i'm using visual studio but i have problem with the code project i'm learning le function
thanks

Do you mean how to use Visual Studio? Which language are you using (VC++, VC#, ...)?
We can speak italian if you prefer...
|
|
|
|
|
se parli in taliano va meglio.con visual studio creo i project ma non riesco a trasformarli con il comando compile
|
|
|
|
|
Il comando Compile non è quello di cui hai bisogno: esso esegue soltanto la compilazione del file che attualmente hai aperto nell'editor (se guardi nella cartella dei files intermedi troverai qualcosa tipo nomefile.obj).
Per ottenere il file eseguibile finale devi usare il comando Build oppure Rebuild.
|
|
|
|
|
il problema è che debbo imparare i codici da inserire nel file cercando su internet c'è di tutto
ma non so usare i comandi come include o le funzioni numeriche

In questo modo però rischi di diventare vecchio prima di aver imparato! Prova a partire da qui:

Non li ho guardati tutti, ma sono in italiano e dovrebbero darti una panoramica di quello che serve per iniziare.

veramente vorrei imparare senza manuali tu dici che è possibile?

Per "imparare" servono sia teoria che pratica.
La sola teoria o la sola pratica sono ... masturbazioni. Possono essere divertenti, ma non producono nulla che duri a lungo.
L'"esperienza" si fa passando dall'una all'altra alternativamente su cose via via più complesse.
Se non hai tempo (ne passione) per questo, cambia mestiere.
Da quanto vedo, il modo assolutamente approssimativo con cui esprimi i concetti anche basilari ti sta già creando problemi di comunicazione ... chi ti deve rispondere fatica a cogliere di quale argomento parli. Non perché non lo conosci, ma perché usi una "lingua" tutta tua. Fatta sulla sola "pratica" che solo tu conosci.
Se insisti moooolto a lungo potrai anche diventare un grande esperto, che però non riuscirà mai a "vendere" nulla di ciò che produce e che difficilmente troverà compagni di avventura con cui lavorare su cose più complesse.
Non puoi imparare senza "studiare" ciò che altri hanno già "imparato" prima di te.

Yeah great idea; now all the non-Italian speakers have no way of figuring out whether your suggestions are useful or not. 
It's time for a new signature.

I'm very sorry Richard  You are absolutely right... I tought to better help the enquirer, but I forgot the others... I try to fix my mistake:
albertodiprima said that he isn't able to produce an exe using the Compile command in Visual Studio: I told him not to use the Compile command, but Build or Rebuild.
By the comment of albertodiprima I supposed that he has lacks in basic concepts about C/C++ and development tools (he said that doesn't know how to use the #include directive and similar), then I suggested him to buy a book and a website where are available a number of tutorials on C/C++ and Visual Studio.
Now he say that doesn't like to learn using books nor tutorials and he'd like to learn completely by himself by trying and searching the internet, and he is asking what I think about...

Thanks for the translation. There is no problem with communicating with someone in your native language, but you should do it by direct person to person email and not in the forums.

Don't underestimate the italian to english Google translators. 
50% of Italian techincal text is made by inglish words, and 30% of italian neologism taken from english!
It is vice-versa that is a nightmare (when you got the translation even of what shouldn't)
I often have to back-traslate italian to english to understand what the italian text really means!

I've run that code on 2 core cpu
...
for (i = 0; i < N * N; i++)
vec3[i] = vec1[i] * vec2[i];
...
#pragma omp parallel for
for (i = 0; i < N * N; i++)
vec3[i] = vec1[i] * vec2[i];
...
Even if I run it by setting explicitly omp_set_num_threads(1) to use just one thread it runs about 1.66 times faster. Using 2 threads the speed up is 2 times.
I've checked with omp_get_thread_num() how many threads were running.
What is the reason for single thread OpenMP to outperform ordinary for loop?

Hi,
Well there many possibilities.
Even using the ordinary loop, you can get different perfromance results between writing :
for (i = 0; i < N * N; i++)
vec3[i] = vec1[i] * vec2[i];
and writing this :
for (i = 0; i < N * N; i+=2) {
vec3[i] = vec1[i] * vec2[i];
vec3[i+1] = vec1[i+1] * vec2[i+1];
}
So one hypothesis would be that the OpenMP look implementation knows the better way how to do the transfer of data.
The number of 1.66 should tell something. No doubt !
Let me guess, 1.66 is 5/3
If the process involves the repetition of N tasks, with each task lasting T duration then the new gain is 3/5 T
meaning we got rid of 2/5
There is a constant task, and that is the multiplication. It woud be too coincidential to get that 66 number if not the constant part is about the ..
Emmm I will think about this in the bus.
Good day.
1.66 means means

i suspect the OpenMP optimizer has compiled your loop to SSE instructions, and therefore, you're doing two or four (or eight?) of those multiplications at a time.
look at the assembly, to verify.

I made some tests on my computer and I had a look to the assembler code produced by the compiler: it seems that the non-parallelized version of the loop use the mul opcode (then using the FPU stack), and the parallelized version use the mulsd opcode (then using SSE2). In both cases only a single multiplication is performed at a time, but using the FPU stack requires too much work to move the operands from memory to the stack and then the result from the stack to memory.
I hope this could help! 
Cheers,
Sauro

Hi,
I want the following view on the CListCtrl, report view.
|Column A|Column B|Column C|Column D|
|Bitmap1 | Bitmap2 | Bitmap3 | Text |
Bitmap images in the three columns, and a text in the third column.
I am so confused about how to implement it.
I tried with this Neat Stuff to Do in List Controls Using Custom Draw[^] sample using custom draw, but could display bitmap in 1st column only.
I would like the row height(=Height of bitmap) to be larger then the default row height.

Hi All,
As we know integer has value limitation's(ex +_32767) depends upon bit range(ex 32 bit,16 bit).
i'm working with an integer variable which gets input from text box(designed as Activex control).
my condition is if the user enters the value in text box greater than 10 means it should show the error symbol otherwise correct symbol.
so the problem is if i enter the value 10 to 36767 means it shows alert symbol. if it is above 32767 means it shows correct symbol.
How can i solve this integer value Rotation Problem?

It is (usually) -32768..32767 for signed shorts.

Do you mean wrap-around problem?
It depends on how much control you have on the input. For instance, if you can read the input string, then a length > 2 is an error condition.

That's simply silly and the user must be punished for...

Can't you simply use unsigned values ?

You are going to have to add an event handler for OnChange so that you check the input on edit.
