Typecasting for Class of Template Data type to unsigned char *

[KYAW KYAW OO]

Dear All,


I am searching the way for Typecasting for Class of Template Data type to unsigned char *. Although I tried to browse in the internet and solve my best of knowledge, the issue is still there and here is my coding of conversion.


a.h

class A
{


}

types.h

typedef unsigned char  c_UInt8;

main.cpp

HBITMAP hBitmap = (HBITMAP)LoadImage(NULL, fileName,IMAGE_BITMAP,0,0,LR_DEFAULTSIZE|LR_LOADFROMFILE);
	
BITMAP m_sbmpBitmap;
A<c_UInt8> greyImage(m_sbmpBitmap.bmWidth,m_sbmpBitmap.bmHeight);
unsigned char * retImage = (unsigned char*) greyImage;

I hope someone's advise to me since I am very tight in my development's schedule.

Thanks in advance

If you mean you want a (unsigned) char * to the data contained by the class A which I assume is probably actually a dynamic array of some sort then the answer is you can not use a cast, you need to write a method on the class.

You could write a casting operator but on the whole that is bad practice.
