maxlength

问题 I need to open a text file with ~4MB in a RichTextBox, but the end of the text was "trimmed". How do I override a RichTextBox.MaxLength Int32 limit? 回答1: I'm not sure how much text RichTextBox can handle, but I believe MaxLength only applies to text the user enters. If you set .Text directly it should be able to go past MaxLength, unless MaxLength is already at the maximum. 回答2: The default for RichTextBox.MaxLength is 2GB, so with a 4MB file this is not going to be your problem. 回答3: Besides

问题 I have a textbox for Age: <input type="text" id="txtAge" name="txtAge" class="text" placeholder="Age (optional)" maxlength="2"> Upon clicking submit, this input is instantly bordered red. There is no postback. I'm assuming IE10 believes the client has actually typed in "Age (optional)" which is greater than the maxlength of 2. Is there anyway to get around this without making the user do anything in their browser's settings and without removing the maxlength attribute? 回答1: You can use the

问题 In jsDoc I can specify my array parameters and members like this: /** * @constructor * @param {Array.<string>} myArray */ function someFunction( myArray ){ this.firstArray = myArray; /** @member {Array.<float>} */ this.secondArray = []; } Is there also a way to specify the length , or minLength and maxLength of these arrays? 回答1: I think you're asking whether you can include the minimum/maximum length in the type expressions (for example, Array.<string> ). In short, the answer is no. You'll

问题 First things first: I'm storing multiple domains to a database, after I've converted each and every domain name to it's IDNA version. What I need to know the maximum length such an IDNA-converted domain name can have so I can define the database field's max length. Known fact: Now, I know the maximum number of characters in a domain name (including any subdomains) is 255 characters. Where I lost it: That's easy at first glance, but... does this mean regular ascii characters of international

问题 As part of my probably wrong and cumbersome solution to print out a form I have taken a MS-Word document, saved as XML and I'm trying to store that XML as a groovy string so that I can ${fillOutTheFormProgrammatically} However, with MS-Word documents being as large as they are, the String is 113100 unicode characters and Groovy says its limited to 65536. Is there some way to change this or am I stuck with splitting up the string? Groovy - need to make a printable form That's what I'm trying

问题 I am attempting to bind a WPF textbox's Maxlength property to a known constant deep within a class. I am using c#. The class has a structure not too dissimilar to the following: namespace Blah { public partial class One { public partial class Two { public string MyBindingValue { get; set; } public static class MetaData { public static class Sizes { public const int Length1 = 10; public const int Length2 = 20; } } } } } Yes it is deeply nested, but unfortunately in this instance I can't move

问题 How can I limit the length of <h:inputTextarea> ? For <h:inputText> it works fine with maxlength attribute. However, this attribute is unavailable in <h:inputTextarea> . 回答1: HTML5 + JSF 2.2+ If you're using HTML5 and JSF 2.2+, specify it as a passthrough attribute. <html ... xmlns:a="http://xmlns.jcp.org/jsf/passthrough"> <h:inputTextarea value="#{bean.text}" a:maxlength="2000" /> HTML5 + JSF 2.0/2.1 If you're using HTML5, but not JSF 2.2 yet, use OmniFaces Html5RenderKit to recognize new

问题 Here is an example: $(function() { $('#test').change(function() { $('#length').html($('#test').val().length) }) }) <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <textarea id=test maxlength=10></textarea> length = <span id=length>0</span> Fill textarea with lines (one character at one line) until browser allows. When you finish, leave textarea, and js code will calculate characters too. So in my case I could enter only 7 characters (including
