Dialog based application : updating

Frandy · #1 24-Sep-2004, 08:32

Hello:
I've created a dialog for a math C program, the output of which is stored in an array as double variables.
The associated custom dialog that pops when pressing a button on the main dialog should display the output let's say as a string list.
What should I do to get that display ?
Thanks in advance for your help.

You can make a char[] out of a float like this:

CPP / C++ / C Code:

#include "conio.h"
#include "iostream.h"
#include "string.h"
#include "stdio.h"


char s[20];

int main(int argc, char* argv[])
{
	double a[20];
	
	for ( int i = 0; i < 20; i++ )
	{
		a[i] = (double) i + i;
	}
// char[] way
	sprintf(s, "%f", a[4]);
	cout << s << endl;
	getch();

	return 0;
}

Or, if you would rather use CStrings (as I do):

CPP / C++ / C Code:

// CString way
	CString cs;
	cs.Format("%f", a[4]);
	AfxMessageBox(cs);

You can display those in a list, or any kind of edit box you please...

Best regards,
Luci
