Visual C++ :: Unable To Find Setting For Exception Handling In MFC
Jan 24, 2013
My MDI Project(VC++2010 Professional) is unable to catch errors ,though I return ,try catch block. So I developed simple dialog based application .Placed one button on Dialog and on its click written following code
Collapse | Copy Code
void CMFCExecDlg::OnBnClickedButton1() {
try {
int j = 0;
int i = 10/j;
}
catch(CException * e) {
MessageBox(_T("Hello"),_T(""),MB_OK);
}
}
But still program control does not come in catch block it simply gives error. I tried all child classes of CException but no use.I think there will be some setting in Visual Studio. How to handle exceptions

I tried to write a little bit of code to set all bits within a signed int with exception to the MSB, yielding the greatest max positive value. The odd part is that it works for shorts ints, and longs, which are 2, 4 and 4 bytes respectively, however long longs, with a size of 8 bytes, simply yields -1, which would indicate that it failed to clear the MSB. Heres the little segment in question:
template<typename T>
T getMax() {
return my::numerics<T>::is_signed ?
~0 ^ (1 << ((sizeof(T)*8)-1) ):
~0;
}
my::numerics is just an exercise- its thoroughly tested and I'm certain thats not the issue.
For shorts, ints, longs, this yields the maximum value. However, when I use it on long longs, the output is 0xFFFFFFFFFFFFFFFF, i.e. ~0. Obviously this means the maximum value for unsigned long longs, but -1 for signed long longs.

I know how exception handling works, but how should I actually use it in action? Let's say I have something like this:
Class X
{
public:
X();
//Pre-condition: example can't be 3.
void number(int example);
[code]......
If I know that the exception can only happen at the beginning of the function, is it okay to catch it right away?

write a program as described below: program that reads in two integers (age, social security number). You should write functions that throw an out-of-range exception forage (no negative numbers)SSN (must be a 9-digit integer) My code is written below:
#include "std_lib_facilities_4.h"
int main(){
int age = 0;
int ssn = 0;

It is advisable not to throw the exception from destructor. Because if exception happens stack unwinding happens. suppose the destructor again throws the exception then on part of first exception again one exception is thrown and exceptions can not be handled at same time. This is what i read from stack over flow.

I'm out of track how to realize one point in exercise condition wording :
Give the OutOfBoundsException class a constructor with an int as argument that indicates the erroneous array index and store it in a data member.
How should I change the code below .
Code:
//array.h
#ifndef Array_H
#define Array_H
#include "point.h"
#include <string>
using namespace std;
class Array {
private:
Point* m_data; // Dynamic Array of Point pointers

I have a date class and i overloaded operator >> to accept input in dd/mm/yyyy format. if i enter the wrong date format my program will crash. How do i do exception handling for this? How should i do the try part? and for catch, I'll just catch a date class variable?
Code:
void operator >> (istream &is, clsDate &date) {
string inputDate;
is >> inputDate;
int mm = stringToNumber(inputDate.substr(3,2)); // read 2 characters from character number 3 start
int dd = stringToNumber(inputDate.substr(0,2)); // read 2 characters from character number 0 start
int yy = stringToNumber(inputDate.substr(6,4)); // read 4 characters from character number 6 start

writing a program that requires exception handling. if an error occurs, i what the program to go back to the begging of the loop. i tried using break but that just makes the program crash when it receives a bad input. how do i do this? this is what i have so far (this part of the program any ways)
while (! quit)
{
// Output phone book menu
cout << endl

I'm having some significant trouble with an assignment to create a postfix calculator that simulates the dc calculator function in linux. I have attached the handout with project instructions, but my main problem at the moment lies with parsing through the string input and adding the numbers into a stack of ints.
Project #2.pdf (47.78K)
Here's a brief summary of the methods used in the switch statement:
OPERATORS AND COMMMAND INPUTS
+ : Pops two values off the stack, adds them, and pushes the result.
- : Pops two values, subtracts the first one popped from the second one popped, and pushes the result.
* : Pops two values, multiplies them, and pushes the result.
/ : Pops two values, divides the second one popped from the first one popped, and pushes the result.
% : Pops two values, computes the remainder of the division that the / command would do, and pushes that.
Commands
p - Prints the value on the top of the stack, without altering the stack. A newline is printed after the value.
f - Prints the entire contents of the stack without altering anything. A newline is printed after each value
n - Prints the value on the top of the stack, pops it off, and does not print a newline after.
c - Clears the stack, rendering it empty.
d - Duplicates the value on the top of the stack, pushing another copy of it. Thus "4d*p" computes 4 squared and prints it.
r - Reverses the order of (swaps) the top two values on the stack.
Exception handling also needs to be added to account for division by zero and and invalid operator.
Right now my biggest problem is that I keep getting the following strange output where a 0 is automatically added to the stack when I call a function or operator. I realize this is probably because of the lines I have placed outside of the for loop that read
//END FOR LOOP
int num = atoi(operands.c_str());
myStack.push(num);
operands = "";
cout << num << " added." << endl;
But when I tried putting these statements INSIDE the for loop, I just get more errors. I've been working on this for a number of hours but I can't figure out my issue. I've also attached an image of my current output.
#include <iostream>
#include <cctype>
#include <string>
#include <cstdlib>
using namespace std;
#include "stack.h"
bool isOperator(const char& input );

The code is compiled.
If I do loops for push and pop fucntions in main.cpp the same size as Stoke everything is working properly
If loops are larger than the Stack size that goes here is a picture in the console (see screen print)
Code:
//
//(---.Array_hpp---)
//
#ifndef Array_HPP// Preprocessor gates
#define Array_HPP
#include <sstream>
#include <iostream>
#include <exception>
template <class Type>//Remove the "=double" default parameter.

How to incorporate exception handling code into my existing calcMortgage code. While I was researching exception handling, I thought "what would happen with my current code if someone input the principal with a comma in it?". Typically people write two hundred thousand like so.... 200,000. While experimenting with my original code, I remembered reading in my research that someone had done their calcMortgage with the output prompt "DO NOT USE COMMAS". So, when checking to see if my code would run, I did not use commas.
Well, guess what...using a comma in the principal causes an error with a negative numerical output. lol PERFECT!!!! Obviously, the easy thing to do would be to put output instructions in the code telling the user NOT to use commas, but the assignment requires me to use exception handling. The code itself works, but the calculation produces a negative monthly payment.
How would I insert exception handling code into my current code to correct this problem??
#include <iostream>
#include <cstdlib>
#include <cmath>
using namespace std;
struct calcMortgage {
double Principal, numYears, IntRate, monthlyPayments;};
int main(){
[Code]...
would I use a try or a throw??

I'm new in programming, and trying to write a code in C. The requirement is following - to write a text, and to find frequency of 1 chosen character in it. The main thing is that program should check user input (for example, I want to check if user entered "char" --> then correct, or if entered "int" --> not correct). But the program still doesn't check. So I have:
Code:
#include <stdio.h>
int main(){
char c[1000], ch;
char i, count=0;
printf("Enter a text: ");
gets(c);
[Code] ....
Am I on my right way using if/else?

I am trying to find the distance between two void pointers, so I can follow this distance to a certain pointer in a vector when given only the previous element in that vector.
int distance = (char*) prev - (char*) first;
next = (char*) cv->elems + cv->elemsz + distance;
Basically, prev and first are void pointers. I am trying to cast them into a char, subtract the first element in the vector from the previous one, and then use this distance to determine what the next element in the vector is. However, it is not working. I am not sure how to do this. To complicate matters, prev is a const void *.

Why would the following line of code cause an exception and how can I fix it? This is with Visual Studio 2013 and it is set to use "Multibyte Character Set". This is a very old program that I was updating.
Code: thepath = dadir + "*.csv";
Both dadir and thepath are type CString.
Prior to this line dadir looks fine when I look at it in the debugger but when I reach this line of code I get
First-chance exception at 0x0FA08EE1 (mfc120d.dll) in GAQUtilities2014.exe: 0xC0000005: Access violation reading location 0xFEFEFFC6.

I have a MFC dialog project, I move all the icons including the IDR_MAINFRAME icon into a resource-only DLL, so there is no icon embedded in the executable file. In the dialog initialization, the dialog loads the icons using LoadIcon(hResdll, MAKEINTRESOURCE(IDI_MYICON))). The icons shows correctly on the dialog.
But in the Windows Explorer, the icon of the .exe file is not the icon of IDR_MAINFRAME, I check the resource file in the resource-only dll project, the ID number of the IDR_MAINFRAME is the lowest one of all icon ID numbers. I also try
Code:
SetClassLongPtr(m_hWnd, GCLP_HICON, (LONG)LoadIcon(hResdll, MAKEINTRESOURCE(IDR_MAINFRAME)));
But it doesn't work. The IDR_MAINFRAME icon doesn't show in the Explorer window, the system provides a default icon for the .exe file.

I have a MFC app developed in VS 6.0
User can open multiple dialogs in this app. Is there a way of keeping track of how many dialogs are open at a given time?
Also, is there a way of getting the handle to each dialog from a central location?
Because the dialogs are opened from different parts of the app, i.e., different files its hard to keep track of all dialogs.

pSliderCtrl->SetRange(1, 100); // ok no problems
Now, how to "move" btw. how to redraw the position of the slider thumb programmaticaliy with c++? Need to send some message, if yes what message i need to send to slider control to move (reposition) the slider thumb?
I try with
// first:
::SendMessage(pSlider->m_hWnd, WM_NOTIFY, TRBN_THUMBPOSCHANGING, 0);
// then with:

I believe I set up everything correctly. I linked the library folder, the includes, and included the libraries needed. It still comes up with an error that it can't find the functions or something like that.
The error:
Do I need to include the DLL some way? I tried adding it to the build directory and the EXE directory, but it did not work. My code is just a small test.
#include <GLFW/glfw3.h>

I am trying to make an add-on to IE. This add-on doesn't have any tool bar or any UI.
I am just taking the details of currently loaded HTML page. Basically it is for manipulating one dialog box. I want to get access to the DOM COM interfaces of the dialog box.
Since it doesn't have any button I didn't impliment IOleCommandTarget. I implemented only IObjectWithSIte.
My RGS file contain following in addition to my COM related entries
HKLM
{
NoRemove SOFTWARE
{
NoRemove Microsoft
{
[Code]...
But I couldn't see my add-on working or even not loading to IE.
