It accepts three parameters.
The first "hwnd" must be NULL. It is not used.

The third "argv" contains parameters.

int
CSVtoXLS_ConverterStr(HWND hwnd, char *params);

It accepts two parameters.
The first "hwnd" must be NULL. It is not used.
The second "params" contains parameters which are delimited by #.
