  • SSAS error when deploying cube in BIDs

    - by user282382
    I am getting the following error when deploying. This is in a cube which was working fine, all that has changed is a key column in one of the dimensions. Internal error: Failed to generate a hash string I have no idea what is causing this but even if I change the dimension back to how it was and try to deploy I get the same error. If anyone has seen this or knows how to fix it please respond.

  • Does single or double quote matter in str_ireplace in PHP ?

    - by Richards
    Hi, I've to replace newline (\n) with & in a string so that the received data could be parsed with parse_str() into array. The thing is that when I put \n in single quote it somehow turns out as to be replaced with a space: str_ireplace(array('&', '+', '\n'), array('', '', '&'), $response) "id=1 name=name gender=gender age=age friends=friends" But when I put \n in double quotes then it works just fine: str_ireplace(array('&', '+', "\n"), array('', '', '&'), $response) "id=1&name=name&gender=gender&age=age&friends=friends" Why is that so?

  • C++ Template const char array to int

    - by Levi Schuck
    So, I'm wishing to be able to have a static const compile time struct that holds some value based on a string by using templates. I only desire up to four characters. I know that the type of 'abcd' is int, and so is 'ab','abc', and although 'a' is of type char, it works out for a template<int v> struct What I wish to do is take sizes of 2,3,4,5 of some const char, "abcd" and have the same functionality as if they used 'abcd'. Note that I do not mean 1,2,3, or 4 because I expect the null terminator. cout << typeid("abcd").name() << endl; tells me that the type for this hard coded string is char const [5], which includes the null terminator on the end. I understand that I will need to twiddle the values as characters, so they are represented as an integer. I cannot use constexpr since VS10 does not support it (VS11 doesn't either..) So, for example with somewhere this template defined, and later the last line template <int v> struct something { static const int value = v; }; //Eventually in some method cout << typeid(something<'abcd'>::value).name() << endl; works just fine. I've tried template<char v[5]> struct something2 { static const int value = v[0]; } template<char const v[5]> struct something2 { static const int value = v[0]; } template<const char v[5]> struct something2 { static const int value = v[0]; } All of them build individually, though when I throw in my test, cout << typeid(something2<"abcd">::value).name() << endl; I get 'something2' : invalid expression as a template argument for 'v' 'something2' : use of class template requires template argument list Is this not feasible or am I misunderstanding something?

  • Add characters (',') every time a certain character ( , )is encountered ? Python 2.7.3

    - by draconisthe0ry
    Let's say you had a string test = 'wow, hello, how, are, you, doing' and you wanted full_list = ['wow','hello','how','are','you','doing'] i know you would start out with an empty list: empty_list = [] and would create a for loop to append the items into a list i'm just confused on how to go about this, I was trying something along the lines of: for i in test: if i == ',': then I get stuck . . .

  • Can IDL evaluate strings as code?

    - by Carthage
    Is there any functionality in IDL that will allow it to evaluate a a string as code? Or, failing that, is there a nice, dynamic way of including /KEYWORD in functions? For example, if I wanted to ask them for what type of map projection the user wants, is there a way to do it nicely, without large if/case statements for the /Projection_Type keyword it needs? With even a small number of user options, the combinations would cause if/case statements to get out of hand very quickly to handle all the possible options.

  • C++: Chr() and unichr() equivalent?

    - by alex
    I could have sworn I used a chr() function 40 minutes ago but can't find the file. I know it can go up to 256 so I use this: std::string chars = ""; chars += (char) 42; //etc So that's alright, but I really want to access unicode characters. Can I do (w_char) 512? Or maybe something just like the unichr() function in python, I just can't find a way to access any of those characters.
