Below are some of the VFUG’s latest tips, tricks, and
FAQ’s.
These are so fresh, they may not even be loaded into the FAQ section by the time you read this!
Stop
Crashing
VFP
If VFP crashes or hangs every time you try to start it here is something you can try to fix the problem.
First, try re-installing VFP. If that does not fix the problem and nothing else seems to work then here is a last ditch possible solution:
Run VFP from the command like this:
VFP.Exe -A
The “-A” parameter starts VFP without reading registry settings and ignores the configuration file. If VFP then loads successfully you more then likely have either a corrupted registry entry or a cross linked entry.
What you can do to possibly fix this is:
1. Back up all of your files and the entire drive and make sure your Windows registry is backed up.
2.Edit the registry (RegEdit.Exe) and delete every reference to
VFP.
3.Try starting VFP. Now if it loads then good, if not you have a bigger problem or did not delete all the registry entries. 4.If it did work the start VFP again with the “-R” parameter:
VFP.Exe -R
This will Refresh the Windows Registry and add many of the entries you will need.
You should now be in good enough shape to recover and continue. You may need to “Tweak” some settings or re-install OLE settings but at least you can use VFP. Again, this is a last ditch Tip when nothing else will work.
WARNING: Editing the Windows System registry could result in total destruction of your system if you make a mistake. The only recovery may be a total reinstall of windows.
DISCLAIMER: I in no way endorse using this method. Use it at your own risk. If you are a novice at Windows, Computers, or editing the registry do not even attempt this.

Guest Editorial...
Will future programmers suffer greatly from multiple personality disorders? Good question, and quite possibly so. It looks like the days of the single language programming environment are quickly coming to an end. In order to survive, programmers will have to learn multiple languages and learn numerous platforms. Integrated systems and integrated programming languages are quickly becoming the norm.
Let’s face it, the web (Internet/Intranet) is the future. With the on rush of the Internet has come the end of the simple one language programming era. Take a no frills web app for instance. Let’s say all you want to do is set up some simple pages on a site. What is involved? To start with you have to either rent space on a web server or construct one yourself. If you construct your own you will have to learn to be, for example, an NT Server administrator, a network administrator, a hardware technician and an Internet Information Server (IlS) administrator (plus know how to hook all this up to the Internet or even Intranet). You’re basically looking at wearing three or four hats (minimum) just to get the server running.
Now, let’s move to the software angle. Let’s say all you want to do on this server, whether local or remote, is record visitors to your site. What is involved?
OK,
of course right up front is the HTML to piuducè the web pages or maybe learn how to make Active Server Pages (ASP). Next, you will have to get to know something like VB Script or Java Script so you can handle the data. Now, what data source will you use? A text file, a Visual FoxPro data file, VB, or Access Jet engine? Then maybe an ODBC link may be in order to translate the data. And, of course, you must have that animated icon or something to make your site cool, right? OK, Java, Visual Basic, VRML or what do you want to use to create this? Getting thick fast isn’t it?
We just went through some very simple specifics on creating a simple web site. If this site is also connected to an Intranet now we have to support operating systems such as Windows NT, Windows95, or even MACs or other types of PCs. In a large corporation you would be looking at a whole MIS department. For one or two man programming shops, you’re looking at major “brain strain”. Now, to put all of this together not only requires knowledge of each aspect but also knowledge of integration techniques. And, of course, let us not forget this was all supposed to be done yesterday, right? Are you seeing my point yet?
Integrated systems and integrated programming languages are quickly becoming the norm, and that means more work to do even the simplest tasks. Very soon it will not be a matter of whatlanguage is better, Visual FoxPro, Visual Basic, Java, or whatever is your favorite, but using multiple languages in order to create an integrated environment will be required.
