Mmmm it doesnt quite fit with what I want though.....

COM_Init()
pwhr := COM_CreateObject("WinHttp.WinHttpRequest.5.1")
psink := ConnectIWinHttpRequestEvents(pwhr)

Just a quick test.
Note: All the above code is Sean's. I copied and pasted it 
You see that those Sleep, 1000 are necessary and sometimes not adequate. The sleep needs to be increased and I sometimes (rarely) dont get all 3 results back with sleep 3000
It must depend on the system, so isnt really a very good example of asynchronous downloading, if such a massive gap is needed between files.
I need it to be quick, thats why I would want to download more than 1 file at once. Any ideas why it needs that massive sleep?
Also this still wouldnt work as how could I parse the information and have the listview usable on the gui? the info would need to be constantly parsing as fast as possible |

I assume each "request" object can only handle one request at a time... Create a WinHttpRequest object for each concurrent request, rather than trying to reuse the same object.

Try explaining that again, without using a question as a "reason."
What I'd like to know is how could you parse the information and not have the ListView usable. Since AutoHotkey checks for messages every 5 ms by default, the ListView should remain responsive while script is running (but maybe not during a DllCall.) Anyway, assuming you are parsing search results, the parsing function should be lightning fast compared to the actual download. |

Not much really. What's not practical to do in AHK code compared to alternatives might be a better way to phrase the question. Tasks that might require a lot of AHK code and/or workarounds can sometimes be accomplished easily in other languages, using command line utilities, etc... and then added to an AHK script using a relatively small amount of AHK code... For example, writing a dll (or using an existing one) to do various tasks then calling the dll from an AHK script can be very handy sometimes compared to writing long winded workarounds in AHK code  . |

| Aside from things you can't do in any language (like peel potatoes), I think an OS is about the only think you absolutely couldn't make. (Which didn't stop someone from asking, I recall.) |

Didn't try it, but you can use DllCall to allocate memory and then use this memory in subsequent API calls.

Arrays are no different to any other structure. A WORD is 2 bytes, so "three arrays of 256 WORD elements" = 3 * 256 * 2 = 1536 bytes.
| Code: | VarSetCapacity(array, 1536)
; array_index: zero-based index of array (0-2)
; item_index: zero-based index of item within the array (0-255).
NumPut(value, array, array_index*256 + item_index*2, "short")
|
That's a list in a string, not really an array. |
