The specific steps to use Settime in mfc

You're talking about settimer, right?

uint_ptr settimer(

hwnd hwnd, window handle.

uint ptr nidevent, timer ID, which can be used to determine which timer is the one when there are multiple timers.

uint nelapse, time interval in milliseconds.

timerproc lptimerfunc function.

If you're using it in MFC, it's already encapsulated, so you don't need to specify the hwnd parameter.

The iidevent flag is generally a self-defined flag, for example, a timer is needed to calculate time, and a timer is needed to calculate other things, that is, different timers need to be distinguished.

Nelapse is how often the timer is triggered.

The last parameter is the ** function, which means which function is needed to process the data when the timer is triggered, and when it is set to null, it is called the ontime function, and you can overload the function in mfc.

For example. #define um_timer wm_user+1

settimer(um_timer,1000,null);Triggers every 1 second interval and uses the ontimer function.

And then. c**:ontimer(uint_ptr nidevent)

if(nidevent == umtimer)

This place fills in with what you need to deal with.

First, add :settimer(); Start the timer. Then you can pass the function.

getlocaltime(&nowtime);Gets the system time and passes it to m nowtime

m_"%d-%d-%d::%d:%d:%d"), you can get the current time.

To stop the timer, all you need is killtimer(1).

Function name: settime

Function: Set the system time.

Usage: void settime(struct time *timep);

Example: include

#include

int main(void)

struct time t;

gettime(&t);

printf("the current minute is: %d", ;

printf("the current hour is: %d", ;

printf("the current hundredth of a second is: %d", ;

printf("the current second is: %d", ;

add one to the minutes struct element and then call settime */

settime(&t);

return 0;
