问题 What is the maximum length for the text string contained in a CEdit control in MFC? I get a beep when trying to add a character after the character 30001 is this documented anywhere? Can I display longer texts in a CEdit? Should I use another control? As "Windows programmer" says down below, the text length limit is not the same when the user types as when we programatically set the text using SetWindowText. The limit for setting a text programatically is not mentioned anywhere. The default

问题 I want to go through each character in a String and pass each character of the String as a String to another function. String s = "abcdefg"; for(int i = 0; i < s.length(); i++){ newFunction(s.substring(i, i+1));} or String s = "abcdefg"; for(int i = 0; i < s.length(); i++){ newFunction(Character.toString(s.charAt(i)));} The final result needs to be a String. So any idea which will be faster or more efficient? 回答1: As usual: it doesn't matter but if you insist on spending time on micro

问题 I am creating a small console app that needs a progress bar. Something like... Conversion: 175/348 Seconds |========== | 50% My question is, how do you erase characters already printed to the console? When I reach the 51st percentage, I have to erase this line from the console and insert a new line. In my current solution, this is what happens... Conversion: 175/348 Seconds |========== | 50% Conversion: 179/348 Seconds |========== | 52% Conversion: 183/348 Seconds |========== | 54% Conversion

问题 In Java, \' denotes a single quotation mark (single quote) character, and \" denotes a double quotation mark (double quote) character. So, String s = "I\'m a human."; works well. However, String s = "I'm a human." does not make any compile errors, either. Likewise, char c = '\"'; works, but char c = '"'; also works. In Java, which is better to use? In HTML or CSS, things like style="font-family:'Arial Unicode MS';" are more often (and for such tags, I think it's the only way to use quotation

问题 I am a new Android developer. I'm working with a Latin font in my app but I can't get it to work and keep getting a ? for the character. My code is below, using an sqlite database.I have to fetch text from an Sqlite database and every special Latin character (i.e. à, ò, ù, è...) was displayed with black squares with a "?" inside. How can i display this correctly? private void displayTestQuestion() { resetEverything(); stats.setText(Integer.toString(totalRightQuestions)+"/"+Integer.toString

问题 How do I change the character spacing in a WPF application within a textblock. Also known as kerning or tracking for characters. 回答1: An answer on social.msdn suggests the use of Glyphs. Other than that FontStretch allows for some adjustment. 回答2: Maybe you can add a Behavior for that TextBox that would go over every character and add a space after it. Alternatively, If you're using DataBinding, use a Converter with the same logic. And if you want to go for an overkill, you can make a custom

问题 I started learning HTML + CSS a week or two ago, and I'm facing a problem. I'm european so I need to use special characters like á, ã, ç , etc a lot. Is there any other way I can do that without using the corresponding code for each letter every time I need to use one? Like a code I can put in the beggining of the html document or something like that that would make all the special characters accepted. 回答1: Decide which encoding you want to use for your site; if you don't have any preference,

问题 I have a UILabel with some text, say "Hello World abcdefg" The label can have multiple lines, different font sizes etc. Question : How do I find the coordinates of all letters "d" in this UILabel. Logical first step is find the position of those characters in the string (UILabel.text), but then how do I translate that into coordinates when it's actually drawn on screen The idea is to find those coordinates and draw something custom on top of that character (basically to cover it with a custom

问题 I have a problem trying to set a route in Node JS with Express framework. My route is this one: app.get('/campaña/nueva', sms.nueva); But i cant get it to work, because of the evil "Ñ" (it works with an "N" tho) I used codeigniter for a while, and you can set what characters you want to enable or disable Do you guys knows of any workarround or way to enable it in node? 回答1: I think you'll need to handle both a URL-encoded and perhaps a UTF-8 (and possibly Latin-1 also) variant. Check the

问题 I'm 90% sure there is a built in function that does this. I need to find the position of a character in an alphabet. So the character "b" is position 1 (counting from 0), etc. Does anyone know what the function is called? Thanks in advance! EDIT: What i'm trying to do is to send all the characters X amount of "steps" back in the alpha bet, so if i have a string with "hi" it would be "gh" if i sent it back one step. There might be a better way of doing it, any tips? 回答1: It is called index .
