Hello Everyone..

Am working on the Trading Platform. I'm having a situation like where i need to run two operations ( Open & Close Operations ) infinitely. let me elaborate it clearly :

C++

void CTradingPlatform : OnBnClickedOPEN()
{
  while(1)
  {
    // Based on some conditions.. //code for the Open Opeartion here ...
  }

}

void CTradingPlatform : OnBnClickedCLOSE()
{
 while(1)
 {
  // Based on some conditions.. code for CLOSE Operation here..
 }
}

Here the problem is.. I cant run these two while loops at a time. I can run only one of them. These two while loops must run at a time. Is there any solution for this.. Please suggest me on this..

Thank you all :)

Solution 1

Unless the loops are synchronized in some rigid manner, so you could write them in a single loop, the only way to do this is to execute them in different threads. As UI is also involved (otherwise why would you use MFC?), even one loop will need a separate thread. In other words, for two loops, you will add at two threads to existing UI thread, to have at least three threads in total.

yeah.. I have created two threads like this..

UINT Thread1(LPVOID lParam)
{
while(1) {
//Code for Open Operation..
}

return(1);
}

UINT Thread2(LPVOID lParam)
{
while(1)
{
//Code for Close Operation..
}

return(1);
}

void CTradingPlatform : OnBnClickedOPEN()
{
AfxBeginThread(Thread1,0);

}

void CTradingPlatform : OnBnClickedCLOSE()
{
AfxBeginThread(Thread2,0);
}

Now this works fine.. Thank you..
