Visitors from Germany

Recently I had both Christian Schmitz and one of my clients from Germany visit

Christian and I spent his first full day in Canada touring about to the Royal Tyrell Museum and some of the sights on thee way out. Weather was crappy so we didnt spend a lot of time outside.

At the end of the day we got together with several other Xojo users at a local restaurant and enjoyed a nice meal and discussions around all kinds of things.

Spectacular !

Last night the northern lights were out in full force.
Walked to the end of the deck and WOW !
We took some pictures but they didnt come out nearly as nicely as the ones my youngest took (like this)

Truly an awesome display

Copy & paste is not a code reuse strategy

Code reuse is an admirable goal for any developer.

Being able to re-use well written well tested code is a good thing.

Especially if you can reuse it across multiple facets of one project, or across several projects.

And I wouldn’t be surprised if a lot of people start out reusing code using copy paste from one place to another.

However, copy paste isn’t usually a well regarded code reuse technique.

Why not ? Stack overflow wrote a blog about the reasons. You might copy & paste someone else’ insecure code into your projects and thereby introduce security vulnerabilities. That’s certainly a possibility.

But what if you’re just copying & pasting your own code around ? Where’s the harm ?

Suppose you have some code you really think is top notch. And you want to reuse it over & over. Suppose you want to reuse it in the event handler of numerous controls across several projects in Xojo.

And sometime later you find there’s a bug in it.

Now how many places do you have to fix in one project ? Or worse across many projects ?

This is where copy paste as a code reuse technique can cause you extra work.

You have to find & fix all that code in every project you’ve used it in.

I’ve been using externals in SVN (yes I still use SVN)

And in every project that uses these shared modules its a simple “update” and they have all the latest code from all the shared items.

Git has similar capabilities.

All good things come to an end

Some time ago Bob had said he would let the domain registration for BKeeney Briefs lapse. Today it finally came home to roost.

Trying to visit gets you one of several things.

What I got was a domain name squatter site trying to sell me the name.

Sad to see that finally happen but with Bob’s employment changing from contractor to full time employee its not surprising.

And, with this change, another one bites the dust somehow seems strangely appropriate.

Thanks for everything Bob !

Bit in the ass by API 2

Was tracking down a bug in my app and couldnt figure out what was wrong initially.

All the code seemed right but setting a value to code like

value = string.ToInteger

seemed to be the culprit. Sure enough the string contained a value like 3.0e+2 (an integer expressed in exponential form) But the docs say

String.ToInteger

Method

Returns the integer equivalent of the source string. This function is the same as the Val function but is international-savvy.

But experience was telling me this wasnt true

So a quick test in 2021r2.1 with

Dim s As String = "3.0e+2"

Dim i1 As Int32 = Val(s)
Dim i2 As Int32 = s.Val
Dim i3 As Int32 = s.ToInteger

Break

shows that indeed i1 = 300, i2 = 300, and i3 is 3 not 300 like I would have expected. I changed my use of ToInteger to Val and things work as expected.

Be careful out there

Survey

If youre one of the people who didnt get the Xojo Experience survey there’s one thats a lot alike at INN

Filetype help

On the forums someone is looking for a way to identify what kind of file they are dealing with. And then a way to “sort” knowing those types.

The suggestion given is to look at each extension in a simple way

But, you can get away without ever having to look at the extension. Folderitem already assigns a TYPE IF there is a filetype defined that matches.

You can use this built in ability to do many things.

I posted about this on INN along with a sample project

Help keep your code sanity

Ever think to yourself “Oh I have this project to do and I’ll just cut and paste the code from there and tweak it?” And now you have two copies that are a lot alike but maybe not exactly the same.

And then you do this over & over and now you have many copies of that code?

How do you deal with issues when you find them ?

Which copy is the newest & the most correct ? And which one is the right good copy to use as the basis for yet another copy ?

I’ll admit that I will copy & paste code to examine it. Play with it to see how it breaks. And then I throw it away and fix the real single working copy that IS the master for all others.

And there are some neat tools for this like Snippets for BitBucket Server

Copy & paste coding is fast. Repetitive. And it has issues. Which is why copy-paste programming is used mostly as a negative comment on coding style.

And it can be dangerous

If you have the ability to avoid it by using submodules, includes, sub-projects in whatever version control system you’re using (you ARE using version control right?), or similar mechanisms I’d encourage you to do so.

It will help you avoid the proliferation of many different versions of the same code in all your projects.

And when you need to fix the code you can fix one copy and all your other projects can be updated with it.
