Enterprise library is precompiled code provided by MicroSoft. Enterprise library provides inbuilt functions to do jobs which are common. Here I am giving code for reading excel sheet using Enterprise library.

The following sample code gives an idea to use enterprise library:

String path = @"filepath";

String ConnectionString = @"Data Source=" + path + ";Provider=Microsoft.ACE.OLEDB.12.0; Extended Properties=Excel 12.0;";

DbProviderFactory factory = DbProviderFactories.GetFactory("System.Data.OleDb");

using (DbConnection connection = factory.CreateConnection())

{

connection.ConnectionString = ConnectionString;

using (DbCommand command = connection.CreateCommand())

{

connection.Open();

command.CommandText = "SELECT * FROM [Sheet1$]"; //Sheet1 here is the name of the sheet which is to be read

using (DbDataReader reader = command.ExecuteReader())

{

while (reader.Read())

{

}

Hello All:

There are cases when we need a customized JavaScript popup for getting user input.
On the net I found a good article on creating a JavaScript popup, here I am giving a customized version of mine which I used in one of my applications.

Javascript:

var ae_cb = null;
var isCLicked = false;
var isCancel = false;
function getObjectById(id) {
return document.getElementById(id);
}

function getValue(func,txtHeading) {
ae_cb = func;
var lblMessage = getObjectById('lblMessage');
lblMessage.innerText = txtHeading;
getObjectById('txtInput').value = "";
var div = getObjectById('mainDiv');
div.style.display = "block";
}

function getClick(click) {
var div = getObjectById('mainDiv');
div.style.display = "none";

if (!click) {
isCancel = true;
isCLicked = false;
ae_cb(null);
}
else {
isCancel = false;
ae_cb(getObjectById('txtInput').value)
}
}

function SetValue(valueSet) {
var hiddenF = getObjectById('hdnfValue');
if (parseFloat(valueSet) > 0) {
hiddenF.value = valueSet;
if(isCLicked)
getObjectById('LinkButton1').click();
}

else {
if (!isCancel) {
alert("Please enter number more than 0");
isCLicked = false;
}
}
}

function getCloneCount() {
isCLicked = isCLicked ? false : true;
if (isCLicked) {
getValue(SetValue, "Enter number of rows to be cloned");
}
else {
return true;
}
return false;
}

ASP Code:
Default.aspx:

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">
<title></title>
<script src="Scripts.js" type="text/javascript"></script>
<link href="Stylesheet.css" rel="stylesheet" type="text/css" />
</head>
<body>
<form id="form1" runat="server">
<asp:LinkButton ID="LinkButton1" runat="server" onclick="LinkButton1_Click">LinkButton1</asp:LinkButton>
<asp:LinkButton ID="LinkButton2" runat="server">LinkButton2</asp:LinkButton>

<div id="mainDiv" class="timeSheetDiv" >
<table border="1">
<tr><td colspan="3" style="text-align:center"><label id="lblMessage"></label></td></tr>
<tr><td colspan="3" style="text-align:center"><input type="text" id="txtInput" /></td></tr>
<tr><td style="text-align:center"><input id="btnOk" type="button" value="Ok" onclick="getClick(1)" /></td><td> 
</td><td style="text-align:center"><input id="btnCancel" type="button" value="Cancel" onclick="getClick(0)"/></td></tr>
</table>
</div>

<asp:HiddenField ID="hdnfValue" runat="server" />
</form>

</body>
</html>

Default.aspx.cs:

Modify
protected void Page_Load(object sender, EventArgs e)
{
LinkButton1.Attributes.Add("onclick", "return getCloneCount();");
}

protected void LinkButton1_Click(object sender, EventArgs e)
{
Response.Write(hdnfValue.Value);
}
