I'm creating a .bmp file using this CreateFileA method
HANDLE hFile = CreateFileA("Screenshot01.bmp", GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
At the moment is static and just keeps re-writing the old file.
I want to call this method multiple time, each time it will create a new file with a different file name, for example
"Screenshot01.bmp" "Screenshot02.bmp" "Screenshot03.bmp" etc.
It doesn't have to increment, but the file name should be different each time.
How do I change the file name each time the method is called? Are you able to assign the File name to a Variable?
Use a std::string. For instance:
#include <string>
....
std::string filename = "Screenshot01.bmp";
HANDLE hFile = CreateFileA(filename.c_str(), ...);
To build the file name up from an integer you might do this:
#include <string>
....
std::string filename = "Screenshot" + std::to_string(id) + ".bmp";
HANDLE hFile = CreateFileA(filename.c_str(), ...);
How do I change the file name each time the method is called?
Keep track of the most recently used id value, and increment it when you need a new value.
