USE API PROGRAMMING TO REALIZE WINDOWS SYSTEM TIME AND DATE

I tried my best. Don't ask me what the arguments mean. Because I don't know either.

There is no API to get yesterday's date directly, this is the apivoid winapi to get the current date GetSystemTime( Out lpsystemtime lpsystemtime

This is OKLPSYSTEMTIME is the systemtime pointer after getting today, and then extrapolating yesterday's from today's date.

Judge today's date, and if it's the 1st, then judge the month. According to the month of the previous month, if it is yesterday, it is OK to subtract 1 day directly

Upstairs is the right solution.

It's true that there is no direct access to yesterday's date"Smart API".

Need to pass the calculation. For example, define the maximum number of days in a month for global data.

int daylist[13] = ;

Note: daylist[0] refers specifically to the number of days in February in leap years, and the number of months corresponding to other daylist[1] to daylist[12] respectively.

systemtime time;

getsystemtime(&time)

if ( == 1) if it is 1.

elseps: I guess remember the number of days per month.

1: I didn't say anything about visiting 1500 at a time, and you forgot about it.

2: Browse roughly, find what you are interested in and what you are using nowadays, and use it while watching, I think so.

3: Or that LZ's memory is good, and I can't remember 7788 after reading it. Take a look at what you have at hand.

To add buttons and text boxes, you can see the lpclassname and dwstyle parameters of cretewindowex. (The standard controls provided by Windows have a corresponding classname and a lot of flavors - see MSDN for details).

suspendthread suspendthread resumeThread resume, exit thread can use exitthread

Get Time: Don't know if you get Greenwich Mean Time or System Clock? getsystemtime to get Greenwich Mean Time.

GetSystemTimes Get System Clock Note: All of these can be found via MSDN.

The time seems to have a datetimepicker control, and this control can be used.

I can introduce a book to the last two questions.

MUD Game Programming", the first few chapters are about threads. as well as the API for time.

Hope it helps.
