可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: So in the text editor program that i've been working on, I've used WM_CHAR to process input from the keyboard. However, I found that some of the character mesages are not recorded. For example, if I use [shift]+ number key to type a symbol such as % or &, some re recorded while others such as [shift]+9 (which results in ')'), are not recorded. So, I'm wondering if I should use WM_KEYDOWN/WMKEYUP pair to handle keyboard input. I once wrote a keylogger in assembly(actually it was just a tutorial that i was trying out) and had used WM_KEYDOWN

One way I tried to do this is by creating a class where I would put the each key name of my dictionary, so that they would be different objects: names = ["1", "1"] values = [[1, 2, 3], [4, 5, 6]] dict = {} class Sets(object): def __init__(self,name): self.name = name for i in range(len(names)): dict[Sets(names[i])] = values[i] print dict The result I was expecting was: {"1": [1, 2, 3], "1": [4, 5, 6]} But instead it was: {"1": [4, 5, 6]} [EDIT] So I discovered

Alamofire.request("http://codewithchris.com/code/afsample.json").responseJSON { response in if let JSON = response.result.value { print(JSON) } } The issue is that when I run this: Alamofire.request("http://codewithchris.com/code/afsample.json").responseJSON { response in if let JSON = response.result.value { print(JSON["firstkey"]) } } I get the error: Type 'Any' has no subscript members I don't know

But using this code, I lose some information of the dictionary, getting this output: {'LinMotion': 10, 'PtpMotion': 9, 'Wait': 11} Why does it happen? 回答1: Each key can only occur once in a dictionary. You could store a list of

.net - dictionary.Keys.Add?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: In .Net, IDictionary<K, V> defines .Keys and .Values properties, each of which is an ICollection<> rather than IEnumerable<> , which seems like it would be a more natural fit to me. Is there any reasonable use case to call .Add or .Remove on .Keys or .Values of an instance of an IDictionary<K, V> ? 回答1: No, probably no reasonable use case. There are very few (probably zero) legitimate reasons for this at all. The Dictionary<TKey, TValue> class returns a KeyCollection for its .Keys which in turn throws NotSupportedException with "Mutating a

Iterate over all keys of nested map

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: Given: {:o {:i1 1 :i2 {:ii1 4}}} I'd like to iterate over the keys of the map in "absolute" form from the root as a vector. So I'd like: { [:o :i1] 1 [:o :i2 :ii1] 4 } As the result. Basically only get the leaf nodes. 回答1: A version that I think is rather nicer, using for instead of mapcat : (defn flatten-keys [m] (if (not (map? m)) {[] m} (into {} (for [[k v] m [ks v'] (flatten-keys v)] [(cons k ks) v'])))) The function is naturally recursive, and the most convenient base case for a non-map is "this one value, with no keyseq leading to it".
