in Microsoft Visual Basic Version 3.0.  In the \win3\src directory of this CDROM you will find the complete source to QRZDEMO which serves as an example program on how to use the QRZ Dynamic Link Library,QRZDLL.DLL.

QRZDEMO is a simple application which uses many of the same techniques as QRZII.EXE, the QRZ Callsign Database search and retrieval program.

QRZDEMO uses no VBXs and thus can be demonstrated on the standard edition of Visual Basic 3.0.  QRZII was written using the Professional version of VB 3.0 which includes a few more whizzy objects like 3D buttons, panels and several other capabilities which werent used by QRZII.

The QRZDEMO application consists of two modules, QRZDEMO.FRM and GLOBAL.BAS.   The File GLOBAL.BAS will be particularly useful to your development effort since it contains all of the Global Const defines that QRZDLL recognizes as well as the Function and Sub declarations.  In this example, GLOBAL.BAS contains no executable statements or code, only declarations.

The best example of how to use QRZDLL comes from the source code itself.  All of the QRZDEMO source code is saved in ASCII format so it may be examined using Notepad.exe or any other editor.

If you have suggestions for additional features for QRZDLL, or if you have a program which you have written using it, please drop me a line and tell me about it.  I can be reached by e-mail at:  aa7bq@qrz.com and welcome your comments.  We would especially like to include your software on the QRZ disc, especially if it does a better job than QRZII ! ! !
