win32 and user defined classes

[paulf]

#include <windows.h>
#include "resource.h"
and MS visual C++ prof 6 SP 5

I am fairly adept with c++ oo console programming.

I have been playing around with the win32 api. I have made a simple program which creates a pushbutton on the main window. When it's clicked it launches a dialog box where i wish to input data in an object.

Now i tried to create a class but the compiler will not recognize class xxxx{} ....it gives me errors....

what am i missing here....
even this simple one will not work:
class dayof year
{
public:
void output();
int month;
int day;
};
//// this in the dialog proc
dayofyear today;
////
void dayofyear::output();
{
}
Even trying structs gave me errors. Am i missing the whole point of win32 or what?


PLease help. Source code example with user defined class in simple win32 app would be nice.

class dayof year//Beware spaces where they shouldnt be
{
public:
void output();
int month;
int day;
};
//// this in the dialog proc
dayofyear today;
////
void dayofyear::output();
{
}

Still does not work... Gives me syntax error at the class xxxx line.

Am i missing a include or what am i doing wroing

I put the class def right after the includes. But it does not recognise this. Gives me syntax error

I'm not sure of exactly how your files are structured but this is what you would want:

(I just used "doty" to shorten the filename)

A file called doty.h which has:

#inndef DOTY_H
#define DOTY_H

#define WIN32_LEAN_AND_MEAN
#include <windows.h>

class dayoftheyear
{
public:
  //constructor
  dayoftheyear();
  //destructor
  ~dayoftheyear();
  void output();
  int month;
  int day;
};

#endit DOTY_H

A file called doty.cpp which has:

#include "doty.h"

dayotheyear::dayoftheyear()
{
    //clean out any previous variable values
    month=0;
    day=0;
}

dayoftheyear::~dayoftheyear()
{
   //clean up when you're done
   month=0;
   day=0;
}

void dayoftheyear::output()
{
    char cDay[20], cMonth[20];
    _itoa(day,cDay,10);
    _itoa(month,cMonth,10);
    strcat(cMonth,"/");
    strcat(cMonth,cDay);
    MessageBox(NULL,cMonth,"debug",NULL);
}

In your main *.cpp file:

#include "doty.h"

dayoftheyear dotyDay;

Of course, I filled in the output function with a some generic stuff, just for the sake of example. Is this how your files are structured? Also, I recommend having at least 2 more functions ( 1 to set the day value and 1 to set the month value, if not even 2 additional functions to return the values set from the day and month individually ).

The problem was i called my files with .c extension....whoops.

should be .cpp

Thanks for the help people
