input length = value length & expands automatically according to value length
by Govind Bhavan in Web Design

I want value length to be the same length as input field and expand automatically. When i write in some text it always has right or left free space. I don't want to define input size, i just want it to be the size of the text.

Can this be done ?

Regular Expression which matches fixed length chunk with variable length elements
by markku in Programming Languages

I'm writing some regex to match lines which contain numeric elements padded with spaces, like -2.45. The regex for this is simple enough:


However, I have the additional constraint that the whole chunk is limited to exactly seven characters. I can modify the expression to constrain the leading space and digits to within their theor

ASP.NET WebForms “Length cannot be less than 0 or exceed input length.” on application startup
by CodeAndLearn in Programming Languages

I'm picking up an old ASP.NET WebForms project, and I'm getting this on startup:

Length cannot be less than 0 or exceed input length. Parameter name:

What's baffling is, my application code is nowhere in the stack trace. Here's what's shown:

[ArgumentOutOfRangeException: Length cannot be less than 0 or exceed input length.

ruby: building string with length constraint composed from many variable length strings
by Mutilator in Programming Languages

I thought I'd throw out this problem to see what elegant solutions folk
could come up with and, in the process, hopefully learn some new ruby

I'll set the problem in the context of producing a twitter message,
which has a maximum length of 140 characters. I'm looking for a concise
function that will deliver a tweet no longer than 140 characters from

Fragmented length prefix causes next data read from buffer use incorrect message length
by cengel4 in Programming Languages

I'm one of those guys who come here to find answers to those questions that others have asked, and I think i newer asked anything myself, but after two days searching unsuccessfully I decided that it's time to ask something myself. So here it is...

I have a TCP server and client written in C#, .NET 4, asynchronous sockets using SocketAsyncEventArgs. I have a length-prefixed message

How to make a given length byte array composed of other given length bytes arrays JAVA
by facebook-opengraph in Java

I want to send a byte Array of 256 byte length, it have to be 128 byte of a string and the same length with another string ( lengths are just for testing purposes).

This is my code:

public void packetCompose(String user, String password) {
//insert user in 128 bytes length, same with password
//and make a 256 length byte array to send

Provided array of length 3 when length 6 was expected for variable 'vVector__1' using Infer.NET
by Skurge in Network & Servers

I'm trying to modify an example from Infer.NET to make it more flexible. I want to be able to send any number of metrics to draw upon for the predictions.

I created the following wrapper class (very close to the original example):

class Inference
private readonly List<List<double>> _pastMetrics = new List<List<double>>();

Binary serialization of variable length data and zero length arrays, is it safe?
by WellBeing in Programming Languages

I did some research but cannot find a definite approval or disapproval.

What I want is, a fixed size structure + variable length part, so that serialization can be expressed in simple and less error prone way.

struct serialized_data
int len;
int type;
char variable_length_text[0];

How to Count String Length & if Greater than X Length Remove X Characters - JavaScript
by Aires in Javascript

I'm trying to determine the length of a string of characters using JavaScript & if that string of characters is greater than X length, remove enough characters to make it X length.

Here is a more specific example:

Lets say I want to count the length of this string of characters:

testing this

I could do something like this:

Length-wise-sorted list but, same length in alphabetical-order in a step
by NikolaeVarius in Programming Languages

My Python List of string is something like x but long enough:

x = ['aaa','ab','aa','c','a','b','ba']

I wants to sort this list as: ['a', 'b', 'c', 'aa', 'ab', 'ba', 'aaa'] and I did as follows in two steps:

>>> x.sort()
>>> x.sort(key=len)
>>> x
['a', 'b', '
