How to tell between Win8 and Win10 using Fox commands?
by mbsoftwaresolutions＠mbsoftwaresolutions.com 25 May '17

25 May '17

I'm tracking the operating system used by my app. According to http://fox.wikis.com/wc.dll?Wiki~VFPFunctionOS~Wiki, it looks like you can't tell between Windows 8 and Windows 10. Ideas??? tia! --Mike

Forte Agent, when compacting folders, is a resource hog, too. I have quit doing them since I do not regain much these days anyway. I think DOSBox has also caused trouble from time to time.

It is a bother when the post is referring to a programming language that has had various versions over the years. I have also seen conversations that just give the time of each response, but who knows how long ago? Sincerely, Gene Wirchenko

[NF] XFRX V 17.1
by Paul Newton 23 May '17

23 May '17

Hi all I know that some of you use XFRX and are very enthusiastic about it. I just took a look at the "text format" functionality in the latest version (released yesterday). Running the sample code in TEXTFORMAT2SCREEN displays only the first three names from the BB-CHILD table (which contains five records) and I cannot see why. Also I cannot yet see how this functionality would be useful in a real-world scenario using FRX report designs - but I will be looking into this further. Any feedback from other users of XFRX would be welcome Paul Newton

Multiple inheritance sounds, at first, to be something that could be useful, but then, you run into the problem of which parent wins if both have a method or property of the same name. How would you handle this? Well, then, do not do that. I am a sensible person, and I would not do that. You might well be one, too. We both know that there are those who would climb Everest with it. (Because it's there.) I remember a similar fight when I was defining my form handling. I have two pairs of classes that are very similar. Here is the heading code for them: ***** Start of Code ***** * atgettext Class * @ ... get Equivalent Class (textbox) #define ATGETCLASSNAME atgettext #define ATGETPARENTCLASSNAME textboxbf * Last Modification: 2013-05-23 * * atgettext:: and atgetedit:: are practically identical. If you make * any changes to one, you will probably have to make them to the other. Oh, * for multiple inheritance (not that would not create its own headaches). * * As of 2007-05-03, the code *should* be identical except for the title * lines and the #define lines. The classes have been written to be nearly * identical by checking on the base class for some actions. This bloats the * classes just a bit, but makes it very easy to copy changes between the two * classes. define class ATGETCLASSNAME as ATGETPARENTCLASSNAME #undef ATGETCLASSNAME #undef ATGETPARENTCLASSNAME ... enddefine * atgetedit Class * @ ... get Equivalent Class (editbox) #define ATGETCLASSNAME atgetedit #define ATGETPARENTCLASSNAME editboxbf * Last Modification: 2013-05-23 * ... define class ATGETCLASSNAME as ATGETPARENTCLASSNAME #undef ATGETCLASSNAME #undef ATGETPARENTCLASSNAME ... enddefine * textboxbf Class * Basically Formatted textbox #define BFCLASSNAME textboxbf #define BFPARENTCLASSNAME textbox * Last Modification: 2014-11-17 * * textboxbf:: and editboxbf:: are practically identical. If you make * any changes to one, you will probably have to make them to the other. Oh, * for multiple inheritance (not that would not create its own headaches). * * As of 2004-07-21, the code *should* be identical except for the title * lines and the #define lines. The classes have been written to be nearly * identical by checking on the base class for some actions. This bloats the * classes just a bit, but makes it very easy to copy changes between the two * classes. ... define class BFCLASSNAME as BFPARENTCLASSNAME #undef BFCLASSNAME #undef BFPARENTCLASSNAME ... enddefine * editboxbf Class * Basically Formatted editbox #define BFCLASSNAME editboxbf #define BFPARENTCLASSNAME editbox * Last Modification: 2014-11-17 ... define class BFCLASSNAME as BFPARENTCLASSNAME #undef BFCLASSNAME #undef BFPARENTCLASSNAME ... enddefine ***** End of Code ***** Initially, the pairs of classes were just about identical since textbox and editbox have very similar functionality. I ended up making them identical so if I had to change one, I could change the other easily. Both pairs of classes have the same code. My atgettext and atgetedit classes differentiate by checking the declared type of the data value. The type declaration is in my form generation file; if not a memo, use atgettext; if a memo, use atgetedit. My textboxbf and editboxbf classes differentiate by testing of .baseclass at various points. It would have been shorter if VFP allowed one to #include executable code and have it stick. (VFP does allow #include'ing of executable code, but it ignores it.) Sincerely, Gene Wirchenko

[NF] C#: Single inheritance
by mbsoftwaresolutions＠mbsoftwaresolutions.com 22 May '17

I could have swore somebody told me DotNet was MULTIPLE inheritance, where you could have multiple parents...which I thought was really great & cool! However, my Pluralsight training video just said it's SINGLE inheritance. So what language has MULTIPLE PARENT inheritance? Java?

[NF] Windows 10 Surface Pro 3 tablet purchased from buddy; need to disconnect from his domain
by mbsoftwaresolutions＠mbsoftwaresolutions.com 18 May '17

Buddy sold me his Surface Pro 3. It's Windows 10 but still on his domain. Before disconnecting from the domain, I wanted to ask if that would lose any software currently on the computer, or what ramifications I'd have? I don't want to stay using his domain. tia, --Mike

Running Multiple Instances of VFP 9
by Paul H. Tarver 17 May '17

17 May '17

Does anyone know if there is a way to run multiple instances of the VFP development environment on the same computer. I run into this need from time to time, but I've not taken a lot of time to research it. I know I can run multiple instances of a compiled VFP program, but every time I try to open multiple VFP projects, it simply brings the existing dev window forward and opens each project within the same development environment. Short of running virtual machines, is this even possible? Paul H.
