Hello
What is wrong here ? :confused:
Code:
void CRDPDlg::OnBnClickedButton1()
{
        CFileDialog *cfileDlg = new CFileDialog(TRUE, NULL, NULL, OFN_ALLOWMULTISELECT, L"Text files (*.txt*)|*.txt*|");
        if (cfileDlg->DoModal() == IDOK){
                CString csPassFilePath(cfileDlg->GetPathName());
               
                int count = 0;
                std::string line;
                std::ifstream file(csPassFilePath);
                while (std::getline(file, line))
                {
                        listControl1.InsertItem(count,line.c_str());       
                        count++;
                }

        }
}
If i put listControl1.InsertItem(count,(LPCTSTR).c_str()); it prints weird characters

Code to measure CPU usage returns inconsistent results for overclocked CPU

August 14, 2015, 8:24 am

I have a somewhat strange behavior of the code I'm showing below. This code is called repeatedly to measure the current CPU usage in my application (the value measured for all CPU cores):

Code:
int getCPUUsage(void)
{
    //RETURN: = CPU Usage in percent [0 - 100], or
    //        = -1 if error
    int nRes = -1;

    FILETIME ftIdle, ftKrnl, ftUsr;
    if(GetSystemTimes(&ftIdle, &ftKrnl, &ftUsr))
    {
        static BOOL bUsedOnce = FALSE;
        static ULONGLONG uOldIdle = 0;
        static ULONGLONG uOldKrnl = 0;
        static ULONGLONG uOldUsr = 0;

        ULONGLONG uIdle = ((ULONGLONG)ftIdle.dwHighDateTime << 32) | ftIdle.dwLowDateTime;
        ULONGLONG uKrnl = ((ULONGLONG)ftKrnl.dwHighDateTime << 32) | ftKrnl.dwLowDateTime;
        ULONGLONG uUsr = ((ULONGLONG)ftUsr.dwHighDateTime << 32) | ftUsr.dwLowDateTime;

        if(bUsedOnce)
        {
            ULONGLONG uDiffIdle = uIdle - uOldIdle;
            ULONGLONG uDiffKrnl = uKrnl - uOldKrnl;
            ULONGLONG uDiffUsr = uUsr - uOldUsr;

            if(uDiffKrnl + uDiffUsr)
            {
                //Calculate percentage
                nRes = (int)((uDiffKrnl + uDiffUsr - uDiffIdle) * 100 / (uDiffKrnl + uDiffUsr));
            }
        }

        bUsedOnce = TRUE;
        uOldIdle = uIdle;
        uOldKrnl = uKrnl;
        uOldUsr = uUsr;
    }

    return nRes;
}
I tested it on several of my PCs and the code seems to return reliable results. Unfortunately, on one machine with overclocked CPU the code above seems to produce results twenty percent lower than the reading from the Task Manager (namely, the task manager would be showing 100% CPU utilization and my code would consistently return only 80%.)

CPU specifics on that "overclocked" machine:

Quote:
Intel(R) Core(TM) i7
Cores: 4
Logical CPUs: 8
NUMA nodes: 1
Does anyone have any idea why this code could get such faulty reading?

PS. Note that that CPU doesn't seem to produce any strange behavior, besides giving this inconsistent reading.

C++ Semaphore, limit 2 instances at the same time

Hello
I'm trying to make a loop create 10 threads but only 2 working threads at the same time, wait until one finish the job then start another thread but never exceed 2 at same time. I'm doing this with semaphores.
Code:
#include <iostream>
#include <Windows.h>

typedef struct structure1 { int threadnr; } structure1;

HANDLE ghSemaphore = CreateSemaphore(NULL, 2, 2, NULL);

DWORD WINAPI ThreadProc(LPVOID param)
{
        structure1 * t1 = (structure1 *)param;
        printf("Thread %i\n",t1->threadnr);
        Sleep(1000);
        return 0;
}

int main()
{
        for (int i = 0; i < 10; i++)
        {
                WaitForSingleObject(ghSemaphore, INFINITE);
                structure1 * t1 = new structure1;
                t1->threadnr = i;
                CreateThread(NULL, 0, ThreadProc, t1, NULL, NULL);
                ReleaseSemaphore(ghSemaphore, 1, 0);
        }
        system("PAUSE");
        return 0;
}
I set the semaphore max value at 2 but it start all threads at same time instead of only 2.
I tried to set WaitForSingleObject at the beginning of ThreadProc and ReleaseSemaphore at the end and it works but it will create all threads in buffer. I want to create just 2 at same time and wait for one to finish then start another one
Any idea ?
Thank you

Hi everyone! I am trying to write a function that compares the original word with its reversed. My main problem, and I cannot figure out why, I am getting always a "false" return in a boolean function that compares the two words. I have checked for spaces or strange word composition but it seems all ok. Here is my code:

Code:
int len(const char* s)
{
    int n = 0;
    while (*s != '\0')
    {
        ++n;
        ++s;
    }
    return n;
}

char* reverse_word(const char* c)
{
    int n = len(c);
    //    char* p2 = new char[n + 1];
    //    char* temp = &p2[n];
    char* p2 = new char[n + 1](); // *** default initialize
    char* temp = &p2[n - 1]; // ***
   
    while(*c != '\0') *temp-- = *c++;
   
    delete[] p2;
   
    return p2;
}

bool is_palindrome(const char* c, const char* p)
{
    if (p == c) return true;
    return false;
}


int main(int argc, const char * argv[])
{
    char ar[] = {"kayak"};
    char* p = &ar[0];
    char* p1 = nullptr;
    p1 = reverse_word(p);
    cout << p << " and " << p1 << " are ";
    if (!is_palindrome(p,p1)) cout << "not ";
    cout << "palindromes." << endl;
    keep_window_open();
    return 0;
}

Hello,
I have an MFC application and I have an issue where it does not disappear when minimized to the system tray.
It does correctly show an icon in the system tray when minimized, but it shows up just above the task bar on the left side of the screen. It does not display an icon in the taskbar, and I do not want an icon in the task bar.
How do I get the application to completely disappear from the screen?

Hi everyone,

I would like to learn how to Multithread in C++, however, I don't really know where to start.
As I understand it, Boost is the easiest to use to accomplish this?
Or should I be looking at something else?
Also, can anyone link me to a tutorial to get started?

64 bits application using Visual Basic 6 AciveX controls

August 19, 2015, 4:50 am

Hello

I have an application made with VC++ that can show a lot of dialogs. Those dialogs have been defined in an RC file and contains ActiveX controls made with Visual Basic 6.
My promen is the following one:
I have compiled the application in 64 bits, and when I launch the application and it is going to show a dialog, it fails. I think this is due to there is not 64 bits runtime for VB6.
What I want it is to generate an equivalent RC file to the RC file I have but replacing the controls made with VB6 with others made with VC++.
The obvious way is to edit the dialogs with Visual Studio C++ resource editor, and replace each control with its equivalent control. The problem is that I have a lot of dialogs (about 1000).
Is there a easy way to do this?

A possible way could be to generate an application that load the dialogs, and replace the controls during the execution, and then generate and RC file with the resultant dialogs. Something similar to what makes Visual Studio C++ resource editor.
I have tried to implement this solution, but I don't find the way to generate an RC file from a dialog loaded during the application execution.

Any help will be appreciated,
Best regards.

Converting 32-bit into 64

I have a sample code.

Code:
static DWORD CALLBACK StreamInCallback(DWORD dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb)
        {
        DWORD dwRead(0);

                if(SUCCEEDED(g_pTextFile->Read(pbBuff, cb, dwRead)))

                        return 0;
                }

                return 1;
        }
It works fine in 32-bit environment. But when I convert the whole project into 64-bit, I come across this error.

Hi to all,

Nowadays every skill has a certification, like MCITP, CCNA and so on. What about the programming? For example, apart from the universal degrees, is there any certification on C++ programming language? Someone that wants to be employed in a e.g., company, will need it so much to prove his ability, I think.

VC++6.0, Unicode, and ANSI strings

I have a VC++ 6.0 project that I'm thinking about rebuilding in Unicode. The bigget problem is that the data that I have to processes is 8-bit binary data that sometimes contains strings (e.g. "-12345X") that I have to detect.

I would like to have a class, something like an equivalent CStringA, that I can use on the 8-bit data when compiled with UNICODE/_UNICODE defined. I don't want to reinvent the wheel if someone has already done the heavy lifting. If not then I was thinking of wrapping the string function (i.e. strcat(), strcmp(), strcpy(), etc.) in a class.

Actually, I'm not sure it is worth the effort to rebuild in Unicode.

Anybody know of something I can beg, borrow, or steal?

Need opinion about proposal to set up a e-platform

Hi gurus,

how is it going? A friend and I are currently in the process of founding an enterprise in the e-commerce area. Therefore we need a creative and innovative webpage, that functions fast and looks unique.
We have asked a group of programmers and designers (they are called DMT from Peru, as we will operate in Peru as well) for an offer to design and develope this platform.
As my buddy and I lack IT knowledge we would like to ask professionals about their opinion considering their proposal as some features incl the time that would be necessary seem somehow sceptical.

The entire set-up/programming of the platform (front- & back-end) would take 52 days (8h per day we calculated)
+
design(25days) & mockups(20days) as step before.

The webstore, to give you a general impression how the page could finally appear, would be a mix of features of pinterest and jochen-schweizer.de considering the front- & backend.

We just want to give some examples of the feature list DMT proposed considering the platform caracteristics we prefer.

-page: feature (hours h necessary)

-registration page: send e-mail after registration process (8h backend)
-registration page: registration via facebook (12h backend 4h frontend)
-login page: field validation (4h backend 6h frontend)
-homepage: search function (6h backend 6h frontend)
-business profile: product list (10h backend 12h frontend)
-product profile: product information (6h backend 8h frontend)
-shopping cart page: payment selection (4h backend 2h frontend)
-...

There are many more features, but this should give you a general insight of what they are offering.

Considering all this information we hope, that there are some gurus that could give us their valuable opinion about the DMT offering. If it is realistic with regard to the features, example pages and hours you just have seen or if not.


We are looking forward hearing from you and appreciate every signle opinion.

Thank you and have a great day.

#include <windows.h>
#include "resources.h"

ID_MENU_MAIN MENU
BEGIN
POPUP "&File"
BEGIN
MENUITEM "&New...", CMD_FILE_NEW
MENUITEM "&Open...", CMD_FILE_OPEN
MENUITEM SEPARATOR
MENUITEM "E&xit", CMD_FILE_EXIT
END
END

And here is the corresponding resources.h file:
#define ID_MENU_MAIN 100

#define CMD_FILE_NEW 1001
#define CMD_FILE_OPEN 1002
#define CMD_FILE_EXIT 1003
anyway ...... nice to work about this!

Segmentation fault in C++ program

Hi,

I have a program in C/C++ that runs perfectly in my Windows 7, 32 bits.

But when I compile it in Linux, I get - only for some files reading - the "segmentation fault" error.

Below is the report of strace. Note: the overflow error of the file de431.eph does not happen with others smaller files. I don't know what might be causing this. The file is corrupted? Or is it too large?...

Code:
-bash-4.1$ strace ./swetest -p2 -j5000000 -ejplde431.eph
execve("./swetest", ["./swetest", "-p2", "-j5000000", "-ejplde431.eph"], [/* 28 vars */]) = 0

+++ killed by SIGSEGV +++
Segmentation fault
Might the FILE pointer be NULL for some reason?...

I would apreciate very much for some help.

Kind regards,

WinInet callback not called when the main thread sleeps

Hi, All,

I tried to use WinInet API to send a Http request and get back a page asynchronously, with the main thread waiting until the response is received in the callback function. However, it does not seem to work because the callback function is never invoked if the main thread sleeps. Anyone has some idea what is going on? If the main thread does not wait sleeping, it works fine.

Thanks at lot!
