The saying is of course “You can lead a horse to water but you cannot are it drink”
And that applies in many contexts
You can show a person a solution to a problem but they’ll still refuse it – for whatever reason they have.
Sometimes the real saying that should be applied is “You can only help someone if they want help”
Again, despite seeming to ask for it, when they get an offer of help that isnt EXACTLY what they wanted they’ll refuse the help.… Read the rest
Long ago I wrote about byref & byval
Apparently this wasnt widely read not even by some long standing members of the community as I still see completely wrong explanations of bevel & byref persist.
First you have to understand that there are two types of VARIABLES.
VALUE types and REFERENCE types.
With a VALUE type the compiler sees there is space in memory set aside when your program runs to hold a value – a number a floating point value etc.… Read the rest
I’ll publish results of this survey
Not sure how soon as I accumulate results slowly since I cant post on Xojo’s official forums
Was helping a fellow Xojo user to try & sort out why updating to a new version of Xojo broke their code.
The code still compiled fine. But it just didnt work as expected any longer.
And it turns out that in some classes Xojo changed a get/set pair of methods, which can be overloaded by a subclass, into actual computed properties, that cant be.… Read the rest
In the case I described the code is in a subclass a Xojo class
The idea here is to INSERT a new subclass between the existing subclass and the new one. And the newly inserted subclass will expose things in a way the OLD existing code wont break
So we never touch the old code
We just modify the inheritance chain in a way we can then alter how things behave
So in his case we can add a new subclass of EmailMessage that exposes the Source as a Method pair ( get & set) and then make the existing class inherit from our new class
And the existing code will then JUST work without ever having had to alter any of it
Next time you have an issue like this consider that as an option !
For the past 3 days I’ve been on a training course and today I got my certification as a CSIA level 1 instructor !!!!!
The other day I was helping a friend with some code that worked fine in several versions of Xojo but then in a newer one wouldn’t compile
Seems he found a compiler regression Whether this _should_ have been caught by regression tests etc is an entirely different question.
It exists. And now his large project doesn’t compile.… Read the rest
Was chatting with a potential client. And they are new to Xojo.
When I mentioned that I had worked at Xojo Inc for more than 10 years they didn’t believe me. And they asked for some proof. I had never encountered this before.
So here’s a quick few references where you can see that I was once a member of their development team.… Read the rest
After a bizarre series of bad timing, DO node failures & crappy coincidence INN is back up & running
There may still be glitches
if you’ve EVER tried to debug a Xojo Script its truly a pain in the rear end
Since one of my current projects requires a lot of Xojo Script that became really apparent and really annoying
So, for this project, we made a XojoScript debugger 😛
You can run & single step. And with each step the values of all variables in scope will be reported; where possible.… Read the rest
