You have the Source Code in Hand!

Why not load it in your debugger and find out Where and Why it does not work.
I am afraid that the reality is that writing code involves debugging. actually, it is an integral part of it. of all the members on this forum, I guess that few of the experts regularly write code that always compiles. Fewer write code that immediately performs as advertised. Those that do are continually worried about what their code 'might' do under adverse conditions.

Unfortunately Debugging is part and parcel of writing code. This forum is NOT about doing the Debugging for you.

Is this better? I kinda figured out how to use the function, but now I think thats where my problem lies. When i choose say 35 as the first value inputted, and then stop the loop, i dont get a correct celsius value but a number like 14.2323.2323. Here is my updated code, thanks.

[code]
// Computer Lab test.cpp : Defines the entry point for the console application.
//

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

using namespace std;

// call this function to convert fahrenheit values into celsius (function name is CheckCent)
double CheckCent(double c)
{
if (c <= 30) return c;
c=c-32/1.8;
return c;
}

// main function
int _tmain(int argc, _TCHAR* argv[])
{
double myarray[51];
//double i;
int flag;
flag=1;
int i;
for(i = 0; i < 51 && flag == 1; i++)
{ // Loop to enter temperatures - pressing 1 continues, pressing 0 stops //
cout << "Enter Temperature Reading:";
cin >>myarray[i];
cout << "Enter 1 to input more values, 0 to stop";
cin >>flag;
}// End for
cout << "Number of elements in the array is: " << i;
cout <<"\n";

for(int j=0;j<=i;j++)
{
myarray[j]=CheckCent(myarray[j]);
cout << myarray[0];
}
return 0;
}

Here's my function :

<br />
double FahrenheitToCelsius( double reading )<br />
{<br />
   return ( reading - 32.0 ) / 1.8;<br />
}<br />

That's what I would have written too, but, This member appears not to know how to debug, or, that debugging is an integral part of code developmpent.

Just for once, and Never Again, and just because it reminds me of My studend days (1974, We had no internet those days, it had not been invented yet)

I give a hint.
A Fibonacii series starts with a 0 and a 1.
You should know how it Generates from there.
I Write it in 'C' You have to translate it to CPP all by yourself.

void FibGenAndPrint(){
static int FibSer[502]={0,1};
int i;
// Generate The list
for(i=1;i<500;i++)FibSer[i+1]=FibSer[i-1]+FibSer[i];
// Print the List
for(i=0;i<500;i++)printf("%i\n",FebSer[i]);
}

There's no error messages there - everything indicates the program ran succesfully.

Why your image doesn't display is another thing....

Help with MFC controls

I am rather new to MFC and am currently trying to BS my way through it, but I am having a few problems.

First, I am wanting to create a control that is similar to what you would find in Windows Task Manager (multi-column, vertical scrolling, selectable and sortable) but I can't seem to find the control that will work. Is this a modified ListBox or is it a custom control. I tried searching for it but don't really know what I'm looking for.

Second, why doesn't my dialog use the theme of Windows. It does in the resource editor but not when run. I've tried googleing but again, I'm not really sure where I should be looking.

Any help is appreciated.
Thanks,
Dustin

That's a List-View control: List-View Control Reference[^]

Using Spy++, you'll note that it is a window belonging to the "SysListView32" class.
