character

问题 I'd like to retrieve the ANSI code value of a given character. E.g. when I now get the int value of the trademark character, I get 8482. Instead I would like to get 153, which is the value of the trademark character in codepage 1252. Some help would be appreciated. Jurgen 回答1: Found it myself: Encoding ansiEncoding = Encoding.GetEncoding(1252); byte[] bytes = ansiEncoding.GetBytes(c); int code = bytes[0]; 来源： https://stackoverflow.com/questions/12370812/c-sharp-get-ansi-code-value-of-a

问题 I am trying to input two characters from the user t number of times. Here is my code : int main() { int t; scanf("%d",&t); char a,b; for(i=0; i<t; i++) { printf("enter a: "); scanf("%c",&a); printf("enter b:"); scanf("%c",&b); } return 0; } Strangely the output the very first time is: enter a: enter b: That is, the code doesn't wait for the value of a . 回答1: The problem is that scanf("%d", &t) leaves a newline in the input buffer, which is only consumed by scanf("%c", &a) (and hence a is

问题 I'm trying to match a search string with a file name with a recursive directory search on Android. The problem is that the characters are Japanese, and it's not matching in some cases. For example, the search string I'm trying to match the start of the file name with is “呼ぶ”. When I print the file names, from file.getName(), this is accurately reflected, e.g. the file name printed to the console starts with “呼ぶ”. But when I do a match on the search string, e.g. fileName.startwith(“呼ぶ”), it

问题 Using: Rails 3.0.3. I have a string that could be seen as this one: <p>hello, how are you? oh, that's nice! i am glad you are fine. i am too.<br />i am glad to have met you.</p> I want each character following any of <p> <br /> ! ? . to be capitalized. Basically make the string above look good. Is there a standard functionality for that? What should I do? ps.

问题 I am reading data from a stream (provided by a process) character by character and adding it to a textbox so the user can see. The only problem is, this is SLOW . The user needs to see the data as it is given to the program (with little to no delay). I would like something like how terminals handle text, it can scroll by so fast that it's a blur. How can I improve this? For reference, I'm using C# .net3.5 and winforms. 回答1: The Text property of the text box is a string, and strings are

问题 Cannot find a solution to seem to be a simple question. For example, I have a string with LineBreak ”a\na”. The System.out.println output of this string shows 2 lines. However, I need to show the output in exactly the same form, i.e. “a\na”. How to achieve this? 回答1: You need to escape your \n with an extra backslash.. Use: - "a\\na" to get \n in your output.. System.out.println("a\\na"); // Prints a\na Or, you can also take a look at :- Apache Commons StringEscapeUtils#escapeJava which will

问题 This question already has answers here : Pygame: Is there any easy way to find the letter/number of ANY alphanumeric pressed? (2 answers) Closed last year . I have a Pygame program that needs text input. The way it does this is to get keyboard input and when a key is pressed it renders that key so it is added to the screen. Essentially it acts like a text field. The problem is, when you hold shift it doesn't do anything. I realize this is because the program ignores shift input and instead
