CreateFile

[simmeone]

Hi,

I have a problem with the CreateFile function. The function create a file, thats OK, but, I realy don't know, how I can write any data into the file.
In the MSDN stands anything with FriteFile aso, but at the moment, I can't understand this.
Have anybody a clue, how this works ?

Thank you very much.

If you want to create files and write/read data, I would suggest you use the ifstream and ofstream functions. The good things with them is that you can write and read whole structures of data in one single call.

#include <fstream.h>

struct Test
{
public:
   int iVar;
   char cVar;
};

Test test_Struct;

void main()
{
   test_Struct.iVar = 45;
   test_Struct.cVar = 'H';

   // Write data to &quot;file.txt&quot;
   ofstream fout(&quot;file.txt&quot;,ios::binary);
   fout.write((char*)test_Struct, sizeof(Test));
   fout.close();

   // Read data from &quot;file.txt&quot;
   ifstream fin(&quot;file.txt&quot;,ios::binary);
   fin.read((char*)test_Struct, sizeof(Test));
   fin.close();
}
