Execution error in Optimize=1 and/or debug mode.

#property strict

class A
{
public:  
  bool operator ==( int ) const { return(true); }
};

void OnStart()
{
  Print((A*)NULL == 0); // Optimize=1 or _DEBUG - invalid pointer access. Optimize=0 and _RELEASE - no problem.
}

A100:

Confusing macro highlighting - context-independent

either always present (option B) or always absent (option A)

It was expected that if a macro was defined in a particular string it would be highlighted, if it was not defined it would not be highlighted. Otherwise it's not clear what presence/absence of highlighting means.

Is it on the site? The engine on the site cannot recognise custom macros in the code

Always wondered why the text in OBJ_BUTTON buttons is offset ???

It doesn't look nice when creating miniature panels...

Thank you for your hard work and it's cool...

Try reducing the size of the arrow. I had the same thing.

CHART_KEYBOARD_CONTROL

Enables keyboard control of the chart ("Home", "End", "PageUp", "+", "-", "Up Arrow", etc.). Setting CHART_KEYBOARD_CONTROL=false allows to disable scrolling and scaling of the chart but still allows to receive events when these keys are pressed inOnChartEvent().

bool

can I also disable the Copy and Paste (Ctrl+C Ctrl+V) commands? so that I can copy text from the EDIT field

Vladimir Pastushak:

cool how it works...
