<a href="#" style="position:relative;"> Tool Tip Right <div class="tool-tip slideIn right">ini tooltip, di sini bisa nulis apa saja.</div></a><br><br>

/* tooltip */

	color: #fff;
	background-color: rgba( 0, 0, 0, .7);
	text-shadow: none;
	font-size: .8em;
	visibility: hidden;
	-webkit-border-radius: 7px; 
	-moz-border-radius: 7px; 
	-o-border-radius: 7px; 
	border-radius: 7px;	
	text-align: center;	
	opacity: 0;
	z-index: 999;
	padding: 3px 8px;	
	position: absolute;
	cursor: default;
	-webkit-transition: all 240ms ease-in-out;
	-moz-transition: all 240ms ease-in-out;
	-ms-transition: all 240ms ease-in-out;
	-o-transition: all 240ms ease-in-out;

	height: 0px;
	width: 0px;
	border: 6px solid transparent;
    border-top-color: rgba( 0, 0, 0, .7);	

/* default heights, width and margin w/o Javscript */

	height: 300px;
	margin-left: -43px;

/* tooltip on focus left and right */

.on-focus .tool-tip.left,
.on-focus .tool-tip.right{
	margin-top: -19px;

/* on hover of element containing tooltip default*/

*:not(.on-focus):hover > .tool-tip,

Menentukan Name Server pada ConnectionString

Saya membuat sebuah web aplikasi dengan C#.Net, ada sebuah kebutuhan untuk koneksi ke database MySQL. Berikut adalah Connection String untuk koneksi ke MySQL dari C#.Net yang saya buat:

MyConnectionString = “Server=; port=3306;Database=MyDatabaseName;Uid=MyUID;Pwd=MyPwd;”;

itu bukan IP sebenarnya ya. hhehe..
Sebelumnya, web aplikasi ini saya simpan di server lokal. Dengan Connection String yang sama (Server name menggunakan IP), bisa berjalan dengan baik.

Ketika harus di-upload ke cloud, saya mengganti name server itu dengan IP Cloud. Ternyata koneksi bermasalah.

Solusinya adalah, mengganti nameserver dengan “localhost”. keseluruhan ConnectionString itu jadi:

MyConnectionString = “Server=localhost; port=3306;Database=MyDatabaseName;Uid=MyUID;Pwd=MyPwd;”;

and it works fine :)

Nope, nothing to do with Haskell.

This admittedly boring post is about two specific problems with IIS 7.5 and WCF which wasted so much of my time that I thought it would be worth to  document them.

If you have a WCF service hosted as an ASP.NET application in IIS, you may encounter the following exception on the client side:

System.ServiceModel.ProtocolException: The content type text/html of the response message does not match the content type of the binding (application/x-gzip). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 75 bytes of the response were: ‘The page cannot be displayed because an internal server error has occurred.’.

—> System.Net.WebException: The remote server returned an error: (500) Internal Server Error.

at System.Net.HttpWebRequest.GetResponse()
at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout)
— End of inner exception stack trace —

The system I’m maintaining has gzip-binary-encoded data over HTTP, so the first…
