//alert(challengeVal);

var reponseVal = Recaptcha.get_response();

alert(reponseVal);

var remoteIp = "172.18.224.92";

//alert(remoteIp);

var privateKey = ’Your_Private_Key’;

var requestUrl = "http://api-verify.recaptcha.net/verify?privatekey=" + privateKey + "&remoteip=" + remoteIp + "&challenge=" + challengeVal + "&response=" + reponseVal;

return requestUrl;

}

script>

<script type="text/javascript">

$(document).ready(function () {

var container = $('#target');

$('.ajaxtrigger').click(function () {

var url = showResult();

doAjax(url);

//return false;

});

function doAjax(url) {

// if it is an external URI

if (url.match('^http')) {

// call YQL

$.getJSON("http://query.yahooapis.com/v1/public/yql?" +

"q=select%20*%20from%20html%20where%20url%3D%22" +

encodeURIComponent(url) +

"%22&format=xml'&callback=?",

// this function gets the data from the successful

// JSON-P call

function (data) {

// if there is data, filter it and render it out

if (data.results[0]) {

var data = filterData(data.results[0]);

container.html(data);

Recaptcha.reload();

// otherwise tell the world that something went wrong

} else {

var errormsg = '

Error: could not load the page.

';

container.html(errormsg);

}

}

);

// if it is not an external URI, use Ajax load()

} else {

$('#target').load(url);

Cannot alter the login 'sa', because it does not exist or you do not have permission.

Working on projects, it can happen that 'sa' account gets locked. If it is on local machine OR development boxes, onus would be on you to fix it. If scripts and SQL steps are not working, this might help you fixing the issue. Steps to unlock 'sa' account and resetting the password. 1. Open SQL Server Configuration Manager 2. Select SQL Server Services -> 'SQL Server' service. 3. Right click on 'SQL Server' service and click on "Startup Parameters". For 2008, server "Startup Parameters" are inside Advanced tab.   4. Add '-m' in startup parameters as shown above and click on 'Add'. This will put SQL server into 'Single User Mode' and local admin will have 'Super User' rights. For 2008, server you have to add ':-m' in the last of the existing query. 5. Save the settings and Restart the service. 6. Now open the SQL Server Management Studio and connect to database using 'Windows A

Could not load file or assembly 'Microsoft.Web.Infrastructure'

Could not load file or assembly 'Microsoft.Web.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. What 'Micorosoft.Web.Infrastructure' does? This dll lets HTTP modules register at run time. Solution to above problem: Copy 'Micorosoft.Web.Infrastructure' dll in bin folder of your project and this problem should be resolved. If you have .Net framework installed on machine, this dll should be present on it. You can search for this dll and copy it in your active project folder.   Alternatively,  you can install this dll using nuget package manager PM> Install-Package Microsoft.Web.Infrastructure -Version 1.0.0 Happy coding!!

Dockerize a dotnet core application with SQL connectivity

Before reading this article, I am assuming that you know Docker, Dotnet core and have a dotnet core application which is trying to connect to SQL server. Read how to build aspnet core app, docker and run the docker container. If docker container is running and you are not able to connect to database, this blog should help you fix it.  Prerequisite -  Make sure code is working via running aspnet core locally via visual studio or command line. Port 1433 is opened for connecting to SQL server. Solution If you have Docker file ready, it should somewhat look like below file -  FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build-env WORKDIR /app # Copy csproj and restore as distinct layers COPY /SampleAPI/*.csproj ./ RUN dotnet restore # Copy everything else and build COPY . . WORKDIR /app/SampleAPI RUN dotnet publish -c Production -o publish # Build runtime image FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 WORKDIR /app/SampleAPI COPY --from=build-env /app/SampleAPI .
