Unexpected External Call Back...

I have an inherited Mac, 4D v15.4 database where a certain interprocess variable was unexpectedly undefined. Then one method said it could not be executed. After setting a couple of key trace statements, I noticed that the variable was not populated (the smoking gun) and that "External Call

Unexpected Command Key Shortcuts (15.4)

It seems that the 4D v15.4 command key shortcuts changed on me while in use…. Restoring to a factory preset did not help the situation. Note that "Go to line" is Command-L instead of opening a form, the usual behavior. The unexpected shortcuts using v15.4 Client/Server:

Andreas, can you tell me what code you used that generated an error? I'd like to reproduce that. Okay, super weird findings. I'm not sure what the behavior is meant to be. Yesterday, I spent 5-10 minutes setting up a new scratch database to test this stuff out a bit. I created a preemptive

Tim: "4D v12.6 (final version) was released October 8th 2013. Windows 10 was initially released July 20th 2015." Thanks for that info. I checked out the cert matrix for 12.5 vs 12.6 and 12.6 is a no go with 8.1 but, as you point illustrate, Win 10 didn't exist when 12.6 shipped. Some users have

Thanks! I’ll be using both of those tips. I haven’t used On Error Call much, but will look into it. At a minimum, I want: “On Error, don’t crash my server!" Sannyasin Siddhanathaswami On Apr 7, 2017, 9:12 AM -1000, wrote: Sannyasin, Two things: I make it a habit to check for -1 anywhere I'm

Sannyasin, Two things: I make it a habit to check for -1 anywhere I'm using Find in array... it just bites me if I don't. For methods that run on the server, or even better for processes that run on the server, wrap them in an On err call method that lets you manage the errors yourself. Like not

Re: 4D Compiler

Nigel, I went through a similar process several years ago when I changed the compile settings on a rather extensive database to 'all variables are typed.' I forget the number but it was a lot. Daunting. I forget how much time I spent on it but it turned out to be much less than I thought it

Aloha, Yes. The crash did happen when accessing an array with a negative index! If that’s the only thing that causes the crash, I can be extra careful about that and do checks. Thanks for pointing this out. And yes, I wrote that serious bug. :) As this is an internal database for our

Re: 4D V12.5 OK with Windows 10

Hi Doug, We ship and use v12.6 on Windows 10. One problem 12.6 has that a 4Dlink file to the server won't remember name and password. (This is something we use for automated testing, so we run those tests with 12.5). Jim On Wed, Apr 5, 2017 at 6:48 PM, Douglas von Roeder via 4D_Tech <

RE: 4D Compiler

69,000 typing errors will not necessarily require 69,000 code modifications... For example, if you have an untyped variable $a in a method, and in that method you use the variable 100 times. With 'all variables are typed' this would be reported as 100 typing errors. If you type that variable at

Re: 4D Compiler

This is where strict variable nomenclature with typing info helps a lot. You can easily create a method that can gather all locals in a piece of code, and add the declarations at the top of a method. You can even apply that automatically using METHOD GET CODE and METHOD SET CODE. OTOH if you have

I have not read any more of this thread... I am not able to use these commands... What should happen: - 4D should throw an error (interseptable by On Err) on the computer that caused the problem (i.e. client or server) - abort the illegal code block. SO if the error occurs inside some looping

RE: 4D Server Crashes When Tracing Buggy Web Connection Code

To be honest, I don't understand these problems. Our main product relies heavily on the 4D webserver on the server, for years. So far there aren't any serious problems. If there are any, we wouldn't use 4D anymore. And running the webserver on a client isn't an option for us. The only problem

Tim I bow to your knowledge on this. I only go back as far as version 2.5 of 4D and in my first year of work did not have the compiler. I suspect there is little of the original David Hemmo code in the current compiler now. > On 7 Apr 2017, at 02:34, Tim Nevels via 4D_Tech
