you should add on .h file : "use std::string " or class Record { public: void setPersonName(string); std::string getPersonName(); void setEmail(string); std::string getEmail(); void setTelephoneNumber(int); int getTelephoneNumber(); private: std::string personName; std::string email; int telephoneNumber; }

Thanks all friends . My code now run well . I have some error and how to fix . + fatal error C1189: #error : Building MFC application with /MD[d] (CRT dll version) requires MFC shared dll version.

Thank Maximilien, I didn't add this file . I will add this file. How to have any ways ? . if we don't add WinUtils.cpp and WinUtils.h inside new project. I know will dll , lib files we only use configure but we don't need add h and cpp file inside new project. Thanks Thong LT

Hi all . step 1: create new project on visual studio (project1.exe) step 2: create WinUtils.h and WinUtils.cpp on project1.exe and main1.cpp step 3 : add new project (project2.exe) and create main2.cpp Now I want to use WinUtils.h and WinUtils.cpp on project2.exe example //-----------------main2.cpp-------------------- #include "../utils/WinUtils.h" int main() { bool value = WinUtils::isWin64bit();/ function static return 0 ; } //-------------------------------------------- when i build code ,I saw error: + error LNK2001: unresolved external symbol "public: static int __cdecl WinUtils::Is64BitOS(void)" (?Is64BitOS@WinUtils@@SAHXZ) + fatal error LNK1120: 1 unresolved externals I make sure that isWin64bit() function is "public static" Please help me this problem .because my code has very much h and cpp files. Thanks Thong LT

Thank Albert and Richard . I am now reading "advanced-linux-programming" book and compile by gcc . Thanks Thong LT .

Hi ,all , I am now using Visual studio to build code on Windows OS . I am going to learn C on Fedora and write a small project about hooking file system but I don't know that compiler is good on Linux ( To inject dll file ). and I want to run code on other machines . I installed codeblocks but i don't make sure codebloks will help me . please help me . Thanks Thong LT

you can use codeblocks ,there is free of charge . http://www.codeblocks.org/downloads[^]

Hi Richard , I am writing code to hook process but when Process run in service i can not hook anything. I think I need to create service.exe in the same explorer.exe ,and then i will hook process which is running inside service by change createServices ,startService(), change path,etc . please see attached link. https://6u7mzg.dm1.livefilestore.com/y2ptrnPlJJujhKAudu3oz8U_ObqnYpSbaZgyoDmKZCKuglr8Zg3wu_HTk7jhUSmbw-jLmNb3d1PIaZeSqWEYQ3bw0aYYeW6arUGG59c57r9f1E/processExplorer.png?psid=1[^] Thanks Thong LT

Hi ,all, when PC starts up , smss.exe will create new session -service session (wininit.exe...) -User session (winlogon.exe ...) Now i want to create a new session inside MyService.exe . Can you share with me document or ebook ? wininit.exe ---------services.exe -------------svchost.exe -------------MyService.exe explorer.exe ------- chrome.exe wininit.exe ---------services.exe -------------svchost.exe -------------MyService.exe ----------------wininit.exe -------------------services.exe ------------------- -svchost.exe explorer.exe ------- chrome.exe Thanks Thong LT

Thank you a lot Thong LT

Hi All, when I build visual studio to create exe file .Then I run exe file ,It will have a process . and I continue to run exe file again . Therefore i will have two process for exe file . How to Create Single Process in C++ ? I think we can check process currently if process exist we exit new process. I try to use singleton but i can not create single process. Do you have any way ? Thanks Thong LT

Hi, Erudite , I graduated about one year so I don't have much experience about Win kernel .Thank you for helping me Thong Le Trung

Function NtCreateFile will call to change the name when we choose "save as" . Do I wonder content new file will have from ? . I think after create new file, it will read File from old file and then it will write data to new file.

I am sorry , I see error for you . I have a example , i hope this example will help you. What will be output of the following program?

#include
int main(){
float a=0.7;d
if(a<0.7){
printf("C");
}
else{
printf("C++");
}
return 0;
}

EXPLANATION Output: Turbo C++ 3.0: c Turbo C ++4.5: c Linux GCC: c Visual C++: c Explanation: 0.7 is double constant (Default). Its binary value is written in 64 bit. Binary value of 0.7 = (0.1011 0011 0011 0011 0011 0011 0011 0011 0011 0011 0011 ) Now here variable a is a floating point variable while 0.7 is double constant. So variable a will contain only 32 bit value i.e. a = 0.1011 0011 0011 0011 0011 0011 0011 0011 while 0.7 = 0.1011 0011 0011 0011 0011 0011 0011 0011 0011 0011 0011.... It is obvious a < 0.7

I have checked on visual studio 2010 , you can check again

#include
#include
using namespace std;

long double Harmonique(long double *t,int l)
{
long double s=0.0;
for(int i=0; i

Press any key to continue . . .

Thanks

I think you should check address of pointer and length of array

Hi,Erudite_Eric, Before I write data , I will hook NtWriteFile function and encrypt content file . Before I read data , I will hook NtReadFile function and decrypt content file to display file My code work well with "Notepad" , but crash with "Microsoft Word" when I choose "save as" I have checked .pdf file , .pdf file still works well . Thank you for your time. Thong Le Trung.

Hi ,all, When I open a .txt file .I think Notepad will call NtReadFile function . If I modify content .txt file and then I save txt file . I think Notepad will call Notepad will call NtWriteFile function . My question : When I open .txt file ,and next I choose "save as" . How many functions does Notepad call to be "save as" ? Will Data store on buffer or hard disc before we choose "save as "? How many functions does "Microsoft Word" call when we choose "save as" ? I think in the case "Microsoft Word" will use memory mapped file to be " save as" Thanks Thong Le Trung
