Re: [Gambas-user] Weather app in Software Farm

2017-07-16 Thread Tony Morehen

I just uploaded a version that uses the gb.gui component instead of

gb.qt5. It also has a workaround that may fix your error. That error
arises when your system does not have a systray enabled. See:

https://unix.stackexchange.com/questions/278104/app-icons-dont-appear-in-system-tray-on-linux-mint-17-3

I haven't been able to test since I'm running Manjaro. What version of
Mint are you using : Cinnamon, Mate Xfce? 17.? 18.?

Hi Tony,

I tried your program on a computer at work and got it working after adding
*gb.qt4*. Linux Mint does not have QT5 yet. I tried it a home but even after
fixing QT I got: -

*"sni-qt/5871" WARN 12:51:31.765 void
StatusNotifierItemFactory::connectToSnw() Invalid interface to SNW_SERVICE *

After 20 seconds FMain appeared but with no data.

Not sure what the problem is.

You may have hinted at the solution within your question. Have you considered 
using a Structure?

http://gambaswiki.org/wiki/lang/read :
"... reads the stream Stream as binary data whose type is specified by the Datatype 
argument."

"The returned datatype can be one of the following: NULL, Boolean, Byte, Short, Integer, Long, Pointer, Single, Float, Date, 
String, Variant, any Array, Collection or structure."

Hi Gianluigi,

You can't edit anonymous Gists once they are created, but a bit of extra  
code is
no big deal, you can just edit your code in the playground and generate a  
new link.

(GitHub has plenty of storage space. :) )

As a side note, if you happen to accidentally share sensitive data inside  
a code link
(such as passwords), you can contact the GitHub team[0] and ask them to  
delete it.
The playground itself does not store anything, so you don't need to worry  
about it.


If, in the future, you want to share some code on the playground and be  
able to edit
it later, you can log in in GitHub, create a Gist from there and then  
manually craft

a link to the playground like this :
https://gambas-playground.proko.eu/?gist=your_gist_id_here

Hope this helps. :)

Re: [Gambas-user] My quest for efficiency

2017-07-16 Thread Fernando Cabral

Thank you, Caveat [emptor?].
The code you proposed worked very, very well.
In fact, I timed it against two versions of the C program and the result
was quite good.
In C, reading from the standard input and writing to the standard output
took a trifle beyond half a second (0.6?? real time).

Meanwhile, your version in Gambas ran in 2.5?? (real time). The question
mark means little variation from trial to trial.

Out of curiosity, I wrote a Gambas version similar to the C version. Here
are the two codes:

  *Dim b As Byte*




*  While Not Eof()b = Read As ByteWrite (b + 11) As Byte  Wend*

- - - - -  - -





*  int c;  while((c = getchar()) != EOF) putchar(c + 11);*

The C version ran in 0.59 against the Gambas version that ran in 7.6
seconds (real time). Not too bad in my opinion!

Then I tried to stretch it a little bit and wrote:


*  Write (( Read As Byte) + 11) As Byte*
Alas! this is something Gambas does not understand.

These are just for the sake of experience. I am happy with the solution
Caveat proposed.
Thank you.

Salut Adrien,

now we can discuss 'Best ways to format float values' like this 

look here you can test Nando's way

https://gambas-playground.proko.eu/?gist=037e17d22f3ac93cd3da3d6ad681f713 

Thanks

Re: [Gambas-user] Best ways to format float values

2017-07-16 Thread nando_f

Rounding depends on what rounding you want.
Most people think of 5/4 rounding.
I prefer to round manually 5/4... 5 up, 4 down.

Dim n as Float = 26.6601

n = n * 100.  'n = 2666.01   ' 2 decimal points rounding
n = n + 0.5   'n = 2666.51   ' 5/4 rounding*
n = CLong(n)  'n = 2666
n = n / 100.  'n = 26.66


*If you wish to round down, do not add 0.5.  (add 0.0)
*If you wish to round up, add 0.9

If you wish to do 3 digits, then *1000 and /1000.
This works for any type of rounding scheme and any reasonable number of digits.
