Convert this from VB to C++

[WildGhost]

How would I convert this to C++ code?? (I'm using visual C++)

type header
namefile as string * 16
filesize as long  'size of file
fileoffset as long 'Byte where the file's data starts from
end type

dim head as header

open "C:\file.xxx" for binary access read lock write as #1

get #1, 1, head

dim filedata(head.filesize - 1)
get #1,head.fileoffset,filedata

open "C:\blah.bmp" for binary access write lock write as #2
put #2,1,filedata
close #2
close #1

Try this.

#include <fstream.h>

struct header {
	char namefile[16];
	long filesize;
	long fileoffset;
};

int main()
{
	header head;
	ifstream file("C:\\file.xxx", ios::binary);
	file.seekg(1);
	file.read((char*) &head, sizeof(header));
	char *filedata = new char[head.filesize -1];
	file.seekg(head.fileoffset);
	file.read( filedata, head.fileoffset-1);
	file.close();
	
	ofstream newfile("C:\\Blah.bmp", ios::binary);
	newfile.seekp(1);
	newfile.write( (char*) filedata, head.fileoffset-1);
	newfile.close();

	delete[] filedata;

	return 0;
}

Thanks a lot meg... I had to edit a bit to get it to work.. the reason it didn't work was because you didn't know the file format in the type.. so it's not your fault.. but this is what I did to make it work...

 
#include <stdlib.h>

#include <fstream.h>

struct header {
	char namefile[16];
	long fileoffset;  //This was below, I brought it up...
	long filesize;    // Because file had offset written first.
	
};

int main()
{
	header head;
	ifstream file("C:\\file.xxx", ios::binary);
	file.seekg(8);
	file.read((char*) &head, sizeof(header));
	char *filedata = new char[head.filesize]; 
	file.seekg(head.fileoffset);
	file.read( filedata, head.filesize); //Changed to head.filesize because offset was the byte at which the data started, 
	file.close();
	cout << head.namefile;

	ofstream newfile("C:\\Blah.bmp", ios::binary);
	newfile.seekp(1);
	newfile.write( (char*) filedata, head.filesize);  
	newfile.close();

	//delete[] filedata;

	return 0;
}

ALso I removed the '- 1' from the code, because only VB needs them, C++ is fine with it. THanks again!!!
