Borland C++ Builder 6 - Thread
Pokusao sam da stavim dva CGauge-a na formu koja ce da prate izvrsavanje dva inserta u bazu, evo koda, ali nesto ne stima,
uvek se odradi jedan pa drugi. Ima li neko ovakvih iskustava a spreman je da ih podeli sa drugima?
Unit1.cpp
TForm1 *Form1;
TMyThread *proc;
TMyThread *proc1;

__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
}
//---------------------------------------------------------------------------
void __fastcall TForm1::Button1Click(TObject *Sender)
{
TMyThread *proc = new TMyThread(false);
proc->Priority = tpNormal ;
proc->Suspend();
TMyThread1 *proc1 = new TMyThread1(false);
proc1->Priority = tpNormal;
proc1->Suspend();
proc->Resume();
proc1->Resume();
}
//---------------------------------------------------------------------------
void __fastcall TForm1::FormClose(TObject *Sender, TCloseAction &Action)
{
delete proc;
delete proc1;
}

int max = StrToInt(Form1->LEdit1->Text);
Form1->CGauge1->MaxValue = max;
for ( n=0; n<=max; n++ ){
Form1->SQL->SQL->Text = "insert into id (id,a,b,c) values ("
