  • 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.

  • Conditional Validation with Paperclip difficult

    - by Michael Schmitz
    Hi, I have an "item", which goes through a multi-page creation process. Images are uploaded at step five, and I keep track of the steps by using the attribute "complete". When validating whether an image is attached with paperclip, I get problems using the code below: validates_attachment_presence :pic1, :if => Proc.new { |u| u.complete == "step5"} It seems that I can't access the "complete" attribute, as the active-record object seems to be the paperclip image. Is there a way for me to check at which point in the process I am and validate conditionally? Thanks, Michael

  • Using IDataErrorInfo and setting Validation.HasError style

    - by Gaurav
    In WPF using IDataErrorInfo and Style I want to create form where I can provide end user three different status while validating data To make the scenario more clear 1) I have textbox next to it I have icon which provides end user what kind of input textbox expects - Initial status with information icon 2) As soon as user enter data it validates it and decides whether it is valid or not - most of the time it will show cross (X) icon saying invalid data 3) As it is validating on UpdateSourceTrigger="PropertyChanged" it will turn cross icon to green check mark as soon as it gets validated i.e [ ] i (tooltip- Any valid user name ) [Ga ] X (tooltip- Invalid user name. Must be 5 char long) [Gaurav ] * (it will show only correct icon, meaning valid value) How can I achieve this using IDataErrorInfo and Style, I tried doing that but as soon as my form gets loaded it invalidates all the data and shows cross icon at the first time. I want to show different tooltip and different icon for three states (Initial info, Invalid data, Valid data)

  • JQuery timer plugin on ASP.NET MVC Page button click

    - by Rita
    Hi I have an ASP.NET MVC Page with a button called "Start Live Meeting". When the User clicks on this button, it calls a controller method called "StartLiveMeeting" that returns a string. If the controller returns empty string, then i want the Timer to call the Controller method until it returns the string. I am using jquery.timer.js plugin ( http://plugins.jquery.com/files/jquery.timers-1.2.js.txt ) On the button click, the controller method is being called. But Timer is not initiating. I have specified 5sec to call the controller method. I appreciate your responses. Code on ASPX Page: //When "Start Meeting" button is clicked, if it doesn’t return empty string, Display that text and Stop Timer. Else call the Timer in every 5 sec and call the StartLiveMeeting Controller method. $("#btnStartMeeting").click(function() { var lM = loadLiveMeeting(); if (lM == "") { $("#btnStartMeeting").oneTime("5s", function() { }); } else { $("#btnStartMeeting").stopTime("hide"); } return false; }); function loadLiveMeeting() { $("#divConnectToLive").load('<%= Url.Action("StartLiveMeeting") %>', {}, function(responseText, status) { return responseText; }); } <asp:Content ID="Content2" ContentPlaceHolderID="cphMain" runat="server"> <div id="divStartMeetingButton"><input id="btnStartMeeting" type="submit" value="Start Meeting" /> </div> <div id = "divConnectToLive"> <div id="loading" style="visibility:hidden"> <img src="../../img/MedInfo/ajax_Connecting.gif" alt="Loading..." /> </div> </div> Controller Method: [HttpPost] public string StartLiveMeeting() { int intCM_Id = ((CustomerMaster)Session["CurrentUser"]).CM_Id ; var activeMeetingReq = (from m in miEntity.MeetingRequest where m.CustomerMaster.CM_Id == intCM_Id && m.Active == true select m); if (activeMeetingReq.Count() > 0) { MeetingRequest meetingReq = activeMeetingReq.First(); return "<a href='" + meetingReq.URI + "'>" + "Connect to Live Meeting</a>"; } else { return ""; } }

  • [jQuery] JSON response is null, but the URL is echoing correctly.

    - by b. e. hollenbeck
    I have a form being AJAX'd in by jQuery on a page with multiple forms. I'm performing the following function, which is a wrapper for the $.ajax function: function do_json_get(uri){ var ret = ''; var url = AJAX_URL + uri; $.ajax({ type: 'GET', url: url, async: false, success: function(data) { ret = data.html; }, dataType: 'json' }); return ret; } When I go to the AJAX server directly (which is rendering the form in PHP), I get the raw JSON response - so I know the server is outputting to the browser, and the AJAX server is doing other things like setting the proper cookies, so I know that the connection is good (I get a 200 response code). Yet the data object is coming back null. What else could I be missing?

    Hello, I've seen around the web the following regex (?=^.{8,}$)((?=.*\d)|(?=.*\W+))(?![.\n])(?=.*[A-Z])(?=.*[a-z]).*$ which validates only if the string: * contain at least (1) upper case letter * contain at least (1) lower case letter * contain at least (1) number or special character * contain at least (8) characters in length I'd like to know how to convert this regex so that it checks the string to * contain at least (2) upper case letter * contain at least (2) lower case letter * contain at least (2) digits * contain at least (2) special character * contain at least (8) characters in length well if it contains at least 2 upper,lower,digits and special chars then I wouldn't need the 8 characters length. special characters include: `~!@#$%^&*()_-+=[]\|{};:'".,/<? thanks in advance.

    - by fusion
    i'm not very well-versed with javascript, so please bear with me. i've a form in which i validate the controls with javascript. the error is displayed when the fields are empty via a div, but when i focus and type something in the textbox, the div should go away. but the error div doesn't and even if i type something valid, it still displays the div. i'd like to know where am i going wrong with this script: <script type="text/javascript"> var err = document.getElementById("errmsg"); function checkInput(inPut) { if (inPut.getValue() == "") { err.setStyle('display', 'block'); err.setTextValue("Field cannot be empty!"); inPut.focus(); return false; } else { return true; } } function checkTextBox(textBox) { if (textBox.getValue() == "") { err.setStyle('display', 'block'); err.setTextValue("Field cannot be empty!"); textBox.focus(); return false; } else if (!checkValidity(textBox.getValue())) { err.setStyle('display', 'block'); err.setTextValue("Please enter a valid email address!"); textBox.focus(); return false; } else { return true; } } . . . <div id="errmsg" class="invalid" style="display:none;"></div> <br /> . . . <input type="text" tabindex="1" name="name" id="name" class="input_contact" onblur="checkInput(this);"/> <br /> . . . <input type="text" tabindex="2" name="email" id="email" class="input_contact" onblur="checkTextBox(this);"/> <br /> it's a form in facebook app but while the fbjs works, i assume there's a problem with my basic javascript.

  • Validation of user input or ?????????

    - by zaf
    We're letting users search a database from a single text input and I'm having difficulties in filtering some user supplied strings. For example, if the user submits: ????????? lcd SONY (Note the ?'s) I need to cancel the search. I include the base64 encoded version of the above string wrapped up so that its easy run: print(base64_decode("1MfLxc/RwdPHIGxjZCBTT05Z")); I've ignored such inputs before but now (am not sure why) just realised the mysql database query is taking nearly forever to execute so this is now on high priority. Another example to highlight that we are using utf-8 and mb_detect_encoding is not helping much: print(base64_decode("zqDOm8+Fzr3PhM63z4HOuc6/IM+Bzr/Phc+HzyU=")); ????t???? ?????% So: how can I detect/filter these inputs? how is this input being generated?

  • XML Validation in ASP.NET MVC during load

    - by Jamie Nordmeyer
    I'm writing an ASP.NET MVC 2 application where one of the backing stores I plan to support is XML. I have a POCO that represents the settings for the site, along with an XML file to contain these settings. My question is what is the best way to validate this data as it is read from disk in to the POCO? I know I can use an XSD, or maybe use the Data Annotations library to mark up the POCO, and use reflection to validate the data, but is there another way, perhaps in .NET 3.5 or MVC to do this? I've spent some time Googling this issue, and want to be sure I'm doing it in the best manner. Thanks in advance!

  • Speed up dialog/page transitions in jQuery Mobile on iPhone?

    - by Crashalot
    There are other SO questions on speeding up jQuery Mobile for Android, but does anyone know how to accelerate page transitions on iPhones, specifically dialog transitions? We're on JQM 1.0. JQM 1.1 is supposed to speed up page transitions (though we haven't seen any demos yet), but we're wondering if anyone has done anything for JQM 1.0. Right now, there is a two second delay, which is too much to show a dialog. We resort to one of two options. Using no animation for the page transition, which provides instant feedback, or rolling our own by binding to "touchstart" and animating the dialog, which is really just a big DIV inside the current page. Neither is ideal. Suggestions?

  • how to autocenter jquery ui dialog whenb resizing browser?

    - by Jorre
    When you use jquery UI dialog, all works well, except for one thing. When the browser is resized, the dialog just stays in it's initial position which can be really annoying. You can test it out on: http://jqueryui.com/demos/dialog/ Click on the "modal dialog" example and resize your browser. I'd love to be able to let dialogs autocenter when the browser resizes. Can this be done in an efficient way for all my dialogs in my app? Thanks a lot!

  • How do you change the style of cell in a JQuery.DataTable?

    - by Sephrial
    Hello fellow coders, I have a question about setting the style attributes for a data cell in the jQuery.DataTable. I was able to set the width for each column when initializing the dataTable using the following: oTable = $('#example').dataTable( { "aoColumns" : [ { sWidth: '40%' }, { sWidth: '60%' } ] } ); However, now I want to change the alignment for the second column like so: style="text-align: right;". I am adding rows dynamically: /* Global var for counter */ var giCount = 2; function fnClickAddRow() { oTable.fnAddData( [ 'col_1', 'col_2' ] ); giCount++; } Can you tell me how I can select the second cell of the added row after it's inserted? OR can you tell me how to set the style of the row before/during insertion? Any help would be greatly appreciated!
