Re: Need help identifying a crash source

Kirk, something seems odd about this code. Toward the end you have: If ($key#"") QUERY([KVP];[KVP]key=$key;*) QUERY([KVP]; & ;[KVP]dir=$dir;*) QUERY([KVP]) End if That last Query([Table]) would bring up the query editor. I’ve never tried doing that at the end of a string of Query paramete

Need help identifying a crash source

I need some ideas on a problem. I'm getting a crash when a method runs. The method itself isn't the issue, I think, because it gets called literally hundreds of times in a given session. Here it is: C_TEXT($1;$2;$dir;$key) $key:=$1 $dir:="" If (Count parameters=2) $dir:=$2 End if ASSERT($ke

I always get amused whenever the discussion on the NUG turns to the evils of global variables. Lacking a computer science background most of the discussions in this vain go way over my head. I am a self taught 4D guy who over the years, for reasons I know not why, have taken a minimalist approac

Thanks for jumping in, Tim. I am actually using V16 and so I generally use the V16 documentation. But the link that Keisuke provided me to explain RESIZE FORM WINDOW happened to be a link to V15.4 documentation, immediately before CALL FORM arrived on the scene. So I was in that link when I the

Hi Jim, How do you avoid responding with a web page? Can you give a simple example for me to start with? For example, the first time they click the Confirm button in an email, we might still open a web page to give them some feedback. Then, they can decide they don't want the extra feedback of th

Re: Put a button in an email that won't open a web page

Without knowing the details of what you are doing I can only say that the button will just act like any URL to a server. What you do with the URL and respond to it is entirely up to how the server responds. I regularly send out emails with buttons linked to a URL. I use 4D Webserver and trap the U

Nigel, Nice post. I very much agree with pretty much all your points. A few things I'll add: Functions: yes! A lot of IP vars I see in old code are used to make values available that used to take measurable time to derive. Lots of them can be replaced with a short function to just go get the curre

Some friends saw them here recently and said the show was very good. The album they are supporting is on iTunes - you can stream it with a subscription. Esp. interesting as I'm reading Weigel's book, "the Show That Never Ends." Cranky, perfectionistic old bastard Fripp - would fit right in here. O

Hey Peter, just a quick response to a couple of things: * Don't really know what you mean by 3G and 4G languages. If memory serves me, this was more of a marketing term from the 1980s or so than any kind of real technical distinction. * No. You do not need classes. Modules do not require OOP, OO

Global Variables. Regardless of the relative merits of Arrays vs Object. I would like to relay my dislike in general of Global variables. I have been working with 4D since before the concept existed-since 4D V2(Globals came in with V3). Yes i am one of the old boys. Back then we did not have m
