I heard from someone that the maximum array size in .NET is 4 GB? Just wondering if that is true. You wouldn't dream of doing this on 32-bit .NET but on a 64-bit system with 12 GB of RAM, maybe, just maybe you might want to do this. :-) ...
I'm using JPA (Hibernate) and jTDS as my jdbc driver. Whenever the datatype of my entity columns are String, the created prepared statement uses varchar(8000) as its parameter. I've already tried to use @Column(length=50) in my mappings for example, but it seems to be ignored. If I set sendStringParametersAsUnicode in jTDS connection, i...
I'm trying to declare a long value in Java, which unfortunately does not work. This is my code. It results in the following error message: "The literal 4294967296 of type int is out of range". long bytes = 4294967296; I need this value to make a file filter that filters out files that are bigger than 4294967296 bytes (4GB). The other...
Bit of a bizarre question, but does anyone know the actual limit to the length of a webpage, and why it is the limit? As an experiment, I'm using HTML and CSS to make a site that represents a journey to a scale of 1:1. I have a ul list of markers along the way that I have separated with large margins in the css. However, the longest mar...

I'm making a bookmarklet, but I've encountered some wierd behaviour in IE8. The code causing the problem is this: var els = document.getElementById("my_id").getElementsByTagName("*"); for(var i in els) { alert(i+","+els[i]) } The first thing that is alerted is "length, n". This isn't the case in chrome: just in IE8. Interestingly...
Could someone explain this (strange) behavior? Why is the length in the first example 3 and not 2, and most importantly, why is the length in the second example 0? As long as the keys are numerical, length works. When they are not, length is 0. How can I get the correct length from the second example? Thank you. a = []; a["1"] = {"strin...

I'm confused by how the length of a string is calculated when expandtabs is used. I thought expandtabs replaces tabs with the appropriate number of spaces (with the default number of spaces per tab being 8). However, when I ran the commands using strings of varying lengths and varying numbers of tabs, the length calculation was different...

It works, but I'm trying to also make it so that it's only enabled if there's at least one character in the field. I tried wrapping it in: if($(this).val().length > 1) { } But, that didn't seem to work... Any ideas? $("#fbss").f...
I want to make a program in C++ that reads a file where each field will have a number before it that indicates how long it is. The problem is I read every record in object of a class; how do I make the attributes of the class dynamic? For example if the field is "john" it will read it in a 4 char array. I don't want to make an array o...
