How to read from input file (text file) and validate input as valid integer?
I would probably read the line with std::getline, then use a Boost lexical_cast to convert to int. It will throw an exception unless the entirety of the input string can be converted to the target type -- exactly what you want. Of course, you'll also need to check that the converted result is in the correct range, and also throw the exception if it's out of range.

Validate input fields after changing input values with jQuery or echoing values with PHP
Dynamically created DOM objects cannot be selected with javascript directly. You need to select a static element that existed before any DOM manipulation. Here's an example: $(document).ready(function(){ $("body :input, select").each(function() { if(!$(this).val() === "") $(this).valid(); }); }); body element is static (not created) by javascript and so can be selected. From tehre you can navigate to any element as normal. You also do not need to use body. Any element that is static html or created by back-end programming language will work. Alternatively you could use liveQuery plugin for jQuery.

2 input but validate only one
You need two different forms, one for Add Project and one for Edit Project. These need to point to different actions, which will then only validate one object. Im not sure what your code looks like but I would really suggest something more like the following, where your views are separated entirely: Start with a view that displays all of your 'Products' or whatever your data is. When you populate this in your view, you can then assign Edit links to each individual one. You only need one overall Add Project link. Like so: @Html.ActionLink("Add Project", "AddProjectView") For Each project In Model.Projects @Html.ActionLink("Edit", "EditView", New With {.id = project.ProjectID}) @<div>PropertyName: @Project.Property</div> Next Now you can have an Edit view separated f

How to validate this xml input?
There are lots of schema generators on-line. I use them to get me started with a new XML document, creating a basic schema that focuses on the position of elements. This saves me a lot of time. Once it's working I start adding the individual field restrictions. One final tip. Use an editor that enables you to format your XML. Schemas are difficult to read at the best of times :-( Schema Generators Here's your example generated by Freeformatter.com <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="users"> <xs:complexType> <xs:sequence> <xs:element name="user" maxOccurs="unbounded" minOccurs="0"> <xs:complexType> <xs:se

How can I validate input so that it must be an integer
You should first get the user input, then try to parse it as integer, if it fails (raises ValueError) then print an error message, and if it's a valid integer then check the range and do whatever you want. value = input('Enter minutes :') try: value = int(value) if 4 < value < 61: # Do your stuff else: print('Error value must be in range: 5-60') except ValueError: print('The value you entered is not a valid integer value')

Validate input for the following condition
You are checking your conditions the other way round. Invert the signs and you will be good. Like: if(k<=10.0 || k>=100.0) //if(k<10.0 || k>100.0) If you want to include 10 and 100 printf("invalid input range"); Or to simplify your program do { scanf("%f",&k); }while(k<=10.0 || k>=100.0);

Proper way to validate an input
With validation efficiency is not usually the concern. There are two types of validation that you should be concerned with: Input validation, e.g. will what the user is sending to the server malicious and intended to break/break into my application Business validation, which should happen in your business logic, and should be about maintaining valid, consistent values. Skipping over either of these is a very very good way to end up with either a hacked or badly broken application. If you're using ASP.net there are a plethora of libraries (mostly from Microsoft) to do the former, Anti-XSS lib etc. The latter would be most efficiently preformed in your shared business logic in the entities themselves. E.G your user entity should not allow an age of -1.

How does AWT process input so i can validate it
AWT is not meant to be intercepted by Java code. However your idea of looking at input methods was the right direction. Here is an example class that will filter simple insertions of 'a' chars out of the events going to the text field. It might serve as a starting point. import java.awt.*; import java.awt.event.KeyEvent; import java.awt.im.InputContext; import java.lang.Character.Subset; import java.util.Locale; class SpecialTextField extends TextField { InputContext customIC=new InputContext() { @Override public void dispatchEvent(AWTEvent event) { if(event.getID()==KeyEvent.KEY_TYPED) { KeyEvent ev=(KeyEvent)event; if(ev.getKeyChar()=='a') { ev.consume(); return; } } SpecialTextField.super.get

How can I validate input does not contain specific words?

JSP input validate amount - possibly with REGEX

This expression kills them, except for 0 in the one's column. Works with or without commas and/or dollar sign. Decimals not mandatory, unless no zero in ones column and decimal point is placed. Allows $0.00 and .0 Keywords: money dollar currency E.g., $1,234.50 | $0.70 | .7

SSRS Validate User Input Length
Step 1: Use report designer or VS and set the parameter type to int; this will ensure that only integers are accepted. Step 2: Option 1: Create a 2nd dataset that accepts the inital parameter as input and queries the datasource for a valid employee id. If there is no match, you could return an "invalid employee #" type message. If there is a match, use the returned value as a parameter for the main query. Option 2: Use the Code section of report builder to return a true/false boolean based on the length of the initial supplied parameter. Something like this (this is untested because I'm not a VB developer): 1: 'Invalidates the duration between the start date and end date 2: Function ValidateParam(Parameter) as Boolean 3: If LEN(CSTR(Parameter)) = 16 Then 5: Ret

You can declare String pin as a field like: String pin; then in action performed you append to it (pseudo code) actionPerformed(...){ pin += keyPressed; if(pin.length > 5){ validatePin(pin); } } Does this answer your question? But to be honest I would suggest against validation in the action performed method. I'd try to validate the pin after all the numbers were inserted. This way you can save a bit on performance and the code would be more readable. The performance isn't an issue here but it's a good practice as you would check the pin 6 times here instead of just once outside the actionPerformed method. Like: for(int i = 0; i < pinLength; i++){ waitForUserToPressButtonOrTimeout(); appendToCurrentPin(); } validatePin(); Or let the user simply

How do I Validate If input type text isn't empty - PHP

OR method: if($nml<1 || $eml<1 || $msgl<1) { exit(/* simplified for clarity */); } If each message needs to be different, then separate if statements, like so: if($nml<1) { exit(/* simplified for clarity */); } if($eml<1) { exit(/* simplified for clarity */); } if($msgl<1) { exit(/* s

jQuery Validate array input element which is created dynamically
Regarding your code for creating the new fields: // Mode 1 $("#addInput").on('click', function () { $('#inputs').append($('<input class="comment" name="name[]" />')); }); The entire reason your "Mode 1" was not working is because you've assigned the same exact name attribute, name="name[]", to every single new input. The jQuery Validate plugin absolutely requires that every input element have a unique name attribute. Just use your numberIncr variable within name[] to ensure this unique name. Also, you really should not be adding rules upon submit. The submit event is normally where all the rules are checked, so adding rules at this point does not make a lot of sense. The new rules should be added when the new input fields are created. For your simple case, the rules('add'
