Before and after events

[sdean]

i'm trying to implement a Before and After Event onTime :

how could i do an event before Min Value 'in this case 5 minutes ' ?

Delphi-Quellcode:

Procedure Before(Min:Word);
Var
Tm:TTime;
begin
Min:=5;// 5 Miutes
Tm:=Now;
{
for example :
if before 5 Minutes then 
ShowMessage('5 minutes to go ');
}
end;

how could i do an event after Min Value 'in this case 5 minutes ' ?

Delphi-Quellcode:

Procedure After(Min:Word);
Var
Tm:TTime;
begin
Min:=5;// 5 Miutes
Tm:=Now;

{
for example :
if after 5 Minutes then 
ShowMessage('5 minutes passed');
}
end;

Zitat:

i'm trying to implement a Before and After Event onTime :

Depending on what?

Code:

if before 5 Minutes then

Delphi-Quellcode:

if Tm - (Min / 24 / 60) = ... then

When using a TTimer or equivalent never check for equality!
e.g.

Delphi-Quellcode:

if Abs(Tm - (Min / 24 / 60) - ...) < {interval} then

Min is not a good variable name, especially if it integrates the unit Math.

Thank you himitsu

All depends on the Current Time :

i use TTimer .

if X minutes to the current time then Before

if X minutes passed from current time then after

i hope i gave a little detail

I reformed my Question as follows :

how could i do an event before Min Value 'in this case 5 minutes ' ?

Delphi-Quellcode:

Procedure Before(Min:Word); 
Var 
 Sm, // System Time ; Time to compare To 
 Mt: // My Time ; Time to compare with

S:String;
TTime;
begin 
S:='10:05:00';
Min:=5; // 5 Miutes 
Sm:=Now;          // system time 
Mt:=StrToTime(S);//  My Time
{ 
Let's suppose the fowlling :
Sm:=10:00:00;  // System Time
Mt:=10:05:00; //  My Time
That means it's 5 minutes to rich Mt time '10:05:00'

if before 5 Minutes then 
ShowMessage('5 minutes to rich My Time '); 
} 
end;

how could i do an event after Min Value 'in this case 5 minutes ' ?

Delphi-Quellcode:

Procedure After(Min:Word); 
Var 
 Sm, // System Time ; Time to compare To 
 Mt: // My Time ; Time to compare with

S:String;
TTime;
begin 
S:='10:00:00';
Min:=5; // 5 Miutes 
Sm:=Now;          // system time 
Mt:=StrToTime(S);//  My Time
{ 
Let's suppose the fowlling :
Sm:=10:05:00;  // System Time
Mt:=10:00:00; //  My Time
That means it's 5 minutes passed from Sm time '10:05:00'

if after 5 Minutes then 
ShowMessage('5 minutes passed from system time '); 
}
end;
