Waiting in C++ Builder

[Maingoka]

Hi!
How to make a function wait for x seconds before doing something??
Example: When I click a button: in the onmousedown, I want to wait 1 second before it executes a function
Thank you

Look at the TTimer component or sleep. James P. Cottingham

#include <dos.h>

long delay = 500; // 5 sec.,delay in hundred of second
struct time oldt;
struct time newt;

gettime(&oldt);

for(;
{
gettime(&newt);
long t = (newt.ti_hund-oldt.ti_hund) +
100*(newt.ti_sec - oldt.ti_sec) +
6000*(newt.ti_min - oldt.ti_min);
if(t >= delay)
break;
}

Sleep(number of milliseconds to wait)
suspends the execution of your program.

Or you use a TimerComponent and with your mousedownevent you enable the timer (Timer->Enabled=true)
In your TimerEvent (Timer->OnTimer)you first set the Timer->Enabled to false (otherwise you keep on triggering your event) and then you put the code you want to execute after 1 second.

Personally I would prefer the second solution, in a windows environment I find it a bit tricky to really suspend the execution of a program,but it works.

use
Sleep(NumberOfMillisecons);//is much easier. John Fill
