[Gambas-user] Copying a folder and subfolders

[neil lewis]

Hi All,

I'm sure it's fairly trivial, but here goes.

I need to copy the contents of a folder which may include subfolders
(and maybe even sub-subfolders).
The notes for COPY say it can't be used recursively, so what's the best
way to do this?
I've checked the manual and the wiki and so far I can find no examples
or suggestions.

I had a similar problem with the MKDIR function that gambas has where I
couldnt create subdirectories recursively.
I solved this by just using the SHELL command though you could use EXEC as
well.

This way you can add your own options to the copy command.

Hope this helps,

use this command :

Benoit,

Questions:
(1) Does the following...

PRIVATE my_array [4096, 16] as STRING

...occupy a static section of RAM or
is it dymanic depending on the size of string actually stored
in each element ?? (Remalloc'd every time there is an assignment?)

(2) Are byte,integer arrays MALLOC'd in a static section of RAM once??

Thanks
-Fernando

The array itself is statically allocated in your class, but a string is just a
pointer to a malloc() allocation.

By doing this, an object of your class will take at least 4096 * 16 * 4 = 256
Kb !

What do you mean by being "malloc'd" in a static section of ram once ???

There are two types of arrays in Gambas:

- "static arrays", declared with DIM array[x, y] AS Type
- "dynamic arrays", declared with DIM array AS NEW Type[x, y]

The dynamic arrays are true Gambas objects, like in Java, but not static ones.
Static arrays are allocated directly in the object they are declared (or in a
temporary allocation if you declared them as local variables in a method).

Thank you.

About item (2) below - what I meant was:

would...
my_array [1234,12] = "HELLO"
my_array [1234,12] = "Good Bye"

perform a re-malloc to lengthen the string space requirements
because line 2 is longer than line 1 ?

No. The string contents is allocated in its own place. The array contents are
just pointers to these strings.

Benoit,

My transition from VB to GAMBAS is progressing.
I want to use .ADD and .CLEAR for an array
but the syntax and usage eludes me.

If I do the following...

PRIVATE my_array [4096] as SHORT

I am having a difficulty using .CLEAR

my_array.clear reports it is not an object

I know I am missing something in my understanding here.
Can you aid in clearing my brain fog?


Thank you
-Fernando

I can just repeat what I said in my previous mail:
- DIM array[xx] AS Type are static arrays, not objects.
- DIM array AS NEW Type[xx] are dynamic arrays, i.e. true Gambas objects.

Is this wanted or just "something we cannot make better":

In practice, there are many cases where something counts from 0 but is
interpreted like 1, i. e. you will have to write a "- 1" here and there.

If you leave out the space, it is interpreted as a "-1" value, thus
leading to error messages.

Example:

...
Timer1.Delay = 4000
Timer1.Enabled = True
....

Question:

During the 4 seconds that the Timer is ticking...
what is the appropriate way to reset the count to start over?

I know I could Disable then Enable, but that is 2 lines of code.
Would

Timer1.Delay = 4000

restart it while enabled?

Yes. At least the way I wrote the Timer class in Qt.
