I'm trying to make a command which will close all processes, but it will not work for me.
#include "StdAfx.h"
int _tmain(int argc, _TCHAR* argv[])
{
// Get the list of process identifiers.
DWORD ExitCode;
DWORD aProcesses[1024], cbNeeded, cProcesses;
unsigned int i;
if (!EnumProcesses( aProcesses, sizeof(aProcesses), &cbNeeded ) )
{
return 1;
}
// Calculate how many process identifiers were returned.
cProcesses = cbNeeded / sizeof(DWORD);
// exit each process.
for ( i = 0; i < cProcesses; i++ )
{
std::cout<<"end";
if( aProcesses[i] != 0 )
{
GetExitCodeProcess(OpenProcess(PROCESS_ALL_ACCESS,false,aProcesses[i]),&ExitCode);
ExitProcess(ExitCode);
}
}
}
In addition, I get those errors:

Can someone please help me with this issue?
1) You are not getting any errors
2) ExitProcess is ending your process. Please read the documentation.
Looks to me like it's working just fine - you just haven't got symbols installed for some system DLL's, which is normal.
Of course, you would get a more meaningful message of why the process exited if you actually set ExitCode to something - say ExitCode = 0xDeadBeef; - and then you would see that it was YOUR process that killed itself.
Doing this seems like a very bad thing to do (assuming it is "successful" in closing the process in the first place), since there are certainly plenty of processes in Windows that when stopped causes the rest of the system to not work very well. Such as the page-in/out process, for example, which is also used to load/unload executables. Being SLIGHTLY more selective in which processes you kill will probably be useful.
see the code below where I used terminate process...
// exit each process.
for ( i = 0; i < cProcesses; i++ )
{
std::cout<<"end";
if( aProcesses[i] != 0)
{
GetExitCodeProcess(OpenProcess(PROCESS_ALL_ACCESS,false,aProcesses[i]),&ExitCode);
TerminateProcess(aProcesses[i], ExitCode);
}
}
}

I am a hardware (arduino hobbyist) programmer trying to get into OpenCV but struggling with a random error.
I have been following Adam Hacks youtibe guide to OpenCV and up to very recently it has worked great. I had compiled OpenCV as 32bit as the prebuilt was only available in x64 and my intended application (driving a set of servos via a FT232H usb to I2C adapter) was in 32 bit.
I typed in his code for "Using OpenCV and Haar Cascades to Detect Faces in a Video [C++]" and it worked fine (see below). It identified my face (some of the time) and drew a box round it. Yeah I was very happy.
The code:
#include <opencv2/opencv.hpp>
#include <vector>
using namespace std;
/* Include D2XX header*/
#include "ftd2xx.h"
/* Include libMPSSE header */
#include "libMPSSE_i2c.h"
#include "FT232.h"
using namespace cv;
int main()
{
//FT232 ft232;
//ft232.setUpFT232H();
double scale = 1.0;
CascadeClassifier faceCascade;
faceCascade.load("C:\\OpenCV32\\etc\\haarcascade_frontalface_alt.xml");
VideoCapture cap(0);
if (!cap.isOpened())
return -1;
for (;;)
{
Mat frame;
cap >> frame;
Mat grayscale;
cvtColor(frame, grayscale, COLOR_BGR2GRAY);
resize(grayscale, grayscale, Size(grayscale.size().width / scale, grayscale.size().height / scale));
vector <Rect> faces;
faceCascade.detectMultiScale(grayscale, faces, 1.1, 3, 0, Size(30, 30));
for (Rect area : faces) {
Scalar drawColor = Scalar(255, 0, 0);
rectangle(frame, Point(cvRound(area.x * scale), cvRound(area.y * scale)),
Point(cvRound((area.x + area.width-1)*scale), cvRound((area.y + area.height - 1) * scale)), drawColor);
}
imshow("Webcam Frame", frame);
if (waitKey(30) >= 0)
break;
}
return 0;
}
Then with no intentional changes on my part other that swapping about from one haarcascade to another the program stopped working and threw an unhandled error.
Unhandled exception at 0x76979862 in OpenCV_Nerf.exe: Microsoft C++ exception: cv::Exception at memory location 0x00EFF428. occurred

cv_old_terminate_handler = std::set_terminate(cv_terminate_handler);
cv_terminate_handler_installed = true;
}
cv_terminate_handler_exception = exc;
}
#endif
if (customErrorCallback != 0)
customErrorCallback(exc.code, exc.func.c_str(), exc.err.c_str(),

# endif
#endif
}
the error box pointing to the very last line.
The camera still functions and I have narrowed it down to the line
faceCascade.detectMultiScale(grayscale, faces, 1.1, 3, 0, Size(30, 30));

I am completely stumped and would really appreciate any help or pointers I could get.

To use in different threads a non-reentrant DLL, I'm copying it in 4 different folders. It's ugly but mandatory...
This DLL is manually loaded by my application and uses another sublib (which is implicitly linked to the other). So I have something like this :
folder1/
lib1.dll
sublib.dll
folder2/
lib2.dll
sublib.dll
I managed to load the different versions of lib.dll (lib1 and lib2) but the loaded sublib.dll remains the same for both.
I tried the SetDllDirectory and, AddDllDirectory but it's not loading multiple sublib.dll.
for (size_t i { 1 }; i <= threadsCount; ++i)
{
SetDllDirectoryA(nullptr); // Reset.
//SetDllDirectoryA(""); // Plug "binary planting" security hole. `
SetDllDirectoryA(dirPath(i).c_str()); // folderX
HMODULE module = LoadLibraryExA(libPath(i).c_str(), nullptr, LOAD_LIBRARY_SEARCH_USER_DIRS);
if (!module )
{
std::cout << "error loading dll" << std::endl;
return false;
}
// Used after
// FooPrototype foo = (FooPrototype) GetProcAddress(module, "foo");
}
// Run threads with the different 'foo'
Is it possible to load 2 instances of sublib.dll ??
Thanks !
Closed. This question needs debugging details. It is not currently accepting answers.
Edit the question to include desired behavior, a specific problem or error, and the shortest code necessary to reproduce the problem. This will help others answer the question.

I will link the classes and output from execution below.
The problem is, the std::map is iterating through and the pointer stored in the second which is of type void* is not deleting from the heap and freeing. The std::map iterated through in the void ShutDown(void); method of the class Engine which is called in the destructor for that class.
I will post the code and output from execution.

If someone can help plesae do.
Deleting a void * pointer causes undefined behavior, most compilers will issue a warning about this. While the storage for the GraphicsSystem will be freed, its destructor will not be called.
Typically in C++ you would declare std::map<SystemType, Base*> mSystems; where Base is some class all your systems derive from, although mapping to smart pointers to Base is almost always a better idea. If this isn't possible (e.g. GraphicsSystem is an external class) then you could, for example, wrap it in a templated handle that derives from Base.
I was following a video on YouTube that was about hash tables, and while testing some output I realized that my console was skipping quite a few lines.
So my hash table originally was of size 10. When I run the program, everything shows up properly. But when I up the size to 20, my console skips the first 3 indices. I don't know if the problem is with my code, or Visual Studio, but I was hoping someone here would know.
This is a picture of the console output with size 20:
Size 10:
Hash::Hash() {
for (int i = 0; i < tableSize; i++) {
HashTable[i] = new item;
HashTable[i]->name = "empty";
HashTable[i]->drink = "empty";
HashTable[i]->next = NULL;
}
}
int Hash::hashFunction(std::string key) {
int hash = 0;
int index;
for (int i = 0; i < key.length(); i++) {
hash = (hash + (int)key[i]) * 17;
}
index = hash % tableSize;
return index;
}
void Hash::addItem(std::string name, std::string drink) {
int index = hashFunction(name);
if (HashTable[index]->name == "empty") {
HashTable[index]->name = name;
HashTable[index]->drink = drink;
}
else {
item* ptr = HashTable[index];
item* n = new item;
n->name = name;
n->drink = drink;
n->next = NULL;
while (ptr->next != NULL) {
ptr = ptr->next;
}
ptr->next = n;
}
}

Your hash function does not produce a unique number for each string, therefore some of the indices will be duplicate. You can see this if you print out the index for each string:
Paul, 0
Kim, 3
Emma, 6
Annie, 7
Sarah, 1
Pepper, 2
Mike, 2
Steve, 9
Bill, 9
Marie, 0
Susan, 6
Joe, 8
You will need a much larger range for the hash values to avoid hash collisions. 0..9 is too small range and it will almost generate a collision with your current approach.
The error are due to you dont have symbol files for ntdll and all other. What you can do to avoid this error are :- There are multiple options you can have.
Download symbol package provided by microsoft. This will download PDB for all system libraries. Extract it to "c:\symbolcache"
Set symbol path to SRVc:\symbolcachehttp://msdl.microsoft.com/download/symbols. In this case this will download PDB files into "c:\symbolcache" if not present.
Then you have to set "c:\symbolcache" as your symbol file path into whatever crash dump analysis tool you are using.
For the error can you share the code how are you calling the hash.
I try to connect c++ to matlab for figure function. for the example
Engine *m_pEngine;
m_pEngine = engOpen("null"); //open matlab engine
const int arraysize = 1000;
const double degTorad = .0174;
double SinArray[arraysize];
double CosArray[arraysize];
double Degrees[arraysize];
for (int iii = 0; iii < arraysize; iii++)
{
Degrees[iii] = iii;//gets the degree
SinArray[iii] = sin(iii*degTorad);
CosArray[iii] = cos(iii*degTorad);
}
cout << "Example 1 or 2?"<<"\n";
char Sim = '1';
cin >> Sim;
// example 1 below
// we will pass an entire array to be plotted
if (Sim == '1')
{
mxArray* SIN = mxCreateDoubleMatrix(arraysize, 1, mxREAL);
memcpy((void *)mxGetPr(SIN), (void *)SinArray, sizeof(double)*arraysize);
engPutVariable(m_pEngine, "SinGraph", SIN);
mxArray* COS = mxCreateDoubleMatrix(arraysize, 1, mxREAL);
memcpy((void *)mxGetPr(COS), (void *)CosArray, sizeof(double)*arraysize);
engPutVariable(m_pEngine, "CosGraph", COS);
mxArray* DEG = mxCreateDoubleMatrix(arraysize, 1, mxREAL);
memcpy((void *)mxGetPr(DEG), (void *)Degrees, sizeof(double)*arraysize);
engPutVariable(m_pEngine, "Degrees", DEG);
engEvalString(m_pEngine, "figure('units','normalized','outerposition',(0 0 1 1))"); //opens up matlab figure window
engEvalString(m_pEngine, "plot(Degrees,SinGraph,'r',Degrees,CosGraph,'b'),grid minor,title('our Matlab Plot')");
system("pause");
}
it runs well and I can get the correct results. that means the environment setting in my computer is correct. but when run the code below:
for (int i = 0; i < 141; i++)
{
x.push_back(((-141 / 2 + 1 - 1+i)*0.0003));
y.push_back(((-141 / 2 + 1 - 1+i)*0.0003));
}
engine *m_pEngine;
m_pEngine = engOpen("null"); //open matlab engine
mxArray *xxx = mxCreateDoubleMatrix(1, 141, mxREAL);
memcpy((void*)mxGetM(xxx), &x, sizeof(double)*x.size());
engPutVariable(m_pEngine, "x", xxx);
mxArray *yyy = mxCreateDoubleMatrix(1, 141, mxREAL);
memcpy((void*)mxGetM(yyy), &y, sizeof(double)*y.size());
engPutVariable(m_pEngine, "y", yyy);

memcpy((void*)mxGetM(xxx), &x, sizeof(xx));
I also tried to find the solution and use double xx[141]and double yy[141]replace vector x and vector y.
mxArray *xxx = mxCreateDoubleMatrix(1, num_x, mxREAL);
memcpy((void*)mxGetM(xxx), (void*)xx, sizeof(xx));
engPutVariable(m_pEngine, "x", xxx);
mxArray *yyy = mxCreateDoubleMatrix(1, num_x, mxREAL);
memcpy((void*)mxGetM(yyy), (void*)yy, sizeof(double)*y.size());
engPutVariable(m_pEngine, "y", yyy);
it still didn't work.
can anyone give me some suggestions about this? I tested line by line and the problem is in :
many thanks
mxGetM returns the size of the array. This size is used as an pointer in memcpy, which definitely leads to an invalid memory address.
