Re: String Reference to Object

TheTable.clcode Well, I don't understand this at all. "Use" is a VFP command that only opens a table. The following works fine for me: CLOSE TABLES ALL ccli = "C:\Some Path To\SomeTable.dbf" USE (ccli) && table is now open EVALUATE() applies when the parameter you feed it is the name of an object or a variable that stores the name of another variable. You can do: var1 = 3 var2 = "var1" ? EVALUATE(var2) && 3 And you can do: myarray = "aList" oMyObj.AddProperty(myarray) ? ALEN(oMyObj.&myarray.,1) && 1 But if you want to do this: mytable = "foo" myfield = "bar" ? mytable.myfield Then you need to do: ? &mytable..&myfield A [table].[field] reference is not an object reference and can't be treated like one. It's a thing unto itself. Ken Dibble www.stic-cil.org

At any rate, I want to avoid WITH, because, 1) it gets messy for complicated statements and 2) I might need more than one different reference variable. Sincerely, Gene Wirchenko

String Reference to Object
by Gene Wirchenko 15 Feb '18

15 Feb '18

Dear Foxers: I sometimes have a "reference" to an object that is in the form of a string variable. I have used &reference..referredto Is there a better way of doing this? (reference).referredto would be nice, but it does not compile. Sincerely, Gene Wirchenko

I was hoping to avoid evaluate(), but your third way makes sense. I will check if it works in all the contexts I am thinking of. (I was using "object" and "reference" rather loosely.)

New Term: Zombie Language

Did anyone catch this article about "Zombie Languages"? https://www.techrepublic.com/article/zombie-programming-languages-could-visu al-basic-be-the-next-cobol/?ftag=TRE684d531 <https://www.techrepublic.com/article/zombie-programming-languages-could-vis ual-basic-be-the-next-cobol/?ftag=TRE684d531&bhid=19995525687222274123473679 288983> &bhid=19995525687222274123473679288983 While the article focuses on Visual Basic, I think VFP qualifies under their definition: Zombie Languages: "Those old developer favorites that refuse to die" To be honest, it makes all of us FoxPro coders cool again: We are all "Zombie Wranglers!" ~~~~~~~ Pull Quote ~~~~~~~ James Milligan also drew parallels with the perennial demand for programmers skilled in venerable mainframe programming language COBOL, a language older than The Beatles. "Other languages which continue to be widely used despite running legacy systems include COBOL. It's known that COBOL tends to be preferred in business, finance and administrative systems due to its efficiency in handling large volumes of data - so it's predicted to remain popular across these sectors." ~~~~~~~~~~~~~~~~~~~~~~~ Paul --- StripMime Report -- processed MIME parts --- multipart/alternative text/plain (text body -- kept) text/html ---

[NF] Camtasia for producing demos with video and callouts on screen
by mbsoftwaresolutions＠mbsoftwaresolutions.com 14 Feb '18

14 Feb '18

Used to use Qarbon's ViewletBuilder years ago but that uses/used Flash so I stopped and then have been using TechSmith's SnagIt capture for the past couple years. SnagIt is great for recording live demos but it doesn't allow me to add on-screen annotations the demo like Qarbon's Viewletbuilder did. I was thinking of pulling the trigger on Camtasia but wanted to solicit the list's comments about what they use for creating such annotated demos. tia, --Michael

Hi All Any advice on how to post some variable to a HTTPS hosted web page and capture the resulting HTML? I was hoping to use SPS VFPConnection but it returns a SSL error? TIA Chris. --- StripMime Report -- processed MIME parts --- multipart/alternative text/plain (text body -- kept) text/html ---
