Hello,
 
That's exactly the point - you can not "stop" the execution of formula in real-time application,
because it will stop responding.
That's why Popup WIndow is opened in asynchronous (non-modal) and does not stop execution.
 
To provide "single-step" debugging and stopping the formula execution in the middle you 
would need to run EACH formula in completely separate thread. Only that way real-time application
would be able to continue working with one tread stopped in the middle waiting for the user to push the button.

Modal argument is correct of course because MessageBox() is openend in Modal
mode. But what if the Form of the MessageBox() is being set to Modeless or
'Non Modal' ? Isn't that possible ? More or less the same you did with PopupWindow.
I am not talking about the usual MessageBox() function of course because then
you will have your Modal problem  ...
 
_TRACE works fine but what if I want to do a 'step by step' debugging ? So that
I can stop the program at a certain point and see what a certain variable gives me.
Something I cannot do now with the new PopupWindow function. At least that's
what I think. Let's say I've put a PopupWindow in a loop and I want to show the values
of a variable sequentially. Something like ...
 
y0   = LastValue(Trough(L,percent,firstpointL));
y1   = LastValue(Trough(Ref(L,-1),percent,1));

for( i = 1; i < BarCount AND y0 >= y1; i++ )
{   
      firstpointL++;   
      y0=LastValue(Trough(L,percent,firstpointL)); 

      //_TRACE("y0="+WriteVal(y0,1.2)+" "+   "y1="+WriteVal(y1,1.2));    
      PopupWindow("Y0 :"+WriteVal(y0),"Debugging", 10, 10, 10);
}
ETC.
 
By hitting the CLOSE button in the PopupWindow it gives me the values. But the
program is not stopping at the point where I have put the PopupWindow in the
code. If this is correct, I cannot do a step by step debugging. Function should
be available in DebugView. But to my knowledge it isn't and probably for a
good reason ...
 
Regards, Ton.

Ton,
 
Modal Message Box is no-no because it will lock execution until you press the button
- not something what you would like to do in REAL TIME charting application.
 
PopupWindow is much different because it is ASYNCHRONOUS (non-modal).
 
For debugging - use _TRACE - it is much more effective than message boxes.
 
AmiBroker also provides superior methods for providing input from GUI,
by means of Param... functions. They are asynchronous (non-modal) as well
and much more comfortable than modal dialogs.

Functions that are standard stuff in other programming languages - like
MessageBox() - for me should be available in AFL also. There are many
occasions where I will need it. Although I would like to have the full
functionality of MessageBox() in the PopupWindow and not just the Close
button,  it's a good start. If you want an example look to the readme for
release 4.97.0 of AB. It's what it says that it is, a Popup Window. So
where ever you want a text to popup without forcing the user to take action
this function is helpful. You may also use it for debugging purposes, just to
give you an example where I am using MessageBox() quite often ...
 
Regards, Ton.

Herman and Ton - Is this function especially helpful in real-time automated trading?  Would
you give us an example on how you find it helpful?
 
Regards
Joe
