问题 Let's say I have this variable: word = "habit" which command in VBA will allow me to count how many characters are there in this variable (in my case it's 5). Important: the variable "word" contains only one word, no spaces, but may have contain numbers and hyphens. 回答1: Do you mean counting the number of characters in a string? That's very simple Dim strWord As String Dim lngNumberOfCharacters as Long strWord = "habit" lngNumberOfCharacters = Len(strWord) Debug.Print lngNumberOfCharacters

问题 I'm currently using 'data:post.snippet' for blogger mobile snippet. <div class='post-body' style='color:black;'> <b:if cond='data:post.snippet'><data:post.snippet/></b:if> </div> But its character length(140) is too low, and it doesn't give a line break between the headings and paragraphs.

问题 I need to find out the names for Unicode characters when the user enters the number for it. An example would be to enter 0041 and get given "Latin Capital Letter A" as the result. 回答1: As far as I know, there isn't a standard way to do this. You could probably parse the UnicodeData.txt file to get this information. 回答2: Here should be what you're looking for. The first array is simply http://unicode.org/Public/UNIDATA/Index.txt with replacing newlines with | ; // this mess.. var unc = "A WITH

问题 I need a function that returns the ASCII value of a character, including spaces, tabs, newlines, etc... On a similar note, what is the function that converts between hexadecimal, decimal, and binary numbers? 回答1: char c; int ascii = (int) c; s2.data[j]=(char)count; A char is an integer, no need for conversion functions. Maybe you are looking for functions that display integers as a string - using hex, binary or decimal representations? 回答2: You don't need a function to get the ASCII value --

问题 EDIT: Thanks to GOTO 0 , I now know exactly what I my question is called. I need a JavaScript function to convert from UTF-8 fullwidth form to halfwidth form. 回答1: Try this function toASCII(chars) { var ascii = ''; for(var i=0, l=chars.length; i<l; i++) { var c = chars[i].charCodeAt(0); // make sure we only convert half-full width char if (c >= 0xFF00 && c <= 0xFFEF) { c = 0xFF & (c + 0x20); } ascii += String.fromCharCode(c); } return ascii; } // example toASCII("ＡＢＣ"); // returns 'ABC' 0x41
