  • Grep and Awk in Windows Invalid Char in Expression Error

    - by Nathan
    I am new to grep and awk - using Windows 7 (I downloaded grep and awk for windows from GnuWin). I am have having trouble running this script: grep -Fwf dictionary.txt frequency.txt | awk '{print $2 "," $1}' I get the error: awk: '{print awk: ^ invalid char ''' in expression I believe it might have something to do with having to use double quotes in Windows, but I tried all the combinations I can think of and still it doesn't work. Can anyone help? Thanks

  • ASP.Net JSON Web Service Post Form Data

    - by Will D
    I have a ASP.NET web service decorated with System.Web.Script.Services.ScriptService() so it can return json formatted data. This much is working for me, but ASP.Net has a requirement that parameters to the web service must be in json in order to get json out. I'm using jquery to run my ajax calls and there doesn't seem to be an easy way to create a nice javascript object from the form elements. I have looked at serialiseArray in the json2 library but it doesn't encode the field names as property name in the object. If you have 2 form elements like this <input type="text" name="namefirst" id="namefirst" value="John"/> <input type="text" name="namelast" id="namelast" value="Doe"/> calling $("form").serialize() will get you the standard query string namefirst=John&namelast=Doe calling JSON.stringify($("form").serializeArray()) will get you the (bulky) json representation [{"name":"namefirst","value":"John"},{"name":"namelast","value":"Doe"}] This will work when passing to the web service but its ugly as you have to have code like this to read it in: Public Class NameValuePair Public name As String Public value As String End Class <WebMethod()> _ Public Function GetQuote(ByVal nvp As NameValuePair()) As String End Function You would also have to wrap that json text inside another object nameed nvp to make the web service happy. Then its more work as all you have is an array of NameValuePair when you want an associative array. I might be kidding myself but i imagined something more elegant when i started this project - more like this Public Class Person Public namefirst As String Public namelast As String End Class which would require the json to look something like this: {"namefirst":"John","namelast":"Doe"} Is there an easy way to do this? Obviously it is simple for a form with two parameters but when you have a very large form concatenating strings gets ugly. Having nested objects would also complicate things The cludge I have settled on for the moment is to use the standard name value pair format stuffed inside a json object. This is compact and fast {"q":"namefirst=John&namelast=Doe"} then have a web method like this on the server that parses the query string into an associate array. <WebMethod()> _ Public Function AjaxForm(ByVal q As String) as string Dim params As NameValueCollection = HttpUtility.ParseQueryString(q) 'do stuff return "Hello" End Sub As far a cludges go this one seems reasonably elegant in terms of amount of code, but my question is: is there a better way? Is there a generally accepted way of passing form data to asp.net web/script services?

  • JavaScript: How to get the instance name of an object

    - by Quandary
    I use the below code to write code to query a web method in a specified interval. now in the this.Poll function I have to do this.tmo = setTimeout(this.strInstanceName + ".Poll()", this.iInterval); instead of this.tmo = setTimeout(this.Poll(), this.iInterval); because IE looses the this object after setTimeout So I have to pass the class it's instance name: var objPoll = new cPoll("objPoll"); How can I get the instance name without passing it as parameter ? I want to have it outta there ! <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>Intervall-Test</title> <script type="text/javascript" language="javascript"> function test() { alert("Test"); test.tmo = setTimeout(test, 2000); test.Clear = function() { clearTimeout(test.tmo); } } function cPoll(strInstanceName) { this.strInstanceName = strInstanceName ; this.iInterval = 2000; this.tmo=null; this.cbFunction=null; alert(this.Name ); this.Poll = function() { this.cbFunction(); this.tmo = setTimeout(this.strInstanceName + ".Poll()", this.iInterval); } this.Start = function(pCallBackFunction, iIntervalParameter) { if(this.tmo != null) this.Stop(); if(iIntervalParameter && iIntervalParameter > 0) this.iInterval=iIntervalParameter; this.cbFunction=pCallBackFunction; if(this.cbFunction!=null) this.Poll(); else alert("Invalid or no callback function specified"); } this.Stop = function() { if(this.tmo != null) { clearTimeout(this.tmo); this.tmo=null; } } } function CallBackFunction() { alert("PollCallBack"); } // test(); // test.Clear(); var objPoll = new cPoll("objPoll"); </script> </head> <body> <h1>Test</h1> <input type="Button" value="Start polling" onclick="objPoll.Start(CallBackFunction,3000);" /> <input type="Button" value="Stop polling" onclick="objPoll.Stop();" /> </body> </html>

  • Drupal Query builder

    I quite often use Drupal's Views Module to build SQL that I paste into my code. It understands the Drupal database schema quite well. Is there a module that would give me this functionality or can I factor this out of Views?

  • Project summary - Source code lines

    - by MartyIX
    I'm looking for a tool that would count the number of files, the number of lines (with or without comments) and possibly other statistics for my project in PHP and JavaScript. Notes: I've already found SLOCCount which seems quite nice. It requires Cygwin. Yes, I can wrote a simple script for basic information but I'm looking for something more complex. Do you know about alternatives for Windows? Thanks!

  • load Javascript object from file

    - by megapool020
    Hi there, I asked a question in this thread Stackoverflow, and it works perfect. So tnx to all the users who gave me a reply. But now I have a other question. I would like to have the object in a seperate file, so I only need to update the file in stead of the JS file (otherwise it will be very big). I'm using JQUERY. I now looks like this (with all the info in the JS file). IBANInfo is used to fill a selectbox var IBANInfo = { "ccAL":{ countryCode:"AL", countryName:"Albani&euml;", IBANlength:"28", bankFormCode:"0 8n 0 ", accountNum:"0 16 0 " }, "ccAD":{ countryCode:"AD", countryName:"Andorra", IBANlength:"24", bankFormCode:"0 4n 4n", accountNum:"0 12 0 " }, "ccBE":{ countryCode:"BE", countryName:"Belgi&euml;", IBANlength:"16", bankFormCode:"0 3n 0 ", accountNum:"0 7n 2n" } }; //---- then this function is used to build the selectList function createSelect(){ var selectList = ''; var key; selectList += "<option value=''>Kies een land</option>\n"; for (key in IBANInfo) { if (IBANInfo.hasOwnProperty(key)) { var countryInfo = IBANInfo[key]; selectList += "<option value='"+countryInfo.countryCode+"'>"+countryInfo.countryName+"</option>\n"; } } $('#selectBox').html(selectList); } I thought I could do it like this, but I get the message undefined in my selectbox. var IBANInfo = $.get('include/countryCodes.txt'); // also tried var IBANInfo = $.getJSON('include/countryCodes.txt'); //---- then this function is used to build the selectList function createSelect(){ var selectList = ''; var key; selectList += "<option value=''>Kies een land</option>\n"; for (key in IBANInfo) { if (IBANInfo.hasOwnProperty(key)) { var countryInfo = IBANInfo[key]; selectList += "<option value='"+countryInfo.countryCode+"'>"+countryInfo.countryName+"</option>\n"; } } $('#selectBox').html(selectList); } /* the countryCodes.txt file is like this: { "ccAL":{ countryCode:"AL", countryName:"Albani&euml;", IBANlength:"28", bankFormCode:"0 8n 0 ", accountNum:"0 16 0 " }, "ccAD":{ countryCode:"AD", countryName:"Andorra", IBANlength:"24", bankFormCode:"0 4n 4n", accountNum:"0 12 0 " }, "ccBE":{ countryCode:"BE", countryName:"Belgi&euml;", IBANlength:"16", bankFormCode:"0 3n 0 ", accountNum:"0 7n 2n" } } */ What am I doing wrong. Tnx in advance

  • How to get a OAuth token for Google Buzz using username and password without showing Googles login p

    - by Witek
    To read Google Buzz activities, an authorization token is required. A web application would redirect to Googles login page, where the user logs in and a token is returned back to the web application. But I have a local Java application without a UI (like a script). This application knows username and password. How to get an authorization token, using this username and password, without presenting the Google login page?

  • javascript select box hanging on second select in ie7

    - by bsandrabr
    I have a drop down select box inside a div. When the user clicks on change, a dropdown box appears next to the change/submit button and the user makes a selection which then updates the db and the selection appears instead of the dropdown. All works fine in IE8 and firefox but in IE7 it allows one selection (there are several identical dropdowns) but the second time a selection is made it hangs on please wait. This is the relevant code <td width=200> <input type="button" onclick="startChanging(this)" value="Change" /></td> <script type="text/javascript"> var selectBox, isEditing = false; var recordvalue; if( window.XMLHttpRequest ) { recordvalue = new XMLHttpRequest(); } else if( window.ActiveXObject ) { try { recordvalue = new ActiveXObject('Microsoft.XMLHTTP'); } catch(e) {} } window.onload = function () { selectBox = document.getElementById('changer'); selectBox.id = ''; selectBox.parentNode.removeChild(selectBox); }; function startChanging(whatButton) { if( isEditing && isEditing != whatButton ) { return; } //no editing of other entries if( isEditing == whatButton ) { changeSelect(whatButton); return; } //this time, act as "submit" isEditing = whatButton; whatButton.value = 'Submit'; var theRow = whatButton.parentNode.parentNode; var stateCell = theRow.cells[3]; //the cell that says "present" stateCell.className = 'editing'; //so you can use CSS to remove the background colour stateCell.replaceChild(selectBox,stateCell.firstChild); //PRESENT is replaced with the select input selectBox.selectedIndex = 0; } function changeSelect(whatButton) { isEditing = true; //don't allow it to be clicked until submission is complete whatButton.value = 'Change'; var stateCell = selectBox.parentNode; var theRow = stateCell.parentNode; var editid = theRow.cells[0].firstChild.firstChild.nodeValue; //text inside the first cell var value = selectBox.firstChild.options[selectBox.firstChild.selectedIndex].value; //the option they chose selectBox.parentNode.replaceChild(document.createTextNode('Please wait...'),selectBox); if( !recordvalue ) { //allow fallback to basic HTTP location.href = 'getupdate.php?id='+editid+'&newvalue='+value; } else { recordvalue.onreadystatechange = function () { if( recordvalue.readyState != 4 ) { return; } if( recordvalue.status >= 300 ) { alert('An error occurred when trying to update'); } isEditing = false; newState = recordvalue.responseText.split("|"); stateCell.className = newState[0]; stateCell.firstChild.nodeValue = newState[1] || 'Server response was not correct'; }; recordvalue.open('GET', "getupdate.php?id="+editid+"&newvalue="+value, true); recordvalue.send(null); } } </script> If anyone has any idea why this is happening I'd be very grateful

  • solve mathematical equation with 1 unknown (equations are dynamically built)

    - by chris-gr
    Hi, I have to built dynamically equations like following: x + x/3 + (x/3)/4 + (x/3/4)/2 = 50 Now I would like to evaluate this equation and get x. The equation is built dynamically. x is the leaf node in a taxonomy, the other 3 nodes are the super concepts. The divisor represents the number of children of the child nodes. Is there a library that allows to build such equations dynamically and resolve x? Thanks, Chris

  • ASP.NET MVC - PartialView html not changing via jQuery html() call

    - by Bryan Roth
    When I change the selection in a DropDownList, a PartialView gets updated via a GET request. When updating the PartialView via the jQuery html() function, the html returned is correct but when it displayed in the browser it is not correct. For example, certain checkboxes within the PartialView should become enabled but they remain disabled even though the html returned says they should be. When I do a view source in the browser the html never gets updated. I'm a little perplexed. Thoughts?
