| IIS7 Localhost port binding | | Author: Wil van Antwerpen |
| Last Update: 08/02/2023 | | Company: Antwise Solutions |
| |
| IIS Web services on Windows 7 and higher does not just bind to 127.0.0.1 when binding itself but binds itself to any available IP address on your host, not convenient if you want to bind something on that same ports to for example 127.0.0.2 |
| Interactive XAML with codejock | | Author: Wil van Antwerpen |

This article discusses some methods on how to make your codejock XAML objects interactive.
Unfortunately at this time there are some limitations in what you can do, but I hope that this how-to will help in discovering better and more complete methods for doing this. |
| Codejock Hi DPI Icons | | Author: Wil van Antwerpen |
| Last Update: 09/03/2016 | | Company: Antwise Solutions |
| |
| Codejock supports the use of icons that contain images for multiple sizes. DAWs dynamic loading of these icons unfortunately just uses the first icon and then depends on dynamic resizing to show the icon at the desired size. Scaling down a 48 pixel icon to 16 pixels looks VERY different from a properly designed 16x16 icon. We show you how-to write code that uses the icons dynamically. |

The Winprint II classes are great, but sometimes you want to extend them a little on customer request.
Here Bob shows us how you can easily extend a Winprint II report to not only be able to print preview and print, but also export to a CSV file. |
| Decimal Separator problems | | Author: Wil van Antwerpen |
| Last Update: 28/02/2004 | | Company: Antwise Solutions |
| |
On some computers the decimal separator on the numerical keypad doesn't seem to respect the regional settings of your language. As an example for dutch the decimal separator is a comma (",") whereas for the US this is a dot (".")
In certain conditions, if you try to use the decimal separator key in a numerical field, pressing the key generates an errorbeep instead of the comma. |
| Dialog Callback | | Author: Bob Worsley |
| Last Update: 17/07/2003 | | |
| |
This paper explains how you can write your own class based on callback logic.
The discussed example talks about implementing a callback for a dialog, but you could use this same technique anywhere.
It is a very nice explanation of how callbacks work in VDF. |
| Comparing padded strings | | Author: Wil van Antwerpen |
| Last Update: 13/11/2002 | | Company: Antwise Solutions |
| |
Comparing strings padded with spaces in DataFlex might not exactly work as you would have expected as it is a little bit different from other programming languages.
You have to be aware that comparing 'abcd' to 'abcd ' always results to a (True) condition |
| Creating an NT service for a VDF program | | Author: Bob Worsley |
| Last Update: 18/08/2002 | | |
| |
| NT services are something that I've had extensive experience with, on both NT-4 and Windows 2000. This article is a complete guide, including code, to installing and running a VDF program as a service. The "code" is a scheduler that once the service is running, kicks off a program at a required time or periodically throughout the day. |
| How to use Microsoft Agent inside VDF applications | | Author: Franco Spinella |
| Last Update: 01/08/2002 | | Company: DATAFLEX SERVICE ITALIA SRL |

Here is an IDE compatible view that shows how to use the class "cAGENT" generated by FlexCOM to integrate MSAGENTS inside your VDF applications.
The view was built while testing all of the MSAgents functions, so please don't comment about the layout of the view, it's only for testing purposes. Please read more before you start using it.... |
| Retrieve lost objects | | Author: Wil van Antwerpen |
| Last Update: 03/11/2001 | | Company: Antwise Solutions |

| A tabpage in VDF sometimes looses one or more of its objects. This usually happens after a user clears the entire view. This document describes how to redisplay those lost objects. |
| Retain in VDF | | Author: Peter Bosch |
| Last Update: 27/10/2000 | | Company: info trans Logistik Systems GmbH |
| |
| Do you remember the item_option "retain" from console mode DataFlex? This is no longer a supported technique in VDF, until now! This white paper describes how you can still make use of the retain field_option in VDF (DD_RETAIN) by adding a few lines of code to your subclass structure. |
| The dbList class unmystified | | Author: Wil van Antwerpen |
| Last Update: 04/07/2000 | | Company: Antwise Solutions |

| This white paper is about the inner workings of the dbList class. Understanding what happens when you press a button that invokes a lookup can help in customizing this class. An online version of the paper is also available. |
| Panel gets covered by windows taskbar | | Author: Wil van Antwerpen |
| Last Update: 09/03/2000 | | Company: Antwise Solutions |
| |
This article explains how to fix the problem that can occur if you have a view with a dbform object and a selection list near the bottom of the screen. Popping up the selection list will locate the panel in a way that the buttons are underneath the windows taskbar.
This only applies to VDF4/VDF5/VDF6. This behaviour is fixed in VDF7. |
| Multi-homed system in MS SQL Server | | Author: Frank G. Vandervelpen |
| Last Update: 17/11/1999 | | Company: Velpe Development bvba |
| |
| This white paper describes a way to tackle the problem that arises when you want to convert a multi-homed DataFlex database to MS SQL Server. By multi-homed we mean a database with shared datafiles in one directory and specific company-related datafiles in their own seperate directory |
| Prevent Status Panels losing the focus | | Author: Geoff Furlong |
| Last Update: 20/10/1999 | | Company: MSG Business Systems Ltd. |
| |
| The status panel used in BPOs and Winprint will lose its focus when switching to other applications and back. The result is that the application appears to have locked up while it is in fact still running the report or business code. This describes a fix for the problem. |
| Creating a multilingual application | | Author: Peter Mustoe |
| Last Update: 20/10/1999 | | Company: FocusTree Ltd |
| |
The zip-file contains a Word97 document and a password package on how I implemented a top level function in VDF for multi-language changes for ALL visual objects. The database fields label naming is performed by using the method explained in the final chapter of the "Mastering Visual Dataflex" book (not published in here).
If these 2 methods are adopted a full language translation facility can be included in ALL your VDF applications, with very little code. |
| VDF running as a Windows NT Service | | Author: Frank G. Vandervelpen |
| Last Update: 20/09/1999 | | Company: Velpe Development bvba |
| |
| This document explains step by step how to set up a Windows NT machine so that it is able to run a VDF application as an NT service. This means that the application will automatically run in the background when the computer is booted. The VDF application will even run without a logon. |
