i have an executable that is encrypted; it is made in Visual C++. decrypt it? what i must to look for? I have some kind of files (.req extention) that have the content encoded by password type.
View 2 RepliesI am to use this cipher in which the number x is encrypted
(a and c are known numbers)
Also, what will the decrypt function be? Actually, i need to find the decryption formula...below is the code i tried to test...
char x = 'a';

For my purpose all I need to know is drive's BitLocker encryption status by its DOS path. Something like this:

I was able to find the Win32_EncryptableVolume class that unfortunately comes with this caveat:
To use the Win32_EncryptableVolume methods, the following conditions must be met:
You must have administrator privileges.
How to do this without running as an administrator?

I have got to create a program that will gather input from the user and then encrypt & decrypt those characters.
I'm not very confident at coding so I'm sure many parts of my code are written poorly and not following the best practice so I have written a simple version of an algorithm where the program simply adds/subtracts a value of 2 to/from the ASCII values but I have discovered the use of the rand() and srand functions but I'm unsure how to go about using them within both my encrypt and decrypt function as a single value (static variable?).
Here is my code in its entirety at the moment.
#include <iostream >
#include <iomanip>
#include <cstdlib>
#include <ctime>
#include <string>
#include <cstring>
#include <fstream>
using namespace std;
char getMenuSelection (char m);
void encrypt (char key[]);
void decrypt (char code[]);
[code]....
This code currently doesn't execute due to ' undefined reference to 'encrypt(char*) '
Question
I am asking how to generate the random number and incorporate this into my encrypt and decrypt functions.
1. Would the use of a static or global variable make this work as is?
2. Would I need to create separate class files for both functions?
I have an application which needs to connect to a database. It runs in the background so there is no user input. I therefore need to store the connection string. I want to encrypt the connection details and then store the encrypted information. My thinking is I would read the encrypted details, from wherever I store them, unencrypt them and then connect to my database.
I've done a bit of reading on this and the SHA1CryptoServiceProvider method seems like an option but it appears that this cannot be unencrypted.
So how can I use this encrypted information?
Or is there another method?
How can decrypt the file that the program below encrypt?
// This program encrypts a file
#include<iostream>

int main() {
const int ENCRYPT=10; // amount to add to a chor
const int SIZE= 255; // array size

I have been working on some C++ code that doesn't seem to be going right. I'm wanting it to read a (three-digit) integer representing the value to be encrypted, a (one-digit) integer representing the encryption key, encrypt the value and print the encrypted value. The encrypting method used is that each digit in the given number is replaced by ((the sum of that digit plus key) modulo 10) then the first and last “encrypted” digits are swapped.
For example, if the number entered was 216 and the key given was 7, after applying the encryption procedure described the first digit (2) would become 9, the middle digit (1) would become 8 and the last digit (6) would become 3. The first and last encrypted digits are then swapped. The program displays the encrypted number: that is 389 in this case.
#include <iostream>
using namespace std;
int main() {
int isolateDigits();
int replaceDigits();
int swapDigit1withDigit3();

I'm very new to MFC & VisualC++. I'm using MSVS2010 Pro. I am trying to write/debug a simple form that saves and restores the content of some edit controls. It seems to work as expected, except the file saves only to the Project Folder, regardless of where I browse and select to save the file.
Code:
void CMFC_FileDialogDlg::OnBnClickedbtnsave() {
this->UpdateData();
CFile f;
//Kinda Correct, Works but still saves in Project Folder
BOOL b_OpenFileDialog = FALSE;//this doesn't act as bool in CFileDialog?

I need to develop an application in VC++ that will take .WAV files as an input and identify if there is a Gun shot in that wave file. WAVE file with gunshot must be having certain paramaters like frequency, bit rate etc which I don't know right now.

I created a new project in Qt Creator, the files included are the .Pro file, and the .Cpp file.
Qt does not recognize the headers I try to reference in the .Cpp file. I am pretty sure it's because of what I don't have in my .Pro file. What do I add to it?
.Cpp
Code:
#include <QApplication> ->No such File or Directory
#include <QPushButton> ->No such File or Directory
#include <QHBoxLayout> ->No such File or Directory
int main(int argc, char *argv[]) {
QApplication app(argc, argv);

Say, I have the "K: est del USB" folder.
Then I do the following:
Code:
SHFILEOPSTRUCT sfo = {0};
sfo.wFunc = FO_DELETE;
sfo.pFrom = L"K: est del USB";
sfo.fFlags = FOF_ALLOWUNDO |
[Code] ....
So when I run it, the SHFileOperation API shows this warning:
Are you sure you want to permanently delete this folder?
If the end-user clicks "No", SHFileOperation return 0x4c7, which I believe is ERROR_CANCELLED.
My question is, if I don't need any UI, how can I know that my file/folder will be permanently deleted vs. placed into the Recycle Bin?
I'm trying to build libglib using MSVC. libglib doesn't use dllexport - so to create usable DLLs it needs to generate a .DEF file. It does this by using a .symbols file. Here's a cut-down example:-
Code:
/* This file lists all exported symbols. It is used to generate the glib.def file used to control exports on Windows.*/
/* glib.symbols */
g_mkdir_with_parents
#ifdef G_OS_WIN32
g_file_get_contents_utf8
#endif
The following commands would produce the following files called glib.def
Code:
cl /EP glib.symbols > glib.def
produces this in glib.def:-
g_mkdir_with_parents
Code:
whereas this:-
cl /EP -DG_OS_WIN32 glib.symbols > glib.def
produces this in glib.def:-
g_mkdir_with_parents
g_file_get_contents_utf8
So this is a handy way of producing conditional .DEF files. Fortunately, this can all be built into a Visual Studio macro in my vsprops file - e.g.
Code:
<UserMacro
Name="GlibGenerateGlibDef"
Value="echo >"$(SolutionDir)glib.def" && cl /EP -DG_OS_WIN32 glib.symbols >>"$(SolutionDir)glib.def""
/>
Problem:- Although I can run the macro as a pre-build step (and it does produce conditional entries in the generated .DEF file) it DOESN'T produce the word EXPORTS at the top of the file. So the linker then fails to recognise it as a valid .DEF file.
How can I add that word EXPORTS to the top of the generated file? I tried just adding EXPORTS to the top of the symbols file but that didn't work. I also tried this variation on the macro:-
Code:
Name="GlibGenerateGlibDef"
Value="echo EXPORTS >"$(SolutionDir)glib.def" && cl /EP -DG_OS_WIN32 glib.symbols
But that didn't work either I feel sure there must be a way to do this.

I am developing a CFormView MFC app. When I go to click something on the menu, it takes awhile before the event happens. The project is build optimized in release mode. I have 3 additional threads and I thought they might be blocking the internal MFC framework stuff, but I use the Sleep() call in each thread to yield to the MFC main app.

When I have loaded a savefile with Serialize, is there some way of telling the name of the currently loaded savefile?
View 2 Replies View RelatedI have written code that saves a matrix to a utf-8 file. This code works just fine when invoked from a win32 console app, but if I attempt to use the exact same code by invoking it within a SDI Doc/View Serialize(CArchive& ar), if(ar.IsStoring), it fails, but in a somewhat unusual manner. Namely, the file shows up in the designated directory, but it is an empty file (0 bytes), and the 'Unable to open file' message is seen in Debug config. Note that both the win32 console app and the SDI app are both using a Unicode character set, however, only the SDI app uses the method inside a Serialize(CArchive& ar) method, whereas the win32 console app evokes the save method directly from within _tmain. Why this seemingly illogical disparity occurs.
Here's the template code I have used in innumerable applications to save matrices to a disk file.
Code:
namespace TNT {
// saves a TNT double matrix, discriminating between real and complex matrices by virtue of the respective file markers, 'MATCALC94R' and 'MATCALC94C'.
template <class T>
void SaveRealBMatrix(const Matrix<T> &M, string sfilename) {
_RPT0(0, "SaveRealBMatrix:
");
_RPT1(0, "sfilename =: |%s|
[Code] ....
Here's the code from the SDI document Serialize(CArchive& ar) that fails as described above. Note that m_M is a class member TNT::Matrix<double> m_M that has been verified to exist in the Serialize method.
Code:
void CMyWndDoc::Serialize(CArchive& ar) {
if (ar.IsStoring()) {
CString csFileName = ar.m_strFileName;
wstring ws = csFileName.GetBuffer(0);
string s(ws.begin(), ws.end());

I write a small application and using the following API to open the file:
hHandle = CreateFile(lpszFileName, GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
Then I pass the hHandle to a DLL exported function, in that function, I will call
DWORD dwFlags = 0;
ASSERT(GetHandleInformation(hFile,&dwFlags) != 0)
to check if the handle is valid. However, the assert fails. And I use GetLastError to get the error code 6, which means invalid handle.
What is the problem with my codes?
The program then asks the user for a search string, which may contain white space. The program should search the file for every occurrence of the search string. When the string is found, the line that contains it should be displayed in the following format
nnnnn:Line Contents
That is the line number of the line, 5 columns wide, right justified, followed by a colon, followed by the contents of the line.
And this is what I've got so far:
Code:
#include<iostream>
#include<fstream>
#include<string>
#include<iomanip>
using namespace std;
int main(int argc, char *argv[]) {
ifstream inFile;
string fileName,
[code]....
But this doesn't work. It prints everything in the file, not just the lines where the string is found.
I have experiences to localize a few MFC executable files, first create a resource dll file then add following code in InitInstance():
Code:

//Default Application Wizard code.
HINSTANCE hRes = NULL;
hRes= LoadLibrary("ResourceD.dll");
if(hRes)
AfxSetResourceHandle(hRes);
//Rest of wizard code
return CWinApp::InitInstance();
}

I have a project that has a few .asm files (assembly language code), I have the compiler/assembler set to create a list file for the assembly code and would like the debugger to use the .lst file for the source instead of the .asm files because in the .asm files the macros are not expanded like they are in the .lst files which makes debugging difficult sometimes.
