I want to determine the existing drives in my PC viaa program. I was able to do that by using FindFirstFile, if it does not able to find any single file on the path (e.g "c:\\*"), then it means that the drive does not exist, and it worked out well but the problem is that I don't know if the drive detected is a CD drive, a USB, etc. Do you guys know how will I going to determine the Drive specifically if its a normal hard disk or a CD, DVD, USB, etc? Thanx

Guys, I REALLY need help. My program works but it does not give me the outcome I am looking for. Let's say I have this input:
110.0 12.4 -10.0 16.1 78.9 123.0 -2.0 59.3 66.5 658.45 -1.1
My program should sort these numbers up to the negative and than print, than it should keep on reading, sorting and when it hits negative again, it should print again. Like this:
110.0 12.4
123.0 78.9 16.1
658.45 66.5 59.3
My problem is that my program sorts ALL the numbers and gives an output like this
12.4 16.1 59.3 66.5 78.9
and so on whithout breaking on the negative. Can somebody look at my code and tell me what do I do wrong? Your help is greatly appreciated!!!
#include <iostream>
#include <cstdlib>
#include <stdlib.h>
using namespace std;
void bubbleSort(double array[], int size);
double *getDouble(int & numbersRead)
{
int arraySize = 0;
double inputVal;
double *array = NULL; // Initializing to NULL pointer
numbersRead = 0;
cout << "Please, enter any number of integers: ";
cin >> inputVal;
while(inputVal != -1.1)
{
if(numbersRead == arraySize)
{
double *original = array;
array = new double [arraySize * 2 + 1];
for(int i = 0; i < arraySize; i++)
array[i] = original[i];
delete [] original; // Safe if original is NULL
arraySize = arraySize * 2 + 1;
}
array[numbersRead++] = inputVal;
cin >> inputVal;
}
return array;
}
int main ( )
{
double *array;
int size;
array = getDouble(size);
for (int j = 0; j < size; j++)
{
if (array[j] > 0)
bubbleSort(array, size);
cout << array[j] << " ";
cout << endl;
}
delete [] array;
return 0;
}//end of main
void bubbleSort(double array[], int size)
{
int last = size - 2;
int isChanged = 1;
while(last >= 0 && isChanged)
{
isChanged = 0;
for(int k = 0; k <= last; k++)
if(array[k] < array[k+1])
{
double temp;
temp = array[k];
array[k] = array[k+1];
array[k+1] = temp;
isChanged = 1;
}
last--;
}
}

Hi,
maybe this one works:
void sort(double* Array, int Begin, int End)
{
for(int i = Begin; i < (End - 1); i++)
{
int m = i;
for(int j = (i + 1); j < End; j++)
{
if (Array[m] < Array[j])
{
m = j;
}
}
double d = Array[i];
Array[i] = Array[m];
Array[m] = d;
}
}
void show(double* Array, int Begin, int End)
{
for(int i = Begin; i < End; i++)
{
cout << Array[i] << " ";
}
cout << endl;
}
int main(int argc, char** argv)
{
const int size = 11;
double array[size];
array[0] = 110.0;
array[1] = 12.4;
array[2] = -10.0;
array[3] = 16.1;
array[4] = 78.9;
array[5] = 123.0;
array[6] = -2.0;
array[7] = 59.3;
array[8] = 66.5;
array[9] = 658.45;
array[10] = -1.1;
int start = 0;
for(int i = 0; i < size; i++)
{
if (array[i] < 0)
{
sort(array, start, i);
show(array, start, i);
start = (i + 1);
}
}
return 0;
}

If the array ends with a positive number:
int main(int argc, char** argv)
{
const int size = 13;
double array[size];
array[0] = 110.0;
array[1] = 12.4;
array[2] = -10.0;
array[3] = 16.1;
array[4] = 78.9;
array[5] = 123.0;
array[6] = -2.0;
array[7] = 59.3;
array[8] = 66.5;
array[9] = 658.45;
array[10] = -1.1;
array[11] = 100.0;
array[12] = 200.0;
int start = 0;
for(int i = 0; i < size; i++)
{
if (array[i] < 0)
{
sort(array, start, i);
show(array, start, i);
start = (i + 1);
}
}
if (start < i)
{
sort(array, start, i);
show(array, start, i);
}
return 0;
}

So how does it work if it does not give you the outcome you are looking for?

This condition may never evaluate to true. It's best not to test floating-point numbers for equality to a constant value. A better solution would be something like:
while (inputVal > 0.0)

If you read through the program you will see that I can not use
while (input > 0.0)
because you will get an infinite loop. How would my program will end the user's input from the keyboard?!
A line of code
while (inputVal != -1.1)
is keeping track of when the user is finished to enter numbers.
|
|
|
|
|
double number;
while(cin >> number)
{
cout << number << endl;
}
Any input that is no number will terminate this loop.

Infinite loops are very easy to work around. Trying to do something with floating-point numbers that they were not designed to do is a lot more critical.

Hi. How can i include an image on top of a dialog? Thanks.

Hi,
you could add a CStatic control to your dialog.

There is a special picture control you can add just like a static control.
Don't try it, just do it!

I am using the Win32 API to create an application to assist in making a custom .font file format for a game I am making. It is a SDI application. Although my question may seem simple, I was unable to find anyway of doing it, or maybe searching for the wrong thing, I don't know. Anyway, I want to be able to programatically change the size of the window, at run time. I have a title bar, menu, and borders, and I don't want to have them included when resizing. By that I mean, for example, I wanted to resize the window to 500 pixels by 500 pixels, the white space in between (not including) the menu and borders would be 500 pixels by 500 pixels. Also, I want to disable the user from resizing the application. Anyone have any ideas?
Thank you

What if you need to search for files that attach themselves on other file (just like what virus does), will CRC do you something good or you need to do something else?

Hi,

If you want to create linda virus scanner it does not!
You can only check if a file has changed since the last scan, but not if one file is able to change another one!
Don't try it, just do it!

Does the file searcher in windows' start menu uses CRC? My guess is it doesn't. It only uses FindFirstFile.

Hi,
This question is going to make me sound really dumb, but here goes: What is the easiest way to create and IStream from on a file with a given path?
Joel Holdsworth
|
|
|
|

If using MFC - you can try CArchiveStream declared in afxpriv2.h (create CFile, create CArchive on it and then CArchiveStream). But the implementation is not full. One of the major methods, Stat, is not implemented.
Otherwise, AFAIK, you have to implement it manually...
BTW, the question is very interesting. If anyone knows whether a system contains a ready-to-use function that returns IStream* on a file path, please tell!
One always gets the deserved.
