QUESTION
I'm trying to write a program, in which i have to delete and insert elements in a linked list. I have problems when I delete and after that insert. In particular if i print the list after delete-insert, i print a loop. And also, if i delete the first element i think i delete the entire list.
These are the two function, but i don't know where it's the problem (sorry for the italian comments)

can anyone help me figure out what's wrong with the code? links
not working, if you click on it nothing happens. I thought I left some tags open but I checked with https://validator.w3.org and there are no such errors! What could be the problem?
I have seen the other questions and answers related to this topic but they did not help me.

ANSWER
Answered 2020-Aug-26 at 07:24It's because of the z-index
in your css. Links with negative z-index are unclickable, its better to remove the z-index: -1
from your *
-selector.
Or you can add an additional selector for the -Tags to your style:

i'm new in vba and i would ask something about a VBA code that i made.
I've already read this link: VBA - Match Column Data and paste but it's not good for my needs.
My target is match column E with column F and give the description inside rows in G to paste in column H.
To get an msg box error if the match is false.
my problem is that the msg box appear always on my desk without matching.
Which is my mistake?
thank you everyone.

QUESTION
i'm trying to have a dynamic part of my form starting from a value i get from a http call (and later a select). The form is supposed to be required. That means every single input should be required. Of course, if the value i check on is not the "right" one, a part of the form should be hided and the inputs should be set as non-required (otherwise I can't save the data).
I already did it when the first value arrives (from the http, i just check the value and change the show/hide & required/not required part), but I can't do it on a select (the http value and the select are quite similar, but the select should be full dynamic). I just don't understand why, the mechanic should be exactly the same.
Here the html part:
This is the static value (from http call)

QUESTION
This is a little program in assembler executed in MPLAB with SIMULATOR for PIC16.
I don't understand why after the last NOP of the last three NOP the program return to the first of that group of NOP. In my mind after the three NOP the program is terminated and in fact there is END statement.
...ANSWER
Answered 2019-Feb-01 at 10:59I'd like to explain you the background about Jester's comment:
Background
You should keep in mind what Assembler language is and how a CPU and a memory works.
In the case of PIC16 devices, program memory is organized in 12- or 14-bit units. This means that the memory can store numbers with values in the range 0-4095 or 0-16383.
When a program is executed, the CPU will read the numbers from the memory and perform some action depending on the number read from the memory.
On the 12-bit variant, the number 451 for example causes the CPU to perform an addition.
Assembler is some special programming language, where each instruction (normally) corresponds to exactly one number in memory. The instruction ADDWF 3, 0
for example corresponds to the number 451 in memory.
The problems
- A CPU (normally) does not know some "END" instruction. Instead, a CPU will run endlessly.
Your program is 7 instructions long; this is 7 numbers in the program memory.
However, the size of the program memory of a PIC microcontroller is much more than 7 words.
Therefore there is some memory after the 3rd
NOP
instruction. This memory will contain numbers but you don't know which numbers it contains.The CPU will load the numbers that are stored there and execute them. If the number 451 is stored there, it cannot know if these numbers are there intentionally (because your program contains the instruction
ADDWF 3, 0
) or if the number is stored unintentionally because your program is shorter than the memory.
QUESTION
I started learning programming a few days ago, and here i am with my first problems. I'm learning something about batch, but there is something in my code that is wrong, can you help me with this?
Specifically, the "goto" command it's not a go to. i've tried to put it in a single line, but it's like the goto doesn't exist. how can i fix it?

Answered 2019-Jan-05 at 10:02Without more information I think your problem are not goto
commands but if
conditionals
Suppose the user types pikachu
on the first prompt. When the first if
is reached the batch's parser will replace the variable read operation %risp%
with the value inside the variable. So, your line

QUESTION
This routine is a windowed get/put-sprite emulation-routine. I'm Italian and I've not translated them. This routine is capable to flip-x-y the image before storing it in a 16 Byte aligned buffer. I omitted the precalculation routine for reasons of confidentiality. I learned thanks to the advice of Peter Cordes to fully use the LEA statement and is the first personal implementation of the ASSEMBLER 'BT' instruction:
...ANSWER
Answered 2018-Jan-07 at 04:07Never use the slow loop
instruction when optimizing for speed, except on AMD CPUs where it's not actually slow.
Avoid partial-register slowdowns by using movzx for byte loads. (lodsb is slower than movzx
+ inc esi
, so don't use it either). See http://agner.org/optimize/ for more x86 performance optimization stuff. (And also the links in the x86 tag wiki.)
Your 2nd function is just a blend based on the bytes not being a special transparent value. Use SSE2 to optimize it with pcmpeqb
and then blend with pand
/ pandn
+ por
. Or SSE4.1 pblendvb
.
SSSE3 pshufb
lets you more efficiently broadcast a byte to all positions.
Especially if you make a version with a fixed width, like 16, 24, or 32 pixels wide, you'd avoid needing much in the way of scalar cleanup code to handle odd widths. But anything wider than 16 should be doable with potentially-overlapping first/last unaligned vector stores.
And yes, making different versions of the function instead of passing integer flip / no-flip parameters is probably good, especially if you do the flipping with SSSE3 pshufb
(or multiple SSE2 shuffles, or even scalar bswap
). With pshufb
you could have an identity shuffle (that leaves a vector unchanged instead of reversing), but it would be more efficient to have a separate loop for the no-flip case that just don't use pshufb
at all.
QUESTION
I interited a sheet at work and there is no one who actually supports anything Excel related. My VBA is rather rusty and hence I hope that someone can help me out here.
I have the following code: It goes in error at line If mesi(mese) = "JAN" Then anno = Int(Right(oggi, 2)) + 1 Else anno = Int(Right(oggi, 2)) and i get Run-time error '9': Subscript out of range I have not changed anything and it used to work for a long time. I really appreciate any input
Many thanks
...ANSWER
Answered 2017-Nov-02 at 10:33Because, as @Skaterhaz stated, LBOUND(mesi)
equals 1 and (Int(Mid(12, 4, 2)) + 1)
will return 0 you will need to add one to your formula.
Dim mesi(1 To 12) As String
mese = (Int(Mid(oggi, 4, 2)) + 1) Mod 12 + 1
