But seen in task manager memory footprint is more than 24 m.

I also changed the new and delete matching problem, and considering the TCP client may exit among any position, also bring new and delete in this format to write.

Try
{
The new...
}
__finally
{
The delete...
}

In addition, after the "Out of memory" message, sure, program will continue to run, until after several times, several days after the crash.

There are two TIdTCPServer, a common have 130 or so links, another is about 5.

Upgrade to the latest version of the indy

CodePudding user response:

I think this is only a memory leak of the reason, in addition to the new delete and there is no other memory processing

General tips "Out of memory", what is Out of memory, because the task manager to see memory only use for more than 24 m.

CodePudding user response:

TIdTCPServer OnExecute event is executed in the thread
Therefore never carried out within the OnExecute events related to redraw the control interface operation
Reason: the cause message blocking.

For example:

OnExecute () event
{
NetwowkSpeed - & gt; Caption=IntToStr (Value);//NetwowkSpeed TLabel
}


To:

Add a component TTimer * Timer1
Add a variable: int SpeedValue

OnExecute () event
{
SpeedValue=https://bbs.csdn.net/topics/Value;
}

To build a TTimer
Timer1Timet () event
{
NetwowkSpeed - & gt; Caption=IntToStr (SpeedValue);
}

So do not be "Out of memory"

CodePudding user response:

If it is:
Try
{
The new...
}
__finally
{
The delete...
}

Has nothing to do with new and delete matching problem!

Yes, I now thread is not about the interface and the database related operations, are each thread has a corresponding structure in staging, and then the main thread of a timer timing to deal with.

Another behind that

 try 
{
The new... 
} 
__finally 
{
The delete... 
} 

Is it possible for new returns null, and then back to perform the delete and there is an error?

CodePudding user response:

Basically not possible, either to:

Obj=new...

If (obj)
Try
{
.
}
__finally
{
The delete obj.
}
