Preventing context sensitive help searching beyond APL Help

Postby AndyS|Dyalog on Mon Jul 11, 2011 3:19 pm

If in a very basic Windows environment you attempt for example the following


Then a help window will appear with a Page Not Found error .. but at least you regain control of both APL and the help window almost instantaneously.

If however you have Visual Studio installed, then hitting <F1> on a non-existant keyword will result in a help window and APL session that remain unresponsive for some seconds.

You can at least prevent this unwanted delay by setting the registry key

HEKY_CURRENT_USER\Software\Dyalog\<your_Dyalog Version>\DefaultHelpCollection

to be empty (or even delete the key). You'll still get the help window (we're looking at suppressing that too!) but you will get control back immediately !
