C++Builder Developer's Journal

thanks Remy,
I didn't understand this part then I saw that if you don't use it, the timer continues indefinitely. So it is used to count the number of timer activations and when you have reached the desired number of activations, stop the thread; very interesting.

it is possible that the solution is simply adding Application-> ProcessMessages (); void __fastcall TMyThread::Execute() { TTimer *asd = new TTimer(NULL); asd->Interval = 500; asd->OnTimer = &MyTimer; asd->Enabled = true; msg = myip(StrToInt(myadr)); Synchronize(&MyMemo1); Sleep(1000); Application->...

I can't activate the OnTimer event but I don't see any problems, are there any? //--------------------------------------------------------------------------- #include <vcl.h> #pragma hdrstop #include "Unit1.h" class TMyThread : public TThread { private: void __fastcall MyTimer(TObject *Sender); prot...

sorry Remy, but you already answered me here

However, it was wanted to start a certain number of threads through a for () loop and then, when one of them ends, a new thread starts in its place. The example I gave you on Feb 5th does exactly that. sorry Remy, Once a thread terminates, it can't be reused. I had missed this sentence of yours, wh...

thanks Remy.

Thanks again

thanks Remy. If I have understood your code well, making these changes, as you also suggested to me, I can always keep in memory, for example, the same 5 threads and when one of these ends pass a new topic to this. I don't know if the changes I made to your code are correct to ultimately get 5 threa...

I still take advantage of your skills and ask you: we said that if I instantiate n threads without arrays, I lose all references and, if I want to do something about one of them, I can no longer do anything. By setting the FreeOnTerminate = true property; it is true that a thread is terminated at it...

great Remy as always. In this version of the code, if I introduce a certain number of attempts when ByteReceived == 0, would it make sense? I thought that ByteReceived returns 0 if at that moment the buffer is perhaps full or the server is overloaded: could it be so? #include <memory> void __fastcal...

thanks Remy.
So your advice is: with blocking sockets forget about events.

Anyway, I was insisting on the old road just to understand, thanks again Remy.

thanks Remy. After some tests I found this method to trace the handle of the thread that ends. void __fastcall TForm1::ThreadTerminated(TObject *Sender) { ThreadsRunning--; if (ThreadsRunning == 0) Caption = "Terminated"; TMyThread *MyTh = dynamic_cast<TMyThread*> (Sender); Memo2->Lines->Add( "stop:...

thanks Remy. because if I instantiate only 1 thread I don't lose data instead, if I instantiate 5 with different ip addresses I lose data? With 5 threads the data is truncated. void __fastcall TMyThread::Execute() { TClientSocket *MySock = new TClientSocket(NULL); MySock->Address = myadr; MySock->Po...

thanks Remy. Another thing I didn't understand: if I create a class that is similar to the one you showed me, and I instantiate n threads, do I finally have a private OnRead event for each thread? class TMyThread : public TThread { private: protected: void __fastcall Execute(); void __fastcall Socke...

......

this is a version where I try to extend the TClientSocket class but it doesn't compile and I don't understand why. The reason is that I want to implement the events unlinked from the Form but I don't know if it is the correct way. class MyTestClass : public TClientSocket { private: protected: public...
