  • Batch File input validation - Make sure user entered an integer

    - by B2Ben
    I'm experimenting with a DOS batch file to perform a simple operation which requires the user to enter a non-negative integer. I'm using simple batch-file techniques to get user input: @ECHO OFF SET /P UserInput=Please Enter a Number: The user can enter any text they want here, so I would like to add some routine to make sure what the user entered was a valid number. That is... they entered at least one character, and every character is a number from 0 to 9. I'd like something I can feed the UserInput into. At the end of the routine would be like an if/then that would run different statements based on whether or not it was actually a valid number. I've experimented with loops and substrings and such, but my knowledge and understanding is still slim... so any help would be appreciated. I could build an executable, and I know there are nicer ways to do things than batch files, but at least for this task I'm trying to keep it simple by using a batch file.

  • jquery input-validation (number characters and decimal places).

    - by Cesar Lopez
    I have several javascript functions to validate the input data in textbox, so it will limit the user to type into the textbox a range of numbers (eg. from 0 to 500) an x amount of decimals (eg. 1 or 2 or 3 ....). I am having some issues with the javascript functions because they are three separate functions and the alerts get a bit mixed up. I was wondering if there is a jquery function that will make it neat, effective and simple. Thanks.

  • masked input: I can't get the simplest completion to work

    - by Karl Messner
    Trying to use Josh Bush's masked input plugin. I want to shift focus and do other things once the person puts their cell phone in. I mask to a phone shape. When I hit the last letter, I want it to trigger a javascript function. Right now that function just alerts hi. But I can't get it to work: function jump(){ alert('hi'); } $(document).ready(function(){ $("#cellphone").focus(); jQuery(function($){ $("#product").mask("(999) 999-9999",{completed:function(){jump();}}); }); });

    I want to read from stdin five numbers entered as follows: 3, 4, 5, 1, 8 into seperate variables a,b,c,d & e. How do I do this in python? I tried this: import string a=input() b=a.split(', ') for two integers, but it does not work.

Then?

  • Tracking graphics tablet input in C#

    - by Martin
    I'm writing an XNA application with C#, and I want to be able to control the application with a graphics tablet. All I need to be able to do is track the position and pressure of the pen on the tablet, it would be nice to have some built in gesture recognition but I'm willing to build that myself if needed. My first attempt at this was to use the vbtablet library. However, when I sent this to a friend it failed to work. It seems that the underlying technology is quite old and not supported by some tablets. My second attempt is to play with the Microsoft.Ink system. This looks promising, but I know very little about this subject and I'm struggling to make it work properly - for example I can't find how to read the raw tablet input and disable mouse pointer mode on the tablet when using an InkOverlay. What's the best system to use and what good documentation is there for a beginner in this field?

  • Default Values in XForms Input

    - by Josh
    I have an XForm that has certain fields that may often be left blank (optional street address). Is there is technique to set a default value for that field, preferably a space (I am running into weird formatting issues with CSS). The html form way of value="" doesn't work, neither does setting a default value in the XML schema. EXAMPLE: <xforms:input ref="clientaddress/streetaddress2" model="model_inventory" > <xforms:label>Street Address (Line 2)</xforms:label> Leaving this field blank results in <streetaddress2/> in the resulting xml document I want <streetaddress> </streetaddress>

  • Best Practice - Validating Input In Simple GUI Application?

    - by Alex
    I'm writing a GUI app with wxwidgets in C++ for one of my programming classes. We have to validate input and throw custom exceptions if it doesn't meet certain conditions. My question is, what is best practice when it comes to this? Should I write a seperate function that checks for errors, and have my event handler's call that function? Or should I do my error-checking in my event handlers? Or does it really matter? Thanks!

  • C++ input chaining in C#

    - by Monty
    I am trying to learn C# coming from C++. I am writing just some basic console stuff to get a feel for it and was wondering if it is possible to do simple chaining of inputs in C#. For example in C++: cout<<"Enter two numbers: "; cin >> int1 >> int2; You could then just input 3 5 and hit enter and the values will be fine. In C# however I have to split it up(as far as I can tell) like this: Console.Write("Enter the first number: "; int1 = (char)Console.Read(); Console.Writeline(""); Console.Write("Enter the second number: "; int2 = (char)Console.Read(); Maybe I am just missing something.

  • jQuery Date Picker where text input is read only

    - by Rowan Parker
    Hi all, I want to use the Jquery datepicker. I've got it setup using an the alt field option. I'm displaying Y-M-D in the text field, but submitting Y-M-D. Everything works fine so far, sending the correct data, etc. However I want to stop the user from being able to manually type a date. I add originally set the INPUT field to disabled, which worked in every browser except IE. In IE it would popup the date picker but then not close after clicking a date. Does anyone know the best way to do this?

  • Batch file: Extracting substring from input parameter to use in IF statement

    - by Neomoon
    This is a very basic example of what I am trying to implement in a more complex batch file. I would like to extract a substring from an input parameter (%1) and branch based on if the substring was found or not. @echo off SETLOCAL enableextensions enabledelayedexpansion SET _testvariable=%1 SET _testvariable=%_testvariable:~4,3% ECHO %_testvariable% IF %_testvariable%=act CALL :SOME IF NOT %_testvariable%=act CALL :ACTION :SOME ECHO Substring found GOTO :END :ACTION ECHO Substring not found GOTO :END ENDLOCAL :END This is what my ouput looks like: C:\>test someaction act =act was unexpected at this time. If possible I would like to turn this in to a IF/ELSE statement and evaluate directly from %1. However I have not had success with either.

  • C# / Filter input of a textbox and display notification balloon

    - by asmo
    I'm wondering how to filter the input of a .NET textbox. I already know that I could listen for the KeyDown event and intercept the key, but that won't filter pasted strings by a right-click menu or a CTRL+V. I also don't wan't to completely disable the possibility of pasting of characters in the textbox. The paste action should be cancelled whenever it contains one or more invalid characters. Finally, I'd like to display a notification balloon whenever invalid characters are either entered or pasted. µTorrent already has this exact behavior: How can I achieve this functionality in C# ?

  • ASP.NET TextBox verses input type="text" behavior

    - by harrije
    I notice with ASP.NET if the server side control TextBox is used with out autopostback it will not submit (or postback) the form when typed text ends with enter, which is different from the behavior for plain old HTML pages. Fine, I can set autopostback to get the behavior I want after the enter key. However, autopostback will also cause submit (or postback) when the typed text does not end with enter but focus has changed (i.e. with tab or mouse click), which again is different from plain old HTML pages. How can I get an ASP.NET page to behave the same as a plain old HTML page with respect to text input regardless of whether enter key or change of focus occurs?

  • iPhone Input with Stacked Views

    - by Forrest
    Hi, I've got a situation in an iphone application where buttons are not receiving input as I expect. Here's the setup: ViewMain - The main view full of various images and labels ViewOverlay - A HUD like overlay view with two UIButton objects. To create my scene I do the following: viewController.view = ViewMain [ViewMain addsubview:ViewOverlay] This view renders as expected, with ViewOverlay correctly rendered ontop of ViewMain. However the two buttons found inside ViewOverlay do not receive touch events and can not be pressed. Tapping them does nothing at all. I very well may be going about this in the entirely wrong direction. Any ideas?

  • Is it safe to display user input as input values without sanitation?

    - by Svish
    Say we have a form where the user types in various info. We validate the info, and find that something is wrong. A field is missing, invalid email, et cetera. When displaying the form to the user again I of course don't want him to have to type in everything again so I want to populate the input fields. Is it safe to do this without sanitation? If not, what is the minimum sanitation that should be done first? And to clearify: It would of course be sanitized before being for example added to a database or displayed elsewhere on the site.

  • How to detect if a form input element of type file is empty

    - by Ankur
    I have some code which reads a file through a form field of type file <input type="file" ... /> I want to give the user another option of providing a url to a file rather than having to upload it as many are already online. How can I detect when this field is empty on the server side. I am using Apache Commons FileUpload FileItemStream item = iter.next(); name = item.getFieldName(); stream = item.openStream(); if(!item.isFormField()){ if(item.toString()!=""){ .... I need to detect when item is empty. The above code doesn't work, nor does using: if(item.equals(null)){ ....

  • c++ strings and file input

    - by Dalton Conley
    Ok, its been a while since I've done any file input or string manipulation but what I'm attempting to do is as follows while(infile >> word) { for(int i = 0; i < word.length(); i++) { if(word[i] == '\n') { cout << "Found a new line" << endl; lineNumber++; } if(!isalpha(word[i])) { word.erase(i); } if(islower(word[i])) word[i] = toupper(word[i]); } } Now I assume this is not working because skips the new line character?? If so, whats a better way to do this.

  • CSS bug in text input field - MSIE7

    - by Uri Bruck
    I have an input text in a form that has a problem in MSIE7. When the text field is filled and I continue typing, the background starts scrolling left along with the text. This is the form when the text field is filled http://img155.imageshack.us/i/screen2rl.jpg/ The background image, a white rectangle with rounded corners, scrolls left with the text, leaving the black background. This is the CSS for this text field: border: none; background: url('/wp-content/themes/pokerbuddy/images/field.png') top left no-repeat; width: 100px; height: 20px; padding: 0px; font-size: 80%; color: #399; display:inline; Is there any way to solve this in MSIE7?

  • Flex Application for PlayBook Text Input Variable

    - by user568128
    I know this is probably a very simple question, but can someone please walk me through how to take what a user inputs into a s:TextInput and use that as a variable in a JSON data request? Basically, I want to have a user enter a search term, like "math" and then have that placed into a variable so I can use it in a JSON request. Something like public var q:String, except that my search box (and hence user input) is on another "view" of the application. I've just started with Flex Mobile applications and I might be way out of my league. Does anyone know how to do this?

  • Best way to set a default button (or trigger its event in javascript) for an input field, not part of a form

    - by Sheldon Pinkman
    I've got a stand-alone input field, not part of any form. I also got a button, that has some onclick event. When I type something in the input field, and press the Enter key, I want it do effectively press the button, or trigger its onclick event. So that the button is "the input field's default button" so to speak. <input id='myText' type='text' /> <button id='myButton' onclick='DoSomething()'>Do it!</button> I guess I can mess around with the input field's onkeypress or onkeydown events and check for the Enter key, etc. But is there a more 'clean' way, I mean something that associated the button with that input field, so that the button is the 'default action' or something for that field? Note that I'm not inside a form, I am not sending, posting, or submitting something. The DoSomething() function just changes some of the HTML content locally, depending on the text input.

  • JQuery plugin: catch events for clicking/tabbing into and out of an input box

    - by poswald
    I'm creating a Javascript JQuery Timepicker control plugin (which I hope to open source soon) and I would like some advice on how to best register the events in the cleanest way. The control will attach to an <input> box and provide a graphical way to enter times of day ( 14:25, 2:45 AM, etc...). It does this by adding a <div> after the input box. What I want is to bind an openControl() function that fires when the input is clicked or tabbed to, and a closeControl() function that fires when the input box is tabbed away from or deselected but not if the control itself is clicked. That is, I don't want to close the control if you're clicking inside of the control's <input> or the <div>. Here's what I have been doing to try to get there: /* Close the control attached to the passed inputNode */ function closeContainer(inputNode, options) { $input = $(inputNode); if ( $input.next().is(':visible')) { $input.next().hide(options.hideAnim, options.hideOptions, options.hideDuration, options.onHide ); } } /* Open the control */ function openContainer(node, options) { $input = $(node); $input.next().show(options.showAnim, options.showOptions, options.showDuration, options.onShow ); // bind a click handler for closing the contol $("body").bind('click', function (e) { $('.time-control').each( function () { $input = $(this).prev(); // only close if click is outside of the control or the input box if (jQuery.contains(this, e.target) || ($input.get(0) === e.target) ) { closeContainer($input, options); setTime($input, $input.next(), options); } else { closeContainer($input, options); } }); }); } I want to add support for tabbing in/out but I feel like this approach is wrong. Focus/Blur wasn't working well because the blur event fires if you click on the control. Should I be using those events but filtering out if they are inside the control's div? Anyone have a better way of doing this? Thanks!

NTFS is inconsistent. Run chkdsk /f on Windows then reboot it TWICE! The usage of the /f parameter is very IMPORTANT! No modification was and will be made to NTFS by this software until it gets repaired. I don't have windows installed, how can I run chkdsk /f from ubuntu?

  • Design of input files reading when it comes to defaults/transformations

    - by Stefano Borini
    Suppose you have an application that reads an input file, on a language that does not support the concept of None. The input is read, parsed, and the contents are stored on a structure for later use. Now, in general you want to keep into account transformation of the data from the input, such as adding default values when not specified, or adding full path information to relative path specified in the input. There are two different strategies to achieve this. The first strategy is to perform these transformations at input file reading time. In practice, you put all the intelligence into the input parser, and your application has no logic to deal with unexpected circumstances, such as an unspecified value. You lose the information of what was specified and what wasn't, but you gain in black-boxing the details. Your "running code" needs that information in any case and in a proper form, and is not concerned if it's the default or a user-specified information. The second strategy is to have the file reader a real one-to-one mapper from the file to a memory-stored object, with no intelligent behavior. unspecified values are not filled (which may however be a problem in languages not supporting None) and data is stored verbatim from the file. The intelligence for recovery must now go into the "running code", which must check what was specified in the file, eventually fall back to a default, or modify the input properly before using it. I would like to know your opinion on these two approaches, and in particular which one you found the most frequently implemented.
