converting a "time_t" character to an int, char *

[Guest_imported]

Hi:

Is there a way to convert from a time format to an int, double or a char*?

Like:

time_t t1;
time(&t1);

char timeToday = (char *)t1 // which gives error ofcourse


Any suggestion will be appreciated!

Also is there a was to get the current date into a single variable and add say 7 or 30 days to it. Any add function with Date in visual c++? ..... Thanx much.

If you want to add/subtract something to/from a time variable have a look at CTime and CTimeSpan (MFC classes).

I figured the time add+ sub part. thank you for the suggestion though.

Antoher Question: I am trying to write that value to a registry and then re-read it. But I always get a ZERO read in even when the value in registry is NOT ZERO. (and this is to save the time in registry). Any ideas? Thank you.

here's my code to read in from the registry.... by the way it does work if I read in a LPCSTR type. but that doesn't work for date????

char defvalue[1024];
HKEY hkey2;
HKEY hkey1 = HKEY_CURRENT_USER;
LPCTSTR lpSubKey1 = "Software\\Testing";

error_value = RegOpenKeyEx( hkey1, lpSubKey1, 0, KEY_READ, &hkey2 );

ret_Val = RegQueryValueEx(hkey2, keyname , NULL,
&Type, (LPBYTE)&defvalue,
&size1);
