C:> %systemroot%\system32\inetsrv\appcmd set app "Default Web Site/OldApplicationName" -path:/NewApplicationName
You just have to change OldApplicationName and NewApplicationName as per your requirement.
.NET Entity Data Model template missing
So, as I do always started to write a sort of "Hello World" app. When I try to create the ADO.NET Entity Data Model, I could not find ADO.NET Entity Data Model template.
Is something wrong here? yep, we need to install Microsoft Visual Studio 2008 Service Pack 1 (iso). Here we go I have ADO.NET Entity Data Model template under my Data category.
There is more than one way...
Page load twice
This was the issue in my CSS code background-image:url(''), having a empty image URL.
I thought reloading the page twice an issue with my coding on page behind, but ultimately it was a CSS issue.
Let me tel me why an empty URL gives such a major issue. Once the page loads the firefox still tries to find the empty URLs so page loads twice but IE just replaces the empty URL with null value.
As I mentioned above this may not the exact cause for your problem but one of the following might cause your issue. Please visit the following URL (http://www.110mb.com/forum/how-to-stop-firefox-dual-pageloads-t27704.0.html) to see more possibilities. Hope this guides you to find the issue.
must be placed inside a form tag with runat=server
Content Holder (idea was to get the html of that area what evel loding in to that).
ContentPlaceHolder cph = (ContentPlaceHolder)Master.Controls[0].FindControl("master_content_holder");
var sb = new StringBuilder();
var sw = new StringWriter(sb);
var htmlTxtWr = new HtmlTextWriter(sw);
SmtpUtil smtpUtil = new SmtpUtil();
cph.RenderControl(htmlTxtWr);
I got this error exactly on the last line of code. As error message states our all controlls must be inside a form tag with runat = server (note you can't have form tags on child pages, do not try it, it won't work). I did a small dirty work as to fix this issue.
I just overrided the VerifyRenderingInServerForm mehtod on child page. For me it worked properly, as i didn't have any verification to be done on my page. Be carefull before use.
Drop emails in a folder
Instead sending an email we can configure the web.config to drop the mail in a local folder.
This is a good feature when it come to testing email on your application while developing.
Just add the following on the web.config
1: <system.net> 2: <mailSettings>3: <smtp deliveryMethod="SpecifiedPickupDirectory">
4: <specifiedPickupDirectory pickupDirectoryLocation="C:\testmails\"/> 5: </smtp> 6: </mailSettings> 7: </system.net>Following code will drop an email in your folder
1: var smtpClient = new SmtpClient();
2: var message = new MailMessage("from@from.com", "to@to.com");
3: message.Subject = "This is the mail subject";
4: message.Body = "this is the mailm body";
5: smtpClient.Send(message); Double click on the file in your C:\testmails\ folder it will open up on outlook
as an email.
Take asp.net web site offline App_Offline.htm
Do not need to do any setting on ISS, instead just move in an HTMl file named
App_Offline.htm . This will stop responding to any web request but as the response
this file passes until you remove it from the root or rename it.

Dotnetnuke System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission
I got this error when I try to install Dotnetnuke 05.04.02 on my computer on Wndows 7 and IIS7. There was no proper solution for this on the web, but I just change the application pool identity to NetworkService and application worked as expected.
Steps :
Go to IIS and select Application Pools.
Select the DNN web pool on right hand pane.
On Actions press Set Application Pool Default link.
Change the Identity under Process Model to NetworkService

Using JQuery on blogspot
As I use JQuery these days, I just though how I can use JQuery on my blog.
I tried to do this and found It’s very easy to use it with blogger. Just a few steps
make this possible. You might be wondering where you can place the JQuery file in
blogger. Google has host these file on the following path “http://ajax.googleapis.com/ajax/libs/jquery/”. Just have to select the version you prefer to use.
Just see the following steps.
Step 1:
Add the following code between header tags of your blog’s HTML.
<head>
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js' type='text/javascript'/>
</head>
Example:
Step 2:
Add the functions in between header tags as follows,
<head>
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js' type='text/javascript'/>
<script type="text/javascript">
function MouseOn() {
$(document).ready(function() {
$("img").toggleClass("newClass");
//$("#testPara").append("Shiran the greatest" + count );
});
}
</script>
</head>
Example :
Step 3: (Optional)
If there are any CSS involved embed them also in between header tags as follows
<head>
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js' type='text/javascript'/>
<script type="text/javascript">
function ChangeCSS() {
$(document).ready(function() {
//here this will toggle CSS classes on an event
$("img").toggleClass("newClass");
});
}
<style type="text/css">
.toggler {width: 100px; height: 200px;}
.newClass {width: 500px; height: 866px;}
</style>
</script>
</head>
Need to call the above ChangeCSS() JS function where this need to be done.
Example:
this maight be in post or a HTML/JavaScript gadget
<img class="toggler" src="http://1.bp.blogspot.com/_8fX3E/S-L0RblzI/AAAADtQ/nB8kJYc/s200/108_f0.jpg" onmouseover="ChangeCSS()"/>

Enable JQuery intellisense in VS 2008
I just started to do some JQuery on one of my VS projects. I found that we can have intellisense on VS2008. To make this available I had to do some installations and follow few steps to get intellisense on VS2008, I hope these would helpful you as well in projects.
Step 1:
Install VS 2008 SP1, you can get it here
Step2:
Install VS 2008 Patch KB958502, you can get it here
Step3:
Download JQuery js file and JQuery vsdoc.js, both these should be one version
Eg: jquery-1.4.1-vsdoc.js and jquery-1.4.1.js (version may be differ on the version you have downloaded).
Put both files in the same place in your project.
now you are ready to use. You will get intellisense and auto complete features on VS2009
using statement in C#
This is a nice little statement which reduces our coding and minimises prone to errors.
There are many situations we have to Dispose the object we created. Example
string connString = "Data Source=localhost;Integrated Security=SSPI;Initial Catalog=MyDB;";
SqlConnection myConnect = new SqlConnection(connString);
SqlCommand cmd = myConnect.CreateCommand();
cmd.CommandText = "SELECT * FROM MyTable";
myConnect.Open();
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read())
{
Console.WriteLine("{0}\t{1}", dr.GetString(0), dr.GetString(1));
}
dr.Dispose();
myConnect.Close();
myConnect.Dispose();
Here on above example I just try to connect to a database and take out all records from MyTable.
I have created a SqlConnection object named myConnect and a SqlDataReader object named dr, at the very bottom of the code snippet I have disposed those two objects using Dispose() method.
What will happen if I forget to dispose these objects? memory issues, using statement is a remedy for this and its makes code more readable, robust and clean. I will recode the above code snippet with using “using ” statement.
using (SqlConnection myConnect = new SqlConnection(connString))
{
SqlCommand cmd = myConnect.CreateCommand();
cmd.CommandText = "SELECT * FROM MyTable";
myConnect.Open();
using (SqlDataReader dr = cmd.ExecuteReader())
{
while (dr.Read())
{
Console.WriteLine("{0}\t{1}", dr.GetString(0), dr.GetString(1));
}
}
}
Don’t you feel more comfortable with using statement? Let me just go bit deep on using statement, how does this work? Actually when an using statement compiled, the CLR converts it to a try and Finally block. It does three things, get the resources (SqlConnection ), encloses in a try block and disposes in the Finally block. Hope you enjoyed …………….
Referring to another config file in web.config file
Instead of having all connection string detail on web.config file , we can create a new configuration
whatEvernName.config eg(connectionString.config) and have all connection string details in this new .config file.
Please go through the code below to understand this.
web.config
<connectionStrings configSource="connectionString.config" />
connectionString.config
<connectionStrings>
<clear />
<add name="myConnection" connectionString="myConnectionString" providerName="System.Data.SqlClient" /> </connectionStrings>
This is really nice feature when you have a lot of tags in your web.config file,
as it increases the readability. There is another cool feature which is very useful for
developers when it’s come to development or rather I would say debug the code.
Most of the times we have our connection string in one file and there is a high chance to forget
to change live connection string properties to test environment properties, I have made such a mistake and had to restore a latest database backup, but luckily there was not any data lost.
This cool feature avoids taking place such a bad mistake. Try this it’s is really nice and you do not have to keep on changing your web.config’s conection string values. As in above code snippet you can have two config files as connectionString.debug.config and connectionString.releaase.config
VS IDE will take the valuse depending on what you have selected, debug or release. Isn’t it cool.
Enjoy…
GridView column text wrap width
We had a grid view and one of the column data was dynamically bound. Most of the time this grid goes out of the sreen area and makes user to scroll to right, because of this dynamically bounded column's text lenght. There were some solutions on the web but none of them working properly. Solution is, put the text inside a paragraph tag “<p> your text here</p>”

How do I get the return value and dataset when calling a stored procedure in a typed DataSet object?
There is no direct way to retrieve the returning value from a stored procedure in typed DataSet object. To accomplish this what you have to do is just add a new method in the partial class of the generated table adapter. Ill show how to do this step by step.
Consider the following stored procedure, which returns a dataset plus a return value. (not a complicated SP). In this case I just return 0 from the SP.
CREATE PROCEDURE [dbo].[GetUser]
@EmailID VARCHAR (100)
AS
BEGIN
SELECT
[UserID],
[FirstName],
[LastName],
[Phone]
FROM
[dbo].[User]
WHERE
[EmailID] = @EmailID
RETURN 0
END
Now add the method following method in the partial class of the generated table adapter. In my case it's UserTableAdapter.
partial class UserTableAdapter
{
public object GetReturnValue(int commandIndex)
{
return this.CommandCollection[commandIndex].Parameters[0].Value;
}
}
Ok, now you can retrieve the return value plus the dataset,
private DSTableAdapters.UserTableAdapter _userAdapter = null;
protected DSTableAdapters.UserTableAdapter Adapter{
get{
if (_userAdapter == null)
_userAdapter = new DSTableAdapters.UserTableAdapter();
return _userAdapter;
}
}
This is the method that retrieve dataset and the get return value by calling the method (GetReturnValue(int commandIndex) ) we added in to generated partial class
public int GetUser(string emailid)
{
int success ;
try
{
DS.UserDataTable userDataTable = Adapter.GetUser(emailid);
if (userDataTable.Rows.Count > 0)
{
//assingning to variables
FirstName = userDataTable.Rows[0]["FirstName"].ToString();
LastName = userDataTable.Rows[0]["LastName"].ToString();
success = int.Parse(Adapter.GetReturnValue(0).ToString());
}
}
catch (Exception ex)
{
//write you exception handling
}
return success; }
Limiting Textarea length
Here is the code snippet.
Limiting Textarea length
<'textarea name="txaDescription" onkeypress="return maxLength(this, 250);" textarea>
and the javascript
function imposeMaxLength(Object, MaxLen)
{
return (Object.value.length <= MaxLen);
}
