Re: [amibroker] I have a problem with AB4.54 running the enclosed AA

Hello,
 
Actually this is not the case.
It is possible to call OLE directly from AFL - 
calling methods was allowed long time ago,
now it is also possible to read properties - please 
check the READ ME from the latest release:
 

+ OLE properties can be retrieved (DISPATCH_PROPERTYGET) directly from AFL 
now using parameterless function syntax. This allows reading values exposed by 
OLE automation directly from AFL code. Example:
AB = <FONT 
color=#0000ff>CreateObject(<FONT 
color=#ff00ff>"Broker.Application"); Stocks = 
AB.Stocks(); // get collection<FONT 
color=#000000> Stock = Stocks.Item( <FONT 
color=#0000ff>Name() ); // 
currently selected <FONT 
color=#ff00ff>"FullName : " + Stock.FullName(); 
"Alias : " + 
Stock.Alias(); "Address : "<FONT 
color=#000000> + Stock.Address(); "Shares: 
" + Stock.Issue(); <FONT 
color=#ff00ff>"Book value: " + Stock.BookValue(); 
"Market : " + 
Stock.MarketID(); "WebID : "<FONT 
color=#000000> + Stock.WebID();
You can check if OLE object is valid by calling IsNull() function, 
example:
AB = <FONT 
color=#0000ff>CreateObject(<FONT 
color=#ff00ff>"Broker.Application"); Stocks = 
AB.Stocks(); // get collection<FONT 
color=#000000> Stock = Stocks.Item( <FONT 
color=#ff00ff>"INTC" ); <FONT 
color=#800000>if( <FONT 
color=#0000ff>IsNull( Stock ) ) { 
  printf<FONT 
color=#000000>("COM object invalid (Null) - symbol 
does not exist\n"); } <FONT 
color=#800000>else { 
  printf<FONT 
color=#000000>("COM object valid - you can access its 
methods\n"); 
}
