问题 In VS2010, this function below prints "stdout in error state", I'm unable to understand why. Any thoughts on what I'm doing wrong? void printUnicodeChars() { const auto beg = 0x0030; const auto end = 0x0039; wchar_t uchars[end-beg+2]; for (auto i = beg; i <= end; i++) { uchars[i-beg] = i; // I tried a static_cast<wchar_t>(i), still errors! } uchars[end+1] = L'\0'; std::wcout << uchars << std::endl; if (!std::wcout) { std::cerr << std::endl << "stdout in error state" << std::endl; } else { std

问题 We've started to separate out our single VS solution into multiple solutions for better maintenance. I am wondering if there is any best practice out there for msbuild script that build across multiple solution that may depend on the same project dll. For example: solution 1 contains [proj1 and proj2] solution 2 contains [proj3 which needs a reference to proj2] Logically, solution2 cannot be build until solution1 is built. Also, the reference made to proj2 from solution2 should not be of the

问题 I am having some problems converting string to decimal values with decimal.parse. This is the line of code I have: fixPrice = decimal.Parse(mItemParts.Groups["price"].Value.Replace("$", "").Replace(" ", "").Replace("usd", "")); The value from which I am trying to convert is: '$779.99' Then once the parsing to decimal happens, I am getting this value: 77999. I would like to get 779.99 instead of 77999. Thanks in advance, Laziale Regex included: "@"\[^\""]+?)\""[^~]+?\]+?src=\""(?[^\""]+?)\""[^

问题 I'm playing with c++ in VisualStudio2010 Please explain why IT happens: int a, b; int *p, *q; cout << a << " " << b; prints out "0 0". Well it's understandable, uninitialized integer should be 0; but int a, b; int *p, *q; p = &a; cout << a << " " << b; output is "1792816880 0" So if I assign pointer to uninitialized variable it change value from default. Why? Edit clarification: the question was not about value of uninitialized variable int a; int *p; cout << a; // would be 0, because it's
