Loop a collection with Realbasic
I'm work on a tool for learning purposes, it perform a search with google apis. Using HTTPSocket I get the results of the search in json format and then parse it to dictionary with the json.parser written by CharcoalDesign.co.uk
This is how looks json results:
{"responseData": {
"results": [
{
"GsearchResultClass": "GwebSearch",
"unescapedUrl": "http://en.wikipedia.org/wiki/Paris_Hilton",
"url": "http://en.wikipedia.org/wiki/Paris_Hilton",
"visibleUrl": "en.wikipedia.org",
"cacheUrl": "http://www.google.com/search?q\u003dcache:TwrPfhd22hYJ:en.wikipedia.org",
"title": "\u003cb\u003eParis Hilton\u003c/b\u003e - Wikipedia, the free encyclopedia",
"titleNoFormatting": "Paris Hilton - Wikipedia, the free encyclopedia",
"content": "\[1\] In 2006, she released her debut album..."
},
{
"GsearchResultClass": "GwebSearch",
"unescapedUrl": "http://www.imdb.com/name/nm0385296/",
"url": "http://www.imdb.com/name/nm0385296/",
"visibleUrl": "www.imdb.com",
"cacheUrl": "http://www.google.com/search?q\u003dcache:1i34KkqnsooJ:www.imdb.com",
"title": "\u003cb\u003eParis Hilton\u003c/b\u003e",
"titleNoFormatting": "Paris Hilton",
"content": "Self: Zoolander. Socialite \u003cb\u003eParis Hilton\u003c/b\u003e..."
},
...
],
"cursor": {
"pages": [
{ "start": "0", "label": 1 },
{ "start": "4", "label": 2 },
{ "start": "8", "label": 3 },
{ "start": "12","label": 4 }
],
"estimatedResultCount": "59600000",
"currentPageIndex": 0,
"moreResultsUrl": "http://www.google.com/search?oe\u003dutf8\u0026ie\u003dutf8..."
}
}
, "responseDetails": null, "responseStatus": 200}
The problem that i want to loop each value of "results" and add data to a listbox, without adding any other responseData (such as "cursor").
Dim d as Dictionary
Dim c as Collection
data = Json.parse(content) // use the class json.parse
d = data.Value("responseData")
c = d.Value("results")
After that i dont know how to loop each of "results" value, i've tryed many ways with for-each... works with dictionary, "for each key in d.Keys()", but not with colle开发者_StackOverflow中文版ction. Where i'm wrong?
To loop through a collection you need to access it through the Items function.
for i as integer = 1 to c.count //Collection is 1 based
dim s as string
s = c.item(i)
next
