Prospero Software Products Limited 41 Athol Street Douglas Isle of Man IM1 1LA United Kingdom CONTACT: Frank Vipond PHN: +44 (0)1624-681090 FAX: +44 (0)1624-681097 EMAIL: CompuServe 100332,1257 About File PSPNUM.ZIP: ----------------------- This ZIP file contains a full working demonstration of version 1.8 of the PSPNUM VBX (a Custom Control for use with Microsoft Visual Basic V1.0 or later or with compatible environments). The PSPNUM VBX is a special type of Edit Box control. You use it only for decimal numbers or decimal numeric arrays. You specify through edit masks how you want numeric values displayed in the edit box e.g. "123.45-" or "US$123.45CR". The VBX also supports a range of operations for numbers - add, subtract etc. This VBX addresses the shortcomings of 1) the native VB 'currency' data type and of 2) floating-point data for accurate storage and manipulation of numeric field/array values. If you are familiar with decimal numeric fields/arrays from commercial programming languages such as RPG or COBOL, then the PSPNUM VBX should be both intuitive and very useful. One of the documents (see below) in the ZIP file contains a much fuller description of how different PSPNUM is from alternative numeric data types available in VB. PSPNUM1.ZIP Contents: --------------------- Use 'PKUNZIP -d PSPNUM1.ZIP' to unzip the contents with one subdirectory. Total unzipped size is approx 500K (0.5 MB) giving the following files: PSPNUM.VBX: The PSPNUM VBX (demo version). This has ALL the functionality of the production version, but only allows a limited number of instances of the PSPNUM control to be in use at any point in time. You may need to move/copy the VBX to another directory for general testing/use. PSPNUMUG.DOC: Full 40-page PSPNUM User Guide. Prepared using Microsoft Word for Windows. In particular, see sections 1.3 and Appendix B for an explanation of why PSPNUM is better than the VB 'currency' data type or floating-point fields. PSPNUMUG.PCL: Print to file of *.DOC above. Can be printed directly to any laser printer that understands Hewlett- Packard PCL (Printer Control Language). DEMO\*.*: A full VB 3.0 project with several forms showing the capabilities of PSPNUM. Open project PSPD1.MAK from within VB itself. You can regenerate PSPD1.EXE yourself or run it directly from the UNZIP directory. Further Action: --------------- PSPNUM is NOT freeware/shareware. PSPNUM1.ZIP provides enough for a very full demonstration and evaluation of the PSPNUM VBX. You may well find the demo version useful without acquiring the full production version. However we strongly believe that it is not in your best interests to use unsupported software. If you acquire the full production version of PSPNUM in terms of our license agreement, we can support you, help you, and upgrade your software if needs be. Whereas as an unlicensed user, you really are on your own. We welcome any enquiries about the PSPNUM VBX (contact details at top of this file). License and full pricing information available on request. Indicative pricing: Single License US$75, Licenses 2-10 US$25 each, further Licenses US$10 each.
