I have an file input tag in my web app. I'd like to check that the file isn't too big before sending it to the server. Of course, I still have validation server side.

I have a form that is accepting URLs from users in PHP. What characters should I allow or disallow? Currently I use $input= preg_replace("/[^a-zA-Z0-9-\?\:#.()\,\/\&\'\\"]/", "", $string); $input=substr($input,0,255); So, it's trimmed to 255 chars and only can include letters, numbers, and ? - _ : # ( ) , & ' " / Anything I should b...

Or alternatively, if the resulting "NOTE: Invalid argument" message can be avoided? data null; format test2 date9.; input test ; test2=INPUT(PUT(test,8.),yymmdd8.); if error =1 then do; error=0; test2=INPUT(PUT(test-1,8.),yymmdd8.); end; put te...
Hi! We're trying to read data from 2 usb mice connected to a linux box (this data is used for odometry/localization on a robot). So we need to continuously read from each mouse how much it moved. The problem is that when a mouse is not moving, it doesn't send any data, so the file stream from which we get the data blocks execution and t...

Is it possible to prevent a user from typing in a file input text box in IE? The reason I ask is that if a user enters text that does not look like a file system path (eg. doesn't start with something like c:...) then when the user clicks the submit button nothing will happen. I would either like to not allow the user to type in the bo...

I have a search form with a number of text inputs & drop downs that submits via a GET. I'd like to have a cleaner search url by removing the empty fields from the querystring when a search is performed. var form = $("form"); var serializedFormStr = form.serialize(); // I'd like to remove inputs where value is '' or '.' here window.l...
Hi, I'm trying to create a system where you can drag and resize divs (jquery ui) and then save the positions and sizes to a css file. I already got the system working with one div, but now that I tried to update the system to support multiple divs, I ran into a problem. The source: http://ezmundorf.110mb.com/problem.txt (It's ugly, but...
So I was feeling bored and decided I wanted to make a hangman game. I did an assignment like this back in high school when I first took C++. But this was before I even too geometry, so unfortunately I didn't do well in any way shape or form in it, and after the semester I trashed everything in a fit of rage. I'm looking to make a txt ...

For example: #include <iostream> int main(void) { int val = 0; std::cout << "Enter an integer: "; std::cin >> val; std::cout...
I am having problems with MVC RC2 where upon validation failure, the failed field will throw a NullReferenceException when the view is passed back to the user. A short term solution was found: which was to rename the Html.ValidationMessage to be different than the Target Form Field. This works! BUT now the automatic highlighting is di...

Hi there, Can someone show me some example for restricting user input (on input tag) in Javascript? Something that when we set the input (type="text") to only accept numeric, so it will ignore any other input except for numeric... I think it's handy for number input (such as zip, credit card, money, value, score, date etc...), and if ...
