okie i seriously dunno whether my own conversion is correct or not...i am trying to convert Mr LaMothe's struct engine to class type engine. this is for the header file, is a constructor necessary here? or must i call a default constructor, coz i dun find any data members to add into the constructors.
          
// class for bitmaps .BMP file

class BITMAP_FILE
{
public:

BITMAPFILEHEADER bitmapfileheader;  // this contains the bitmapfile header

BITMAPINFOHEADER bitmapinfoheader;  // this is all the info including the palette

PALETTEENTRY     palette[256];      // we will store the palette here

UCHAR            *buffer;           // this is a pointer to the data


/*
//default constructor
BITMAP_FILE();
*/

//member functions

int Load_Bitmap_File(BITMAP_FILE_PTR bitmap, char *filename);
};
          
and i couldnt find a place to put this: *BITMAP_FILE_PTR which is found on the previous structure. [edited by - edwinnie on May 6, 2002 9:58:00 AM]

for: *BITMAP_FILE_PTR

do:

typedef BITMAP_FILE* BITMAP_FILE_PTR;


Your data members should be private, and the methods (Load_Bitmap_File) public. Also, your methods (L_B_F) don''t have to take a BITMAP_FILE_PTR, because it is now a class and refers to itself via the "this" pointer.. you no longer need to pass the object to load the data into.
