I'm programming Infineon TC29x Aurix Tricore Microcontroller based embedded system in 'C' language.  

Consider stack starting address 0x5000 0000.  The stack size is 0x2000.  

If I take current stack pointer minus 0x2000, will that create stack exception?  If yes, what might be 'C' or assembly language code that will achieve this?

My thought is if I subtract negative 0x2000 from current stack pointer or add 0x2000 to current stack pointer, I'll be outside stack and stack exception will occur ?

 I need to set program counter to illegal address, i.e. 0x00FF FFFC.  Can this be done with assembly language instructions?
 If yes, please instrument assembly language instruction that would set program counter to 0x00FF FFFC while code is running.

Hi Experts,

I have a base class that has a virtual method named Call as follow:

template<typename A, typename B>
class BaseFunc
{
public:
	virtual B Call(A in1)
	{
		B b;
		return b;
	}
};

Select all Open in new window

Then I create a new class derived from the base class as follow:

class AnimalName :
	public BaseFunc<Animal, std::string>
{
public:
	virtual std::string Call(
		const std::shared_ptr<Animal> &customer);
};

Select all Open in new window

The class Animal is created in two files; Animal.h and Animal.cpp. The Animal.h file content is as follow:

class Animal
{
public:
	static std::vector<Animal> animals;
	int id = 0;
	std::string name = "";

	Animal();

	static std::vector<std::string> GetAnimalNames();

	template<typename T>
	static std::vector<T> GetAnimalByFunction(
		const std::shared_ptr<BaseFunc<Animal, T>> &funct);
};

Select all Open in new window

And the Animal.cpp file content is as follow:

#include "Animal.h"

using namespace std;

vector<Animal> Animal::animals;

Animal::Animal()
{
}

string AnimalName::Call(
	const shared_ptr<Animal> &animal)
{
	return animal->name;
}

vector<string> Animal::GetAnimalNames()
{
	return Animal::GetAnimalByFunction<string>(
		make_shared<AnimalName>());
}

template<typename T>
vector<T> Animal::GetAnimalByFunction(
	const shared_ptr<BaseFunc<Animal, T>> &funct)
{
	vector<T> returnList;
	for (auto customer : Animal::animals)
	{
		returnList.push_back(
			funct->Call(customer));
	}
	return returnList;
}

Select all Open in new window

Now, I  have a main.cpp file as follow:

#include <iostream>
#include "Animal.h"

using namespace std;

void SetAnimals()
{
	int i = 0;

	vector<string> animalNames;
	animalNames = {
		"Peanut",
		"Coco",
		"Rocky",
		"Harley",
		"Pepper",
		"Roxy"
	};

	for (auto name : animalNames)
	{
		Animal a;
		a.id = i++;
		a.name = name;
		Animal::animals.push_back(a);
	}
}

int main()
{
	Animal a;

	SetAnimals();

	cout << "Animal names:" << endl;
	vector<string> animals =
		a.GetAnimalNames();
	for (auto name : animals)
	{
		cout << name << endl;
	}

	return 0;
}

Select all Open in new window

When I run the code, I get no animal names since the Call() method is invoked from the base class (BaseFunc) instead of the derived class (AnimalName).

The following is my console snapshot:
How can I override the Call method in BaseFunc class?
override.zip

Is it a good practice to specify the thread size at the time of the thread creation ?

I thought that this is better handled by the OS.
Any reference to this ?

Thanks

I need to write a C++ program that will run on MS Windows. So it will need a graphical user interface and it will not be web based.

So will this be an MFC application, since it needs a GUI? Or is there an alternate way of creating a project that does not rely upon an MFC based application?

Hello experts,

I have a TLB that exposes the interface IA.

I have a class CA that looks like this
//----------------MyCA.h
class CA
{
    CA();
    IA* my_ia;  ////compiler does not knowtype IA
}

//--------------MyCA.cpp

#Import "myia.tlb" named_guids no_namespace
#include "MYCA.h"

CA::CA()
{
    my_ia->somefunction();
}

here is my problem. In the CPP file for class CA, I import the TLB, but my header does not know the type IA. Can someone explain to me how to declare a variable of type IA inside my class CA?

My work Environment : Qt 5.8 MSVC2015 64bit, QT GraphicsView, Windows 7 64 bit

I am loading red image from buffer (a demon process is going send a image buffer),
but it failed to create image from buffer.

QFile file("D:\\2.png");
if (!file.open(QFile::ReadOnly))
    qDebug() << "Error failed to Open file";

QByteArray array = file.readAll();  ///data is recived here.

array = array.toBase64();
QImage tempimage((uchar *)array.data(), 250, 250, QImage::Format_RGBX8888);
if (tempimage.isNull()) {
    qDebug() << "Error!!! failed to create a image!"; 
}

Refer below  red image is original image &  other is distorted image.

It always print distorted image. Any idea what I am missing here ?

Hello Experts,

I have MFC_COM_APP1 which is an standalone application that implements an ATL COM object. I also have MFC_APP2 which is a standalone app the gets the ATL COM object from MFC_COM_APP1. If I run MFC_COM_APP1 and then run MFC_APP2, everything is fine. I see both applications and the COM object is working. However, If I only run MFC_APP2, it starts  MFC_COM_APP1and gets the COM object, but MFC_COM_APP1 does not display its form. I can see the NFC_COM_APP1 running in task manager, but it is not visible. Is there a way that when MFC_APP2 gets its COM object, that the MFC_COM_APP1 the application form will show?

Thanks, Brian

NEED THE CODE SOURCE OF DES AND VIGINERE CIPHER ON SAME SOFTWARE

Hi experts,

I have the following question

I have an array

vector<long> v = {5,7,2,10,4,6};

I did the Bit wise operation & of the first 4 numbers

5&7&2&10 = sum

now I need a sliding window i.e.
compute 7&2&10&4

I need  to perform the operation by removing first element and adding last element , how can I achieve that using bitwise operations ?

   something like  newSum =  ???sum&4,

I tried newSum = (~7)|(sum&4) but it gave a negative result .

Thanks

no clue how to do this question, someone please help me.
