佐手、 提交于 2019-12-12 04:22:27
问题 I am having a slight issue sending formCollection data to my controller action method in MVC using jQuery .Post method.

Why Can't These Templatized Functions Take No Arguments?

半城伤御伤魂 提交于 2019-12-12 04:06:58
问题 I am trying to use a couple templatized functions for Substitution Fail Is Not An Error(SFINAE). And I can do it like this: template<typename R, typename S = decltype(declval<R>().test())> static true_type Test(R*); template<typename R> static false_type Test(...); But I'm not understanding how the argument makes this SNFIAE work. It seems like I should just be able to remove the arguments and the template selection would work the exact same way: template<typename R, typename S = decltype

问题 I am trying to create a report in iReport based on an oracle SQL query which deals with transactions. The actual tables involved are very lengthy and are not really relevant to the issue.

How to initialize parameterized array parameter using loop/generate in verilog?

会有一股神秘感。 提交于 2019-12-12 03:17:34
问题 I want to initialize a parameterized array parameter as follow: parameter n = 4; parameter [(log2(n)-1):0] state [(n-1):0] = '{2'h3, 2'h2, 2'h1, 2'h0}; // for n=4 This assignment works fine if n=4. When n=8, it should initialize as {3'h7, 3'h6, 3'h5, 3'h4, 3'h3, 3'h2, 3'h1, 3'h0} I want to initialize it like this: for(i=0,i<n,i=i+1) state[i] = i; Now what should I use to do this initialization? Can I do it with generate? Here log2 is a function. 回答1: First off, you are using SystemVerilog,
